elcome to the last edition of Trenchless Australasia for 2022.

What an achievement it is for many to make it through these last 12 months. From completing major projects to surviving another year of COVID-19, and rebuilding following the effects of the recent floods, 2022 has been another challenging year for the industry.

However, the trenchless sector has come out stronger and more versatile, by enhancing its technology and networking back in person to create better solutions for the challenges faced.

This year was also one of firsts ‒ both personally and the magazine itself. My first edition as editor, attending my first No-Dig Down Under convention, and the magazine shifting from four to six editions a year for the first time.

In the spirit of firsts, Trenchless Australasia has introduced a new regular column tracking new appointments in Australia and New Zealand’s trenchless industries.

‘People on the Move’ will be published in every print edition of the magazine, celebrating the people who make the industry what it is. The column gives companies the opportunity to introduce new team members to the Trenchless Australasia’s audience and position them as a point of contact for their business.

In this edition we celebrate and welcome kwik-ZIP’s Phil Micallef, PSSS’ Michael

Hodnett, and Veolia’s Jason Climo. To read more about their roles and ambitions, check out the People on the Move feature on page 66.

This edition also highlights the safety and training work being done in the industry. While trenchless technology and methodologies are still considered a niche segment of the construction industry, significant work is being done by stakeholders to ensure the benefits of no-dig methods are becoming mainstream, and importantly completed in a safe and sustainable way.

In addition to this theme, other unique features in this edition include Horizontal Directional Drilling, Rehabilitation and Repair, Microtunnelling, Software and Technology, and Relining.

Jim Pound also shares his thoughts on the industry for the Trenchless Pioneers feature, stating that if the industry continues to grow at the same rate it has in the past 20 years, that he is excited to imagine what may be possible.

The team from Trenchless Australasia thank you for your support during 2022, and wish everyone a happy and safe Christmas and New Year. We look forward to joining you again in 2023.

Happy Reading!

NEWS FEATURE IN BRIEF

ASTT hosts trenchless stream at Water NZ Water New Zealand’s 2022 Conference and Expo brought together operators from the industry in to share insights and practical knowledge with one another.

The Australasian Society for Trenchless Technologies (ASTT) provided a discerning stream of talks in collaboration with Water New Zealand in October – bringing operators from the industry in to share insights and practical knowledge on utilising trenchless technologies in sustainable industry projects.

Water New Zealand’s 2022 Conference and Expo brought together some of the most insightful speakers in the water industry last week to share their ideas and vision for the future of sustainability in the industry.

The Australasian Society for Trenchless technologies (ASTT) delivered a stream in collaboration with Water NZ. The series focused on the innovations present in existing projects, from the massive northern interceptor pipeline to the relocation of curved alignment tunnel in Mt Eden.

Operators in the water and wastewater industry were given the opportunity to connect and collaborate, helping to form Whanaungatanga – or, ‘close connections or kinship’ – within the industry to allow innovations to thrive.

Local Government Minister Nanaia Mahuta’s keynote address called on all operators within the industry, saying that the time to make a change is now.

“The current changes and reform present us with the opportunity to be aspirational about how we want key services to be delivered in the future,” Mahuta says.

Watercare kicking off $20 m wastewater upgrade Watercare is set to begin laying down the foundations for a new $20 million wastewater pipe network to reduce wastewater overflows and cater for growth in Rosedale and its surrounding suburbs.

Alongside the $21.5 million Mairangi Bay Pump Station, the new wastewater pipeline will increase the wastewater transmission capacity and reduce wet-weather overflows in the East Coast Bays area.

The construction of the 1.75 km pipeline is one of the many key infrastructure projects that Watercare currently have in the works in the Rosedale and Mairangi Bay areas.

Although it plans to carry out much of the work in Windsor Park and Centurion Reserves, Watercare acknowledged that people may experience disruptions along Apollo Drive and Centurion Drive such as reduced on-street parking, lane widths, speed limits and pedestrian detours.

Watercare is to lay down the foundations for a new $20 million wastewater pipe network.

Rob Carr takes home CCF National Award

Rob Carr wins at national CCF Awards.

14 TRENCHLESS AUSTRALASIA DECEMBER 2022

Rob Carr has taken home the 2022 national award for civil construction at the National CCF awards in Canberra.

The microtunnelling specialist won the award in the $5 to $10 million category for its Gnangara Branch Sewer section 2 project, located in Western Australia.

The project, undertaken on behalf of client Water Corporation, involved installing a new pressure main to an existing sewer section.

The company’s expertise in microtunnelling saw overcame a number of challenges for the project, including in-ground infrastructure and a limited time frame.

Teams completed four drives reaching a total 500 metres of microtunnelling, and managed to construct a DN1000 glass reinforced plastic, 259-metre microtunnel in 10 days.

The Gnangara project was automatically nominated following Rob Carr’s win at the CCF WA Awards in September.

Managing director Damien Maitre received the award on behalf of the company.

End of the line for CRL TBM The end has come for City Rail Loop’s tunnel boring machine.

Tunnelling works for Auckland’s CRL have been completed with the final breakthrough of the tunnel boring machine (TBM) at Te Waihorotiu Station (Aotea) on 14 September.

Over the duration of the project, the TBM bored a total of 3.2 km of tunnels, placed over 2000 segment rings and removed more than 260,000 tonnes of spoil.

The TBM is an earth pressure balance machine, meaning it can stabilise the earth it excavates to reduce impact on the surface.

It has a 7.15 m diameter, weighs 910 tonnes and is 7.15 meters in length.

Now that the tunnels are completed, crews will begin work fitting them out with everything they will need for use: • 16 km of rails • 816 km of signal cables • 247 km of low voltage cables • 74 km of cable containment • 86 km of traction cables.

The Dame Whina Cooper is now in the process of being lifted out. Despite being custom built for the CRL project, pieces of the equipment will be returned to Germany where manufacturers Herrenknecht AG will repurpose them for future machines.

The 75 tonne cutter head was removed last week, while the shield is being dismantled into six pieces that will each be crane-lifted above ground for removal.

DJ Mac Cormick completes 234 m microtunnelling installation DJ Mac Cormick Contractors have achieved yet another shining success on one of its longest single drives for non-man entry to date.

DJ Mac Cormick Contractors has undertaken one of the longest single drives for an 800 mm diameter closed face slurry shield micro tunnelling project, with no-man entry available for installing intermediate jacking stations or slurry pumps.

The project was completed on behalf of the city of Swan, located in the eastern metropolitan region of Perth in Western Australia.

The drive length for a main drain was 234 m and due to the high level of traffic, community use and business trading work was only able to be undertaken over the Monday to Friday traditional work week.

Launch and receival shafts were constructed utilising Ground Support Systems (Aust) shoring and associated safety equipment, which included certified structural KPA ratings for all the shoring.

Temp designs were certified by structural engineer & undertaken for thrust block, entrance wall and concrete pad.

DJ Mac Cormick Contractors had previously undertaken the previous stage back in 2019.

The works in this stage involved several high complexity traffic MGE plans staged to ensure continual flow traffic through locality in order to minimise disruption to businesses as well as the broader community and residents.

Ground conditions ranged from stiff clay to running sand. Underground streams encountered throughout the project also meant working on river sands and river stone cobbles during the drive length. All works were undertaken within 20 mm tolerance over drive.

Upon completion of the drive, various tie in works and open cut drainage excavations including the construction of drainage manholes and side entry pits were required. This included the construction and maintenance of connections to existing drainage structures.

CCTV inspection of all lines was also required for this stage of the project, with a quality insurance pack and drawings provided upon completion.

TRENCHLESS PIONEERS

Full name: Jim Pound Company: S&Z Australia Role: General Manager

Trenchless Pioneers In a bid to celebrate the achievements and growth of the trenchless industry and the ASTT, Trenchless Australasia will be running a new question and answer segment. In this edition, the Trenchless Pioneer is Jim Pound, the General Manager of S&Z Australia. This is his story.

I

n your own words, how would you explain what the trenchless industry is?

The trenchless industry provides methods that allow infrastructure to be delivered safely with minimum impact on the environment and the community.

How did you become involved in the trenchless industry?

My initial exposure to trenchless was in the early 1990s when working as a plumber.

I engaged the services of a pipe bursting company to replace a very deep sewer in Ardeer. Since then, I have worked with several companies including suppliers and trenchless specialist companies. These companies exposed me to various trenchless technologies such as slip lining, pipe cracking, pipe bursting, fold and form pipe lining, HDD and microtunelling.

What is a standout trenchless project or milestone you have been involved in?

Our involvement in a large project in the NSW Mountains which required us to deliver over 6 km of communication and power through extremely hard rock in a remote and challenging environment is a project that we are extremely proud of. Working day and night in snow and rain to deliver the project

18 TRENCHLESS AUSTRALASIA DECEMBER 2022

within the necessary time frame, requires great dedication from our staff and we are extremely grateful for their commitment.

