Guide to Using the RIBA Plan of Work 2013
The architectural, building services and structural engineering designs are now
further refined to provide technical definition of the project and the design work
of specialist subcontractors is developed and concluded. The level of detail
produced by each designer will depend on whether the construction on site
will be built in accordance with the information produced by the design team
or based on information developed by a specialist subcontractor. The Design
Responsibility Matrix sets out how these key design interfaces will be managed.
Using the design coordinated during the previous stage, the designers should
now be able to develop their Technical Designs independently, with a degree of
autonomy. The lead designer will provide input to certain aspects, including a
review of each designer’s work.
Once the work of the design team has been progressed to the appropriate
level of detail, as defined in the Design Responsibility Matrix and the Design
Programme, specialist subcontractors and/or suppliers undertaking design
work will be able to progress their design work. The lead designer and other
designers, where required as part of their Schedule of Services, may have duties
to review this design information and to ensure that specialist subcontractor
design work is integrated with the coordinated design.
By the end of this stage, all aspects of the design will be completed, apart
from minor queries arising from the site during the construction stage. In many
projects, Stage 4 and 5 work occurs concurrently, particularly the specialist
subcontractor design aspects.
Stage 4 comprises the residual technical work of the core design team
members. At the end of Stage 4, the design work of these designers will be
completed, although they may have to respond to Design Queries that arise from
work undertaken on site during Stage 5. This stage also includes and recognises
the importance of design work undertaken by specialist subcontractors and/
or suppliers employed by the contractor (Performance Specified Work in JCT
contracts) and the need to define this work early in the process in the Design
Responsibility Matrix.
