EDITOR’S

WELCOME

A

fter a disruptive and unpredictable year, we have finally made it to 2021. While all of the challenges of 2020 did not completely disappear when the clock struck midnight, we’re being cautiously hopeful of a successful and fulfilling upcoming year for the infrastructure industry.

Over the last few issues we’ve talked about the sector’s role in the postCOVID economic recovery, and this year we should start to see this more in action with the progress of major projects across the road, rail, port and airport sectors.

A recent Infrastructure Australia (IA) study that looked at the future of infrastructure beyond COVID-19 found that the sector proved itself to be relatively resilient to the pandemic and that the impacts of the last year have helped to accelerate trends such as digitisation, more local and regional infrastructure use, and service innovations and adaptations.

Infrastructure Australia is also set to release its 2021 Priority List in February, and this year it is partnering with Infrastructure magazine for a virtual launch event. The Priority List is a critical document for Australia's infrastructure sector, and we’re very excited to be working with IA to get this key information out to you. For more information and to register, visit www.ipllaunch2021.com.au.

Infrastructure Partnerships Australia also recently released its 2020 Australian Infrastructure Budget Monitor, which showed that across Australia, governments are investing $225 billion in infrastructure over the next four years – an increase of $46 billion from last Budget season. This funding aims to combat the economic downturn from COVID-19, with NSW set

to spend the most – $84 billion over the next four years.

NSW and Victoria ($70 billion) combined account for 68 per cent of total infrastructure funding across the country, so expect to see some more funded projects start to come to fruition this year.

We’ve touched on a few of these topics in this issue of the magazine, with articles on private investment, new service models and opportunities for reform. This edition also looks at the role of software, communications and connectivity in the sector, as well as updates in rail, from asset management to innovation deficits, funding and projects. The rail sector is one area in particular that will be stepping up when it comes to supporting the country’s economic recovery.

As we’ve seen from multiple COVID clusters that broke out over the New Year break, causing rapidly changing restrictions and border closures, there is still a lot of uncertainty and risk around domestic travel, and this seems likely to continue, potentially even once vaccine distribution begins.

This means that for the industry, virtual events are still the best way to network and find out new information and updates on the sector. Infrastructure magazine will be running the Critical Infrastructure Summit virtually over two weeks in April to keep you up to date on projects, industry outlook, funding, asset management, disaster management and the future of infrastructure. Head to www.criticalinfrastructure.com.au to register for free.

In addition, we’ve got other exciting plans for 2021 across our print and digital channels, and will continue to be the voice of the industry as the sector works to meet the post-COVID infrastructure demand.

$44 MILLION INVESTMENT INTO NARRABRI TO TURRAWAN RAIL UPGRADE

T

he Federal Government will invest $44.7 million in the Australian Rail Track Corporation’s 35km upgrade of the Narrabri to Turrawan Line between the Hunter Valley Coal Network and Inland Rail.

The project will deliver a corridor from Northern NSW to the Port of Newcastle capable of 25 Tonne Axle Load (TAL) trains at 80km/h. Currently the 35km section of track is only capable of accommodating 20.5TAL and comprises steel and timber sleepers, aging 47kg/m rail for most of the line, and poor track geometry, formation and ballast in some locations, resulting in limitations on its capability.

The upgrade represents a significant benefit to agricultural producers transporting grain, cotton and other primary products from Northern NSW to domestic and export markets, as well as the opportunity to back-haul materials, supplies and agricultural inputs into the region more efficiently and cost-effectively.

Deputy Prime Minister and Minister for Infrastructure, Transport and Regional Development, Michael McCormack, said, “We are investing in this project to greatly improve the quality and capacity of this crucial rail connection, better linking northern New South Wales, Inland Rail and the Port of Newcastle.

“This upgrade will allow longer and heavier freight trains from Northern NSW – transporting food and fibre – to access the Newcastle and Sydney ports.

“Greater volumes of freight moved on each train will reduce transport costs and make Australian exports more competitive.”

The project will see the steel and timber sleepers replaced with heavy-duty concrete ones, as well as upgrading critical level crossings and improving the rail quality on the Narrabri Coal Junction to Turrawan and the Turrawan to Narrabri North sections.

The project will commence in mid2021 and aims to be completed in 2023.

RUNWAY UPGRADE COMPLETE AT GOLD COAST AIRPORT

A

$5 million upgrade of the Gold Coast Airport runway has been completed, with asphalt resurfaced on the southern 450m of the runway and 280m of adjoining taxiways recently grooved – a process which allows water to run off the surface under aircraft tyres.

The window for night works was increased due to fewer late night and early morning flights during COVID-19 travel restrictions, allowing the project to be completed sooner and delivering a cost saving of about five per cent.

Gold Coast Airport COO, Marion Charlton, said airside infrastructure projects required many months of careful planning and coordination.

“Critical maintenance projects like these are forecasted years in advance,” Ms Charlton said.

www.infrastructuremagazine.com.au

“The overlay was a priority project that we needed to deliver and the reduction in flights provided a benefit, allowing the project to happen more quickly and with a cost saving.

“This essential investment is critical to ensuring safe aircraft operations at Gold Coast Airport now and into the future.”

Work was undertaken at night to limit any operational impact as a result of closing the runway.

The project, delivered by Fulton Hogan, covered a total area of 32,000m², requiring 6,500 tonnes of asphalt.

A crew of up to 100 was on-site each night, completing the works in sections of about 90m per night on average.

Overlay projects are generally undertaken every 10-15 years. The other 2km of the runway was resurfaced in 2016.

COFFS HARBOUR BYPASS

GETS GREEN LIGHT

T

he Federal Government has given the Coffs Harbour bypass, the town’s biggest ever infrastructure project, the green light following its assessment and approval under the Environment Protection and Biodiversity Conservation Act (EPBC Act).

Deputy Prime Minister and Minister for Infrastructure, Transport and Regional Development, Michael McCormack, said the 14km bypass, which received official planning approval, is one of the 15 major projects that the Federal Government committed to fast-tracking in June 2020.

“The bypass is going to take more than 12,000 vehicles a day out of the centre of Coffs Harbour, reduce travel times by as much as 12 minutes by bypassing 12 sets of traffic lights, and improve safety for all road users,” Mr McCormack said.

“Transport for NSW has now received the final stamp of approval after close scrutiny by the NSW Minister for Planning and Public Spaces, and the Australian Minister for the Environment.

“This approval includes the proposed tunnels at Roberts Hill, Shephards Lane and Gatelys Road, as well as assessing the project for its social, environmental, heritage and economic impacts, and gives the project team the green light to go ahead with major work.”

NSW Minister for Regional Transport and Roads, Paul Toole, said the Pacific Highway was a major contributor to Australia’s economy, and the Coffs Harbour bypass would be a key link in this vital piece of the nation’s infrastructure.

“This bypass alone will support about 12,000 jobs over the whole lifecycle of the project, providing about 2,000 local jobs for the community of Coffs Harbour during construction, which shows how serious we are about investment in regional NSW,” Mr Toole said.

“The local community has played a huge role in developing this project – from helping shape the design for the bypass to engaging with the experts in the field to ensure we can get on with the job of delivering on our promise.”

The project is expected to take around five years to build, weather permitting.

PORT OF TOWNSVILLE CHANNEL UPGRADE PROJECT’S LARGEST CONTRACT AWARDED

T

he Port of Townsville has announced the winner of the largest contract of the $232 million Channel Upgrade project, with the contract awarded to Hall Contracting.

The works include capital dredging to widen 14.9km of sea channels over two years and reclamation of 62 hectares of land through beneficial reuse of dredged material.

Employing a local workforce of more than 70 full-time employees, the contract follows the extensive work over the past 18 months to build a 2.2km rock perimeter wall to receive the material.

Port of Townsville Chief Executive Officer, Ranee Crosby, said Queensland-based Hall Contracting has partnered with Townsvillebased Pacific Marine Group to offer extensive experience in dredging and reclamation.

The pair has committed to almost 100 per cent of this project being resourced from Queensland-based businesses.

“Hall Contracting has presented the best offer to complete the works,” Ms Crosby said.

“Their strong commitment to local industry and First Nations people’s participation, as well as employment and learning opportunities for tertiary students, apprentices and trainees, presents significant opportunities for our region.

“Over the course of the project, they will provide meaningful training across a range of vocations including vessel crew, marine engineers, diesel fitters, hydraulic fitters, boilermakers, earthmoving operators and dredge operators.”

The Channel Upgrade project will widen the current shipping channel from 92m to 180m at the inshore (Port) end, tapering to 120m wide in the Sea Channel, increasing the size of cargo, cruise and defence vessels able to access the Port of Townsville.

The Port has committed $17 million for environmental monitoring and management programs as part of the project, including those covering dolphins, turtles, seagrass, coral and shorebirds.

An Independent Technical Advisory Committee is also providing expert oversight of the monitoring programs during the capital dredging works.

Hall Contracting is expected to begin capital dredging in May 2021.

The Channel Upgrade is a joint project of the Queensland and Australian Governments, and Port of Townsville Limited.

The Channel Upgrade is a key initiative under the Townsville City Deal signed in December 2016.

PRIVATE OPERATOR TO TAKE OVER ADELAIDE’S RAIL NETWORK

T

he South Australian Government appointed a private operator to take over the running of Adelaide’s rail network from 31 January 2021.

Keolis Downer was announced as the new operator of the rail network.

Minister for Infrastructure and Transport, Corey Wingard, met with both the Rail, Tram and Bus Union (RTBU), and a representative from a breakaway group of local train drivers, to discuss the upcoming transition and future employment and training opportunities.

During the meetings, Mr Wingard made it clear the timeline won’t be shifting and that the current offer on the table for drivers to transfer over to Keolis Downer won’t be changed.

“As it stands, a total of 83 drivers have accepted an offer of employment with Keolis Downer and another 88 remaining on the government payroll will be made available to Keolis Downer to ensure essential public transport services continue to be delivered to the community,” Mr Wingard said.

Drivers who’ve accepted a job with Keolis Downer have secured permanent ongoing employment with no loss of terms or conditions, a transfer of all entitlements, free public transport travel, and a $15,000 incentive payment.

They have also secured a commitment of no forced redundancies for the next three years, and the right to transfer to the future operator at the end of Keolis Downer’s contract.

In late-2020, a new enterprise agreement was also reached providing a two per cent per annum pay rise for train drivers and other rail staff.

The RTBU had been pushing for a $65,000 incentive payment and a four per cent per annum pay rise over four years despite both nurses and tram drivers accepting a two per cent rise just months earlier.

“From next month Keolis Downer will also start delivering training programs for drivers to join the workforce,” Mr Wingard said.

“Experienced drivers from other networks will undertake a 22 week program and will be ready to join the workforce in August.

“Further intakes for 33 week-long programs in May and September 2021, and also early in 2022 for new drivers will mean that progressively drivers made available to Keolis for the transition will no longer be required and will be moved into roles elsewhere in government.

“More than 1,000 applications were received by Keolis Downer for train driver positions and it’s clear there’s plenty of people excited and eager to join the sector.

“This transition will not only deliver better services but will also mean very significant savings to SA taxpayers.”

ADOPTING IEC-62443 STANDARDS

TO PROTECT AGAINST CYBER ATTACKS With increased awareness of cyber security attacks on industry, companies are starting to understand the devastating production and financial losses these attacks are capable of. Industrial networks are often full of legacy hardware that was never envisaged to be connected to the internet. This has led to the rise in targeted attacks on these networks and the need to implement security mechanisms to avoid exploitation and compromise.

T

he IEC-62443 standard was developed to assist with providing an international framework to work towards securing vulnerabilities in Industrial Automation and Control Systems (IACS) networks. Guidelines for basic, medium and high security levels within the standard denote increasing levels of security policy adoption.

A basic level includes items such as default password changes, account timeouts and enabling trusted access to the device. A high level of adoption may include device configuration file encryption.

Adoption of any level of IEC-62443 is optional and dependent upon a risk assessment of the network. While not a guarantee of threat immunity, it does serve as an excellent and agreed upon starting point.

Moxa EDS-518E Managed Ethernet Switch.

IMPLEMENTING THE HIGHEST LEVEL OF SECURITY To assist with adoption of the highest level of IEC-62443 conformity, Moxa has developed an “E” series managed switch range. These easy-to-install and configure switches allow the user to implement the highest level of the IEC62443 standard – with security built into the component. Not limiting itself to just switches, Moxa has also developed a range of compliant devices, including serial to Ethernet servers, protocol gateways, firewalls and wireless access hardware that are also IEC-62443 aware.

Obtaining an understanding of how secure your network is may seem like a difficult and long winded process, however Moxa’s MxView is the component supplier’s answer to a Network Management System (NMS).

While it will effortlessly discover all Moxa and non-Moxa hardware on your network, automatically draw a topology map and provide an excellent overview of your network, it can also do a lot more.

The latest version will provide you with a colour coded visual of how secure your network connected devices are.

MxView Series Software.

Four colour codes relate directly to the IEC-62443 standard (open, basic, medium, high). MxView allows you to centrally view security events as well as provide the ability to mass configure settings from a central location.

Being able to deploy changes and updates of settings relating to the IEC standard ensures a uniform deployment across the network. The MxView software suite is licensed based on the number of network connected devices being monitored. This makes it an extremely cost-effective network monitoring tool, with the added benefit of the security awareness monitoring, link bandwidth monitoring, and centralised administration of your network.

A WORD FROM INFRASTRUCTURE AUSTRALIA

Infrastructure Australia has released its findings from research into how the COVID-19 pandemic is changing the way Australians use infrastructure, the impact on long-term planning and development, and the key trends that have emerged.

A

s the COVID-19 pandemic spread, Australia's governments took early action, introducing travel bans, lockdowns and border controls, and supporting domestic supply chains. Communities adopted social distancing and moved to working from home.

While these early measures successfully contained national case numbers, they prompted profound changes to the way people moved, consumed and worked, which changed patterns of infrastructure use.

The continuation of infrastructure construction across major projects was a key source of economic activity and employment at the height of the COVID-19 pandemic in Australia. However, months of lockdowns, social distancing and working from home has driven sweeping changes in how Australians use critical infrastructure.

Although the pandemic put our infrastructure to the test over the past year, Australia’s governments and infrastructure providers navigated dramatic changes to community behaviour and network requirements, and rapidly adjusted their service provision across the transport, telecommunications, digital, energy, water, waste and social sectors.

Infrastructure Australia’s new report, Infrastructure Beyond COVID 19: A national study on the impacts of the pandemic on Australia, found that compared with other OECD countries, our infrastructure networks have proven to be resilient under pressure and open to innovation.

