As the voice of the trenchless industry, it’s imperative that we address the pressing issue of emissions reduction. Our industry plays a crucial role in modern infrastructure development, rehabilitation of ageing assets and upgrading projects with trenchless technology.

Over the years, the trenchless industry has made significant strides in innovation and efficiency. This can be seen through utilities using more trenchless methods to complete its operations.

Recently, SA Water trialled a trenchless fix for the first time in its metropolitan sewer network to avoid unnecessary disruption to businesses and the community.

SA Water Senior Manager of Infrastructure Planning and Strategy Daniel Hoefel said South Australia needs to keep challenging itself to explore different ways of maintaining assets to ensure it is minimising any impact on the surrounding community from its work.

If SA Water had used traditional repair methods it would have involved removing pavers in Rundle Mall and excavating down to get access to the pipe, causing disruption to the community and local traders, along with impacting the area’s amenity.

However, but using this trenchless method, the utility only needed to access one of its nearby sewer chambers for repairs, and after one of the team was safely lowered inside the chamber, SA Water used a combination of ropes and steel rods –guided by a CCTV camera – to push the sleeve to the impacted section of pipe.

Similarly, Rob Carr has addressed how it is working towards sustainable solutions to decrease its ecological footprint.

Rob Carr is committed to limiting its environmental impact and reducing its carbon dioxide emissions by 40

per cent by 2030, an ambitious target.

From utilising recycled materials to incorporating renewable energy sources like solar panels, among others, these practices are significantly lowering carbon emissions associated with Rob Carr’s construction projects.

Most construction companies, like Rob Carr, need cement, concrete, steel, and fuel to carry out its projects.

However, these resources generate significant carbon dioxide emissions which impact operations and, ultimately, the environment.

To address this challenge, we are seeing more and more companies in the industry allocate resources towards developing cleaner and more energy-efficient technologies, provide comprehensive training programs for industry professionals to promote best practices for emissions reduction, and foster partnerships with environmental organisations, government agencies, and other stakeholders to advocate for policies that support emissions reduction in the industry.

There has also been an increase in establishing transparent monitoring systems to track progress towards emissions reduction goals.

By taking proactive steps to reduce emissions, the industry is not only safeguarding the environment for future generations but also positioning trenchless technology as a driving force for future project works.

As an industry that is already adaptable and willing to embrace emerging technologies, it is exciting to see what other sustainable solutions are on the horizon.

Happy reading!

President’s message

Welcome to the latest edition of Trenchless Australasia. This edition explores trenchless’ role in the energy transition, and how the industry’s technology is helping reduce emissions from pipeline construction, rehabilitation, inspection, and maintenance.

The issue contains content focusing on environmental benefits of no-dig methods, as well as the new technology which is already part of the energy transition. It is a time in the industry where utilities and projects can really benefit from trenchless technology as it is already a low impact on the environment form of work.

In an exciting development, the Australasian Society for Trenchless Technology (ASTT) has announced the members of the inaugural Young Trenchless Professionals (YTP) Committee.

With Victorian Councillor Ash Hamer leading the committee, the ASTT hopes to achieve its mission and strategic objective through improving member awareness and engagement, organising trenchless forums, and providing input to council on industry trends and changes.

The annual general meeting (AGM) is just around the corner, and we invite everyone to join us at Prime Creative

Media’s Mornington Boardroom on Tuesday April 30, 2024.

The AGM will commence at 10am and will feature reports myself and Secretary Trevor Gosatti. The meeting will also discuss the 2024 council structure, the role of special interest groups and the strategic plan.

As part of the changes to the 2024 council structure, we have welcomed Andrea Edney and Amy Farrugia to the board.

A relatively new approach from the council, this move means the new members will help promote specific areas such as training, standards, and education, rather than representing a particular state or territory within Australia.

I express a big welcome to both Andrea and Amy and look forward to working with you both on this new venture.

It is hard to believe we are already in April. Before we know it, it will be 2025 and No-Dig Down Under will be back on everyone’s calendars. This is your reminder to book your booth for the event which will be taking place in Melbourne.

• increased engagement from young professionals to support development and growth of the society

• added support to council to achieve strategic objectives

• development of the next generation of ASTT leaders

• mentoring and coaching of young professionals.

The ASTT Council strongly supports this group. It is planned to hold a forum and a function for the YTP around the timing of the ASTT AGM and the OzWater conference.

No-Dig Down Under 2025 & 2026

As touched upon in the last issue of Trenchless Australasia, the ASTT Council will continue to work together with our media partners, Prime Creative Media, to bring more high-quality events for 2025 in Melbourne and then the ASTT

hosted ISTT International No-Dig to be held in Auckland, New Zealand in September 2026.

If you haven’t already, put these events in your planning calendar to be a participant as both events will provide great value for your businesses and the trenchless technology industry in our region.

ISTT administrative changes

After the recent resignation of the ISTT Executive Director Peter Smeallie, I was honoured to be appointed to the Executive Director position effective from March 1 2024 on a part time basis.

In coming into the role, I acknowledge the excellent contribution of the outgoing ED in Peter Smeallie and thank him for his service to the organisation over a seven-year period including a difficult time during the pandemic. On behalf of the ISTT I thank him for his service.

By accepting the position as Executive Director, I join the full time ISTT Program Director, Kyoko Kondo in the administration of the ISTT for the foreseeable future.

The new part time role is not expected to affect my current position as the Secretary and Treasurer of the ASTT. In fact, there are many synergies between the roles that may complement both organisations going forward.

Tunnel boring to begin on North East Link

The North East Link in Victoria is making progress, with segments of the first tunnel boring machine (TBM) to dig the twin tunnels lowered into the ground.

At the Watsonia site for the North East Link, two of the largest TBMs in the southern hemisphere will start digging the 6.5km tunnels in mid 2024.

The first pieces of the machines were lowered into the ground by a 550-tonne gantry crane. When assembled, each 4000 tonne TBM will be 90m long and more than 15m wide.

The TBMs will soon work their way south from Watsonia toward Bulleen, while crews begin installing tunnel walls made of almost 44,000 individual concrete segments.

Across the north-east, a significant level of work is underway to prepare for tunnelling. A 200-metre-long TBM launch box in Watsonia has been completed, and work has started on the underground box structures near Lower Plenty Road and Manningham Road where the TBMs will excavate into on their journey south.

Melbourne Water to commence relining works

Melbourne Water is set to commence relining works on the North Yarra Main Sewer, a sewer that transports sewage from Melbourne’s north-east to the Western Treatment Plant.

The works are scheduled to start on Wednesday 3 April and are expected to take five to six weeks to complete. Works will be completed as part of night works between 7pm to 6am, Sunday to Thursday.