What is the best part of trenchless technology? And how has it evolved since you first became part of the industry?

Trenchless technology is always evolving.

New techniques and improvements to current methods see the industry continually growing and improving. Most companies within trenchless technology are prepared to share experiences to help improve the industry and there is good collaboration within the various companies even if they may compete at times.

Which form of trenchless technology do you think has had the most transformation and why?

Tunnel boring continues to evolve and appears to be becoming a preferred method of trenchless technology due to the advancements in techniques which see longer lengths and larger sizes achievable.

Where do you see the trenchless industry in the next 10-20 years?

If the industry continues to grow at the same rate it has in the past 20 years, I am excited to imagine what may be possible. I

expect the opportunity to reduce emissions and minimise impact on the environment and provide safer work practices will see projects that would normally be delivered by traditional open trench methods be replaced by trenchless technologies.

With trenchless technology having a strong ability to reduce the impact on the environment, what more do you believe the industry needs to do in order to further reduce emissions and the impact on the environment?

The industry should lobby water authorities and other utilities to educate them of the benefits trenchless technologies provide to the environment. The equipment manufactures should continue to invest in technology to investigate alternate power sources for plant and equipment.

How has the industry progressed in being more diverse?

When I commenced in the industry there were no women in the trenchless space. Over the years we have witnessed more women become involved and prove to be extremely valuable contributors to the industry. S&Z Australia welcomes and encourages women to apply for any position we have available.

S

ewer Network in Dandenong Ranges Yarra Valley Water is installing 91 kms of a reticulated pressure sewer network in the Dandenong Ranges. The geological make-up of the ranges, as well as a number of hard-to-access areas, has necessitated the use of trenchless technologies For many years, development of the Dandenong Ranges has been held back by lack of access to a sewerage network. Homes in the area rely on septic systems that require property owners to manage their own wastewater. Some of these older systems discharge grey water directly into storm water drains, impacting delicate ecosystems and waterways. The new sewerage network will allow the local community to modernise while still preserving the delicate environment.

The project faces several challenges. Delivery partners Interflow, Melbourne Pipelines and

20 TRENCHLESS AUSTRALASIA DECEMBER 2022

Pressure Sewer Services Australia (PSSA) are installing DN 50 to DN 90 polyethylene pipe around existing services, dense and protected vegetation, narrow roads, steep hills, and a community going about their daily lives.

Shem Macdonald, construction manager for Melbourne Pipelines, talks about some of the challenges their drillers have encountered.

“We’ve gone from friable red soils in Monbulk to hard ground, boulders and cobbles higher up in the hills. The drillers’ experience and expertise are needed to determine how we deal with each ground type: do we knock floaters out the way, grind through them or cut our losses and stop to excavate and remove them?” said MacDonald.

“We’re also relying on proving pot-holes and excavations to provide a better idea of ground conditions so we can make more informed decisions on our own drill rig

selection, positioning and set-up, and using B&M Infrastructure’s pneumatic drill rig for exceptionally hard ground.”

The narrow lanes, dense vegetation and limited space mean contractors are using small water trucks, vac trucks and excavators to reduce their footprint. Site dumpers transport materials, equipment and longer hoses to the drill truck, offering more flexibility with drill truck set-up.

“We have a variety of trenchless options for property connections such as horizontal directional drilling, a piercing tool, hydro borer and bed borer,” says MacDonald.

Horizontal directional drilling (HDD) has been chosen to complete the project, as the area is home to some important native species including the Giant Gippsland Earthworm, Warragul Burrowing Crayfish and Strzelecki Gums.

Running the pipeline along already disturbed areas such as the roadside, combined with the use of HDD, will enable operators to keep the impact on these species to a minimum, as well as reduce the cultural heritage and potential artefacts of the area’s Traditional Owners.

The pipeline will assist development in the south-west growth corridor of Warragul, while serving double duty by increasing the volume and security of water supplies for the town of Drouin.

Works on the pipeline are expected to be completed in late 2023, with further work possible in the future to extend it to the south basin, in line with potential urban development.

The towns include two of the most rapidly growing populations in the Gippsland region, prompting the company to keep ahead of this growth by constructing a new 4.3 km water main.

SRL CEO Frankie Carroll was encouraged by the interest in the project.

“This competitive process has been a massive vote of confidence in Suburban Rail Loop – with construction giants from around the world vying to partner with us to deliver this city-shaping project,” said Carroll.

The project is well on track with the first contract to be awarded next year for twin tunnels between Cheltenham and Glen Waverley.

Initial works on SRL have already begun in Clayton and major works have been given the green light due to an extensive Environmental Effects Statement.

Jacinta Allan, the Minister for Suburban Rail Loop spoke indicated the project could generate up to 8000 local jobs, creating opportunities for professional growth.

“SRL East is a project Victoria needs… this is an exciting day as we move closer to the start of tunnelling,” said Allan.

Veolia: The vanguard for safety Veolia claims few companies have had as much of an influence on safety standards for high pressure water jetting than it has.

I

n 2021, Veolia began developing a series of guidelines and safety measures collectively called its high-risk management standards (HRMS).

The impact of the HRMS is being seen in Veolia’s operations around the world.

In Queensland, the company performs maintenance and operation work on water and sewage assets, looking after all elements of the transport network – the pipes – that keep water and wastewater going where it needs to.

Safety is success Daniel Faccio is a senior asset engineer for Veolia’s Queensland branch. His work involves customer service and keeps him close to Veolia’s teams on the job. Having been with Veolia for almost a decade, Faccio has seen how the company’s approach to safety has taken shape in its workforce, but also on the industry as a whole.

Faccio says that decades of evidence from work in the field shows that the safest work environments are also the most productive.

“Safety is at the forefront of everything we do,” says Faccio. “If the guidelines are

22 TRENCHLESS AUSTRALASIA DECEMBER 2022

well-structured, then the work is safe, and you then get the highest benefit of productivity out of that outcome. That drives us, because keeping our people safe also guarantees the best outcome for our clients,” he says.

High risk does not mean unsafe While there are challenges involved with high pressure water jetting (HPWJ), it is still utilised by Veolia as one of the safest methods for cleaning underground assets like sewer pipes and storm water lines. It is an effective way to remove tree roots, sediment, and other blockages from these assets.

Before the advent of water jetting, crews would have to manually pull through chains or steel cables with discs that would remove blockages. These traditional methods had a long list of heightened risks to work crews, especially when combined with the sheer level of manual handling required to complete them.

“Water jetting makes the cleaning of sewers less labour intensive, it is actually safer for the crews to waterjet then manually pull the traditional discs with tensile cables

or plumbing rods. Combining jetting with a vacuum system just adds another level of safety,” says Faccio.

He explains that most of the risk with water jetting comes from the nozzle. Without the appropriate safety measures, there is a risk that the pressure from the hose will whip the nozzle out of the maintenance hole, which can cause property damage, injury, and even death.

This is where Veolia’s HRMS comes in to mitigate those risks. The company fastidiously assessed all the potential causes of harm across the industry to develop these standards and holds to them without compromise.

“The HRMS is basically Veolia’s Bible,” says Faccio. “Our people know we don’t compromise on safety.”

Specific solutions to safety needs Veolia’s entire fleet of trucks – equipment ranging in value from $200,000 to $1.5 million – are equipped with the highest level of safety equipment. The safety measures cover everything from engineered controls on the equipment, like pressure safety valves, to the

SAFETY & TRAINING

highest quality personal protective equipment (PPE).

The company has introduced a mechanism called a hold to activate on the HPWJ controllers on every one of its trucks. If it is released while the equipment is being operated, the entire water pump systems shuts down – minimising the risk of a loose nozzle causing damage.

“We actually managed to get the industry to incorporate the hold to activate feature into all the new trucks, and we’ve retrofitted it into our entire older fleet as well,” says Faccio.

To get things changed, Veolia has had to challenge the status quo. One such instance was in the standard use of whip checks – a piece of equipment designed to restrain a hose, but not to its full extent. With a whip check in place, hoses can still buck up to a metre at incredibly high speeds.

“Once again, we’ve gone through and retrofitted all of our trucks with a hose stocking – which actually restrains the hose and stops it from whipping out in the event of a connection failure,” says Faccio.

He says that the industry assumption was that whip checks would be suitable, but Veolia upgrading its fleet with hose stockings has raised the bar across the industry.

“You can’t downplay the significance of that step. It’s a huge safety advantage to the industry,” Faccio says.

The right equipment is incredibly important, but even the best pieces run the risk of failure. For this reason, Veolia also Safety observer when performing manual operations as per AS4233.1 Section 1.6.3

RTO training for class B As per AS4233.1 Section 7

Hold to activate as per AS4233.1

rigorously pressure tests all its hoses as part of its standard procedure. If a hose does break, it gets repaired and tested again to make sure it is fit for use with the minimum possible risk of rupturing.

