president’s Report Firstly, thank you for the opportunity to become the 25th IPWEAQ President. I was declared elected at the AGM held 24 October 2019 after serving on the Board as Vice President (2017-2019) and as CQ Branch President (2015-2017). The IPWEAQ Board for 2019-2021 comprises: • Re-elected Board members • Vice President: Angela Fry, GHD (2017) • CQ Branch President: Celisa Faulkner, Gladstone Regional Council (2017) • SEQ Branch President: Raad Jarjees, Cardno (2017) Newly elected Board members: • NQ Branch President: Glenda Kirk, Mareeba Shire Council • SWQ Branch President: Andrew Johnson, Somerset Regional Council • Sarah Hausler, McCullough Robertson • Trevor Dean, Fraser Coast Regional Council I’d like to thank retiring Board members Gerard Read, Andrew Ryan and Bruce Gardiner for their contributions over the past 2-4 years, and Seren McKenzie who completed 10 years’ service on

the IPWEAQ Board in various roles including SWQ Branch President, Vice President and as our President. Seren is one of the longest-standing Board members in IPWEAQ history and we are delighted that she is continuing her involvement on the SWQ Branch committee. At a General Meeting of members held 24 October, it was resolved to transition to a Company Limited by Guarantee – a more formal and appropriate structure given the nature of our activities, and a supporting constitution was adopted. Many thanks to the 126 members who voted in person at the meeting or by Proxy. 125 votes were received in favour. The new Board met for the first time Friday 25 October, technically and officially, for the first time, as a Board of Directors under Corporations Law as opposed to a Management Committee under state based legislation. Not much changes in terms of our operations – our ABN remains the same and all our structures remain in place, and we continue to be governed primarily by ACNC (Australian Charities and Not-forprofits Commission) legislation since we are a registered charity. However, the new structure and ASIC oversight does offer a more robust governance framework which offers those we trade with more security and confidence in their dealings with us.

Engineering for Public Works | December 2019





Each President nominates a charity for us to support during their term. Seren McKenzie chose MS Queensland and we are delighted to announce that $22,568.60 was raised during the two years of Seren’s presidency, a record donation for a President’s Charity. Fund raising initiatives over the past two years included raffles, lawn bowls, merchandise sales, charity auctions, bike rides and the constant consumption of Freddos by staff in our office. Team IPWEAQ raised enough from the Brissie to Bay ride to purchase an electric bed for an MS sufferer ($3,868) while the auction of Col Chandler’s beautiful seascape raised $3,800. During Seren’s two-year presidency, she nominated MS Queensland as the President’s Charity. Our commitment to raising awareness and funds for this illness was vital, as there is currently no cure for the disease. #IPWEAQ19 finished Seren’s inspiring presidency and with that, an incredible $22,568.6‬0 was raised! The finale for our MSQ fundraising was the #IPWEAQ19 Charity

Auction. Thank you to Scott Williams of Complete Urban who secured the winning bid for the ‘Magnificent Melbourne trip for two’! This very generous prize was donated by Pickles and included two nights at the luxurious InterContinental Rialto in Melbourne with all the trimmings. One lucky door prize winner also walked away with a car care pack valued at over $1,000.

with Craig Murrell who has chosen Rural Aid as his President’s Charity. As one of the largest rural charities in Australia, Rural Aid’s focus is twofold: provide support to farmers and rural communities in times of natural disaster and support the sustainability of the agricultural sector. We look forward to supporting Rural Aid for the next two years.

Thank you for everyone who has supported this deserving cause over the past two years! We look forward to creating new and exciting fundraising initiatives

memership feature                                    Congratulations Chris Lawson who celebrates 40 years as a member of IPWEAQ My career in local government began when I was awarded a cadetship in 1971 by Townsville City Council to study civil engineering at James Cook University. I still count those years in Townsville and at JCU as amongst the best of my life where I made many life-long friends. I’m also grateful to my various mentors at TCC for throwing me in the deep end but with support and for giving me a love for engineering which lasts to this day. I interrupted my time at TCC with 2 years in the USA studying and undertaking research into soil stabilisation. On my return to TCC I was soon charged with the normal stuff of roads, pavements, stormwater drainage, water and sewerage, and added roles in computerised mapping (predecessor to GIS) and asset management and these have carried me through my entire career. It was in 1979 when I prepared a paper for the Local Government Engineers and Overseers Association conference in Townsville that I first joined our august organisation. In all, I served 23 years in local government with TCC, then Logan and later Warwick and Beaudesert. My time with local government was interrupted by 5 years at Neville Jones and Associates where I was fortunate enough,

with the late Neville Jones, to write the Queensland Urban Drainage Manual and be heavily involved in the Standard Drawings and the first Qld Streets. Any of these publications might be considered career highlights in my time in or around local government but there are others. Amalgamations have been a challenge for many of us. I was fortunate enough to be involved after the first amalgamation at Warwick and was given a significant role in bringing together four disparate workforces, with widely varying work practices. With the willing help of the workforce we created something new and the outcome at the time was exhilarating. We downsized our plant fleet, modernised fleet operations, standardised fleet purchasing, introduced fleet leasing, introduced planned maintenance and works orders, introduced structured training and career path planning, achieved QA, Safety and Environmental accreditation, introduced GIS and asset management. It was great fun and I remain grateful to those at Warwick who allowed me the professional freedom and provided the support for this to happen. It was satisfying and exciting to see the development of all staff as they embraced new opportunities. With my experience from USA and from Townsville with stabilisation, while employed at Warwick undertaking a job for Main Roads, I managed to convince Main Roads

Engineering for Public Works | December 2019

through their Peter Evans (once an Ipswich City Council employee) to once more undertake insitu lime stabilisation, something they had dismissed as ineffective following a couple of failed projects which in hindsight were never designed to work. The collaboration of two local government engineers paved the way for a process that almost everyone now implements. After Beaudesert, I moved back into consulting with Connell Wagner (now Aurecon). This move was an entirely different experience. I came face to face with much larger and more complex projects than I had ever experienced in local government. Such projects included tunnels (for Brisbane City Council), busways, passenger and heavy rail, bulk materials handling and ports, hospitals at the Gold and Sunshine Coasts and road projects such as Toowoomba Range Second Crossing. In many of these projects


I was able to use my experience in local government for the benefit of projects and clients. With the complexity and size of some of these projects (in the range of $100M to over $1B) came the need for more sophisticated design techniques and software (including 3D modelling), document control and management, project control and management. In the couple of years prior to my retirement as Regional Manager of Aurecon in 2015, the push for BIM came to the fore but its promise seems to be just as far away now as it was then while IPWEAQ with its ADAC remains leading practice.

I was lucky enough to be elected to serve IPWEAQ on a number of occasions in the early 1990s and remained in contact as it transitioned from the organisation run by the late Ray Moore to Suzannah Barnes-Gillard at the time of the Beaudesert Conference in 2001. With my move to Connell Wagner in 2005 I was unable to maintain that same involvement although I managed to review a few changes to QUDM.

Engineering Advisory Board at Griffith University. I see my involvement on the Board at GU as an opportunity to participate in keeping engineering contemporary into the future. I feel honoured to have been able to serve our local communities either directly or indirectly and to have served our members in IPWEA. Local Government and engineering have been good to me.

In retirement I remain involved through advisory boards to two local governments and a water authority and I chair the

CEO’s Report I had thought 2018 was fastpaced but 2019 now makes 2018 feel like a Sunday walk in the park. It has been another successful year for IPWEAQ with strong financial results (a net profit of $111,993), membership growth of 12% (13% growth for younger professionals) and recordbreaking conferences with over 2,000 delegates attending an IPWEAQ conference or course over the past 12 months. With almost 600 delegates at the Excellence Awards dinner/ ceremony and 525 delegates at the 2019 Annual Conference, we can lay claim to the biggest, most attended, premier event for professionals in our sector in Australasia. We also expanded our capability with four new roles created this year focussing on campaigns for younger professionals, rural/ regional communities (Go West), professional development and technical solutions. Plans are underway to recruit two more employees in the New Year and to relocate to larger offices since we outgrew our current premises earlier this year. A number of new courses and new technical solutions were launched this year and reviews initiated of governing structures (ADAC) and publications (Supervisor’s Handbook). And there is much more planned or in progress for launch in 2020 as we continue to

listen to you and focus on your needs.

awards and our President’s Charity, Rural Aid.

We’ve collaborated extensively with state government and other professional associations and peak bodies developing joint initiatives across the sector. We engage regularly with the QRA and QAO and we’ve signed cooperative agreements with the Local Government Financial Professionals (LGFP) and AAPA, and continue to work closely with the ARRB Group.

We have seven more key events following the Breakfast commencing with the SWQ Branch conference in Stanthorpe, 20-22 February, a new Asset Management Symposium in Brisbane in April, the CQ Branch conference in Maryborough late April, the second Rural Roads & Maintenance Forum in Dalby in May, the SEQ Branch Conference in Caloundra also in May and the NQ Branch conference in Townsville in June. The Annual Conference next year will be in Cairns in November.

We are already well into planning mode for 2020 with the President’s Breakfast in February recognising the contribution to our successes from our Partners and sponsors. The Breakfast will also launch the 2020 excellence

corporate structure – a Company Limited by Guarantee (CLBG) with a supporting constitution that ensures we are in a position to respond to whatever challenges come our way. It was a proud moment to see the Institute effectively grow up – a CLBG is a more respected corporate structure which offers confidence and security to those who trade with us. So while 2018 seemed fastpaced and 2019 sped past like the Shinkansen, there is no sign that we will be easing up with 2020 on approach.

Josh Flanders Civil Engineer, Capital Project Delivery Cairns Regional Council, IPWEAQ Ambassador If I were to tell you 20 years ago that the future of the construction industry is in the use of drones, autonomous vehicles and remote-controlled construction equipment, what

would you say? It would have been hard to imagine in a world where even the iPhone didn’t exist. The simple fact is that smart construction is here, and Komatsu is leading the charge. All great IPWEAQ annual conferences kick off with a selection of Technical Tours on day one, often the highlight for many delegates. This year’s 2019

Engineering for Public Works | December 2019

annual conference in Brisbane was no different. Delegates faced the difficult decision of choosing between four excellent tours, with one of those being the Komatsu Wacol facility tour. Being interested in large, bright, yellow construction machinery since a young age, this tour was an easy pick for myself. It turned out to be much more than this however.


The site, approximately 30 minutes outside of the Brisbane CBD, contains six large buildings across 61,000 square meters of land and is responsible for the sale, service, assembly, and remanufacturing of mining and construction equipment throughout Queensland. The tour commenced with a short presentation highlighting all the latest innovations developed by Komatsu. This included their advanced survey techniques, which are fast becoming common practice. Drones and 3D laser survey scanners quickly and accurately scan the land topography at multiple stages in the project from the first initial survey to continuous monitoring during construction. Intelligent Machine Control (iMC) was another notable point from the presentation due to the wide range of benefits it can

deliver on construction sites. New construction machinery such as dozers and excavators can be optioned with iMC and the 3D design surface of the project can be loaded in. The iMC system in excavators will physically not allow the bucket to extend beyond the design surface, and in dozers, the system automatically controls blade elevation and tilt according to target design data. The result is improvements in work efficiency by up to 60% due to more efficient machine use and less rework. Lastly, the aspect that appealed to everyone’s inner gamer is the ability to ‘log in’ to work by putting on a virtual reality headset and being able to control construction equipment remotely from the other side of Australia. The tour continued into the oil analysis laboratory, where hundreds of thousands of dollars’ worth of equipment analyse customers’ valuable oil samples. The laboratory operated like a well-oiled production line (pun intended) where each oil sample is analysed by each of the many machines present. Regular testing is critical to ensure any possible problems in the oil are discovered early. I was amazed to hear that approximately 500 samples are


tested daily and there is constant demand. This conveys just how large the customer network is. Finally the moment we had all been waiting for had come, a walkthrough of the workshop. There were many excavators, loaders, graders and other equipment. The stars of the show however were a large mining spec bulldozer as well as a wheel loader built for mining. Seeing factory workers on these large machines truly put their size into perspective. The main workshop was adjacent to the largest spray booth of its type in the southern hemisphere, which we were able to have a quick look into. During the tour we were also shown an excavator with iMC control and the group was informed how system knows exactly where the bucket is at all times and how much material has entered and exited the bucket. I thoroughly enjoyed my time during the tour of the Komatsu Wacol facility and would like to extend my thanks to John Tannhill and Komatsu for the opportunity. It was very interesting to learn about and see the current and future happenings in the construction industry and I am excited to see what is to come in this space in the next 20 years.

Congratulations to Clarrisa Campbell from Moreton Bay Regional Council for winning the Geoff Wilmoth Best Paper Award at #IPWEAQ19. Clarrisa’s paper on ‘Stormwater Pipe condition assessment - if only animals could talk’ was voted on by conference delegates. Moreton Bay Regional Council (Council) has nearly 250,000 stormwater assets valued at around 2.0 billion dollars. The large majority of these assets are buried underground and form part of a network, making them very difficult to inspect. To combat this, Council utilises CCTV technology to inspect their buried stormwater assets. Council invested in their own van and camera unit to conduct inspections of stormwater pipes in 2015 and added a second in 2017. The data from these inspections was used to support the creation of a five million dollar per annum renewal program, as well as informing the ongoing maintenance program. Clarrisa’s paper described the history of Council’s CCTV inspection, renewal, and maintenance programs, provide a number of examples of interesting projects Council has come across over the years, compare some of the alternative pipe inspection technologies, and discuss some of the lessons learnt; including that stormwater pipes are a favourite hideout for a myriad of animals. Clarissa is also our YIPWEAQ representative on the national YIPWEA committee participating on a national level to share ideas and to bring these back to IPWEAQ. You can read more on Clarissa’s award winning paper in the September 2019 issue of EWP.

