DESIGN PROCESS
The main sections of this guide provide guidance on actions that should be carried out during each of the stages 1 to 7, as defined in the RIBA Plan of Work. These are illustrated below, together with stage 0, which is not covered in this guide as no decisions relating to through-wall are made at this stage.
The outcome here may be the decision to start a project.
Projects span from stages 1 to 6.
Stage 7 covers the ongoing use of the building.
Projects span from stages 1 to 6.
ROAD MAP FOR DESIGN
RIBA STAGE 2 - CONCEPT DESIGN
Prepare concept design including outline proposals for structural design. At this stage, the form of construction will be established, including through-wall if appropriate. Early-stage U-value calculations will be undertaken to establish appropriate wall thicknesses, typically undertaken by an insulation manufacturer, based on assumed depth for the SFS. RIBA STAGE 3 – SPATIAL COORDINATION Prepare developed design including coordinated and

RIBA STAGE 0/1 STRATEGIC DEFINITION, PREPARATION AND BRIEFING
Design consultant client appointments should include a design responsibility
matrix (DRM) giving an overview of their design responsibilities and which packages will be subject to contractor’s design portions (CDP). Where design consultant appointments occur at a later stage – for instance, when appointed by a contractor to provide design services in connection with a design and build contract – the DRM may be established or renegotiated at stage 3 or 4.
