The Lurnea stages 3 and 4 project provides a 9,500m² extension to Swire’s existing cold storage facility in south western Sydney. The project consisted of 6,500m² of frozen storage space (-27ºC), 3,000m² of refrigerated annexe area, 400m2 of office space, 300m2 of battery charge room, 5,000m² of external hardstand area and a further 700m² of new car parking for the complex. The steel framed building with 14m springing height includes PIR insulation panels and a concrete flooring system laid over a passive floor ventilation system. The project is built with 50% of the freezer on a suspended slab structure over a flood storage area to meet Council requirements.