Developed in collaboration with L.E.K. Consulting, our report presents a moment-in-time snapshot of how the pandemic has

changed the way we use infrastructure, and considers which of these changes could have lasting impacts on how we plan, fund and deliver the services we all rely on.

It finds that while COVID-19 has put a pause on the traditional driver of infrastructure – Net Overseas Migration – the pace of change in the sector has generally increased, with new emerging trends.

Major shifts in how Australians work, travel and consume goods and services in the wake of COVID-19 has driven the redistribution of existing demand, mode or channel switches, and acceleration of longer-term trends that were already underway.

A RAPID SHIFT TO DIGITAL SERVICE DELIVERY We estimate that around four million Australians have been working from home since March 2020, representing 30 per cent of the total workforce. Our report found that a third of those people would like to continue doing so at least once a week, suggesting a permanent move towards a hybrid structure that will see a split of working time between the office and home – with significant impacts for infrastructure use.

Add to this 17.2 million telehealth consults between March and June 2020, teaching curricula and students moving online, and countless Zoom meetings, the past year has been characterised by a rapid shift from physical to virtual interaction with our health and safety front of mind.

Not surprisingly, this put significant strain on our broadband networks, with spikes in NBN bandwidth congestion growing to an average 60 minutes per week per www.infrastructuremagazine.com.au

A WORD FROM INFRASTRUCTURE AUSTRALIA tourism and population growth, and are experiencing less severe COVID-19 impacts. Strengthened regional cities, huband-spoke service models, and improvements to liveability and affordability can refocus regional investment.

The longevity of these changes is uncertain, however the impacts are likely to persist for some time as Australians continue to seek more affordable housing outside of the inner metro areas. If this trend continues, we could see reduced demand for urban transport and increased pressure on broadband networks in regional centres.

service at the height of the lockdowns in March 2020, and increased instances of customer complaints – particularly from small to medium-sized businesses.

The impact of large-scale remote working led to a surge in usage, with telecommunication providers responding by leveraging extra capacity in the network.

Latent broadband capacity was released to cope with the surge in demand – an example of responsive repurposing of infrastructure and assets that speaks to the resilience and adaptability of the network.

However, some suburban areas experienced network outages, and many regional Australians experienced internet access issues during lockdown restrictions, impacting their ability to work from home or undertake schooling remotely.

Working from home also catalysed a rapid uptake of digital collaboration tools – accelerating developing trends and triggering investment in cloud-based systems and cyber security.

Australians also accelerated their move to online retail channels and digital services, resulting in a substantial uplift in online sales and increased broadband network congestion.

The pandemic drove a 100 per cent growth in monthly online retail, five times the annual growth recorded in 2019, resulting in a growth in parcel delivery and micro-freight.

RENEWED VIBRANCY IN REGIONAL AREAS As a result of social distancing and work from home opportunities, some households embraced the opportunity to move away from dense metro areas, resulting in a 200 per cent increase in net migration from capital cities to regional areas.

This caused an immediate increase in capital city vacancies, while rental demand increased in regional and coastal towns including Newcastle, Wollongong and the Sunshine Coast.

Some regions are also seeing a local boom of regional www.infrastructuremagazine.com.au

RECOGNISING THE VALUE OF PARKS AND RECREATION In 2020, Australians have evidently cherished greenspaces, both in metro areas and national parks.

There has been a 23 per cent increase in our use of national parks and greenspaces nationally. Research also shows that 87 per cent of Australians have noticed a positive shift in community attitudes towards urban green space, particularly amongst those living in high-density areas.

In a survey conducted by the NSW Department of Planning, Industry & Environment, 46 per cent of respondents claimed to have spent more time in parklands and gardens with many (94 per cent) using these spaces to undertake personal exercise.

Further, 72 per cent of NSW survey respondents cited that local parks have been ‘especially useful’ or ‘appreciated more’ during COVID-19, with Hermitage Foreshore, Western Sydney Parklands and Centennial Park visits up by around 144 per cent and around 100 per cent respectively compared to the previous year.

Generally, increased local activity including intense use of local greenspace could lead to reduced demand on toll roads.

Policy reforms and programs supporting access and uptake could drive even greater sustainability.

MAPPING THE LONG-TERM IMPACTS ON PUBLIC TRANSPORT USE Across the country, public transport providers moved quickly to support social distancing and hygiene measures, making improvements such as increased cleaning, and applying real-time occupancy data to public transport in line with social distancing initiatives.

However, in a reversal to the earlier trend of increasing public transport use, patronage in most cities fell to 10–30 per cent of normal levels in the initial lockdown and settled at a ‘new norm’ of 60–70 per cent of pre-COVID-19 levels. Traffic levels rebounded quickly, along with an uplift in second-hand car purchases, potentially indicating that higher car mode share may persist for some time.

A key focus for government and industry in 2021 will be to understand the structural impacts of COVID-19 on travel demand within Australia.

Together with the Bureau of Infrastructure and Transport Research Economics, Infrastructure Australia has convened a COVID-19 Cross-jurisdiction Roundtable to facilitate the exchange of ideas, techniques and tools for considering the long-term impacts of COVID-19 in travel demand models.

Taking a collaborative approach, we are working with industry, sector experts and thought leaders across government to understand how COVID-19 has changed the way we use infrastructure.

This will inform the Australian Infrastructure Plan, a major reform document that will provide a roadmap for the infrastructure sector to support recovery from the impacts of the pandemic, due for release in mid-2021.

DO WE NEED PRIVATE INVESTMENT TO FUND RECOVERY?

by Marie Lam-Frendo, CEO, Global Infrastructure Hub

March 2021 // Issue 18

INDUSTRY INSIGHTS

As stimulus spending ramps up, a ten-year trend study shows private investment in new infrastructure has declined since 2010.

I

nfrastructure is the backbone of developed and emerging economies worldwide. Yet, even as many countries turn to infrastructure stimulus to help drive COVID-19 recovery, the $15 trillion global infrastructure financing gap stands as a stark reminder of what the public sector has not been able to achieve alone.

The latest Global Infrastructure Hub (GI Hub) report, Infrastructure Monitor 2020, shows declining private sector investment in new infrastructure, despite the appealing riskreturn profile of infrastructure investments. Private investment in infrastructure through primary market transactions is only about US$100 billion per year, down from US$156 billion in 2010. This figure is a drop in the ocean compared to the US$15 trillion global infrastructure financing gap that the GI Hub calculated in 2017 based on projections to 2040.

Currently, the industry is taking a hard look at its objectives and practices in light of what the pandemic has taught us about the role infrastructure plays in inclusivity, resilience and other essential aspects of society. This presents a unique opportunity for the public and private sectors to build on their alignment of purpose to increase investment and close, together, the financing gap.

GATHERING MOMENTUM AROUND SOCIAL IMPACTS A 2019 Global Infrastructure Investor survey by GI Hub revealed that 97 per cent of investors now believe environmental, social and governance (ESG) factors are important considerations in infrastructure investment decisions, an increase from 86 per cent in 2016.

This widespread recognition by infrastructure fund managers, lenders and investors appears only to have strengthened since the global pandemic. There is a distinct shift in emphasis from viewing ESG factors as useful considerations to seeing them as future-focused must-haves.

This can only work in infrastructure’s favour for attracting private investment. www.infrastructuremagazine.com.au

SOME CHALLENGES REMAIN IN ATTRACTING PRIVATE INVESTORS There are a few reasons why investors are looking the other way when it comes to investing in infrastructure.

Firstly, there are limited opportunities for investment as the number of public-private partnerships (PPPs) shrinks globally.

Infrastructure Monitor showed that private participation in PPP projects has gradually declined as a share of private infrastructure investment – falling from 36 per cent in 2010 to 28 per cent in 2019. There is also a shortage of bankable projects and fewer privatisations coming to market.

Secondly, risk-adjusted returns have become less attractive over the last decade with returns dropping due to serious competition among providers. The risk of infrastructure projects for investors is perceived to be high, particularly if the private sector is being asked to carry the burden of excessive risk. This perception is challenged by Infrastructure Monitor, as it found that infrastructure loans on average perform like an investment grade security by year ten in high-income countries, and by year 14 in middle and low-income countries, and even faster in PPPs. From a performance perspective, our industry can raise awareness that infrastructure does not perform like other asset classes in having increasing default rates over time. And increasingly, we have the data to show this. In addition to the composite view provided in our Monitor 2020 report, there are the annual Moody’s publication of default and recovery rates of over 7,000 projects, and the EDHECinfra infra300 index of how unlisted infrastructure performs. The data is clear that once through the initial higher-risk phase (i.e. construction), infrastructure that is contracted or regulated by the state generally provides long-term, predictable and stable yields.

This finding is a clear signal to the world that infrastructure is a safe environment to play in, and the time is ripe for private investors to move away from focusing only on high-yield investment. By investing in infrastructure, the private sector March 2021 // Issue 18

can diversify its portfolio, have a longer retainer and have a social license to play.

Lastly, the industry can break barriers to private investment by understanding how the public sector can be a deterrent to private investment. Capital charges associated with infrastructure investment can push investors towards other asset classes, and low interest rates make investment by the state more attractive and affordable.

FINDING A WAY FORWARD As part of our work for the G20, the GI Hub recently conducted a market scan to understand the key challenges to mobilising private capital. We spoke to more than 40 investors, policymakers and market experts globally and identified three primary actions associated with attracting investment into infrastructure.

1. Ensure the availability of programmatic pipelines Governments need to develop a clear vision for their infrastructure development agenda and goals. Without the required clarity, they will not be able to develop a robust and properly prioritised pipeline of projects. A good example of an infrastructure project pipeline is the online Mexico Project Hub. Launched in 2017, the pipeline aims to accelerate private investment in Mexican infrastructure development. The first of its kind in the world, it has quickly strengthened Mexico’s ability to fund multiple large projects across the nation.

2. Navigate regulatory, political and economic uncertainty Infrastructure development is often politically complex, requiring the approval of multiple, diverse and sometimes competing stakeholder groups. Misaligned interests can inhibit projects. Therefore, governments need to create the proper

regulatory frameworks and economically robust environments if they are to nurture trust in their infrastructure programs.

One government that succeeded in this is Azerbaijan. Our InfraCompass, which quantifies the strength of countries' enabling environments, found it had the most improved regulatory framework of any InfraCompass 2020 country.

In 2018, Azerbaijan made resolving insolvency easier by making insolvency proceedings more accessible for creditors and granting them greater participation in the proceedings, improving provisions on the treatment of contracts during insolvency and introducing the possibility to obtain postcommencement financing. Then, in 2019, Azerbaijan made resolving insolvency even easier by providing for the avoidance of preferential transactions (transfers or payments made to unsecured creditors that result in a creditor receiving a preference over the remaining unsecured creditors at a time when the debtor was insolvent).

3. Develop projects with attractive risk-weighted return profiles Governments can keep in mind two key principles in the creation of their programs and projects: value creation (ensuring all projects have strong revenue potential) and value capture (ensuring key risks are mitigated and projects are appropriately financed to secure profitability). Projects that do not include plans for the fair and equitable generation and distribution of revenue will struggle to attract willing investors.

Activating private capital is key to closing the global infrastructure financing gap. The industry currently has an opportunity to explore investment options and create stronger partnerships between the public and private sectors, helping drive economic recovery in the short term while also driving longer-term economic and social outcomes.

FIXED AND PORTABLE INTERNET FOR REMOTE INFRASTRUCTURE PROJECTS Reliable, business-grade internet is critical to the ongoing operations of infrastructure projects. The necessity of connectivity for continued operation is just as pressing for permanent, fixed sites as it is for temporary, field sites.

T

he increasing adoption of remote monitoring systems and near real-time analysis of data flows to-and-from facilities has necessitated a constant, reliable internet service on every site. Activ8me Business Services’ satellite solutions can ensure sites can be connected online no matter how limited the local connectivity options may be.

With consistent data flows being a standard requirement both for operational functionality and safety and compliance, isolated locations can present significant challenges for infrastructure projects, with ongoing work dependent on continuous internet service in regions with very limited or no existing communications infrastructure.

With unlimited satellite internet for fixed and portable infrastructure sites, Activ8me’s custom-built hardware facilitates business-grade communications anywhere, with auto-aligning satellite dishes able to have a service operational in under ten minutes.

FIXED SATELLITE SOLUTIONS With custom contention rates and enhanced business SLAs, Activ8me’s solutions enable continuous, uninterrupted service, which is a common requirement both for operational functionality as well as safety and compliance.

REPLACING CRITICAL ASSETS

IN A PANDEMIC With COVID-19 restrictions significantly decreasing passenger numbers across all Australian airports in 2020, it became a suitable time to complete large maintenance and construction projects that would have otherwise caused extensive shutdowns. Brisbane Airport used this time to replace the entirety of its skylight that spans the length of the Domestic Terminal to maintain safety compliance.

A

s the gateway to Queensland for domestic and international visitors, Brisbane Airport's terminals have been designed to create a unique sense of space that makes a welcoming and lasting impression.

This sense of space encapsulates Queensland perfectly, capturing the warmth and light of the Sunshine State by bringing the outdoors in. At Brisbane Airport’s Domestic Terminal, visitors are welcomed by natural light that floods in overhead from the extensive skylight spanning 480m across the terminal’s ceiling. This architectural masterpiece has been a feature of the Domestic Terminal since its construction in the 1980s, providing opportunity for airlines and retailers to reap the resulting ambience and atmosphere.

Like all structures exposed to the elements, the skylight had reached the end of its life and required replacement in order to comply with relevant safety standards and protect the terminal from the elements.

Throughout the COVID-19 pandemic, Brisbane Airport Corporation (BAC), the operator of Brisbane Airport (BNE), reassessed all projects within the pipeline in order to prioritise those that were essential to ongoing operations.

Robert Scodellaro, Head of Project Services at BAC, said the skylight replacement project was identified as essential in order to ensure ongoing compliance of the Domestic Terminal.

“Construction for the replacement commenced in June, with practical completion being reached in October," Mr Scodellaro said.

FLEXIBLE CONSTRUCTION Despite COVID-19 not having a significant impact on the project, the decreased passenger numbers did allow for some flexibilities around construction.

28

March 2021 // Issue 18

“The skylight project could only be accessed from the roof of the terminal itself, with all materials being craned to that location.

“In order to have a crane operating in an active airside environment, there are a number of complexities to overcome, including the need for both internal and external exclusion zones.

