Stage 4 > Technical Design
Responsibility for Technical Design in design and build
procurement will depend on the particular circumstances.
It would be very unusual for an employer client to arrange
for Technical Design directly, although they might retain a
consultant team to monitor Technical Design prepared and
submitted by the contractor. Alternatively, the employer client
might require the continued use of their team by the successful
contractor through a consultant switch or ‘novation’. The
contractor client will require Technical Design to be undertaken.
An architect engaged in this context should establish exactly
how much work, how many drawings, etc. will be required
before agreeing a programme or fee. The contractor might wish
to impose conditions in respect of the method of structuring
and supply of Technical Design, preferred technical solutions,
materials, etc.
Management procurement
With the management procurement approach a significant
proportion of Technical Design will depend on the input of
the specialists involved with the works packages under Stage
5 and the two stages will run concurrently. With management
contracting much will remain to be resolved after the contract
and works packages have been let. Great reliance has to be
placed on the management contractor or construction manager,
and an early appointment will help the Technical Design
development. Close attention should be given to the appropriate
number of packages and control maintained to minimise the
risk of overlap or duplication. Monitoring of detail design will
continue well into the construction phase, and the Construction
Phase Plan might require regular adjustment.
The amount of Technical Design available at the commencement
of the project will be limited to the extent that much detail
information will be supplied by the works contractors by way
of shop or installation drawings. Nevertheless, the general
Technical Design will originate from the design team, and
the process of coordinating and integrating information will
continue throughout the construction of the project.
