The 2,000m² temperature-controlled warehouse for Sunny Queen in Minchinbury incorporates a number of engineering solutions specific to the sensitive storage of food produce. Frozen storage at -20oC, egg storage at +8oC and a chilled pallet store at +2oC make up the internal storage areas.
The building consists of a combination of office precast panels, insulated panels and onsite tilt up panels. The delivery was further challenged by the need to construct over an existing Sydney Water sewer main. To overcome this a pile supported sewer bridging slab was used. ESD considerations include the reuse of rejected heat heat from the refrigeration plant in the glycol heating system to prevent frost heave damage to the slab on ground.
