NorthLink highest sustainability rating ever

A major road project in WA has received the highest ever sustainability rating for an Australian or New Zealand infrastructure project.

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 which can measure a significant reduction in the energy, water and materials footprint in construction and which have been designed to use less during the life of the asset too.

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

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

“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).”

Mr Arnott credited the leadership of Main Roads in setting the aspiration to reach a ‘Leading’ rating, adding that the foundations built by Main Roads and the NorthLink WA team contributed towards the rating during project development.

He said the strong delivery by John Holland, who worked closely with their design and construction team, suppliers and key subcontractors.

In addition, NorthLink WA’s 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.

Chief Executive Officer of ISCA, Ainsley Simpson, 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.”
