Dumaresq 330kv Capacitor Banks and SVC Works

Dumaresq Substation is located in a remote area, in NSW near the QLD border. CPP contracted us to install the substation’s new SVC (Static VAR Compensator) slabs, cable trenches, various HD footings, draining, kerbing, laydown areas and access roads. The project will be completed in five stages across a six month period.

The scope of works included

• Milestone one largely involved earthworks and excavation with the cut and fill of over 50,000m3 of spoil utilising a diverse range of machinery, including scrapers, graders, dozers, excavators, dump trucks, compactors, rollers and watercarts.
• Employing our Volumetric Concrete Truck, the SVC slab and building will be installed during milestone two
• Milestone three involves construction of the new transformer bund and internal roads
• Milestone four includes the construction of two large concrete slabs to house the capicator banks, precast walls, hebal noise walls and associated structures
• In the final stage, gravel will be spread within the substation grounds

The Results

The remote location of Dumaresq substation emphasised the importance of planning. Ensuring that materials arrived on time and schuelling a rotation of employees was critical to the success of the project.