Sean Rice (Ricey) is the Managing Director of Proterra Group. He is a qualified Civil Engineer graduating with Honours from the University of New South Wales (NSW) in Sydney, holds an MBA (TechMgt), CPEng, RPEQ, NER and is a fellow of IPWEAQ. He is very much your stock standard engineer for regional local government and has worked for most of his career as a project manager on public works infrastructure projects for regional councils. Ricey has worked in local government for over 20 years and is passionate about encouraging councils to collaborate on their projects to ensure they aren’t continually reinventing the wheel, and repeating mistakes already made by other councils. He is a country boy at heart and is always up for a yarn so if you’re ever chasing some info or looking for a referral on who can do what in your region, give him a call. EPW: Please tell us about yourself: where are you from, what are your interests, what makes you tick? SR: My wife Mel and I along with a bunch of kids have called Goondiwindi home for the past 14 years, although we actually live on the NSW side of the border

on a farm so I can wake up each morning with that beautiful fresh NSW air! I am a heavy, yet humble Blues Supporter. My favourite things are hard work during the week to pay the bills, then hiking, travel, red wine and amazing foodie experiences, adventure bike riding on my KTM690 and spending time with my kids (six) and foster kids (two). We’ve got a fairly funny farm at our joint and I wouldn’t have it any other way. Luckily, I have a very supportive wife, or perhaps she has a very supportive husband. EPW: Please summarise your career to date in your own words.

Engineering for Public Works | December 2019

SR: I was born and raised in the Back O’Bourke NSW, then a couple of years boarding school in Bathurst before doing a Civil Engineering Degree at the UNSW in Sydney. Mel and I had two kids by the time we finished Uni, and aside from all my efforts to head to London for work Mel (who was from Sydney) said she loved Bourke, so we went back there for 10 years. I worked in local government for eight of those, finishing as the Director of Engineering in Bourke Shire before moving into private industry where I was the General Manager of an Irrigation and Agricultural Chemical/Fertiliser Business. Due to ongoing drought, around


2005 we made the decision to leave town and ended up working in Construction in Goondiwindi for Sudholz. The work was great, and I ended up in Airlie Beach and Mackay most of the time building dams and subdivisions. Although I enjoyed the work, being away wasn’t good for Mel and the kids as they were missing out on footy training and hugging their Dad, so I took a short-term job back in Goondiwindi to be home more. I still remember Dave Burges, the Waggamba Council Engineer at the time asking me if I wanted to go on a salary for the 6-month gig, or as a contractor. I’d not really thought of it until then but said let’s have a crack at being a contractor. In hindsight, that was a definitive life decision.

EPW: What’s been your most significant career highlight to date? SR: I think the coolest thing was winning the 2002 Engineers Australia Young Engineer of the Year Award, however my highlight would have to be starting Proterra Group. We originally started the business just so I could be home more (I was working away in Construction, and that wasn’t good for our six young kids). What started as a family decision turned into a nice little business that has ensured we’ve had vegemite for our toast each week ever since. Actually, Proterra Group landing the Balonne Shire Council Flood Restoration Project back around 2011 for $120M of works was

pretty cool too. We brought it in 20% below budget using all local contractors with the help of Balonne Shire Councillors and staff. I don’t think I’ll top that in this lifetime, but I can assure you I won’t die wondering. EPW: What do you find most satisfying about working as an engineer in public works? SR: I do have a genuine interest in helping improve the communities where we live. I live in the bush and probably always will. Nothing irritates me more than seeing ratepayer money wasted on big city firms coming to our area with gold plated solutions that we just don’t need. My greatest satisfaction comes from helping councils develop practical

Engineering for Public Works | December 2019


solutions using their existing local resources as much as possible, right across the 35 councils we currently service in NSW and Queensland. Sure, we take our bit, but the majority of funds stays local and I’m extremely proud of it. EPW: Tell us about your experience as an engineer providing technical services to local councils? SR: This is an interesting one for me, as I’m probably the least technical engineer in IPWEAQ, although I do think I can still build a good piece of road. I pride

myself on my management and leadership skills in being able to locate, and bring together the right resources to deliver practical, cost effective projects for our communities. I have other staff who can provide you with technical advice if you want it - they are far more competent than me and I keep their mobile numbers handy.

help. You’re wasting your time and our community’s money.

EPW: What do you appreciate most about your involvement with IPWEAQ? SR: The body of knowledge associated with IPWEAQ is amazing. There isn’t a single public works engineering question that I couldn’t ask to our group that wouldn’t result in an immediate answer, or at the least a referral onto someone who’s knows what I’m chasing. It doesn’t get better than that and I love it.

2. I reckon I’ve learned some great stuff in my career from really good people, and a whole lot of what not to do from others. You need to take note of both.

PS – there’s still a bunch of you people out there reinventing the wheel on projects that have been done before. STOP IT and ask for

Engineering for Public Works | December 2019

EPW: What would be the one piece of advice you would give to others early in their career? SR: 1. Never tell a grader operator how to do his job. We are all part of a big team here so never feel you are better or know more about something than one of your team.

3. If you haven’t got the communication skills to sit down with your team at smoko and have a yarn about the weekend, you’re in the wrong game. EPW: Any other comments/ thoughts/wisdom to share? SR: It costs you nothing to say G’day to someone, or wave to a vehicle as you drive past. That stuffs free and we should sprinkle it everywhere.

ICONIC NOOSA PARK ROAD BOARDWALK IS IPWEAQ PROJECT OF THE YEAR Noosa Council took out the top accolade at this year’s IPWEAQ Excellence Awards for the iconic Noosa Park Road Boardwalk. Project Description Noosa Council has created the iconic $7.5M Park Road Boardwalk nestled between world famous Engineering for Public Works | December 2019

Noosa National Park and Hastings Street. The project is a model example of stakeholder engagement, working with environmental and geotechnical challenges, reducing operational costs yet not compromising on creating a world class public asset. The 400 metre boardwalk is symbolically and positionally a


major contributor to Noosa's near Billion dollar tourism industry. The effort in its planning, design and execution has proudly been matched by the public accolades bestowed upon it. Planning Replacement of the Park Road Boardwalk aimed at delivering public infrastructure to cater for an ever increasing demand, add to the visitor experience by connecting users to the natural environment, improve accessibility and reduce the burden of maintenance costs to the community. The previous boardwalk was approximately 25-30 years old, in a deteriorated condition with many footings exposed, uneven levels and decaying timber. Ongoing maintenance and replacement costs were at a premium and increasingly accelerating over time due to the corrosive conditions,

cost of hardwood timbers, difficult access and high levels of use. The boardwalk structure had passed its serviceable life and was due for replacement. Due to the iconic nature of the site, highlighting the importance of the natural environment as an integrated part of the Noosa region tourism drawcard, Council was unanimous that this project was to demonstrate holistic, sustainable design and innovative construction solutions. In turn it was seen that this would elevate the long term social, cultural and environmental benefits of the area, and provide for a jewel in the crown of the Noosa region. A community project reference group was established to ensure community aspirations for this iconic status were achieved. This team sourced members from local environmental and community groups to review and provide feedback for the overall project

development, planning, design and construction. In order to gauge community expectation of the project a set of parameters were set up for discussion. These included the extent of habitat protection, design features, roadway alterations and the locality of access points to the main structure. These discussion points provided a weighting of the importance each was to the community reference group. The value of this group to assist in decision making provided this project a lot of community good will and support. As the Park Road Boardwalk is a very high profile site, the boardwalk replacement project generated a significant ground swell of community interest. The presentation of options to obtained community input from the Community Reference Group was inevitable and in turn

Engineering for Public Works | December 2019


structure and construction. Project options were then evaluated on community preference, environmental impacts, durability, constructability, traffic and roadway requirements, cost, timing and ability to meet overall project objectives. Of major consideration by Council was material selection and the engineering design of the boardwalk to obtain a minimal environmental impact target.

provided for valuable community support relating to design, environmental values, timing and traffic disruption. By considering the values of the Community Reference Group it provided Council with a set of guiding principles for concept and preliminary design development of the boardwalks alignment,

Material Selection As previous boardwalk sections had created a burden to maintenance crews, the project team place significant effort into the researched of construction materials that met the durability and structural requirements of a subtropical coastal environment. Key findings from researching construction materials proposed the use of:

Engineering for Public Works | December 2019

• Hardwood for the structure to allow for site adjustments around trees; • Accoya Timber for the timber decking and handrail due to its dimensional stability and durability in harsh • environments; and • the use of structural aluminum for the balustrade due to ease of use in the field to respond to alignment changes and avoid conflict with tree and root positions. Once at detailed design phase had been conducted, a Net Present Value (NPV) analysis was undertaken to test the most costeffective material section for the structural design. This analysis determined that the use of the selected materials, listed below, whilst incurring higher initial capital cost, over time the choice was considered more cost effective as a whole of life design.


The use of micro-piles covers the majority of the boardwalk substructure for its 750m length. This piling system allowed for the ability to manoeuvre around tree root systems as well as improve the speed of construction and reduced noise and vibration impacts. For the entire length of the renewed boardwalk, several types of sub-structure were used to support the walking platform including free standing boardwalk, cantilever construction and slab on grade construction using micropiles. For the Park Road Boardwalk to become an iconic jewel in the Noosa Council crown, construction had to be in harmony with the natural environment, involve the community, provide sustainable design features and display innovative construction techniques. Listed are the main project outcomes, and how each was achieved:

Having selected a concept design that achieved the community project reference group objectives, Council embarked on constructing a number of prototypes to allow a better visualisation of the concept shape, verify techniques for achieving the curves and provide for a durability assessment of material choices within a similar environment for a period of one and a half years prior to construction. Over this time the Accoya performed as per manufacturer’s claims, and also extended to matching the rock batter at the shoreline to those

rocks found naturally. Engineering Design The design of the sub-structure for the Park Road Boardwalk required a mechanism that would be able to navigate the lay of the land and avoid the presence of trees and their root systems as assessed in the field. The need for this type of flexible design that was sensitive to its surrounds and able to navigate contouring terrain was a significant required outcome from both Community and Council perspectives.

1. C reating an iconic tourism attraction: This outcome was achieved by: a. Highlighting innovative design features such as rest areas and viewing platforms with the natural features of the landscape and tree canopy; and b. The use of high-quality finishes and innovative construction materials. These achievements have been proven a successful as Park Road Boardwalk images are now a key feature of regional marketing as it provides for an elevated experience compared to previous infrastructure, with Council receiving a flood of positive feedback from residents and local

addressed by the new boardwalk.

2. E nhance the economic value of the boardwalk to the region by providing an improved tourism experience: This outcome was achieved by: a. Improving the peak capacity of the boardwalk with a wider deck, viewing platforms and seating;

The new boardwalk also provides high standards of safety that considers falls, crowd loading, trips and lighting. Review of these items was carried out by range of consultants including; Building Certifiers, Engineers, Architect and Arborist.

b. P roviding improved accessibility for people with disabilities and prams from the Hastings Street to the Noosa National Park. Now the Park Road Boardwalk caters for pedestrians, joggers, parents with prams and surfers carrying surfboards and those with a range of impairments. The economic development assessment of the boardwalk build on the local community estimated an increase in tourism spend by $1,200,000pa. 3. I mproved site accessibility and safety: Council’s attention to detail in the development of design ensured that attention to detail was focused on the multitude of accessibility standards. Whilst wheelchair compliant access is not environmentally possible along the full length of the boardwalk, many other accessibility issues have been

4. Reduce the financial burden of rising maintenance costs to Council: Research into the types of materials to be used in the construction of the Park Road Boardwalk required thorough attention to provide for a high level of infrastructure durability in an ocean front environment. High grade stainless steel finishes and the use of pressure treated Accoya wood has significantly improved the boardwalks durability against environmental elements, which was further assessed field tested prototypes. This has also provided for a significant extension of the life of the boardwalk asset. Currently there are no maintenance requirements of the boardwalk, and due to the expectation of the Accoya to turn a uniform grey, as designed for

and therefore requiring no further wood treatment, which in turn has provided saving regard the cost of maintenance. The Noosa Park Road Boardwalk demonstrates a very comprehensive planning, consultation, planning, design and construction project in a very environmentally sensitive area. And the judges commented that: The Noosa Park Road Boardwalk project overcame many challenges during the planning, design, delivery and operation phases of the project. Key to its success was the close involvement of a Community Project Reference Group engaged two years prior to commencement of construction. The project was successfully delivered in a high-profile, high value environmental area using a detailed project management plan which considered the economic and social benefits of the project, the protection of the environment, and delivering the project within budget and ahead of time. This iconic project achieved more than just a structure but the provision of another jewel in the crown for the Noosa attraction package.

Resurrecting an Australian Icon: Rebuilding the Waltzing Matilda Centre in Outback Queensland #IPWEAQ19 FEATURE

The 2019 IPWEAQ Excellence Awards recognised the reconstruction of the Waltzing Matilda Centre as the winner of the best public works project over $10 million. The judges commented that the modernised and enhanced home for Australia’s unofficial national anthem delivered on the legacy and guarantees a memorable visitor’s experience.

