Jaybro’s concrete crash barriers part of Australia’s biggest rail project

Deltabloc DB80 Concrete Barriers

  • Project: Sydney Metro rail project - Blues Point Temporary Retrieval Site
  • Customer: John Holland CPB Ghella (JHCPBG) JV
  • Time period: August 2018

The project

Jaybro supplied concrete crash barriers for part of the City & Southwest Sydney Metro public transport project.

Sydney Metro is Australia’s biggest public transport project to date. With a price tag of $12.5 billion, the metro rail system is being extended from the north west, under Sydney Harbour, through new underground city stations and beyond to the south west. By 2024, Sydney will have 31 metro railway stations and a 66km standalone metro railway system, revolutionising the way Australia’s biggest city travels. Major construction players John Holland as part of a joint venture with CPB Ghella were awarded the contract, and stage 2 of Sydney Metro is now underway.

The Stage 2 City & Southwest Project will deliver seven new train stations, taking the total in this region to 18. The Stage 2 project will result in a rail system spanning 30 kilometres from Chatswood to Bankstown, more than 15 kilometres of which runs directly under Sydney Harbour and through the city to Sydenham via a twin tunnel rail line.

Tunnelling commenced in 2018 on the twin tunnels that extend from Chatswood to Sydenham. Throughout the build, specialised boring machines will be used to tunnel under the city’s bustling CBD, and a dedicated site set up to enable the tunnel boring machine’s cutting heads and shields to be removed at set intervals.

This temporary site is located in North Sydney’s Blues Point Reserve. For the duration of the project the site will be used for the cutter head and shield removal events, each of which can take up to a month to complete. Four of these removal events are slated to take place at Blues Point. The site will also be used for diverting utilities such as water, sewer lines, gas and electricity, and will act as a hub for additional excavation works.

At the completion of the project, the site will be backfilled and the parkland restored in consultation with North Sydney Council.

The challenges

With construction activities including excavating the tunnel shafts with rock hammers and blasting, along with the dismantling of the tunnel boring machine, a host of massive plant and equipment would be located on site. Therefore, the safety of workers was a key priority, as was the security of the temporary site. Standard site sheds and amenities formed part of the area, along with storage for excavators and other equipment. With a boundary line pressing up against the waterline of exclusive Lavender Bay, safe pedestrian thoroughfare outside the edges of the site was also a factor. 

Jaybro's solution

Jaybro supplied John Holland CPB Ghella (JHCPBG) Joint Venture with 68 metres of Fortress Fencing Deltabloc DB80 Concrete Barriers to the coastline at the temporary retrieval site. These concrete barriers are surprisingly light, flexible and rigid, as well as being RMS approved to minimise impacts from vehicles travelling up to a blistering 100km/hr. Available in 2, 4 and 6 metre lengths, their unique design allows for fast truck-mounted crane installation.

Anti-Gawk Screens were also installed on top of the Deltabloc concrete barriers. These galvanized mesh panels reduce the visibility of work site activities to pedestrians and the general public, and help to prevent trespassing.

The Stage 2 portion of the project is set to be completed in 2024.
