Situated some 50 kilometres west of Adelaide, the Big W Southern Distribution Centre at Monarto is one of the biggest warehouse and distribution complexes in Australia.
It involved building a massive structure to house a warehouse floor area of 35-thousand square metres – similar in area to two Australian Rules football grounds.
A further football ground sized area of 20 thousand square metres was concreted around the warehouse to accommodate up to 40 semi-trailer movements per day.
The ten-and-a-half acre concrete floor is a masterpiece of construction.
Poured in sections of up to 2,500 square meters in any one day – and sometimes involving up to three pours a week, the post-tensioned slab achieved tolerances of plus-or-minus 2 millimetres in 3 metres, and just 10 millimetres from one side of the building to the other.
In all, 25 pours were required for the main building – a task which took a little over 12 weeks to complete.