Melbourne Water will use relining as it will allow the utility to reline the inside of the existing sewer with new plastic sleeving, ensure that disruptions are kept to a minimum, allow upgrade works to be completed more quickly and efficiently and ensure the structural integrity of the sewer is maintained for decades to come.

The North Yarra Main Sewer was first constructed in the early 1900s with some sections now coming to the end of their working life.

In October 2023, Melbourne Water began major construction works to rehabilitate the upper section of the sewer.

The lower section of the North Yarra Main Sewer from Yarra Flats Park, Ivanhoe East to Farm Rd, Alphington will be relined as part of a later project, which is planned for 2024 or 2025.

Rob Carr celebrates safety excellence

The Rob Carr Monthly Safety Awards celebrated the company’s representation of its commitment to workplace safety.

There were 392 submissions on the Rob Carr’s platform last year, with 73 individual contributions for best practice alone.

The company’s workforce continued to address potential unsafe situations, which built upon the positive reporting culture embedded within the company.

There were also a further 111 improvement suggestions, showcasing the workforce’s efforts in shaping a safer work environment.

The awards honoured outstanding workers for their proactive approach and dedication to safety with 26 award winners across various categories throughout the year.

The company celebrated this achievement with a statement on LinkedIn.

“But beyond the numbers, the core of our approach is developing a strong culture of transparency and reporting,” the company said.

TRACTO delivers first GRUNDODRILL ACS300 in Australia

TRACTO Australia has delivered the first Australian GRUNDODRILL ACS300 to one of its longstanding partners, R&R McClure in Victoria.

Based in Castlemaine, Bendigo and Mildura, VIC, R&R McClure specialises in the installation of underground power, water and

communication for utilities, government and private businesses.

Looking to expand their horizontal directional drilling capabilities, especially in harder ground conditions, the company looked to its longstanding partner in TRACTO Australia. “Always at the forefront when applying

the latest trenchless technologies, the ACS300 will ensure that they can continue to increase capacity in rock drilling and digital technology,” the company said.

“Thanks again to Tim McClure and Kelly McClure for your continued support and we wish you all the best your new machine.”

Sliplining on display in Parkville

Greater Western Water (GWW) has upgraded a 134-year-old water main in Parkville, VIC through the use of sliplining.

GWW began the Royal Parade Upgrade project in May 2023 in partnership with Fulton Hogan, which involved replacing the existing water main with two kilometres of new pipeline.

Construction utilised sliplining technology to insert a new 560mm diameter inside the existing 750mm diameter wrought iron main. Sliplining was used as it helped limit disruption to local businesses, limit water supply interruptions and pressure and ensure construction was safer and more time efficient.

GWW Acting General Manager Growth and Infrastructure Bri George said the upgrade was a high priority due to the water main’s condition.

“The Royal Parade water main is a critical asset and has been providing the Parkville community with reliable water services since 1889, that’s more than 130 years of ongoing use,” she said.

This upgrade was crucial to ensure reliable water services for decades to come.

The GRUNDODRILL ACS300 is capable of drilling in all geologies.

Transforming South Australia with trenchless

SA Water has taken trenchless technology across South Australia in rehabilitation, maintenance and installation projects.

SA Water replaces under-track pipes in Mount Barker

SA Water used horizontal directional drilling (HDD) to replace 55m of water mains in Mount Barker.

e utility company chose HDD to minimise the environmental and community impacts of the work and drilled at a depth of 2.4m underneath Mount Barker’s heritage SteamRanger tracks.

e section of pipe is critical to the water service in Mt Barker and surrounds.

SA Water General Manager of Sustainable Infrastructure Amanda Lewry said that HDD is considered to be safer and more e cient for the project.

“ ese works are part of our e orts to continually improve water services for our customers, with this section of pipe critical to transporting water to residents and businesses in and around Mount Barker,” she said.

HDD to help Monarto pipeline project

SA Water used HDD to assist in installing a section of pipe underneath the Melbourne to Adelaide rail corridor.

“Our crews have been operating a horizontal directional drill to bore a 60-metre-long tunnel under the track for the pipe to be pulled through via a trench on the other side at the fringes of Monarto Safari Park, where they’re currently wrapping up the nal section within the park,” SA Water Senior Manager of Capital Delivery Peter Seltsikas said at the time.

“Rather than lay PVC pipes like we’re using elsewhere for the project, we’re using highdensity poly pipes, due to their increased exibility to withstand ground movement and their ability to be welded together and pulled through the tunnel.”

CCTV use in Adelaide

SA Water employed CCTV cameras for two rail sewer chambers, as part of its rehabilitation program.

e two chambers located under the Keswick

Bridge carries tra c on Anzac Highway over rail tracks and provides access to a sewer main that transfers sewerage to the Bolivar Wastewater Treatment plant.

SA Water Senior Manager and Infrastructure Planning and Strategy Dr Daniel Hoefel said $1 million will be invested to rehabilitate around 40 concrete sewer chambers across the state.

“ is type of work is vital to sustaining the structural integrity of these assets and involves using CCTV cameras to inspect the condition of the chambers – allowing the entire structure to be assessed in detail to prioritise those that require refurbishment, with these two in the rail corridor identi ed as a priority,” Hoefel said.

“Working across the weekend during the temporary line closure, our contract partner, Inter ow, cleaned inside the chambers beneath the Keswick Bridge with a high-pressure hose to remove any debris or fat from the walls, before applying a protective coating to the concrete.”

SA Water completes extensive sewer scrub

Over a six-month period, SA Water cleaned and inspected more than 130km of sewer pipes across Australia.

Hoefel said the program plays an important role within the sewer network.

“Typically, the foothills experience more blockages due to the presence of thirsty tree roots, which break into sewer pipes looking for water and continue to grow, blocking the ow of sewage,” Hoefel said.

“In Adelaide’s west, the soil composition is rather loose and sandy which makes it easier for this material to nd its way into our pipes and build up over time.

“To put this into perspective, we recently removed more than 110 tonnes of silt from a 1900–metre-long section of one of our large sewer mains in Birkenhead.”

To cut through blockages, the SA Water team used a vacuum truck equipped with a jet rodder, to work their way through the pipe and remove any unwanted material.

“Given sewage is actually 99.9 per cent water, all of the water we remove from the sewer

network is recycled and supplies the jet rodder, as the truck is designed to separate liquids and solid matter,” Hoefel said.