“With reduced passengers and flights, the removal of aircraft bays from the allocation plan to enable the required exclusion zones resulted in a reduced impact to airlines," Mr Scodellaro said.

Though it wasn’t only the aircraft bays that were affected.

Despite operating in a heavily reduced capacity due to border restrictions, Brisbane Airport remained open and operational throughout the pandemic.

“Despite a significant decrease in passengers throughout the terminals, customer experience remained top-of-mind for any construction activities at the airport,” Mr Scodellaro said.

“This meant that all disruptive activities had to occur outside of operational hours, so they largely took place between 10pm and 4am."

RISK MITIGATION AND SAFETY PARAMOUNT The Principal Contractor, Box & Co, took each of these challenges in their stride, delivering the project on time and with an impeccable safety record. Box & Co’s Managing Director, Simon Box, said the project came with its challenges, but the team committed to a collaborative approach with BAC to find solutions.

“As a proud local business, safety is always our priority and this project gave us the opportunity to really practice what we preach and prove our capability.”

www.infrastructuremagazine.com.au

INDUSTRY INSIGHTS

With 1,090 glass panels and nearly a kilometre of roofing flashing that needed replacement, Box & Co facilitated 168 crane lifts to the rooftop, all from the airside environment.

“Prior to commencing on site, we worked through risk mitigation and safety procedures. Ultimately, we knew we had to send people to work from a rooftop at night in a really niche environment, so there were a number of challenges we had to design out of the process before we could commence,” Mr Box said.

“On top of the external environment, we were also very aware that the works were occurring above critical airport infrastructure such as check-in counters. We knew that any issues during the night shift could have an impact on airport operations the following morning.

“Scaffold harnessing and catch nets for dust and debris beneath the skylight internally are examples of the types of risk mitigation measures utilised throughout the project."

With the strong team dynamic at Box & Co, Simon Box knew he had the right people on board who would be able to deliver

www.infrastructuremagazine.com.au

this project to a high quality, and most importantly, safely.

“We are a small company, and we were in the height of a global pandemic – utilising local suppliers who we have built relationships with over the years was critical to us,” Mr Box said.

“Knowing that we were giving additional work to trusted suppliers made the project a little sweeter in a time that was so unknown for the building industry.

“Box & Co is extremely happy to say that we were able source 93 per cent of construction materials from South East Queensland, with more than 90 per cent of the total employees working on this project living in South East Queensland.

“That not only includes the Box & Co team, but also subcontractors working on various aspects of the works," Mr Box said.

As Brisbane Airport looks to recovery, the newly replaced skylight at the Domestic Terminal will be sure to give passengers a warm welcome to the Sunshine State.

CONSTRUCTION’S C OPPORTUNITY FOR R

by Jon Davies, Chief Executive Officer, Australian Constructors Association

With great optimism, I anticipate 2021 will be the year that marks the turning point in the quest for a more sustainable construction industry. We have a unique opportunity to achieve real and lasting reform, but it will require the support of the entire sector.

G

of the most pressing problems facing the industry, we then developed a framework for a more sustainable sector, followed by an industry charter comprising ten commitments to reform embraced by Australia’s leading construction and infrastructure contracting companies.

Amongst other things, we identified that a sustainable construction industry is one built on the three key pillars of: equitable and aligned commercial frameworks; a strong positive culture; and the capability, capacity and skills to execute the projects it is called upon to deliver.

overnments are relying heavily on the construction industry to lead the economy out of recession, but our industry is sick. Profitability is at an alltime low and productivity growth over the last 30 years trails that of other significant industries by 25 per cent. Women make up only 12 per cent of the construction workforce, and construction workers are six times more likely to die from suicide than a workplace incident.

There is a broad consensus that this sustainability crisis must be addressed for the construction industry to deliver the planned pipeline of projects efficiently, with the resources available, whilst leveraging opportunities to increase training, local procurement and engagement of indigenous and social enterprise.

In late-2020, the ACA published a series of documents that charted a clear way forward. Starting with an analysis

INDUSTRY INSIGHTS to save time and effort developing new contracts or amending existing forms. The best example of which is the NEC suite of contracts from the UK.

POSITIVE INDUSTRY CULTURE While there have been some improvements to industry culture in recent times, construction workplaces and behaviours need to take a quantum leap if we are to make our industry a more resilient and attractive sector to work in, particularly for women.

The Construction Industry Culture Taskforce will shortly start consultation on a draft Culture Standard that seeks to align all parts of industry on the requirements necessary to make this leap.

COVID-19 REFORM All three pillars are interlinked, and therefore improvement in one requires improvement in all. As an example, it is widely understood that adversarial commercial frameworks negatively impact culture, and a positive industry culture is a key factor in attracting people into the industry.

EQUITABLE AND ALIGNED COMMERCIAL FRAMEWORKS Part of the solution to the challenges faced by the industry is greater use of contracts that promote a collaborative industry culture and incentivise innovation. True value can only be achieved when all the parties' interests on a project are aligned, and when open and transparent sharing of information is encouraged.

This is not a call for widespread use of alliance contracts, although the use of alliance contracts to deliver the Level Crossing Removal Program in Melbourne is delivering an exceptional outcome. There will always be instances where the use of lump sum or design and construct contracts are more appropriate. However, there is no reason why these traditional commercial frameworks cannot be drafted to contain more collaborative and equitable provisions, particularly regarding management of project risk.

More collaborative and equitable forms of contracts are in use elsewhere in the world and could easily be adopted here

www.infrastructuremagazine.com.au

SUFFICIENT CAPACITY, CAPABILITY AND SKILLS To avoid capacity and capability constraints in the long term, there needs to be increased collaboration between government and industry to better identify potential skills shortages well in advance. This can be achieved through skills mapping and transparent, accurate project pipeline data.

The data could then be used to smooth resource peaks by amending project start dates or to inform training initiatives to address potential shortfalls.

In the short term, with closed international borders and long lead times to train new people, we need to focus on increasing the efficiency of our procurement and delivery processes.

For example, we should put our valuable resources to work optimising designs and de-risking projects through advance works, rather than tying them up at tender producing volumes of information that add little or no value.

THE OPPORTUNITY If we could just halve the gap in productivity growth that has been created between the construction industry and other industries over the past 30 years, we could construct an extra $10 billion of infrastructure every year for the same level of expenditure! This will be vital in a post-COVID-19 world with high levels of government debt, but no less of a requirement to construct productivity-enhancing infrastructure.

As a starting point, we need more collaborative partnerships between state governments and the private sector to enhance the three pillars supporting the sustainability of the industry.

To fully realise this opportunity, the Federal Government needs to take a more active role in defining and incentivising the use of best practice procurement and delivery processes.

The Construction Playbook, recently published by the British Government, accompanied by a direction to use it or explain why not, is a good example of how this could be done.

In comparison to many other countries, Australia has done a remarkable job in managing COVID-19. In part, this is the outcome of strong collaboration between the public and private sectors. This collaboration is transferable, and it is incumbent upon us all to grasp this unexpected opportunity for change with both hands in order to rebuild trust and develop a more sustainable industry for the benefit of all Australians.

As the industry voice for design, advisory, and engineering businesses in the built and natural environment sectors, Consult Australia has been working with members to build the case for a greater focus on social value in considering infrastructure investments, which we see as critical to Australia’s COVID-19 economic response.

IT’S TIME TO FOCUS ON THE SOCIAL VALUE OF INVESTMENTS

by Nicola Grayson, CEO, and James Robertson, Australia’s Policy Lead (People and Pipeline), Consult Australia

D

espite sometimes being seen as such, the social value from infrastructure investments is not distinct from its economic value. Instead, an increased focus on social value can help shape and inform our investment decisions, ensuring that what we spend our money on results in economic benefits in areas of greatest community need. We see this as a ‘dual-lens’ approach, as a way to align future growth opportunities from investments with the values, objectives and priorities of our communities – the end users of these assets.

To deliver social value from investments and maximise community benefits, we must consider social impacts as early as possible in infrastructure projects – particularly in the business case phase of a project, where we look at whether an investment stacks up.

Social impacts are the consequences, both positive and negative, experienced by people due to changes in their surroundings from a project. While these social impacts can sometimes be difficult to consistently measure, they are no less real for those experiencing them. The earlier we think about them, the more influence we can have on the social value of a project, which in turn can improve the outcomes from a project and ultimately save time and money.

March 2021 // Issue 18

If we spend more time coming up with better ways to fully understand the impacts on how people live and interact, as well as the community’s composition and sense of place during the business case phase of a project, then we have a more complete picture of the ‘problem’ we are seeking to solve through the investment. This will inform whether or not the proposal is the right solution, and importantly, help refine and shape the proposal to align well with community needs.

NEW APPROACHES TO BUSINESS CASES It is also important to note that following this process in itself leads to greater social value because it helps create greater community acceptance and lowers the risk of conflict as the project proceeds through its various stages. Arguably, a failure to follow this process is a significant cause for many projects around the country being cancelled or delayed, rather than a failure in the projects’ merits.

So how can we increase our focus on social value through infrastructure business cases?

Many of our members are developing clever ways to better understand social value by utilising new technology and innovative practices – both from a community-wide perspective and for certain cohorts. www.infrastructuremagazine.com.au

INDUSTRY INSIGHTS

The key lesson we are seeing showcased in these new approaches is the need to move away from a one size fits all approach, or cost-benefit analysis thinking, and instead be more flexible and considerate of the context and objectives.

For example, how we consider the social impacts in a business case for a rail project in a rural area should not be applied to a business case for an arts precinct in an inner urban area. The approach taken must be more tangible and specific to the problem or the opportunity that the business case is looking at.

We have also considered the benefits of bringing forward what happens later in the project to the business case development stage – primarily social impact assessments, which usually happen alongside environmental regulatory approvals once the business case is finalised.

Much can also be learned by looking at some of the practices that sit outside typical ‘infrastructure projects’, such as mining projects, as these have a long history of considering the social value and licence to operate from the community. We believe many of these practices are transferable to infrastructure projects.

www.infrastructuremagazine.com.au

One example is the NSW Department of Planning, Industry and Environment’s Social Impact Assessment Guidelines, which apply to state significant resource projects. Positively, an updated version of this guide is currently being proposed for all state significant projects, including new infrastructure proposals.

COVID-19 AS A CATALYST Consult Australia has published a report looking at this topic in more detail which can be viewed at www.consultaustralia.com.au/home/advocacy/pipeline.

We hope that the report adds to the growing public debate about how we can extract more social value from infrastructure investments. We believe Australia’s economic response to COVID-19 is the catalyst to improve how we assess the investments that are important to us as users of infrastructure, and the legacy that we would like to create for future generations. As such, improving how we consider and shape social value from investments is essential.

SIGNALLING, TRACKING AND CONTROL SYSTEMS

DEVELOPING A NEW TRAIN MANAGEMENT SYSTEM by the Australian Rail Track Corporation Network (ARTC)

Advanced Train Management System (ATMS) is a modern, communications-based, safe-working system for the ARTC, which has been custom engineered for Australian conditions by ARTC and technology partner Lockheed Martin. It enhances the operation of the national interstate rail network, and provides a quantum leap forward in safety, capacity and productivity for freight rail operations.

A

TMS replaces traditional trackside signalling equipment and implements intelligent software technology that allows information to be directly shared digitally between ARTC’s Network Control Centre and a train-borne unit on board a locomotive via mobile telecommunications.

THE EVOLUTION OF ATMS After more than a decade of intense development, testing and design – a cutting-edge train management system has gone ‘live’ in South Australia.

The Advanced Train Management System (ATMS) has completed its final commissioning trials into service and is now the train control system for ‘live’ train services between Port Augusta and Whyalla in South Australia.

The system also has larger ramifications for the national rail network as it will eventually be rolled out nationwide, with work on the next phase along 1,700km of track between Port Augusta and Kalgoorlie already underway.

The Federal Government’s showpiece freight rail infrastructure project – the Inland Rail between Melbourne and Brisbane – will also be ATMS-ready when each section begins operation.

Recently-appointed Australian Rail Track Corporation (ARTC) Chief Executive Officer, Mark Campbell, said this is an important step in the process of upgrading the national network with proven technology that boosts safety, capacity, reliability and enhances the customer experience.

38

March 2021 // Issue 18

“The Interstate Rail Network is the backbone of our freight system and it’s crucial we have the latest systems and technology available to serve our customers well into the future, especially with the Inland Rail coming online,” Mr Campbell said.

“This will revolutionise the way we manage rail freight services by increasing capacity and improving operational flexibility, safety and reliability.

“ARTC is extremely proud of ATMS which has been ten-years in development. This product has been Australian made to benefit the people of Australia.

“This system has been developed from the ground up for Australian conditions. It has been tested under Australian conditions on the South Australian network. It has undergone rigorous testing before we brought the system into operation in August and it has passed every test.”

MOVING FREIGHT FROM ROAD TO RAIL Mr Campbell said further benefits and applications will continue to be incorporated as the ATMS is rolled out to new areas.

“Benefits for our customers will continue to flow as we continue to integrate new features such as fuel and energy management systems, as well as better timetabling of trains through the increases of capacity on the network that ATMS will enable,” he said.

“ARTC has ensured that industry has been at the forefront of consultation during the development of ATMS and we

SIGNALLING, TRACKING AND CONTROL SYSTEMS will continue to ensure that this system delivers substantial benefits to our customers.

“Moving more freight from road to rail will benefit the nation as our freight task continues to escalate. To be the mode of choice, rail needs to introduce cutting-edge technologies.

ATMS is a key step in that objective.”

“The rail freight industry and the Federal Government are working closely together to explore the opportunities to accelerate ATMS implementation across the interstate rail network,” Mr Campbell said.

“This is being done through the Freight on Rail Group (FORG) which is reporting on progress to the Deputy Prime Minister, Michael McCormack.

“Rail is an essential part of the freight supply chain and the COVID-19 pandemic has shown just how much we rely on our rail network to support vital domestic trade and manufacturing supply chains.

“With freight demand set to increase, shifting long-haul freight from road to rail is a strategic priority and part of the Australian Government’s broader agenda for a resilient, efficient and sustainable national freight and supply chain network.

“The operation of ATMS marks a leap forward in train control, not only in Australia, but for the rail freight industry worldwide.”

HARNESSING DIGITAL TECHNOLOGIES The Australian Government has invested $50 million into the development of the system alongside investment from ARTC and Lockheed Martin.

“While rail already has an impressive safety record, ATMS harnesses digital technologies to reduce risk across the rail network even further,” Mr Campbell said.

