About the project
Key Details
  • About The Project

    Heritage design advice, liaison with the construction team, taking charge of all lodgements to OEH and liaised with sub- contractors including electrical, fire, hydraulic, mechanical, etc. for the existing 1920s sub- station and selection of materials and finishes for the new sub- station.

  • Summary

    Heritage 21 was commissioned by Beca Consulting Engineers to participate in all stages of the construction of a new electrical sub-station at the Charmers Street end of Central Station in Chippendale, NSW. This commission spanned the entire range of consultant input including heritage design advice, detailed documentation, site induction and participation throughout the construction phase. The work included the repurposing of the existing sub-station building that was constructed in the 1920s. This building was surveyed in detail by Heritage 21 to find appropriate new uses for the building.

  • What was done

    A new sub-station building was constructed close to the existing sub-station building- the later being heritage listed in accordance with the CMP that was prepared by Heritage 21. Many services had to run from the new sub-station into the old building and it was Heritage 21’s job to ensure that no damage was sustained to any heritage fabric in the three buildings- Prince Alfred substation, switching house and compressor house.

  • Time frame

    Approximately 4 years from design to construction completion.