Trenchless to form desalination plant SA Water will use trenchless technology to implement design changes for its proposed Billy Lights Point desalination plant.

e small-scale plant will provide longterm water security for the people of the Eyre Peninsula and ensure the health of the Uley South Basin.

e design changes include a trenchless construction method for the installation of the plant’s intake and outfall pipes, and the placement of the pipes o the coast of Billy Lights Point.

“We will need to conduct additional geotechnical studies to re ne the scope of the trenchless construction method, and from early next month, we will use a barge and small drill rig o the coast of our existing nearby wastewater treatment plant to collect soil and rock samples from the ocean oor,” Seltsikas said.

“ is will enable a better understanding the site’s geology, to determine the exact type of construction method, which could include directional drilling or tunnelling.”

e geotechnical work is expected to take several weeks, and the results will inform a detailed concept design.

“ e Uley South Basin is the primary source of drinking water for Port Lincoln and the lower Eyre Peninsula, but the Basin is under stress, so a desalination plant is essential to augment supply,” Seltsikas said.

“A combination of long-term lower groundwater recharging of the Basin and ongoing extraction rates to meet community demand mean the aquifer’s water levels are likely to reach historically low levels by the mid-2020s.

“We need to build the desalination plant at Billy Lights Point to protect the health of the Basin and provide an alternative climateindependent water source to deliver drinking water to the local community.”

From Mt Barker to Adelaide, SA Water took trenchless technology across the state.

Driving towards sustainability

A wave of innovation is changing the scene, with Rob Carr actively working towards sustainable solutions to decrease its ecological footprint.

In a time when environmental concerns are the focus of discussions, industries are being pushed to change their practices and limit their impact on the planet.

Construction and engineering companies have shifted their priorities beyond just pro t.

Today, many prominent companies acknowledge that sustainability is not solely a moral duty, but also a key business strategy.

One example is Rob Carr, which is not only reducing its ecological impact but also gaining a competitive edge by integrating sustainable practices into its operations.

“As part of the Soletanche Bachy group, the world leader in foundations and soil technologies, Rob Carr has implemented the “Green is Great” awareness initiative to encourage sta to do their part in joining

the company’s e orts in reducing its carbon dioxide emissions,” Rob Carr General Manager Angelo Soumboulidis said.

Within the group’s strong environmental approach, Rob Carr is committed to limiting its environmental impact and reducing its carbon dioxide emissions by 40 per cent by 2030, an ambitious target.

From utilising recycled materials to incorporating renewable energy sources like solar panels, among others, these practices are signi cantly lowering carbon emissions associated with Rob Carr’s construction projects.

Like most construction companies, Rob Carr needs cement, concrete, steel, and fuel to carry out its projects. ese resources generate signi cant carbon dioxide emissions

which impact operations and, ultimately, the environment.

Reducing carbon emissions is a focal point for Rob Carr in its commitment to achieving long term sustainable operations by employing a mix of strategies and in its e orts for reasoned and sustainable growth, the company is relying on a pragmatic environmental action plan focussing on key areas.

Three key areas:

• Energy – reducing carbon footprint by 40 per cent by 2030 by reducing fuel and electricity consumption

• Cement – reduce indirect carbon dioxide emission by 20 per cent by 2030 through reducing cement consumption using less concrete, using alternative binders

and bespoke cements with lower carbon footprints

• Waste – minimising the generation of onsite waste and maximising recycling and recovery of materials by using specialised vendors who reuse construction waste and materials to generate new reusable products.

To ensure sustainable operations, Rob Carr has implemented a stringent emissions tracking framework for its projects and the business as a whole.

e framework, developed in-house, includes the detailed calculation of carbon emissions for any o ering made to a client at tender stage.

Ultimately, this development has enabled the company to compare the carbon dioxide impact of a basic solution with that of a variant during the tendering phase, in order to promote, wherever possible, the solution that has the least impact on the environment.

e framework is in template form and incorporates detailed calculations within Rob Carr’s estimating software, ensuring that the requisite detail and accuracy of information are available for any developed project solution.

If successful, the Rob Carr project team receives this information and progressively tracks the project’s carbon dioxide emissions

throughout its lifecycle.

“ e aim for the project team is to innovate and implement new processes or solutions or supply alternative materials, which will help to further lessen the projects’ overall carbon dioxide emissions and ultimately the company’s overall ecological footprint,” Soumboulidis said.

e project reporting merges and tracks several environmental indicators against a B0 scenario, such as total fuel consumption, electricity, gas, water, concrete, steel, and other materials in a monthly report, thus allowing for continual improvement.

Integrating renewable energy systems into construction projects is becoming increasingly prevalent.

From incorporating solar panels into its site facilities to lessen the need for power generation using fuel, through to looking into machine electri cation using electric power packs to reduce energy consumption, Rob Carr is at the forefront of o setting carbon emissions in the trenchless space contributing substantially to the sustainability of the built environment.

Further breakthroughs in materials science are driving the creation of environmentally friendly substitutes for standard construction

materials, further decreasing the ecological footprint of the business.

rough the group, Rob Carr has access to EXEGY, a low carbon concrete alternative made exclusively by Soletanche Bachy.

“EXEGY is a package of materials and group services which provide group companies such as Rob Carr and ultimately clients, the most suitable low-carbon footprint concrete or grout for any project,” Soumboulidis said.

Ultimately, the sustainability of any construction project relies on collaboration within the supply chain. By collaborating closely with the group, other group companies, suppliers and subcontractors, Rob Carr enforces strict environmental standards and encourages the adoption of sustainable materials and practices in its operations.

With climate change becoming a rm reality, construction and engineering companies will play a bigger role in fostering sustainability.

By embracing innovation, and prioritising carbon dioxide reduction strategies, Rob Carr will not only minimise its environmental impact but also drive positive change across the trenchless industry.

Sustainable outcomes through collaboration

Partnering with some of the world’s leading suppliers of trenchless technology solutions, Pipe Core is collaborating to support sustainable outcomes across the Australian and New Zealand industries.

In an industry inherently driven to minimise environmental impact, Pipe Core is leading the way with innovative trenchless pipe rehabilitation technology. is mission is supported by the company’s international suppliers who are independently taking further steps to adopt sustainable practices.

Pipe Core has one of Australia and New Zealand’s most comprehensive list of supply partnerships, including some of the world’s leading suppliers of trenchless technology. is includes machinery and equipment covering the entire project delivery ecosystem from inspection, cleaning, repairing, maintenance, and renewal of utility and councilowned underground infrastructure.

Pipe Core’s suppliers align with key sustainability themes, such as elimination of single-use plastics, energy consumption,

carbon reduction and social impact, contributing signi cantly to environmental and social responsibility.

Reducing packaging waste

One supplier that has made meaningful adjustments to its packaging with the reduction of plastic is Renssi.

