Innovation in sustainability

The North Strathfield Rail Underpass project delivered more than 200 sustainability initiatives involving community benefits, heritage, biodiversity, resource management, energy management, water management and pollution control.

The North Strathfield Rail Underpass Project involved the construction of a rail underpass for freight trains at North Strathfield, 2.4km of new track and upgrade of 850m of existing track, a new aerial concourse at Concord West Station including four new lifts and platform upgrades, and the relocation of an existing Sydney Trains depot at North Strathfield Station. The project also included the provision of new rail systems, overhead wiring of both high and low voltage, communications and signaling, and utility relocations/protection.

The project attained a Silver Sustainability rating in the Transport for NSW Sustainability Design Guidelines (SDGs).

NSRU was the first New South Wales rail project to use synthetic fibre shotcrete in a rail tunnel. The project found a more economical and sustainable replacement to using lattice girders and steel shotcrete. Using a tested mix of synthetic fibre shotcrete, NSRU met the required performance criteria for the rail tunnel while reducing CO2 emissions, minimising cost, providing longer term durability, a safer work environment and reducing maintenance requirements.

The project off-set 100% of all vegetation removal, which is being delivered in partnership with the Canada Bay City Council. Tree replanting sites include Figtree Reserve, Queens Park and St Lukes Park with site visits undertaken with TfNSW and Bushcare coordinators. These sites will be rehabilitated with native species and regularly maintained, increasing biodiversity, managing noxious weeds and creating a habitat for fauna.
