Client/company

Powercor Australia - an electricity distribution company that operates throughout western Victoria.

Consultants B2B Project & Construction Management handled the project on behalf of Powercor and contracted Raysett Constructions as commercial builder for the hangar, who Central Steel Build worked under. 

The brief 

Undergoing a large upgrade of facilities, Powercor employed B2B Project & Construction Management to oversee the project who approached us directly for initial costings of a helicopter hangar. 

As the project progressed, B2B engaged Raysett Constructions as head contractor. Raysett Constructions then contracted Central Steel Build for the supply and installation of the hangar to house Powercor's fleet of line inspection choppers.

Challenges + solutions 

The hangar needed to be erected over an existing 600mm thick concrete slab which was used as a jet engine test bed. We needed to factor the thickness of the slab into our design which meant the hangar sliding doors couldn't be ground run. To overcome this problem, we top hung the doors which is not often done on a building of this width. This required a very heavy front truss designed to take the loading. Additionally, CSB custom designed a continuous concealed ground guide system that could be bolted to the existing concrete.

The new hangar slab required a lot of thought as to how it would be integrated ontop of the existing slab which contained 300mm of fall. The final solution was to pour a new slab on top of the old one and tie it in.

CSB also custom designed the outrigger system to work via a single outrigger with two supports. This ensured the outrigger would be strong enough to take two doors deep.
