The Queen Elizabeth II (QEII) Central Energy Plant (CEP) project forms the new energy plant for the QEII Medical Centre precinct, south west of Perth.

It replaces the previous plant building for two major hospitals (the existing Sir Charles Gairdner Hospital and the New Children’s Hospital) and will also service the planned Women’s Hospital.

Spanning six storeys and a total gross floor area of 11,500 square metres, the CEP consists of:

• The CEP, a stand-alone building housing a major mechanical, electrical, fire, and hydraulic engineering plant.
• Industrial workshops and waste management facilities.
• The service crossing tunnel that connects all major buildings to the CEP building.

The CEP building is comprised of a six metre deep basement and a structural steel superstructure supporting topped precast concrete hollowcore floors. The basement was constructed with contiguous pile perimeter walls and concrete columns supporting an in-situ reinforced concrete ground floor slab. The flue stack was constructed using a structural steel work frame, designed and detailed to facilitate modular construction. The façade was constructed from precast concrete panels supported off the structural steel framing and designed by BG&E.

The industrial workshops and waste management facilities replace the existing workshops and are comprised of a hybrid of structural steel and in-situ concrete construction.

The 500 metre service tunnel, measuring five metres deep and eight metres wide, was constructed with contiguous piles and an in-situ concrete floor, the tunnel is designed to support traffic loads above.
