Kingsford Smith International Airport Car Park

The Kingsford Smith International Airport in Sydney provides a vital gateway to Australia for 16.7 million passengers per year (as at 2018) and millions of tonnes of cargo.

BG&E provided structural engineering and materials testing services for the $45 million international airport car park, which comprises 12 levels above ground car park with an external curved ramp.

The car park structure includes post-tensioned band beams spanning 17.5 metres at the 8.7 metre centre, as well as a post-tension concrete slab. Similar to the car park structure that BG&E designed for the adjacent domestic airport car park, the large spans were incorporated to meet the Sydney Airport Corporation’s requirements.

Building foundations consist of continuous flight auger piles that are 25 metres deep to reach the sandstone bed. The crash barriers were provided by using reinforced concrete upstands and tensioned cables.
