Assembling a Collaborative Project Team
Timing of contractor involvement
Contractor involvement at the start of Stage 2 – Concept Design
Contractor-led design
If the contractor is to lead the design process, it is essential that they are
involved at the start of Stage 2. This is achieved by issuing the Initial Project
Brief at the end of Stage 1 as part of the Employer’s Requirements documentation
to a number of shortlisted contractors. Bids, including design proposals,
prepared by each contractor’s design team, are submitted at the end of Stage 2.
Once these bids have been assessed, a contractor may be appointed in full or
on limited terms to develop the design during Stage 3 and prior to conclusion
of a Building Contract.
Contractor involvement at the start of Stage 3 – Developed Design
Two-stage design and build/management contracting
In this scenario, tender documents are issued during Stage 2 with a view to
appointing a contractor to undertake pre-construction duties prior to the end
of Stage 2. This allows the contractor to contribute, where possible, prior to the
design process before the end of Stage 2, when initial iterations in relation to the
coordinated design are being considered, and to be fully involved during Stages
3 and 4. The Building Contract may be concluded at the end of Stage 3 or
during Stage 4, in accordance with the Project Programme.
Contractor involvement at the start of, or during, Stage 4 – Technical Design
Single-stage design and build
In this model the design is tendered using the Stage 3 Information Exchanges
and, following the tender process, a contractor is appointed. The contractor is
then likely to undertake Stages 4 and 5 simultaneously. There may be a requirement
for some aspects of the design team’s information, which on other forms of
procurement would be produced during Stage 4, to be undertaken at Stage 3
for inclusion in the tender. This can be agreed and incorporated into the Project
Programme and the agreed Information Exchanges and included in the Design
Responsibility Matrix.
Contractor involvement during Stage 4 – Technical Design
Traditional
The design team completes its information during Stage 4 and issues it for tender.
The contractor is appointed during Stage 4 with the specialist subcontractors
then carrying out any design work stated in the Building Contract. It is likely that
the Stage 4 subcontractor design work would be carried out in parallel with
construction (Stage 5).