Funded collaboratively by Winton Shire Council and Queensland and Australian Governments, the rebuilding of the Waltzing Matilda Centre was a project of major national significance that delivered a $24 million architectural project with an integrated world class museum experience in outback Queensland. Project Manager and now Director, Asset and Project Services for Peak Services, Brian Jackson described the managing the rebuild of the Waltzing Matilda Centre as a career highlight. Mr Jackson also noted that process and sound management practice aside, the project could not have achieved

Engineering for Public Works | December 2019

such success without strong leadership, a vision, a can-do attitude, hard work, advocacy and resilience of all parties involve from inception through to completion. According to Alan Rayment, former Winton CEO, the length and uniqueness of the project demonstrated how setting clear and simple objectives helped the team make decisions for the good of the project without getting sidetracked. “You’d be naive to think you could build a $24m project in the middle of Australia that would not have some issues.” The Waltzing Matilda Centre (the


Centre) located in Winton, QLD originally opened in 1998 and was subsequently expanded to meet increasing visitor demand in 2004. The Centre included the story of Waltzing Matilda, as well as exhibiting the collection of the Qantilda Museum (of the Winton Historical Society) and providing a venue for touring displays and exhibits. It is the first museum in the world dedicated to a song. Prior to the fire which destroyed the Centre, several themes were integrated (incorporating a museum area) to provide a multifaceted education and tourism experience.

Strong relationships were forged with various tourism and education providers. The Centre was well attended by tourists visiting Winton, attracting around 18,000 visitors per annum. This is an iconic Queensland outback tourist attraction and a vital part of the tourism infrastructure of the Winton region. An electrical fault in the ceiling caused a fire that soon spread in early hours of 18 June 2015. The Winton Shire Mayor at the time, Butch Lenton said the loss of the original Waltzing Matilda Centre was a heavy blow during a major

drought but the community and visitors rallied together to ensure it wasn’t lost forever. The initial scoping of the project identified that improvements could be made in reconstructing the Centre. A functional area relationship diagram was developed and this informed preparation of the initial concept options for the project. Council investigated in detail three options for progressing the project. The analysis, research and investigations allowed for development of a comprehensive multi option business case for

Engineering for Public Works | December 2019


reconstruction of the Centre. The options considered in the business case included: • Option 1: Reconstruct Centre Like-for-like • Option 2: Modernised Centre • Option 3: Modernised and Enhanced Centre While it quickly became evident that Option 3 would best meet the vision and goals of Council, Option 2 could meet a compromised Project vision and goals which could be enhanced with future stages of work and funding. A funding shortfall of $8.0M existed to achieve Option 3.

Option 3 included the reinstatement of pre-existing functions and functional spaces while delivering additional functions and dual/multi use functional spaces to modernise the layout. In addition, this would enhance and support the regions credentials as a tourist, education, business conference and film destination. This option provided opportunity for delivering an alternative and expanded layout of functional areas and built form, a grander street presence, integration of the use of new technologies, expansion of operational capacity (day and night events), thus provided

Engineering for Public Works | December 2019

enhanced future-proofing benefits. This option was considered to deliver the greatest economic, social and environmental benefits for Winton and the region. The business case supported Option 3 and in February 2016 a grant application of $8.0M under the National Stronger Regions Fund Round 3 (NSRF3) was submitted to the Federal Government. At this time, the Project was sitting on a knife edge in development between Option 2 and Option 3 scope. Council had positioned the project in a way that maximised opportunity for a Modernised and Enhanced Centre to be delivered. The reality


was that Council had formed the position through early and mid2016 that it was not going to settle for anything less than Option 3. In early September 2016, the Federal Government approved NSRF3 funding of $8M towards the Centre. A vital strategy for success was to ensure the key resources involved in the planned and design elements understood and appreciated the vision for the project – the project needed experts who “got it”. The competitive open market process identified the best team nationally to design and document the Project. The design and documentation of the project was monitored and controlled to ensure cost, quality and scope were maintained within acceptable tolerances of the Business Case and Project Management Plan requirements. One of the key inputs to the design of the Project was understanding the good and the bad of the previous Centre’s operation and maintenance. These enabled lessons learned from its operation to be incorporated into the Project design philosophy and design outcomes. Many lessons from the previous Centre’s functional layout and functionality were identified, including how staff operated the Centre and how visitors responded to the Centre. This gave great insights into how the Project could improve in terms of operation, maintenance and visitor experience. Construction of the Centre required a Building Contractor capable of delivering such a project in a remote location and Interpretive Contractors capable of

being able to fabricate installations off site for installation in a building under construction. Considerable planning was required to enable the main exhibition area to be practically complete 8 weeks prior to the remaining building works for bump in of interpretive contractor fit-out and multimedia installations. This required clear construction contract provisions and requirements to be established prior to contract formation for respective works.

Winton community and the region, however it will be years before the overall impact of the new Centre can be fully realised. To learn more about this project, the full conference paper and presentation is available through the IPWEAQ Knowledge Centre.

The Contractors delivered their respective works under the Contract successfully to enable delivery of a finished project that is as visually impressive as it is functional. The detailed planning, execution, monitoring and control evolved to create a state-of-theart modern facility designed by industry leading designers in their respective disciplines. The new Waltzing Matilda Centre was officially opened Friday 20 April 2018 following three years of planning and construction to much fan-fare and celebration. It boasts state of the art interpretation, telling the story of Waltzing Matilda. Thousands of people made the trek to Winton to attend the opening. The first full year of operation coincides with final construction contract completion and the operational results of the Centre are outstanding. It is a stunning construction, both in form and interpretive installation and a multi design award winning Centre, with many more Project awards anticipated. Since reopening, visitor numbers have far exceeded what was originally anticipated - 59,000 visitors in the first 14 months of trading. The economic impact of this outcome is significant to the Engineering for Public Works | December 2019



Futures Challenge 2019

The Futures Challenge invites final year students studying engineering and related disciplines to present their thesis or research project at the IPWEAQ Annual onference. Students are asked to prepare an A1 poster board which outlines the key elements of their thesis or research project and present their conclusions, recommendation and outcomes to conference delegates. Participants also deliver a 10 minute presentation to delegates with the winner chosen using the conference app. The Futures Challenge offers participants an opportunity to be involved with our community, meet industry leaders and build their personal profile. And the winner receives a complimentary registration to the 2020 IPWEAQ annual conference. This year we had four impressive candidates presenting varied topics. We asked them to share their Futures Challenge experience and learnings, and why students should become involved in the Futures Challenge program. Mark Tomarchio – winner of the 2019 Futures Challenge University of Southern Queensland Industry considerations for truck stability at roundabouts The three highlights of the conference for me were: discussing my project with experienced

engineers and receiving genuine interest and acknowledgement for my work (which I spent a year working on), meeting lots of new contacts and attending genuinely interesting and inspiring presentations and finally the Gala dinner! I would definitely recommend the Futures Challenge to other students. It is a great experience and I encourage all who get the opportunity to challenge themselves and develop their communication and networking skills. I gained valuable insights into real-world issues, and innovative solutions that experienced engineering professionals are dealing with on a day-today basis around the state.

Ballast is a rock aggregate that forms one of the main layers of the train track structure. The voids present in the ballast provide drainage and lateral support to the track and allow for the load of the train to be dispersed over a large area. On the journey from mine to port, coal falls off the wagons and fills the voids in the ballast. As the voids become increasingly ‘fouled’, the ballast’s ability to drain and provide a stable foundation is reduced.


This ultimately becomes the root cause of a number of track geometry issues and formation failures (due to the poor drainage) hence leading to reactive maintenance efforts as opposed to preventative maintenance efforts from Aurizon. A preventative maintenance program would allow for increased productivity and capacity of the network as there would be less closures and speed restrictions due to coal fouling related issues. Currently, ground penetrating radar (GPR) is used as a non-intrusive means to determine the extent and severity of ballast contamination. This project proposes a ‘rain gauge’ type device that is installed into track to enable quantification of external fouling sources in order to complement, validate and supplement GPR data and establish fouling rates.



1 – Design, Approve and Construct the ‘rain gauge’ type containers for implementation into the track profile. 2 – Implement containers into pre-determined locations around the Stanwell Power Station Balloon Loop 3 – Analyze data to determine what locations have accelerated rates of fouling 4 – Compare fouling data gathered to existing fouling information 5 – Propose how the project can be further utilized and refined to aid Aurizon’s understanding of the track asset

Figure 5: Locations 1 and 2


The following conclusions could be drawn based on the experimental data obtained: - Comparing data from locations 1 and 2 showed that the containers placed closest to mainline track fouled at a higher rate than the containers placed in the middle and far side of the sleeper bay. Demonstrating that trains travelling past Stanwell to the port are also contributing to fouling in this location and not solely the trains entering/departing the Balloon Loop. - The fouling experienced in locations 3 and 4 was exceptionally slow and consistent across the left, middle and right of the track profile. - It was expected that locations 3 and 4 experienced low fouling rates as that particular section of track is straight, has good track geometry, is not located near any points and only experiences loaded rail traffic. Suggesting that loaded trains do not contribute as much to the fouling experienced as empty trains. - Locations 5 and 6 fouled at an extremely high rate, highlighting that the unloading techniques of the wagons are responsible for a large majority of the fouling right after the unloader. - On average, a majority of the fouling experienced at locations 5 and 6 were in the middle container. This shows that the Kwik-Drop Doors underneath the wagons are leaking residual coal onto the track. - In this investigation, it was found that empty trains foul at a much higher rate than loaded trains, meaning that the coal unloading practices are contributing a significant amount to the fouling experienced across the network. Figure 6: Container Layout at Location 5


From the data that was gathered, the following recommendations were drawn: - Results suggest that the unloading practices of the coal wagons foul the track directly after the unloader at a high rate, therefore to further diagnose the source of fouling it would be beneficial to install the containers at the mine loader to determine if more fouling is experienced during the loading process or unloading process. - Implement the containers around other assets such as bridges, level crossings and different types of turnouts to determine where the coal is falling off the wagons at these fixed points. - Conduct a sieve analysis on the samples that have been collected to further diagnose the source of fouling from the wagons (leakage through doors, parasitic coal on sills, shear plates, and bogies of the wagon) as the particle sizes will help identify where the coal is falling from the wagon.

During underground mining ore is removed from the ground, producing large voids. These voids are backfilled to ensure regional stability during blasting and excavation of the nearby orebodies. The fine grained backfills are placed in the mine voids in the form of slurry so that they can be transported through pipelines and boreholes over a large distance. A small dosage of a pozzolanic binder is added to the backfill to enhance the strength. Portland cement (GPC) is the most common binder, but contributes significantly to cost, in the order of 8 to 15% of the total mining budget. GPC production releases significant quantities of carbon dioxide and other greenhouse gases into the atmosphere.

METHODOLOGY Utilising paste fill tailings from George Fisher Mine (GFM), Mt Isa at 74% solid content, 27 mix designs were trialled with different binder material: • 40% GPC & 60% Slag • 75% GPC & 25% Fly Ash • 100% GPC The percent mass of each binder mix: • 3%, 5% and 7%.


To determine the strength of the mixes unconfined compressive strength (UCS) tests and indirect tensile strength (ITS) tests were conducted at 7, 14, 28 and 56 days of curing. With flow characteristics evaluated through the use of viscometer. Scanning electron microscope (SEM) and X-ray powder diffraction (XRD) were utilized to determine the grain shape and chemical composition/mineralogy of the GFM tailings

Mix design of paste backfill for underground mining I would recommend the Futures Challenge experience to other students as it provides an opportunity to see the theoretical and technical skills taught at university put into practice to solve everyday problems. The highlight of the conference for me was getting the opportunity to present my thesis. Although it was a nerveracking experience, it allowed me to practice my public speaking skills and speak with experienced professionals about my topic. The feedback was invaluable. From engaging and networking with experienced engineering professionals at the conference, I learnt that having a good mentor during the early stages of my career will provide me with the tools for success.

Quantitative analysis of coal fouling in the Stanwell Power Station Balloon Loop A highlight was the vast number of delegates from different backgrounds who were more than happy to prove advice and guidance on my career. Another highlight were the presentations. In particular, it was extremely interesting to hear about the future of engineering and fields I'm not involved with in my current role. I would tell future student thinking of participating to throw themselves into the deep end and go for it! I am not a fan of public speaking but I gained a lot from the experience. The next time will now appear less daunting and this is a very useful skill to have. Being able to speak publicly is also a very useful skill to have in your career. After speaking to a number of experienced engineering professionals, the main thing I learnt was that diversifying throughout your career and experiencing new challenges is what ultimately makes a great engineer. Becoming a specialist in a field is important/necessary but if you are working in a team and you understand the role of each professional you work with, this will help you become a better engineer.

Design proposal for sustainable futures building at the University of Queensland. I learnt a lot more then I was expecting, primarily around the future direction of the industry and key challenges faced by professionals. By being exposed to this type of thinking, I hope it helps me to become more aware of such challenges when I’m at work and university. And one day I may have the privilege to be a part of solving them. It was rewarding to attend and to keep up to date with key industry challenges but most importantly, I enjoyed seeing a lot of familiar faces and meeting new people! I also loved being able to meet the other students undertaking the futures challenge as well. I would definitely recommend the IPWEAQ Futures Challenge to students thinking about participating - it offers a rare opportunity to practice your public speaking in a safe setting, and the opportunity to network with other students and professionals that you might end up working with some day!