All hands on deck Veolia’s relationship with the industry has demonstrated a far-reaching interest in improving safety measure.

The company worked with an Australian supplier to make anti-withdrawal devices – a kind of customised maintenance hole lid – available to the whole industry. Once again, the company is in the process of outfitting its

fleet with these devices.

“The device prevents the nozzle from coming back out towards the operator. It’s been a safety-first move for us, and now that technology is being shared with the industry, available for all people to use as part of their safety features,” says Faccio.

Specific designs were needed to ensure the safety of crews undertaking HPWJ work on asbestos sewer pipes which in fact may have been in breach of safety laws. On behalf of the industry, Veolia engaged in discussions with the safety regulator to determine the level of risk associated with this work.

Around 30 to 40 per cent of sewer pipes in Queensland are made of asbestos. According to Faccio, this could be as high as 80 per cent, depending on when the council in question laid the original sewer infrastructure.

Originally, the commonly held industry opinion was that asbestos was safe if it was wet, as in HPWJ work. In teaming with regulators to test the air quality at work sites, Veolia found below-detectable levels of asbestos in the air.

To address this, Veolia modified its safe work method statements (SWMS, or “swims”) to control for the unique risks posed by asbestos pipes, as well as introducing an asbestos management plan for all work.

For the benefit of all industry operators Veolia didn’t have to raise the bar in the way it did. Safety is now well-known as a strong driver of value. The capital expenditure is offset by increased productivity in the field and less downtime from equipment failures or injury to personnel, increasing value for customers.

More importantly, Faccio says that keeping workers safe is always the right thing to do.

“We weren’t willing to go along with the industry norm when it came to delivery in the field, so we took it upon ourselves to put further practical safety controls in place to make sure the risks were removed.”

Veolia continues to work towards a safer industry, often driving change at significant cost. There is no doubt that the cost is worth it, both for the company and for the industry as it grows to meet safety requirements, and solutions. Developments for which Veolia is at the vanguard.

“Ultimately, we want everyone to get home in the same condition they arrived to work in,” says Faccio.

HDD

Mitigating climate change risk with insurance Horizontal directional drilling (HDD) is seen as one of the higher risk areas in the infrastructure sector.

Climate change is further increasing this risk as extreme weather events become more frequent.

As Chief Executive Officer for a leading HDD design and construction provider, Maxibor’s Rodney O’Meley highlights the key factors in understanding contract works and equipment insurance policies to ensure adequate cover is in place in this changing risk environment.

W

hy have insurance?

“Simply put, a business can go broke if it doesn’t. One major unforeseen event can stop a business in its tracks, leaving owners and staff without livelihoods, clients without a delivered project and other stakeholders unpaid,” says Maxibor CEO Rodney O’Meley.

It is just not about having insurance.

Operators must know what their insurance policy covers and for how much. A simple certificate of currency explains very little – it is the extent of cover contained in the insurance schedule and policy wording that tells the real story.

O’Meley says it is those HDD providers, with appropriate insurance covers in place, that asset owners and principal contractors should be seeking out to undertake HDD works if they are genuinely serious about mitigating their risk.

Insurable HDD risks In the HDD world, the main risks are covered under contract works, equipment, public liability, professional indemnity and workers compensation insurance policies.

Understanding which HDD risks are covered by these policies and the extent and nature of necessary cover requires alignment of knowledge between HDD engineering, operational, commercial and financial people from the business, as well as the insurance broker and the underwriter.

“If you do not understand what you are insuring and for how much you are just gambling that you will be covered,” O’Meley says.

He says insurance policies are lengthy documents, rarely visited except in the event of a claim. They are accompanied by a policy schedule which often refers to a policy section rather than providing specific detail of what the cover represents.

It can take years of experience to understand what the wording in the policies and schedules

26 TRENCHLESS AUSTRALASIA DECEMBER 2022

Unforeseen weather events can have disastrous effects on the unprepared.

actually means, what events or losses are excluded, and how the policy applies to scenarios which are likely to impact a business.

“Most learnings are unfortunately gained through the experience of claims but by then it is often too late to ensure you are adequately covered or covered at all,” says O’Meley.

Contract works Contract works covers damage to HDD works and materials under the insured party’s care, custody and control during a project.

It is one of the more complex areas of insurance, but it can be a lifesaver for a business when an unforeseen event occurs.

Claims for loss or damage commonly emanate from events beyond the control of the contractor, including earthquake, landslide, subsidence, collapse, storm, rainwater, flood, tsunami or cyclone.

Factors to watch out for include: •C ontract value limit – the insurer will require a contract value limit to be set under the policy. This limit cannot be set with certainty especially in a growing business or where variations, such as extra overs for rock, come into play.

“If you win a contract in excess of the set policy limit, or have variations causing the contract value to exceed the limit, ensure that you

notify your broker with a view to achieving agreement for coverage by the underwriter (at no additional cost),” says O’Meley.

•B ore diameter limit – underwriters struggle providing cover over 500 mm, let alone in excess of one meter diameter bores.

“This is where you need the underwriter to have a good feel for the risk associated with the specific project and your business overall so that cover can be readily provided,” says O’Meley. “You also need to know whether your insurer has the capacity to insure larger diameter bores because finding an underwriter with the wording to allow it can be exceedingly difficult.”

•F ree issue materials – even if materials supply is not part of a works contract, if the materials are in the operator’s care and custody, works contracts can contain clauses making the materials the operator’s responsibility until installed.

“This means you are at risk for loss or damage.

Ensure you have cover for free issue materials and up to a value of the materials under your care and custody,” says O’Meley.

•A bove 26th parallel exclusion – insurers do not like the cyclone areas of Australia. If working above Gladstone, Alice Springs or Exmouth, operators need to ensure that this exclusion does not apply to them.

“If not, it’s a matter of going there at your own risk,” he says.

•F lood – drilling under rivers and low-lying areas will always have the risk of flood attached to them.

O’Meley says that it is necessary to ensure that a policy covers flood events and that that there is an effective flood risk management plan in place for the project.

“Also watch the 72 hour rule – if the flood extends over this timeframe then it can become more than one event triggering extra deductibles,” he says.

•P rincipal contractor project contract works policies – in cases where the principal contractor has in place contract works

HDD

insurance, which covers the work of its subcontractors, operators should not automatically assume they are adequately covered.

“Know what that policy covers and, in particular, what the deductible is. A $250 k deductible set for a tier 1 contractor is not especially useful in providing cover for a smaller subcontractor,” says O’Meley.

• Ground conditions – the extended La Niña event has made ground conditions less stable and caused the build-up of underground water levels. This can impact on HDD operations either directly or, where nearby other contractors’ works have water problems, “flow through” onto an operator’s HDD bores.

“In these instances, it’s about knowing not only your policy cover, but those of the other contractors on the project,” he says.

Equipment Equipment policies cover sudden and unforeseen physical loss or damage to the insured equipment. Policies also provide ancillary benefits such a financial protection for loss of revenue and increased cost of working.

Factors to watch out for include:

• Insured value – getting insured values close to a current market value, particularly on higher value equipment that is critical to the business, is essential.

“Having an agreed value under your policy is preferable on the proviso that it is at, or near, market value,” says O’Meley.

In the event of a total loss, having an agreed value will expedite the claims process as valuers will not become involved in the claim settlement process.

• Partial loss - in the event of a partial loss the insurer may compare the market value to the insured value. If there has been under insurance, then they may have a clause in the policy which allows a proportional reduction in the claim to allow for under insurance.

• Valuations – it is good practice to have current valuations of key equipment, especially in the present market where there is the impact of inflation, plus supply shortages, creating alltime high values for used equipment.

• Financial protection – this cover is for consequential loss that occurs if the equipment suffers damage during a flood event. The policy will set both the maximum amount and period of cover. If policies have reference to the average revenue derived over the last year by the individual item

of equipment, that amount will be low if utilisation has been low i.e., the benefit of this cover will be limited. In the case of the numerous recent eastern state floods, it can be up to three months before works can recommence.

• Tooling – equipment policies will not generally cover tooling such as drill pipes, collars, rock bits, reamers, core barrels, stabilisers, logging equipment and casings while in the bore hole.

“In case of flood, make sure you get them out before the waters arrive,” says O’Meley Maxibor is fortunate that it has been able to establish, over time, exceptionally good working relationships with its insurance broker Luke McMahon of Bespoke Insurance Group.

McMahon has provided a truly knowledgeable and professional link into the underwriters, enabling the full spectrum of Maxibor’s insurance policies to provide good coverage of the business.

The company’s go-to valuer, Tony Taylor of Blue Gum Asset Advisory, has also helped ensure the value of its equipment has been at or near market value in a volatile market space.

TRACTO hosts Australasian contingent at Europe’s largest construction event In October, TRACTO Australia hosted a group of contractors and partners from Australia and New Zealand at one of the world’s largest construction events in Munich, Germany.

