The Chullora Substation Control building houses the live electrical switchgear and equipment that controls the adjacent substation. As part of the upgrade of ageing assets, Multiworks was engaged as Principal Contractor directly by Ausgrid to replace the existing roof without any interruptions to the electricity network.

Works took place on the existing live control building, housing equipment for this 66kV Substation. Key scope involved ACM eave replacement, removal of roof tiles, installation of two layers of Compressed Fibre Cement sheets, installation of Colorbond sheets, reinstating existing gutters, installation of new downpipes and installation of new anchor points.

During the preliminary planning, it was noted that the height from the pitch of the roof to the soffit was greater than 0.8m. Due to the substantial height difference the existing anchor points could not be used as a means of fall arrest. As a result, Multiworks proposed and successfully implemented a construction methodology that provided a means of fall arrest utilising anchor wraps. The project achieved zero safety incidents.