Improved theory for the design of highspeed roundabouts to suit heavy vehicles School of Engineering and Surveying Author: Mark Tomarchio Bachelor of Engineering (Honours) (Civil) Supervisor: Dr Soma Somasundaraswaran, USQ

Project Aims & Objectives

• Analyse and evaluate the commonly available standards and guidelines for high-speed roundabouts

There is a perception in the road design industry that heavy vehicles have trouble negotiating roundabouts, particularly in high-speed areas with reverse-curve approaches.

• Identify where improvement in the standards may be required

The problem in general is that there is insufficient clear and comprehensive guidance in the current Australian road design standards regarding the specific requirements for safe operation of highspeed roundabouts by heavy vehicles.

• Develop a document that clearly and comprehensively details the design standards specifically required for heavy vehicles on high speed roundabouts, in the format of a supplement to current Austroads Guide to Road Design (AGRD) standards.

Therefore the aims and objectives of this project are to:

Figure 1: Roundabout Ahead and Truck Tilting Signs. MUTCD (2018)

Methodology • The maximum coefficient of side friction tolerable by a heavy vehicle is much lower (f=0.25) than that of a car, (f=0.5) which results in larger curve radii being required to prevent heavy vehicle roll overs • Current AGRD central island radii and circulating carriageway widths are analyses and critically reviewed against specific heavy vehicle requirements

• Case study of an existing roundabout is carried out, including speed survey, simulation of travelled path, crossfall analysis, and calculated side friction factors

Figure 2: Case Study RB1 Travelled Path Analysis

Conclusions & Recommendations • Curve radii specified in current examples are insufficiently sized for heavy vehicles, resulting in side friction factors that induce instability when driven at intended speeds • Insufficient lengths of straights are specified in the current examples, which does not allow heavy vehicles to decelerate to appropriate speeds to safely negotiate the curves • Insufficient advanced warning is provided to heavy vehicle drivers to warn them that a potential hazard (ie the reverse-curves) are ahead / before the roundabout • A supplement is developed including examples of recommended approach geometry and signage

Student Reflections

Martin Luna Juncal IPWEAQ's first Student member Being an undergraduate student, finding opportunities to develop my network as an engineer and get real world experience is difficult to come by. A lot of my focus is always directed at my university study, and it’s difficult to realise that developing engineering skills extends to more than just what you study at university.

When I was presented with the opportunity to attend the IPWEAQ Annual Conference in October, it was an event that I was keenly interested in attending. I knew it was a big event and I relished the opportunity to get involved with other engineers and members of the public works community. I went in early with my younger brother, Michael, having travelled up to Brisbane from the Gold Coast, and the immediate reception was spectacular; friendly

Engineering for Public Works | December 2019

faces with a massive IPWEAQ arch really set the tone for the day. Once inside the main venue we were fortunate enough to have a bit of a look around at the different stalls that were embedded in the main hall which was set up and ready to welcome 525 delegates this year. It was quite fascinating to see a range of different companies and boards from a very broad range of public works and engineering disciplines. I took this opportunity to speak to a few of the people at the stalls


Year, Marita Cheng. She simply inspired the room with her efforts to promote women in STEM, and her story about overcoming adversity was simply spectacular. Marita highlighted just how important robotics and technology in general can be to our lives, and just how vital a simple vision can be to success. and learn about some innovative designs that they were developing, ranging from new, lightweight, cheap composites to cold-pour asphalt. Really, there were so many different companies that it’d be hard to not find something that’s interesting or applicable to undergraduate students. After this introduction session however, the real highlights of the annual conference began. Kicking off the day, the Brisbane City Council Lord Mayor, Adrian Schrinner, began proceedings by sharing his vision for the growth of the region and the significance of continuing to invest in developing our regional economy. This keynote was enough on its own to ensure that I was going to enjoy the day, but it was followed up with another incredible speech by the 2012 Young Australian of the

After the two keynotes, morning tea was served, where I took the opportunity to go around and talk to more of the people behind the stalls that were offered at the event. Again, it was great to see the hard work and innovation that is being contributed to Queensland by the public works and engineering firms. This was followed by even more brilliant papers and an insightful panel discussion relating to planning in Australia for the year 2050, including the challenges, hurdles and opportunities that we have as a nation to grow and really develop, based on our strengths and core values. After another networking packed lunch break, the conference was split into several streams. As a student keen on water studies, I went along to the ‘Delivering Surface Water Solutions’ stream. This was a particularly interesting


session covering some of the typical water topics, such as rainfall modelling, flood mapping and mitigation; but also some interesting and unconventional spins, such as using waterways as a social aspect, rather than solely as a means to transport water throughout a city. Finally, towards the end of the day, there were even more amazing talks in the main room, where important topics such as future innovations for road networks and traffic management challenges were discussed. Fittingly for me, the day ended with student presentations as part of the IPWEAQ Futures Challenge, which really summarised the experience for me: it was about learning, networking and sharing. I really think that I was able to come away from the conference with some more experience about critical and key issues that future engineers such as myself will face. Overall, it was an event that I would love to recommend to all undergraduate and graduate engineers. Experience and networking is paramount in our field, and events like this are the perfect opportunity for young engineers to really get involved and network as well as learn from experienced members in the region.

the great debate

(Logan City Council) proved that, while they may not have been convincing on the question of adaptability (according to delegates), they were well prepared to undermine their opposition’s credibility.

Rural/regional engineers are more adaptable than their city counterparts A highlight of the IPWEAQ Annual Conference each year is the Great Debate which wraps up the final day of the conference program. This is an entertaining session featuring plenty of humour, cheap shots and some key points and issues are also addressed. Both teams agreed on one point - engineers from anywhere are innately flexible and capable of managing and resolving multiple issues simultaneously. But who are more adaptable? Engineers in the city or engineers in rural and regional areas?

The winners this year, voted by delegates via the conference app, was the Affirmative team of Glenda Kirk (Mareeba Shire Council), Ben Ash (George Bourne & Associates) and Andrew Johnson (Somerset Regional Council). Perhaps delegates were persuaded by the Affirmative team’s demonstrations of how they deal with every possibility always equipped with the right tools at the right time. Not to be outdone, the Negative team comprising Joe Bannan (Brisbane City Council), Jessica Kahl (Aurecon) and Paul Wilson

The Great Debate, introduced in 2016 has now been won twice by the Affirmative team and twice by the Negative team.

Applying safe systems principles to priority crossing for pedestrian and cycle paths


Prudence Oswin Sidelines Traffic Abstract: Safe systems principles have been incorporated into technical guidance and practical examples of cycling infrastructure in Queensland. Providing crossings at side roads that give pedestrians and bicycle riders priority over vehicles is one way of ensuring that shared pathways are more direct and comfortable for users. However, the key concern of many practitioners and users is whether these facilities are safe. Results of observational studies into existing raised priority crossings were used to identify key design attributes for priority crossings on side roads. The design guidance was also tested against safe systems principles to ensure that facilities allow for human error but are unlikely to result in serious injury or harm to users. The results of this work demonstrate that priority crossing treatments can be developed, consistent with safe systems principles to deliver

safe, convenient and more direct cycling facilities where more users are comfortable to use shared pathways. Where pathway users are given priority across a road using regulatory Give Way or Stop signs and line marking, it is referred to as a priority crossing (TMR, 2019) (see Figure 1). Providing raised crossings at side roads that give pedestrians and bicycle riders priority over vehicles is one way of ensuring that shared pathways are more direct and comfortable for

users. However, the key concern of many practitioners is whether these facilities are safe. The Safe Systems philosophy for road safety has been adopted by Queensland and Australian Governments in their road safety strategies published in 2015 and 2011 respectively (TMR, 2019; Australian Transport Council, 2011). Despite this, the most recent review of the National Road Safety Strategy found that “the Safe System approach has been adopted but not ingrained or

General Safe Systems Description


Single function of roads as through, distributor, or access road in a hierarchically structured road network

Path facility has same priority as parallel road, such that cyclists are attracted onto the separated facility, and not delayed at lower order roads.


Equality in speed between users sharing space, and mass and medium and high speeds

Equitable speeds between path users and vehicles at crossing point (<30km/h). This allows users to see each other and opens up time to react and avoid crashes.


Road environment and road user behaviour that support road user expectations through consistency and continuity in road design

Areas where vulnerable road users and vehicles come into conflict are clearly delineated. Signage and line marking used to clearly indicate priority.

State of awareness

Ability for network user to assess one’s capability to handle the task

Unlicensed users not relied upon to avoid conflicts and make complex decisions. Road design reinforces responsibility of licensed road users to give way to pedestrians and bike riders at side roads.


Injury limitation through a forgiving road environment and anticipation of road user behaviour

Motor vehicle speeds reduced such that, consequences of crash probably not serious or fatal. Aim to provide vehicle speeds of 20km/hr at pedestrian crossings.

mainstreamed within government business by federal, state, territory or local governments.” (2019 DTCRD) The central premise of the Safe Systems philosophy to road safety is that people should not be killed or seriously injured as result of traffic crashes (Austroads, 2015). It also recognises that people will make mistakes and puts an onus onto designers to create infrastructure that is forgiving to these mistakes, so that crashes do not result in serious injuries or fatalities. There are 5 key principles to Safe Systems philosophy. They provide a framework that can be used to assess whether infrastructure is consistent with the philosophy. They are broadly described as functionality, homogeneity, predictability, state of awareness and forgivingness. Table 1, Column 2 describes how the Safe Systems Principles apply to planning for all users in traffic networks as described in Austroads (2015). Column 2 describes how the principles can be more specifically applied to protect vulnerable road users at side roads. To assess whether environments are ‘forgiving’, critical impact speeds are used. Critical impact speeds have been calculated for different crash types and users (Austroadsb, 2015). They represent the speed of a bullet vehicle in a crash which results in a 10% chance of severe injuries or death. For crashes involving pedestrians (and cyclists), this speed is approximately 20km/hr. For adjacent direction crashes the critical impact speeds is 30km/ hr and for rear-end crashes it is 55km/hr (Austroadsb, 2015).

The preferred attributes of raised priority crossings are defined in the TMR Guideline, Raised priority crossings for pedestrian and cycle paths (TMR, 2019). These attributes were developed following observational research on existing facilities, and to be consistent with the Safe Systems framework and critical impact speeds. A general overview of the attributes and their links to Safe Systems is provided in Figure 2. The Safe Systems principles provide an effective framework for designing infrastructure to avoid crashes that might result in serious injuries or fatalities. Understanding critical impact speeds for the crash types that might occur, and uses involved, is an important component of the assessment.

Kirsty Bilton is a traffic and transport engineer with over 15 years’ experience in the private and public sector including work in the US. Kirsty has experience in all facets of traffic engineering and transport planning. Kirsty has a Bachelor of Electrical and Computer Systems Engineering and Graduate Certificate in Transport and Traffic and is a RPEQ.

EPW: Please tell us about yourself: where are you from, what are your interests, what makes you tick? KB: I was born in Perth, Western Australia and spent the first 10 years of my life moving every couple of years as my father was in the RAAF. We moved to Brisbane in 1989 and my parents are still in that house. I think that because of this change as a child, I have

Engineering for Public Works | December 2019

developed a love of travel and have lived interstate and overseas (Japan and the United States of America) for extended periods of time as an adult. Thanks to family connections with North Queensland, I have been a passionate North Queensland Cowboys supporter since the beginning in 1995. I was fortunate to have been able to attend the


2015 Grand Final when they beat the Broncos in Sydney. I can’t wait to attend a game in the new stadium in Townsville sometime in 2020. EPW: Please summarise your career to date in your own words. KB: I got my start in traffic and transport in Melbourne in 2000 working for Transurban and Transfield on the CityLink road network. When I returned to Brisbane, I worked for Brisbane City Council for a couple of years in the Traffic Management Centre, and also did a couple of stints of vacation employment and completed my thesis with the Road Use Management team while I finished my degree and then headed overseas for three years. I nearly didn’t come back to engineering. My time overseas opened up a can of wanderlust and I seriously looked into becoming a travel agent. Instead I found a graduate traffic engineering role at Cardno Eppell Olsen in late 2005. At Cardno, I was involved in a broad range of traffic and transport work including traffic impact assessments for large shopping centre expansions and a number of projects for the resource sector in both the Bowen and Surat Basins. I also undertook a 10 month work exchange to the United States where I worked as a traffic analyst for Kittelson and Associates. In 2011, I made the move to Ipswich City Council (ICC) as the Traffic Signal Engineer and over time ended up being involved in every aspect of traffic and transport from signs and lines, to development application reviews and strategic transport planning.

I value the time at ICC because I was able to obtain a detailed understanding the range of traffic engineering and transport planning in a local government context. I feel that it would have been much harder to get the same level of exposure and experience at a larger Council. In April 2015, I made the move to the City of Gold Coast to strengthen my knowledge and experience in traffic signals and ITS. In early 2016, an opportunity

came up for me to move into the City’s Commonwealth Games team where I was initially a part of the Integration team and later moved into the Network Operation and Traffic Management areas. After the completion of the Games I started working for Brisbane City Council in the Congestion Reduction Unit as a Traffic Network Engineer, responsible for the efficient operation of the road network, largely through the operation of traffic signals.

