In March 2021, the District Court of Western Australia (WA) celebrated 50 years of justice in the region. The District Court building was redeveloped via Public Private Partnership (PPP), which included the construction of a 14-storey building that is linked via cross bridges to a four-storey building.
Working within a tightly constrained site footprint of 60 by 60 metres, BG&E provided structural engineering services for the redevelopment, including using contiguous piling for the perimeter retaining wall and as support for some of the perimeter columns, and Continuous Flight Auger (CFA) piles and pile caps as foundations for the internal columns and cores.
The 14-storey building features five core walls that provide separate access for the various types of visitors. These cores are separated by a 14-metre clear span. This was initially detailed and constructed using precast planks and was subsequently updated to in-situ, post-tensioned beams and a slab system above level three, in order to reduce the dependence on the type of craneage that was required.
