The new Brisbane Airport Domestic Terminal Carpark was won in a competitive design and construct alternate bid against a fully documented scheme.
The structure was re-engineered offering significant savings and helping Laing O’Rourke secure the project. The carpark is nine suspended levels for a total of 5,400 cars. The successful structure was a banded post-tensioned slab as a fully-framed structure with no lateral loads carried by the service cores.
- Total Car Parks: 5,400
- Levels: 9

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
