The Port Pirie Regional Sports Precinct involved construction of a new aquatic centre facility, function centre and light towers on soft alluvial clays. Due to the high groundwater table, a CFA solution was preferred. Belpile provided a design and construct alternative for the piled foundation scheme, which was offered to the local council during the value management phase, providing a significant cost and time saving to the project. The re-design to a smaller diameter pile across the project also allowed the use of smaller piling machinery, which suited the underlying soft subgrade and minimised the design thickness of the piling platform. It also reduced the spoil volume to handle on site which was significant in an acid sulphate soil environment.
Over 300 CFA piles were installed, with the design optimised and verified through two full scale static load tests up to 150 tonne and calibrated to additional Cone Penetration Tests (CPTs) across the site. Drilling conditions were also monitored on site with full automated monitoring. Belpile worked closely with the project team to ensure the design details around the more detailed pool structure improved the overall constructability on site.
