PATH TO SUSTAINABILITY GLOBALLY, A MASS DECARBONISATION is afoot across every country and every industry, as part of a broader goal to bring global energy-related carbon dioxide emissions to net zero by 2050. As companies in the roads and infrastructure industry aim for net zero targets within their own businesses, Dr Erik Denneman, Global Technical Manager at Puma Bitumen, says the journey starts by accountability. As such, Puma Bitumen recently completed a lifecycle analysis of its supply chain, taking account of greenhouse gas emissions produced at every stage of bitumen production and supply. Puma Bitumen is also offering its customers the option to offset their residual emissions using a diverse portfolio of carbon offsets offered by its parent company Trafigura. Then there is Dr. Anumitra Mirti, an environmental and climate resilience specialist and Beca’s newly appointed sustainability advisor, who argues that despite businesses increasingly selfregulating in the interest of maximising long-term value creation and protection, a whole-ofsector collaboration is required to make circular economy a reality. Meanwhile, within the asphalt world, Melbourne-based Citywide Asphalt Group has expanded its range of GreenPave sustainable asphalt products, with its products being increasingly favoured by local and regional councils in Victoria. Also, there is SAMI Bitumen, another bitumen supplier with a positive track record in offering environmentally friendly alternatives to the industry. The company also takes great care with bitumen sourcing and to minimise emissions throughout its supply chain and processing facilities. In this issue, we also look at Lintec & Linnhoff, a newcomer to Australian market but a wellestablished name in other parts of the globe. It has introduced three new asphalt mixing plants in Australia, which are designed with environmental-friendly features such as an external baghouse filter to ensure a low particulate emission rate. Across the world of construction machinery, companies like Komatsu and Dynapc are making positive strides in developing electric construction machinery. Komatsu currently has an allelectric prototype mini excavator on display at the company’s new Innovation Hub in Wacol, Brisbane; while Dynapac is expecting its CC900E electric double-drum vibratory roller to reach mass production by 2023. This edition, we also bring to you the 2022 Contractor Capability Showcase, a resource of over 250 contractors for asset managers, road owners and governments to easily find contractors for specific sectors of road construction works across Australia. The overwhelmingly positive response we received from the contractors featured in this year’s Showcase is a testament to the growth the sector has experienced over the past year since we first launched the initiative. Throughout 2022, we’ll continue to focus on sustainability and circular economy, aiming to share positive stories from the sector and guidance from experts and thought leaders to help the industry move forward.

MAJOR SYDNEY METRO TUNNELLING PACKAGE AWARDED A consortium between Gamuda Australia and Laing O’Rourke has been appointed by the New South Wales Government to deliver the $2.16 billion Western Tunnelling Package for the Sydney Metro West project. The project will deliver a new direct, 24-kilometre underground rail connection between the CBDs of Parramatta and Sydney, with stations confirmed at Westmead, Parramatta, Sydney Olympic Park, North Strathfield, Burwood North, Five Dock, The Bays, Pyrmont and Hunter Street in the Sydney CBD. The project’s tunnelling work has been structured into three packages, with the Central Package awarded to an Acciona and Ferrovial Joint Venture in July last year. The remaining two tenderers – John Holland, CPB Contractors and Ghella Australia Joint Venture and Gamuda and Laing O’Rourke Joint Venture

– were bidding for the Western Tunnelling Package. Sydney Metro has also begun the process to appoint its third major tunnelling contractor for the Eastern Tunnelling, with three consortia shortlisted earlier this year. This contract for tunnelling between The Bays and Hunter Street in the Sydney CBD is expected to be awarded by late 2022. The scope for Western Package includes

excavation and construction of nine kilometres of twin tunnels between Westmead and Sydney Olympic Park. Sydney Metro West will create more than 10,000 direct new jobs and 70,000 indirect jobs, with many of these jobs generated by this major contract. Early works will commence on the Western Tunnelling Package within weeks, with tunnelling scheduled to start late 2023. Artist’s impression of the Westmead metro station.

QUEENSLAND GOVERNMENT TO FUND FASTER RAIL PROJECT AHEAD OF OLYMPICS The Queensland Government has committed an just over $1.1 billion to deliver faster rail services between Brisbane, Logan, Beenleigh and the Gold Coast.

and Queensland governments’ previous commitment of $356 million (on a 50:50 funding arrangement) in pre-construction funding for the project. A recently completed business case puts this project at a total cost of approximately $2.6 billion. The Logan and Gold Coast faster rail will double the capacity of the Gold Coast rail line and deliver seven station upgrades

and two station relocations to improve accessibility, safety and amenity, including platform straightening, and new pedestrian bridges as part of the works. This infrastructure funding will also complement the Cross River Rail project, which will provide a greater number of public transport routes to busy venues around Brisbane. Currently, trains between Kuraby and Beenleigh share a single track in each direction, limiting the number of peak services that can run. Since March 2018, Infrastructure Australia has included ‘Gold Coast rail line and station improvements: Kuraby to Beenleigh’ in the Infrastructure Priority List and the Southeast Queensland Regional Transport Plan identifies an upgrade of the Kuraby to Beenleigh section of the rail network as a priority action.

FEDERAL GOVERNMENT ESTABLISHES NATIONAL INTERMODAL CORPORATION The Federal Government has established the National Intermodal Corporation (NIC), which has been set up to support the delivery and operation of intermodal terminals as part of the $14.5 billion Inland Rail project. It announced it would expand the Sydney-based Moorebank Intermodal Company’s mandate to turn it into the NIC and build intermodal terminals in Melbourne and Brisbane. “National Intermodal’s task is to create an interconnected network of terminals that provide fair and equal access for all above-rail operators,” Erin Flaherty, Chair of the Moorebank Intermodal Company says. “We will work closely with industry to increase the movement of freight by rail as it provides a cost effective and more sustainable transport mode for many customers,” she adds. “National Intermodal will work with the federal, state and local governments, the

Australian Rail Track Corporation, aboverail operators and industry to ensure commercially sustainable, fit-for-purpose terminals are delivered.” The Federal Government says its investments in the terminals will improve “freight outcomes” and “productivity” as well as increase competition in the sector by ensuring open-access arrangements across the network. Complementary intermodal terminals in Melbourne and Brisbane will further support the Federal Government’s investment in Inland Rail, which will create more than 21,500 jobs at the peak of construction with a potential boost of more than $18 billion to GDP during construction and over the first 50 years of operation. These intermodal terminals will play a role in the consolidation, storage and transfer of freight between rail and road at the beginning and end of each rail journey.

The Corporation will support the delivery and operation of intermodal terminals for Inland Rail.

The terminals will also provide connectivity to ports, regional networks and other capital cities and locations. The Inland Rial project is Australia’s largest freight rail infrastructure project and will consist of over 1700 kilometres of rail connecting Melbourne and Brisbane via regional Victoria, New South Wales and Queensland. Construction on the Inland Rail Project commenced in 2018 and is anticipated to be completed in 2027.

TUNNELLING STARTS FOR THE WEST GATE TUNNEL The largest tunnel boring machine (TBM) in the Southern Hemisphere has started digging the West Gate Tunnel in Melbourne. The massive TBM, named Bella, was sent on its journey under Melbourne’s western suburbs to build the alternative to the West Gate Bridge. The West Gate Tunnel Project will deliver an alternative to the West Gate Bridge in Melbourne.

ROADS APRIL 2022

It is now working its way through the earth below Yarraville and will travel for 18 months, excavating the four-kilometre outbound tunnel that will meet up with the West Gate Freeway in Altona North. The second TBM, named Vida, will soon begin work on the 2.8-kilometre inbound tunnel. The TBMs are named after Bella Guerin and Vida Goldstein. The TBMs are 15.6 metres in diameter and 90 metres long, weighing in at 4000 tonnes each, which is about the same as 20 Boeing 747 airplanes. They are equipped with a state-of-the-art computerised navigation system and will dig through an average of nine metres per day. They have been specifically chosen for their ability to work deep underground with almost no disturbance above ground for traffic, businesses and residents.

The TBMs are being piloted by a highly trained specialist crew who will work around the clock while the tunnel is being built. While the TBMs bore through the earth, a mobile factory behind them will install massive concrete rings to form the structural and waterproof lining of the tunnel. Crews of up to 20 people will then work to build the road surface and install electrics, ventilation and safety systems. Excavated soil will be taken to a specially built facility operated by HiQuality in Bulla. The TBMs have been through a thorough testing and commissioning phase within the project site in Yarraville to ensure they’re working effectively before commencing their journey. A joint venture consisting of John Holland and CPB Contractors is the subcontractor delivering the project.

REMAINDER OF THE OUTBACK WAY TO BE SEALED The Western Australian Government has partnered with the Commonwealth Government to seal the remainder of Outback Way as part of a $678 million project to deliver a new strategic transport and tourism route with the eastern states. The Outback Way is made up of seven interconnecting roads from Winton, Queensland through to Alice Springs in the Northern Territory and finishing in Laverton, Western Australia. The track cuts right through the middle of Australia and totals 2800 kilometres. The Federal Government has allocated $400 million to complete the 872-kilometre seal through Western Australia, with the WA Government committing a further $100 million towards the project. The remainder of the funding will help seal the road in the Northern Territory and Queensland. This additional funding builds on the $330 million invested by the Federal Government since 2013 to seal over 600 kilometres of Outback Way. In Western Australia, about $52 million has so far been spent to upgrade the

route, with an additional $112 million already allocated for works over 147 kilometres through to 2025-26. Deputy Prime Minister and Minister for Infrastructure, Transport and Regional Development, Barnaby Joyce, said $124 million of the fund will be spent on upgrades in the Northern Territory, creating 442 jobs. “These upgrades will spark new opportunities for industries along the route, including the critical earth precincts north of Alice Springs, the gold precincts around Laverton and the massive beef industry, while ensuring communities and people on the corridor

have better access to supplies,” the Deputy Prime Minister said. The road is critical in providing access to remote Aboriginal communities, with sealing to improve access to health and other services, while opening up rich mineral deposits east of Laverton. Work on the project is also providing ongoing employment and training opportunities for local Aboriginal people. The project will see a new road link to the eastern states, which will provide a new freight and tourism route. The entire 872-kilometre connection within WA will be sealed over the next seven years.

PORT OF MELBOURNE TO EXPAND CAPACITY Port of Melbourne has awarded a contract for development works at Webb Dock East to reduce port congestion and accommodate larger ships at the port. The works will help reduce congestion and accommodate larger ships at the port.

ROADS APRIL 2022

The contract for the works has been awarded to Fitzgerald Constructions Australia and involves demolishing a redundant section of concrete and extending the quay line by 71 metres. When completed in the third quarter of 2023, the development will allow the port to have two ships berth at the same time, improving efficiency at Australia’s largest container and general cargo port. Port of Melbourne CEO Saul Cannon said the project was an important part of a 30-year investment strategy, designed to create a more efficient and productive port that helps to strengthen Victoria’s economy. “Now more than ever, we need to make sure we get essential goods delivered to hospitals, businesses, schools and homes. “We are seeing a rising number of

larger vessels calling at the port and our current infrastructure at Webb Dock East at times does not allow for two ships to berth at the same time. For example, this project will enable two larger vessels to berth at the same time at this part of the port, reducing wait times for the ships to dock,” he said. Webb Dock East was designed as a two-berth terminal. This project will restore Webb Dock East’s intended design capacity. The Webb Dock East project is the third of nine projects that form the 2050 Port Development Strategy – a blueprint for ensuring the port stands ready to accommodate the needs of a growing city and continues to make a major contribution to Victoria’s social and economic prosperity.

CIRCULAR ECONOMY:

NO TIME TO STROLL DR. ANUMITRA MIRTI, AN ENVIRONMENTAL AND CLIMATE RESILIENCE SPECIALIST AND BECA’S NEWLY APPOINTED SUSTAINABILITY ADVISOR, SHARES HER INSIGHTS ON THE STATE OF CIRCULAR ECONOMY IN THE ROADS AND INFRASTRUCTURE SECTOR.

r. Anumitra Mirti joined Beca earlier this year to lead the group’s first dedicated decarbonisation and sustainability advisory service in Australia. As a researcher with the University of New South Wales, she has studied the impact of climate change and extreme weather events on infrastructure health. In her former capacity as Strategic Environmental Planning Manager for the Central Coast Council in New South Wales, she has helped deliver projects on climate change, sustainability, disaster resilience and greening visions. She is now excited about the prospect of helping implement circular economy frameworks through projects and initiatives led by Beca. More broadly, she’s invested in creating a wider impact on the industry by helping facilitate decarbonisation strategies for Beca’s clients. “I want to make real impact on the ground, and to eradicate the narrowness in thinking,” she tells Roads & Infrastructure. As one of Asia Pacific’s largest independent advisory, design and engineering consultancies, Beca helps deliver major road, highway, railway, bridge and airport projects within the region. As such, the group’s initiatives have a high impact on the market and the rest of the industry. “At Beca, we have a sustainability strategy, which focuses on both Beca’s performance – which we call our footprint, as well as on how we create impact in the market – which we refer to as our handprint,” says Mirti. “I joined Beca because of the opportunity to influence across sectors. Beca is at the forefront of delivering critical infrastructure projects, so I believe Beca’s role is to be

ROADS APRIL 2022

part of the solution, working with upstream and downstream clients to facilitate conversations around decarbonisation.” It is through this advisory role that Mirti is looking to generate collective impact on moving the infrastructure sector towards circularity. The first step, she says, is acknowledging that the pace of change needs to accelerate. “Infrastructure projects are responsible for 70 per cent of Australia’s annual greenhouse gas emissions. With hundreds of billions of dollars committed to infrastructure and construction projects, there’s a real opportunity for us to be innovative and bring new ideas into the future. This is the least advanced area where we can facilitate net zero thinking and meet our goal of limiting global warming to below 1.5 degrees Celsius,” she says. And yet, major hurdles remain on the way, particularly with respect to the use of secondary construction materials that have zero, or lower, greenhouse gas emissions. IMPACT OF MATERIALS The steel, cement and aluminium industries each produce about seven to nine per cent of annual global greenhouse emissions. This embodied carbon is in addition to emissions produced in the process of transporting materials to project sites. Cement, as one of the key ingredients of any construction project, remains highly carbon intensive. The burning of limestone to create quicklime – a key ingredient of cement – released significant amount of carbon dioxide into the atmosphere, leading to direct emissions from cement production.

Dr. Anumitra Mirti has been appointed to lead Beca’s decarbonisation and sustainability advisory service in Australia.

