At the recent Infrastructure Sustainability Council of Australia (ISCA) state conference the project was awarded an ‘excellent’ rating for its commitment to delivering an innovative and sustainable transport solution for Western Australians.

Embedding integrated sustainability principles in our design, procurement and construction processes has been paramount for the project. This means that all individuals and companies involved in the project are committed to developing and building the asset in the most sustainable way possible. 

Practices include:

• Minimising water consumption and use of potable water
• Minimising energy use and production of greenhouse gases, including use of solar power
• Sustainable sourcing of materials
• Implementing at least three State-first innovations

The project’s Sustainability Strategy, prepared to guide the direction of sustainability during planning, design, construction and ultimately in operation, identified over 130 initiatives. These include maximising the use of daylight at Airport Central Station by building a glass roof and developing concrete mixes that will reduce the volume of Portland cement used on the project.

The rating is an interim rating and will be replaced by an ‘As Built’ rating following practical completion. The ‘As Built’ rating focuses on ensuring the inclusion of design elements and measurement of sustainability performance during construction.
