Lend Lease has awarded AWMA the penstock component of Sydney’s high profile $6 billion Barangaroo South urban regeneration project.
The District Cooling Plant (DCP) is a key element of commitment to sustainability at Barangaroo South. Sea water will be used in the DCP condenser cycle as an efficient cooling medium. The AWMA penstocks and screens isolate and protect the seawater system intake.
The contract requires AWMA to custom design, manufacture and install specialised water control gates, intake screens, lifting devices, storage rack and portable gantry system.
Three TLF penstocks will be manufactured from GR2507 super duplex stainless steel to accommodate the corrosive seawater environment, providing a 100 year design life.
The specialised water control gates are designed to withstand 30tn water load with a design compliant to earthquake loading including seismic load from water column. All penstocks will be fitted with AUMA 3-phase actuators.
Aluminium stopboards, CuNi screens and access platforms will also be provided. The primary screens are designed for impact loading whilst the fine screens are removable for cleaning via AWMA’s self engaging lifting frame.
The site is destined to become the greenest and most advanced financial district and the first large scale, carbon neutral precinct in Australia.
