Brookfield Multiplex finished the nine-storey Bishops See South Tower earlier this year, using both precast and in situ concrete elements.According to Cement Concrete & Aggregates Australia, the hybrid concrete construction method virtually eliminates formwork, saving on time and labour.“[Formwork] is one of the largest influences on construction speed and will usually determine success or otherwise of the project in terms of budget and schedule,” CCAA reported in its Concrete Concepts Technology Review.The hybrid construction solution makes it easier to meet Perth office space and onsite construction labour shortages, CCAA says.In situ concrete was used for basement and podium levels, while precast concrete columns, perimeter beams and hollowcore floor decking were used in the upper areas.
