Concast provided a total Precast frame solution at Nutgrove Retail Park comprising 21,000 sqm of office, retail and retail warehouse accommodation above a 450 space basement car park. In designing the large open plan retail warehouse units we utilised a C4 pitched roof beam combined with multi-story columns. Our C4 beam can span up to a maximum of 36m (dependent on roof loadings) with grid jumper beams used to reduce the required number of columns. The accommodation and basement parking comprised a Precast beam and column design with a substantial transfer slab at grade to provide surface car parking for the retail park.