“Forget about everything else. If we continue to use cement, we are not going to be able to meet our target for 2050,” says Mirti. Realising the need for construction materials to align with net zero carbon targets, the World Wide Fund (WWF) last year initiated the formation of Materials and Embodied Carbon Leaders’ Alliance (MECLA), which is supported by the New South Wales Government’s Department of Planning, Industry and Environment. The goal of MECLA is to bring different sectors together across the building and construction supply chain to gain a better understanding of barriers to uptake. Observing that the initiative is a “good start for bringing industry together,” Mirti says

COVER STORY

finding green substitutes for construction materials requires a systemic approach to overcome barriers from a legislative and technical perspective. “Take the case of Beca for example. As a company delivering critical infrastructure, Beca’s goal is to implement infrastructure that utilise products with low carbon intensity. On the supply side, we buy material locally wherever possible to reduce our carbon footprint. Likewise, when we deliver an asset for our client, we want to make sure that we are delivering a net zero service to them so that we are not putting the burden on the client to continue with emissions from that project. But our decisions can be compromised by what is available in terms of policy framework.” SEARCHING ALTERNATIVE MATERIALS With some key construction materials in short supply – either in short, medium or long term – access to clean secondary material is another issue Mirti says the sector needs to consider. “Fly ash is fast become a secondary material to make cement and maintaining our roads. But as a by-product of coal production, access to fly ash will be limited in the coming years when coal mines in Australia close eventually,” says Mirti. “A parliamentary inquiry conducted last year found that in New South Wales alone, we have about 200 million tonnes of fly ash stored just in the Hunter Region. But most of this fly ash is not the clean material used for cement production, rather it’s coal ash, which is a toxic waste. So, we might only have

access to clean fly ash for less than ten years or so, unless you import it at premium price and high carbon footprint.” While there have been positive strides in recent years to incorporate recycled material into infrastructure projects, Mirti says the knowhow is still at its infancy. “While we have dipped our toes into repurposing waste material such as glass and soft plastic in infrastructure – a process that was accelerated following the 2017 waste import ban from China – we are still at the beginning of that learning curve. While countries in northern America and Europe are moving much faster, we are strolling. We need a leapfrog approach to fast-track the transition to circularity,” she says. “It’s positive to see local, state and federal governments testing low-carbon materials and recycled materials in road designs. But to move beyond these trials, technical specification is required. Currently, we are at the juncture of building that knowhow. With innovation funds flowing from state and federal governments, together with the backing of our academic sector and the data available from local trials and from other countries, we can mobilise that transition.” THE MISSING INGREDIENT Mirti says it’s promising to see a growing appetite for circularity in infrastructure projects, especially within roads and transport. The missing ingredient, she says, is the urgency to fast-track implementation by creating the right mechanisms. “As of last year, all of our states had come up with very strong policy positions. The

New South Wales Government’s Waste and Sustainable Materials Strategy sets strong directions for secondary material use. Queensland’s Waste Management Resource Recovery Strategy provides a framework for the state to become a zero-waste society,” she says. “Victoria is leading in this space, being the first government to create a Circular Economy Act in 2021. Another good example from a circular economy perspective is from Geelong, which was the first Australian city to provide an innovative procurement model for 100-year maintenance-free pedestrian bridges,” she adds. The next step, she observes, is for all key stakeholders to come together to create collective knowledge of how to transition from the trial phase to implementation phase. “Implementing circular economy is complex, because currently in Australia we are trying to fit circular solutions into a linear system and it’s not going to work. We need to re-think the entire system. Everyone is still working in silos and the overall approach so far has been reactive rather than proactive,” she observes. “Positive change is happening across the sector, but so far, it’s been moving more like a tornado, making only partial and localised impact. If we want to leap forward, we need to move collectively like a cyclone.” * This is the first in a series of articles with Beca’s experts to look at the state of circular economy in roads and infrastructure and the next steps for implementation. roadsonline.com.au

or the daily commuter in Brisbane, transportation in and out of the city during peak hours can usually be described as challenging. With limited options for road and public transport access, the city requires an expansion of its current infrastructure. Luckily, one suitable project is already in development and is set to transform the way in which commuters can access the city. The Cross River Rail project, due to come online by 2025, aims to release the growing pressure on the city’s current public transport infrastructure. The population in South East Queensland is forecast to grow from 3.5 million today to 4.9 million in 2036, with 45 per cent of jobs growth expected to be concentrated inside the Brisbane metropolitan area. To ensure that the public transportation requirements of the region were met, the

original proposal for the $5.4 billion project was chambered in 2010. Following further amendments, the business case for the project was released in August 2017. The plan detailed the construction of the new 10.2-kilometre rail line from Dutton Park to Bowen Hills, which includes 5.9 kilometres of twin tunnels under the Brisbane River and the CBD, as well as the construction of four new underground stations, six Southside station rebuilds, three new Gold Coast stations and two station upgrades. Currently more than 2500 workers are situated at 15 active worksites. Additionally, more than 300 apprentices and trainees have contributed to the project. Cross River Rail has also provided a significant boost to the region’s economy, with more than 1500 Queensland subcontractors and suppliers benefitting from the project to date.

Cross River Rail Delivery Authority CEO Graeme Newton says the project will serve to remove the growing stress on the city’s current rail network. “Cross River Rail is essential because Brisbane is growing to a stage where the notion of just driving a car and parking in the city is just not achievable anymore. The main highways and motorways are becoming more congested, so we need to provide an alternative mode of transport,” Newton says. “It really is about solving a transport problem, while building new stations and then driving economic development.” Brisbane’s current rail network is already nearing capacity and is constrained by a single river crossing and just four inner-city stations. The Cross River Rail project will unlock this bottleneck by delivering a second river crossing, allowing more trains to run more often. roadsonline.com.au

2021 was known as the ‘year of tunnelling’ for the Cross River Rail project.

As Newton says, the current bottleneck is the result of previous planning and construction of the rail network more than five decades ago. “The original rail design consisted of two networks, one from the north and one from the south,” he says. “In the late 1970’s, the bridge was built to link the two together. But with that design, we ended up with stations which are in inconvenient locations for commuters.” Newton says the Cross River Rail project will help the city of Brisbane to transition to a central transport hub for the region. “The analogy that we like to use is that projects such as Cross River Rail help a city like Brisbane to mature from adolescence into an adult,” he says. THIRD YEAR OF CONSTRUCTION The Cross River Rail project is entering its third year of construction, following the completion of a year known across the project as the “year of tunnelling.” As part of this phase, two 1350-tonne Tunnel Boring Machines (TBMs) dug twin tunnels 3.8 kilometres beneath the Brisbane River and CBD from Woolloongabba to Northern Portal. Additionally, two 115-tonne road headers excavated almost 900 metres of twin tunnels south from Woolloongabba to Boggo Road. Both excavations were essential in the construction for the four new underground stations at Boggo Road, Albert St, Roma St, and Woolloongabba. Newton says the machinery served as an appropriate solution to break through 18

the area’s tough rock interior. “In Brisbane the foundation below us is predominantly rock. So using TBMs is a really efficient mode of excavation,” he says. He adds that the TBMs provided great benefits for the project’s bottom line. “For projects such as tunnels or dams, the geotechnical risk is very high. If a contractor was to get this wrong, it would cost the project dearly in terms of time and money,” he says. “It’s good to have that geotechnical risk put to bed early in the project and using a double shielded TBM, such as the ones used on this project, gave a high degree of certainty of success.” This year, the focus will be shifted to station build and tunnel fit out. These works will

also include waterproofing and installing mechanical and electrical equipment. GOING GREEN During the planning of the Cross River Rail project, methods of minimising the ecological impacts during construction were prioritised. Every year in South East Queensland around 40,000 tonnes of glass ends up in landfill. The project aimed to change this by trialling the use of sand made from recycled glass as pipe bedding fill for stormwater pipe relocations. As part of the excavation works, 98 per cent of the Roma Street construction and demolition waste by weight was diverted from landfill. This included 104,146 tonnes of concrete and 5,571 tonnes of metal being recycled.

PROJECT REPORT

Further works saw 90 per cent of Boggo Road construction and demolition waste and 84 per cent of Woolloongabba construction and demolition waste by weight diverted from landfill. Spoil from the project’s TBMs was also reused by Austral Bricks, a south Brisbane brick company, with nearly 60,000 cubic metres of the material remade into brick products. BUILDING A WORLD-CLASS CITY Cross River Rail will also serve to provide optimal efficiency for commuters attending sporting and entertainment events throughout the Brisbane CBD. “This project adds the features that a good city needs. A railway station which connects to all of its main sporting and entertainment venues, and ease of interchange between different modes of transport,” Newton says. “When you go to world-class cities, you can see that these are some features they all have. It’s the aspiration for Brisbane to move to that next stage of becoming a world-class city.” Newton says that part of this “world-class” city vision is having the ability to host and contend for international events, such as the Olympic Games. On 21 June 2021, Brisbane officially received the rights to host the 2032 Olympic and Paralympic Games from the International Olympic Committee (IOC). As part of her address to the IOC, Premier Annastacia Palaszczuk specifically mentioned Cross River Rail as one of the reasons why Brisbane would be a suitable host city for the games. Newton believes that while the project was in development well before the bid to host the games was submitted, it played an essential role in securing the hosting rights. “The Cross River Rail project allows those venues to be established and operational, so that by the time we get to Brisbane 2032, the city has reached a level of maturity to host a fantastic Olympic and Paralympic Games,” he says. “It’s making the transport journey seamless, and rail is the public transport of choice when you are trying to move large crowds of people in and out of venues.” The new and upgraded stations will improve access to at least four existing venues earmarked for the events. The new Woolloongabba underground station connects to The Gabba, earmarked for the athletics events and ceremonies.

sevens and football finals. The upgraded Exhibition station is the best way to access the RNA Showgrounds and Victoria Park (equestrian and BMX freestyle) and the upgraded Yeerongpilly station links commuters to the Pat Rafter Arena (Queensland Tennis Centre). Additionally, Roma Street is also the proposed location for a new 18,000 seat indoor arena, which will host the swimming and water polo games during the 2032 Olympics. Newton emphasises that while the project will provide a significant boost for Brisbane’s infrastructure in the lead up to and during the games, the benefits will continue over the decades to come.

“It’s not just about the 2032 Olympic and Paralympic Games. Though the games do act as catalysts, it’s more about the long-term future of the city.” Despite his 30 years’ experience as a senior executive in the infrastructure sector, Newton says he is still amazed at the scope and impact of Cross River Rail – a project he says is a “real adventure” at times. “To be part of something that will change the way the city will operate in the future, is something I haven’t been able to fully comprehend yet,” he says. “This is a world-class project, being delivered by world-class people. To be associated with that type of knowledge and experience is a real privilege for me.” roadsonline.com.au

PUMA BITUMEN’S APPROACH

TO CARBONNEUTRALITY

Puma Bitumen has completed a lifecycle analysis of its bitumen supply chain to report accurate emissions for each of the company’s products.

ROADS & INFRASTRUCTURE SPEAKS TO DR ERIK DENNEMAN, GLOBAL TECHNICAL MANAGER AT PUMA BITUMEN, ABOUT THE COMPANY’S LATEST MOVE TO HELP PAVEMENT PROVIDERS ACCOUNT FOR THEIR CARBON EMISSIONS

he race to cut carbon emissions is gaining momentum globally. Industries, including the construction industry, are increasingly responding to the urgency placed by governments, as well as by their investors, to implement measures aimed at achieving net zero emissions. Reinforced by the 2021 United Nations Climate Change Conference, more commonly referred to as COP26, last year proved to be a banner year for corporate action on climate change. As of February 2022, there were 2000 businesses and organisations worldwide working with the global Science Based Targets initiative (SBTi) to set clear paths to reduce their emissions in line with the Paris Agreement goals. This number stood at 1200 companies two years prior. In a collaborative report with the University of Oxford, the UK-based nonprofit Energy and Climate Intelligence Unit estimates that at least one fifth (21 per

cent) of the world’s 2000 largest public companies have now committed to meet net zero targets by 2050. In Australia, nearly a third of the 300 largest listed companies have committed to net zero emissions by 2050, according to Macquarie Group data. The fresh urgency across the corporate world follows renewed momentum among investors as research points to a quickening pace in global warming. Net zero emissions, in simple words, is agreeing to not add new green-house gas (GHG) emissions to the atmosphere. This can be done by reducing the emissions or balancing new emissions by using natural carbon sinks like forests and oceans to absorb them. The UN has asked the world to aim for net zero emissions by 2050, which would help limit global temperature rise to 1.5C above pre-industrial era levels and in turn limit the impact of climate change.

Dr Erik Denneman, Global Technical Manager, Puma Bitumen.

ACCOUNTING FOR EMISSIONS While setting targets is a first step, companies also need detailed plans on how emission reductions will be achieved. Within the world of civil construction, roadsonline.com.au

The majority of Puma Bitumen’s bitumen supply is carried out using its own fleet of bitumen vessels.

two options, firstly a shift to renewable energy and secondly, a greater use of lowcarbon or carbon-neutral – or in some cases, carbon negative – products are being favoured. As Dr Erik Denneman, Global Technical Manager at Puma Bitumen observes, moving to low-carbon raw material for construction has a positive cascading effect for businesses that aim to achieve net zero emissions. And the first step, he says, is accounting for the actual emissions. “To achieve net zero emissions, you first need to know how much emissions your business is producing. For our bitumen products, that’s an area we are trying to help companies gain more clarity,” he tells Roads & Infrastructure. To this end, Puma Bitumen, as part of global business Puma Energy, recently completed a lifecycle analysis of its bitumen supply chain, taking account of GHG emissions produced at every stage of production and supply, from the extraction and refining stage, all the way to transportation and storage. This, as Dr Denneman explains, was made possible with a high degree of accuracy given the vast majority of Puma Bitumen’s bitumen supply is carried out using its own fleet of bitumen vessels, the largest in the world, and where charters are used, detailed reporting of GHG emissions are required from the charter party. The bitumen is stored at terminals operated by Puma Energy, or its 22

ROADS APRIL 2022

parent company, Trafigura. “When bitumen is transported and stored at elevated temperatures at our terminals, all of those stages have a certain carbon footprint. We went through a detailed lifecycle assessment of our supply chain, so that for every Puma Bitumen product, we can calculate and report exactly how much carbon was emitted,” he says. The emissions assessment helps Puma Bitumen’s customers to calculate their own carbon footprint accurately, thus allowing them to take realistic measures to reduce and compensate for those emissions. “With this information at hand, we will eventually prepare Environmental Product Declarations (EPDs) for each bituminous product in our portfolio, which helps the end-users as they prepare their environmental impact reports,” says Dr Denneman. We also have a very strong focus on warm mix additives, which allow the asphalt plants to reduce their emission production.” Across the larger Trafigura group, the goal is to reduce operational Scope 1 and Scope 2 GHG emissions by 30 per cent by the end of financial year 2023 compared to 2020. The company also aims to reduce shipping emissions (Scope 1 and 3) by 25 per cent by 2030 compared to the 2019 International Maritime Organization industry baseline and to own and operate six zero emissions vessels by 2030.

OFFSETTING OPTIONS Following the initial step of identifying their carbon footprint, businesses often look at options to reduce the carbon intensity of their operations. While emissions reduction across the supply chain is a priority, there comes a point where carbon abatement is no longer technically or economically viable. Here, Dr Denneman says Puma Bitumen is now offering customers the option to offset their residual emissions by offering a diverse portfolio of carbon offsets. Carbon markets allow carbon emitters to offset their unavoidable emissions by purchasing carbon credits arising from projects targeted at removing or reducing GHG from the atmosphere. Puma Bitumen offers customers the option to compensate their emissions with offset projects that have been registered on leading voluntary registries such as Verra, Gold Standard, ACR and CAR as well as Australian Carbon Credit Units (ACCU), which is a carbon offset project undertaken as part of the Australian Government’s Emissions Reduction Fund. Key projects may include renewable energy, forest conservation and restoration. Aside from reducing carbon from the atmosphere, these projects can also present opportunities to deliver impact across other sustainable development indicators such as protecting biodiversity and supporting local communities. Customers can then choose which projects to support depending on their corporate objectives. MOBILISING ACTION Already, Dr Denneman observes, there’s been interest from companies in Australia to make use of the available options offered by Puma. “In all honesty, the interest has been a lot higher than we anticipated. Companies are certainly responding to the UN’s call for voluntary emissions reduction,” he says. He also points out to the importance of regulatory action. “From what we have seen globally, where there’s more incentive to account for carbon emissions in the companies’ proposals as they bid for projects. There’s good progress being made here in Australia by organisations such as the Infrastructure Sustainability Council and the Australian Flexible Pavement Association to encourage project owners to select bids by best value, rather than by lowest cost,” he says.

