Highest ever ‘As-Built’ rating has been awarded to the Parramatta Light Rail project in New South Wales by the Infrastructure Sustainability Council (ISC).

The record-breaking ‘Leading’ score of 104.35 reflects the project’s commitment to achieving social, economic and environmental outcomes for the wider community.

The project was again recognised as a leader in sustainable infrastructure after achieving a leading ISC rating for our design last year. It continues to embed sustainability initiatives from construction to delivery. 

CPB Contractors and Downer Joint Venture are the main contractors for Stage one of the Parramatta Light Rail project. This rating showcases the project’s spectacular commitment to sustainability, demonstrating leadership and securing beneficial outcomes for the larger community. 

Three key innovations contributed to the project’s rating:

  • an Australian-first encapsulating rail boot system to reduce operational noise and vibration
  • the use of macro synthetic fibres in the concrete track slab to reduce steel reinforcement and increase durability
  • NSW’s first ‘green track’ to reduce noise and urban heat while integrating with heritage and sensitive environments.

Other measures included using LED lights to reduce energy impacts, a drip irrigation system with soil moisture sensors to reduce water, and recycling materials.

Through a range of initiatives, including the reuse of rail, sleepers and ballast from the former Carlingford heavy rail line, the project has managed to reduce its overall greenhouse gas emissions by more than 76,000 tonnes.

The ISC rating scheme is Australia’s only comprehensive rating system for evaluating sustainability across infrastructure design, construction, and operation. An overall ‘As-Built’ infrastructure sustainability rating for the project will be awarded following the completion of construction.