The group of almost 20 people made the pilgrimage to Bauma 22, and were in attendance to see the manufacturer’s launch of its latest horizontal directional drilling (HDD) machine, the GRUNDODRILL ACS300.

auma is the one of the world’s leading trade shows for construction equipment and machinery. This year the event boasted approximately 3200 exhibitors from 60 countries, while nearly 500,000 visitors from more than 200 countries descended on Munich, half of which travelled internationally to get to the event.

Fostering partnerships TRACTO Australia, led by Managing Director Jeff Rose and Sales Manager Daniel Toms, hosted a number of contractors and partners from Australia and New Zealand who had travelled over for the event.

Rose says the trip was an opportunity to further develop the relationships the Australian subsidiary has with its clients.

“As a German manufacturer, Bauma is TRACTO attended Europe’s largest construction event.

The new GRUNDODRILL ACS300 provides intelligent HDD solutions.

TRACTO’s most important event anywhere in the world,” he says.

“First and foremost, it was exciting to have some of our key partners from Australia and New Zealand here to see the event, and the launch of the machine in person.

“However, it was also an opportunity for us to further develop those relationships, ensuring we have a deep understanding of their needs, enabling us to determine how best to support them and the unique challenges they face.

“We also had key members of our engineering and design team, and service and support at the event as well, which gave our partners a unique opportunity to speak directly with the people who

know the whole range of TRACTO machines better than anyone.”

During the course of Bauma, the manufacturer hosted a several networking events on its stand, giving the Australasian delegation an opportunity to learn more about the machines and also form relationships with TRACTO’s international team.

As the local agent for fellow German manufacturer Prime Drilling, the event also enabled the visitors to learn more about Prime’s range of HDD machines as well as the company’s wider team.

Prime Drilling: Putting the customer first Prime Drilling has earned a reputation as a supplier of high-precision horizontal directional drilling equipment not only in Australia but across the world. Its drilling rigs are made from the highest quality materials, and developed and designed to be robust, reliable, and low maintenance. made hardy, reliable rigs that have boasted lifespans of at least 40 years – the equivalent of approximately 40,000 hours of use.

“With the bigger rigs, our customers have very specific needs. They’ll come to us with a long wish-list and our designers work very hard to meet those demands,” says Kiesow.

Prime Drilling has perfected the design of its compact drilling rigs.

S

ince its establishment in 1999 Prime Drilling’s status has grown, establishing the relatively small company as a notable name in the global horizontal directional drilling (HDD) industry.

Mutual growth Prime Drilling began as a manufacturer of custom built and designed HDD rigs, allowing the company to showcase its ongoing commitment to meeting the specific needs of its customer base.

As Prime Drilling demonstrated that hard work and reliability makes the company shine, the satisfaction of its customers ensured that it could grow alongside operators in the HDD industry.

International Sales and Service Director, Ralf Kiesow, has watched Prime Drilling grow since he started with the company 18 years ago.

“Over time, as our reputation and our expertise grew, there became more of a demand for bigger machines,” says Kiesow.

He explains that there was a point in Prime Drilling’s history where it realised that it could 30 TRENCHLESS AUSTRALASIA DECEMBER 2022

tap into the open market for larger equipment – including its 80-tonne compact unit. It was only natural that the manufacturer would grow to meet those industry needs.

“From that realisation, we figured out that we could produce a standard model for this unit that could then be customised to suit the needs of specific clients,” says Kiesow.

Kiesow says a number of Prime Drilling’s products are gold standard and range from smaller compact units to the huge 150-tonne rigs that the company manufactures.

Built to last The longevity of the manufacturer is due in part to the careful consideration that is made with regards to the availability of parts for its customisable rigs. By making its machinery compatible with a range of globally available standard parts, Prime Drilling ensures that clients can easy acquire replacements without the challenges usually involved in repairing custom rigs. The need to replace parts on Prime Drilling’s machines is not as common as operators think. The manufacturer has

The proof is in the product Prime Drilling’s PD 45/19 CU is a consistent best-seller from its range of compact equipment. The machine demonstrates great efficiency and a small footprint, setting the standard for other compact rigs in the HDD industry.

It was designed with specific attention to optimising weight and size, keeping the cost of transport and set-up to a bare minimum.

Its 205 kilowatts of power and 19,000 Nm of torque makes the PD 45 the rig of choice for customers who need guaranteed fast, economic, and uncomplicated operation.

Its CAT 7.1 ACERT motor features the latest emission standards and adjustable cooling systems, minimising fuel consumption and further optimising efficiency, while its feed and pull back functions for the hydraulic power rotary head are carefully driven by an internal rack and pinion feed system.

Power in people Prime Drilling has grown steadily in small, deliberate steps. According to Kiesow, part of the reason for this is that the company has been sure that it is doing everything it can within its capabilities before expanding. The company also makes sure it’s investing in the right people.

“We’re very happy with the people we have,” says Kiesow. “Most of our people have been there since day one. Our people love what they’re doing; they live and breathe HDD.” With its expertise in the HDD industry, and the focus on getting each step of its operations right, Prime Drilling has earned its place as a global manufacturer.

M Tucker & Sons turns worksite waste into valuable resource Civil and trenchless drainage specialist M Tucker & Sons is expanding its services it can offer customers and tackling no-dig waste at the same time.

I

n the trenchless industry, it’s well known that no-dig drilling (NDD) and horizontal directional drilling (HDD) are the methods of choice on projects that aim to minimise disruption and impact on communities and the environment.

The waste produced by these operations is one thing that has been consistently overlooked.

M Tucker & Sons is now set up to take what most operators consider waste and is transforming it into a useable product that can be used to give back to the community – concrete.

Disposal of waste from NDD and HDD isn’t free. There is a price associated with its collection, as well as fees at the landfill and the cost of trucking it to be thrown away.

Beyond that, there is an environmental cost. In a world where operators are becoming increasingly aware of sustainable practices, reusing waste products is as good as it gets.

A win-win situation When the company owner Mark Tucker

32 TRENCHLESS AUSTRALASIA DECEMBER 2022

came up with the idea, the focus was on landfill diversion. While NDD and HDD waste contains vegetation and other contaminants, it also contains all the crushed rock, sand and silt that can be repurposed.

By taking the waste product from work sites to the plant that the company set up at its headquarters in Mount Evelyn, east of Melbourne, the company is able to save money by refining it into concrete that could be transported back to the worksite. The product can be used to construct pits for construction projects, or even for pouredconcrete furniture, planter boxes, and community pathways.

“The goal is to team up with major construction projects to help them meet their sustainability goals, and to keep costs down. Manufacturing concrete also means we don’t have to buy quarry products, which reduces the carbon footprint of a project even further,” says Tucker.

The company is using the concrete on its own work sites, but Tucker says there is more than enough that can be used by one company.

The process M Tucker & Sons is able to utilise waste not only from NDD and HDD projects, but also storm water waste, excavated material and waste pulled from gutters by local councils.

The waste-turned-resource comes in under an EPA licence where it is registered, stored, and then tested to determine its contents.

Once that’s done, the material pushed through a CDE G:MAX wet recycling system where it is treated and separated into real waste (plant matter and rubbish) and useable material – clean stone, sand and water.

Rocks are then sized so they can be used in different forms of concrete.

“We understand what we have. We have the data to show that we’re manufacturing structural concrete,” says Tucker.

An added benefit is the company doesn’t have to introduce water to the cleaning process. The water from the mud that comes in as waste is treated with special polymers and chemicals that help the solids settle during the cleaning process and can be collected and reused.

With increasing amounts of water

HDD

being generated, M Tucker & Sons is now undertaking studies to determine how excess water can be made safe to use as part of the concrete itself, further increasing the amount of recycled material used, which is already 70 per cent.

Able to meet all needs Tucker says that the entire operation is scalable, allowing the company to increase the amount of waste it processes, or

concrete it generates.

“If the project is big enough, we can set up on a temporary footprint, put a dewatering system there and create the product, the concrete, on site,” Tucker says.

He says that, especially with the prevalence of no-dig options in urban areas with a lot of foot traffic, he would like to see concrete paths underfoot that came from the invisible projects that, despite best efforts, do have some impact on the community.

“It’s how we can give something back,” says Tucker.

Equipped with undeniable proof of the viability of its process, M Tucker & Sons can help industry operators across the civil and construction industry ensure the sustainability of their operations.

Vacuum excavator becomes tool of choice in council fleets Vacuum excavators are the often unsung hero of the trenchless technology world, quickly and effectively moving soil when needed so that horizontal directional drilling can take place. But now, local governments across Australia and New Zealand are discovering a multitude of uses for vacuum excavators.

pressure water with an air vacuum, vacuum excavators can remove significant amounts of earth with minimal damage.

Vacuum excavators started as support

machines for horizontal drilling operations, locating existing buried utilities prior to drilling and managing the drilling slurry. This role continues to gain prominence as the network of underground assets expands, particularly with the advent of the National Broadband Network and buried distribution power lines.

