Encouraging sustainability action

BPC’s Whakawhirinaki Silverstream Pipe Bridge project has been celebrated by Water New Zealand for achieving great carbon reduction outcomes. The project is showcased in WaterNZ’s new Embodied Carbon Guideline for industry as an example of good practice.

Delivery Outcomes Manager Matt Findlay says case studies are a great way to encourage action in sustainability and share successes. “The 60%+ carbon reduction at Silverstream is a really significant outcome and is very deserving of inclusion in an industry guidance document.”

As an Early Contractor Involvement project, BPC worked directly with the designers to make carbon-reducing changes like shifting from a concrete to a steel structure, unlocking reductions in piled foundations and the embedded carbon in the super and substructure.

The Silverstream team have nearly completed the project for Wellington Water, which includes a 200m long bridge carrying a seismically resilient concrete-lined steel water pipe and a shared pathway for pedestrians and cyclists.