ATMS is capable of automatically applying the train's brakes where an overspeed has occurred and when predicting the train will exceed its end of authority should a train fail to take appropriate action for the conditions at hand.

For example, ATMS can enforce a train to a stop before it passes an end of authority displaying a stop indication, or before diverging on a switch which is improperly lined, thereby averting a potential collision.

“This system has an automatic safety intervention which provides the ability to apply a train’s brakes which prevents a train from exceeding the section of track it has permission to operate within,” Mr Campbell said.

“ATMS will prevent a range of potential issues The ATMS system simplifies and streamlines the processes for ARTC’s Network Control Centre and reduces the risk of human error. such as train-to-train collisions, overspeed derailments and authorised incursions into an established work zone.

CONDITION MONITORING AND MAINTENANCE

PREPARING ASSETS FOR WHATEVER

THE SUMMER BRINGS

Victorian electricity distributor United Energy (UE) worked right through Melbourne’s COVID restrictions in 2020 to keep electricity supplies safe and reliable for its customers, but it was also preparing for summer, which usually sees more extreme conditions impact the network and put a strain on power systems.

T

he distributor rolled out a $185 million program of works to ensure the network was better prepared for this summer than ever before to support its customers, which are in Melbourne’s eastern and south eastern suburbs, as well as on the Mornington Peninsula.

United Energy General Manager, Electricity Networks, Mark Clarke, said heatwaves, high winds and wet weather could all cause power outages over summer, noting several storm events over the last few months of 2020.

“Our crews worked year-round to make sure our network is reliable, but we recommend everyone has a plan to have the power they need over summer,” Mr Clarke said.

United Energy and its resource partners undertook more than one million work-hours to ensure all network inspection, maintenance and testing was complete ahead of the annual bushfire season.

The highlights of this work include upgrading 47 local substations, (including eight in hazardous bushfire risk areas), installing 2.9kms of covered conductor to insulate powerlines – with another 2.2km to be constructed over coming months – and 91 network spreaders to prevent clashing.

Three Rapid Earth Fault Current Limiter (REFCL) devices were also installed to act as a network safety switch to reduce

40

March 2021 // Issue 18

the risk of fires starting from electrical assets in high bushfire risk areas. These devices are active in Dromana, Frankston South and Mornington, and protect 680km of powerlines servicing 63,500 customers.

The annual, extensive vegetation inspection and cutting program also completed 100 per cent of inspections in high risk areas, with vegetation cut back from tens of thousands of powerline spans.

Mr Clarke said the extensive efforts created greater capacity to deal with peak summer demand, while keeping the network safe and reliable.

“What we’ve also seen is that while customers were working or studying from home, they have become more conscious about their reliance on electricity,” he said.

“Our customers use more power in summer than any other season, so we recommend they know what they need to do if the power goes out for any reason.”

COVERED CONDUCTOR One of the key upgrades United Energy made this summer was a $1.7 million roll out of new technology on the Mornington Peninsula to reduce the risk of fires and outages.

www.infrastructuremagazine.com.au

CONDITION MONITORING AND MAINTENANCE United Energy replaced 5.1km of high-voltage powerlines with covered conductor across the Mornington Peninsula, with 2.9km completed before Christmas and another 2.1km delivered by February.

Covered conductor is a technology that covers long lengths of powerlines and acts like insulted sleeves.

They are being rolled out in targeted high bushfire risk areas across the network where powerlines can also be affected by extreme weather like strong winds, salt spray, moisture or frost.

By protecting powerlines, the covers also help reduce the likelihood of faults and fires.

The areas chosen for the rollout are based on bushfire risk and the number of previous outages in the area, and follow United Energy’s successful trial of covered conductors in Cape Schanck in recent years.

Project Manager, Rob Doyle, said the covered conductor works were part of a broader five-year program to roll out the technology across high risk areas.

“We’re progressively replacing the most vulnerable highvoltage wires with this technology across our network to increase reliability and to decrease the risk of fires starting,” Mr Doyle said.

“This means the network is much better protected if an object such as a tree branch or an animal happens to comes into contact with powerlines.”

The roll out included installations at Merricks North, Somerville, Red Hill and Hastings.

UNDERGROUNDING WORKS Meanwhile, specialist crews moved almost 600m of highvoltage lines underground along Valley Views Lane in Main Ridge on the Mornington Peninsula ahead of summer.

At the site, there were at least 55 large pine trees located on the side of a slope that had been leaning towards powerlines, posing a risk of starting a fire or causing a power outage if a nearby tree or limb fell.

www.infrastructuremagazine.com.au

Mr Doyle said undergrounding the powerlines had reduced the risk of fires starting from electrical assets as well as minimising unplanned outages in the future.

“This line is located on the north west face of the slope, meaning any potential fire start would move quickly given the hot summer winds which normally come in from that direction,” Mr Doyle said.

In early 2020, one of the large trees fell onto the powerlines, affecting power to customers for 12 hours.

Mr Doyle said undergrounding powerlines was just one way United Energy was improving safety in the Mornington Peninsula.

“The Peninsula is a high-risk area for fires and throughout the year we have continued conducting critical maintenance and major projects to ensure the network is ready for summer,” he said.

ADVICE FOR CUSTOMERS No matter the preparation a network does, there are likely to be extreme conditions each summer that leads to outages.

A checklist for customers on how to prepare for summer power outages is available at www.unitedenergy.com.au and includes advice on: 1. Looking after your health – particularly if you rely on life support equipment 2. Staying connected – by having mobile phones and laptop computers charged to stay connected with family and friends 3. Pre-cooling your home – if a power outage is planned as part of ongoing maintenance activities on the network 4. Having backup energy ready – like batteries, lamps and barbeques 5. Staying up to date – by downloading the VicEmergency app and signing up for United Energy SMS notifications about power supplies

CONDITION MONITORING AND MAINTENANCE

WHAT IS A DIGITAL TWIN?

by Imogen Hartmann, Journalist, Infrastructure magazine

The last few years have seen digital twins explode in popularity due to the significant benefits around cost-effectiveness and accuracy, and the ability to identify problems before they occur. They are allowing for more informed decision-making, which keeps project costs from soaring and avoids unnecessary delays – issues infrastructure professionals are constantly facing, especially now with the industry’s key role in the post-COVID economic recovery. Here, Infrastructure explores the technology and its impact on construction operations and maintenance.

T

he concept of a digital twin refers to a digital model of a physical object, process or system. In order to make the model identical, or a “twin” to the reallife subject, the digital model utilises historical and real-time sensor data.

The originators of the term, Dr Michael Grieves and John Vickers, said that a digital twin is “based on the idea that a digital informational construct about a virtual or a physical system could be created as an entity on its own. This digital information would be a 'twin' of the information that was embedded within the virtual or physical system itself and be linked with that system through the entire lifecycle of the system”.

The ability for a digital twin to be able to mirror the developments and changes

42

March 2021 // Issue 18

in an asset is an important function for the infrastructure industry, as it allows for the use of the technology throughout all phases of an asset’s development, including the planning, construction, operation and maintenance stages.

By replicating the physical world in the virtual world, data can be analysed and systems can be monitored to prevent problems before they occur. This allows for infrastructure companies to potentially save costs by using the twin to troubleshoot any issues before the asset is built, and avoid wasting resources, labour and time that would have otherwise been spent fixing a problem.

OPPORTUNITIES AND RISKS Digital twins offer several benefits, such as the ability to provide a safe

virtual environment where users can simulate and test the impact of changes to assets, products, systems and processes based on real-time data.

Benefits to the infrastructure industry include: ♦ Monitoring of an asset in real time ♦ Virtual scenario modelling and testing ♦ Supporting informed planning decisions, detecting and troubleshooting issues ♦ Providing more accurate predictions of potential problems ♦ Measuring performance and efficiencies of assets and equipment ♦ Information sharing with citizens and businesses

www.infrastructuremagazine.com.au

CONDITION MONITORING AND MAINTENANCE Although the technology is developing quickly, there are still some challenges to overcome. Potential risks of using digital twins include: ♦ The type and quality of data that is shared between the asset and the digital twin may mean that the latter is less accurate ♦ Potential challenges in the digital twin’s functionality with existing assets, products, systems and processes ♦ Digital twins with long lifecycles (such as buildings and infrastructure) may outlast the short lifecycles of data formats.

Design software formats have a high risk of becoming unreadable by modern systems at some point in their service life ♦ Potential disputes over ownership of the data being input into, and contained in, the twin ♦ Due to the high level of complexity, digital twins may be expensive to design and create

IMPLEMENTATION IN INFRASTRUCTURE The creation of a digital twin often requires a specialist, such as an expert in data science or mathematics that can identify the physics underpinning the physical object, so that the data can then be used to develop a virtual simulation of the original.

Sensors are then integrated into the original asset to gather data about its real-time status, working condition, or position, all of which is then input into the twin. This is achieved through a cloud-based system that receives and processes all the data the sensors monitor. Throughout this process, the twin is able to simulate the physical object in real time, whilst offering insights into performance and potential problems.

To use an example, a factory might employ digital twin technology to measure the effectiveness of its systems and machinery. This would first require the use of historical data to replicate the factory in a digital simulation. Then, the sensors would be able to feed in real-time data to the digital twin user, allowing them to remotely assess the factory activities as they’re occuring.

In other cases, a prototype of an asset (such as a building, railway, or water pipe) can be used before the end product is built, allowing the technology to provide feedback as the end product is refined. In the absence of a physical asset, the twin itself can also act as a www.infrastructuremagazine.com.au

prototype. For example, a digital twin of a building before it is built can allow the designers, architects and engineers to identify any potential problems or opportunities for improvement before construction commences.

Digital twin technology has the capability to process complex data and systems, but it can also be simplified depending on the level of data used to construct and update it. For example, a digital twin of a road junction or traffic light might require more complex data in order for the user to monitor peak times, types of vehicles passing through, weather conditions and safety hazards.

However, a simpler digital twin might be beneficial for an energy company that operates a wind farm if it wants to optimise operations but is struggling because of the unpredictability of the weather. A digital twin could use historical data from a certain period of time to see how much energy was generated and in what conditions, then use this to predict the ideal angles for the wind turbines, as well as monitor wear and tear to forecast the lifespan of the assets.

ACHIEVING A NEW SCOPE OF MAINTENANCE Digital twin technology not only helps to inform decision-making in planning and construction phases, but it can also support companies in maintenance and condition monitoring. If an issue arises in an asset that the asset manager isn’t sure how to fix, technicians can use digital twins to test solutions before applying them to the physical twin, allowing them to ensure safety and effectiveness.

The live data feed provided by the sensors also allows the digital twin to monitor the condition of an asset for issues in real time. This live condition monitoring means digital twins can be used for predictive maintenance, where faulty components or assets at the end of their useful life can be replaced prior to an issue arising. This process also eliminates the need for some manual inspection, and increases safety by allowing the operator or owner to proactively identify and remedy potential problems before they occur.

One example of digital twins being utilised for maintenance and condition monitoring is a project by Victorian Power Networks (VPN) and United Energy (UE) which saw the development of a digital twin using LiDAR data to help with vegetation management of their electricity infrastructure.

VPN and UE own and operate large electricity distribution networks, totalling over 850,000 poles and more than 800,000km of powerline. The energy networks are also responsible for complying with strict regulations, requiring innovative and cost-effective safety solutions for maintaining network infrastructure.

To do this, the companies launched a LiDAR Lab to use digital twin technology as a surveillance method, measuring the distance to a target by illuminating the target with a pulsed laser light, and measuring the reflected pulses with a sensor, to create a digital model of the terrain.

The digital mapping allowed the networks to measure the distance between vegetation and powerlines to within 10cm. As vegetation-topowerline proximity poses significant bushfire risks, the ability to closely monitor these distances affords the networks an important level of infrastructure safety.

It then used LiDAR to develop a digital twin of the entire network for asset management-related activities, such as determining the clearance between the conductors and the ground – a process that is currently done manually.

FUTURE-BOUND ASSET MANAGEMENT Despite some potential challenges, digital twins are being dubbed by experts as one of the most imperative strategic technologies for businesses and governments, particularly within construction and asset management.

Dr Samad Sepasgozar from UNSW Built Environment said the digital twin is “not a pipedream, but the next frontier of construction management”.

“At the strategic level, the digital twin is a new game-changing approach to construction automation … that will transform the industry quicker than ever before,” Dr Sepasgozar said.

Digital twins have already been adopted by factories and manufacturing industries, automotive companies, aerospace engineers, local governments and councils, as well as the utility, energy and healthcare industries.

Digital twins are expected to unlock new collaboration opportunities among physical world product experts and data scientists in the future, as well as enhancing customer experiences and improving products, operations and services.

INFRASTRUCTURE-BASED SENSOR TECHNOLOGY FOR "COOPERATIVE AWARENESS" PROJECTS As part of V2X (C-ITS) projects, or when preparing roads for autonomous vehicles, it is necessary to gather data on all road users (cyclists, pedestrians, etc.) in the transport infrastructure.

S

ICK Sensor Intelligence offers a uniquely broad portfolio of 2D and 3D LiDAR sensors for this purpose that are suitable for harsh outdoor applications. The outdoorScan3 safety laser sensor is the world’s first 2D LiDAR safety sensor to be approved for outdoor environments and is certified in accordance with ISO 13849-1 and standard IEC 62998.

The outdoorScan3 safety laser scanner is designed to allow man and machine to work safely side by side, and thanks to its patented safeHDDM® technology and intelligent algorithms, disruptive weather influences such as rain, snow, sunlight and fog are filtered out with ease. As a result, it offers limitless potential for increasing business productivity and efficiency, both indoors and outdoors.

INCREASING SAFETY ON CONSTRUCTION SITES From basic safety mat replacement and presence detection, through to protecting multiple hazardous areas at the same time, the outdoorScan3

is the ideal choice. Suitable horizontal protective fields can be set up and monitored to protect against the dangers posed by hazardous machines, plants or open spaces.

Radar technology-based sensors from SICK can also be used for similar applications. The MRS1000 multi-layer 3D LiDAR sensor detects and measures objects in multiple dimensions. By collecting large volumes of data on multiple scan layers and from different angles, it can detect and respond to objects on the floor as well as objects that are obstructing the path.

On construction sites, excavators often collide with objects while maneuvering or reversing due to reduced visibility around the rear of the vehicle. The driver assistance system’s sensors must be able to classify objects and their relevance to the collision warning system. The MRS1000 3D LiDAR sensor features an IP67 enclosure and detects up to 55,000 measuring points across four layers, enabling it to recognise objects standing on the floor or located in the vehicle’s travel path in plenty of time. Cutting-edge HDDM+ technology with multi-echo evaluation guarantees precise measurements, regardless of the weather conditions.

