Delivering renewable energy for the Hunter

One of the last major bottlenecks between Sydney and Brisbane is now a thing of the past 🛣️

More than a year ahead of schedule, the John Holland Gamuda joint venture has completed the 10-kilometre Black Hill to Tomago section of the M1 extension to Raymond Terrace.

Together with the recently completed northern section (Heatherbrae Bypass), it creates a seamless 15-kilometre connection for motorists coming off the M1 Pacific Motorway at Black Hill through to Raymond Terrace, taking out one of the last major choke points between Sydney and Brisbane.

As part of our scope, we delivered eight bridges including the sleek 2.6-kilometre viaduct that now stretches across the Hunter River and surrounding floodplain.

The viaduct also passes over the Main North Rail Line and the New England Highway, with the works staged to minimise disruptions to rail and road traffic during construction.

A huge credit to our team and project partners for delivering a critical piece of national transport infrastructure ahead of schedule! 👏

Cairns’ future water security is one step closer! 🚰

Our team on the Cairns Water Security Stage 1 (CWSS1) project has reached a major construction milestone, with several key infrastructure elements now complete as the project moves into pre-commissioning and testing.

Over the past two years, the team has installed 30 kilometres of new pipeline, built a new ultraviolet (UV) treatment building and delivered the project’s 5 megalitre (ML) and 8ML storage reservoirs.

The three-storey administration building is also nearing completion, while pre-commissioning activities, including connecting electricity, are now underway to prepare the infrastructure for testing.

As the largest infrastructure project in Cairns’ history, CWSS1 will help secure the city's future water supply and support a growing population for years to come.

The project includes a new water intake at the Mulgrave River, a new water treatment plant and reservoirs at Gordonvale, as well as supporting infrastructure to connect the new intake to the existing network. It also includes flood resilience upgrades at Council's Behana Creek intake to improve the reliability of the region's water supply.

We’re proud to deliver this nationally significant project for the @cairnscouncil, funded by the Australian and Queensland governments through the National Water Grid.

Three giant TBMs are making Australian tunnelling history! 🚧

All three 15-metre-high, large-scale Tunnel Boring Machines (TBMs) are now excavating on the River Torrens to Darlington (T2D) Project, marking a major step forward in the construction of South Australia's non-stop South Road.

TBMs Mary, Catherine and Elizabeth are now tunnelling simultaneously beneath Adelaide, making this the first Australian underground road project to have three large-scale TBMs operating at the same time.

The three machines will excavate around five million tonnes of rock and soil, known as spoil, which will be transported by conveyor to the surface before being taken to the Project’s re-use site at Gillman.

A huge achievement for everyone across the T2D Alliance, including our John Holland tunnelling team who helped get these three giants underground and turning! 👏

The T2D Alliance is delivering the Project on behalf of the Australian and South Australian governments.

The new Badu Yarragul Water Resource Recovery Facility at Kemps Creek is officially open! 💧

Delivered on time and on budget for @SydneyWater, the new facility in Sydney‘s west is one of the most advanced water treatment plants in the Southern Hemisphere. It’s capable of treating up to 70 megalitres of wastewater every day, producing high-quality recycled water for homes and businesses across Western Sydney as well as biosolids for agricultural use.

Alongside the recycling centre, our team delivered more than 40 kilometres of treated water and brine pipelines between Wallacia and Lansdowne to help lay the foundations for a future circular economy hub in the region.

The project achieved an industry-first Infrastructure Sustainability Council (ISC) 2.1 rating, supported by a range of sustainability initiatives including a four-megawatt solar farm that will make the facility 50 per cent energy self-sufficient.

It’s a legacy project that will support population and economic growth in Sydney‘s booming west, and a fantastic testament to the industry-leading experience and capabilities of our water team and project partners 👏

Say hello to the new Melton Station! 🚉

A huge milestone for our North Western Program Alliance (NWPA) team, with the new elevated station at Melton in Melbourne’s west now open to passengers.

The official opening followed a busy three-week construction blitz that included removal of the old boom gates at Coburns and Exford roads.

These two sets of gates represent the 19th and 20th removed by the NWPA team as part of the Level Crossing Removal Project (@levelcrossings), while Melton Station is the 11th station delivered by the Alliance.

The new station features four longer platforms to cater for the nine-car VLocity trains that will run on the Line from next year.

It also boasts lift and stair access via a 16-metre-wide underpass, providing safer access and parking for the local community on both sides of the rail line.

The opening of the station is the result of a lot of hard work since construction began, including the removal of the level crossings at Coburns and Exford roads, demolition of the old station and the realignment of rail bridges over both roads.

Our three-week occupation also delivered platform extensions at Cobblebank and Rockbank stations as part of the Melton Line Upgrade, building on earlier extensions at Deer Park and Caroline Springs.

We’re incredibly proud of the works we’ve delivered alongside the Victorian Government and our Alliance partners since 2017, helping remove level crossings, build new stations and improve connections for communities across Melbourne.

As we like to say at John Holland, we’re up for the challenge of Transforming Lives!

Sydney Metro West is continuing to take shape underground 🚇

With tunnelling complete, our team is now focused on the final phase of works across our Sydney Metro West - Eastern Tunnelling Package, progressing the permanent structures that will support the future railway.

Beneath Sydney's CBD, excavation of the 27-metre-deep Hunter Street West shaft at the corner of George and Hunter streets has been completed, with excavation of the East shaft now in its final stages.

Concrete lining is progressing well in the Hunter Street station cavern, which will house the future metro platforms, and in the turnback tunnels that will allow trains to reverse direction and return to Westmead once the line is operational.

At the future Pyrmont Station, the crossover cavern has been lined, while lining works continue in the station cavern and service adits.

In the running tunnels between Pyrmont and Hunter Street, the permanent invert (tunnel floor) has now been poured, with finishing works continuing ahead of the next stage of construction. These tunnels will carry metro trains between the two stations when the line becomes operational.

Some big milestones ticked off by the team! 👏

Building the infrastructure that will transform how freight moves around Australia 🛤️

Our team is making strong progress on Stage 1 of the Beveridge Intermodal Precinct, with piling works for the new rail viaduct nearly complete.

Construction of the in-situ crossheads is now underway, with installation of the Super-T bridge beams set to follow later this month.

We were thrilled to welcome Deputy Prime Minister Richard Marles, Federal Member for McEwan Rob Mitchell and National Intermodal CEO James Baulderstone on site to see the progress firsthand.

A key part of the conversation was our focus on creating employment opportunities for the local community, both now and for tomorrow. John Holland is prioritising building capability, supporting local and social enterprise and establishing a last connection between the project and the future Beveridge community, alongside National Intermodal.

Once complete, Stage 1 will provide Melbourne’s first terminal capable of receiving 1,800-metre double-stacked freight trains, delivering direct access to the Inland Rail south network.

Great work by the team as the project continues to take shape! 👏