Engineering for Public Works | December 2019


In September 2019, I started as the Acting Maintenance Delivery Manager in the Traffic Network Services team. I am responsible for leading a team of about 20 people who maintain and deliver the traffic signal, ITS, CCTV, fibre and network infrastructure and services on a 24/7 basis. EPW: What’s been your most significant career highlight to date? KB: Being involved in the planning and delivery of the 2018 Gold Coast Commonwealth Games (GC2018) Road Events (triathlon, race walk, road cycling and marathon) and the Queens Baton Relay was an incredible opportunity that will be difficult for me to top. As Council’s Traffic Manager for Road Events and Queens Baton Relay, I was responsible for providing input into the preferred routes, determining the network impacts of the road closures and identifying diversion routes, overseeing the development of and implementation of the traffic management overlay. I also got to ride in the front of a Police car for the four days of Queens Baton Relay, which was lots of fun. EPW: What do you find most satisfying about working as an engineer in public works? KB: One of the appeals of the traffic and transport sector is that the work is tangible and the outcomes of our work can be see in relatively short timeframes. It’s very easy to explain to people the work that I do. In public works this is even more visible, and you know very quickly the impacts of the work you have done, for better or for worse. I really enjoy travelling

around a city and knowing that I was involved in making things better and often safer for the broader community. EPW: Have you faced any particular challenges as a woman in public works engineering? And if so, how do you overcome them? KB: Many of the challenges that apply to being a woman in engineering apply regardless of whether you are in the public or private sector. Having said that, I find that when I am working in more operational areas (like my current role) then the limited number of women is far more noticeable. This is something that I would love to see changed.

Engineering for Public Works | December 2019

There are some great programs being done to get more girls and young women interested in STEM at the primary and secondary school level that we will hopefully start to see the benefits of in the coming years. In the shorter term, programs to encourage more women to consider moving into leadership positions may help stem the flow of women leaving the industry mid-career and provide younger women with more examples of women in leadership positions that can act as role models. The benefits that the public sector offers such as more flexible working conditions could also be promoted more to encourage


some of these women to shift from the private to the public sector. EPW: What do you appreciate most about your involvement with IPWEAQ? KB: I appreciate how IPWEAQ provides a forum for collaboration between the different agencies and organisations involved in delivering public works engineering. The different activities like conferences, training and publications allows people from across the state an opportunity to share what work they are doing which can result in the promotion and roll out of some great ideas and projects across Queensland. EPW: What would be the one piece of advice you would give to others early in their career? KB: Don’t be afraid to ask questions, try new things and

don’t be afraid to make mistakes. We all learn and grow through being outside of our comfort zone, and while this is difficult, it is so worth it. Also take your time to work out what area of engineering you enjoy and if you are not enjoying what you are doing look for opportunities in other areas. While my degree is in Electrical Engineering, for much of my career I have worked with civil engineers in the traffic and transport area. One advantage of being an engineer is that many of the skills are transferrable between disciplines. EPW: Do you have any particular advice you would offer to young women thinking of a career in public works engineering? KB: Do it. Public works engineering is full of diverse opportunities and is incredibly fulfilling. Working in

the public sector offers you the ability to deliver work that will make a difference to the lives of people in the community that you live and work in which brings meaning to the work we do. Don’t be afraid to be yourself, especially if you are in the minority as a female engineer. This allows you to bring new perspectives to a workplace and ways of solving problems which are critical for ensuring that the outcomes we deliver are relevant to the broader community. Reach out to other women in industry to share experiences, ask questions and seek advice. There are some incredible female leaders in public works engineering that I have found are very generous with their time and are more than happy to help others out.

intuition, infrastructure and overcoming bias


James Thorne WSP, Christchurch, New Zealand Masters of Engineering, University of Canterbury, New Zealand Dr Eric Scheepbouwer Director of Construction Management, University of Canterbury, New Zealand Abstract: Who can we trust to make the strategic infrastructure decisions that our communities desperately need? Wisdom tells us to first look to the industry experts. But how well are we cultivating this intuitive expert knowledge? Does the decision-making process hold up to scrutiny and is it conducted in a framework of continuous improvement? This article is adapted from the 2019 winning IPWEA NZ Hynds Paper of the Year and showcases the results of James’s master's thesis research examining "Intuitive Decision-making for Wastewater Pipe Networks". 1 Introduction The principles of integrated asset

management are well understood and implemented in our region. New Zealand and Australian local governments have led the way through the development and publication of the International Infrastructure Management Manual (IIMM) which promotes a Total Asset Management Process. The IIMM forms an important benchmark for integrated asset management systems around the world and is regularly referenced in academic papers. The strength of the IIMM is the focus on developing integrated organisational strategies and having a decision-making process that is aligned with the overall plan and takes into account all of the various stakeholders. There are numerous standards, guidelines, computational models and support tools that assist the development of integrated asset management frameworks by describing the decisionmaking process from a rational perspective. For example, capital expenditure strategies may focus on the “hard” network data such as pipe size, age, material, and perhaps camera footage from inside the pipes. Reliance on this “hard” data for decision-

Engineering for Public Works | December 2019

making is problematic due to the complexity of wastewater networks and uncertainty regarding the relationships between data, performance and causality. Poor data quality is another reason to be wary of deterministic decisions based on “hard” data. In contrast to the numerous support tools using “hard” data, little formal guidance is available on how to appropriate operational deficiencies into the decision process. And potentially more significant, is the omission of formal methods of including intangible factors such as political, economic, environmental and social influences. It is often these intangible influences that have the greatest bearing on capital expenditure for wastewater networks. A next step in wastewater asset management, perhaps, is to provide decision-makers guidance for practically implementing a process of weighing up intangible and often competing influences to make transparent and robust decisions. Investment decisions for wastewater networks are complex and take into account a broad


Figure 1 First level of decision tree

system of influences. The wide range of influences supports the idea that wastewater networks are complex and deterministic decisions based on “hard” data alone are not appropriate. Instead, decisions require the use of “intuition” to weigh up the various factors in order to make a best fit decision so that investment and construction actions can proceed. Good intuitive decisions rely on the relevant knowledge and experience of the decisionmaker(s) and also on processes that reflect the complexity of the system. Current research and guidance for intuitive decisionmaking is not well developed, thereby leaving local governments potentially exposed to risks of bad decisions. This study addresses the problem by investigating intuitive decisionmaking processes and develops a new methodology to quantify and document decision data. 2 Intuitive decision-making 2.1 What’s so complex about wastewater networks?

The complex nature of wastewater networks comprises the following categories: Socio technical The influences are a mix of the technical (pipe attributes, hydraulics, loading demands etc.) and social (financial impacts, stakeholders, public safety, environmental protection, political interests and regulation). Network complexity There is an important connectedness where each individual element is part of the wider system and there is an inherent interdependence. As pipe networks grow in size and number, the complexity of the connectedness also grows. Unknown causality Causation is the “cause and effect” relationship where a network performance state can be shown to be the result of a particular characteristic. Due to the complexity of the network there is a high degree of uncertainty as to what characteristics caused a particular issue of failure.

Missing data Local Governments struggle with asset data that is either altogether missing, incomplete or unreliable. This issue is confounded by the nature of wastewater networks being buried underground assets, effectively invisible. This data issue is a barrier to the prediction of outcomes using calculative models. 2.2 Why intuition? Psychologist Daniel Kahneman describes two distinct modes of thinking: System 1 and System 2. System 1 operates automatically and quickly, with little effort and without the requirement of voluntary concentration. This mode draws on relevant experience, knowledge and “gut”, and is fundamentally important for intuitive decision-making. System 2 allocates attention to effortful mental activities, tracing mathematical and logical solutions to the task at hand. This mode is relied upon heavily when adopting rational decision-making processes.

Engineering for Public Works | December 2019


Figure 2 Factors to determine overflow risk

The field of engineering has a practical outlook and could be viewed as the application of science and mathematics to provide some societal need. It follows that these scientific and mathematic fundamentals require that engineers rely heavily upon the System 2 mode of thinking and rational decision-making. Rational decision-making works when problems are well defined and can be broken down so that the mathematical System 2 approach can be applied. However, System 1 thinking is more useful where problems grow increasingly large, complex and less well understood. The complexities of wastewater networks provides an opportunity for System 1 intuitive thinking to shine.

2.3 Intuitive pitfalls There are however some associated pitfalls to understand when using expert intuition. Transparency There is a transparency issue as decision-makers use their own expert knowledge to jump from A to E in a decision without necessarily being able to articulate or document the skipped calculations of B, C and D. Bias Unconscious bias is present when using intuition and undermines decisions accuracy. Bias can appear in; anchoring, confirmation bias, groupthink, information bias, and loss aversion. Institutional knowledge

Engineering for Public Works | December 2019

Knowledge is gained through experience and our senior expert staff have accumulated great insight. However, our aging society presents a risk of losing intuitive expertise and institutional knowledge of retiring staff. One way of overcoming pitfalls and bias is by documenting the intuitive decision-making process. This gives a reference point; a chance to audit and challenge assumptions, and provides an opportunity for learning so that intuitive decisions can be improved over time. 3 Industry survey to document intuition 3.1 The decision system model The developed method focusses on relevant factors and their levels


Figure 3 Example industry survey question

of importance. This importance weighting or “significance” of factors comes from an industry survey of wastewater network experts. The context question for the decision model is: “which pipe should I replace/repair?” The decision tree used to answer this question considers how each factor contributes to the overall network performance. The tree branches down into the five main network failure categories and includes factors that contribute to the likelihood or consequence of each failure risk. 3.2 Quantitative assessment For each factor the various factor scores and significance weightings can be used to quantify the impact to network performance. Factor score A factor score of 5 is bad and a

factor score of 1 is good. “Bad” is also synonymous with high risk and “good” with low risk.

was taken by 43 participants between 7 February 2017 and 27 February 2017.

Significance weighting The significance of each factor is determined from the industry survey. The survey frames the questions from the perspective of a wastewater network asset manager tasked with having to determine which pipes in their network to repair or replace. The weightings are quantified using a 1-5 Likert-type scale.

4 Results

Survey participation The survey was distributed online and circulated to Water New Zealand and the Institute of Public Works Engineers of Australasia, with some direct requests to Council and engineering consultant contacts. Participants who were experienced in wastewater network renewal decisions or investigations were asked to self-select. The survey

Typically the significance scores from the experts were in the 3 – 4 range. A “Top 2 Box” calculation is useful for Likert scale survey methods. Top 2 Box results are the percentage of all results on the 1 – 5 scale that were reported as 4 or 5, that is, Very Significant or Extremely Significant. These results provide the input for the significance weighting for each of the factors. Further analysis was done to determine how much of an influence each factor has on the overall network performance score. This was conducted by creating a model where each factor score is combined with its significance weighting and connected together using the format of the overarching decision tree.

Engineering for Public Works | December 2019


Unsurprisingly, those factors appearing near the top of the decision tree had more of an impact on the overall network performance compared with those that appear as sub factors at lower levels of the tree. The impact of each factor and the ranking is provided in the full paper.

to refine and simplify the decision tree model to only use the highest scoring factors.

5 Conclusions

Targeted effort for setting 1 to 5 factor score categories and thresholds Similar logic also applies to the task of setting the 1 to 5 factor score thresholds. The knowledge of which factors are most significant can help to hone the effort applied when coming up with the 1 to 5 factor score categories and thresholds.

The industry survey and overall method of documenting intuition provides insight into several benefits: 5.2 Benefits Provides prioritisation scores The method provides prioritisation scores once the significance weights are combined with the factor scores. The method is adapted from existing techniques and theories and provides a workable solution. Documenting the prioritisation scores allows improvement of intuitive decisionmaking over time. Identification of the factors to include or not include in decision-making The Top 2 Box results provide clear indication of which factors are significant or not for the renewal prioritisation decision. These observations can be used

Targeted data collection The significance weightings also show the most important factors to concentrate on for data collection.

Qualitative decision-making and prioritisation Numeric representation of a decision tree may be beyond what an asset manager is capable of at a given point in time but nevertheless the significance weightings could still be referred to. Using a qualitative high/med/ low significance would provide useful prioritisation. Testing the decision tree structure and hierarchy The process of completing the survey and applying the method provides a chance to analyse the

Engineering for Public Works | December 2019

results and then go back and challenge what was originally assumed as the appropriate decision tree. Can be applied across a network Once set up, the method can be applied at scale allowing the computational benefit of process repetition to apply scoring across the network. Provides a documentation trail The documentation allows auditing of the decision quality and also gives a starting point for refining the method over time to facilitate continuous improvement. Links individual factors with ultimate decision outcome For each factor it is possible to see which other factors are influenced by it and also to see how those factors ultimately affect the decision outcome. Used as a shortlist It may be that the asset manager wishes to retain the autonomy of the ultimate decision-making, and even in this case the method provides assistance. This method could be used to shortlist pipes as candidates for action still allowing room for the asset manager to apply their own expert intuition at the end of the process.

