Western Treatment Plant Activated Sludge Plant Renewal Project

DCWC provided Infrastructure specialist Quantity Surveying services for the Western Treatment Plant (WTP) 55E Activated Sludge Plant (ASP) Renewal Project Scheme.

The project involved reviving the existing Western Treatment Plant (WTP) by enhancing a safer and more efficient biological treatment process to adhere to EPA Victoria’s strict environmental compliance obligations. At the time, the WTP was unsafe, and the use of aging equipment resulted in inefficiencies and increased maintenance costs.

These issues were addressed within the functional design, and the project scope included:

• Construction of new bioreactors;
• Construction of new associated pump stations and flow chambers;
• Construction of a new blower house, amenities building, and Master Control Centre buildings;
• All associated civil works;
• All associated pipework;
• All associated mechanical plant and equipment;
• All associated electrical and mechanical services.

Donald Cant Watts Corke (Infrastructure) provided QS services, including the submission of a functional design estimate, and was able to:

• Provide Aurecon with an accurate functional design cost estimate within a tight timeframe (2 weeks) based on the substantial amount of design information provided;
• Offer construction methodology advice for the selected scope of works (which was incorporated within the estimate);
• Maintain direct correspondence and constant communication with Aurecon throughout the cost estimate period.
