Neumann’s were awarded the civil works contract, for the Gold Coast Convention and Exhibition Centre project, where the relocation of the major waterway, essential services and environmental issues presented some demanding challenges.
This project brought its own unique complexities as it involved several different concurrent tasks including: significant road works on the Gold Coast Highway, the widening of the waterway in front of Jupiter’s Casino, the underpinning of foundations for the monorail, the construction of a new bridge carrying all essential services and the demolition of an old bridge
A significant element of this work also involved the major realignment of an adjacent waterway. Little Tallebudgera Creek had to be moved several hundred metres west to make room for the main building pad and new bridge needed to accommodate the changed configuration.
In the earthmoving process Neumann’s environmental management team treated 40,000 tonnes of acid sulphate material which was removed from site and taken to an approved disposal facility.
Neumann Contractors supplied a level one service, testing and analysing materials to ensure they were within the acceptance criteria for water quality and other environmental issues including erosion and sediment control.
Neumann’s acknowledge the civil work challenges were managed successfully due to the team approach with builder Multiplex Constructions and consulting engineers Weathered & Howe.
- Moving an entire watercourse several metres to allow for the building pad without unduly interrupting boating or road traffic
- Treating and removing the large amount of acid sulphate material taken from Little Tallebudgera Creek.
- Recycling the old bridge meant dismantling it on site and ensuring that all materials were recycled on site or removed to a recycling centre for grading and reuse.
