Causeway Link Bridge- Bored Piles

The Causeway Link Bridge project in Burswood, Perth, involves constructing new pedestrian and cyclist bridges to alleviate congestion on the existing Causeway Bridge, which is used by over 3,000 cyclists and pedestrians daily. This $100 million project is jointly funded by the Australian and Western Australian governments, each contributing $50 million.

The new bridges are designed to improve safety and connectivity between Victoria Park, Heirisson Island (Matagarup), and the Perth CBD. They feature a culturally significant design inspired by the Whadjuk Noongar heritage, including pylons shaped like traditional tools and the Wagyl (rainbow serpent) to represent the area’s cultural significance.

GFWA’s scope of work for the Causeway Link Bridge project included the supply and installation of deep bored piles with diameters of 900mm and 1050mm. A total of 34 piles were installed, with depths ranging from 17 to 40 meters, resulting in a cumulative bored length of 970 meters. Some of these piles required full casing to ensure stability and integrity during construction. This work was essential to provide the necessary foundation support for the new pedestrian and cyclist bridges, addressing the engineering challenges posed by varying soil conditions and the significant load requirements of the structure.
