The Coomera Connector is a 45 kilometre north-south transport corridor connecting the Logan Motorway and Pacific Motorway interchange at Loganholme and Nerang-Broadbeach Road in Nerang.

The Department of Transport and Main Roads (DTMR) identified the 16 kilometre section between Coomera and Nerang (referred to as Stage 1 Coomera to Nerang) of the 45 kilometre long Coomera Connector project as having the highest demand for providing additional capacity between Loganholme and Nerang. The preferred arrangement has been identified as a new urban high-speed motorway having grade-separated interchanges which will provide an alternate route to the M1 for both the Coomera and Nerang river crossings.

Materials Scope

BG&E was engaged to provide a holistic durability report for Coomera Connector Stage 1 North – Shipper Drive to Helensvale Road.

The report was constructed by assessing geological, hydrological, and atmospheric data, and providing durability recommendations to the specific site conditions for concrete, steel, and polymer technology. Inaccessible items were designed to withstand 100 years without maintenance and accessible assets were designed to minimise disruptions to serviceability and utilisation, recommending durable solutions and specific characteristics to fit the project location and intended use.

The durability report was completed in November 2022.