CITYWIDE ASPHALT GROUP HAS BEEN PROMOTING WIDER USE OF HIGH-RECYCLED CONTENT ASPHALT WITH ITS GREENPAVE PRODUCT PORTFOLIO. THE PRODUCTION TEAM SHARES ITS VIEWS ON HOW THE INDUSTRY IS EMBRACING SUSTAINABILITY. Citywide Asphalt Group’s plant supervisors offer their first-hand view on how the sector has been changing.

ver the past five and a half years since the launch of Citywide Asphalt Group – a joint venture between Citywide Service Solutions and Fulton Hogan, the group has gone on to expand its portfolio of green asphalt products. Today, the company has one of the largest numbers of specialty asphalt mixes with high recycled content in its portfolio, which it manufactures from plants in Laverton and North Melbourne. Citywide Asphalt Group’s GreenPave range comprises a number of sustainable asphalt products, featuring highly engineered binders, reclaimed asphalt pavement (RAP) and asphalt made with locally sourced recycled glass, plastics, slag and rubber from used tyres. Reflecting on the product expansion and the industry’s uptake of sustainable asphalt, Tim Ogun, Citywide Asphalt Group’s Operational Improvement and Business Development Manager, says there are positive signs the industry is embracing innovative asphalt mixes at a steadily growing pace. On a recent project, the team supplied approximately 250 tonnes of GreenPave U, a dense-grade asphalt product with up to 55 per cent recycled content – the highest in the GreenPave range – to BA Road Services who were providing sustainable surfacing solutions to the Greater Shepparton Council. “GreenPave U is one of the latest additions to our GreenPave range and it contains a large quantity of RAP, glass as a partial sand replacement, plastic additive in the form of processed consumer waste products and slag. The combination of these ingredients has proven to perform

“WE’VE ALREADY SEEN VICROADS INCREASE THE MIXES WITH RECYCLED CONTENT THAT WE CAN REGISTER. I THINK IT’S A STEADY CHANGE IN THE SECTOR AND IT’S BEING DRIVEN BY COMPANIES LIKE US, WHO ARE KEEN TO PUSH THESE INNOVATIVE PRODUCTS TO THE MARKET.” very well on busy roads, where the addition of slag contributes to skid resistance,” Ogun explains. “Our GreenPave U product has been used by Greater Shepparton Council in creating a local streetscape which showcases products with higher-than-normal recycled contents in the urban environment. The product was placed by BA Road Services, an indigenousowned business, under their contract with the Greater Shepparton Council. The project has been an important first step in using GreenPave U,” he adds. In addition to using GreenPave U asphalt for the wearing course, the ‘Greener Roads’ project by the Greater Shepparton Council also used concrete with up to 40 per cent supplementary cementitious materials for the construction of kerbs, crossovers and drainage pits. The project, as Ogun notes, showcases how councils across Victoria are opening up to trial innovative asphalt mix designs. “We are seeing more councils like the Greater Shepparton Council that are committed to trialling green asphalt products for their environmental benefits. In this case, the contractor BA Road Services was instrumental in introducing our product to their client, but the council was also keen to work with us on the logistical side so we could ship the product from Melbourne to Shepparton,” says Ogun. Ogun also sees change happening at the state government level. “We’ve already seen VicRoads increase the mixes with recycled content that we can register. I think it’s a steady change in the sector and it’s being driven by companies like us, who are keen to push these innovative products to the market.” LEADING FROM THE FRONT Apart from GreenPave U, Citywide Asphalt Group’s range currently includes GreenPave G, asphalt made with locally sourced glass blended with reclaimed asphalt; GreenPave PB, a blend of hard plastic into a specialised binder; GreenPave PA, made using plastic from post-consumer products and waste; GreenPave CR, utilising old tyres blended into a binder; and Greenpave

HR, made with a higher than usual percentage of reclaimed asphalt. Citywide Asphalt Group has also recently introduced GreenPave Cold, a cold mix asphalt with glass as a sand replacement that also incorporates canola oil sourced from local Victorian farms to replace diesel. Apart from being a safe and environmentally friendly solution, the mix offers extended shelf life and improved workability characteristics. With Citywide Asphalt Group a key supplier of cold mix asphalt in Melbourne’s metropolitan area, Ogun says the introduction of GreenPave Cold will have significant benefits for the industry. So how does it feel to be on the innovative edge of producing sustainable asphalt products for the industry? Citywide Asphalt Group’s plant supervisors have firsthand experiences of how the sector has been changing. Andrew Totino, who has been in the industry for over eight years, with the last two years as supervisor for Citywide Asphalt Group’s North Melbourne plant, says the size of projects where specialty mixes are adopted is increasing. “The asphalt industry has always been trying to include recycled components in the mixes. Recycled asphalt is very common in the mixes and has percentages used as a standard, but we also have inclusions such as crumb rubber, plastic, glass, slag and high RAP,” he says. “The difference from when I first started to now is that initially the inclusions were only used for small projects, but now it’s widely asked for from clients and is often a requirement for a lot of the contracts.” Charbel Bou-Ghosn, the supervisor of Citywide Asphalt Group’s Laverton plant, is another veteran of the industry. He has been supervising asphalt production for the past 15 years. “I have seen a lot of changes in recent years, especially with different types of recyclable products that come into use to reduce the impact on the environment,” he observes. “Citywide’s mixes can be created with different types of recyclable products. We are trying to create more suitable solutions for our clients to help their efforts and

grow our industry into using more and more recycled products, while maintaining strong, reliable products,” he adds. James Tomeo, another member of the Citywide Asphalt Group team, sees positive improvements happening in the sector. “In the short time I have been with Citywide, there has been some positive improvements with regards to supply to our ongoing clients. We have been able to provide clients with high quality PMB mixes, while continually trying to improve our safety in the workplace. A key factor to this is the company’s focus on continuous improvement and helping us as individuals to achieve our career goals and supplying us with efficient training.” As for the broader industry, Ogun believes uptake for high recycled content asphalt mixes will increase in the coming years. “The uptake has been slow, but steady. But I believe the pace of change will increase. It’s like when you go shopping and you tend to stick to what you know, but sometimes you try something new, and it wins you over. That’s where the sector is right now,” he says. “We understand why some clients are hesitant, but our results and trials are there to prove the performance of our products. As the sector embraces the environmental benefits of innovative asphalt mixes, we want to be part of that process of change. We want to drive it forward.” roadsonline.com.au

SAMI has been implementing measures to minimise emissions from its import, storage and manufacturing processes.

SUSTAINABLE BITUMEN SUPPLY:

LESSONS FROM SAMI SAMI BITUMEN, A LONG-TERM SUPPLIER OF BITUMEN PRODUCTS IN AUSTRALIA, IS KEEN TO PLAY ITS PART IN MORE SUSTAINABLE BITUMEN DELIVERY FOR ROAD CONSTRUCTION. HERE’S A LOOK AT THE COMPANY’S BITUMEN SUPPLY CHAIN FOR MORE INSIGHTS.

very year, Australia uses more than 800,000 tonnes of bitumen for asphalt and sprayed sealing applications. With all this bitumen imported from overseas, bitumen importation and storage processes have an impact on the overall sustainability of road infrastructure. SAMI Bitumen Technologies, as the first independent bulk bitumen supplier in Australia, has been involved in importation of bitumen to Australia since 2005. The company’s facilities in Brisbane, Kwinana, Fremantle, Sydney and Geelong have a combined capacity of over 50,000 tons for bulk bitumen storage. Apart from supplying all bitumen grades as specified in the Australian Standard AS2008 – including multigrade and EME(Enrobés à Module Elevé) grade bitumen – SAMI’s facilities also manufacture a range of speciality bituminous products, such as polymer modified binders, emulsions and polymer modified emulsions. As part of a broader company mission to cut greenhouse gas emissions by 30 per cent by 2030, SAMI has been implementing a series of measures to minimise emissions

from its import, storage and manufacturing processes. The goal, as Scott Olsen, SAMI’s State Manager for Western Australia explains, is to achieve emission reductions across the entire SAMI supply chain. “SAMI’s is a cradle-to-grave solution across the entire network,” he says. “From having due consideration in picking our source refineries and transport options, to installing solar panels on our storage sheds and helping with reduction or removal of kerosene use in sprayed sealing applications with our products, SAMI has been progressing on all fronts towards greater sustainability,” he tells Roads & Infrastructure. As a supplier of crumbed rubber modified binders, Olsen says recycled tyres account for about 30 per cent of SAMI’s annual production by tonnage. SAMI has also developed sprayed sealing binders that eliminate the use of petroleum-based solvents for sprayed sealing operations, thus preventing the emission of solvent into the atmosphere. “SAMI has been pioneering in the introduction of speciality hard-grade binders, which enable high modulus asphalt

to be used in heavy-duty pavements. This helps reduce the pavement thickness by up to 25 per cent, thus helping minimise use of non-renewable products. Other examples of sustainable SAMI solutions include developing micro surfacing binders to enhance skid resistance and extend the service life of the road surfac, as well as developong the environemntally friendly BioPrime solution to replace kerosene-based bitumen cutters for priming purposes,” says Olsen. THE SAMI PROCESS Olsen, who also oversees SAMI’s bitumen shipments and storage via Kwinana and Fremantle Port in Western Australia, says all of SAMI’s bulk bitumen is imported from carefully selected refineries, predominantly in Asia. “Having the majority of our sources located locally within Asia helps reduce our carbon footprint from transport,” he says. “Additionally, we have been studying bitumen fume emissions over the past few years to develop predictive models that are used for the selection of bitumen sources.” roadsonline.com.au

ENVIRONMENT & SUSTAINABILITY

In pursuing its goal, SAMI also enjoys the global support of its parent company, the Colas Group. Colas’ subsidiaries own and operate a fleet of bulk hot bitumen shipping vessels. Having recently added LNG-fuelled bitumen cargo vessels to its fleet, Colas is expecting the initiative to help cut carbon dioxide emissions by 30 per cent compared to using oil fuelled cargo ships. Tiffany Pham, Bitumen Procurement Manager for SAMI, says apart from enjoying a greater control over the shipping process, the partnership between Colas and SAMI also ensures access to reliable sources. “When it comes to imports, SAMI is focused on delivering quality products compliant to the Australian specifications. We carefully select our source refineries, where we procure bitumen under mediumto long-term arrangements, to ensure that the material provides the best performance and value for our clients. Our bitumen is usually shipped by a fleet of cargo carriers owned by our parent company. This provides us the advantage of not compromising quality due to constraints on procurement and transport,” she points out. “In addition, our parent company owns and operates a dedicated bitumen refinery in Asia, which guarantees an ongoing supply of bitumen into Australia. This is critical with uncertainty surrounding the future bitumen supply from fuel and lubes refineries,” she adds. This process, she says, ensures SAMI can maintain a reliable supply to its clients. It also helps minimise risk or shortages. RIGOROUS TESTING Product testing is another important step in SAMI recently invested heavily on its new and existing bitumen storage and manufacturing facilities.

SAMI’s parent company, the Colas Group, now has LNG-fuelled bitumen cargo vessels in its fleet.

the supply process when it comes to quality assurance, Pham says. “SAMI works with globally recognised refineries in Southeast Asia. We have longterm contracts with these refineries and in some cases partnership arrangements have been established to ensure continued long-term supply. If we want to sign up a new refinery, we first go through a process of rigorous product testing to ensure the bitumen quality is consistent with the AS2008 standard,” she explains. “We import single refinery source in each of our cargo, making sure the composition of bitumen is consistent and that the bitumen is suitable for modification with polymers and emulsifiers. Further, each cargo vessel’s load is tested for compliance to specification prior to loading. The cargo is monitored constantly while in transport to make sure the bitumen temperature remains within the recommended temperature throughout the journey. Samples are taken and tested when

the cargo arrives at our storage facilities and also before leaving SAMI’s facilities to reach the client.” SAMI also regularly tests the quality of bitumen in its manufactured products, such as emulsion and polymer modified bitumen (PMB), Pham adds. “We are fully invested in the supply chain of products derived from bitumen, so our customers have the certainty that our bitumen will give them satisfaction.” SAMI’s independent research and development (R&D) facilities, including the main SAMI laboratory in Camellia, New South Wales, provide support with binder and asphalt testing for SAMI’s clients. “SAMI’s in-house testing and product development expertise is further supported by the global network of Colas Group’s bitumen experts. Colas’ Centre of Excellence in Paris is a fully dedicated bitumen R&D centre that can support us for specialty tests,” Pham says. SAMI recently invested in its new and existing bitumen storage and manufacturing facilities. The company has also invested in a large fleet of road tankers and bitutainers to be able to supply binders to all locations across Australia and neighbouring islands. Olsen says through these investments, SAMI is prepared to play an even bigger role in improving the sustainability of Australian roads. “With the financial stimulus flowing through the Australia infrastructure industry, the market for bitumen and bituminous products is likely to grow in the coming years. With SAMI’s strong supply chain, we are ready to keep supporting the industry, like we have done since 1978.”

ROADS REVIEW

FOR THE ROAD REVIEW SECTION THIS MONTH, WE ASKED THE INDUSTRY DECISION-MAKERS, ‘WHAT FACTORS HELP THE INDUSTRY BUILD UP MORE CAPABILITY TO DELIVER THE CURRENT PIPELINE OF CONSTRUCTION WORK?’

DAVID HALLETT, CEO, INSTITUTE OF PUBLIC WORKS ENGINEERING AUSTRALASIA (IPWEA) VICTORIA Continuing Professional Development (CPD) is the key to capability development, both in technical and non-technical areas. Technical learning provides industry professionals with knowledge of contemporary best-practice in the areas of infrastructure design, sustainability and technology, while non-technical learning can address resource management, project leadership or business administration skill gaps. The regulation of built environment engineers in Queensland and Victoria brings with it a mandatory professional development obligation, but whether registration renewal is the driver or not, a commitment to ongoing professional development and lifelong learning is vital at a time of rapid, ongoing change in the construction sector.

ROADS APRIL 2022

SARAH BACHMANN, CEO, NATIONAL PRECAST CONCRETE ASSOCIATION AUSTRALIA With skyrocketing work volumes, steel and timber price hikes, an increased focus on reducing carbon emissions and a skills shortage, the post-pandemic key to boosting construction capability will be to work smarter. Fundamental changes in culture and construction practices are needed if construction productivity – which typically lags behind manufacturing productivity – is to be improved. Collaboratively embracing off-site manufactured products through engagement of industrialised construction and Design for Manufacture and Assembly (DfMA) methodologies will be key, as will be making better use of the less-price-affected available products. Using high-quality elements like precast, which are factory manufactured and simply bolted into place rather than being poured or built from scratch on site, has flow-on benefits. These include reducing site waste, lowering site activity, improving site safety while delivering higher quality, more durability, and more environmental benefits – all of which lead to superior, more energy-efficient structural outcomes.

ROADS REVIEW

MATTHEW ING, DIRECTOR, BG&E NSW Fewer available resources to deliver the current pipeline of construction work forces industry to adopt new and innovative ways to deliver designs. For instance, driving reliance on 3D modelling during the design process to reduce the number of 2D drawings will increase productivity during design, and provide efficiencies across the supply chain during construction. Designs are also being more closely scrutinised, ensuring that only elements that provide value throughout the project’s lifecycle are designed and constructed. The key to innovative and efficient design is leadership, which encourages creativity and continuous upskilling with new technology, while balancing project risks.

DR M. REZA HOSSEINI, ASSOCIATE HEAD OF SCHOOL, SCHOOL OF ARCHITECTURE AND BUILT ENVIRONMENT, DEAKIN UNIVERSITY The construction industry is the second largest industry in Australia; however, it hardly receives any attention from the Australian Research Council. Construction has not been a research priority for the government for so many years, as a result of which many researchers try to associate their projects with other fields to enhance the chance of success in attracting funding for their projects. This will have significant impact on the innovativeness and performance of the industry. Having a research-informed construction industry that is innovative can result in more efficient practices, where projects are delivered with less resources.

CHRIS MELHAM, CEO, CIVIL CONTRACTORS FEDERATION The Civil Contractors Federation encourages a joint effort between industry and governments to address some key constraints to help alleviate capability issues in our issue. First, addressing skill constraints, which are illustrated by the recent historical downturn in vocational education completions, is a significant risk to industry capability. Second, procurement constraints hinder the effective delivery of projects and increases costs to businesses, which also limits their capacity to invest in upskilling. And third, cyclical constraints, as evidenced by a historical ‘boom-and-bust’ cycle, amplifies constraints during periods of strong investment and then worsens structural issues during periods of low investment.

