Parramatta Light Rail achieves record-breaking ‘As Built’ score

28 October 2022

The Parramatta Light Rail infrastructure works package has demonstrated its ongoing commitment to achieving sustainable infrastructure, having been awarded the highest ever ‘As-Built’ rating by the Infrastructure Sustainability Council (ISC).

The record-breaking ‘Leading’ score of 104.35 points reflected 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 through construction to delivery.

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 the use of LED lights to reduce energy impacts, a drip irrigation system with soil moisture sensors to reduce water, and recycling of 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 the design, construction, and operation of infrastructure. An overall ‘As-Built’ infrastructure sustainability rating for the project will be awarded following the completion of construction.
