Fleet Base West Low Level Bridge Repair - RPS
WA WINNER 2018
The Low Level Bridge provides critical access to HMAS Stirling at Garden Island. The bridge was constructed in 1972, comprising a reinforced concrete deck supported by steel structuring with sheet piling and reinforced concrete abutments.

Poor construction and exposure to an aggressive marine environment accelerated deterioration of the bridge, posing a risk to base operations, necessitating urgent repairs.

The project delivered comprehensive steel / concrete repair and protection to all bridge components, cathodic protection to pile caps and monitoring of expansion joints via vibrating wire gauges. Project innovations included floating scaffolds, structural steel bracing and a bespoke pile jacket system.
