ACOR were originally involved with the original Stage 1 works for the civil and services infrastructure which required thorough and detailed coordination of the infrastructure, both internal and external to the buildings.

Construction Stage 1 – Construction of an Enabling Works Carpark so that existing carparking numbers can be maintained. ACOR were involved with assessment of the existing structure which was not originally intended for carparking use, design of an access bridge and retrofitting the area to comply with parking standards.

ACOR were invited to provide services again for Stage 2.
With growth on the Woolworths business, carparking was at a premium. To maintain existing parking spaces, the Stage 2 works involved construction in two stages.

Construction Stage 2 – Construction of main carpark extension, comprising of 1,000+ new car spaces over 4 levels.
ACOR were involved with the following:

  • Structural: designed structure to carry future office building over, and allowance for extension for Stage 3 carparking;
  • Civil: design of carpark to comply with parking standards, including design of carpark access driveways with boom gates and readers, and assessment of head height clearances within the carpark; and
  • Hydraulic: design of fire services. Stage 2 did not require fire sprinklers but provision was made in the design to reticulate fire sprinklers at a later date for Stage 3.

After initial design was completed with Mirvac, ACOR were novated to the builder, Buildcorp to complete the design.
