Auburn Substation

Project Details

Client: Railcorp

This project included the construction of a traction substation for Railcorp at Auburn, Sydney. The project was delivered on time to the standards of Railcorp.

The activities included a concrete piled and shotcrete retaining wall adjacent to the live railway tracks. The substantial site works, included excavation, deep footings, a myriad of ducts and cabling including undertrack crossings and connections to transmission line structures.

The building structure was substantial and was constructed within a very tight construction space. The site was challenging with several complexities. The substation was within the rail corridor necessitating full-time monitoring and daily safety briefings regarding hazards associated with this environment.

The site was adjacent to Rawson Street with significant traffic flows requiring ongoing traffic management for site access. The site was within a floodway that required substantial deviation arrangements for site protection.

The site had live 33kV transmission lines overhead which required innovative methods for completing construction works such as roof truss installations and heavy machinery access.

Key Challenges:
  • Traffic management
  • Demolition of the existing substation
  • Substantial flood water deviation work
