Stage 3 > Developed Design
Summary
During this stage, the Concept Design is
further developed and, crucially, the design
work of the core designers is progressed
until the spatial coordination exercises have
been completed. This process may require
a number of iterations of the design and
different tools may be used, including design
workshops.
By the end of Stage 3, the architectural,
building services and structural engineering
designs will all have been developed, and will
have been checked by the lead designer, with
the stage design coordinated and the Cost
Information aligned to the Project Budget.
Mapping to RIBA Outline Plan of
Work 2007
Stage 3 maps broadly to the former Stage D
and part of Stage E. The strategic difference
is that in the RIBA Plan of Work 2013 the
Developed Design will be coordinated and
aligned with the Cost Information by the
end of Stage 3. This may not increase the
amount of design work required, but extra
time will be needed to review information
and implement any changes that arise from
comments made before all the outputs
are coordinated prior to the Information
Exchange at the end of Stage 3.
Project Strategies that were prepared
during Stage 2 should be developed further
and in sufficient detail to allow the client to
sign them off once the lead designer has
checked each strategy and verified that the
Cost Information incorporates adequate
allowances.
Change Control Procedures should be
implemented to ensure that any changes to
the Concept Design are properly considered
and signed off, regardless of how they are
instigated.
While specialist subcontractors will undertake
their design work at Stage 4, they may provide
information and guidance at Stage 3 in order
to facilitate a more robust developed design.