“ is move represents a crucial stride towards a more sustainable and environmentally conscious future,” Renssi Chief Executive O cer Jouni Savonen said.

While others are focusing resources to further improve and revolutionise their environmentally responsible practices.

Lowering carbon emissions

As part of the Trelleborg Group, the Trelleborg Seals & Pro les division, which creates cured-

in-pipe place (CIPP) materials and trenchless equipment, works toward the same set of sustainability goals.

e Group climate target is to halve direct and indirect CO2 emissions (Scope 1 and Scope 2) by the end of 2030 compared with the base year 2021, and, during the same period, reduce emissions along the value chain (Scope 3) by 25 per cent.

“Trelleborg is currently investigating ways to increase the share of recycled or bio-based raw material in the product portfolio and reduce the amount of CO2 released during the whole manufacturing process,” Trelleborg Product Manager Consumables Matthias Peppel said.

Reducing the job site squeeze

In utility installations, there is no one-size-fits-all job and as such there needs to be a variety of equipment available for contractors to utilise. Companies that offer a range of equipment that effectively service a variety of job sites can help boost a contractor’s abilities, accessibility, and sustainability.

Utility installation projects often mean large, sprawling job sites, encompassing vast areas, and requiring large-scale equipment, but there are instances when work will need to take place in tighter, more con ned spaces.

Fitting the bulky equipment necessary for utility installations into such compact areas could require land clearing and additional works to remove obstructions. is unnecessary excavation and clearing can result in lengthy project delays and can also tarnish a job’s sustainability credentials.

Boosting sustainability credentials

Environmental, social and governance is increasingly becoming a key focus for contractors and there are a range of ways that workers can bring more sustainable practices to utility installation job sites.

Sustainable practices on utility installation jobs can take on a variety of forms including reusing and recycling materials onsite and minimising environmental disturbance. In restricted and compact job sites it can also mean employing smaller, compact equipment to help get the job done in favour of excavating to give site access to large equipment.

e restrictions that these compact sites impose on equipment can mean the di erence between accepting a job or rejecting it. Understanding the varying job sites means o ering a complete range of equipment, including machinery that can be used in compact, con ned job sites.

Making the inaccessible accessible Vermeer’s Pedestrian Trenchers are the perfect solution for small-diameter utility installation, particularly when job site access is restricted.

e slender pro les of Vermeer’s Pedestrian Trencher units mean they can comfortably access tight spaces, including passing through standard backyard gates.

e strength of Vermeer Pedestrian Trenchers does not come at the expense of their smaller size, with the three units in the range o ering high torque digging and delivering optimal power to job sites.

Di cult terrain on job sites is no hurdle for Vermeer’s Pedestrian Trenchers, with highmount track design o ering excellent traction and minimising ground disturbance. Further underscoring the adaptability of the range, the machines give operators the option to use tracks or tyres – allowing workers to unlock maximum productivity and performance in spite of varying

Manufacturing Quality PE100 Pipes

Since 2004, Australian Custom Pipes (ACP) has been providing conventional piping systems, custom pipes, injection moulding and fabrication to the Gas, Water, Fire, Electrical and Communications pipeline construction industries

If it’s quality products and service you’re after give ACP the opportunity to impress.

A master in customised pipes

Australian Custom Pipes no longer needs an introduction. The independent, Australian-owned polyethylene pipe manufacturer has been making waves for more than 20 years.

The company’s quality polyethylene (PE) pipes have supported countless projects around the country and have continually proven to be compatible with trenchless methods of construction.

Australian Custom Pipes (ACP) is committed to providing high-quality PE pipe, complemented by dedicated customer service and support.

e company can provide bore pipe in white or orange, in large coils and in lengths up to 20m, or customised to suit any project, helping clients save money by getting more pipes laid each day and minimising waste from o cuts.

In addition to a reliable product, ACP always delivers as promised.

e company knows how important it is for deliveries to be on time, as nobody wants to keep their crew on standby waiting around for a truck to arrive.

ACP keeps its delivery date promises and works closely with clients to coordinate the best outcomes.

A natural trenchless fit

With the rapid take up of solar as the most cost-e ective build and generation of power, ACP have been involved in the supply of conduit to major projects in regional Victoria, western New South Wales and southeast Queensland.

During this initial avalanche of solar installations, a major challenge arose in running conduits, as power was coming in from all directions from numerous arrays of panels over a widely spread area.

To overcome these issues, the speci cation moved to trenchless technology, speci cally horizontal directional drilling (HDD), to

allow conduits to come in and transverse many obstacles on their way to sub stations.

ACP was able to provide a 315mm PE orange conduit in place, capable of handling the heavy-duty cables involved, meeting the UV stability required and with little disruption to the major works underway.

ACP has developed all its PE pipes to

meet AS2053 for conduit applications.

is allows client project works to move away from the older methods (gluing PVC/ welding steel pipes) and towards the use of HDPE coils using trenchless options like HDD or pipe bursting.

is has been of great bene t when clients are looking to install pipes over great distances and has been particularly bene cial and e ective on major projects like airports, subdivisions, highway construction, infrastructure builds involving water, sewer, power, communications, re, gas, river crossings and more.

Ticking all the boxes

ACP is recognised in the market for costcompetitive quality products and service. e company is dedicated to employing ever-increasing modern machinery and rigid inspections procedures throughout its manufacturing processes to ensure a high standard of accuracy with pipes, ttings, and fabrications.

ACP also prides itself on its quick turnaround times, both in customer service and manufacturing, and its products are approved to supply water authorities from Adelaide to Southeast Queensland.

ese pipes support projects in regional and remote areas, with PE pipes up to 315mm in the colour, stripe, jacket, or even internal jacket to meet all speci cations.

Even if the required pipe is uncommon or not in stock, ACP is capable of manufacturing and delivering the necessary products in a short timeframe.

Redefining relining in Wodonga

In a step towards enhancing stormwater infrastructure, M. Tucker & Sons recently completed a challenging relining project for the Wodonga City Council.

The relining project, commissioned by the Wodonga City Council in Victoria, aimed to rehabilitate an ageing stormwater line.

e asset in question was deteriorating, and compromised by signi gant tree roots to such a state that all previous e orts by other parties had failed to address the issue.

As such presenting potential risks to public health and the environment,

M. Tucker & Sons’ experience and enginuity was crucial in ensuring the seamless execution of the project.

Speci cally, the company mobilised a Melbourne based team to remove the roots and other hard intusions, followed by the installation of 98l/m of IMPREG DN225 GRP liner, to structurally rehabilitate the asset and guarantee its service life, free from roots and further damages for the next 100 years.

is undertaking not only showcased the company’s expertise, but also highlighted its commitment to delivering solutions in demanding environments.