Places of Refuge – Building Resilience through Coastal Engineering                                    Places of Refuge – Building Resilience through Coastal Engineering By Lana Maki (Peak Services) and Simon Kochanek (Bligh Tanner) Mornington Island is an extremely unique part of Queensland with a strong cultural heritage and proud people who are intimately connected with their place and their heritage. It is a remote island situated in the Gulf of Carpentaria. Many challenges confront the community such as isolation, access to goods and services and exposure to natural disasters. All aspects of life on the island are impacted by these factors and many more, that would be hard for many on the mainland to fully appreciate. The only way to and from the island is by air, which adds an extreme layer to the fundraising efforts of the local premiership rugby league team and financially impacts all who live and work on Mornington Island in terms of accessing specialist healthcare and seeking shelter from seasonal weather events. Every item on the island must be barged across once a week, there is no hardware store or chemist. Mornington Shire Council (Council) takes a lead role in supply of

essential services to the community with much determination and ingenuity. Bakery, hairdressing, civil services, airport, service station, mechanical workshop, concrete batching plant, accommodation are but a few of the services Council provides to the community and visitors. This is provided at a minimal margin to ensure these services are affordable for a community already fiscally constrained due to a high cost of living and limited employment opportunities. The Mayor, Elected Members, CEO and Council Executives advocate on behalf of the community for continuous

Engineering for Public Works | December 2019

improvement to liveability and opportunities on the island. Peak Services (Peak) have been assisting Council in writing grant applications to achieve their goals. The community is in desperate need of a cyclone shelter as the island is threatened several times a year and with no shelter, many people must be flown off the island at great expense to Council and the community. Council have been advocating for some time across all tiers of government for assistance to build an integrated hub to house many essential services, a training facility and


event centre that can double as a maintainable cyclone shelter, so far to no avail. In desperation and with inherited degraded assets, council looked at other ways they might help protect their community and successfully applied for a small NDRP grant. This grant was to investigate the suitability of Council owned assets to withstand cyclones and determine which buildings could be readily engineered to meet the required resilience to cyclonic wind speeds for the region. Peak on Council’s behalf engaged engineering consultants Bligh Tanner to undertake the works of inspecting over 100 buildings, over a five-day period to then produce a 280-page recommendation report. This report provided the basis for utilising Works for Queensland (W4Q) funding for a project aptly named ‘Places of Refuge’. Bligh Tanner worked closely with Peak’s Project Manager Lana Maki and the Council to identify building structural deficiencies and recommend critical repairs to existing buildings on the island. The region is regularly exposed to cyclones which necessitates

the evacuation of members of the community, who do not have access to cyclone resistant buildings. The lack of a cyclone shelter on the island places all on the island in a vulnerable position each cyclone season. The project initially involved the assessment of the buildings to resist the cyclonic winds that the region is regularly exposed to. The subsequent phases of the project involved the development of engineering solutions to repair and improve the buildings’ ability to resist cyclonic winds. Simon Kochanek, one of Bligh Tanners Principal Engineers who has extensive experience in the

remediation of existing structures completed structural inspections and audits of more than 100 buildings on Mornington Island at the end of 2018. The investigation works included the inspection of all accessible components of the buildings, including subfloors and roof spaces. The inspection works identified numerous existing buildings with significant deficiencies making them unsafe if exposed to even moderate wind speeds. Some of the building deficiencies identified included: • Limited or inadequate roof tie down. • Inadequate bracing, or structure for lateral stability

Engineering for Public Works | December 2019


disuse for 10 years and is being refurbished and reopened. The engineering solution will not only equip the building with cyclonic tie down suitable for the region, it will have the added benefit of making the building more secure outside of business hours and support a modern open airy interior that connects with the outdoor dining areas when operating as a tavern restaurant.

• Inadequate tiedown to prevent overturning or uplift. • Structures with inadequate member sizes to resist impose wind actions • Corrosion, decay or termite damage which reduced the capacity of members to resist required actions. • Previous modifications resulting in the removal of structural members required to resist the imposed wind actions. The engineering audits allowed the buildings to be rated and categorised to determine their likely ability to resist cyclonic winds with recommendations for repairs and strengthening to improve capacity. Bligh Tanner senior staff used their experience in working in remote areas and communities to develop practical engineering solutions to repair the structural deficiencies identified. Solutions were tailored to suit the local community, accessible materials, and skills available on the island. ‘Places of Refuge’ seeks to restrain buildings that are not securely tied down to prevent them becoming airborne projectiles, but more importantly provides some surety

for Council that several buildings could be used for shelter in the event of a moderate cyclone. Whilst not providing the level of protection a cyclone shelter would, this project will have a dramatic impact on the island and the community. The project will reduce Council’s financial risk during the cyclone season, allowing funds to be spent on essential services and will enable Council to retain staff due to the high level of risk posed from cyclones without access to suitably engineered buildings. The most important benefit will be the safety and retention of people on the island to help recover and make safe for the community in the aftermath of a natural disaster. It has been several weeks after recent events before it has been possible to return clean up crews to the island. Peak have been providing ongoing project management services to Council to assist with several grant funded projects, including this W4Q ‘Places of Refuge’ project and further engaged Bligh Tanner’s expertise to solve complex and multi-layered engineering challenges. One such challenge has been the re-engineering of a large old tavern that has been in

The key upgrade that makes this all possible is the introduction of cyclone shutters to all external openings. The shutters when open provide a clear unobstructed view to the outdoors which is currently completely obscured by permanent steel framing and boarding. The current steel and boarding are not proving secure as the building has been broken into several times. The cyclone shutters will be tamper-proof and resistant to break-ins. Most importantly the shutters will exclude wind during moderate cyclones which has enabled the building to be cost effectively tied-down due to the reduction in internal pressures. Bligh Tanner responded quickly to address remediation requirements to allow repair works to be completed prior to the 2019/2020 cyclone season. The engineering repairs and solutions that were developed were detailed to allow for flexibility with installation and cost effective to install, to ensure the local community could undertake as much remediation works as possible with the limited funds available. Peak Services and Bligh Tanner have been delighted to be part of the project and to work closely with this remote community to deliver safer buildings for Mornington Island.



In our recent IPWEAQ competition, four lucky people won conference tickets valued at $2,295 each to the Australian Road Research Board (ARRB) Smart Pavements Now Conference in Melbourne in September. Steve Forbes, BernieAnne Freeman, Leon Surawski and James Tayler attended the three-day masterclass event which was aimed at pavement industry professionals, covering topics such as Pavement Design and Smart Materials, Asset Measurement Devices, and Sustainability and Safety.

Bernie-Anne Freeman Senior Engineer (Civil), Downs South West Region Program Delivery And Operations Branch, Infrastructure Management and Delivery Division, TRM Thanks to IPWEAQ and ARRB, Bernie-Anne Freeman attended the Smart Pavements Now Masterclass,

at the National Transport Research Centre in September 2019. The three-day workshop focused on all things Pavements, including innovative materials and design, asset management, sustainability and safety aspects. Delegates from international, state and local road authorities, contractors and pavement consultants took part in the masterclass. The masterclass showcased the range of initiatives the Australia Road Research Board (ARRB) are involved with across Australia, including Austroads Guides, testing and asset management devices, and partnerships with

Five Fun Facts, quoted from Smart Pavements Now Conference Research focus: Reclaimed Asphalt Pavements (RAP), Crumb Rubber, Glass and Plastics are the four main innovative pavement materials being researched and utilised. 1. A ustralia is 14th on the global ladder for Connected Automated Vehicles (CAV) readiness (Data source: KPMG) 2. 907 000km of roads connect Australians – of which 63% is unsealed 3. Within the transport industry, 85% of Greenhouse Gas emissions is due to the road transportation sector, making the industry the 2nd largest contributor to emissions in QLD. 4. I n Australia, 56 million equivalent passenger unit (EPU) waster tyres produced in 2017. This equates to about 2 tyres per person. Currently, this is mostly exported, stockpiled or landfilled. state authorities like QLD Transport & Main Roads through NACoE and WA Main Roads through WARRIP. Presenters kept the delegates engaged through use of menti.com to allow interactive sessions from delegates smartphones. Day One: Pavement Design The ARRB office and laboratories are based in the National Transport Research Centre. Delegates were able to tour the laboratories to see where testing is undertaken and observe tests such as

Austrack (slab compactor and wheel tracker), which is used to measure permanent deformation characteristics in unbound granular materials. Asphalt testing of various materials such as highmodulus asphalt, crumb rubber in asphalt and recycled asphalt (using Glass and RAP) were visible in the laboratory. From the recycled material presentations, it is evident that having state authority and national specification are key to the mainstream use of these materials. The use of recycled materials in pavements varies between road authorities within Australia and globally, with the USA allowing up to 15% of recycled glass in asphalt pavements, compared to much lower thresholds in Australia (up to 2.5% in NSW). Recycled glass used in asphalt pavements passes the 4.75mm sieve. Crumb rubber currently used within Australia is solely truck tyres, which have a greater natural rubber and metal content then car tyres. Car tyres are not currently used due to truck tyres suppling current demands of crumb rubber, having less rubber content and requiring a separate processing plant produce crumb rubber from car types, due to the much higher presence of nylon fabric compared to truck tyres. Use of crumb rubber in sprayed seals is well established in Australia, with crumb rubber in asphalts emerging. With increased demand of crumb rubber in sealing, asphalts and other technologies, use of car tyres for production of crumb rubber is viable given suitable processing. Reclaimed asphalt pavement (RAP) is currently used in mixes up to 15% (by mass) in Australia, and current investigations are

Engineering for Public Works | December 2019

underway to explore how greater proportions of RAP can be utilised in asphalt mixes. Trials have been undertaken to see how crumb rubber asphalt would perform as RAP, and results have indicated that these pavements are also suitable for RAP. Day Two: Asset Management Devices Delegates were introduced to two data pickup vehicles, the iPAVe and the iSSAVe. Both vehicles are available for road authorities to complete data pickup of their road network, and both vehicles have travelled around Australia. The iPAVe calculates deflection, automated cracking, GPS, imaging, rutting, pavement texture and roughness. The vehicle runs at 80km/hr providing a safer data pickup mechanism. The iSSAVe collects skid resistance data primarily, as well as GPS, imaging, rutting and pavement texture and roughness. Currently, the iSSAVe collects data at 50km/hr, however testing to run at higher speeds is currently being investigated. Auditing of roads for CAV readiness is underway in Australia, with assessments of existing road infrastructure such as linemarking, signage, and other road features being surveyed in real-time. This process simulates how CAV machine vision systems work and determines the readiness of Australian roads to support this technology. Day three: Sustainability and Safety The final day of the conference focused on improving safety and sustainability of pavement treatments. Use of materials is moving away from the current linear economy, working towards a

circular economy where reuse and recycling can continuously occur. With QLD the largest carbon producing state in Australia, NACoE have assessed the effect of innovative pavement solutions on Greenhouse Gas Emissions. Emissions generated throughout the pavement lifecycle were analysed, from production of materials through to maintenance and end of life. Pavement technologies evaluated include: • High Modulus Asphalt (EME2) • Reclaimed Asphalt Pavement (RAP) • Crumb Rubber Binders (using recycled Truck tyres) • Foam Bitumen Stabilised (FBS) Pavements • Use of marginal materials (locally sourced materials where standard materials require long haul distances)

All innovative pavement solutions found an emission saving over 40-year life cycle. The model presented a 3.7% reduction in emissions through use of EME2, 5% reduction through RAP and FBS pavements, up to 17% for crumb rubber binders and up to 22.7% for locally sourced marginal materials, compared to traditional pavements. Comparatively, utilisation of electric vehicles can reduce emission by up to 45%. To find out more about some of the topics mentioned, check out Austroads, ARRB, NACoE and WARRIP publications. Thanks to IPWEAQ for the opportunity to attend the Masterclass. The topics were very relevant my work, and great to meet those who have written and worked on publications that my team and I use on a regular basis.

I thank the staff of ARRB who delivered a thought provoking and interesting masterclass.

Engineering for Public Works | December 2019


The Masterclass was held at ARRB’s new National Transport Research Centre in the Port of Melbourne. A purpose-built research centre with offices and laboratories co-located. The presenters knew the content of their presentations in great detail. I commend them on their ability to distil, months and years of research and knowledge into, one to one and half hour presentations. The subject of greatest interest to me was how local authorities may utilise waste materials, diverting them from landfill by diverting them from the waste stream and incorporating them into road pavements. There were presentations on the reuse of asphalt pavement as recycled asphalt pavement into new asphalt pavement, recycled tyres into bitumen binder and asphalt. The challenge went out on how to divert 56 million passenger equivalent tyres from landfill. Toowoomba Regional Council will use approximately 12,000 tyres in this resealing program. It is possible to incorporate waste products, tyre rubber, steel fibre and glass, into asphalt pavements while maintaining the recyclability of these asphalt pavements. Recycled Asphalt Pavement, RAP, is able to be incorporated into new asphalt pavements up to 50% of new asphalt. There is, currently, not enough RAP available to allow this level of use. Crumb rubber is able to displace other polymer additives and achieve similar performance criteria. Binders incorporating crumb rubber is more suitable for open graded asphalt than dense graded asphalt. Research on the performance of crumb rubber binders in asphalt is ongoing. Crumb rubber currently used in

ARRB’s iPAVe Survey Vehicle.

asphalt binders is derived from truck tyres that have a higher proportion of natural rubber, 65%, and 35% synthetic rubber than is present in passenger vehicle tyres that have 35% natural rubber and 65% synthetic rubber. Truck tyres are being used as they have a greater rubber content than passenger vehicle tyres. It is more difficult to separate rubber from other materials, steel and polymer fabric, contained in tyres. Toowoomba Regional Council has used a high proportion of crumb rubber binder in their

Engineering for Public Works | December 2019

reseal program last year and is continuing to use crumb rubber binder this year. The constraints of temperature and the narrow, effective window of optimum benefit for the digestion of crumb rubber were explained. The further development of intelligent compaction was interesting. The example of an experienced roller driver who was only able to achieve 60% coverage without the equipment but quickly learnt to achieve 90% coverage by


using the equipment was good. The use of the equipment has cost and quality benefits especially for new roller operators. Convincing the Department of Main Roads that this technology is able to reduce the level of testing required is likely to be a challenge. The Veta software will assist in providing the evidence for the technology to be adopted especially with side by side testing. The introduction of iPave is an interesting development because of its ability to assess pavement condition at a road’s posted speed. The machine will allow an assessment program to be conducted faster and the data provided more quickly than current methods of data acquisition. It will allow the assessment and prioritisation of needs when planning next year’s rehabilitation program. The field visit to ALF was a highlight of the masterclass combined with the explanation of how cement modified pavements react under loading confirmed why they are subject to early onset potholing. The test strip of chip sealed cement modified pavement had potholed in the same manner that I have observed

with cement modified pavements in our Region. The pavement material performs well under asphalt but not under chip seal. The upward cracking under load degrades the pavement to a noncohesive granular material after only 30,000 loading cycles. The degraded pavement is unable to withstand the shear stress of tyre loads resulting in potholing. Under asphalt the pavement is not subjected to the shear stresses and remains confined. I am looking forward to the publication of the Best Practice Guides presented by Dr Michael Moffatt. They will be of great benefit for the instruction of new and old road maintenance and construction workers. There has been no similar publication that I am familiar with in my 25 years of experience that has covered these subjects. I currently use the Main Roads Western Australia publication “The Effective Use of Plant” 1983 for instruction but that publication is becoming dated with the technology that is now available.

research and months of available reading. It is a good reference, in its fifteen parts, for the Best Practice Guides that are, as yet, unpublished. The presentation of the National Road Safety Partnership Program was good as I had attended the first webinar of the four scheduled as part of the program. The program presents the lived experience of various operators and how they have addressed their particular road safety issues. Having now attended the second webinar in the series, I have gained greater insight into the complexity that is road safety. I have been on the Safe Systems journey for thirteen years and am still learning the intricacies of how to make our road network a safer place to work. I recommend the ARRB to all road asset owners as a research organisation and repository of knowledge for road maintenance and construction and how to achieve value for money outcomes in an ever decreasing resource environment.

