A designed object is a multi-storey car-park in Woking near London. This is one of a couple of already existing car-parks in town, which is an interchange station for people commuting to London. Main load-carrying structure is steel structure which stiffness is ensured by 3 precast concrete cores. Our task was to create a structural model of Core 2 and therefore a delivery of production drawings for panels with general assembly drawings for core and IFC model.
