Wallace Creek Bridge and Road Works
This project is a combined bridge and roadworks project for Port of Bundaberg which was owned and operated by Port of Brisbane Corporation. The project links Bundaberg Port Marina with the community and businesses in Burnett Heads, and halves the distance between the two points.
The new bridge (including pedestrian walkway) and roadworks will benefit residents, create new commercial opportunities for local businesses, improve traffic flows, and provide better access to the foreshore for tourists and visitors to the city.
The project involved construction of a five-span bridge with cast insitu substructure on 27 metre long spliced PSC piles and PSC deck units. The superstructure included cast insitu concrete barrier and stainless steel hand railing. The majority of works were constructed on previously reclaimed land, with bridgeworks undertaken within a highly sensitive tidal saltwater creek and mangrove area.
HIGHLIGHTS & OUTCOMES
Bulk earthworks operations in sand.
Work in poor ground conditions.
No Flora was disturbed in the creek despite the bridge construction having a disturbance footprint just 1m either side of the permanent structure footprint.
No LTI’s during the project.
CMC utilised local subcontrators and engaged the local Burnett Heads community.
Piling works was to be undertaken by constructing sand bunds into the tidal creek to install PSC piles. 50% of the waterway could be bunded at a time. However, CMC designed and implemented a process that was cost neutral to the Client and negated the need to construct bunds into the environmentally sensitive waterway. The system utilised large cranes from the abutments to install PSC piles through abespoke fabricated piling frame. All piling was completed to Transport and Main Roads standards.