BIM AND INFRASTRUCTURE

DELIVERY

WITH INFRASTRUCTURE PROJECTS GROWING IN SIZE AND COMPLEXITY, VLAD MILICEVIC, DIRECTOR OF APAC REGION AT REVIZTO, SAYS THE INDUSTRY HAS NEVER BEEN BETTER POSITIONED TO EMBRACE THE BENEFITS OF DIGITAL ENGINEERING.

he use of Building Information Modelling (BIM) for managing large transport infrastructure projects is growing rapidly, and as Vlad Milicevic, Director of APAC region at Revizto sees it, there is a strong case for increased adoption of BIM tools across the industry. “We have seen significant success with the use of BIM in the infrastructure space over the past three to four years,” he tells Roads & Infrastructure. “In fact, some large rail and road projects where big engineering companies have adopted Revizto’s BIM software have been tracking so well with their reviews that the government officials were prompted to go in and see what the contractors were doing that resulted in such efficiencies.” It is through such demonstrated success that Revizto, an integrated BIM collaboration software platform introduced globally in 2014, has gained its foothold in Australia and been growing its impact on the construction sector. Using gaming technology and cloud

solutions, Revizto brings together various BIM and CAD data to track all project issues in one centralised 3D environment. What makes Revizto’s platform a “gamechanger,” Milicevic notes, is how it can handle large and complex infrastructure models while remaining user-friendly. “Linear infrastructure projects consist of a lot of models which are very large and stretched out,” he says. “Before Revizto, there wasn’t a collaborative tool in the market which could truly support the volume, complexity and size of such models – meaning that people in that space would require an internet connection that could often be interrupted by poor connectivity issues and lag. The userfriendliness of their existing platforms wouldn’t be as good either.” BRIDGING THE GAP To solve this issue, Revizto uses a gaming engine to create an immersive model for all project stakeholders, from designers

to safety officers, to visualise the project in real-time and coordinate with each other. Using cloud optimisation means the models can be accessed from any device without demanding sophisticated hardware or training.

Revizto’s collaborative environment is being used to deliver KiwiRail projects in New Zealand.

SOFTWARE

“Because of the way Revizto is built on a gaming engine, it provides users with an extremely simple experience. Anybody can pick it up and use it on different platforms, not just with laptops and desktops, but even iPads and tablets,” says Milicevic. “Revizto also supports virtual reality. Users can put on virtual reality goggles and submit their reviews that way. This capability expands not only to coordination works, but also to safety reviews. A safety manager could just walk through what is supposed to be a project site and look for any safety breaches,” he adds. A key feature with Revizto’s BIM platform, Milicevic says, is how it allows all project stakeholders to deploy BIM methodologies and technologies, regardless of whether they are in the head office, site office or out on site. “As more and more people begin to cooperate on the collaborative platform, things like constructability, which has not traditionally been part of the 3D review process, can now be accessed on a device such as an iPad. Users can directly communicate, while having a full context of how a part of a project should or shouldn’t be constructed or why a certain design solution is not going to be practical,” he explains. The result, as Milicevic sees it, is a more “democratic” access to the digital engineering process, where experienced – but less tech-savvy – engineers can easily reap the benefits of a 3D project model without having to undergo extensive training. “It’s very easy for Revizto to develop its adoption across the project team,” he says. “Because the program moves seamlessly between 2D and 3D models, it allows people who are not experts in using digital tools to reap the benefits of 3D information, while still using the traditional methods they have been using for years, which is looking at a set of drawings. The difference is they can now tap on that drawing and go directly into a 3D model and move around the project, as simple as playing a video game.” REVIZTO+ AND CLASH AUTOMATION Last October, Revizto launched a new version of its software platform that, in addition to a range of new features and upgrades, introduced the Revizto+ subscription for automatic clash detection on the 3D models. The functionality, 34

“BECAUSE THE PROGRAM MOVES SEAMLESSLY BETWEEN 2D AND 3D MODELS, IT ALLOWS PEOPLE WHO ARE NOT EXPERTS IN USING DIGITAL TOOLS TO REAP THE BENEFITS OF 3D INFORMATION, WHILE STILL USING THE TRADITIONAL METHODS THEY HAVE BEEN USING FOR YEARS, WHICH IS LOOKING AT A SET OF DRAWINGS.” Milicevic says, was developed off the back of industry feedback. “As part of our Revizto+ subscription, we have a feature called Clash Automation, which allows people to automatically run their clash automation reports. A lot of our clients have been telling us that it is a complete game-changer, because it allows them to coordinate better in one platform,” he says. “I think in the next few years, it is going to help a lot of projects get a lot more efficient.” Multinational engineering and infrastructure consulting firm AECOM is one company that has successfully implemented Revizto+. Ben May, Digital Director at AECOM, says the new functionality has fortified an already powerful software. “Revizto+ brings more functionality into an already powerful platform. The inclusion of clash automation brings efficiency to this process and enables clash resolution to be integrated into a single coordination workflow. We anticipate the need for other software will be removed. This, and the hands-on nature in running separate clash resolution processes, could remove as much as 20 per cent of the cost of a BIM coordinator’s budget,” he says. Daniel Holohan, BIM Manager at CPB, says the Clash Automation functionality in Revizto+ offers time-savings. “By reducing the coordinator’s personhours, I estimate a net saving of three to four hours per week on my projects,” he says. Patrick Fingleton, Digital Design Coordinator for Melbourne-based company IIMBE is another satisfied end-user. “Revizto+ brings so many improvements and efficiencies to the way we work. It’s intuitive and simple to perform all the required tasks. With Revizto+, I think 2030 per cent in time savings would be a conservative estimate. [It’s] simple to use and reliable. We love that you can use the data within the models to quickly build clash tests and search sets,” he says. Kyle Forlong, Digital Engineering Manager at John Holland has found multiple benefits, from supply chain

coordination to data integrity. “[Revizto+] allows the contractor the ability to better understand the supply chain’s coordination process in action. It also allows us to identify gaps in clash detection and actively add or refine tests to suit,” she points out. THE DIGITALISATION JOURNEY With the industry warming up to wider adoption of collaborative coordination platforms for efficient project delivery – particularly in this era of obligatory work-from-home and remote working conditions – Milicevic believes the technical advancements and the broader sectoral policies are moving in the right direction. “The government guidelines definitely help. The development of a BIM Strategic Framework by the Victorian and Queensland Governments and the Digital Engineering Framework developed by Transport for NSW are all tools that help get projects and organisations to the next step of utilising digital technology,” he says. “Another trend that we are seeing in recent years is the organisations realising that these platforms do deliver on what they promise. It is a tool to help people make their project deliveries more efficient. More companies are recognising the need to modernise their processes simply because they are afraid to fall behind. These companies are finding that there aren’t as many technological obstacles to adopting these technologies as there has been previously. Rather, there are a lot of efficiencies to be gained.” For Milicevic, the future of infrastructure development is going to be “digital-by-default.” “BIM is set to become such a core tenet of project delivery that, regardless of how large your business is, if you’re not capable of delivering projects in a BIM framework within five to 10 years, then you’ll be very much behind the eightball,” Milicevic says. “The future is digital by default and there’s an important education piece here, so we’re driving those conversations from our side around what BIM brings to the table.”

GREENPAVE™

BREAKING OLD HABITS WITH MORE GLASS AND LESS SAND

GREENPAVE™

GreenPave™ G asphalt mixes are made from locally-sourced glass originally used in drink bottles and jars. These are cleaned, crushed and graded to meet Citywide Asphalt Group's stringent manufacturing specifications. The glass is then cold-injected into the manufacturing process to create a uniform blend of binder, reclaimed asphalt pavement (RAP), aggregates and glass. The process is no different to the production of normal asphalt — but with the added benefit of using a high proportion of recycled materials. GREENPAVE™ G LOCAL CAR PARK PROJECT

APPLICATIONS

GreenPave™ G asphalt mixes can be used as base and wearing layers on roads and footpaths.

LINTEC & LINNHOFF EYES AUSTRALIAN SUCCESS FOR

CDP ASPHALT PLANTS

RECOGNISING THE HUGE DEMANDS IN THE MARKET, GLOBAL ASPHALT AND CONCRETE EQUIPMENT COMPANY LINTEC & LINNHOFF IS BUILDING ITS PRESENCE IN THE COUNTRY, STARTING WITH THE CDP RANGE OF CONTINUOUS ASPHALT MIXING PLANTS.

Lintec & Linnhoff is introducing its CDP range of continuous asphalt mixing plants in Australia.

he global construction industry has demonstrated remarkable resilience during the worst of the COVID-19 pandemic and is on its path to recovery. According to Future of Construction, a forecast report produced by Oxford Economics and Marsh McLennan companies Marsh and Guy Carpenter, the construction industry is set to be a global engine for economic growth and recovery from COVID-19. And within this global construction drive, Australia is perfectly placed, sitting among the top 10 global construction markets and well-positioned to accelerate infrastructure development, which has a forecasted annual growth rate of 3.4 per cent between 2020 and 2030. Recognising the huge potential and 36

demands in the Australian construction market, Lintec & Linnhoff, a global asphalt and concrete equipment company, is looking to build its presence in the country, starting with the introduction of Lintec’s CDP range

of continuous asphalt mixing plants, which are suitable for infrastructure development to suit the requirements of Australian projects. Known for their high mobility, reliability and environmental-friendly

all functions from inside the control cabin. The plants also offer remote access via the internet, so the project management team can monitor progress, troubleshoot and activate program updates from any location. Setup on-site is swift thanks to the plants’ ability to operate on solid compacted ground without the need for concrete foundations.

Lintec’s CDP5001M asphalt mixing comes with a mobile framework with built-in chassis.

features, Lintec’s CDP range tick a lot of boxes for companies looking to take on road construction projects. “We have identified Lintec’s CDP4000C, CDP5001M and CDP12000M as suitable options for the Australian market,” Lee Yen Meng, CEO at Lintec & Linnhoff Asphalt, tells Roads & Infrastructure. “These models can tackle all needs for Australian roadbuilding projects, and fulfil Australia’s high standards for sustainability.” TAILORED SELECTIONS While known for its vast expanses, Australia is also one of the world’s most urban nations, with nearly 90 per cent of its population living in cities. Connecting these centres with better roads and transport options will be key to maintaining the country’s ongoing advancement. As such, mobility and flexibility are a high priority for roadbuilders tasked with creating the huge highways that define road travel in the country. Lintec’s CDP4000C asphalt mixing plant has a production capacity of 20-40 tonnes of hot mix asphalt per hour. With its containerised design, the CDP4000C is easy to install and has a small footprint, making it a suitable choice for sites where space is at a premium. From the CDP range, this plant is the only model with all of its components housed in a 40-foot high cube sea container for easy land transportation and economic sea shipment. Meanwhile, the CDP5001M asphalt mixing plant has a production capacity of 30-50 tonnes of hot mix asphalt per hour. The ‘M’ stands for mobile, as the CDP5001M plant comes with a mobile framework with built-

in chassis, making it easy to transport and fast to install. In addition, the plant includes a bitumen and fuel tank system, turning the CDP5001M into an integrated mobile plant. For more demanding projects that require higher output capacity, Lintec’s CDP12000M is the best choice. The plant has a production capacity of 100-120 tonnes of hot mix asphalt per hour, and is designed primarily for mobile (due to its built-in chassis) but it is equally adept at stationary use, providing flexibility to the owner. Lintec’s CDP continuous asphalt plants include a cold aggregate feeding system, a counterflow drying drum with an automatic burner, an external twin-shaft pugmill mixer to help produce a more homogeneous asphalt mix, a drag slat conveyor to discharge hot mix asphalt, and an external baghouse filter for pollution control. Plant operations are automatically controlled via a Programmable Logic Controller (PLC) system that allows the operator to manage

SUSTAINABILITY IN THE SPOTLIGHT Australia’s ongoing commitment to sustainability in the construction sector is expected to continue, and with this in mind, all Lintec asphalt plants are designed with environmental-friendly features. The CDP asphalt plants have an external baghouse filter to ensure a low particulate emission rate. According to Lee, Lintec’s CDP series of continuous asphalt plants are proven performers in many other parts of the world. “For example, in Latin America, the CDP range is one of the most popular choices for roadbuilding with the CDP5001M featuring on a range of recent projects, including highway repairs in Guadalajara, Mexico, and the upgrade of the Tranche III Road in Guatemala,” he said. “The easy transportation, reliable production output and compact design of our CDP range have helped us win many customers in the Latin American market. We are confident the range can be just as successful – if not more successful – here in Australia.” Lintec & Linnhoff is a global manufacturer and distributor of solutions for the asphalt and concrete industries under the Lintec, Linnhoff and Eurotec brand names. Its products include asphalt mixing plants, concrete batching plants, pavement-related technologies and machinery, and specialist concrete cooling solutions. Lintec’s CDP12000M has a production capacity of 100-120 tonnes of hot mix asphalt per hour.

WHILE THE CURRENT MARKET DYNAMICS AND INFRASTRUCTURE INVESTMENTS ARE BOOSTING COMPETITION IN FAVOUR OF CONTRACTORS, THE LONG-TERM ISSUE OF LOW PROFIT MARGINS IN THE CONSTRUCTION INDUSTRY STILL LOOMS, SAYS MATTHEW MACARAS, SENIOR SOLUTION ENGINEER AT INEIGHT.

ustralia is in the midst of one of the greatest infrastructure booms in its history. While infrastructure spending was already playing catch-up to fill the gaps created by migration and population growth over the past decade, the pandemic and the federal government’s commitment to infrastructure investment to boost the economy in the post-COVID world has boded well for the sector. The federal government released its 2021 Australian Infrastructure Plan

in September last year, advocating for a new wave of infrastructure reform to be driven by a $110 billion investment. The government’s vision for the next 15 years addresses a range of areas for reform, including city redevelopment and expansion, housing density and public and private transport. This dynamic market condition has been welcomed by contractors, particularly the smaller and medium-sized companies, who are finding themselves in need of growth and expansion to meet the

size and scale of incoming work. And while this may have temporarily relieved some of the pressure felt by contractors to reduce their profit margins to win contracts, the underlying issue has not gone away, according to industry expert Matthew Macaras. As a Senior Solutions Engineer working with the global construction management software company InEight, Macaras deals with Australian contracting businesses of all sizes to help them streamline their project management processes. InEight’s tools help contractors minimise their project risks by creating more transparency.

PROJECT MANAGEMENT

“WHAT WE DO IS TO HELP CONTRACTORS BETTER MANAGE THEIR PROJECTS, CAPTURE ALL THE DATA IN A SINGLE SPOT AND THEN PROVIDE THEM THE REPORTING AND THE VISIBILITY TO BE ABLE TO MAKE PROACTIVE DECISIONS, AS WELL AS ALLOWING THE CHANGE PROCESS TO PROCEED SMOOTHLY.”

Matthew Macaras, Senior Solution Engineer at InEight.

He observes that the civil construction industry has long suffered from a pricefirst approach to contractor selection, while sectors such as mining, oil and gas have been quicker to adopt a value-based approach. The result, he says, is “razorthin” profit margins for civil contractors. “This is particularly true for the smaller infrastructure projects,” he says. “The contractors are going in with narrow margins, or sometimes no margins at all, to place their bids and win the projects. This then means that they’ll need to cut costs where possible and charge the asset owner with a change order processes at every step to try and recoup some of that margin and make the project profitable.” SOME RELIEF The scenario, Macaras says, has improved since more investments have started pouring in, but it may only be short-lived. “I think the reason we see conditions improving right now – and I expect we’ll start to see it taper off in the next couple of years – is because there’s just so much work that if companies don’t get the margins they expect, they don’t under-bid. They already have enough work, so more projects would stretch their resources and increase their risks. They also know their competitors are experiencing similar conditions.” Broader uptake for contract styles that help mitigate some of the risk for contractors has also been a welcomed sign, Macaras observes. “In recent times, we are seeing an increase in the New Engineering Contract (NEC) framework, which are more about owner collaboration and having early 40

ROADS APRIL 2022

warnings for changes. This makes sure changes can be resolved in a timely manner,” he says. “Similarly, in larger projects where the contracts are often either designbuild or Engineering, Procurement and Construction (EPC) type contracts, contractors are being brought in at earlier phases of the project, which allows them to help define the project scope. The contractor is still assuming some level of risk, but they can now better define that risk and price it appropriately so that they can adjust their margins later.” A SINGLE-PLATFORM SOLUTION As a solutions provider in all aspects of digital project management, from simulation to document control, planning and scheduling, InEight’s tools help contractors minimise their project risks by creating more transparency between owners and contractors. InEight’s analytics tools also allow contractors to keep track of their projects in real-time and visualise their progress. Macaras observes that using interactive and collaborative digital tools, such as those provided by InEight, contractors are finding it easier to manage their risks, recoup their costs and communicate with asset owners in a transparent fashion. “Where InEight’s capabilities as a digital tool come into the picture is by allowing contractors to see what’s happening on their projects. What we do is to help contractors better manage their projects, capture all the data in a single spot and then provide them the reporting and the visibility to be able to make proactive decisions, as well as allowing the change process to proceed smoothly,” he says. “By capturing and storing all of the project’s changes, large or small, in one platform, contractors are better able to see them through to resolution. It’s really about having that visibility and everything in the one spot so contractors can make informed decisions and be pro-active in their decision-making.”

