Project Details
DWW Engineering completed aluminium roof fabrication for the Keidges Road Reservoir at Augustine Heights, Queensland. The project involved the design, fabrication and installation of a new aluminium roof structure, access stair tower, roof access platform and davit arm as part of a wider reservoir refurbishment program.
The 1990 ground-level reservoir measures approximately 45 m in internal diameter, creating a significant design and installation challenge. Unlike a conventional triangular arrangement, the roof used a conical four-way sloping design, with the aluminium structure required to form a watertight interface across the reservoir.
Our team developed the fabrication model using 3D laser scanning and detailed design coordination to account for the existing tank dimensions. Components were fabricated and trial assembled before installation, supporting accurate fit-up and an efficient site program.