The presentation by Dr Tim Martin of the Austroads’ Guide to Asset Management was good, a one hour precis of many months of

Design Thinking – a strategy for engineering innovation                                    Computers and the internet have accelerated the path for engineers to advance at a scale that would have been unprecedented 30 years ago. Automation is on the rise, Artificial Intelligence (AI) is becoming a mega-trend and digitisation is already influencing the labour market’s prosperity. Combined with a more diverse workforce, engineering will not only advance to autonomous cars and affordable UberEATS via drones but to a concept we can’t imagine today. The future is here whether we’re ready or not. Technology trends such as AI have the potential to solve some of humanity’s biggest challenges in areas like transportation, healthcare, education, communication and manufacturing. And with predictive technology on the rise, our future is set to become more efficient and change will have a profound impact on how we all live, work, and play. As engineers, our designs have the potential to explore and leverage these opportunities. Through empathy and experimentation, the way we think about design can help identify some of the risks and opportunities early in the creation process. For example, ensuring AI

remains unbiased and inclusive. While the potential upside of AI is profound, there’s a need to be extra thoughtful when creating designs so that the end-result is one which is a meaningful humanity-centred solution. Steve Jobs was an innovator who was passionate about being able to “think different”– he didn’t consider design as a thing or a product; he thought of it as a practice, as a manner of thinking. He instilled this mindset in his company from the top down. “Design isn’t what it looks like and feels like,” he said. “Design is how it works.” Empathy in Design We spend our engineering careers translating human needs and desires into solutions that fulfil them — and I’m convinced: the human-centred design process demands empathy so that the solution is one which is sustainable for our end users. Empathydriven inspiration helps us understand the known parameters of the challenge and how best to approach and interpret the information on hand – and so the understanding of how we do this better is imperative to how we approach complex challenges. A tool which has proven successful in helping engineers to practice

Engineering for Public Works | December 2019

empathy, test and validate ideas is Design Thinking – a concept popularised by Stanford’s d.school and IDEO. The tool has taken the world by storm as its unique approach provides professions in the design process with useful tactics for achieving innovative processes which minimise risks and costs of change and result in superior solutions. The term ‘Design Thinking’ has a textbook definition but for engineers, it essentially places the vast potential of human creativity inside a highly functional, structured methodology. It encourages teams to generate innovative ideas that come to market with low risk, and rapid iterations – so that the end result is feasible, desirable and viable.

Design thinking is a humancentered approach to innovation that draws from the designer’s

toolkit to integrate the needs of people, the possibilities of technology, and the requirements for business success. Tim Brown, Executive Chair of IDEO Design Thinking in practice Having recently presented at the IPWEAQ 2019 Annual Conference on behalf of Aurecon and with Engagement Plus Associate, Marion Lawrie, we have seen firsthand results of how the approach of Design Thinking can help us empathise with the challenges being faced by our engineering professions across Queensland councils. In this session, we explored Design Thinking approaches with participants so that they could realise the value of using empathy to tackle the ‘wicked’ problems we face at work. We took participants on a journey where we used design thinking tools such as ‘stakeholder mapping’ and the ‘facilitation toolkit’ to solve current challenges being faced by engineers. This

included exploring challenges such as managing up, getting chartered and integrating sustainability objectives into their work. By having a human-centric approach, the participants were able to empathise and discuss meaningful steps which could be taken as ‘progressive leaders’ in their workplace which balanced a world of constrains and competing requirements, in a way which is positive, useful and viable. Most importantly, participants in the U35 Design Thinking Workshop were able to walk away with a commitment to being progressive leaders with 3 goals to action in the coming months. What 'Back to the Future' Teaches Us About Innovation Predicting the future isn’t easy, even Back to the Future, the smash-hit movie trilogy, couldn’t do it for 2015. But don’t dwell on the fact that hoverboards and flying cars aren’t the dominant form of transport yet – be excited that the combination of empathy, design and technology enables us to create exponential value

for people’s lives. As we learn to better integrate human-centric design approaches into the way in which we work with technology, we will be able to realise the intangible and commercial value we can bring to the table as design thinkers who are future-ready. So grab yourself some self-lacing trainers from Nike and use Marty McFly as a role model: Seize opportunity where it comes, never give up and always look to the future. We’re engineers, after all. So, for where we’re going, we don’t need roads. We carve our own.

I am delighted to become Vice President of IPWEAQ for the next two years. The role of the Vice President is primarily to preside as Chair of Board meetings in the absence of the Chair (the President). The Vice President, and the President are also ex officio members of all IPWEAQ committees and Working Groups. The Vice President also has roles under various policies, for example, the RPEQ Assessment Board Policy. The IPWEAQ Board is committed to reviewing its representatives on all committees, Councils, Trusts etc – internal and external – at least

every two years. This is to ensure that there is constant renewal and all members are given an opportunity to be involved in any capacity from time to time. A recent review of the RPEQ Assessment Board Policy modified the structure to provide for greater representation. Under Rule 2 of that Policy, the IPWEAQ Vice President is the Chair and under Rule 1, there are now eight Assessment Board members. Those members are Craig Murrell, Tony Jacobs, Andrew Gibbs, Graeme Wills, Andrew Ryan, Moira Zeilinga and Kevin Bickhoff.

Manager has taken on the role of coordinator and I look forward to working with Kate and the members of the newly-formed Board to consider our role as an assessment entity under the legislation.

next generation report We hear a lot about emerging professionals and the future of public works engineering but what do we know about the next generation? 1. The next generation have arrived! Millennials (born between 1981 and 1996) now constitute 35% of our workforce. The next generation, Gen Z or postMillennials (born late 1990s to early 2000) now occupy up to 10% of roles. So almost half our workforce is now ‘the next generation’. And we are delighted so many of our future leaders were inspired to follow their parents into public works engineering and we look forward to seeing their development and contribution to our communities in the years to come. Please send in your photos! 2. Gender distribution may be trending towards 50/50 Statistics from the 2019 IPWEAQ Annual Conference suggests the next generation has a more even gender spread with an equal number of female engineers in those younger age groups. We are keen to track this trend to see if it sustains over the longer term and whether it is indicative of other sectors or unique to us. What will this trend mean for the future of our sector and our communities, our workplace and workplace practices? Will we see a greater take-up of paternal leave to raise families?

Ged and Matthew Brennan #IPWEAQ18 The Great Debate

We are however excited to support all our public works professionals and will continue to do this by regularly seeking your feedback

Engineering for Public Works | December 2019

and input to influence our developing priorities, solutions and services.


We surveyed delegates who attended our inaugural U35 Design Thinking workshop at the Annual Conference, to discover what problems or challenges they encountered in their workplace and how these could be resolved utilizing the CASE framework. The topic was, ‘leadership by design’ which combined multiple challenges on time management, dealing with expectations, balancing sustainability with current industry standards and costs, breaking silos within a company and feeling inadequate. The Learning Hub Emerging Professional pathway covers nine topics of relevance to emerging professionals transitioning from university to the workforce:

3. They care about learning and their personal development

If you manage or supervise Emerging Professionals in your organization, please take time to discuss their development and the challenges they may be facing, and offer the guidance you received (or should have received) in the early stages of your career.

Demonstrating their potential! The Geoff Wilmoth Best Paper award was won this year by Clarissa Campbell, Senior Engineer - Stormwater Infrastructure at Moreton Bay Regional Council. Our 2019 Young Engineer of the year is Michael Shellshear, Manager Projects, Proterra Group who is also a regular contributor to articles in our journal. We welcomed The Pretengineers to our community at the Annual Conference (see their video in the Knowledge Centre conference collection). Ryan Loomans and Jack Aubort shared their initiative launching Australia’s first podcast dedicated to supporting young engineers transition from university to the workplace. And we are very proud of our four IPWEAQ Ambassadors (Jessica Kahl, Josh Flanders, Ben Ash and Maddy Stahlhut) who proactively engage with us to help guide strategy. With emerging professionals such as these, the future certainly looks bright!

PEOPLE AND CAPABILITY REPORT Nadia Marks Director, People & Capability The IPWEAQ Learning Hub has finally arrived! This exciting new project has been under development for several months and we were delighted to launch the Hub at the Annual Conference in Brisbane in October. The Learning Hub addresses a need in our sector to develop non-technical skills. In the March 2019 issue of Engineering for Public Works, I emphasised the importance of developing both technical and non-technical skills. Most people understand the importance of having a grasp of soft skills including influencing, selfawareness and self-moderation, designing strategic conversations, developing emotional intelligence, showing trust and authenticity as leaders, communication skills, business acumen, working efficiently, self-promotion etc. The challenge was not why nontechnical skill development is important but rather, how to deploy training and opportunities for professionals to develop these skills. To address skill shortages, the preferred option for employers is often to upskill existing staff however the following challenges are often raised: • Finding quality trainers to deliver locally

• The costs of travel to send staff away to attend training is too high • Lack of time for staff to attend training • Course costs are often too high • Finding courses with relevant content offered by reputable organisations So there is a critical and desired need for non-technical training however there are obstacles to fulfilling this need. And that is the challenge we have addressed with The IPWEAQ Learning Hub. The Learning Hub is an online training portal designed and created specifically for the public works engineering sector. This is the start of an exciting new journey to connect public works engineering professionals in their

Engineering for Public Works | December 2019

continuous learning journey. We have created a number of courses in The Learning Hub called ‘learning pathways’ in modular format delivered over 10 weeks with each step focussed on one specific non-technical topic to avoid information saturation. The learning pathways have been designed to suit engineering professionals at various levels of their career from Emerging Professional, to mid-career and senior leadership. In addition to the career pathways, we have also developed two pathways which focus on personal growth, development and mastery. These are for women in engineering and men in engineering. Each module within a pathway has been carefully chosen and curated

adac REPORT Mark Lamont Director, Information & Resources The Strategic Reference Group (SRG) which shapes and directs the ADAC framework has met twice in this second part of the year with lots of progress on the restructuring of the Technical Reference Group (TRG). We have now established seven Communities of Practice (COPS) focussed on their respective asset types: 1. Water and Sewerage 2. Transportation 3. Open Space 4. Stormwater 5. Cadastre 6. Buildings 7. Electrical/Communications These smaller focussed Communities are better positioned to respond to the needs of our 21-member ADAC Consortium. Each COP will comprise experts in the particular asset type

with membership derived from Consortium member councils and utilities. The COPs will develop the detailed asset descriptions and will commence work early in the New Year. The TRG will develop the Terms of Reference for the COPs and will meet regularly to consider the recommendations from the COPs In other ADAC news, IPWEAQ is pleased to welcome Shellharbour City Council and Ipswich City Council to the ADAC Consortium. In-house induction days have been delivered with both new members attending the recent TRG meeting with commitments to participate in the newly created COPs.