IMPLEMENTATION PROCESS Macaras says InEight’s experts have helped many contractors combine their discrete project management processes into a unified platform or create new processes where there were none. “As a solution provider, we do not just sell our clients the tools they need and walk away, but we also help deliver the outcomes they seek. Depending on the level of the client’s digital maturity and how much involvement they expect from us, part of that delivery process might be going through a business process assessment and looking at what the business currently does and then helping configure the systems to meet their requirements,” he explains. “The implementation process always follows a dialogue, so it’s not just the contractor providing information to us and we sort it out for them. It’s a process where we have conversations with the client to bring our best-practice experience to them.” Macaras observes that the construction sector has become more receptive to digital growth in recent years. “More so since COVID, but also before that, contractors are starting to see the benefits of modernising the way they do business through connected platforms,” he says. “We are seeing that in two aspects. On one hand are the smaller contractors, who are using technology to grow and have a better picture of what’s going on in their projects, to become more efficient, have more confidence in their estimates and their forecasts, and to leapfrog competition. On the other hand, larger tier-one companies are doing it to streamline their operations and get visibility into their project portfolio.” Gone are the days of reading pages and pages of pdf reports to gain insight into projects, Macaras observes. “The way we capture project data has improved over time. But real power comes not from the data itself, but from being able to visualise that data to gain better insights. That’s where the real benefit of technology will emerge.”

Going further to achieve your Sustainability Goals We want to work with you towards achieving carbon neutrality, a term used for the practice of reducing carbon emissions in the atmosphere to compensate for emissions released elsewhere. This means that for every ton of CO2 emitted in the bitumen supply chain the industry would need to achieve an equivalent reduction in various other processes. Carbon offsets (also referred to as carbon credits) can be generated by any type of project that reduces or eliminates greenhouse gas (GHG) emissions beyond a business-asusual scenario. Through our integrated supply chain and global expertise, we are best positioned to make your sustainability goals a reality.

Infrastructure Sustainability Council

RECONNECTING

FOR SUSTAINABILITY WHAT HAPPENED AT THE INFRASTRUCTURE SUSTAINABILITY COUNCIL’S RECONNECT CONFERENCE IN SYDNEY.

ore than 300 infrastructure delegates from across Australia and New Zealand met at the Infrastructure Sustainability Council ReConnect conference in Sydney in March. A clear call to action emerged for the infrastructure sector, with Infrastructure Sustainability Council’s Chief Executive Officer, Ainsley Simpson, challenging the industry to come together around a shared vision. “Competitive advantage will not be defined by intellectual property, rather by the speed at which innovations are shared to reduce the learning curve for others,” said Simpson. TWO NEW AGENDAS The Infrastructure Sustainability Council launched two new agendas, which will be progressed through collaborative member coalitions: “Advance our nations, fair – world-class infrastructure for thriving nations,” developed in partnership with Urbis, finds industry fragmentation, subjective decision-making, risk aversion and sectoral capacity are the key barriers to world-class infrastructure performance. Launching the paper, Urbis Future State Director, Kate Meyrick, challenged the audience to remember infrastructure’s purpose. “Infrastructure is about solving problems and enabling opportunities. If we want to be a better ancestor for future generations then we need to take a more restorative approach and make far bolder decisions today,” Meyrick said. “Place-based approaches to net zero,” launched in partnership with Mott MacDonald, calls for a systemic, networked approach to decarbonisation focused on towns, cities and regions rather than just assets, sectors and materials. Amanda Sturgeon, Climate Change Practice Lead at Mott MacDonald said: “This is a call to action for the infrastructure sector to lead by example, thinking globally, acting locally in the cities and regions

which we live, work and play. “The true power of a place-based approach is that it unlocks innovation and new potential that would not be evident from a typical top-down approach, such as local business investment and community engagement in net zero solutions.” SUSTAINABILITY AWARDS Exceptional achievements within the infrastructure industry were celebrated at the Infrastructure Sustainability Council Gala Awards 2022.

Astec’s Prosizer 2514MF is a more compact version of the portable crushing and screening plant than its predecessors.

MODIFIED AND IMPROVED:

ASTEC PROSIZER IT’S BEEN A MAINSTAY OF THE AUSTRALIAN PAVEMENT AND AGGREGATE RECYCLING SECTOR FOR OVER A DECADE. NOW, ASTEC’S PORTABLE CRUSHING AND SCREENING PLANT HAS GONE THROUGH A MAKEOVER FOR AUSTRALIAN CONDITIONS, WITH BENEFITS FOR BOTH OWNERS AND THE ENVIRONMENT.

he portable ProSizer plant by Astec is no stranger to the Australian construction landscape. It has been recycling aggregates and asphalt solutions here for more than a decade. The ProSizer has also been applied in the pavement recycling sector, where it is used by road profilers and asphalt producers to process reclaimed asphalt pavements (RAP). The ProSizer – named for its “product sizer” application – incorporates a horizontal shaft impact crusher and screen on a portable chassis and trailer. Traditionally, the ProSizer has been available in three models – the ProSizer 3100, 3600 and 4200. The average dimensions of each of these models is around 20.4m x 3.4m. Last year, Astec Australia launched a compact version, the ProSizer 2514MF. At

only 17.56 metres, the 2514MF is almost three metres shorter than its predecessors. As Astec Australia Business Line Manager – Materials Solutions Adam Gordon explains, the redesign was part of Astec’s strategy to make the plant more easily transportable across every state and territory. “The new Astec ProSizer is a result of collaboration between the Astec Australia team and the manufacturing team in the US, taking in feedback from our clients and also factoring in considerations for Australia’s road transport regulations,” Gordon tells Roads & Infrastructure. “The original ProSizer was a good machine and is still suitable for the US market. But over the years, there have been more regulations imposed by different states in Australia, which made it difficult to tow the plant cross-country. With many kilometres of

spray sealed roads in Australia, we identified an additional benefit by minimising the overall trailer length to reduce any potential risk of damaging the sprayed seal surface when turning sharply. For all these reasons, we knew it was time for a redesign,” he adds. HIGHER PRODUCTIVITY For the pavement recycling industry, in particular, the 2514MF delivers benefits. As Jorge Boil, Astec Australia’s Business Line Manager – Infrastructure points out, the more compact design allows smaller asphalt producers to increase their economic returns by transporting the ProSizer from one project site to another. “A big problem with having a fixed plant is volume. Because the 2514MF is easily relocated, it can work across multiple sites roadsonline.com.au

TECHNOLOGY & EQUIPMENT

producing the required volumes at each location. For producers, that flexibility means a much better financial return on their investment,” Boil explains. This control over processing capacity becomes more critical when considering the nature of recycled asphalt, Boil adds. “With RAP material, particularly in summer, if you process and screen the asphalt-coated aggregate and store it outdoors, it can harden due to heat and a crust forms on the outside. To avoid creating a lumped stockpile, producers need just enough material processed so they don’t run out, but not so much that they have to re-process it. The ProSizer 2514MF gives them that control.” With the ProSizer, the reclaimed asphalt is put through an optimum amount of impact to break the asphalt matrix, leaving the asphalt coating on the aggregate intact. This in turn reduces the need for introducing virgin asphalt to the mix, ensuring the recycled material delivers maximum value, Gordon explains. “When you dig up road material, there’s a lot of variable materials present. The goal for us in designing the ProSizer has been to maximise the quality of the recycled material, by retaining the asphalt component as binder, and also by removing unwanted components such as metal and geofabrics from the mix.” As well as benefits in efficiency and transportability, the ProSizer 2514MF delivers other features in terms of efficiency, ease of maintenance and environmental impact. PROSIZER 2514MF BENEFITS The first design change is the rotated feed bin. On the new model, the feeder bin has been rotated 90-degrees. This means the feeder retains the same five cubic metres capacity while the overall length of the bin and the conveyor is reduced by about two metres. Replacing the standard, high frequency screen with a 2514 multi-frequency inclined screen – which is where the model also takes its name

The Astec Prosizer 2514MF is designed and built for Australian conditions.

from – is another key innovation. Gordon says the new screen design also saved on overall length. “The original plant had a high frequency screen where we exited the screen media by introducing a vibration. But for that vibration to happen, the box had to be at a very steep 43-degree angle so gravity would cause the material to run down. By lowering the discharge point, we were able to reduce the conveyor’s angle to 22 degrees which, in turn, helped reduce the gap between the screen and the feeder. “Also, in the multi-frequency model, the whole screen box is moving, and we have introduced another vibration into the bottom deck,” he says. In addition, the preferred screen media is stainless steel to minimise adhesion between warm asphalt and the screen media surface. “When you are crushing and processing asphalt, it gets warm and as a result it gets tacky and sticky. By introducing the extra vibration, and also using stainless-steel screen media, which has very low coefficient of friction, asphalt-coated aggregates can slide through more easily.” The 2514MF ProSizer is also better equipped to filter out unwanted material such as geofabrics and metal particles from the recycled material, Gordon explains. “A lot of the roads that were spray sealed in the 70s and the 80s have a layer of geofabric to improve adhesion between the road base

At almost three metres shorter in overall length, the Astec Prosizer 2514MF is easily transported across all Australian states.

and the sprayed seal. That’s good for the road, but not so much for the recycling. We have added a hydraulic valve, which can also be controlled remotely as an option. The valve can move the returns conveyor away from the closed circuit, discharging the geofabric and petromatt out of the system and into a bin,” he says. “Also, when you recycle roads, there are always steel wires and cast-iron bits and pieces that get mixed into it. No crusher likes steel going through it. That’s where the selfcleaning magnet on the conveyor comes in and helps get rid of the unwanted material.” The new Astec ProSizer features a Cummins Tier IV diesel/hydraulic engine – an upgrade on the previously Tier III engine – resulting in reduced emissions from the plant. From a maintenance perspective, the addition of an auto-greasing system for all lube points, and a radiator pre-filter system to minimise build-up on the cooling system, helps keep maintenance down. Also, the radiator package has been designed so it can be swung open perpendicular to the chassis for easier access to the engine and more convenient cleaning of the radiators. Gordon says the first Astec 2514MF ProSizer has arrived in Australia, and he sees scope for the new model to be adopted in other countries such as in New Zealand, which has similar road conditions to Australia. “If you have a machine that helps you maximise your recycling and screening output, minimise use of virgin material for asphalt production, reduce emissions and also saves on disposal costs, that’s a win-win-win-win scenario,” he says. “We are very proud of the work done by the Astec Australia team in incorporating feedback from our clients and working in close collaboration with the global manufacturing team. With the compact design of the mobile screening plant, the unit can fit into a single-load trailer and be easily moved around anywhere in Australia, with the result being greater efficiencies and economic outcomes for our clients.”

Caterpillar will introduce a new product update for its large asphalt range in April.

CATERPILLAR: KEEPING MACHINES UP TO DATE

CATERPILLAR IN AUSTRALIA IS SET TO LAUNCH AN ANNUAL PRODUCT UPDATE FOR ITS LARGE ASPHALT PAVER RANGE. ROADS & INFRASTRUCTURE SPEAKS TO INDUSTRY TERRITORY MANAGER CHRIS POWELL REVEALS SOME OF THE NEW FEATURES AND CHANGES.

aterpillar has had an impactful presence within Australia. The company’s product line, consisting of more than 300 machines, is constantly being modernised to fit the current needs of the industry. As part of this modernisation, Caterpillar will soon release its annual product update (APU) for its large asphalt paver machinery range. As Caterpillar’s Industry Territory Manager Chris Powell explains, the APU supports timely release of the feature updates. “The APU allows us to make product updates and improvements, incorporating 68

customer and industry feedback to sustain the quality of Cat products,” he says. The APU process, provides a “bundled” approach to updates, which can include improvements to the technical capabilities of the machine, or other functionality changes, Powell explains. He says that direct feedback from customers has led to changes within the large asphalt paver range, including to the configuration of the machines themselves. “A good example would be the changes made to the screed pendant control, which enhanced the user friendliness by adding additional one-touch functionality

requested by customers,” Powell says. “In the past, we would have had to wait until the next large-scale release of the paver to make that change. Now, we can incorporate that customer feedback in our design a lot quicker.” THE NEW FEATURES A major product update for the large asphalt paver fleet, Powell explains, are changes made to the front-mount screed. Caterpillar is transitioning from using the support of manufacturers, which supplied front mount screeds on our Cat paver range. Instead, Caterpillar

TECHNOLOGY & EQUIPMENT

will now manufacture the front mount screeds internally. Powell says the change will provide benefits to customers. “The main reason we are doing this is for our customers, as it will be a Caton-Cat solution for both the tractor and the screed,” Powell says. “This means that aspects such as warranty, parts and servicing is all integrated within the Caterpillar system. This will provide some great overall benefits for Caterpillar customers following this update.” OPTIONAL FEATURES Also, included in the updates will be optional technology features, aimed at increasing efficiency and ease of use for the large asphalt paver range. “On the technology side, the update will see the introduction of thermal mapping to the large paver range. This option allows operators to map the thermal profile of the asphalt that they are laying. This allows them to assess thermal homogeneity, identify any cold spots and record that information for processing,” Powell says. Another added feature will be the ‘pave start assist’, which enables operators to save their current settings, depending on the type of

application they are working in. This allows adjustments to the implements on the paver, such as the tow point cylinders and the height of the auger to carry over multiple days of operation. “For example, if the operator is working in a car park or a local road, they can save those settings for the next day of operation,” Powell says. “This can make it easier for the operator to return to work the next day, restore the settings, and lay a consistent mat.”

Among other changes being introduced are adjustments to the hopper design to help reduce the frequency of spillages, as well as some general style changes. Powell says all new equipment will have the APU features available as standard, following the updates’ release this year. “The APU is set to release in April. Any new 8-foot (AP600/655) or 10foot (AP1000/1055) paver will receive these updates straight from the factory,” Powell says.

Caterpillar uses annual product updates to improve and update its machinery range.

Dynapac’s CC900e vibratory roller can be fully recharged in approximately 90 minutes.

ZERO EMISSION

IN ACTION

DYNAPAC IS BACKING UP ITS COMMITMENT TO SUSTAINABILITY, WITH THE INTRODUCTION OF A NEW ALTERNATIVE POWERED PRODUCT PLATFORM. The ‘Z.ERA’ program will support the development of more electric powered Dynapac machinery.

ROADS APRIL 2022

ompaction equipment manufacturer Dynapac has an existing pledge to build environmentally friendly machinery. With products housing reduced fuel consumption and features such as ecomode, the company has shown its efforts towards creating a sustainable future in the compaction industry. On World Environmental Day on June 5 last year, Dynapac officially launched its ‘Z.ERA’ program, a long-term initiative to design and manufacture environmentally friendly products. Under the program, Dynapac began to develop alternative power solutions. This development has been an on-going process for more than a decade, Chris Parkin, National Product Manager at Dynapac CEA says.

