Integrated design

The BIM Overlay to the RIBA Outline Plan of Work, published by the RIBA in 2012 defines integrated design as:

‘… the completed set of design information on a project, including the work of all designing subcontractors (Performance Specified Work) that is substantially aligned. The design can be said to have been integrated when all of the subcontractor design is completed. Subcontractor design can be utilised on all forms of procurement and is typically referred to as CDP (Contractor Design Portion) or PSW (Performance Specified Work). Whilst the work of subcontractors is being integrated into the design, there are possibilities that the coordinated design may need to be amended. This needs to be carefully dealt with, particularly when several designing subcontractors are working concurrently’
