To help you understand the potential resource efficiency opportunities for your project we have created a resource efficiency opportunity matrix [PDF, 126 KB]. This simple matrix can assist project managers and project teams to assess and identify relevant resource efficiency opportunities at different stages of the development, delivery and maintenance of transportation infrastructure.
Sustainability rating tools
Greenroads® is a sustainability rating tool that encourages smart design and construction choices and provides a framework for project teams to consider and implement sustainability initiatives. Waka Kotahi requires all high value state highway projects over $15 million that are delivered via design and construction, alliance or public-private-partnership delivery models to seek Greenroads certification. Greenroads includes credits for resource efficient practices.
Recycled material use and specifications
Of the 670,000 million tonnes of aggregate material and 17,800 tonnes of bitumen binder used on state highway improvement and maintenance projects in 2019, about 2% of road pavement material and 5% of road surface materials use recycled materials. Typical recycled materials include crushed concrete, melter slag, glass and recycled surface material.
Waka Kotahi allows and encourages the use of selected recycled materials:
Energy efficient street lighting specification
Street lights controlled by Waka Kotahi consume approximately 6 million kWh of electricity per year and represent a major energy and carbon cost for Waka Kotahi. Moving towards LED lights represents a unique opportunity to reduce energy consumption by up to 60%. Waka Kotahi provides guidance and specifications for LED lighting:
