Fortec was engaged by Main Roads WA to deliver structural repairs, scour protection, and refurbishment works across eight regional road bridges throughout the Great Southern region of Western Australia.
\nThe project encompassed a combination of targeted structural interventions and full bridge refurbishments. Key works included scour remediation using fibre reinforced concrete apron slabs and rock armour, repair and replacement of deteriorated timber piles, stringers and halfcaps with steel sections, installation of reinforced concrete deck overlays, widening of bridge approaches, and construction of new safety barriers.
\nSeveral bridges required specialised methodologies, including pile wrapping and resin repairs, tidal-zone programming, and heritage monitoring during excavation. All works were undertaken in accordance with project-specific documentation and Main Roads standard drawings.
\nThe project was designed to extend the operational life of these critical regional transport assets, enhance structural performance, improve hydraulic resilience, and increase road user safety.

This is the first in a set of five to be installed, helping endangered possums and phascogales cross the busy Albany Ring Rd project.
\nThe project involved the installation of two 18 m posts, each embedded 5.5 m deep in the ground. The foundation for the piles was completed by Groundex, who drilled 750mm diameter holes to 6m deep, and stabilised these with steel liners, in anticipation of the posts.
\nThe posts were secured into the liners with concrete and further stabilised with 2 hulk anchors each. Tension wires and netting were installed between the poles, with additional rope connections to the surrounding trees, providing a safe crossing for wildlife. Th project was finalised with the installation of cameras making it possible to review the bridge usage by wildlife.
\nThe works were completed using a variety of access equipment, as working in proximity to busy traffic lanes and unstable ground conditions required it. Critical activities were conducted during the night, with minimal impact on the public.