“In addition to 4000psi water cutting robotic works to remove the root knuckles at joints, some larger displacements were also robotically re-shaped to ensure minimum disruption to the hydraulic performance of the line as these joint joints were unable to be dug up and re-aligned,” M. Tucker & Sons Trenchless Supervisor Matt Kershaw said.

Within the fully deteriorated asset, navigating the complex nature of the large displacements and intrusions, the job required meticulous planning and execution to ensure the relining process was carried out e ectively.

Despite the complexity of the challenges, the company showcased its suite of services tailored to suit the clients budget and scenario, resulting in a plan of action that was de nitive and cost e ective, with no open cut works to reinstate.

“ e asset was prepared in the days prior to installation which included CCTV, drain cleaning, robotic concrete grinding works

and high pressure water cutting to ensure the smoothest possible process during installation,” Kershaw said.

“ e liner was installed and 11 property connections reinstated, returning the drain to a structurally sound state and extending its serviceable design life for another 100 years” e large taproots were the most challenging aspect, according to Kershaw, as they exceeded the limitations for plain root cutting or any basic cleaning nozzles.

“Using our high prtessure water cutting technology on the cutter system, allowed us to position a robotic crawler at the defect and cut very presisely with a high-pressure water nozzle,” Kershaw said.

“By utlitising this methodology you can target the areas you need to address and monitor progress in realtime on the screen in the van.”

Despite encountering unforeseen obstacles, M. Tucker & Sons’ team remained agile to keep the project on track.

is included e ective communication and collaboration with the Wodonga City Council, which played a crucial role, according to Kershaw.

“ e initial site appraisal meeting and communication throughout the whole project was key, including CCTV inspections

in the site appraisal,” Kershaw said.

“ is allows our teams to gain clarity on the requirement of the project and we are able to in turn pass that clarity on to the client when discussing the project and setting timeline expectations.

“It is crucial to keep the client informed as works progresses, not only so as they can address stakeholder enquiries, and track progress against construction programs, but it also gave the council the con dence that we could and would deliver what we promised.”

Now, the rehabilitated stormwater line is poised to serve the community reliably for years to come, ensuring the continued sustainability of Wodonga’s infrastructure. is successful relining project is a testament to M. Tucker & Sons’ commitment to excellence and innovation in the eld of civil and trenchless solutions and the industry as a whole.

rough delivering the project, the company has not only strengthened stormwater infrastructure, but also contributed to the sustainability of the community it serves.

Delivering streams of innovation with Interflow

Mostly unseen, culverts allow waterways to flow while acting as a bridge in supporting roads and rail networks. These culverts are now ripe for attention as increasing adverse weather events, along with ageing structures, highlight the essential role they play in regional and metro infrastructure.

Recently a major Australian international airport conducted a regular condition assessment of its stormwater assets and found that one of the stormwater pipes running under a taxiway showed some emerging defects.

Inter ow Business Development Manager Stephen McGowan said the taxiway was closed as any potential risk of it collapsing as an aircraft travelled overhead was unacceptable.

“Closing down any critical infrastructure at a major airport has a very high daily cost, and they asked if we could provide a solution, and how quickly could we mobilise,” he said.

“We came up with a solution, veri ed by our in-house chartered engineers, and had the works completed just weeks after they rst approached us.”

Inter ow delivered the site works over three days and was awarded the contract on the basis of its competence and their trust in the company’s ability to meet the client’s high standards.

is case study is valuable in demonstrating two important points, one is that culverts can be found in many situations that are vital to the performance and safety of the land and infrastructure around them.

e other is that there are highly e ective maintenance and renewal solutions available to asset owners with outcomes that don’t involve the digging of trenches, the closure of roads or runways or requirements of costly and timeconsuming stakeholder issues.

Why choose culverts now

Once culverts are installed, they don’t receive a great deal of attention.

McGowan said that has been because of the cost to the organisation responsible for their management and that they don’t attract a revenue stream, unlike wastewater and potable water.

Another is because it was assumed these assets would have a 100-year service life, which McGowan said “is proving wildly incorrect in most cases”.

As a result of factors including increased tra c loads, more frequent major weather events, and assumptions around materials and coatings,

many culverts are showing signs of failure in less than half that time.

Some materials in place, such as zinc coated corrugated metal pipes, are deteriorating much earlier that assumed.

For many culvert asset owners in local council, rail, and arterial roads, that’s right about now.

“ ere’s research initiated by V-Line’s Principal Structures Engineer, Ali Chaboki, that presents ndings regarding the remaining life in buried corrugated steel culverts at particular service life stages,” McGowan said.

“ at research is vital to V-Line, which relies on 5000 culverts and 1200 bridges on the Victorian regional rail network, but information contained in the report can also be extrapolated out to other culvert applications.”

Data from this research and other similar studies can be used by infrastructure managers to re-assess the performance life of their own culverts.

Inter ow culvert experts regularly discuss such insights with infrastructure managers and can devise trenchless solutions for culverts that are reaching or have gone beyond their end of functional life.

Remote-controlled culvert renewal

e safety of its people is a fundamental component of how Inter ow operates. In instances where it’s di cult or dangerous for people to go in, Inter ow o ers non-personentry options.

“ at’s something unique that we o er,” McGowan said.

“It means that no one has to go into particular

culverts, and that’s a major safety improvement. When a culvert is close to collapse, that’s a far better option.”

For every customer a unique solution is designed after a deep dive into their speci c needs and the needs of their stakeholders.

“We have two of Australia’s top pipe rehabilitation thought leaders in our business, with over 65 years of experience between them,” McGowan said.

“ at’s why I mention comfort and con dence.

“Every engineer wants to know they’re making the very best choices for the future of the infrastructure they manage.”

According to McGowan, the company’s

experts leave a legacy through their work.

“At Inter ow we strive to be the very best at what we do, and in doing so we create better legacy,” he said.

Reducing disruption while shoring up infrastructure

An example of a project that involved innovation, a customised solution that required an enormous level of experience and insight, was one in Victoria, for the Department of Transport and a tier-one civil engineering contractor. e contractor was responsible for the rehabilitation of 11 bridge structures, one of them had a culvert made up of three cells using

RCP pipes that were each 1.8m in diameter. ey were a signi cant size and channelled water under a major high-tra c arterial road.

e culvert pipes, installed in 1992, had begun to fail, threatening the physical security of the road overhead.

e design of the original solution involved diverting tra c and digging up the road to lay new pipes.

Inter ow instead recommended a trenchless x, removing any need for detours and delays for road users and delivered the project in 12 days.