Engineering for Public Works | December 2019

Shellharbour is the third NSW council after, together with Port Macquarie-Hastings and Tweed Heads to join the Consortium. The growing interest from NSW councils offers an opportunity to further advance ADAC as it expands its integration with GIS and other databases saving time and costs for asset owners and developers. If you would like to learn more about the benefits of ADAC and membership of the Consortium, please don’t hesitate to contact Mark.Lamont@ipweaq.com on (07) 3632 6806. An ADAC information day can be arranged at your preferred location.


knowledge centre report Mark Lamont Director, Information & Resources The weeks following IPWEAQ’s Annual Conference are always a busy time in the Knowledge Centre. Our conferences continue to go from strength to strength and the Proceedings from this year’s conference represents the largest collection of material to date. The Conference Proceedings include the audio visual of the presentation, the accompanying PowerPoint and a paper. While you are only able to attend in person a single session in a Stream, the Conference Proceedings offers an opportunity to view the presentations in all other streams. The Conference Proceedings are accessible to all paid delegates however if you were unable to attend the conference, you may purchase the Proceedings for $600 (member) or $900 (non-member) offering great value for a total 22 CPD hours at $27 per hour. Each year after the Annual Conference, we see a spike in Knowledge Centre activity as new users discover the extent of our globally recognised Knowledge Centre including content delivered at previous Annual Conferences and branch conferences. If you are an IPWEAQ member, you can access the Conference

Proceedings for all previous branch conferences. It is an exceptional resource and we hope you make the most of it. From Darren Shepherd, Shepherd Asset Management Solutions: “By the way the Knowledge Centre with material from past conference presentations is amazing. Such a great site. Well done.” One of the essential development principles of the Knowledge Centre since inception has been the needs of the User and how they want to access information. As a result, we recently created a new Community in the Knowledge Centre for our Public Works Technical Subscription (PWTS). The PWTS subscription packages includes Standard Drawings, QUDM, Lower Order Roads Design Guide and the Supervisor’s Handbook. These technical solutions continue to be available in separate collections for those who have subscribed to individual publications including QUDM. A NSW Coronial Inquiry arising from the death of a young boy in a stormwater inlet following heavy rains, led to a recommendation by the Coroner that the Public Works Advisory (NSW) develop guidelines for the safe design of stormwater inlets in NSW. In response, we were approached by the NSW Department of Planning, Industry and Environment, Public Works Advisory Division which sought to adopt QUDM as it

meets the criteria specified by the Coroner for suitable guidelines. In response, and given that this arises from a tragic situation, QUDM was offered to the NSW Department at a heavily discounted rate for access immediately to all NSW councils. Several NSW councils have subscribed to QUDM directly. The review of QUDM in 2020 will take into consideration that it is now widely used in other jurisdictions. Finally, the IPWEAQ Knowledge Centre has again been included in the International Register of Libraries by the Library Publishing Coalition in the United States. This Register recognises the high standard of content published in a collection for specific users for a particular sector. The Register recognises that many learned articles are published firstly in the IPWEAQ Knowledge Centre eg papers submitted by presenters at our conferences and our role is to ensure the dissemination of articles of value to our sector by way of access to the Knowledge Centre. Please do not hesitate to contact Mark.Lamont@ipweaq.com or 07 3632 6806 if you have any requests or issues accessing the IPWEAQ Knowledge Centre.

street design manual Craig Moss Director, Professional Services IPWEAQ is pleased to introduce the Street Design Manual: Walkable Neighbourhoods which was launched at the 2019 Annual Conference by The Honourable Cameron Dick, Minister for State Development, Manufacturing, Infrastructure and Planning. John Derbyshire also presented to delegates at #IPWEAQ19 on the history of the development of the new Manual, initiated in 2016 with surveys of our members. John emphasised that the Street Design Manual is a practical and relevant guide as it was developed by industry for industry. The two project Working Groups (Planning and Detailed Design & Standards Working Group) have worked tirelessly to produce a draft of the Manual for industry consultation with detailed principles, objectives, strategies and guidance to be provided in the final document (following consultation). The Street Design Manual has three parts: Part 1 – Planning and Design Guidelines Guidelines on the planning and urban design of neighbourhoods, incorporating community design, the movement networks, the open

space network, lot design and centres. Part 2 – Detailed Design Guidelines Guidelines on the detailed design of neighbourhood infrastructure including traffic, streets, active transport and services. Part 3 – Practice Notes Practice Notes offer additional information on Parts 1 and 2 with examples, supporting information and references. All parts draw from and include material from other documents including the Economic Development Queensland (EDQ) guidelines and the Queensland Housing Code and Reconfiguration of a Lot Code.

with reference to Part 3: Practice Notes The videos of the various presentations are available in the IPWEAQ Knowledge Centre. Workshop delegates were encouraged to provide input into the content of the Street Design Manual including solutions to the areas requiring additional information plus case studies to include as Practice Notes. To be involved in ongoing discussions regarding content, you can join the Consultation Portal. To access this portal, please contact Craig.Moss@ipweaq.com.


The draft Street Design Manual can be accessed via the IPWEAQ website Following the official launch, Thursday 24 October, we hosted an industry briefing and workshop. This event attracted 50 delegates with presentations from those pivotal to the development of the Manual including: • Background on the development of the Manual • The State Planning Policy and Model Code • Part 1: Planning and design guidelines with reference to Part 3: Practice Notes • Part 2: Detailed design guideline

Engineering for Public Works | December 2019


qldwater ceo’s report Dave Cameron CEO, qldwater With our major events program for 2019 now complete, our attention has turned to some key contracted activities, further developing the industry roadmap and planning for 2020. The highlights reel: Environmental stewardship Sewage and Water Environment Advisory Panel met in October and hot topics for the group include the development of a consortium approach to progress work on emerging contaminants, which may include research collaboration, new recycling guidelines, point source offsets, Great Barrier Reef regulation and projects including the Reef Councils Major Integrated Project (stage 1). A further workshop was held with councils on this last activity in early November, aimed at assisting participating councils in developing project/ trial application for the next Life Cycle Analysis stage for treatment technologies and potential offsets. The LGAQ program is funded by the Department of Environment and Science and managed by qldwater, with the intention being that the work will provide a fitfor-purpose investment strategy for best managing the way STPs reduce contaminants reaching the Reef.

3rd Party Equipment on Water Utility Infrastructure In simple terms, we are seeking to improve the way telecommunication carrier equipment is managed on infrastructure like water towers, with particular focus on safety – public health (contamination through rooves etc) and worker safety (electromagnetic radiation and access). The ultimate goal would see changes to the federal Criminal Code and Telecommunications Act, which currently stop water utilities “interfering” with equipment (powering down to undertake essential maintenance) and make it very difficult to object to a carrier wanting to access a

Engineering for Public Works | December 2019

site. In November, I briefed the federal Standing Committee on Communications and the Arts as part of its Inquiry into the deployment, adoption and application of 5G in Australia. SWIM 100% of members used the State-wide Water Information Management system to report this year, a fantastic result for Dave Scheltinga who puts an enormous effort into coaching staff in their compliance reporting. We have signed up a few new swimlocal subscribers as well, with hopefully some interest growing in NSW. This time of year is also for planning enhancements to the product.


Skills Plenty on the agenda again with the next significant activity being the March Water Skills Forum, but in the meantime we are focussing on gathering data to develop a state-wide operator workforce plan. One of the most exciting developments is the growth in the regional Water Industry Worker Program, now looking increasingly likely to expand beyond the current active councils in Mackay, Whitsunday, Cairns, Townsville and Burdekin. 2020 Events Just two to highlight at this point – Redland City Council has kindly agreed to host our Annual Forum in September, but the other particularly exciting new one we are trialling is a “small communities solutions” event in Goondiwindi on 13-14 May. Split into thirds, the event will include a short tour, a chance for some innovative water and wastewater treatment solutions to be showcased, and a strategic planning session tackling some key sustainability questions for small communities. Most Queensland service providers, even the big ones, have small communities to manage, so the topic is a great bridging activity. Details are still being finalised but it will also be supported by the NSW Water Directorate.

QWRAP The Queensland Water Regional Alliance Program has held Chairs and Coordinator - and Steering Committee meetings and most regions have commenced new collaborative projects. Given upcoming elections in 2020, we have commenced planning for advocacy to expand the program with LGAQ.

Other Events It was pleasing to see a successful IPWEAQ annual conference and I enjoyed catching up with people during the Luggage Point and Eagle Farm Pump Station technical tour and at the water presentations. Thanks again to Trevor Dean for stepping in at short notice to deliver a great presentation on qldwater strategy. We have contributed to several other industry events including WIOA interest days in Cairns and Ipswich, and QWater in Brisbane. The latter included sponsoring AWA to assist with live-streaming a panel session for members entitled Can we prevent Australia’s Havelock North - Learning lessons from other’s experiences. Our last TRG meeting for the year is on 6 December. I’d like to acknowledge with pride the enormous efforts of the qldwater staff over 2019 and wish our members the best for a safe festive season. If you are lucky enough to be at the Gabba in the next couple of months it’s fairly safe to assume I will be too, so drop me a line if you want to say gidday.

Water from Mackay Regional Council’s Marian Water Treatment Plant was selected top drop in the fifth annual Ixom Best Tasting Tap Water in Australia Competition held at the 3 Peaks festival in Dunkeld, Victoria in October, where festival goers participated in a blind taste test of seven entries from across the country.

Mackay is on a winning streak, having won the qldwater on tap Best of the Best Queensland Water Taste Test at qldwater Annual Forum for the last two years in a row. Stuart Boyd from Mackay Regional Council was pleased to accept the trophy on behalf of the Mackay water team.

Engineering for Public Works | December 2019

“In many ways having the community do this was a true test of the best tasting water rather than being conducted by a panel of industry professionals that might focus on other aspects of the water other than taste,” Stuart said. “All state finalists had excellent entries and there was plenty of


debate in the community about what they thought was the best tasting and why. The overall consensus was that they were all fine drops and there was increased awareness of not just the health and economic benefits of tap water but also the high quality of water that is available around Australia.” Stuart said the win was a pleasant surprise, providing great recognition to the dedicated and professional Mackay Water Treatment Team. The source of water is the headwaters of the Pioneer River which originates in the tropical rainforests of the Eungella National Park and the Crediton State Forest. It is treated at the Marian Water Treatment Plant which provides water to more than 6,000 Marian and Mirani residents. The plant

uses clarification, filtration and chlorine disinfection processes to treat the water to meet the Australian Drinking Water Quality guidelines. The other samples came from Nowra in New South Wales, Launceston in Tasmania, Swan Reach in South Australia, Geelong in Victoria and Perth representing Western Australia. Mackay will now go on to represent Australia at the Berkeley Springs International Tap Water Tasting competition in the US next year, and will get to host the next national event on home turf.

New Regulations Will Affect All Communities in Great Barrier Reef Catchments


Communities in Great Barrier Reef catchments may find the advantages of living near a World Heritage Area to come with a down side as higher scrutiny leads to increased regulation. Primary producers, point source industries and councils (including sewerage service providers) will bear the brunt of new Reef Protection Regulations that take affect from 1 December 2019. The draft legislation was introduced to Parliament in late April and passed on 19 September following extensive consultation between 2016 and 2019. The Regulations introduce a raft of requirements for some primary producers including record keeping, minimum practice agricultural standards, nitrogen and phosphorous budgets for sugarcane farmers and Environmental Authorities for new cropping and horticulture activities. They set minimum practice standards for all sugarcane, beef cattle grazing, grains, banana and horticulture production in Reef regions along the coast of Queensland, excluding Cape York. This focus reflects the recommendations of the Reef Taskforce and ongoing science and research that highlight the

importance of addressing diffuse run-off to reduce stress on the Great Barrier Reef. The Regulations also include specific requirements for "new, expanded or intensified industrial development" that applies to ‘point source’ discharges including sewage treatment, aquaculture or intensive animal industries. A key element is that any new, expanded or intensified ‘Environmentally Relevant Activities’ must not increase nutrient or sediment pollutant loads flowing out of each reef catchment. For sewerage managers, this approach of “nonet-decline” means that activities must be managed so that they do not contribute nutrients in addition

Engineering for Public Works | December 2019

to those currently allowed in their Environmental Authorities (EAs). If this cannot be achieved through changes to design, operation or reuse – which will often be the case for large communities with advanced STPs - the only option is to rely on the new Point Source Water Quality Offsets Policy which was finally released in October. Offsets aim to allow for discharges that cannot otherwise be managed by reducing nitrogen or sediment loads elsewhere so that the total loads reaching the Reef are reduced. The Regulations have introduced significant new uncertainty for GBR communities. The focus on agriculture has been interpreted by some stakeholders as unfair for a sector that is already struggling


in some areas. Some stakeholders including many primary producers have quickly adopted enhanced practices as a way to demonstrate their commitment to their industry and protecting the land they manage. Others have sought to discredit the well-established science underpinning the Regulations. Existing EA holders including some council sewerage services have interpreted additional requirements as inequitable because their sites are already heavily regulated and many have been upgraded over the past two decades. There is concern that “no-net-decline” means any growth of Reef communities must be addressed through expensive treatment alternatives or rely on a new and largely untested Offsets Policy. Despite these challenges, the new Regulations could prove a benefit to urban communities as well as the Reef. The Regulations were initiated to avoid the GBR being ranked by the World Heritage Committee as ‘in-danger’ in their next review in 2020, but this has also brought some much-needed attention and increased investment. While most funding will be directed to the agriculture sector, there is some hope for urban areas as well. The State has recognised the need to invest wisely in public sewerage systems and has partnered with LGAQ and qldwater in the Reef Councils Major Integrated Project to assess options to best fund improvements to council sewerage systems. The Department’s “report card project” represents a genuine attempt to engage councils and industry experts to develop a meaningful assessment of the management of STPs and their networks. The long-delayed new Offsets Policy demonstrates a willingness by the State Government to develop essential innovative alternatives to direct attention to catchments and diffuse contaminant sources and build an approach that can include councils and primary producers. A recent joint press release by the State and Federal environment Ministers reflects the (welcome) collaboration by those two levels of Government on issues facing the reef. The Ministers jointly supported

the large body of peer-reviewed science that supports the need for change in the catchments, acknowledged climate change as the key driver of degradation while also recognising the role of Traditional Owners in protecting and managing the Reef. In an unusual show of joint support, the forum “endorsed current reef management strategies and highlighted the importance of a coordinated Federal and State approach in protecting the Reef’s future”. This collaborative approach is key to releasing appropriate funding to allow Reef communities to work collaboratively to ensure the sustainability of the World Heritage Area they manage for the benefit of all stakeholders.