AIRPORT AUTOMATION High personnel and operational costs necessitate a higher degree of automation in airports, for example, through the automated docking and

undocking of passenger boarding bridges. With the outdoorScan3, fast and smooth connection and disconnection can be achieved under extreme weather conditions on the runway. The safety laser scanner also ensures the safety of people in the vicinity whenever the boarding bridge drive unit is moving.

DATA ACQUISITION FOR TRANSPORT APPLICATIONS Modern traffic management on road, rail and sea routes is geared towards safety, efficiency and a good environmental balance. Rugged sensor solutions provide reliable control and monitoring systems for transportation applications. With solutions from SICK, you rely on many years of experience indoors and outdoors.

Laser measurement systems classify vehicles as part of the road toll system, automation light grids reliably detect people at train door systems, and dust measuring devices and gas analysers measure pollutant concentrations in tunnel areas.

The wide range of rugged and innovative products combined with a worldwide service and sales structure has made SICK a market and technology leader in many fields of data acquisition in traffic engineering.

O

ver the last 20 to 30 years, airport operations remained largely unchanged – largely reliant on segregated technology systems and manual processes managed by in-person interaction. This has made it harder to respond to changing resource needs and increased strain during peak periods.

In recent years, small evolutionary changes to improve and simplify passenger flow through a terminal have started to become standard practice. Self-service check-in and baggage drops at automated kiosks are commonplace. More recently, upgrades to security and passenger screening queueing ahead of departure are becoming more common and upon arrival in Australia, e-gates for immigration are a welcome change.

As we are designing Western Sydney International (Nancy-Bird Walton) Airport, we’re thinking beyond these discrete systems upgrades and considering how tomorrow’s technology will come together with great design and customer service to create a stress-free experience for our customers.

building utilities to aircraft apron management, and customer information to freight management. In a smart airport, these systems must communicate and work together effectively from your front door to the aerobridge.

A 2019 survey of more than 1,000 Brits found that the single most stressful part of air travel was getting to the airport (63 per cent), followed by baggage collection (49 per cent), and passing through security and waiting for transfers (47 per cent).

Australian airports are prone to the same concerns. We all know the delight of the captain’s announcement upon landing that you are ten minutes ahead of schedule, only to discover there is no operator available to connect the aerobridge to the aircraft. The desperation of the connecting flight dash between terminals, only to discover the flight has moved gates. These situations are frustrating and unnecessary. That’s why we are putting ourselves in our passengers’ shoes, and taking advantage of the latest technology, so we can build the best airport possible.

GLOBAL CHALLENGES OF AIR TRAVEL From the moment passengers arrive, through check-in, security and immigration to the boarding gate, we want every stage to be fast and easy.

Throughout an airport, there are more than 100 technology systems, ranging from baggage handling to airside access,

AN INTEGRATED TRANSPORT JOURNEY Western Sydney Airport is focused on designing and delivering a fit-for-purpose airport, digitally enabled at the terminal, for our passengers and airline customers.

Upon arrival, your bag would be returned to you with precision, or could be easily transported to the office, your home or hotel for your convenience on a dedicated service.

On the landside, we are closely collaborating with Transport for NSW, Sydney Metro, Australian federal law enforcement agencies, the Department of Agriculture and a range of other organisations to deliver tightly integrated transport and logistical access for both customers and cargo.

Two new Sydney Metro train stations at the Airport Terminal and Airport Business Park, and integration with the new M12 motorway into and out of the airport precinct, will ensure passenger and freight arrival alike will be fast, more accurate and reliable from kerbside to the plane, safely, seamlessly and stress free.

While we are still early in the design journey, safety, privacy and security is front of mind. The requirements of running a smart and modern airport in a heavily regulated industry are complex. Compliance with federal and state legislation is necessary, and while there’s a lot of work ahead, our team

is committed to delivering the people of Western Sydney a game-changing airport that we can all be proud of.

PREPARING FOR A POST-COVID REALITY A smart airport for passengers and their families means a better passenger journey, a consistent service, real-time information and getting you where you need to go safely. For airlines, efficient and smooth turnaround of aircraft is crucial to maximise asset usage, build profitable routes and demonstrate value for money.

According to IATA’s 20-year global forecast, while the aviation industry is resetting in a post COVID-19 reality, there will be 2.8 billion more passengers per year by 2039. Opening in 2026, Western Sydney International stands ready as the full-service airport of choice for international, ultra-long haul and domestic travel on full-service airlines and low-cost carriers.

Within 20 years, one in two Sydneysiders will call Western Sydney home, and demand for passenger journeys in the Sydney region alone will more than double from 40 to 87 million. Coupled with the power of technology to deliver a seamless, stress free travel experience – Western Sydney International will be the smart choice.

n order to keep up with increasing demand, Australia’s construction industry can no longer rely on labour intensive 2D methods to support construction, as they run the risk of creating unnecessary design transactions, or can lack the information consistency needed on projects.

Virtual twins and 3D modelling on the other hand can improve manufacturing and construction efficiency and speed up processes. A virtual simulation of a construction project can identify any potential issues or risks companies might face in the field. These risks can be fixed or mitigated before construction begins, avoiding costly delays. 3D processes can be used in every step of a project’s lifecycle; from design and construction, through to operations and maintenance.

In the recent series of webinars Smart Construction Rendez-vous, run by global leader in 3D design and engineering software Dassault Systèmes, Global Strategic Business Development Director, Prashanth Mysore, outlined the construction simulation technologies that can help accelerate projects, increase construction predictability and improve long-term value for project owners as well as profitability for project contributors.

“Our experience says that 80-85 per cent of project challenges occur in the execution/construction side, compared to 10-15 per cent during planning, so there is an opportunity for construction companies to take advantage of the benefits of emerging technologies like smart construction,” Mr Mysore said.

PARTNER SOLUTIONS // SOFTWARE, COMMUNICATIONS AND CONNECTIVITY “It is expected there will be a wider use of technology in construction and construction management in the future, as companies realise the long-term benefits on productivity, efficiency and cost savings.”

SMART CONSTRUCTION AND SIMULATION TECHNOLOGIES ACCELERATING PROJECTS Building information modelling (BIM) BIM creates a digital prototype of an actual building or asset before it’s built. This enables the consolidation of information relating to the design, simulation, project management and construction functionality. All stakeholders – designers, contractors, suppliers etc. – can access the latest update of the project in 3D, allowing for faster decision-making between all participants collaborating on a single project.

Virtual twin experience for construction monitoring Dassault Systèmes’ 3DEXPERIENCE platform is essentially a unified digital cockpit that monitors construction execution so companies can make informed decisions. It can connect and collect data from machines, equipment and facilities on construction sites, enabling managers to dramatically improve construction performance by accelerating identification of errors and subsequently fixing errors using collected real-time data.

It is a true virtual twin experience model, monitoring live and capturing data that can be used later in operations and maintenance phases. The platform is a lifecycle management system so it not only includes 3D models, but also the project information, simulations and all of the project data in one single source.

Modular construction with 5D Modular construction is best practice for the manufacturing industry and involves constructing sections off-site then delivering to the location. The 5D methodology for modular construction is essentially an integrated simulation of 3D plus time plus cost. It involves the simultaneous process of creating models

while the site work is occurring, with the basis of prefabricated construction being the initial design in 3D. BIM is also used to ensure suitability of the location and the design requirements. Modular construction allows developers and contractors to deliver shorter timelines with less risk, with techniques reducing the length of construction schedule by up to 50 per cent.

3D printing/additive manufacturing 3D printing, also known as additive manufacturing, is currently gaining traction in the industry as it allows you to create construction components or modular parts of buildings. Construction is well suited for 3D printing as the information needed to create a part already exists in the 3D BIM design.

It allows for faster and more accurate construction of complex or bespoke items, lowering labour costs and producing less waste.

Big data and predictive analytics Big data can support fast, accurate decision-making from multiple data sources in real time, making construction sites smarter and improving productivity.

For example, when it comes to maintenance and operations, 3D contextualisation of IoT data can help identify specific issues on-site.

Using in-built machine learning algorithms, data scientists can identify a piece of equipment that is causing a maintenance issue. The maintenance log inside Dassault Systèmes’ 3DEXPERIENCE platform helps to identify particular equipment that is causing production stoppages, with the data able to be compared with sensor and historical data. With in-built machine learning and AI algorithms, companies can pre-emptively identify issues with various equipment within maintenance and operations phases.

Augmented reality and VR Mr Mysore said for an industry that has been notoriously slow to accept technology changes, construction is actually an early adopter of two of the most advanced technologies in existence – augmented reality (AR) and

virtual reality (VR). These technologies can visualise blueprints, maximise efficiency and improve workplace health and safety.

VR is used by developers to review real 3D environments of architectural designs. By using a combination of BIM and immersive VR headsets, architects, project managers, civil engineers and the whole project team can identify design flaws and better plan construction projects before they begin.

AR is used by project managers on-site to ensure a structure is being built exactly as the design intended, rather than just using line of sight to confirm.

This significantly speeds up projects and minimises errors.

Autonomous construction Autonomous construction is the use of advanced robotics to replace or improve existing processes, making them more efficient and accurate. Mr Mysore said robotics aren’t playing a huge role in construction right now but this will soon change, so companies should get on board early. With the industry facing increasing pressure to construct quickly and in a more reliable and safer way, this is where robots can be useful.

IIoT and execution monitoring IoT plays an important role as it can connect sites, enhance safety, reduce accidents and improve work processes.

Sensors connected to the internet can continuously monitor and manage critical resources at construction sites such as electrical systems and various mobile resources in real time. IoT is commonly used to monitor machines around the site and track progress of work. Sensors mounted on construction equipment and safety hats worn by construction professionals also help optimise the utilisation of manpower and physical assets.

As illustrated, there are a number of constantly evolving technologies available to construction companies and by using smart and lean construction methods, companies can become more flexible and agile, and better prepared for future disruptions they may face.

INTELLIGENT TRANSPORT SYSTEMS:

A REVOLUTION ON OUR ROADS

by Michelle Goldsmith, Journalist, Infrastructure magazine

Across Australia and around the globe, Intelligent Transport Systems (ITS) are already making road travel safer, more efficient and more sustainable. Such systems are only becoming more and more relevant as population grows and the number of vehicles on the roads increases, with various ITS technologies offering solutions to decrease congestion, increase efficiency and mobility, and even save lives.

F

undamentally, ITS involve integrating information and communication technologies into transport systems to optimise operations. ITS encompass a broad range of systems and technologies, with varying levels of complexity and automation. While smart systems can be applied to any form of transport, the term ITS is most frequently used in reference to road transport.

The ‘currency’ of any ITS is its data, which is used to improve the transport system’s operations, often in real time. As such, ITS employ a variety of wired or wireless technologies to collect, transmit, communicate and interpret data, with many also including automated control functions. ITS infrastructure may involve technologies integrated into road networks (e.g. roadside sensors), within the vehicles themselves, or both. Essentially, ITS enhances connections between road users, vehicles, road infrastructure and transport system operators.

ITS solutions are generally applied to do one or more of the following: ♦ Improve the mobility of people or goods ♦ Increase safety ♦ Reduce traffic congestion and increase transport efficiency ♦ Inform road users of conditions ♦ Respond effectively to incidents and emergencies ♦ Increase the resiliency of the transport system in case of changed conditions or unforeseen disruptions ♦ Reduce air pollution or improve energy efficiency ♦ Automate billing processes ♦ Achieve policy objectives (such as demand management or transport priority)

March 2021 // Issue 18

ITS INFRASTRUCTURE IN ACTION ITS fulfill various vital functions on our roads, reaping significant benefits for road users and operators, as well as for our broader society and economy.

Traffic management ITS traffic management is concerned with the overall management of traffic on a road. The ITS detects traffic situations and deploys traffic control strategies. Technology is applied to traffic signalling systems, traffic safety, and route and congestion management.

For example, the busiest roads around Melbourne, including the M80 Ring Road, Tullamarine, West Gate and Monash freeways, Eastlink and Citylink, use coordinated dynamic ramp metering to measure and regulate the number of vehicles entering and exiting in real time. This enables each road to handle the maximum number of vehicles while maintaining traffic flow, reducing travel times and preventing safety issues associated with congestion.

Controlling traffic signals to only allow a certain number of vehicles to merge onto a road at a time helps break up groups of vehicles that might otherwise be competing for space, reducing the likelihood of collisions. Ramp metering signals that become operational during peak times have also been deployed as part of Sydney’s $600 million M4 Smart Motorway project.

Similarly, ITS such as the Sydney Coordinated Adaptive Traffic System (SCATS) employ in-pavement detectors and other sensors at busy intersections to monitor demand for right-of-way and shifts in direction of demand.

Traffic signals then adapt accordingly, resulting in a smoother flow of traffic and minimising wait times. The SCATS Priority Engine also allows essential www.infrastructuremagazine.com.au

vehicles (such as emergency services) to be prioritised through traffic lights.

In Queensland, Hold the Red, an innovative intersection crash avoidance system trialled at four intersections in Brisbane and the Gold Coast, demonstrates the potential of ITS to prevent traffic incidents and enhance safety. The system uses radar to predict when a vehicle approaching the intersection is going to run a red light. When this occurs, the system extends the all-red phases of lights at the intersection by two seconds, preventing other vehicles or pedestrians from entering the intersection where they could collide with the offending vehicle.

Traveller information A common function of ITS technology is to better inform road users about road, environment and traffic conditions.

These services enable road users to plan the most efficient route, avoid delays and quickly become aware of any changed conditions, potential hazards or emergency situations. For instance, signs may display current travel times or advise of incidents or lane closures, or real-time information about conditions might be conveyed via highway advisory radio or reflected in GPS data.

Real-time traffic information signs and variable message signs are employed on a variety of roads around Australia, while certain busy car parks use parking guidance systems to advise of parking availability. For example, the Parramatta Parking Finder helps support people with accessibility issues by providing information about accessible parking spaces around the Parramatta CBD including photos of the space and a rating out of five for the size of the space, hoist suitability and kerb ramp access.

