First concrete poured at Gold Coast dam

摘要

Construction is progressing on the stage three upgrade of the Hinze Dam on the Nerang River near the Gold Coast. The project has a total cost of $400 million and is scheduled for completion in 2010. The project is being delivered by the Hinze Dam Alliance which comprises SEQ Water and non-owner partners Thiess, SKM and URS which is the structural engineer. The upgrade will raise the dam wall by 15m to 108.5m above sea level, increasing water supply from the dam to 225ML/d. After the upgrade, the dam will have a full storage capacity of 309,700ML and will be one of the highest central core earth and rock fill dams in Queensland. The 15m raising of the embankment includes raising the existing main embankment and saddle dam as well as extending the saddle dam across the right abutment area by approximately 800m.