However, a range of uses beyond the traditional trenchless market are ensuring that councils which invest in a vacuum excavator have their machine in constant use – making it a valuable addition to the fleet.

These versatile tools excel in applications that range from digging around utilities to efficiently excavating small holes, cleaning up storm drains, assisting with water main breaks and much more. The vacuum excavator can be used to replace more labour-intensive and

inefficient methods of working.

“In Australia and New Zealand, communities are becoming less tolerant of works that impinge on their daily lives. They expect local governments and contractors to utilise construction methods that reduce the area required to carry out any works,” says Jeff Lawson, Vermeer Australia’s General Manager of Sales.

“They also expect their local government to employ construction methods that are sustainable and minimise the damage caused to the surrounding environment.

“We’re also finding that councils are becoming more aware of the potential safety risks that come with digging trenches, or excavating close to dangerous environments like busy roads. They are looking for automated solutions which keep their employees out of harm’s way, and vacuum excavators are just one example of this.”

Non-destructive digging helps protect sensitive environments Vacuum excavators are becoming the preferred method to excavate in many applications where existing infrastructure exists. Excavating

footings for poles, signs and fence posts has become common.

One task that is often a challenge for councils is digging up and replacing existing utility poles that have either been damaged or exceeded their useful life. Using an excavator or backhoe to dig up the poles without disrupting surrounding utilities can present a difficult challenge. The vacuum excavator is well suited to this task.

It can dig around the pole, even when buried utility lines are tied into the pole.

Vacuum excavation excels in digging tasks where either a small hole is required or there may be hidden infrastructure. Holes can be dug for new trees and stumps can be removed around existing utilities.

Vacuum excavation can also access tight spaces. It allows councils to dig short runs where a backhoe may struggle with access.

Vacuum excavation also proves useful for removing roots and debris around water meters and valves.

Vacs clean up Many of the applications for vacuum excavators don’t even involve digging. The vacuum technology can be used in clean-up operations

Vacuum excavators excel in a range of applications in the trenchless industry.

and aid in water main repair.

When water mains break and a pump can’t keep up, vacuum excavators can handle the job.

They also prove useful to exercise water valves and jet sewer pipes when properly equipped.

Vermeer manufactures a range of vacuum excavators which save time, labour and material handling costs. Whether it’s potholing for a fibre installation or supporting a HDD rig, Vermeer has the vacuum excavator for the task.

With units ranging between 400 and 11,000 litre spoil tank capacity and the CFM to match, we have your vac ex requirements covered.

Pace Drilling proud to partner with horizontal drill specialists Ditch Witch CEA Ditch Witch CEA is helping New South Wales horizontal drilling company Pace Drilling with a range of construction challenges.

F

ounded in 2004, Pace Drilling has grown to be one of the most respected and reliable horizontal directional drilling (HDD) specialists in New South Wales.

With a track record of cost-effective and quality methods, as well as continually meeting the challenges each construction job requires, Pace Drilling has the expertise and equipment to get the job done.

Pace Drilling has worked on a multitude of projects involving different conditions and challenges including motorway crossings, river crossings, rail corridor crossings and suburban street works.

Aaron Pace, Pace Drilling Primary Driller, has worked in the family business for over a decade. Upon completing his education, he joined the company to continue the work his father started.

“Since then, I’ve learned a lot,” he says. “I now operate two main machines, the Ditch Witch AT30 and AT60 all-terrain drill rigs.”

“The role of a driller includes many technical aspects such as monitoring the drill head and

following bore designs. These skills are ones that I’ve built over several years and I’ve been fortunate enough to have been able to learn from the founder and father of the company, Simon Pace.”

Pace Drilling initially used a relatively small drill rig, which was rated at 20,000 pounds of pullback and was not rock capable, in 2004. Subsequently, the company was limited to completing smaller bores to a maximum distance of 100 m.

Over the years the business has been able to upgrade to newer and more capable equipment. Now the company operates with two drill rigs – the Ditch Witch AT30 and AT60 – both of which are all-terrain machines and rock capable.

The AT30 drill rig is suited for smaller bores up to 150 m in length and at a diameter of 500 mm, pending ground conditions. The AT30 rig is best for tighter areas where a smaller footprint or sharper bend radius is required.

Pace Drilling has utilised the AT30 on a range of projects including the Macquarie

Founded in 2004, Pace Drilling has grown to be one of the most respected and reliable horizontal directional drilling specialists in New South Wales.

Park stage 3 upgrade on behalf of Georgiou, the Nepean Hospital Underbore, and the M4 Motorway Crossing.

The AT60 drill rig is well suited for much larger projects. Pace Drilling is currently completing bores of up to 450 m in length, with their drill, and are capable of larger diameter bores pending ground conditions.

Pace Drilling has used the AT60 on projects such as the Western Sydney Airport upgrade on behalf of Sydney Water and Quickway’s Sydney Metro West 33Kv Underbore Crossing.

Optimised for industry-leading performance and productivity when drilling in hard rock conditions, the Ditch Witch AT30 is designed with an advanced version of the proven Ditch Witch all terrain drilling system.

The updated, two-pipe system boosts power to the bit—33 per cent more torque than the competition. The drill leverages the next-generation features of the JT40 model so operators get increased jobsite cycle times, improved durability, and greater control.

“The power enabling works for the Sydney Metro located in Rozelle on behalf of Quickway stands out as an especially proud moment for the team,” says Pace. “The works were completed across Victoria Road and were a dual bore, with each bore being large in diameter and containing multiple electrical conduits.”

Pace Drilling has been working with Ditch Witch CEA for over 16 years, having purchased its first drill rig in 2007. Since then, Ditch Witch CEA has proved its dedication to delivering the highest level of product support to its customers.

Employing factory-trained sales and service specialists who are dedicated to supporting clients and all machinery requirements, Ditch Witch CEA is equipped with the expertise and knowledge to help businesses like Pace Drilling develop a strong reputation in the industry.

“Ditch Witch CEA is always willing to provide on-site service whenever called upon to ensure completion of the project is at a high safety standard,” says Pace. “CEA has proved

professional and reliable service.

“We manage our sites, our work and documentation to a very high standard,” Pace says. “We ensure our checklists, inspection test plans, methodologies, grouting and management plans and plant and equipment records are meticulously kept. It seems like a little thing, but that attention to detail is key.”

Looking to the future, it seems the only way to go is up – the company has been awarded

that we always have their support as a Ditch Witch owner; all the way from the dealership to parts and service.

“The AT60 has proven over the years to be both powerful and reliable, providing cutting edge technology. The capability to drill and steer in hard rock has assisted us over the years to achieve many successful bores.”

Pace Drilling is accustomed to putting in the hard work and dedication needed to provide

several projects with clients including the Botany Duplication project and the South Erskine Zone Substation.

These projects are yet another exciting chance for Pace Drilling to flex its expertise and prove that this family owned and operated company is not to be underestimated.

“In the future, I see Pace Drilling keeping our high work standard and ethic by achieving our clients’ needs within budget and as safely as possible,” says Pace.

“As a company, Pace Drilling is aiming to continue becoming more sustainable and environmentally friendly. With new and innovative technologies arising and evolving, Pace Drilling is always trying to stay ahead of the trend when it comes testing these new technologies to help reduce our carbon footprint.”

Supporting the company during this exciting time, Ditch Witch CEA is committed to continuing to provide Pace Drilling with expert advice on what equipment best suits the company’s needs and ensuring each piece of machinery is of the highest quality.

The Switcher only requires one pass for a total clean.

Sewer cleaning just got easier Drainchem is the provider of StoneAge Tools’ cutting-edge nozzle range – the Magnum series.

S

toneAge Tools, the makers of one of the world’s best sewer jetting tools, have developed a high-spec nozzle range called the Magnum series.

The series showcases a number of key features including: • ½-inch to 1-1/4-inch inlet options.

• Suitable for recycled water.

• I ncreased service life of 1600 hours between seal change.

• S uitable for 150-900 mm pipe (depending on pump capacity).

• Operating pressures from 83-345 bar.

• Operating flows from 50– 450 lpm.

• Reduces toilet blow outs.

• Increased pulling power and cleaning power.

Versatile and powerful The Warthog Magnum Switcher head is two powerful tools in one. The most significant design change from the classic model is that the Switcher has two sets of jets that operate independently.

One set of jets has one forward and several rear jets (the number of which depends on flow and pressure of the operator’s jetter) and is used to jet up the line, punch through the blockage and reach the upstream manhole.

This angle change increases the thrust or pull of the nozzle when jetting up the pipe, allowing operators to reduce flow and pressure while jetting up the pipe. Doing so reduces the likelihood of breaking a water seal at the house or blowing the toilet.

If the grade is very steep or a very long run, then increasing the pump speed will deliver 42 TRENCHLESS AUSTRALASIA DECEMBER 2022

much more power.