Improving trenchless installations with Riteline

Riteline spacers have been successfully appraised by the Water Services Association of Australia, providing a new option for pipeline installations that complies with WSA PS-324 for casing spacers.

Riteline Centralisers are an innovative solution designed to revolutionise the accuracy of trenchless installations by providing unparalleled support to the carrier pipe, ensuring its xed position relative to the bored hole or encasement pipe.

Designed for the industry

Parent company OptionX Group Chief Executive O cer Stuart Harrison said

Riteline was developed to overcome a number of limitations of traditional spacers that increased risk on pipeline projects, and he is excited that they are now o cially recognised by the industry.

“One of the limitations of traditional casing spacers was that they needed to be purchased in speci c sizes and couldn’t be adapted on-site to meet changing needs,” Harrison said.

“ is resulted in time, money and stock wastage.”

Riteline Centralisers can accommodate pipes from 100mm in diameter, with no upper limit, and can be adjusted to di erent heights, ranging from 30mm up to 125mm.

Incremental adjustments can be made to the existing centralisers rather than requiring new centralisers of a di erent size.

Typically, centralisers are made to either slot together to fully surround the pipe or

must be designed in a size that completely surrounds the pipe.

Regardless of the weight or load requirements, the maximum number of centralisers is called for.

Riteline overcomes this limitation as the centralisers can be attached to the pipe as needed, with the number of spacers required based solely on the load, providing a tailored and e cient solution.

is unique feature minimises the use of excess product and reduces costs and environmental impact.

“As each centraliser is individually attached to the pipe, the risk of catastrophic failure is reduced,” Harrison said.

“Traditional centralisers that surround the pipe can fail when they snag on an obstacle in the bore, which can cause an entire ring of centralisers to move, compromising the installation.”

Enhanced adaptability and precision

Riteline Centralisers come in both Rigid and Flex Series depending on the project requirements.

e Flex Series is distinguished by its ability to ex around bore imperfections due to its unique spring-like design that allows for tension adjustment and enables elastic deformation around obstacles to prevent

jamming and ensure a smooth work ow.

Another bene t of Riteline Centralisers is their low-pro le design, which allows grout to ow easily around them, preventing grouting failure, and ensuring secure and accurate installation all the time.

“Riteline reduces potential issues with grouting because it is tensioned on the centreline,” Harrison said.

“ is means if any air pockets do happen to form, the pipe is already tensioned in the right position.

“

ey are also designed with very high-bond adhesive strips that prevent slippage to ensure accuracy is maintained and eliminate the need for pre-wrapping or treating the pipe.”

Industry recognised, Australian owned and manufactured

Riteline Centralisers were recognised at the 2023 Australasian Society for Trenchless Technology awards as a nalist for the ‘New Technology’ category.

“Riteline Centralisers are Australian owned and manufactured, developed over the course of almost ten years,” Harrison said.

“It is fantastic to see them recognised as an innovative and game-changing product.”

Riteline Centralisers are now available on the wider market. Visit riteline.com.au for more information or to place an order.

Riteline Centralisers are individually attached to the pipe based on load requirements, so they do not need to fully surround the pipe every time.

Bothar’s cutting head innovation

The trenchless industry in Australia continues to grow and the need to provide customised solutions becomes vital for a leading subsurface contractor.

Recognising the need for advanced solutions to meet the growing demands of modern infrastructure projects, Bothar Boring has led the way in the innovation department with its vast eet of in-house designed and fabricated ‘Bothar Built’ equipment.

Now, the company is breaking new ground with its latest specialist-built cutting head.

Bothar has an exceptional team of industry leading experts and equipment manufacturing

specialists that turn ideas and concepts into cutting-edge solutions to overcome limitations of conventional methods.

In recent times, Bothar has experienced an increase in requests for installations where there is an inability to provide a retrieval shaft.

Bothar refers to this practice as ‘blind boring’ and it had been an obstacle on the company’s radar for some time.

When the company was approached for advice on providing a suitable method to install 19 x 102m canopy tubes under a live railway without the ability to use a retrieval shaft, the team was con dent they could deliver.

ere are limited trenchless methods which could deliver accuracy over such lengths.

As such, Bothar embarked on a mission to develop an innovative solution to directly install the required 500mm steel case, in rock up to 60Mpa without an exit shaft, with pinpoint accuracy, while ensuring the ground was always supported.

e result was a custom designed specialised bi-directional retractable cutting head which hadn’t been utilised on this size of installation.

Using Bothar’s in-house design and fabrication facilities, the cutting head was designed, built, and tested within a matter of weeks.

e experimental cutting head was deployed to site and proved to be extremely e ective.

e tight program constraints meant that Bothar had to install two canopy tubes at a time, adding additional complexity to the delivery.

The bidirectional retractable cutting head used to install the 500mm enveloper with absolute precision.

The cutting head on its way to a project in Melbourne.

Two laser guided vacuum units installing a 500mm diameter steel case utilising the innovation and operating simultaneously.

Bothar successfully completed the canopy tube installation and was able to accelerate the pace of the project with its bespoke cutting head.

e unique cutting head consists of three 13 ¾-inch and three 9-inch tri-cone type TCI cutters on a 50mm backing plate with water portability and outer cutters spring loaded on a 40mm greaseable solid bar hinge.

A laser guided vacuum system was used to achieve tight design tolerances at signi cant lengths.

e modi ed head was developed to ensure the tunnel is always supported by the installation of steel casing in the unlikely but possible case of ground movement.

e cutting head has since been used successfully on several projects in adverse, mixed ground conditions up to 200Mpa.

Furthermore, tackling other obstacles such as ‘blind boring’ into service manholes is now no problem with the use of this cutting head, changing the landscape of underground construction.

Bothar’s ability to utilise its vast trenchless experience to innovate such a design is backed by its inhouse workshop facility. is gives Bothar Boring an additional advantage in the ever-evolving trenchless arena for future works.

e kwik-ZIP HDXT-103 spacers were installed to facilitate the slip-lining of a mild steel cement mortar lined (MSCL) wastewater pressure main into a RC Jacking pipe, running under a rail line for the Gosnells Main Pumping Station Wastewater Pressure Main Realignment project.

Rob Carr Project Manager Marie Piette saluted kwik-ZIP’s and its innovative spacers. “ e MSCL pipes insertion is making good progress despite a challenging environment, with production e ciency notably enhanced by the simplicity of installation of the KwikZip spacers,” she said.

e simple and e cient installation process did not require any special tools or any requirement to pre-wrap the pipe.

kwik-ZIP spacers have no metal parts and are made from the company’s engineered thermoplastic blend with high exural strength, high temperature resistance, low co-e cient of friction, abrasion resistance and outstanding chemical resistance.

