The expansion at the Coca-Cola Amatil bottling facility at Northmead involved the construction of an automated high bay storage facility, associated staging areas, new truck docks, drivers amenities, new gatehouses and extensions to the existing warehouse buildings.

The high bay facility was founded on variable fill material ranging in depths from 0.5m to over 5m. Piled foundations were required to achieve the very tight defection limits necessary for the 32m high automated cranes that transport and store up to 55,000 pallets within the high bay facility. Staging area floors were constructed as post tensioned slab on ground to minimise joints and increase the speed of construction.
