Bridge Replacements

Errinundra

As the Head Contractor, Road & Bridge were engaged by Department of Environment, Land, Water & Planning (DELWP) to design and construct five new single span bridges and upgrade 9kms of roads in the Errinundra National Park due to these bridges being burnt out in the 2019-20 fires.

The scope of works included design, geotechnical investigations, demolition of existing structures, construction of side-tracks, minor earthworks, rock beaching, steel driven piles, bored cast in-situ piles, cast in-situ concrete abutments, placement of bridge planks, deck panels and steel beams, post tensioning works, installation of bridge railing and off structure safety barriers, crushed rock pavements and road furniture.

All sites for this contract were in very remote areas so the planning and logistics for delivery of the steel bridge beams and concrete deck panels had its challenges. 

Through consultation and preplanning with the subcontractors and transport companies we prioritised and ensured we were able to get the bridge elements to site without complication. Access also proved challenging for the piling works. With no access across Goolengook River until that bridge was built, the piling rig had to track 7km into the Bee Tree Site.

Ground conditions encountered also proved difficult for the bored piles as the presence of silty materials on top of granite material and ground water, required the installation of temporary casings and the piles had to be poured using a “tremmie” method.
This project was a critical and successful link in restoring emergency & recreational access to the area.