Some of the potential benefits of ITS integrated with connected and semi-autonomous vehicles have been demonstrated by a trial undertaken by the Victorian Department of Transport on Eastlink, which involved the operational deployment of semi-AVs and cooperative intelligent transport systems (C-ITS). The project developed a DSRC messaging platform that delivered real-time road warnings in a high-speed environment, with high reliability and precision (to location and lane), without interfering with the existing tolling system. www.infrastructuremagazine.com.au

Emergency management and response The real-time monitoring capabilities of ITS can greatly reduce emergency response times, saving lives, preventing secondary incidents and reducing disruptions. For instance, if a collision occurs, the relevant authorities are alerted, and the nearest emergency vehicle is located and dispatched to the scene. Other drivers on the road can be alerted through dynamic signage and signals may change to prevent too many vehicles entering the area of the accident until it is safe to do so.

In South Australia, on the section of the North-South Corridor between Torrens Road and River Torrens, a Thermal Video Incident Detection System detects slowing, stopped or wrong direction vehicles within 5-15 seconds, fast-tracking incident response actions. These include notifying drivers of lane closures and congestion using variable message signs and monitoring the situation with CCTV pan-tilt-zoom cameras.

Meanwhile, the Queensland Police Service employs drones and motorcycles to expedite serious crash scene clearance times, allowing traffic managers to estimate the duration and severity of congestion impacts and use existing ITS technologies to help manage congestion and prevent secondary incidents. Using drone technology to map crash scenes, the Forensic Crash Unit has reduced scene mapping time by 50 per cent, reducing road closure times and traffic congestion, while also improving the quality of evidence captured at scenes.

In Brisbane, a structural health monitoring system has been developed to detect damage to the iconic old Sir Leo Hielscher Bridge (the Gateway Bridge) in real time, before it can affect public safety. These are just some of the ways in which ITS are currently transforming Australian road travel, with much more to come.

As the field of ITS continues to develop rapidly, the deployment of smart systems on our roads can help address significant social, economic and environmental issues. With the costs of congestion predicted to rise to as much as $40 billion by 2030, and over a thousand lives still lost on our roads each year, we cannot afford to miss this opportunity to reap significant benefits at a relatively low cost, leveraging data to revolutionise road transport.

The NSW Spatial Digital Twin incorporates the largest 3D modelling project ever undertaken, with the final product including 3,396km2 of seamless 3D mesh captured at under 6cm pixel resolution across the greater Western Sydney region.

Key to this endeavour was Australian 3D modelling expert Aerometrex, who captured and processed the necessary 3D data to underpin the NSW Spatial Digital Twin. It spent several months capturing, processing, and combining the imagery.

project stakeholder uses the same validated source, making duplicate data investments unnecessary. 3D visualisation gives all stakeholders a more tangible and dynamic sense of space. Users can see and understand space and how the change will impact it.

OPEN SOURCE 3D MESH DATA What makes the NSW Spatial Digital Twin so remarkable is its open-source presentation, publicly accessible through a browser-based web portal. That foundational information source brings compounding efficiency benefits as government, private industry, and the general public can all refer to a central and consistent data source.

Victor Dominello, the NSW Customer Service Minister, said the high availability of aggregated data will help with planning future development.

“Using the digital twin, we can model where we put the roads, hospitals, schools, etc. with precision planning like we’ve never done before. This is truly transformational technology and the best thing about it is that it’s open source – industry can use it, councils can use it, everybody can get involved and build this asset together for all of us,” Minister Dominello said.

FINDING THE FAST TRACK FOR RAIL INNOVATION

March 2021 // Issue 18

RAIL EQUIPMENT

by Caroline Wilkie, CEO, Australasian Railway Association

As COVID-19 restrictions hit Australian supply chains, three quarters of rail businesses surveyed by the Australasian Railway Association (ARA) said they were looking to increase their use of local suppliers to support their operations.

T

hat shift in focus was fast and necessary in changing times, but also represented a real opportunity for government and industry to work together to create a new future for rail innovation in Australia.

As one railway technology supplier observed in the development of the ARA’s report Finding the fast track for innovation in the Australasian rail industry, “…machine manufacturing is not going to come back unless we embrace more innovative manufacturing technologies”.

So how do we embrace that innovation focus to make the most of this moment in time, and secure a greater share of the $362 billion rail technology market?

RAIL INNOVATION AROUND THE WORLD The ARA’s report found Australia’s manufacturing strengths leant itself to the production of high value, high technology goods; an area where there is an increasing focus within the rail industry.

The benefits of a rail innovation culture could be significant; improving efficiency, productivity and the customer experience across the rail network – just look at the overseas experience.

In Germany, the adoption of building information modelling (BIM) to reduce energy use and maintenance led to significant cost savings.

On Berlin’s U’Bahn network, the application of ICT tools helped halve wait times.

In the US, preventative maintenance technology such as wayside detectors, smart sensors and infrared lasers have reduced mainline equipment-caused accidents by 36 per cent over a decade.

That is a huge and important contribution to the safety of the network.

www.infrastructuremagazine.com.au

In the UK, the Rail Sector Deal led to investments in data, digitisation and sustainability to deliver up to £31 billion in benefits.

The establishment of the UK Rail Research and Innovation Network (UKRRIN) to bring together industry, government and academia has also provided a step change in innovation and new technologies in the local rail industry.

And that ambitious focus is paying off, with the industry attracting $2 in private sector investment for every dollar in government spending.

AUSTRALIA’S PROGRESS Here in Australia, our record of achievement has not been as significant, with a lack of long-term focus on research and innovation hampering our progress.

But there have still been clear successes in the use of technology and innovative equipment solutions to support better outcomes on the rail network.

One example is VicTrack’s new sensor arrays and use of artificial intelligence to predict adverse car and track conditions.

The technology has improved safety and made it easier to direct maintenance efforts to where they are needed most.

In New South Wales, automation used on the Sydney Metro has boosted cost recovery when compared to the traditional rail network.

And while the common perception is that rail innovation perhaps is far more advanced elsewhere, there are already examples of Australian ingenuity being exported around the world.

The Monash Institute of Rail Technology has firmly established a global reputation for its work. Its condition monitoring technology improves the efficiency, safety and comfort of busy passenger rail lines, while extending the life of rail

infrastructure. So much so that the technology was implemented on the Hong Kong Metro in 2017 to support the delivery of services for 5.4 million people every week.

The question now is how does Australia make the most of the opportunity to gain a greater share of the global rail innovation market.

ADOPTING A CULTURE OF INNOVATION The first step is to make innovation a national priority.

Just as the UK experience has shown, a clear and ambitious vision by government is key to attracting private sector investment in the local innovation market.

That will require a longer-term focus on rail research and innovation funding, with a clearly defined pathway to commercialisation of new concepts developed in Australia.

A national focus on rail innovation will also be required, with a standardised approach to rail policy and procurement an essential part of ensuring the industry can gain the scale it needs to justify the investment in new research and technology.

Finally, we must be willing to adopt a culture of innovation at every level of the rail industry.

That will require industry participants working together to try new approaches that achieve better outcomes. The industry as a whole will also need to plan for digital technologies to continue to be further integrated into the network over time.

If we get these issues right, Australia will not only benefit from a faster, safer, more efficient rail network, but will also be able to export more of its talents to the world.

That is an outcome we should all be striving for.

RAIL TRESPASS PREVENTION – DETECTION AND INTERVENTION

by Garry Taylor, Operations Manager – Australia, Armitage Group

In the moment of rail trespass, what technology exists to provide immediate detection and enable rapid intervention?

C

ertain places and circumstances contribute to rail trespass, where ease of access to a particular location may influence the likelihood of an incursion. Various studies have recommended a focus on limiting access to rail infrastructure, with an elimination approach involving an increase of physical barriers.

However, what can be done in the

precise moment of incursion – that critical time during and just after unauthorised entry?

Technology has evolved to a point where thermal imaging and video detection can be used to provide an automated detection system for rail infrastructure. Deployed in strategic locations, automatic detection cameras can create a network of virtual IT fencing, providing accurate trespass detection and automatic notification, regardless of physical observation, shift changes, time of day, or lighting.

Physical intervention response times will vary depending on availability and response distances, which highlights

the importance of minimising detection and notification times, where the initiation of early warning measures can alert oncoming trains to take preventative action as soon as possible.

The additional integration of a public announcement system to communicate that the area is being monitored could also act as a deterrent and persuade people to leave a place of danger.

In combination, thermal imaging with integrated detection technology is a proven and cost-effective measure in preventing rail trespass, enabling rapid intervention, minimising disruption, and lessening social and economic impacts.

RATCHETING PERFORMANCE OF HIGH STRENGTH RAIL STEELS

by Dr Jerome Pun, Senior Research Engineer, Monash Institute of Railway Technology

Jerome Pun recently won the ARA's Emerging Rail Specialist Award for his work on ratcheting performance, which plays a key role in causing the rolling contact failure of high strength rail steels. Here, he looks at the performance of three high strength rail steels that are currently used in Australian heavy haul railway system and how they behave under different operating conditions.

o help reduce rail degradation i.e. wear and/or rolling contact fatigue associated with the demanding conditions imposed by higher axle loads and increasing annual haulage rates, high strength pearlitic rail steels with carbon contents of 0.8 per cent or higher (eutectoid and hypereutectoid grades) have been commonly used in Australian heavy haul railway networks.

It has been found that the application of high strength rail steels reduces rail wear under heavy haul operating conditions. However, it also influences the relative rates at which wear and rolling contact fatigue damage occur on the railhead. In some cases, the morphology of rolling contact fatigue damage is also altered.

WHAT IS RATCHETING? In the wheel-rail rolling contact process, the rail is subjected to cyclic loading, and the rail surface is subjected to rolling and sliding and relatively high contact stresses. The stresses endured by the rail are always multi-axial, non-proportional and randomly fluctuating in magnitude and direction. It has been found that the cyclic stresses and resulting plastic deformation are the major factors influencing the rail degradation processes.

In cases of wheel-rail contact conditions that result in stress levels above the plastic shakedown limit, also known as the ratcheting threshold of the rail material, new plastic deformation occurs and accumulates under each cycle of loading. This material response under cyclic loading condition is known as ‘ratcheting’.

When the accumulated plastic strain, also known as ratcheting strain, reaches the limiting ductility of the rail, the rail will fail at its local material point, which corresponds to the initiation of wear or rolling contact fatigue, i.e. in the form of head checks (cracks) in the railhead.

RATCHETING PERFORMANCE OF THREE HIGH STRENGTH RAIL STEELS We conducted a comprehensive study, which consisted of both experimental and numerical studies, to investigate the multi-axial ratcheting behaviour and performance of three high strength rail steels currently used in Australian heavy haul railway operations.

The three high strength rail steels included a low alloy heattreated (LAHT) rail grade with carbon content of 0.8 per cent, and two hypereutectoid rail grades with carbon content of 1.0 per cent (HE1) and 0.85 per cent (HE2), respectively.

Our experimental studies revealed that the multi-axial ratcheting behaviour of all three rail steels is significantly influenced by the multi-axial cyclic stress amplitudes and the non-proportional loading path, albeit that all three high strength rail steels exhibit cyclic hardening.

In comparison, the LAHT rail steel shows the best resistance to ratcheting. Among the two hypereutectoid rail steels, the HE1 rail steel, which contains a higher percentage of carbon content, gives a lower ratcheting strain and ratcheting strain rate under high equivalent cyclic stress amplitude.

We also conducted wheel-rail cyclic rolling contact simulations to evaluate the ratcheting performance in terms of crack initiation life of these three rail steels under different heavy haul operating conditions.

The analysis shows that under relatively mild operating conditions – low creepage, low friction levels and lower axle load (≤ 35 tonnes) – the LAHT rail steel has the best resistance to ratcheting and performance (the longest crack initiation life). However, under high creepage and high axle load (> 35 tonnes) conditions, this rail steel shows the worst

62

March 2021 // Issue 18

performance compared to the other two hypereutectoid rail steels, indicating that the LAHT rail steel may not be suitable for harsh operating conditions.

For the other two rail steels, the HE1 rail steel shows a relatively worse performance compared to the HE2 rail steel under all considered operating conditions, albeit that the ratcheting strain rate endured by HE1 rail steel may be lower in some situations. This is attributed to the lower ductility limit of the HE1 rail steel, which is about 68 per cent less than the HE2 rail steel.

Microstructural analysis also revealed that pro-eutectoid cementite is observed in the prior-austenite grain boundaries in the HE1 rail steel primarily due to its high carbon content. The presence of pro-eutectoid cementite is undesirable as it is a source of embrittlement and hence, reduces the rolling contact fatigue resistance of the rail steel. This finding suggests that the use of high strength rail steels with high-end carbon content i.e. the HE1 rail steel, could potentially require more frequent maintenance due to the reduced ductility limit and hence, increased likelihood of rolling contact fatigue development.

Of the three considered rail steels, the HE2 rail steel appears to have the most consistent resistance to ratcheting and performance under all considered wheel-rail rolling contact conditions. Therefore, the HE2 steel is deemed to be more suitable to fulfil the demanding conditions in heavy haul railways among all three rail steels. The results obtained from our analysis are generally in line with the in-service performance of these three high strength rail steels under heavy haul conditions.

APPLICATION AND MAINTENANCE OF HIGH STRENGTH RAIL STEELS The in-service performance of a rail steel is directly affected by both operating conditions and the effectiveness of maintenance strategies. Based on our findings, the selection of suitable rail steels for a specific network, or even for a specific track section, should take into consideration the influence of the given operating conditions on the actual performance in terms of both wear and rolling contact fatigue of the rail steels. In addition, other considerations, such as weldability, should also be given at the time of selection of high strength rail steels.

Although the increased hardness of high strength rail steels improves the resistance to wear and deformation, it is still essential to undertake ongoing cyclic grinding at the appropriately designed intervals. The grinding activities should aim not only to rectify the rail profile to the target profile but also clean up existing rail surface defects.

It is also important to note that wear and the likelihood of rolling contact fatigue could be increased for poorly profiled rail sections such as the presence of peak or undercut in the railhead. Therefore, grinding activities should target to achieve good conformance to the target rail profile.

Appropriate selection and application of rail steels in accordance with the given operating conditions together with an effective and high-quality rail maintenance regime are expected to enhance the advantages of using high strength rail steels and extend the rail life.

hat role does the quality of compaction in road construction have on delivering a longlasting, high performing pavement? The industry knows just how vital the compaction process is to achieve the best outcome. Many local and state governments are becoming increasingly concerned with costly repairs and maintenance that can occur later down the road due to poorly compacted pavements.

Intelligent Compaction technology has the potential to significantly reduce construction and maintenance costs by optimising the compaction process through improved uniformity and consistency of materials. It brings with it realtime feedback and monitors to assist the roller operator, using a system of hardware, software and analysis equipment.