Integrated rubber grip pads under collars to help prevent slippage as well as kwik-ZIP’s spacers load sharing suspension system allow heavy loads to be shared across multiple runners reducing point loading and increasing the overall load capacity of the spacer.

kwik-ZIP’s series of spacers caters to a range of carrier and casing pipe size combinations. It also provides contractors and installers exibility to deal with project alterations.

In Australia, kwik-ZIP’s HDXT and HDX Series spacers have been appraised by the Water Services Association of Australia (WSAA) against the requirements of WSAA product speci cation number PS-324 (casing spacers).

e WSA PS-324 product speci cation prescribes casings spacer requirements for correct protection of carrier pipes when installed inside casings.

e spacer and centraliser manufacturer and supplier was established in 2000 following the development of the industry’s rst patented non-metallic plastic bow spring centralisers.

Since then kwik-ZIP spacers have been making waves in the industry, and the company has been producing and marketing centraliser and spacer products for wider use.

Over the years, the kwik-ZIP team has

developed and been awarded patents on various other centraliser and spacer products for applications in many industries including production drilling, trenchless pipeline installations and ground engineering just to name a few.

Today, kwik-ZIP manufactures and supplies a centraliser and spacer system for a wide range of industry sectors including production well drilling, trenchless pipeline, horizontal directional drilling, ground engineering and the general civil and construction markets.

Like all of kwik-ZIP’s products, the HDX/ HDXT spacer system series are aligned with the company’s ethos to provide simple, coste ective, and high-quality solutions.

kwik-ZIP General Manager Paul Je reys said that it was an honor for the company to be part of such major projects.

“kwik-ZIP is proud to be supplying products to such a well-respected Australian business in Rob Carr, who are considered one of the pioneers in microtunnelling in Australia and a leader in utilities infrastructure construction,” he said.

Tunnelling milestones for Sydney Metro West

Sydney Metro West has already hit multiple breakthroughs in 2024, with five stations fully tunnelled so far.

Six tunnel boring machines (TBMs) will carve out the Sydney Metro West line between the Sydney CBD and Westmead, New South Wales.

So far, four TBMs have begun their journeys commencing major tunnelling for the project.

TBMs Daphne and Beatrice were launched from e Bays Station site in Rozelle in 2023 and have tunnelled more than 4.3km towards Sydney Olympic Park.

Both TBMs achieved the rst two breakthroughs for the project. Daphne broke through rst before Beatrice, after building the section for seven months.

is led to the TBMs claiming the title as the rst in the southern hemisphere to complete a double breakthrough.

To date, the TBMS have excavated a total of 437,463 tonnes of material each and installed around 30,732 concrete segments to line the new tunnel walls.

Meanwhile, TBMs Betty and Dorothy were launched from the Clyde Stabling and Maintenance Facility site in the second half of 2023 and are also making their way towards Sydney Olympic Park.

Daphne, Beatrice, Betty, and Dorothy are expected to reach Sydney Olympic Park in 2024.

Over at e Bays Station, the site is being prepared of the project’s two remaining TBMs that will be launched towards Hunter Street.

e two TBMs will carve out the 3.5km twin tunnels from e Bays, to Hunter Street in the Sydney CBD.

Construction of the twin metro tunnels from e Bays to Sydney Olympic Park is part of the Central Tunnelling Package awarded in July 2021 to the Acciona Ferrovial joint venture.

In a move to train the next generation of tunnelling workers, the project opened a new tunnelling and infrastructure academy.

e training facility is located in Western Sydney and is managed by Sydney Metro West delivery partners Gamuda and Laing O’Rourke Consortium, who are building the tunnels from Westmead to Sydney Olympic Park.

e custom-designed facility specialises in the delivery of training in civil construction, safety, and tunnelling.

It is also designed to help upskill existing and incoming workers to the industry by building capabilities and placing them in entry-level roles on the Sydney Metro project.

Some of the training activities include

virtual reality simulators, which showcase underground tunnelling operations, and a decommissioned TBM to present a handson experience.

e training facility is accessible to workers across the industry and to members of the Western Sydney community who can access a curriculum of national accredited training forming part of the Australia Quali cations Framework.

It is expected up to 10,000 people will bene t from the training programs on o er

at the facility, with 260 people currently participating across 19 programs.

e Sydney Metro West project will double rail capacity between Parramatta and the Sydney CBD.

Stations have been con rmed at Westmead, Parramatta, Sydney Olympic Park, North Strath eld, Burwood North, Five Dock, e Bays, Pyrmont, and Hunter Street in the Sydney CBD.

e target opening date for Sydney Metro West is 2032.

Thurs 20 June, 2024

JOIN US TO CELEBRATE THE BEST OF THE BEST FROM ACROSS THE AUSTRALIAN INDUSTRIALS SECTOR

Celebrate the women who work tirelessly to advance the mining, engineering, road transport, logistics, rail, bulk handling, infrastructure and waste management industries.

Meet the newest members of the ASTT Council

Trenchless Australasia sat down with Andrea Edney and Amy Farrugia to discuss their careers and goals in joining the Australasian Society for Trenchless Technology Council.

With an aim to increase participation, the Australasian Society for Trenchless Technology (ASTT) invited Systra Bamser Associate Director Andrea Edney and Trenchless Engineering Australia Consultant Amy Farrugia to join the council.

A relatively new approach from the council, the move will bring the new members in to promote speci c areas such as training, standards, and education, rather than representing a particular state or territory within Australia.

For Edney, raising the pro le of women and opportunities for them is a goal.

“I think it’s a good opportunity to not just represent women in the industry, but also to get involved more in the industry,” Edney said.

“I’m looking forward to being more involved

in shaping the industry going forward.”

A similar sentiment shared by Farrugia, who looks forward to the knowledge sharing between members of the industry.

“I think it’s always important to be a part of the industry that you’re in,” Farrugia said.

“Not only just from a social aspect, but from sharing lessons learned, new methods, technologies, and risk management strategies.

“With the trenchless industry being relatively niche, it’s important to distribute information about trenchless methods and promote them.”

Career paths

Both Edney and Farrugia have extensive careers across the trenchless industry, both working in companies such as Spiecapag and Leighton Contractors.

Edney began her career in tunnelling through university and worked across projects such as the M5 East and Clem 7 tunnels.

Eventually, she moved into the microtunnelling space with Tunnel Corp before being contacted by a recruiter looking for a project manager to supervise a microtunnelling project.

“I met Ben Crosby in my interview, and he said he really needed someone in the trenchless division, and I left the interview with the job working in the trenchless team at Systra Bamser,” Edney said.

