A prestige development on the Sydney Harbour foreshore comprising multi-storey residential, commercial, restaurant and leisure facilities.
The King Street Wharf Development started in 1998 and reached completion in 2009. The AUD$800 million development precinct forms much of the eastern shore of Darling Harbour, and hosts some of Sydney’s most prominent retail, residential, commercial and entertainment venues.

Robert Bird Group, through their proactive approach to planning, delivered major savings in the development through innovative design of the following:

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.

Basement Construction

Extensive site investigations led the way for a number of site-specific, cost-efficient solutions for the construction of the below-water basements.

  • Suspended Roadway Design and Civil Infrastructure
  • Planning and design of urban infrastructure to provided efficient access in a highly trafficked area.
Permanent Basement Walls

In conjunction with the subcontractor, Robert Bird Group developed a basement wall system suitable for the poor ground conditions for use as a shoring wall during construction and a permanent basement wall in the completed building. A bentonite cement slurry wall cut off groundwater during construction, and enabled the driving of bored piers through it to provide structural support.

Efficient Multi-Storey Design

The multi-storey residential and commercial buildings at King Street Wharf feature cutting-edge structural systems and products, including profile decking for slabs, post-tensioning, and full-frame lateral stability systems.
