NorthLinkWA achieves highest ever sustainability rating

NorthLink WA southern section has achieved the ultimate accolade, receiving the highest sustainability rating by an infrastructure project across Australia and New Zealand.

With a score of 95.2 points out of a possible 110, the highest score attained to date under the Infrastructure Sustainability Council of Australia’s (ISCA) Infrastructure Sustainability (IS) Rating Scheme.

The independently verified ISCA rating scheme recognises projects that can measure a significant reduction in the energy, water and materials ‘footprint’ in construction and have been designed to use less during the life of the asset too.

The scheme also recognises projects for diverting waste from landfill (e.g. through reuse and recycling of materials), minimising clearing of native vegetation, adapting to predicted climate change risks, innovation, and good stakeholder engagement.

“From the outset, NorthLink WA has been committed to sustainable outcomes, a fact that is clearly demonstrated in the achievement of this award,” Senior Project Director NorthLink WA, Rob Arnott said.

“The ‘Leading’ rating (Design and As-Built) for NorthLink WA southern section is the result of input from multiple stakeholders as well as behaviours developed as part of the partnering process with John Holland, Main Roads and the Independent Certifier (APP).” 

These include:

  • leadership by Main Roads which set an aspiration to reach a ‘Leading’ rating
  • foundations built by Main Roads and the NorthLink WA team towards the rating during project development
  • strong delivery by John Holland who worked closely with their design and construction team, suppliers and key subcontractors.

Additionally, NorthLink WA central section has achieved an ‘Excellent’ rating with a score of 70.5.

“These achievements demonstrate that NorthLink WA is a world class initiative in sustainability design and construction,” Mr Arnott said.

Ainsley Simpson, the Chief Executive Officer of ISCA said: “Main Roads has always taken sustainability seriously, having been one of the earliest adopters of the IS Rating Scheme. Congratulations on your continued commitment and leadership, ensuring communities reap the rewards that come from starting with the end in mind.”