“I liked the opportunity that working in trenchless gave me to be a little bit more exible. at was a big plus for me.”

Farrugia, on the other hand, began her career in the pipeline industry.

“From there, I moved into some of the horizontal directional drilling projects, which I found to be very interesting,” Farrugia said.

“I enjoy the problem-solving aspect of the trenchless industry, balancing the project constraints, di erent construction methods and engineering.”

When it came to joining the ASTT Council, Farrugia said she had begun to be involved in the production of Australian standards.

“As part of that process, I will be representing ASTT as a nominating organisation within Australian Standards committees,” she said.

“For me, that speaks back to wanting to share information about the industry and helping promote it.”

For Edney, who was the inaugural

Trenchless Woman of the Year at the 2023 ASTT Awards, saw an opportunity for raising the pro le of women within the industry.

“Someone said to me, ‘We want to increase the number of women in engineering’ and I thought even if you increase the number of women in engineering, they’re still a minority in the eld.

“Whereas if you think about increasing the numbers across the board, such as women in labour, plant operation, trades, planning and supervision roles, then it makes it easier for the engineers to feel more comfortable and more con dent in their roles.”

The state of the industry

When it comes to current challenges and opportunities for the trenchless industry, both Farrugia and Edney are adamant: education is a must.

“ e trenchless technology umbrella covers a very wide range of di erent methods,” Farrugia said.

“Communicating and understanding this range of methods, the risks and opportunities, is important for industry growth.

“ e use of trenchless methods does have a lot of exibility in how you can address particular sections on a project or potentially the entire project.”

Edney agrees noting there are bene ts for both clients and the industry.

She believes that the more clients understand what the industry can do for them, then the more work the industry will have.

“But also, in terms of educating the client, understanding what the key factors are in delivering projects and getting trenchless involved can really make a signi cant di erence to like project delivery,” she said.

As education increases, so too will the use of the methods across many applications, according to Farrugia.

“As our cities and infrastructure requirements continue to grow, the underlying services are becoming more congested and easements as well as working areas are becoming more constricted,” she said, “subsequently, the number of projects involving trenchless crossings are increasing.

“In addition to method adoption across the greater pipeline industry, they are also reaching into new applications as well.”

As infrastructure continues to develop with growing populations, the trenchless industry

“Someone said to me, ‘We want to increase the number of women in engineering’ and I thought even if you increase the number of women in engineering, they’re still a minority in the field.

“Whereas if you think about increasing the numbers across the board, such as women in labour, plant operation, trades, planning and supervision roles, then it makes it easier for the engineers to feel more comfortable and more confident in their roles.”

has an opportunity to be at the forefront. Edney said most councils are looking at upgrading stormwater, sewer, and water infrastructure.

“It’s not just installing new stu , it’s rehabilitation of the older services, as well as replacement and rehabilitation,” she said.

“ ere’s just so much happening at the moment in that space, and there’s a real need for it as well.”

Trenchless Australasia publisher first to use paper-wrapping mailing machine

Prime Creative Media is Australia’s first publisher to send paper wrapped magazines at scale, in partnership with its printing and mailing supplier FSG.

Based in Bayswater, Victoria, FSG purchased the country’s rst ever paperwrapping mailing machine in January this year. Imported from UK supplier Norpak, the machine’s ability to wrap publications in paper will eliminate plastic wrapping for several Prime Creative Media titles.

“It’s the evolution of the mailing industry to abolish the use of single-use plastics in mailing

magazines,” FSG Mailing Owner and Director Michael Murphy said.

“ is follows the government’s move to get disposable plastics out of our Australian systems.”

Up until this technology was in place, the only alternative option to plastics for publishers was paper envelopes.

Murphy noted this was cost prohibitive for

many clients, because the price of producing and printing the envelopes was high, in addition to the labour of either hand inserting magazines into the envelopes or using very expensive equipment to insert into the envelopes and seal them.

is added a signi cant increase to mailing costs.

Mailing houses like FSG have experimented over the years with bioplastics, and recyclable plastics, but Murphy said the technology never quite worked out.

“We tried to use bioplastics but the settings on the machines – which use heat to seal them – make it very di cult,” he said.

“Even for those companies who worked out how to mail them, it was a challenge for consumers to separate the plastics at the end of the process or nd appropriate disposal. Eventually, we saw that the only real option was paper.”

Murphy came across this technology through his supplier UK company Norpak, who previously supplied his plastic wrapping machine.

“ ey introduced us to the idea because they saw what was happening in the European Union with the phase out of single-used plastics,” Murphy said.

“With the Australian government making similar moves towards a full phase out of single-use plastics, we think that this machine

The machine will eliminate plastic wrapping.

will be the catalyst to push the movement along in the mailing industry.”

Murphy noted that in Europe, where it was put into commercial use 18 months ago, it has already taken o .

“ e rst person to use the machine really took a leap in the dark. Now he has 13 of these machines, and those plastic wrapping machines are sitting there not being used – they are becoming museum pieces,” Murphy said.

“ at will be the future in Australia now that this machine has arrived.”

An additional environmental bene t to the machine is that because the addresses are printed directly onto the paper wrapping, it eliminates the need for ysheets – the paper that lists the addresses and is placed onto a magazine.

is improves e ciency, as it limits the printing and transportation of ysheets. It also means that only a small amount of more paper is being used in with the new system, once you take into account the paper used in ysheet printing. And of course, this opens up

a vast array of options in using recycled and sustainable paper products.

e only drawback, Murphy noted, is that the paper is less weather-proof. In Europe many people live in apartments instead of houses, and magazines are delivered in post boxes or through slits in doors.

He said it’ll be interesting to see how the paper stands up to Australia’s climate, but con dent it will work well. at being said, he noted the price of an occasional damp magazine is one worth paying to save thousands of tonnes of plastic wrapping from going to land ll every year.

Prime Creative Media COO Christine Clancy was on site at FSG in Bayswater to witness the rst publications being sent out in paper-wrapping.

“It’s such an honour to watch history in the making, to see our publications make this rst step in reducing single use plastics in our environment,” Clancy said.

She noted that the company has long been involved in supporting the growth of the waste

management industry, through its publications Inside Waste and Waste Management Review, along with its annual Waste Awards.

“After years of reporting on the challenges of single-use plastics in the waste industry, it’s so wonderful for us to play a proactive part in it by reducing our own use,” Clancy said.

“We’re fortunate to have FSG as a partner to help make this happen.”

Easy to use with your choice of user interface, the Marksman View features intuitive graphics and clear data, and with a simple single toggle control you’re more productive from day one.
