Opal Tower is a 400-apartment residential development situated in the Sydney Olympic Park. The development is the tallest in the area and boasts 360 degree views across Sydney.

The WGE team were involved in the full design and shop drawing documentation for the hydraulic services which involved detailed coordination with the construction team as well as advice to the contractors.

The large structural offsets at the base of the towers created a particular challenge. The difficulty was in the coordination of transferring sewer and storm water services through the deep transfer beams and large transfer slabs.

Due to the height of the building which imposes excessive pressures on the pipework and fittings installed on the lower half of the building, the WGE team came up with a unique dual stage pressure control concept and conducted a series of experimental tests to simulate the real working condition of the system before specifying it for installation in the building.

The team utilised innovative design methods to find efficiencies and significantly reduce the cost and personnel hours on the project whilst improving the end user experience.