According to Parkin, momentum within the industry and advancements in technology have created an ideal environment for the introduction of electric-powered products. “There is a drive within our industry, and in the wider population globally, to look at sustainability and what can be done to reduce [greenhouse gas] emissions,” he says. “Moving toward more sustainable fuel options is the direction which many manufacturers are taking. Obviously, one of those options is to become fully electric.” THE FIRST ELECTRIC ROLLER IS BORN The first steps towards an emission-free product were taken by Dynapac almost ten years ago, when the company designed a prototype for an electric roller. Unfortunately this machine was before its time and was not

TECHNOLOGY & EQUIPMENT

widely accepted by the market, This prototype has laid the groundwork for what would become the CC900e today, an electric tandem roller that produces zero emissions during operation. As one of the first products released under the ‘Z.ERA’ program, the CC900e substitutes the conventional diesel engine with an electric battery pack, which powers an electric motor. Importantly, the switch to electrical power doesn’t compromise performance, as Parkin explains. “Operators can be assured that the electric variant is not a complete redesign of the machine. It still has the same well known and trusted basic architecture, just with the diesel engine removed,” he says. “The machine still has the same hydraulic functions and the same compaction output. We are just using an electric motor instead of the conventional diesel engine to drive the hydraulic systems.” The CC900e also provides a quieter machine. This, combined with the lack of exhaust and emissions, allows it to be used in other previously inaccessible areas such as indoors and confined spaces. Another important aspect for rollers of this size is that they tend to work in urban areas, where recharging infrastructure is readily accessible. The CC900e can be recharged in approximately 90 minutes with a fast charger, making the machine ready for a full 10-hour shift of stop and start operation. This allows the operator to use the roller for a full day of operation and charge the machine overnight. Parkin also notes that since rollers of this size are often left idle while asphalt is being raked and finessed after placement, the electric configuration removes the environmental impact of an idle diesel-powered machine and the associated fuel costs. Acknowledging that any innovation often faces some initial hesitation, Parkin says that proving the effectiveness of electric machinery will be an essential step to wider acceptance from the industry. “The industry needs to be shown that a product such as the CC900e can match or even exceed the output and capacity of diesel machines, while being financially viable and remaining operational for a long time,” he says. He notes that switching to electrical machinery also removes the need for conventional maintenance associated with diesel engines. “The electric component removes the need

From a daily maintenance point of view, it will save the operator time checking critical engine items. It will also reduce the associated costs, such as for engine oil changes and filters,” he says. “Regular maintenance, such as preserving the full hydraulics system of the roller, will still be required.” Parkin adds that Dynapac customers can always select a diesel-powered machine, depending on their preference. For example, the CC900 is also available with diesel engine packages that can satisfy stage III, stage IV and recently, stage V European engine emission standards. “For the Dynapac range, we are also able to bring in the latest generation of diesel engines

for operators who wish to stay with the conventional motor setup,” he says. The CC900e is already in production, but Parkin says global manufacturing has seen some impacts from the COVID-19 pandemic. As such, the CC900e is expected to enter wider production by 2023. Dynapac is also preparing to bring more sustainable products to the market in the near future as part of the ‘Z.ERA’ program, Parkin says. “Dynapac is one of the largest global manufacturers of compaction machinery, so we need to stay attuned with the way the world is moving. It is about playing our role as a member of the wider construction manufacturing industry to improve the world we live in,” he says. roadsonline.com.au

TECHNOLOGY INNOVATIONS

FOR TOMORROW DEAN GAEDTKE, KOMATSU’S EXECUTIVE MANAGER FOR CONSTRUCTION, LOOKS AT SOME OF THE COMPANY’S TECHNOLOGY INNOVATIONS AND THE ROLE THESE TECHNOLOGIES PLAY IN MOVING TOWARDS A NET ZERO FUTURE. Komatsu’s hybrid excavators combine diesel and electric power.

s the world moves towards net zero emissions, the construction and resources industries will be expected – and are looking – to play their part in using equipment and technology that deliver carbon-neutral operations. Contractors, project managers, client organisations, quarries, miners and the broader community are all seeking technological innovations and solutions that can help achieve what is essential for the future of the planet. Komatsu is part of many of these innovations which are driving the construction, operation and management of infrastructure and resources projects today, and into the future. Komatsu’s SmartConstruction suite of integrated project management solutions, including intelligent Machine Control (iMC) technology, the Komtrax remote monitoring offerings, and Komatsu’s autonomous haulage solutions, are all examples of such innovations. 72

ROADS APRIL 2022

In moving towards a more sustainable future, Komatsu is leading the way in low emissions engine technology, as well as in moving towards zero emissions technology via an all-electric future. SMARTCONSTRUCTION SmartConstruction is a major step forward in improving productivity and safety in the construction, quarrying and mining industries through the application of unique technology and integrated products. It covers critical steps in a project’s development, from initial site survey and design, through to machine control, machine and project management, machine interconnectivity, review of project progress throughout the construction phase, and finally development of detailed as-built information for future construction and infrastructure maintenance. As Dean Gaedtke, Komatsu’s Executive Manager for Construction explains, Komatsu’s SmartConstruction solution is designed

to work across mixed-brand equipment fleets, offering a “one-stop-shop” service and support solution across all phases of a project’s lifecycle. “With SmartConstruction, the technology around fleet productivity management is exciting, with its ability to save customers a lot of time, money and cost per tonne, while helping monitor safety on every machine in a fleet,” he says. “Site and fleet management teams can watch every piece of machinery in near real-time and see where any hazards may be. At a detail level, they can monitor critical factors such as truck payloads for over and under-loads, as well as issues such as site inefficiencies, over-revving, over-speeds, excess idle times and more.” INTELLIGENT MACHINE CONTROL Komatsu’s iMC technology delivers major productivity, efficiency and cost saving advantages to the company’s ‘intelligent’ range of dozers and excavators, as Gaedtke explains.

TECHNOLOGY & EQUIPMENT

“On bulldozers, our fully integrated machine control systems automatically control blade elevation and tilt according to target design data, allowing our iMC dozers to be used at all stages of a project, from initial bulk dozing, to precision final finish work,” he says. “On excavators, iMC lets operators focus on moving material efficiently, without having to worry about digging too deep or damaging the target surface.” According to Gaedtke, this technology can result in more than a 60 per cent improvement in work efficiency compared with conventional construction processes. “Our latest iteration, iMC 2.0, significantly enhances iMC dozer operations on slopes, while new-generation iMC excavator hydraulics include an automated tilt function, making them ideal for precise and complex batter and slope works,” he says. AUTONOMOUS AND SEMI-AUTONOMOUS OPERATIONS Technologies such as iMC are just one step towards automating the construction sites of the future – and driving safer, more efficient site operations. Gaedtke says Komatsu’s automated technology – already proven in the mining industry – will soon be making its way into smaller-scale operations such as construction and quarrying projects. In the mining sector, Komatsu now has 400 semi-autonomous dump trucks globally driving without operators. “Production is higher and maintenance costs are lower because autonomous trucks are driven exactly as they were designed to be operated. Even tyre costs are up to 40 per cent less due to reduced wear and tear,” says Gaedtke. “In the near future, we will see semiautonomous and autonomous machines expand into our construction and quarry equipment products as the technology becomes more affordable and scalable.” KOMTRAX Komtrax is Komatsu’s remote monitoring system, which the company supplies free of charge with all new and Komatsu Premium Used equipment sold in Australia, New Zealand and New Caledonia. “Our Komtrax remote machine monitoring system gives us and our customers the ability to identify potential issues with a machine, well in advance of them causing a breakdown, so they can be rectified and repaired in a timely manner,” says Gaedtke.

“PRODUCTION IS HIGHER AND MAINTENANCE COSTS ARE LOWER BECAUSE AUTONOMOUS TRUCKS ARE DRIVEN EXACTLY AS THEY WERE DESIGNED TO BE OPERATED.” Since it was introduced in late 2008, Komtrax now covers more than 20,000 machines. “Komtrax has evolved into an efficient, easy-to-use system, that is invaluable for Komatsu in assisting our customers, as well as helping our customers better manage their investments,” says Gaedtke. “[Using Komtrax] we can see how a machine performs, how operators use it, and even benchmark it against other machines. That’s valuable for customers, allowing them to better understand how they can operate the machine more efficiently.” Komatsu’s customers and their operators are using Komtrax to not only identify and fix potential issues before they become problems, but also to improve machine and site performance and productivity, and even operator skills. The latest versions of Komtrax identifies individual operators on a given machine, allowing site or project management and operators to work together closely to improve and develop skills and production levels.

ULTRA-LOW EMISSIONS DIESEL TECHNOLOGY Komatsu now offers a full range of Tier 4 Final-compliant machines across its construction equipment range. “Our new technology engines deliver fuel savings of between five per cent and 15 per cent while complying with Tier 4 Final emissions standards,” says Gaedtke. “These slash diesel emissions and a machine’s carbon footprint, while at the same time giving outstanding performance, efficiency and reliability.” Compared with previous generation Tier 3 engines, Komatsu’s new technology engines reduce both particulate matter (PM) and nitrous oxide (NOx) levels by 90 per cent. Gaedtke says Komatsu’s Tier 4 Final engine technology is proving its benefits on major underground tunnelling projects, where the company’s products have been very successful. “Komatsu machines equipped with Tier 4 engines are delivering significantly lower emissions in confined underground work sites, resulting in far cleaner working conditions,” he says. “Emissions levels from these Tier 4 Final machines are much lower than a previous generation Tier 3 machine, by utilising Komatsu’s advanced engine controllers, new turbo design, exhaust aftertreatment and a catalytic converter.”

Komatsu now has 400 semi-autonomous dump trucks globally driving without operators.

Komatsu’s ‘power-agnostic’ prototype haul trucks could be powered by a mix of diesel, hybrid, electricity or hydrogen energy throughout their lifecycle.

HYBRID EXCAVATOR TECHNOLOGY As a step on the road to net zero, Komatsu has also developed fuel-efficient hybrid excavators that combine diesel and electric power. Gaedtke says fuel consumption on a hybrid excavator is as much as 40 per cent lower than a same-sized conventional Komatsu excavator, saving owners fuel, carbon emissions and operating costs – while still maintaining reliability and production standards. “Komatsu hybrid excavators are based around an ‘Ultra-Capacitor’ linked to the swing circuit to generate power during operation. This has shown itself to be safe and reliable across millions of hours of operations around the world.” GOING FULLY ELECTRIC Fully electric machinery has traditionally not been commercially viable for construction sites or quarries – especially in higher horsepower machines. Will we see this happening in the future? Gaedtke is positive. “The technology will be developed, proven, and then needs to be made commercially viable, initially for smaller horse-powered machines,” he notes. 74

ROADS APRIL 2022

“An example of this is our all-electric prototype three-tonne mini excavator, which is powered by a lithium-ion battery, and uses electrics instead of hydraulics for the arm, boom, bucket, swing and travel functions. The prototype is currently on display at Komatsu’s new Innovation Hub in Wacol, Brisbane, and is a pointer to how this technology will develop. What we are likely to see far sooner, however, is power source blends – diesel and electric battery, hydrogen power systems, and kinetic energy systems, Gaedtke says. “The major challenge for many equipment operators will be how they phase out existing machines, while adapting to net zero and running sustainable businesses – and at the same time remaining profitable,” he observes. “Take the case of an operator with 200 machines in a fleet across the country. If they wanted to reduce their greenhouse gas emissions by a significant amount, they would have to replace a large percentage of their fleet. How do they do that?” One way to do this, he notes, is through a new concept that Komatsu has been active in, known as ‘agnostic technology.’ It’s an option that particularly applies to haul trucks,

L O I P

whether rigid or articulated. “This is based around the principle of designing trucks that can be powered by diesel, hybrid, electricity (trolley or battery) or hydrogen. Throughout a truck’s operating life – which typically extends through multiple engine rebuilds/repowers – it may be powered by a mix of these alternatives,” he explains. A key part of meeting greenhouse gas reduction targets will be staged replacement of fleet with lower emitting machines, while operating current machines to achieve optimum efficiency. “This is where Komatsu can really add value for our customers through our integrated offerings of technology solutions.” Gaedtke says competition between original equipment manufacturers to devise these solutions would also be a strong driver of major technology improvements. “Certainly, our customers are driving us hard to devise zero carbon power systems in our products as fast as we can. This is something in which we all – manufacturers, end users, clients, governments and communities – need to play our part as we develop our roadmap to net zero emissions.”

hile compacting road shoulders and ditches, operators can at times be obligated to work on hazardous slopes which force them and the machine to be in a tipping position, with no alternative options available. Road Widener’s patented Offset Vibratory Roller attachment aims to prevent these situations, which can lead to serious harm, or in some cases, fatalities. The innovative attachment relocates the drum to a remotecontrolled offset arm that can be attached to almost any grader, compact track loader, wheel loader or skid steer. The Offset

Vibratory Roller allows the host machine to remain safely on a flat surface while compacting road shoulders and ditches. Based in the United States, Road Widener is firmly entrenched in the road construction industry globally. Founded by two road construction professionals, the company has more than 30 years of industry experience. As Todd Granger, Road Widener’s Director of Sales, explains, the industry’s desire for safer compaction attachments led to the creation of the Offset Vibratory Roller. “The concept of the attachment started in early 2010, with a couple of designs options,”

Granger says. “Over time, we added and subtracted some features. We were issued an Australian patent in August 2019. In this same year, we were recognised for the safety capability and the innovation of our machine through numerous awards, including the 2019 Equipment Today Top 50 Contractors’ New Product award. The product was then launched globally in 2020.” Granger says the attachment provides an alternative to conventional machinery to prevent accidents, of which he has witnessed many first-hand. “By using the offset arm, it allows the

operators to keep their host machine on a hard surface and then compact the shoulders with a variety of material types. This would be challenging for a double-drum roller,” he says. “These applications can include difficult, uneven terrain, such as creek beds and steep road shoulders. For any project which offers a safety challenge, we have created an ideal solution in the form of a vibratory compaction unit.” The Offset Vibratory Roller offers a wide range of motions, with the attachments arm able to swing more than 150-degrees, as well as offering trench compaction by allowing operators to access 30 inches (76 centimetres) below grade. ATTACHMENT FEATURES Granger says the Offset Vibratory Roller also provides the user with optimal control and accuracy, due to the attachment’s remote operation and reduced weight. “Thanks to the remote control, all of the functions, from swinging the boom to twisting the roller or turning the device on or off, are controlled from the cabin,” he says. “It also doesn’t have an onboard engine, which helps cut down on maintenance and reduces the size and weight of the attachment.” Initial industry feedback has also led to increasing the capabilities of the machine to support asphalt compaction, Granger says. “The Offset Vibratory Roller was designed to compact aggregate initially. But our customers told us that because they were laying down asphalt, they required a machine to compact that as well,” he says. “Hot asphalt, of course, adheres to drums. So we developed a spray bar kit for the roller, which sprays water on the drum to prevent the asphalt from sticking to the surface.” Three interchangeable drum sizes are available for the Offset Vibratory Roller,

The Offset Vibratory Roller attachment can be used with any brand of host machine.

