ISCA

JHCPB is required to achieve an Infrastructure Sustainability Council (ISC) IS rating of ‘Excellent’ in both the Design and As-Built phase. At the commencement of the Project, JHCPB undertook an interim assessment of the 15 categories of the IS rating tool and committed to an aspirational target of 86.8 points (‘Leading’ rating).In late 2021 the Project received its Design Round 2 rating, achieving a Leading score of 88.8. This is the highest design score received on a WestConnex project to date.

JHCPB is now working on its As-Built rating, and has a strategy in place that targets a ‘Leading’ rating. An internal progress review of IS rating credits is regularly undertaken to identify gaps in the evidence and areas that can be improved.
