Probuild contracted Delta Group to design and deliver an integrated works programme for the demolition of the former Queensland Government Executive Building & Annex – launching the $3b Queens Wharf Brisbane development.

The scope of works included:

  • Site preparation, including the mobilisation of tower crane, men and materials hoist, gantries and full/partial height perimeter scaffold.
  • Demolition of existing 15 storey Executive Building down to ground level, as well as the adjacent 6 storey Annex structure.
  • Separation/protection of neighbouring heritage listed structures.
  • Asbestos and hazardous waste removal.
  • Internal strip outs – all levels of both structures to maximise recycling.
  • Construction of a significant piling platform – reusing onsite demolition waste.
  • Transport logistics, including traffic management and supervision.
  • Emissions, noise and vibration controls.
  • Recycling of construction waste materials.

Due to the sheer scale and scope of the Queens Wharf redevelopment the project attracted intense public and media scrutiny. Our experience in managing complex stakeholder relationships as well as more than 10 different trades throughout the life of this project was paramount to our success.

We successfully deconstructed the Queensland Government Executive Building & Annex without disruption to high density CBD pedestrian and vehicular traffic, or damage to the adjoining heritage listed structures that were central to the future design (and amenity) of the Queens Wharf Brisbane development. Other key achievements included:

  • Onsite processing and reuse of more than 10,000t of recycled concrete to construct the piling platform.
  • Safe capture, removal and transport of 255t of asbestos contaminated materials.
  • Processing of more than 1,850t of construction waste, as well as 2,000t of scrap steel and 50,000t of concrete.
  • Recycling in excess of 95% of all waste materials.