Once the nozzle reaches the upstream manhole the operator simply reduces the water pressure to below 500 psi and then increases the pressure back to operating pressure. The Switcher will change the direction of water flow from the front and rear jets to the side cleaning jets.

The angle of the cleaning jets is just below 90 degrees which, along with a much shorter distance of travel from the nozzle to the pipe, increases impact pressure on the debris in the pipe and hugely increases cleaning power.

Easy to use The operator can easily tell if the Switcher is in jetting mode or cleaning mode, as it will not propel up the pipe if it is in cleaning mode.

In jetting mode, the hose will pull strongly, allowing the Switcher to be used easy and intuitively.

The Switcher will clean faster – only one pass

is required for a total clean. Drainchem states this results in less water usage, reduced cleaning time, fuel consumption and cost, less wear and tear on valuable jetting equipment, and less wage costs and, more productivity.

The Warthog Switcher tools are one of the most flexible controlled rotation sewer cleaning nozzles on the market. The Switcher is designed to successfully remove obstructions in pipes ranging from 150-900 mm and to be used with at flows from 50-450 lpm.

The product also features a range of hose connections in ½-inch to 1-1/4-inch.

As two tools in one, the Switcher is the only tool a sewer jetting truck needs. Drainchem can assist customers in increasing cleaning power without the expense of purchasing a bigger truck.

Smart Lock makes short work of sewer drain repair in Hong Kong When the Hong Kong Drainage Services Department identified a badly damaged pipe, it was Smart Lock’s sleeve solution that empowered contractors to successfully rehabilitate the damaged section.

The Smart Lock solution ticked all the boxes for the complex project.

C

hallenging from the start The concrete drainage pipe was aged, partially collapsed, and had sustained severe damage from hydrogen sulphide attack.

Freyssinet Hong Kong was engaged by the Department to carry out a DN825 repair on the pipe. It was a challenging task from the start, with an access shaft required to commence the rehabilitation and other associated works that needed to be done on the important drainage asset.

Time was of the essence, as the sewer flow could not be reduced for any extended period of time. Engineers from the contractor company required a structural sleeve that would allow them to complete the job and was able to facilitate a fast-as-possible installation so that the sewer flow would not be greatly impacted during the work.

Adding to the growing list of requirements to execute the work, the proposed air packer needed a full flow through in the event that a short capacity drop was required upstream of the works. This flow through would need to be to be substantial.

Excellent execution After the necessary technical consultation, the Smart Lock sleeve solution was proposed by distributor Astra Syntech as it met all the criteria to successfully complete the works. The contractor was briefed, and the Smart Lock

44 TRENCHLESS AUSTRALASIA DECEMBER 2022

was accepted as the best solution. The job was commissioned shortly after.

Freyssinet’s sewer maintenance staff are accomplished with fibreglass silicate resin patching and experienced in the correct use of an air patch packer. The Smart Lock installation methodology is a close match to the teams’ existing skill set in the field of point repairs.

All installers require accreditation to purchase a Smart Lock. With time an important factor in the execution of the work, Smart Lock’s technical support team were able to remotely provide training in the use of the product for the crew and the manager who

would be undertaking the work.

The installation took place in normal working hours in September 2022. The depth of the access shaft required a crane to lower the installation equipment and the 825 mm stainless steel sleeve. This was not a job for rope-lowering and retrieval.

After all pipe surfaces had been cleaned using high pressure water jetting, the Smart Lock wheeled-installation-trolley was set up and a trial placement was carried out to gauge position and pipe entry clearances.

With everything in order, the Smart Lock sleeve was positioned on the trolley at transport holding pressure. The trolley was pushed into the pipe and centred on the pipe defect. An installation air pressure of 35 psi was applied to the Smart Lock via the packer.

In just a few minutes the defect was successfully rehabilitated, and further reinstatement works were able to proceed.

This was the first project for the Australianmade trenchless solution outside of Australia and New Zealand.

The installation was observed by the drainage authority engineers at Hong Kong Drainage Services Department and the Freyssinet contractor management team and deemed a favourable outcome for all those involved.

The inversion process for the NordiFlow liner into the AC Pipe DN 400 at the treatment plant.

T

oday, similar to Australia, thousands of kilometres of asbestos cement (AC) pipes are still being found in Europe, with the rehabilitation solutions for this aging material still being limited.

technology (Class A system) is independent from the AC pipe and able to carry all internal loads (pressure and vacuum), as well as all external loads (soil, ground water, surge, traffic loads available for DN 150 -DN 1400),” Luksch says.

“R-tec Close-Fit Liner systems, pre-folded PE Pipes, are factory made Class A systems – allowing structural liners to carry all loads (DN 150-DN 400).”

In 2021, NordiTube Technologies SE and its Hungarian installation partner Agriapipe Kft were awarded a 5.5 km of DN 400 AC sewer water main, running from a treatment plant to a reservoir.

the final decision for the end customer easy.

Luksch says as an international tender, to be able to rehabilitate the AC pipes, the pits and pipes needed to be prepared so no AC fibres could leave the area.

“Therefore, the pipe section which had to be taken out needed to be in a sealed environment / tent, which operated with a low negative pressure and a special filter system that could catch all loose fibres,” he says.

“The workers who were in contact with the material needed to have special protection equipment and masks. All AC parts needed to be packed in special sealed bags and treated by a certified company.”

The host pipe ends had been prepared with a piece of steel pipe (or flange) which had the same ID as the AC pipe. These parts were essential to fix the liner end seals.

Luksch says 50 per cent of the lining had

installation lengths greater than 250 m and had been done with the NORDIFLOW pullin liner, including an an external coating.

However, the other 50 per cent were installed with the NordiFlow Inversion System in combination with a pre-liner.

The project was successfully executed and the new stand-alone NordiFlow Liner is now in service.

REHAB & REPAIR

Ageing pressure pipelines come to life with Primus Line’s innovative trenchless technology Kilometres of ageing water and pressure sewer pipelines across Australia and New Zealand are in need of renewal. Until recently, some of the more challenging pipelines have left asset owners scratching their heads and in need of a practical, affordable, long-term solution.

rimus Line, a flexible liner reinforced with aramid fabric, is getting buzz for all the right reasons. The tried and tested lining technology provides a practical, high-quality lining solution for ageing pressure pipelines that is both environmentally friendly and cost-effective.

Project Manager at Interflow Fergus Meyer understands the challenges many asset owners face when tackling the problem of ageing infrastructure.

“A lot of projects have been sitting in too hard baskets for years, waiting for the right technology and delivery partner to come along,” he says.

“Environmental constraints, budget limitations and delivery risk are all factors that can stop a project getting off the ground.

“The key is engaging suppliers early and coming up with solutions together. So is

REHAB & REPAIR

keeping an open mind to alternate proposals at the time of tender. This can really open the door to affordable, and eco-friendly solutions, like Primus Line.”

Interflow has partnered with Primus Line to provide the innovative system to the Australian and New Zealand market. Leveraging their fiveyear exclusivity agreement, the two companies have made a significant impact throughout the year, rehabilitating some of Australia and New Zealand’s most challenging pressure pipelines.

Primus Line in action Earlier in 2022, Interflow was given the challenge of rehabilitating a deteriorating section of steel water pipe supplying the remote mining town of Paraburdoo, Western Australia.

The pipeline runs through an area of environmental and cultural significance, so a non-invasive solution was needed. Using Primus Line, Interflow relined a kilometre of watermain in a single pull, meaning no digging or disturbance along the alignment.

The project took just over a week and only a single truck was needed to transport the spool of liner and associated fittings – a significant benefit when the nearest major city is 1500 km away.

More recently, Interflow used Primus Line to rehabilitate and recommission two out of service sewer mains in Sydney’s Inner West.

Limited access to the alignment and the

Mt Cole Pipeline renewal project.

presence of both vertical and horizontal bends ruled out conventional solutions like slip lining and pipe bursting.

Primus Line handles bends up to 45 degrees with ease making it the ideal candidate for the job. Interflow returned the two mains to service with minimal disruption to the busy residential and commercial community.

One of Interflow’s more challenging projects Primus Line installation in progress.

in 2022 involved 1.4 km of pipeline that transports raw water from a dam to a nearby town. Located deep within a state park and traversing steep and rocky terrain, replacing the pipeline would have been a costly exercise with unacceptable risk to the environment.

The rugged location left little access to the alignment of the pipe. Having access only to the ends of the line, Primus Line was installed in one continuous pull. This marked the longest single pull of Primus Line in Australia to date and opens the opportunity for longer pulls of a similar nature in the future.

The project was recently recognised as the winner of an Infrastructure Project Innovation award from the Australian Water Association in Victoria.

Ready to support your future needs There is a growing need for asset owners to look for innovative ways to address issues like rising costs, resource availability and the need to support net zero targets.

As Interflow moves towards 2023 and beyond, innovative technology like Primus Line presents an exciting opportunity for the water industry to overcome these issues and extend the life of ageing infrastructure for decades to come.

