The technical scope
As part of the MEL07 data centre development, we successfully delivered the full electrical fit out of COLO 4 and COLO 5, two high density data halls each rated at 9.6 MW. The works were undertaken in a live, programme critical environment, requiring a strong focus on safety, coordination, and buildability.
Prime completed the supply, installation, testing, commissioning of the complete electrical and ITS system at Mel07 Including:
– Electrical fit out of COLO 4 and COLO 5 data halls (2 × 9.6 MW)
– Installation of owner supplied equipment:
– Main Switchboards (MSBs)
– Power Distribution Units (PDUs)
– Automatic Transfer Switches (ATSs)
– Uninterruptible Power Supplies (UPSs)
– Supply and installation of electrical infrastructure, including:
– Cable containment systems
– Copper submains
– Testing and commissioning of all electrical systems:
– Level 1 through to Level 5
This project demonstrates capability in delivering large scale, high density data centre electrical infrastructure, including critical power systems, high cable volumes, and full end to end commissioning.
