When commissioned in 2008, Polaris Data Centre set the benchmark as the most advanced facility of its type in the country. The data centre was designed as a primary and secondary facility and acts as a disaster recovery site, internet data centre and carrier interconnect exchange. 

Polaris Data Centre has been purpose-built on a greenfield site to host mission-critical ICT systems for Government departments and corporate enterprises. The project facility was fitted out to 800 watts per square metre of rack power across the raised floor area and is Queensland’s only Tier 3+ co-location facility. 

Robert Bird Group provided structural engineering solutions for the project, from concept to completion. The structure features high load capacity concrete floors to support IT infrastructure, plant and equipment, a superior level of earthquake load resistance for post-disaster functionality, and a long-span steel roof providing ease of access for replacement of plant and equipment located on the top floor.

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.

Engineering services provided by RBG for the Docklands Library project consisted of two major components:

  • Structural Assessment of the existing Wharf Structure, Structural Design of the Library Building,

Wharf Structure component included the following:

  • Assessment of load carrying capacity of the existing timber piles, Development of rectification measures to enhance piles capacities. Assessment of the wharf deck capacity and durability.

Library Building component included the following:

  • Polished concrete ground Floor slab, Design of CLT walls and floors, Lateral stability design.
  • Design of timber columns and beams, Design of structural steel and timber elements of façade.
  • Design of secondary steel structures on the roof of the Library Building.
