Working in and around a busy, operational shopping centre.

The project

To expand the size of Sunshine Plaza, the largest shopping centre on the Sunshine Coast, by 50%. Keller designed and installed 250No Continuous Flight Auger (CFA) concrete injected piles.  Piles were 600mm and 750mm in diameter.

The challenge

Conducting the foundation piling with minimum disturbance to daily shoppers as well as the shop proprietors

The solution

While the ground condition were conducive to several of Keller’s pile types, CFA was ultimately selected as the most non-invasive piling methodology.

A high degree of planning and co-ordination was required at daily pre-starts in order to manage the impact of construction works around the shopping centre site. 

Dynamic Load Tests and Low Strain Integrity Testing were used to verify pile capacity and pile integrity.
