In late 2017, Ampcontrol was contracted by CPB Contractors to deliver 46 transportable Electrical Equipment Rooms (EERs) to power the WestConnex tunnel project including critical fire control, air quality and fan systems. This week Ampcontrol completed the final room, ready for dispatch to the new M5 tunnel.
Traditionally, the permanent electrical fitout for tunnels in Australia had been constructed in-situ in the tunnel, requiring large trades’ team and significant logistics of moving the required materials.
The approach adopted by Ampcontrol focussed on offsite manufacturing and provided several benefits including:
- the ability to manufacture in a controlled workshop environment which enabled increased productivity and improved safety;
- full factory acceptance testing;
- ability to store EERs offsite to be brought forward at the optimum time for tunnel construction and fitout schedule; and
- rapid install and commission with significantly less site labour required.
This represented the first time that transportable EERs had been utilised in major tunnel in Australia. The rooms were manufactured in Ampcontrol’s Newcastle operations and installed directly in the tunnel in Sydney.
“As a business, we’re extremely proud of our team’s ability to reach this key milestone for the WestConnex project, working with CPB Contractors. We’ve worked hard to ensure all 46 EERs have been manufactured and delivered on time and to specification against a demanding project schedule,” said Ampcontrol CEO and Managing Director Rod Henderson.
“While this represents an Australian first approach, the success of the transportable EERs on this project and significant benefits they offer means that we expect this to be adopted more widely in Australian projects going forward,” said Mr Henderson.
In addition, Ampcontrol also provided the temporary electrical infrastructure to power the WestConnex tunnel construction phase.
