Castle Cove Control Building Roof Replacement

Multiworks was responsible for the replacement of roof metal sheets with Colorbond sheets, replacement of gutters, installation of new downpipes, construction of stormwater inlets and installation of new anchor points. Multiworks delivered all scope while ensuring the ongoing operations of the live electrical substation. A key challenge in the roof replacement works involved implementing appropriate physical protection over the existing Frequency Injection Units (FIUs). Due to the sensitivity of the assets and client requirement that only one FIU could be de-energised at a time, Multiworks developed and implemented a staged works program over the FIUs. Multiworks effectively planned and scheduled materials and resources to ensure protection over the unit while replacing the section of roof directly above. The protection was then stripped so that the FIUs could be re-energised. Additionally, Multiworks developed an innovative ‘Rolling Scaffold’ within the substation that offered fall protection and acted as a physical barrier to ensure the substation equipment was not exposed to falling objects.
