The Sydney Metro – Western Sydney Airport, Stations, Systems, Trains, Operations and Maintenance (SSTOM) Project Office in St Marys has been successfully delivered for client Sydney Metro.

The four-storey building is the central hub for the SSTOM unit who are working on the connection between St Marys and the future Western Sydney Aerotropolis.

We successfully won the job based on our in-depth proposal to create a sustainable building that could be disassembled. Our team worked closely with our subcontractors and client to create a disassembly plan to reduce construction waste and keep materials out of landfill.

“The client wanted an easy, quick build and something that was sustainable, reusable and relocatable,” said Alessandro Serratore, Built Project Manager.

“It needed to be easily disassembled but not a demountable and we needed to use sustainable materials to achieve their desired result.”

The design phase was an intense 10-week period during which we worked together with the client to ensure we were meeting their expectations.

“We utilised Digital Engineering and a digital twin to ensure we could give the client and subcontractors the highest level of detail before we began. This allowed us to work more effectively during the tight procurement timeframe, minimising risk,” Alessandro said.

“No excavation of the site was required. The structural steel is elevated which allows reticulation of services under the building.”

The design included a Cross-Laminated Timber (CLT) and steel formwork, allowing for more than 20% reduction in carbon. In total, 335 façade panels were used, we design manufactured more than 100t of structural steel and used 2750sqm of CLT. The job also included an integrated fit out including workspaces and meeting rooms.