With local supply right here in Australia, Interflow is ready to support high priority projects without supply-chain setbacks. Speak to them today about your pipeline infrastructure problems.

MICROTUNNELLING

Collaboration helps minimise community disruption.

Rob Carr invaluable on South Melbourne sewer project Microtunnelling contractor Rob Carr is the tunneller of choice in the Fulton Hogan Delplant Beca joint venture’s (FHDB) sewer works beneath the streets of South Melbourne on behalf of South East Water.

T

he Hanna Street Stage 1 capacity upgrade project is part of the larger South Melbourne Sewerage Capacity Upgrade being undertaken by Melbourne’s water utility, South East Water.

Proactive and necessary Population density in South Melbourne is increasing as time goes on. The existing sewer system is expected to experience significant strain as this happens. In addition, the system needs to be proofed against future extreme weather events in order to protect the South Melbourne catchment.

Josh Sneath, Rob Carr’s Project Engineer for Hanna Street Stage 1, confirms these concerns with a practical view from the ground level.

“With the number of high-rises going up in the surrounding area, we are getting ahead 50 TRENCHLESS AUSTRALASIA DECEMBER 2022

of the strain predicted for the current sewer system,” Sneath says.

Not without challenges Work commenced in late September 2022, with Rob Carr beginning 270 m of microtunnelling and installing glass fibre reinforced plastic (GRP) pipe for the new network.

The project also requires two segmental shafts, one with an internal diameter (ID) of 6 m, and the other a 4.5-m ID. “There’s also an eight by five metre pile shaft,” says Sneath. “We’re constructing it over the South Yarra main, where we’ll eventually install a GRP manhole.”

The pile shaft will connect up the branch sewers that Rob Carr is constructing and tie them in with the South Yarra Main, bolstering

the whole network.

The work is not without its challenges, of course. But Rob Carr is no stranger to delivering on technically difficult jobs.

With the number of buildings going up in the area, as well as other complications surrounding the location, the company is still delivering well on the project.

“We’re working in a tight community space, so we have to keep our footprint as small as possible,” says Sneath.

Teams have managed to keep most of the roads in the area open with at least one lane of traffic continuing to minimise the impact on the surrounding community.

The tie-in to the South Yarra main will occur via a 2-m ID brick drain which, according to Sneath, is likely to be the most difficult part of the overall project.

MICROTUNNELLING

The Hanna Street Stage 1 project demonstrates what can be achieved when operators are able to work closely together.

This sentiment is echoed by Colm Dickey, Rob Carr’s Construction Manager for the project.

“The sewer flow has to be kept live during the tie-in work and while we’re building the manhole, which obviously presents some technical challenges,” says Dickey.

In order to complete the work, the teams have to install a flume pipe while the sewer is live.

“There’s some tricky brick removal

sequencing involved in that, we have to be very careful about which brick we remove as we go,” says Dickey.

Once the bricks are removed the flume can be installed and Rob Carr’s teams can get to work constructing the manhole.

Constant teamwork is the key to success Completing a major project in such a heavily populated area is a difficult ask, but one that has succeeded largely because of Rob Carr’s

long proven track record of teamwork and its focus on collaboration and communication with project partners.

Dickey has not worked directly with FHDB before but has witnessed Rob Carr’s strong relationship with the JV first-hand during his work on the Hanna Street Stage 1 project.

“The collaboration really has been phenomenal,” he says. “We’ve worked through any and all issues that have arisen, from executing the tunnelling to the technical side of things – like monitoring ground and water conditions.”

“It’s an interesting project, with a lot of collaboration needed to keep it moving,” says Sneath. “Tie-in works are on track to start in January, and we should be finished with stage 1

by April or March next year.”

The Hanna Street Stage 1 project once again demonstrates what can be achieved when operators are able to work closely together with a unified goal, a virtue that Rob Carr explicitly shows time and again as the company assists in future-proofing Australia’s infrastructure one successful project at a time.

s part of a Water Main installation project situated in Badgerys Creek New South Wales, contractor Quickway, used kwik-ZIP’s HDX-90 spacers to facilitate the slip-lining of an 813 mm outer diameter (mm OD) Steelmains Sintakote carrier pipe over a 180 m run.

The installation was undertaken by Quickway, on behalf of Sydney Water, and the West Region Delivery Team (WRDT). kwik-ZIP spacers were installed at 2 m 52 TRENCHLESS AUSTRALASIA DECEMBER 2022

intervals throughout the project as per Sydney Water’s specifications. Carrier pipe weights were significant at 240 kg per m empty and approximately 700 kg per m when in service.

Having grown steadily over the years since its beginning, Quickway has become a trusted contractor within the trenchless industry and has established a solid reputation for delivering integrated project solutions. The company prides itself on delivering highquality service from concept to completion.

“kwik-ZIP spacers provided both protection and cover for the carrier pipe and enabled us to complete a successful underbore installation,” Matthew Macinnes, Project Engineer for Quickway, says.

The HDX Series used on location at the Badgerys Creek site has a unique load sharing design which maximises the load bearing capacity of each runner and reduces point loading. The simple and efficient installation process does not require any special tools.

MICROTUNNELLING

kwik-ZIP’s large range of spacers caters for different carrier and casing pipe size combinations as well as providing flexibility to deal with project alterations.

Furthermore, the HDX casing spacer comes in four handy runner heights: 38 mm, 65 mm, 90 mm and 125 mm.

The varying runner heights for the model ensures that pipeline installers are able to handle a broad range of carrier pipe outer diameter and casing inner diameter combinations. Additionally, this grants installers the ability to customise pipe position for grade control, otherwise known as centring.

Manufactured from high grade thermoplastic, kwik-ZIP casing spacers and centraliser products are used and recommended by pipeline and civil contractors as well as commercial plumbing companies, water authorities, water well drillers and international engineering firms throughout Australia. kwik-ZIP spacers have no metal parts and are made from kwik-ZIP’s engineered thermoplastic blend that is flexible and extremely tough. Its low co-efficient of friction also minimises the installation forces for large bore pipes.

kwik-ZIP maintains a focus on price effectiveness, simplicity, and rapid onsite assembly, to ensure that their systems deliver significant cost, time and operational advantages to its customers.

Capable of handling steel, DICL, HDPE, concrete and MSCL carrier pipes at a wide range of sizes, kwik-ZIP’s HDX Series minimises potential damaging vibration and movement transfers from the outer casing to the carrier pipe via innovative suspension and dampening technologies. Likewise, kwik-ZIP’s spacers contain no lead content or metals– ensuring they are fully compatible with all potable water applications and resistant to corrosion and rust. The systems are now used extensively in production well completion, horizontal directional drilling, rock bolt and anchor centralisation and trenchless pipeline installations across Australia, New Zealand, the UK and the US. kwik-ZIP spacers are one of the only Australian-owned products of its kind on the market and the HDX Series are one of only two spacers (kwik-ZIP’s HDXT is the other) which have been certified and approved by the Water Services Association of Australia against its Product Specification WSA PA 324 Casing Spacers.

Fighting against the elements: preplanning for success in Townsville Heading into the wet season in northern Queensland, Edge Underground – part of OptionX Group – were working against extreme heat and flash flooding on a microtunnelling project to complete three lines, with one under a major state highway.

W

hen planning for the success of a major project, time, costs and weather are usually the main contributors to challenges. However, for Edge Underground fighting against the elements and upcoming holidays, planning played a major role in it performing its best and getting the job done on time.

Edge Underground was subcontracted to complete three micro-tunnels in Townsville, Queensland, partnering with Mendi Constructions, a wellknown local business. The job required a 450 DN, 500 DN and 600 DN concrete enveloper pipe to be installed – the small two pipes under one road, and the biggest and longest pipe under the Bruce Highway.

Difficult weather conditions Stuart Harrison, CEO of OptionX Group, says that going into the project the team knew that there could be challenges due to the extreme heat. The timing of the project, he says, meant that Queensland was heading into the wet season, presenting the team with the risk of flash flooding.

As the team was getting started on the project to install the 450 DN pipe, the worstcase scenario happened - three days of flash flooding stopping work before they were able to get momentum on the project.

“The flash flooding really set the foundation for understanding the need to get the shaft prepared for all weather and assume and plan for the worst as that will definitely allow you to perform at your best,” says Harrison.

“With the first shaft we had to make some compromises, and in this industry, whenever a compromise is made, it eventually catches up to you during the project. If it doesn’t catch up with you, you’re very lucky.

“We don’t like to rely on luck to perform well, so we pre-plan and manage the risk in order to ultimately be able to provide a highend final product.”

Harrison says the flooding made the job more complicated and increased the scope of work and timeframe to complete it.

However, with the lessons learned from line one, the team were able to complete the pilot and ream line two without any problems.

“The bore process was a total of two days of work, which was amazing considering the volume of material,” Harrison says.

Edge Underground has now completed a number of successful jobs in Townsville and the surrounding areas.

