Professional Practice: Guideline for Quantity Surveyor Chapter 3
Full documents are needed for the tendering process – including that from
specialist sub-contractors. Time is needed to adequately prepare this. The client has
control over the design through their appointed consultants (i.e. architect). Generally
there is no design responsibility on the contractor.
Design and construction are separate sequential processes – this can increase
the overall time of the project. There is reasonable certainty on the cost of the project
because the contract figure is usually known at the outset. The contract does have
provision for cost to be adjusted later, if required.

In traditional procurement approach the client signs a separate contract with the designer
and builder. No formal relationship exists between the designer and builder.
