Woolloomooloo Wharf is the largest timber wharf structure in the Southern Hemisphere at 400 meters long, and has been a landmark in Sydney Harbour since its construction in1910. In the past, the Wharf has been utilised as a cargo facility, wool storage and a passenger terminal. It was left derelict for decades until it was redeveloped.

Key technical challenges

  • The primary tower structure consists of a composite slab and beam structure. Due to the long beam spans and thin slab, extensive analysis for footfall vibration was required to ensure the structure achieved code requirements and client expectations.
  • Working with the existing structure and developing design solutions that strengthened rather than demolished.
  • Extensive co-ordination with the mechanical engineer to develop a strategy that minimised beam penetrations and beam notches.
  • Differential shortening analysis with consideration of mega truss, steel structure, concrete structure and existing structural elements

Environmental performance

  • 5 Star Greenstar
  • 5 Star NABERs Energy and 4 Star NABERs Water ratings.

After careful restoration above and below the waterline, Woolloomooloo Wharf today houses 310 apartments spread over five levels, a 104 room hotel, 450 carparking spaces, conference facilities, restaurants, retail and significant areas of public access. The construction cost of this project is estimated at $300M.
Significant and interesting aspects of the project and Robert Bird Group’s role include the following:

  • RBG achieved savings in excess of $10 million through innovative piling solutions and lightweight hung floor systems. New steel driven tube piles, timber repairs and substructure designed for 100 year life
  • Submerged concrete plantroom for servicing the wharf
  • Recycling 880 existing 100 year old centre roadway piles
