Major highway infrastructure project recognised for sustainability


CPB Contractors delivery of Transurban Queensland’s $512M Logan Enhancement Project was recently recognised for its demonstrated leadership in sustainable infrastructure by the Infrastructure Sustainability Council of Australia (ISCA).

 

The major highway infrastructure project which was completed in August 2019 was certified with an IS Leading As Built rating for avoiding 17,093 tonnes of CO2-e emissions, reducing energy by 9.8 percent, water by 36 percent and materials by 12 percent.

 

It is Queensland’s first infrastructure project to receive an IS ‘Leading’ rating.

 

CPB Contractor’s LEP Environment and Sustainability Manager Christian Keyes said the reductions were achieved through a number of measures.

 

“To reduce energy use and greenhouse gas emissions LEDs were used in street lighting instead of high-pressure sodium lamps, and more efficient technology was used in the Variable Speed Limit Signage,” he said.

 

“Electricity was used to power site offices instead of diesel-powered generators and we used solar-powered light towers during construction.

 

“We also implemented water saving initiatives and carefully monitored water use to ensure every drop was used efficiently.”

 

The project was also the first major road project in Australia to lay Enrobes a Module Eleve Class 2 (EME2) asphalt at commercial scale. The use of EME2 reduced the quantity of asphalt used in pavements throughout the project by 23 percent when compared to traditional asphalt pavements.

 

“This product has enormous economic, environmental and social benefits and its use on this scale has set a benchmark in the road construction sector for sustainability of pavements,” Christian said.

The IS Rating Scheme is Australia and New Zealand’s only comprehensive rating system for evaluating sustainability across the planning, design, construction and operational phases of infrastructure programs, projects, networks and assets.

 

The Logan Enhancement Project included upgrading parts of the Logan and Gateway motorways, improving key congestion hot spots (Mt Lindesay Highway/Beaudesert Road interchange and the Wembley Road/Logan Motorway interchange) and constructing new south-facing ramps at Compton Road.
