Volumetric construction
Volumetric construction relates to modules constructed in a factory that are installed on site to form a cellular system (or used independently as a self-contained cell).
The modules can be cast as a room or as panels which are subsequently joined together in the factory prior to site delivery. For a cellular system, the ground floor cells are laid on pre-prepared ground floor slabs with individual modules lowered into place usually forming the roof of the unit below. Cellular systems are used for repetitive designs. Common uses include hotels, prisons, student halls and residential buildings. Self-contained cells are used mostly for specialised purposes where services are needed such as wet rooms, bathroom pods and service utility rooms. Once lifted into place, the modules are secured by a number of methods including bolted and doweled connections.
