Project awards

Southern Cross Electrical Engineering Limited (“SCEE Group”) is pleased to announce that its Heyday subsidiary has been awarded a range of projects totalling over $70m as follows:

• CPB Contractors Pty Limited has awarded Heyday the Western Sydney Airport Stand Alone Facilities Project, comprising two major packages of works critical for airport operations and supporting key border agency functions.

Heyday’s scope is to design and construct the electrical, communications, ICT, security, and audio-visual systems, and to provide electric vehicle chargers and photovoltaic systems for both sites. SCEE subsidiary MDE Group will provide the communications and ICT services to Heyday along with the critical network cabling infrastructure to interface into the sitewide network systems.

The works are due for immediate commencement and are scheduled for completion in or around the first quarter of 2027.

• J Hutchinson Pty Ltd has awarded Heyday two further packages of electrical works at a hyperscale data centre in Sydney’s west. Commencing with the original base building contract, these two further awards will bring the total number of packages that have been awarded to Heyday at this site to six. The works on these two new packages are due for immediate commencement and are scheduled for completion in the first quarter of 2026.
