Faced with the challenging long distance logistics of constructing the huge Perth to Bunbury highway upgrade in Western Australia, principal contractor Southern Gateway Alliance appointed Granor Rubber & Engineering to supply the 464 structural bearings and 646m of expansion joints for all 19 bridges built for the project.
The Southern Gateway Alliance (consisting of Leighton Contractors, GHD, PMR Quarries and Ransberg) selected Granor because it has the skills and facilities inhouse to design, manufacture, and test the full range of bearings and joints needed for the new bridges.
Granor’s contract scope included design advice and co-ordination with GHD on critical aspects of the POT bearing and finger joint designs and detailing. The AUS$1m contract was completed on time and Granor achieved all required quality, testing and documentation requirements.
The Granor products supplied included:
- 220 laminated elastomeric bearings, up to 750mm diameter in size
- 124 POT type structural bearings, up to 12,250kN capacity
- 120 approach slab bearing assemblies
- 582m of Granor Stripseal AC-AR expansion joint system
- 64m of Granor ETIC type EJF galvanised steel finger joints, up to EJF-360 in size (360mm total movement capacity)
Due to the 70km length of the highway, a key element of this supply contract was careful co-ordination between Granor and Alliance construction staff, to ensure accurate product identification and specific delivery locations for the various components.
The successful delivery of the bearings and joints for this major contract demonstrated Granor’s professional capabilities as the one-stop-shop for structural
bearings and expansion joints for major infrastructure projects.