Although Intelligent Compaction technology is quite new to Australia, it has a proven track record overseas, where it was first developed in Europe and has been increasingly used throughout Asia and the United States. As part of the NACOE program, a research project commenced in January 2019 intending to assess the suitability of implementing Intelligent Compaction for quality control in future road construction.

WHAT ARE THE BENEFITS OF USING INTELLIGENT COMPACTION? Through researching international best practice and field testing the technology in Queensland, Intelligent Compaction is displaying benefits in the following areas: ♦ Real-time operator feedback enabling continuous placement of material (without delays of traditional test methods) ♦ Identify weak areas on pre-mapping of underlying layers ♦ Optimise rolling pattern (coverage and speeds) ♦ Allows for 100 per cent of compacted area to be assessed, avoiding under/over compaction of isolated areas ♦ Capturing and securely storing the compaction process information as permanent georeferenced records ♦ Improved uniformity of earthworks and pavements, which is expected to lead to significant improvements in service life ♦ Reduction in greenhouse gas emissions due to more efficient construction practices and reduced maintenance

INTELLIGENT COMPACTION DATA MANAGEMENT WORKSHOP IN QUEENSLAND The NACOE research on Intelligent Compaction implementation is led by Dr Jeffrey Lee, who delivered the first-ever twoday Intelligent Compaction Data Management (ICDM) workshop in Queensland in 2019, alongside Dr George Chang.

The first day of the event covered the basics of Intelligent Compaction, which gave participants a hands-on experience of using the Veta software. On the second day, a field demonstration was conducted using a Dynapac smooth drum roller with a Trimble IC retrofit kit at a test strip, where the Intelligent Compaction roller was used to compact a general fill area (60m by 23m) on test strips using three different moisture contents.

PSTS116 was initially developed to undertake a compaction audit using an Intelligent Compaction roller on the Ipswich Motorway Upgrade: Rocklea to Darra – Stage 1 (R2D) project between March and October 2020. The Intelligent Compaction roller was used to compact embankment fill, subgrade, plant mixed lightly bound material and unbound granular base material. The use of Intelligent Compaction on this project has assisted TMR to evaluate the benefit of the technology and develop a strategy to implement Intelligent Compaction into TMR’s standard specifications.

To support the implementation of PSTS116 and the wider use of Intelligent Compaction in Australia, NACOE has also funded updates to the international Veta software to allow it to be used in Australia and support GDA 2020. The Veta software was developed by the Transtec Group in 2012, and is used around the world to interpret and analyse Intelligent Compaction, Paver-Mounted Thermal Profiles (PMTP), Dielectric Profile System (DPS), and future emerging Intelligent Construction Technologies (ICT).

INTELLIGENT COMPACTION IN ACTION NACOE was pleased to work with the Logan City Council on the Logan Street Pavement Rehabilitation Project, completed in late 2019, the first of its kind in Australia to capture data that allows the council to manage unstable ground in a more efficient way using Intelligent Compaction technology.

The project won the Local Government Managers Australia (Queensland) Excellence Award in 2020 in the collaboration category and included a collaboration of multiple parties: Logan City Council, NACOE and Queensland University of Technology (QUT). It has generated ideas in the road industry on how local governments can play a leading role in cutting-edge road research and the development of innovative technologies.

ROAD SURFACING AND DESIGN

VIRTUAL REALITY ENABLING ‘TEST DRIVES’ OF ROAD PLANNING

Older pedestrians are overrepresented in road fatalities, with a recent report from Victoria’s Transport Accident Commission finding people aged 70 and over account for 32 per cent of the state’s pedestrian deaths, despite representing only ten per cent of the population.

R

esearch suggests road intersection design, crossing widths, location and timing of traffic lights, and density and type of traffic, all play a part in the overrepresentation of older people in road accidents.

While urban planners strive to consider all these dimensions when designing pedestrian areas, it is often very difficult to accurately predict the interaction of so many elements until they come together in a real-world scenario.

A new research project from the University of South Australia will deliver a novel solution to this design challenge, simulating upgrades to roads, crossings and footpaths using virtual reality (VR) technology in order to improve safety for elderly pedestrians.

EXPERT RESEARCHERS TEAM UP Researchers from UniSA’s Australian Research Centre for Interactive and Virtual Environments and Brain-BehaviourBody Research Concentration will develop a walkable VR environment suitable for use by older people, which will

68

March 2021 // Issue 18

help planners and engineers design and test better roads and footpaths.

Supported through funding from the Road Safety Innovation Fund (RSIF), the interdisciplinary project draws upon the expertise of three UniSA researchers from diverse fields – construction management expert Dr Jun Ahn, VR technologist Dr Gun Lee, and cognitive psychologist Dr Ancret Szpak.

“Having access to a wide range of data from both virtual and real environments means we can overcome the limitations of previous ways of assessing pedestrian safety,” Dr Ahn said.

“Through this project we will create a virtual environment to simulate the road environment.

“We can easily change that virtual model to test the impact that a range of factors, such as intersection designs, crossing widths and traffic signals, have on road safety.

“The project will focus on the needs of older people, who may, for example, have impaired vision or hearing, need a walking aid, or require longer to cross the road than young people.”

The interdisciplinary nature of the project reflects the diverse challenges faced by the research team, which must not only precisely evaluate the real-world challenges encountered by older pedestrians, but also accurately recreate those challenges in an adaptable virtual environment.

“Our research combines areas of human-computer interaction, psychology, neuroscience and safety science,” Dr Szpak said.

“Each team member adds a unique perspective which has led us to develop an innovative methodology for measuring pedestrian safety factors for vulnerable road users.”

VR LOCOMOTION TECHNIQUES The research will draw data from multiple user experience methods including eye-tracking, ThinkAloud techniques (asking participants to verbalise their thoughts), and wearable biosensors to track physiological indicators of stress such as heart rate, skin conductance response and movement. Many of these techniques have already been successfully trialled through a pilot study at Glenelg in Adelaide.

“In the pilot study, we used eye-tracking and biosensors to identify stressors and challenges older pedestrians faced when navigating a busy Adelaide area,” Dr Szpak said.

“This new project will extend this pilot study by including a virtual reality user experience to gain further insights into pedestrian behaviour.”

The development of the VR environment will begin with testing a range of different ‘VR locomotion techniques’ – essentially the means through which participants interact with the testing platform – in order to make a VR environment suitable to older people’s particular walking characteristics.

VR technologist, Dr Gun Lee

“Recreating the physical environment in VR is time consuming and challenging,” Dr Lee said.

“As we cannot model every detail, we have to decide the right level of detail, so that VR simulation will reflect the reality enough for assessing and testing the new design of the road.

“We are working hard to explore various technical alternatives to find the right tools to achieve the goal.”

EXPANDING TO OTHER INFRASTRUCTURE PLANNING SCENARIOS Over the course of the three-year study, researchers will compare vulnerable pedestrians’ experiences in real environments with experiences captured in the virtual environment they develop, refining the VR experience until it accurately reflects real life.

“Our ultimate ambition is for councils to be able to use this technology to test road designs virtually with vulnerable pedestrians while still in the planning stages,” Dr Ahn said.

“This means city planners can get an idea of how safe and usable the built environment will be and address any road safety issues well before construction begins.”

The researchers also believe the method they will develop could be adapted to a range of other infrastructure scenarios, allowing planners to ‘test drive’ designs and iron out any issues before committing to the costly construction phase.

“If we can demonstrate the effectiveness of our methodology, there are many other areas of urban planning that could benefit, such as construction sites, shared spaces with pedestrians and vehicles, and new urban development projects across Australia,” Dr Szpak said.

ROAD SURFACING AND DESIGN

ROAD MATERIALS UNDER THE MICROSCOPE

by Michelle Goldsmith, Journalist, Infrastructure magazine

The materials used in construction are of vital importance to a road’s safety, performance, maintenance requirements and longevity. They also significantly affect the construction costs of a road project and the total lifecycle cost of the asset. In the first article in a series on road construction materials, Infrastructure takes a closer look at the different layers making up a road and the varying properties required for different applications.

C

urrently, the majority of Australia’s biggest and most expensive infrastructure projects underway involve constructing or upgrading our roads.

According to 2017 estimates, road projects spend around $5.1 million per lane kilometre on average, varying by road class.

The pavement materials contribute significantly to these costs, at an average of $233 per square metre for an urban motorway or freeway, or $114 for a major rural road. Heavily trafficked major roads are the most expensive, while more minor roads with a lower-traffic load tend to be cheaper.

A wide range of materials can be incorporated into roads, with different mixes exhibiting different properties that affect their suitability for various applications and environments.

Foremost, the material mixes used for this essential infrastructure must be fit-for-purpose due to the significant implications for the road safety, functionality, longevity, maintenance requirements, and total lifecycle costs.

For any road project, careful consideration of the materials used is required, especially when certain materials are in short supply, or when looking to reduce costs and waste, while optimising infrastructure performance.

MATCHING MATERIAL AND APPLICATION A variety of factors affect the materials that might be suitable for any given road project. For instance, a heavily trafficked road in a high-rainfall area will have different requirements to a minor local road in a dry area.

Key factors affecting road material suitability include: ♦ The intrinsic physical properties of the material (e.g. structural stability, heat resistance, water permeability) ♦ The intensity of traffic loads ♦ The climate and moisture regime of the environment ♦ The availability of material sources ♦ Budget constraints

70

March 2021 // Issue 18

The available road materials and their properties have significant implications for the structural design of the pavement and entirety of the road. If suboptimal materials for the application and environment must be used, additional measures will need to be taken to ensure the road meets performance standards. These may include different pavement structures to increase durability, with different material mixes in various layers, or supplementary drainage to limit moisture on the road.

LET’S GET PHYSICAL Different available materials have different intrinsic properties that will determine their performance in pavement mixes.

Some of the most important physical characteristics of road materials are: ♦ Water permeability ♦ Fines content (the amount of fine soil particles) ♦ Plasticity characteristics (ability to undergo permanent deformation under stress) ♦ Stability ♦ Viscosity ♦ Durability ♦ Toxicity The relative importance of each of these factors depends on the individual application. Ideally, the more moisture a road will be exposed to, the lower the materials’ water permeability should be to reduce failure risk, and the more important the fines content and plasticity characteristics. Likewise, the higher the traffic load the road will experience, the more stable and durable the materials should be.

A BIG PICTURE UNDERSTANDING OF PAVEMENT A pavement structure comprises various layers of materials.

Each layer spreads the imposed traffic load to the underlying layers, meaning the stress experienced by the materials is

www.infrastructuremagazine.com.au

ROAD SURFACING AND DESIGN

highest at the surface of the road and lowest at the deepest level. As a result, the quality of pavement materials is usually highest at the surface, with quality decreasing by layer as stress is reduced.

A multitude of possible pavement structures are available, incorporating different materials in various mixes in each layer.

The layers can be categorised as: the wearing course (the surface of the road), the basecourse, the subbase, and the subgrade.

Each layer has different requirements, affecting which materials, and in what mix, are suitable.

of the road, meaning that its surface characteristics (such as appearance and how it feels to drive on) need to meet community expectations.

Options include: hot mix asphalt, bituminous spray seal, bituminous slurry seal (microsurfacing), and unsealed.

Basecourse The basecourse provides support to the overlying surface layer and distributes the load to the underlying subbase.

Options include: hot mix asphalt, concrete, unbound granular, modified unbound granular, lightly bound or bound stabilised granular.

Subbase The subbase provides underlying support to the basecourse and wearing course, and distributes the load to the subgrade layer beneath it.

Options include: concrete, unbound granular, modified unbound granular, and lightly bound or bound stabilised granular.

Wearing course The wearing course, or road surface, experiences the most load stress and exposure to the elements of any pavement layer. It must provide a safe, economical and durable surface in all weather (e.g. not become dangerously slippery when wet) and protect the lower layers from moisture, which could result in damage. Ideally, it should provide a dust-free surface to drive on, reduce vehicle operating and maintenance costs, and extend the lifespan of the overall pavement structure. It is also the visible layer

Subgrade The subgrade is the bottom layer of the road and provides a foundation for the overlying materials. As such, the strength of the subgrade determines the required thickness of the overlying layers and factors strongly in pavement design considerations.

It is often the in situ material, which has been compacted and prepared to make a formation above the natural surface.

Sometimes, stabilisation or modification (such as lime stabilisation) of the subgrade material is undertaken to increase foundation strength.

Options include: in situ granular, and stabilised granular.

This article is part one in a series looking at the different materials used in road construction. Look out for part two in the next issue of Infrastructure magazine, which will go into more detail on asphalt mixes and sprayed bituminous materials. www.infrastructuremagazine.com.au

INFRASTRUCTURE SKILLS IN A POST-COVID WORLD

by Claire Parry, Managing Director, Infrastructure Skills Advisory

Governments across the world are looking for strategies for fast economic recovery following world-changing events, such as the current pandemic. Part of their solution is to leverage their own investments, by fast-tracking infrastructure projects to create new jobs and business opportunities, particularly with existing skills shortages in the construction sector. If poorly implemented, however, rather than providing a sustainable economic solution with long-term business and employment opportunities, it may simply be a short-term fix.

TRAINING AND SKILLS

nfrastructure delivery involves high-risk environments demanding the highest safety standards, and often complex skills and competencies. It is not feasible to move people from COVID-impacted industries such as retail, hospitality and tourism, directly into infrastructure jobs, many of which require very different technical skill sets, qualifications and experience.

The construction sector has long experienced skills shortages and gaps in key trade, technical and professional occupations across civil, commercial and domestic subsectors. Its workforce is aging, and new technologies require new and different skills. There are insufficient numbers of young people entering the industry to meet existing demand.

The current infrastructure boom, together with the fasttracking of projects, will further exacerbate these shortages and gaps. Government is also supporting the domestic construction market through low interest rates, grants and subsidies, which decreases the availability of skilled or semiskilled workers to transfer from other construction sectors.

The industry is also heavily supported by ‘imported talent’.

Skills shortages and gaps may further increase if migration into Australia continues to be restricted.

PROGRAMS AND INCENTIVES THAT COULD HELP Developing economic stimulus strategies through infrastructure delivery without specific programs and incentives to support new entrants, whether from other industries or from underrepresented groups, will fail to deliver anticipated outcomes.

Opportunities exist for rapid employment and the longerterm development of highly skilled ‘homegrown’ future talent if appropriate strategies and support mechanisms are provided.

Private sector incentives and government procurement mechanisms will help the government purchase wider economic benefits alongside traditional goods, works and services.

