The rollout of this work was coordinated through the Queensland and NSW Governments. Robert Bird Group provided structural design solutions for up to 50 schools in South East Queensland, and 13 schools in Northern NSW.

Significant and interesting aspects of the project and Robert Bird Group’s role include the following:

  • Robert Bird Group worked in close association with Architectural Design teams and Building Contractors to provide flexible design solutions within a fast tracked environment.
  • By drawing on the combined experiences throughout the entire group, Robert Bird Group was able to pro-actively advise on the best structural options for the proposed school buildings and was able to consolidate design options to speed up documentation.

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.

Key technical challenges

RBG redesigned the steel plunge columns enabling complex bracing arrangements and programme hold-points to be removed, hence simplifying excavation and improving health and safety. The ground floor slab was redesigned for significant construction loads and to prop the basement wall whilst maintaining a large void to allow the core to rise.

RBG also checked all permanent works elements for the temporary loads induced by the innovative construction sequence. The construction method further reduced the ground movements, thereby minimising the risk to sensitive network rail facilities adjacent to the site.