SO, IT SUPPORTS THEIR FLEET’S FLEXIBILITY SIGNIFICANTLY.” which come in thicknesses of two, three and four inches. The attachment supports up to 30-degree drum pivot, allowing for smooth operation on sloped surfaces. All of the Offset Vibratory Roller’s features combine to provide an attachment suitable not only for road shouldering, but also for compacting topsoil, crushed stone, gravel, recycled materials and even limestone. CREATING A GLOBAL PRODUCT One of the unique features of the Offset Vibratory Roller, according to Granger, is its versatility. The product can be attached to any piece of machinery which has a standard skid steer hook up plate, flat face hydraulic couplings and a 12-volt power capacity. This allows the attachment to be used alongside skid steers, compact track loaders, loaders and road graders of any brand or make. The attachment also comes without an on-board engine and can work with standard and high-flow hydraulics. Granger shares that its universal design can

help operators save on costs by removing the need to purchase purpose-built machinery. “The product allows operators to use prime movers they already have in their fleet, as opposed to having to purchase an additional piece of machinery which has an on-board engine. So, it supports their fleet’s flexibility significantly,” he says. “It is a very universal attachment and a global product. Without an onboard engine, we aren’t required to build different models and variants to suit different customers around the world. This also allows the machine to operate with ease within countries and regions that have strict emission reduction rules for machinery.” The Road Widener product has already proven to be effective in North America. “We are currently expanding our footprint in the European union, which is a big focus for us in providing an enhanced safety product,” Granger says. “We also have models coming across the channel for Australian contractors as we speak.” roadsonline.com.au

CUSTOM-DESIGNED MACHINERY, MADE FOR

AUSTRALIAN ROADS MATTHEWS BROTHERS ENGINEERING’S CUSTOM-BUILT MACHINERY HAS SERVICED THE AUSTRALIAN ROADMAKING INDUSTRY FOR OVER A CENTURY. AS OWNER PAUL MATTHEWS TELLS ROADS & INFRASTRUCTURE, THE BUSINESS CONTINUES TO BE AN INNOVATOR IN THE MARKET.

s a third-generation family owner of Matthews Brothers Engineering (MBE), Paul Matthews is proud of his family’s legacy of producing affordable and durable road making machinery. This commitment was highlighted last year as the company celebrated its centenary. Founded by Vic Bradley and Roy Matthews in 1921, MBE was a key supplier of bitumen spraying gear and bitumen kettles to the Victorian Country Roads Board during the peak road-building era in the early 20th century. Over the years, the company has built a reputation for manufacturing affordable and highly customised roadmaking equipment, including bitumen sprayers, dog trailers, melting tanks, spreader boxes and multipurpose asphalt vehicles. MBE’s bitumen sprayer units fit on existing truck chassis and are made to order as per the requirements of each client. The sprayers, which are manufactured in-house by MBE at its workshop in Altona North in Melbourne, feature an optional Guaranteed Target Application Rate, or G-TAR system, that helps operators achieve precision and consistency in bitumen application. “Over the years, we have grown from making small trailer-mounted bitumen sprayers to manufacturing 14,000 litre, twin-bar bitumen spraying units with all the bells and whistles. Our products are known for their reliability and the fact they are specifically designed for Australian conditions,” says Matthews. Today, MBE continues to grow its equipment offerings, with its bespoke bitumen tankers and spray sealing equipment forming the cornerstone of the company’s product range. MBE designs a range of bitumen sprayers, 78

including models with 4000, 6000, 10,000 and 14,000 litre tank sizes, all of which are built to comply with Australian Standards and the Transport of Dangerous Goods Act. Matthews says feedback from clients have contributed to safety and efficiency improvements to the classic bitumen sprayer model. “MBE has created a sprayer automation system called G-TAR. This is a computerised spraying control system with spraying tables built in and intuitive operation of the touchscreen allowing for simplified spray bar operation leading to less manual handling and achieving consistency of application rates,” he says. “In 2001, MBE introduced OZIBAR, a premium spray bar system specifically built for Australia’s challenging and wide-ranging conditions. All of these improvements have resulted in a safer

and more efficient equipment.” Feedback from operators has also influenced many safety improvements, some of which were previously optional, to be installed as standard on the classic bitumen sprayer model. This includes provision for safety showers and a pressure shutdown system. MORE THAN MEETS THE EYE Just like its bitumen sprayer, MBE offers a classic model for its range of dog trailers. Available in 14,000, 19,000, 20,000 and 25,000 litre tank sizes, the dog trailers also provide two, three or four axle configurations. This allows operators to customise the trailer to suit their needs. Whether this be a simple mobile storage unit, or to power integrated bitumen pump agitators. All MBE dog trailers also feature air suspension and multi voltage anti-lock braking and electronic braking systems.

TECHNOLOGY & EQUIPMENT

Matthews says that operators will notice similarities between the company’s bitumen sprayer and dog trailer models. “Our piping and burner system design is duplicated on both the bitumen sprayer and the dog trailer, so operators can feel a sense of familiarity when operating either machine,” he says. For a more versatile design, MBE also designs and manufactures multi-purpose asphalt vehicles (MPAV’s). “All MPAVs are custom-built to each client’s specification. There is no ‘classic build’ here. MPAVs are essentially utility vehicles that go onsite with spraying crews and each company has their own template for what their crews need,” Matthews says. These setups can support a range of attachments. “They can be made up of small emulsion tanks with spray bars and include intermediate bulk containers, hose and reels, toilets, tool and equipment storage, generators and even small cranes,” Matthews says. FOR INTRICATE APPLICATIONS MBE also designs machinery which is suitable for smaller repair jobs, such as bitumen melting tanks. The bitumen melting tanks are available in 500 and 2000 litre variants. They are both self-contained and skid mounted, with the subframe of the product allowing it to be used with a third-party machine, such as a truck or a trailer. As Matthews explains, the bitumen melting tank is complementary to MBE’s wider machinery range, which is suited for larger projects. “It’s designed to allow clients to undertake small sealing repairs which don’t require a full spraying unit. They can be transported easily

to site on the back of a flat bed,” he says. MBE’s innovations for affordable and convenient roadmaking equipment do not stop there. The company has also designed a product which removes a serious headache for contractors and operators alike. MBE’s rear spreader box units come in two varieties. One is ‘fixed’ and allows for a 2.7-metre spreader width. The other is an innovative ‘winged’ design which is 2.5- metres wide for transit purpose, but pneumatically extends to 2.9 metres during operation. Matthews says the winged model was designed to address an issue many operators struggle with. “The fixed width spreader box unit is often wider than the back end of the tipper truck they are installed on. As such, companies need to apply for oversize permits for travel and use,” he says. “With the winged version of our spreader box, the body of the spreader box has the same width as the back end of the tipper truck. The winged sections only expand when in operation. Therefore, no oversize permits are required.” VERSATILE SUPPORT Matthews adds that customers receive fit-for-purpose machines from MBE, thanks to the manufacturer’s ability to

customise equipment. “For example, while we recommend the use of Scania’s Chassis range for our sprayer units, our team has also successfully built our sprayers on Mercedes Benz, MAN, Volvo, Hino and Izusu chassis,” he says. For additional versatility, Matthews says MBE’s products can be used along machinery from other providers. “The advantage of buying all equipment from MBE is we become a one-stop-shop for technical support and servicing,” he says. “Many of our components are manufactured in-house, which assist us in avoiding supply chain issues. We can supply our clients with replacement bitumen pumps, plug cock valves, wedge gate valves and spray bar valves. We also have the capacity to make bespoke parts to order. Many of our spare parts are interchangeable between models.” With a strong legacy to follow, Matthews says the company will keep on innovating and enhancing its product portfolio. “We are always looking at areas to expand and develop ideas for our clients. MBE doesn’t offer a set product with no variations. Every unit that leaves our production workshop is different to the units before it and units after it. Our clients are provided with quotes that include an extensive list of optional extras and chassis options to build the perfect unit for their specific needs.”

THE SECRET

TO PAVEMENT LONGEVITY IN THE PURSUIT FOR DURABLE PAVEMENTS THAT CONTRIBUTE TO BROADER SUSTAINABILITY, COFFEY TESTING SPECIALISTS CAMERON BIK AND RUSSELL BOOTH BELIEVE MATERIAL TESTING IS AN IMPORTANT, BUT UNDERESTIMATED, PIECE OF THE PUZZLE.

he adage ‘proper preparation prevents poor performance’ is certainly relevant to pavement construction, where future savings and, more importantly, safety of commuters, rely on satisfactory performance of pavements. As an experienced pavement specialist, Cameron Bik, Coffey Testing’s General Manager for New South Wales and the Australian Capital Territory, has seen his share of pavements failing prematurely, where adequate investigation and testing could be a game-changer. “Once a section of pavement is laid, it’s a very costly exercise to make any variations or improvements if design factors were assumed incorrectly in the first place. It’s also highly inconvenient to divert the traffic

for a do-over if the original pavement fails prematurely. For these reasons, the best way to ensure durable pavements is to test the parameters correctly from the get-go,” he says. As one of Australia’s industry leaders for material testing, Coffey Testing’s expert teams are often involved in pavement investigation, stabilisation trial mix design and conformance testing, deflection monitoring, material quality and conformance testing and compaction testing across all scales of pavement projects, from remote rural backroads to major distributors. Coffey Testing’s network of NATA accredited base laboratories and associated annex laboratories assist clients to gain an in-depth understanding of ground conditions

and soil composition for their projects, which enables them with better planning and construction, as well as mitigating potential risks. “Soil investigations are very much reliant on skills and experience. There are, of course, guidelines as to how many samples are required to be taken. But, if you don’t send experienced people to the site, you might miss a defect or get samples that are not homogeneous or cannot be interpreted correctly, so it does not yield the desired results,” says Bik. Bik says through his years of experience, he has come to ascertain that the secret to pavement longevity is thorough testing. “The more we know about a pavement prior to construction, the better the risks

are controlled. By increasing the amount of investigation and associated laboratory testing, we reduce the risks of missing key areas and materials within the pavement, which may come to fore at the time of construction, or worse, six weeks after the road is finished,” he says. “By undertaking testing, not only can we test a vast array of properties within the pavement’s materials, but we can also undertake investigation and trials to ensure the material properties meet the design option. This is critical because if these properties aren’t met, the pavement will fail prematurely.” TESTING FOR ROAD REHABILITATION Apart from pavement construction projects, there’s one more area where material testing becomes critical to sustainability and longevity of pavements, and that is in pavement rehabilitation projects. As Russell Booth, Coffey Testing’s Sydney Laboratory Manager observes, initiatives from local councils to rehabilitate existing pavements and re-use the material are on the rise across every state. Particularly, he says, use of foamed bitumen technique has been gaining more popularity. “In-situ stabilisation design, particularly foamed bitumen is being used more. Pavement design software is now allowing for these to be modelled more easily in the latest version due to the versatility, reduced impacts to the environment, reduction in waste and time savings on completing projects which benefit the community,” he says.

Coffey Testing’s Senior Technician David Doran performing the set up of a density bias for pavement materials in accordance with TMR methods.

“The design guidelines around these pavements are becoming more relevant on a local government area (LGA) level, meaning their yearly budgets are stretching further. There has also been a strong emphasis around recycled materials in terms of recycled crushed concretes for roadbases, selected material zones (SMZs) and crushed glass for drainage materials,” he adds. Booth says Coffey Testing has a strong presence in this area as well. Currently, Coffey Testing is the only private testing laboratory network in Australia equipped with the specialised WLB10S Foaming Trial Machine for foamed bitumen modulus testing. “Coffey Testing is a member of

AustStab – Australia’s pavement recycling and stabilisation association. We have members within the AustStab Technical Working Group, who are constantly discussing innovations, improving guidelines, and troubleshooting industry issues,” he explains. “We have also moved into the trial mix design for foamed bitumen pavements. Our team can trial various percentages of binders and secondary binders to ensure the appropriate design modulus is met.” These trials, Bik explains, can lead to significant cost savings on rehabilitation projects. “For example, we might do a trial mix with a certain percentage of bitumen, and it might be overdosed. We can then do another test and reduce that bitumen content by, say, one per cent,” he says. “Now, bitumen in a rehabilitation project counts for roughly about 30 per cent of the cost. So, if we can reduce that bitumen content by any small percentage, there’s huge savings to be made for the contractor. We then do more testing during construction to prove that the stabilised road section did meet the required strength.” Given the benefits of conducting thorough material testing and trials, both for construction of fresh pavements and rehabilitation of existing ones, Bik’s message to contractors and asset owners is to not be afraid of ordering additional tests. “Lack of investigation and testing is like crossing a busy highway with your eyes closed. You might make it to the other side, but why take the risk?” roadsonline.com.au

VEGA’s level measurement sensors are installed at Fulton Hogan’s Eastern Creek asphalt plant in New South Wales.

BEHIND FULTON HOGAN’S

‘LEVELLED’ ASPHALT PRODUCTION

VEGA’S RANGE OF NON-CONTACT RADAR LEVEL TRANSMITTERS AND PRESSURE TRANSMITTERS HAVE SPELLED SAFETY AND RELIABILITY FOR FULTON HOGAN’S ASPHALT PLANTS IN AUSTRALIA. MARK WHEATLEY, THE TECHNICAL MANAGER-PRODUCTION AT FULTON HOGAN INFRASTRUCTURE SERVICES IN NEW SOUTH WALES, EXPLAINS WHY.

s Technical Manager-Production for infrastructure construction company Fulton Hogan, Mark Wheatley oversees asphalt production processes across a number of Fulton Hogan plants in New South Wales. A common element in these plants, apart from the usual hubbub of asphalt production, is the presence of little, yellow-coloured sensors hidden in the – often difficult to access – nooks and crannies of the plant, sending real-time level measurement data to the control and monitoring systems. These sensors, supplied by VEGA Australia, make sure the level of liquid and solid materials that make up the asphalt mix are reliably measured at any given time, so there’s no overfill or over-draw from the tanks. 82

ROADS APRIL 2022

With all the complexity and magnitude of an asphalt production plant, it’s easy to overlook the critical role the humble level transmitter plays in ensuring the plant’s reliability, Wheatley observes. “You may not think a lot about the bitumen road pavement that you drive on, or the bitumen tarmac at airports, but these can be tricky products to manufacture and store. We deal with elevated temperatures in our tanks, fuming product, the existence of potentially flammable gases, and we handle not only liquid materials but also solids such as lime and dust,” he tells Roads & Infrastructure. “We have different bitumen manufacturing plants which, for various reasons, have different approaches to tank level measurement. Some plants were constructed

to measure liquid level via pressure instruments at the bottom of the tank, and some have top-mounted level instruments. We also have tanks of various shapes and sizes. I have found VEGA has the instruments to meet all our level requirements,” he adds. NON-CONTACT LEVEL MEASUREMENT In recent years, advancements in non-contact level measurement with radar technology have made it easier to configure devices that are difficult to reach or located in harsh environments. VEGA, as a sensor manufacturer for high demand industries like mining and transport, has been a frontrunner in this space. While conventional pressure gauges used for level indication were common in the

SAFETY

past, Michael Summersby, Area Manager, VEGA Australia, says many asphalt plants have upgraded to non-contact radar level measurement devices from VEGA. “In many production facilities there are measuring points that are extremely difficult to reach and often located in dangerous places. Climbing into bunded areas or to top of tanks in bad weather with equipment, such as a tablet and adapters, can be a very difficult and dangerous task. Having the reliability of remote access to instrument setups and functions via Bluetooth has real benefits for plant operations,” says Summersby. “Non-contact level measurement with radar is characterised by especially high measurement accuracy. The sensor sends microwave signals towards the medium from above. The surface of the medium reflects the signals back in the direction of the sensor. Using the received microwave signals, the sensor determines the distance to the product surface and calculates the level from it,” he adds. For Fulton Hogan, VEGA’s non-contact radar level transmitters play key functions: they protect the tanks from overfilling, they ensure the heating coils in bitumen tanks remain covered, and they also help keep track of material availability. “Our initial level requirement was for overfill protection,” says Wheatley. “By reliably and accurately measuring the level in our tanks, these instruments can interface with our safety interlock systems so we can avoid overfill and ensure heating coils in the tanks remain covered. The instruments also give us a backup to ensure we have adequate raw materials to meet customer orders and the required tank space to manage raw material deliveries.”