74

March 2021 // Issue 18

Governments around the world have increasingly used policy and procurement mechanisms to achieve economic and social benefits through spending. Infrastructure delivery is thus linked to wider government objectives, such as employment for underrepresented groups and the retention and growth of regional populations. This approach could be further leveraged to drive opportunities for those most impacted by COVID-19.

Strategies should include robust but realistic contractual obligations that promote business capability while delivering socio-economic outcomes. The best examples are where government and industry have worked together to identify and deliver the right strategy.

When the current infrastructure boom ends, an oversupply of workers may result in unemployment rising. However, construction offers its workforces opportunities to develop highly transferable technical skills that increase employability, either within the operations and maintenance of infrastructure assets or in other industries.

A ‘WHOLE OF GOVERNMENT’ APPROACH Transport for NSW (TfNSW) established a Jobs, Skills and Industry Participation Advisory Group, and an Aboriginal Working Group for the Regional Rail Project, based in Dubbo.

Its key objectives are to increase employment and business opportunities, workforce diversity and regional skills. Group members include NSW and Australian Government agencies, which assist TfNSW and its contractor partners to achieve contractual obligations for jobs, skills and industry participation.

This ‘whole of government’ approach brings together agencies and delivery providers that are directly responsible for the funding and delivery of employment and skills programs, with the contractors that will provide the jobs.

Project delivery, and the operation and maintenance of assets require a range of skills in both construction and nonconstruction roles. Where local supply does not meet demand, training programs and other interventions are needed. www.infrastructuremagazine.com.au

TRAINING AND SKILLS

These may range from pre-employment programs for new entrant construction operatives to upskilling programs for those transferring from other industries. Ongoing collaboration is required across government, industry and educational institutions to establish employment and skills programs.

PLANNING NEEDS TO BE FOR THE LONG TERM There also needs to be investment in programs that will increase capacity in the longer term. Local school programs, supporting STEM subjects, and university partnerships that increase knowledge transfer, or provide cadetships and graduate opportunities, will contribute to future skills supply.

Victoria’s Big Build Graduate Program provides placements across high-profile projects, including the Level Crossing Removal project. Balit Barring provides Aboriginal pathways to the graduate program. ‘Training for the Future’ is the government skills and industry capability development initiative for rail and infrastructure, which offers people from marginalised backgrounds, including refugees and asylum seekers, skills and qualifications for employment in the Victorian rail industry.

New entrant pathways and attraction strategies are required to draw immediate and future talent, including those with transferable skills from other industries, and groups currently underrepresented in the industry, including women, Indigenous Australians and young people. These will be optimised where combined with more flexible working conditions and improved diversity and inclusion strategies to attract and retain underrepresented groups.

Government should identify and capitalise on longer-term

opportunities. Inland Rail will provide jobs directly through its delivery and operation, but also indirectly through developments along the alignment, providing long-term employment and business opportunities.

NSW Regional Growth Development Corporation, working with cross-government agencies and educational institutions, is developing a Jobs and Skills Strategy for its Parkes Special Activation Precinct. The strategy will identify transferable skills from the infrastructure delivery phase and other industries, and implement an employee attraction strategy and skills development program to provide around 3,000 new long-term jobs in the precinct.

ONGOING SKILLS DEVELOPMENT There are opportunities to do more. Where large programs of work are planned, a more holistic approach could be taken across multiple projects or packages of work to achieve more sustainable outcomes. Programs that deliver employment outcomes are often limited by the duration of projects. New entrants may not access or retain further employment due to limited skills, and apprentices and trainees may be unable to complete their qualifications.

To break this cycle, the government could establish centralised ‘labour pools’. Contractors would be ‘host employers’ for the duration of their project, after which workers would be mobilised across future projects within the program. This decreases risk for employers, provides more certainty for workers and allows for ongoing skills development, enhancing career opportunities and increasing industry capability through a more skilled and productive workforce.

Infrastructure Skills Advisory has 20 years of experience delivering socio-economic growth and positive social outcomes through jobs and skills strategies.

SPATIAL & GIS

From condition monitoring on remote assets to mapping the spread of bushfires, drones have had a significant impact on many sectors in recent years, including infrastructure. But the technology has even more potential for the future, including a predicted economic boost of $14.5 billion in GDP for Australia and the creation of 5,500 full-time jobs each year, over the next 20 years.

T

hese figures come from a recent Deloitte Access Economics report, commissioned by the Federal Government, which investigated the economic benefit of drones in Australia, from growth of the drone industry itself, to the cost savings and productivity benefits it can provide to other sectors, including construction and transport. The report quantifies the potential benefits and savings broader drone use could have for the nation’s economy over five, ten and 20 year periods.

The key findings from the report include: ♦ The growth of drone use is expected to create and support 5,500 full-time equivalent jobs, on average, each year over the next 20 years in Australia ♦ Expanding drone and aerial taxi use is expected to provide a $14.5 billion increase in GDP over the next 20 years – of which $4.4 billion would be in regional areas across New South Wales, Queensland and Victoria ♦ The growth of the drone sector is expected to deliver significant cost savings to businesses of around $9.3 billion over the next 20 years, with $2.95 billion of this in the agriculture, forestry and fisheries industries, $2.4 billion in mining and $1.34 billion in construction The report finds the economic potential of drones is estimated to be significant across Australia’s states and territories as well as major cities. It estimates that the present value of the deviation in real GRP over 2020 to 2040 for each state amounts to: WA – $2.5 billion; NT – $0.2 billion; SA – $1.2 billion; Brisbane – $2.0 billion; the rest of QLD – $1.8 billion; Sydney – $1.6 billion; the rest of NSW – $1.8 billion; Melbourne – $2 billion; the rest of VIC – $0.8 billion; and Tasmania – $0.4 billion.

These predictions are based on a scenario-based economic modelling approach, which outlines what could happen in the future so industry and government can be aware of risks and opportunities.

In addition to this report, the Australian Government is also planning to work with industry to develop and implement a National Emerging Aviation Technologies Policy. This policy will support the development, jobs and growth of the emerging aviation sector, including drones and aerial taxis.

IMPLEMENTATION OF DRONE TECHNOLOGY In this context, “drones” refers to unmanned aerial vehicles (UAV), remotely piloted aerial systems (RPAS), as well as unmanned aerial systems (UAS). The technology can range from basic (GPS sensor, inertial sensors, image sensors and range sensors) to more specialised drones with thermal sensors, hyper-spectral and multispectral sensors.

The popularity of drones in the market began around 2015, and since then the technology has continued to

March 2021 // Issue 18

77

SPATIAL & GIS improve and become more accessible. For many sectors, commercial drone applications are still in the early to middle stages of development which suggests significant potential for the future.

There are a number of current and future uses for these technologies across multiple industries in Australia that can save time and money, and increase worker safety. Current uses of drone technology include:

Construction Inspections across the infrastructure sector, including on powerlines, bridges and rail assets.

Mining and resources Stockpile measurement/geotechnical modelling, blast and mine reclamation monitoring, and equipment inspection.

Agriculture Crop, livestock and large land monitoring, and crop spraying/ pellet application.

Defence Direct warfare and surveillance activities.

These industry uses are already in place to an extent, but there is still significant potential in these sectors to use the technology to its full potential. Then there are the areas that have been identified as compelling future use cases, which could be seen from around the late 2020s. These uses include the areas of:

Urban mobility Including airport taxi trips, other taxis and inter-city trips.

E-commerce and deliverables The delivery of express parcels, food deliveries, imported pharmaceutical deliveries (with high value/low weight), regional and remote pathology drone deliveries, medical deliveries in remote areas and some cargo-airfreight.

Government and community services Such as emergency ambulance responses, fire response, search and rescue, border patrol, local law enforcement, disaster management and monitoring, conservation management, mapping and research.

Predicted growth of the drone industry has the potential to create new opportunities by automating production processes, leading to cost savings over the medium to long term. The creation and widespread adoption of new transport services such as urban/regional air mobility and e-commerce/ delivery services also shows enormous potential. The Deloitte Access Economics report found that these passenger and delivery drones, and other Lower Level Airspace (LLAS) vehicles, have the potential to address today’s industry challenges such as road congestion, improved logistics, and to generate new products, services and markets.

In rural areas of Australia, LLAS is already being used by mining companies, and is expected to offer greater operational efficiency in agriculture and to improve deliveries and services to those remote areas. Many new possible applications, particularly in agriculture, infrastructure, security, transport, media and entertainment, telecommunications, mining, and insurance have been recently achieved through significant progress in technological capabilities and regulatory accommodation.

DRONES IN THE CONSTRUCTION SECTOR Some infrastructure companies have been implementing drones for a few years now because of the efficiency gains and reduction in labour costs. In construction, drones are helping operators to survey, map and deliver accurate measurements, and conduct remote condition monitoring and inspections.

Drones can help project managers and designers eliminate risk and identify potential problems through the use of drone maps and 3D models on job sites.

The construction industry has historically been the fastest growing commercial adopter of drones ahead of mining and agriculture. Drone uptake will increase as the technology improves and drones are able to better analyse the data they collect.

Looking to the future, Deloitte Access Economics found that the ability to quickly render 3D maps of terrain could be essential to get the most out of drones. High resolution cameras and data processors will need to be able to survey landscapes at 1mm per pixel. Drones will need improved ‘surveyor grade’ global positioning satellite systems that are better georeferenced so the internal coordinate system of a digital map or aerial photo can be related to a ground system of geographic coordinates.

Deloitte Access Economics estimated that there were approximately 3,715 survey and mapping businesses in Australia in 2019. ABS innovation data1 highlighted that 15.5 per cent of businesses in construction introduced a new or significantly improved operational process. Based on this relationship, the number of businesses using drones in a construction-related activity could be 580 businesses across Australia.

Total market potential is estimated to be in the order of 38,500 drone units. The adoption curve for construction businesses is broadly reflective of the early automobile adoption curve with an adjustment to reduce growth under all scenarios. Therefore, the number of drones used in construction could range from around 19,000 units under a low uptake scenario, to 33,600 units under a high uptake scenario, by 2040.

When it comes to the cost-savings predictions that drones could provide the construction sector, it was found that the use of drones in the industry could result in labour cost savings between $130 million to $310 million in 2040 in the low to high uptake scenarios, which is in addition to the increased safety benefits.

These predicted cost savings come from drones being used to substitute existing labour intensive processes in construction such as surveying and inspections. In practice, builders can use drones to collect real-time data about projects and understand on-site conditions to track progress, as well as helping to catch problems before project timelines are delayed.

Complementary software enables builders to use site mapping data to plan, communicate and keep projects on schedule. Further to these potential operating efficiencies, drones also offer occupational health and safety benefits in the form of safer work environments.

POTENTIAL FUTURE TRANSFORMATION OF MOBILITY/TRANSPORT When it comes to mobility and transport, there are two potential ways drones could be implemented in the future, with technology currently in the works, these are: Urban Air Mobility (UAM) – an alternative mode of passenger transport in the form of aerial, vertical take-off and landing (VTOL) and eVTOL passenger drones; and e-commerce and drone deliveries. www.infrastructuremagazine.com.au

SPATIAL & GIS

Urban Air Mobility (UAM) Urban Air Mobility (UAM) is still in the early stages of its technology lifecycle, with some global companies designing prototypes and undertaking trials. Some of the uses for UAM include airport transfers where passengers use drone technology to journey to and from major airports and central business districts, as well as point-to-point transfers where passengers use drones to journey between infrastructure nodes, which are likely to be located in high population density regions such as inner city/urban hubs.

Deloitte Access Economics found that there are varying viewpoints on the potential year of introduction and adoption paths for this technology. In line with the opinion of those entities consulted, including CASA and AA, its report assumes early introduction in controlled areas between 2023-2025 with more widespread adoption not occurring till later in the decade (around 2030).

The main barriers to the adoption of UAM include physical infrastructure (where they would land) and networks (the need for high speed/low latency networks, effective crash avoidance systems, capacity in electricity grids etc.). The market benefits for UAM are represented by the travel time savings accruing to business passengers. Under a low uptake scenario, these travel time savings are estimated at around $6 million in 2040, increasing to around $66 million in a medium uptake scenario, and $91 million under high uptake. Cumulatively, travel time savings over the period 2020 to 2040 amount to around $24-$453 million under the various scenarios.

E-commerce and drone deliveries An implementation that’s more likely to occur in the next few years is the use of the technology to deliver goods using automated drones to carry packages from a distribution hub to a drop-off location. Deloitte Access Economics’ report looked specifically at three types of e-commerce and drone deliveries including express parcels to complete the ‘last leg’ of a delivery; food deliveries; and pathology deliveries of samples from local medical centres to hospitals and testing labs.

The report predicts that Australia’s relatively fast adoption of new technologies and the geographical spread of cities could be a catalyst for a relatively fast uptake of this technology, with early adoption already occurring and more widespread use predicted over the next 2-3 years (around 2023).

Express parcel deliveries offer the greatest opportunity for cost savings on a per delivery basis (around $205 to $340 million in cost savings in 2040), followed by food (around $80 to $110 million) and pathology (around $35 to $75 million).

Relatively low upfront capital and operating costs (including labour costs) lend themselves to sizable cost savings.

You can already see some real-life examples of this type of utilisation with Amazon running Amazon Prime Air, which seeks to automate last-mile delivery of packages using small drones, as well as Swiss Post, Matternet and Posti who have been testing parcel deliveries by UAV since 2015.

DRONES IN GOVERNMENT SERVICES Drones are currently implemented in the public sector for a number of uses including disaster management and recovery, firefighting, and monitoring/inspection of infrastructure. If there are fires, drones can be used to detect the locations, and thermal imaging cameras can see through smoke and assist first responders to deploy assets efficiently.

Post-disaster, drones can be used to survey or map scenes to assess damages, or even to search for missing people. They can also be used in other areas such as police, customs or border control e.g. mapping cities for disaster management efforts, monitoring ports and patrolling coastline.

Drones offer significant cost, efficiency and safety benefits as these activities are typically labour intensive. Drones are already in use throughout Australia for government services, for example in Western Australia, drones were used by the state police force to deliver public announcements at public spaces to assist in enforcing COVID-19 rules.

Deloitte Access Economics predicts lower scale drone uptake is assumed within government services, with widespread acquisitions occurring over the decade to 2030.

Widespread adoption to 2030 is supported across Australia in terms of civil government applications that are less subject to infrastructure and telecommunication network limitations.

Use in government services has the potential to achieve labour cost savings between $85-$325 million in 2040. As many of the drone use cases for government services involve surveillance and mapping, labour cost savings are assumed to be comparable with those in the construction and mining industries at around 30 per cent over the case without drones.
