Non-volumetric preassembly

The BIM Overlay to the RIBA Outline Plan of Work, published by the RIBA in 2012 suggested that non-volumetric preassembly is:

‘Preassembly of items that are non-volumetric: i.e. they do not enclose usable space. Includes cladding panels, building services ductwork, precast concrete bridge sections, structural steelwork trusses etc.'
