The Fremantle Rail Bridge is a twin line structure, crossing the Swan River between Fremantle and North Fremantle.

Client Brief

Past inspections of the bridge substructure indicate damage to the concrete elements and subsequent assessment undertaken the Public Transport Authority of Western Australia (PTA) confirmed the steel reinforcement of pile caps and skirting panels of the Fremantle Bridge are experiencing corrosion induced by ingress of chlorides. Based on the deteriorating condition MCM were engaged to undertake concrete repairs, protective coatings, and installation of a cathodic protection system to the original concrete substructure, carried out across multiple piers simultaneously without affecting the waterway below or the rail network above. 

What we delivered:

  • Design of ICCP system targeted to protect the reinforcing within the pier structures 

  • Access installation including a bespoke handrail system around the perimeter of each pier

  • Survey of each element of the bridge 

  • Concrete repair on top of the piers and the associated skirting panels 

  • Installation of Discrete and Ribbon Anode system
