The Rookwood Weir project is a major infrastructure project in Queensland, Australia. The project involves the construction of a weir (Dam) on the Fitzroy River near Rockhampton, which will create a new storage reservoir for water supply, irrigation, and flood mitigation purposes. The main purpose of the Rookwood Weir is to provide a secure and reliable water supply for the region, particularly during periods of drought.

The Client, Acciona, has awarded BAUER Foundations Australia Pty Ltd with the contract to construct an 800 mm wide plastic concrete cut-off wall (CoW) for the Rookwood Weir project. The CoW consists of 23 panels spanning approximately 112 linear meters, with depths ranging from 30 m to 44 m socketed into basalts. Bauer will be using BAUER BC 48 trench cutter on a BAUER MC 96 duty cycle crane and HS855 with grab for the project.

Additionally, BAUER has been involved in the preliminaries stage of the project, which includes reviewing the project performance criteria such as permeability, UCS (min and max), strain at failure, and elastic modulus. BAUER also provide the construction procedure for the plastic concrete cut-off wall, including performance criteria and embedment depth.
