Wharves 8&9 Walsh Bay are part of the historic precinct of wharves which were adapted for reuse as commercial offices. The wharf which is 150m long x 40m wide supports a 12 metre high timber building. This whole structure was re-supported on new piles and jacked to level. All deteriorated structural timbers within the building were replaced or strengthened.

The works included:

  • installation of 120 steel piles and 200 timber piles. Steel piles were up to 30m long. Piles inside the building were driven in 2m sections in limited headroom
  • supporting the wharf and building on 28 steel beams. The beams which each weighed 4 tonnes were floated in and installed from under the existing wharf
  • reconstruction of 2600 sq.m. of concrete apron
  • construction and installation of a prefabricated plant room 14m x 6m under the wharf. The plant room was constructed off site and floated into position
  • construction of 5 plant rooms in the roof and 5 lift pits under the building
  • replacement or repair of 90 storey posts supporting the building including rejacking of the whole building to level
  • replacement or strengthening of all internal timber beams and trusses
  • construction of 450 sq.m. of timber boardwalk