EASE OF MAINTENANCE As a bonus, Wheatley says VEGA’s noncontact level transmitters are easy to setup and maintain. “We have noticed that the lens-type radar level transmitters require little maintenance. They have been reliable, and upon checking, the face of the radar seems to remain unaffected by the atmosphere inside the tank,” he says. “Our electrical contractor likes to familiarise himself with the instruments, because he has to incorporate them into a system which may not only include stop/ start interlocks and status indicating lights but may also include a remote level display for the plant operators or a display at the tanker loading area,” he adds. As Summersby explains, VEGA Australia’s area managers often provide a familiarity training to electrical contractors onsite following an initial visit and offer consultation for product selection. This training is often enough for the contractors to set up and maintain the transmitters themselves. Support is also readily available from VEGA’s service department if the customer prefers. “Our service department, of course, get involved if the installation is a bit tricky, or if the plant would like them to do the commissioning. We also have service contracts with some plants to carry out periodic audits of their VEGA instruments,” he explains. VEGA TOOLS Using the VEGA Tools application, plant operators and technicians can not only measure tank levels precisely in real time, but also adjust the parameters and set up the sensor remotely. All of VEGA’s different

programmable sensors can be managed with the same app, allowing sensors to be parametrised wirelessly via PC, laptop, tablet or a mobile phone. The VEGA Tools app can also be used to for demonstration/familiarisation purposes, even before the instruments are purchased. The simulation function allows plant operators and electricians to check that their system operation and logic is correct, as part of the commissioning process. With certain tanks in asphalt plants containing hazardous and flammable materials, Summersby says VEGA’s area managers are also familiar with instrument certification, allowing them to offer the type of sensors that meet the customers’ certification requirements, such as intrinsic safety or SIL (safety integrity level). “Depending on the nature of the product being measured, asphalt plants may or may not require radar sensors with additional certification and VEGA can accommodate so clients purchase sensors with these options only where necessary. This ensures clients get full value out of their purchase” he explains. Back to Fulton Hogan, Wheatley says, using VEGA transmitters has ensured reliable and accurate level measurement across the company’s asphalt plants. “I have to say, the non-contact radar level transmitters we use from VEGA have come a long way over the years. The instruments we have installed measure the level of different products very reliably, while being suitably certified for hazardous area installations. Our electrical contractor is impressed with how easy it is to set up and maintain the instruments, so it’s a win-win scenario for all of us.”

RESILIENCE STRATEGIES FOR

PLANT OWNERS

ROADS & INFRASTRUCTURE TALKS TO ZURICH RESILIENCE SOLUTIONS’ PRINCIPAL RISK ENGINEER, EVAN BLACKBURN, ON IDENTIFYING AND MITIGATING RISK AREAS FOR HEAVY EQUIPMENT AND MOBILE PLANT OWNERS.

ith 25 years of experience in the insurance industry, including 20 years in risk assessment, Evan Blackburn has a deep knowledge of key risk areas across multiple industries. As the Principal Risk Engineer at Zurich Resilience Solutions, Blackburn specialises in mining insurance risk assessments, advising heavy equipment and mobile plant owners on potential risk areas within the industry, and helping to moderate these risks. When it comes to heavy equipment and 84

ROADS APRIL 2022

mobile plans, Blackburn says a number of risk areas remain dominant in the civil construction industry. Topping that list is natural hazards. As proven by the devastating floods in Queensland and New South Wales in March, natural hazards such as cyclones, floods and fires can pose a serious threat and considerable financial loss to asset owners. Blackburn says that such risks within the civil construction industry can be alleviated by following the correct processes.

“An example would be a site-specific risk assessment to understand natural hazard exposure from flooding, storm water and catchment water and adopting management plans for these hazards. Having trigger action response plans for storm events means a mobile plant can be moved to higher ground to prevent damages,” he says. Similarly, Blackburn says risk engineers can assess the state of equipment maintenance to help asset owners with better fire protection for their stationary and mobile equipment.

RISK MANAGEMENT

Zurich Resilience Solutions addresses a rapidly changing risk landscape with a holistic approach.

Another key area where Blackburn says risks often emerge is related to employee competency and operator training. This also extends to equipment hire and having control over dry hiring. Here, he says, implementing procedures such as safe work method statements – better known as SWMS – can help put in measures to control the risks. Negligence on worksites is an example of a recurring risk for mobile plant owners, with factors such as operators not assessing surroundings, lack of security on site and failure to take adequate precautions potentially ending in financial losses. “These can bring about repair costs, both for the infrastructure and the owner’s equipment, as well as recovery costs for any affected third parties,” Blackburn says. “Add to that the loss of productivity the owner has to endure during the equipment downtime, and suddenly you are seeing huge repercussions resulted from a slight oversight,” he points out.

ZURICH’S APPROACH Providing insurance for small, mid-size, large and multinational companies, the Zurich Group supports a range of insurance services to more than 215 countries and territories globally. Blackburn says the Zurich Resilience Solutions package was created to address risks with a holistic approach, taking into consideration the rapidly changing risk landscape. A key strength of Zurich Insurance, he says, is its wording. “The foundation of the Zurich process is Zurich Resilience Solutions engagement, to undertake a fleet-mobile plant risk assessment to better understand the fleet exposures and controls, therefore helping to identify these risks before they become serious issues,” he says. “Zurich’s policy wording is market leading in the plant and equipment space. Our policy can be specifically tailored to the customer’s needs in terms of structure and coverage with the ability to choose from a range of additional benefits such as downtime, increased cost of working, hire charges, hired in, hired out and more,” he adds. The Zurich Resilience Solutions team is made up of Zurich’s risk engineers, which aim to help companies better manage their exposures. “Our experienced team of risk engineers have deep industry knowledge to help address the risks and exposures for our customers, not only from an equipment perspective, but also from additional areas of risk such as workers’ compensation, public liability, contract works and cyber insurance.” Businesses that present lower exposure areas can also be rewarded as part of Zurich’s package. “There are potential actions that could be taken to reduce risk and they would be identified [by Zurich’s risk engineers] during the mobile plant risk assessment. If the risk grades well, then this will positively impact our exposure pricing, which ultimately could lead to a reduced premium,” Blackburn says. UNDERSTANDING URGENCY Blackburn says that one of the core benefits of early risk mitigation is reducing downtime for operators. For affected customers, Zurich delivers service with a sense of urgency.

Evan Blackburn, Principal Risk Engineer, Zurich Resilience Solutions.

“We understand how important it is for businesses to keep on working, so if an affected client has an item of equipment that requires timely repairs, we can immediately hire a replacement item so they can continue to work,” Blackburn says. “Our customers also have peace of mind knowing that any additional plant items, either owned or hired, are automatically covered under our policy with the ability to use their choice of repairer.” As Blackburn explains, businesses can exponentially reduce their chances of encountering hazards by following some simple tips. “I would advise operators to avoid using labour hire operators where possible, as this introduces greater risk to the business and adds potential for mobile plant losses,” he says. “Also ensure verification of competency (VoC) is strictly enforced for mobile plant operators and establish a best practice process for time-based refresher of VoCs across all of your mobile plant types, not just the high-risk equipment. These controls are even more important if labour hire cannot be avoided.” Irrespective of the degree or type of risks involved, Blackburn says heavy equipment and mobile plant owners can be certain that Zurich’s experienced team will find the right outcome to fit their needs. “At Zurich we deal with many types of plant and equipment exposures, but our primary objective is to deliver a comprehensive and tailored insurance solution for each individual business.” roadsonline.com.au

BUILDING A BRIGHT AND

DIVERSE FUTURE

ROADS & INFRASTRUCTURE SITS DOWN WITH LESLIE CHUNG, DIRECTOR OF DONALD CANT WATTS CORKE NATIONAL INFRASTRUCTURE TEAM, TO DISCUSS HOW THE COMPANY IS SUPPORTING ITS DIVERSE WORKFORCE.

ith a ratio of six to seven female to male employees, the National Infrastructure team within Donald Cant Watts Corke (DCWC) is one of the most diverse professional services teams in the infrastructure industry. As part of an end-to-end project services company with over 50 years’ history, DCWC’s Infrastructure team offers integrated consultancy 86

ROADS APRIL 2022

services on some of the country’s biggest infrastructure projects, from Victoria’s North East Link Project to New South Wales’s Western Sydney Airport and many more across rail, road, aviation, water treatment, dams and marine sectors. When asked how the diversity has benefitted the team, Leslie Chung, Director of DCWC’s National Infrastructure team, says inclusion

of diverse professionals has not only supported the delivery of multi-billiondollar projects, but also helped to foster greater creativity. “I can confidently say that some of our successes have been directly attributed towards our diverse backgrounds. Diverse backgrounds allow different viewpoints to shine. It creates creativity based on cultural differences and that’s what sets us apart,” he says.

DIVERSITY & INCLUSION

“As markets are increasingly becoming more competitive, diversity is what allows new ideas to be formed. These new ideas are what our clients value ultimately in the DCWC brand.” BENEFITS FOR BUSINESS As part of its services, DCWC delivers advice throughout every stage of a project. This includes quantity surveying, project management and associated services. The National Infrastructure team focuses on cost advisory, public-private partnership advisory, constructability, and project delivery management. Chung says that diversity plays a major role in the delivery of these services. “Because of our inclusive and diverse professionals, we have successfully won and delivered multiple billion-dollar projects. As both state and Australian federal government projects shift to prioritise value-aligned contractors, being able to highlight our Local Industry Development Plan (LIDP) and diversity policies and inclusions have made all the difference when tendering for a project,” he says. “This translates to our signature trusted advice and outstanding results, which is ultimately what our clients value most from our team,” he says. Chung adds that providing equal opportunity is a small step in shaping a stronger industry for future industry professionals. “Whilst our industry has come a long way in supporting women in construction, we always believe more can be done. With billions of dollars announced by both state and federal governments for infrastructure projects, I believe we can certainly benefit from increasing [presence of] women with diverse backgrounds in leadership positions,” he says. Such benefits are already being demonstrated by DCWC’s Infrastructure team, which is encouraging its employees to gain experience in senior positions. “To foster and celebrate our diversity of ideas in our people, we include our personnel in rare project leadership positions, juxtaposed against our directors so that they can receive mentorship,” Chung says. “They are always actively finding solutions with our clients, an aspect which our clients love.”

“OUR ORGANISATION IS COMMITTED TO MANY CORPORATE SOCIAL RESPONSIBILITY INITIATIVES, INCLUDING AREAS SUCH AS DIVERSITY, SUSTAINABILITY, COMMUNITY, EDUCATION AND RECONCILIATION.”

ATTRACTING THE RIGHT TALENT Fostering a diverse and inclusive working environment does come with its challenges, Chung says. “There are always challenges. It is one thing to superficially state that a company is fostering diversity, but it requires significant investment to truly live, breathe and be accountable for diversity,” he says. But as Chung explains, the result can open the doors to attracting talented professionals. He says this is especially important, with the infrastructure industry currently struggling with a shortage of skills. “A leader who truly wants to excel and attract the right talent needs to look at their personal values and ask themselves if their team environment is where people would feel safe, supported, and ultimately enjoy working for,” he says. “A lot of companies brag the rights that they are the best company, but what metric is that based on? I truly believe that if companies can sell their values and the ‘why’ to potential candidates, the right talent will come along.”

is committed to many corporate social responsibility initiatives, including areas such as diversity, sustainability, community, education and reconciliation,” Chung says. “Nationally, the company supports a range of community and social centric initiatives, charities and causes each year.” Supporting these causes can all be inspired by supporting internal change first, Chung says. “The construction industry has come a long way towards building a better and brighter future for generations to come, and DCWC is proud to be a part of that. However, we know there is always more to be done,” he says. “Building this future is much easier to do when you have a team of passionate and motivated employees in an organisation that supports this cause.” Leslie Chung, Director of Infrastructure, Donald Cant Watts Corke.

INVESTING IN THE FUTURE DCWC’s commitment to diversity and inclusivity also aligns with the company’s other social responsibility initiatives. DCWC’s Reconciliation Working Group works to further support the national reconciliation movement through the business’s practices.

Many of our customers are now looking at their business practices and how they can offer a more sustainable portfolio of products or redefine the way they operate. [They want to] prepare for future requirements and the industry standards that may take effect in the coming years. Dynapac is making progress to this effect, with an ability to supply power packages from Tier-III up to the latest Stage-V emissions, the launch of design features such as True ECO Mode, Seismic Compaction, Optimised Eccentric Weights and Z.ERA (Zero Emissions Era) and the introduction of CC900e in the electric range of products. As always, safety is at the forefront of any new Dynapac developments. Some examples include the roller cabin with rotating seat for better ergonomics and jobsite visibility, full 255-degree Forward

Facing seat technology, fume extraction to remove dangerous fumes from operator areas, and paver options such as MatTracker – which removes the screed operator from working near live traffic. WHAT DO YOU THINK IS MOST INTERESTING ABOUT THE ROAD CONSTRUCTION INDUSTRY? Getting to know a lot of customers across Australia. Working together with the local CEA sales representatives, it is challenge but also very rewarding to find the right paver for our customers. The best part is the commissioning at the end of the process and to see a perfect paving result, happy customer and crew. HOW HAS BEING A MEMBER OF AFPA BENEFITTED YOU IN THE INDUSTRY? Being a member of AfPA has meant our business and our team have been exposed to healthy discussions and networking opportunities surrounding the best industry practices that benefit the collective flexible pavement industry. Given our involvement, I like to think we bring a level of knowledge to the conversation and, likewise, we gain insights from others within the association sharing their knowledge and experiences with the broader group. The AfPA affiliation allows us to stay closer to not just our customers, but also to the industry and what the market/industry requires in this ever-changing landscape. It also gives us the opportunity to attend social events and partake in Tech Talks and Webinars. WHAT ARE YOUR GOALS FOR THE FUTURE? To help the Dynapac CEA team grow and further establish the Dynapac paver brand in Australia, to help build a team of specialists across the country, and to support our growing customer base.

VICTORIA Mt Derrimut Rd level crossing removal contract awarded Early works have commenced and a construction contract awarded for the Mt Derrimut Road level crossing removal project in western Melbourne. An alliance between McConnell Dowell, Arup, Mott Macdonald, Metro Trains Melbourne, V/Line and the Level Crossing Removal Project has been awarded the contract to deliver the $234 million project. Final designs unveiled for the multi-million-dollar project include a new 1.2-kilometre elevated rail bridge over Mt Derrimut Road to replace the level crossing and a new Deer Park Station. The designs include a new transport hub that features a new train station, a multi-bay bus interchange, landscaped forecourts, and 150 new and upgraded car parking spaces. Major construction activities on the Mt Derrimut Road level crossing removal project are scheduled to begin in mid2022 and completed in 2024. Contract awarded for Melbourne’s Narre Warren-Cranbourne Road A major project to upgrade the Narre Warren-Cranbourne Road in Melbourne’s south-east has moved to the next phase with the award of the construction contract to McConnell Dowell. The project forms part of the $2.27 billion Suburban Roads Upgrade – South Eastern Roads and Northern Roads package, to upgrade suburban roads across the south-eastern and northern parts of Melbourne. The Australian and Victorian governments are contributing $1.1 billion each to the package. The Narre WarrenCranbourne Road upgrade includes

adding an extra lane in each direction between Thompsons Road and the South Gippsland Highway to boost capacity and slash travel times. The upgrade is expected to be completed by 2025. WESTERN AUSTRALIA Contract awarded for new METRONET Midland Station The Midland Junction Alliance – made up of McConnell Dowell Constructors, Georgiou Group, Arcadis Australia, and BG&E – has been awarded a $246.7 million contract to design and construct the new Midland Station in Perth. The contract includes decommissioning and demolishing the existing 53-year-old station. The new station will be located between Helena and Cale streets and will incorporate three platforms catering for up to six-cars, a publicly accessible pedestrian overpass connecting both sides of the railway, a bus interchange and cycling facilities. A new 12-stand bus interchange and multi-storey car park with more than 600 bays will be constructed at the location of the former Midland Station. Early work on the project is due to start later this year. Causeway Bridge preferred proponent announced A consortium comprising Civmec Construction and Engineering, Seymour Whyte Constructions and WSP Australia has been selected as the preferred proponent to construct the Causeway Pedestrian and Cyclist Bridge in the Perth metropolitan area. The news came as the Western Australian and the Federal governments also committed a combined additional funding of $50 million for the project, bringing the project’s total value to $100 million. At approximately one kilometre long with a six-metre-wide shared pedestrian and cycle path, it will provide safer access for the more than 1500 cyclists and 2000 pedestrians who use the path daily. Pending contract negotiations, the successful alliance is anticipated to be established over the coming months.