54 TRENCHLESS AUSTRALASIA DECEMBER 2022

MICROTUNNELLING

“And like all the jobs we complete, the pipe was installed within millimetres of the required grade.”

Edge Underground is the contractor of choice many installation of sewer and water pipelines across Australia.

Tackling challenges As well as difficult weather conditions, the team was presented with delays from the Christmas break and changing ground conditions midbore.

Harrison says the timing to start bore three was in the lead up to the Christmas break, so there were going to be several days where work wouldn’t be taking place. However, the project was finished well within the timeframe.

“There was a concern that maybe we shouldn’t start before Christmas, but we felt we had the ability to get it done and that if we started on Wednesday, we could finish it by Thursday night. This would be a great outcome for a 600 DN concrete enveloper pipe with an 800 mm bore,” says Harrison.

“It did get a bit complicated when we launched on Wednesday as we found there was a change in ground conditions mid-bore. It went from hard consolidated to more alluvial, and the alluvial layer was allowing high water flow across the compacted clay – which wasn’t noted in the geotech.

“However, with the AXIS laser guided boring system we can adapt the setup to best suit conditions, so we were able to readjust our setup and complete the pilot line on Wednesday, allowing us to start reaming Thursday morning.”

Lending experience Harrison says it can be hard in projects such as these to guide contractors with little experience with microtunnelling to make good decisions that reduce risk without being perceived as arrogant.

“When we feel it is necessary for the project, we try to highlight the need to spend a little more money in advance rather than pay heavily throughout the construction project,” Harrison says.

“And we saw this in action with this project; bore one was undertaken with the pay-aswe-go approach but bore two and three were quite seamless due to the pre-planning and commitment from everyone to understand the risks and minimise them so the project could be completed in the short timeframe leading into Christmas.

“To everyone else, bores two and three appeared to be uncomplicated but in reality, there was a lot of work that went into their smooth completion.”

Edge Undergound specialises in the installation of gravity sewer mains using installation techniques including microtunnelling, laser boring, auger boring and thrust boring.

Aussie Trenchless is committed to pioneering state-of-the-art solutions and furthering business in the trenchless industry.

Aussie Trenchless has the future of pipe rehabilitation solutions sorted Aussie Trenchless has been passionate about progressing future infrastructure opportunities and accomplishing superior outcomes since it was founded in 2014.

A

ussie Trenchless Director Chris Meredith and the team are committed to pioneering state-ofthe-art solutions and furthering business in the trenchless industry. As part of that innovation, the company continually offers a wide range of unique products both in Australia and internationally.

Aussie Trenchless’s SRP-EXP Spiral Lining System is designed to rehabilitate pipes from DN150 to DN1200 using a selection of six different sized profiles. The SRP-EXP system is a close fitting structural spiral ribbed PVC trenchless pipelining system.

Aussie Trenchless believes repairs using traditional civil open cut methods are far too costly and disruptive on communities.

58 TRENCHLESS AUSTRALASIA DECEMBER 2022

The SRP EXP sizes range from a profile type E7-050-5 for DN150 to DN250 pipes, E9-085-6 for DN300 to DN450 pipes, E14-085-6 for DN375 to DN600 pipes, E20-085-6 for DN600 to DN900 pipes.

Wastewater and sewer pipeline networks are under stress, and as time goes by, underground pipeline networks continue to age and breakdown. Aussie Trenchless believes repairs using traditional civil open cut methods are far too costly and disruptive on communities.

Meredith says trenchless rehabilitation techniques continue to grow in volume as

they are a cost-effective repair solution.

“The SRP EXP Spiral Lining System can be installed under flow conditions. With no by-pass pumping needed, it is quick and efficient using a third-generation, high quality profile to ensure ease of installation, providing a value-added outcome for the network owners,” he says.

The SRP EXP Winding Unit and Cages are a standard design. Each winding unit supplied is the same, the cages vary in diameter to suit the underground pipe size and all parts that make up the cages are standard and interchangeable on some cage sizes.

The special winding machine is positioned into an access chamber or pit, then helically winds the SRP-EXP ribbed strip to produce a pipe within the existing pipeline. Aussie Trenchless’ SRP-EXP is first installed at a smaller diameter, then expanded to closely fit against the internal surface of an existing pipe.

During this initial wind-in process the spiral pipe lock holds the spiral wound pipe tight to the initial and smaller diameter.

Once the far end of the installation length is reached, the SRP-EXP Liner end is then restrained, with the lock area sequentially released such that the SRP-EXP pipe expands in a controlled manner until it has been

n August 2022, a 10-person team installed what could be one of the largest ultraviolet liners ever installed in the United Kingdom. iMPREG states that it was one of the largest UC cured in place pipe (CIPP) liners installed by project partner Lanes Group.

The 42 m long and 1800 mm diameter liner took the effort of a full team and infrastructural planning prior to the installation. iMPREG’s UK Technical Manager, Jack Talbott, says that this is one of the largest diameter UV liners the company has supplied to a UK contractor.

“The project demonstrates an expansion of what can be achieved by UV CIPP by matching advances in manufacturing and UV lining systems with the installation expertise of Lanes as a contractor,” he says.

and diameter of 1800 mm. The thickness of the liner for this project was approximately 15.5 mm. Additionally, the liner was supercharged with UV light train with three mega light cores with three 2000-watt bulbs each - the combined power output could come to 36,000 watts.

The liner was pulled through the storm drain on the project via a 10-tonne winch.

Curing time on the project was approximately 70 minutes, with the curing speed having been set between 500 mm and 700 mm per minute.

Overall, the operation took around 18 hours to complete.

The GL16 liner made it easy for the team to plan and disregard a worrying weather forecast thanks to its lack of temperature sensitivity. Two 3 m diameter concrete chambers beneath the road were exposed, so the liner could easily be installed between.

However, the true success around this project was a successful collaboration between the teams of iMPREG, Lanes Group, Urban & Civic, and ProKASRO. What first seemed like an overwhelming task was successfully achieved in one day.

The whole iMPREG team is proud to work with such highly skilled partners around the world to complete projects of any scale.

Gary Carey, Lanes Group’s Lining Supervisor, says that though the project was challenging, it was able to succeed thanks to those involved pulling together as a team.

“The Lanes sewer rehabilitation division’s partnership with iMPREG and ProKASRO worked extremely well,” he says.

PEOPLE ON THE MOVE

People on the Move In this new and regular column, Trenchless Australasia is tracking new appointments in Australia and New Zealand’s trenchless industries, celebrating the people who make the industry what it is.

Phil Micallef – Business Development Manager, kwik-ZIP

Michael Hodnett – Business Development Manager, PSSS

Jason Climo – Head of Horizontal Infrastructure NZ, Veolia

kwik-ZIP has announced Phil Micallef has joined the team as a Business Development Manager.

Micallef brings with him 14 years of experience and skills in geosynthetics in the construction and civil sectors, befitting his ability to succeed in his new role at the company.

“During my time in the civil industry, I noticed that the trenchless sector was rapidly evolving which sparked my interest and am excited to have a chance be a part of this growing sector,” says Micallef.

His role with kwik-ZIP will involve providing full cycle business development activities. This includes market research, strategic market development and building deep customer relationships within the industry. Micallef is looking forward to becoming a trusted advisor for kwik-ZIP customers by continuing to develop solutions and creating strong customer relationships within the trenchless and civil industry.

Michael Hodnett has joined the PSSS team as the Business Development Manager (BDM) for Western Australia.

He brings with him a strong history of providing effective solutions to clients and found himself drawn to the PSSS philosophy – “Yes we can.”

“Being based in WA and being able to service the entire state, provides me with a pretty large canvas to work with,” says Hodnett.

“While PSSS has been servicing clients in WA for many years, there hasn’t been the focus of WA based BDM for an extended period of time,” he says.

He says that the main focus of his new role will be to extend PSSS ability to service its existing WA clients, and extending those services to new clients who can benefit from the company’s store of critical stock. Hodnett is working to build up PSSS’s supplies further in its Jandakot-based WA warehouse.

“This will expedite our local WA customer orders, and reduce lead times and freight costs,” says Hodnett.

Veolia’s Jason Climo is moving into his new role as Head of Horizontal Infrastructure New Zealand.

Climo is one of Veolia’s nearly 200,000 employees across five continents.

He brings with him over 25 years of experience in the water industry, from water and wastewater treatment to the construction of facilities, pumping stations and pipelines. His directional drilling experience includes projects that have involved pipe bursting, pipe ramming and fold & form lining, spiral lining and junction seals.

“It’s my passion to see Veolia cement its position as the leader in pipeline renovation across Australia and New Zealand,” says Climo. “I’m particularly looking forward to bringing new and existing innovative technologies to our clients across NZ and further building our great team to continue delivering the best value.”

Climo will provide greater consistency in Veolia’s NZ approach to delivering creative, innovative and where possible trenchless technologies.
