6. How is D&B generally used?
•Early start –Contractor required to build before design is
completed and appoints architect to help with design
•Works fully designed by Employer’s design team –
Contractor takes single point liability
•Employer’s design team produces outline spec and
performance spec for tendering –Contractor completes
design
•“Mini-D&B” –Contractor designs only part of Works, e.g.
foundations

8. Tips from experience
•Recommended for less experienced developers
•Employer’s Requirements are usually drafted to take precedence over the
Contractor’s Proposals in the context of single point design responsibility so
carefully consider any proposal to do otherwise
•The Contractor’s design obligations should be subject to exercising the standard
of care, fitness for purpose obligations are not generally insurable
