Architecture / June 13, 2018 / Oriane
Clients who prioritise cost over speed or who require fixed price lump sums will generally experience longer development programmes, as designs must be substantially completed before tenders can be obtained. This process may take a considerable amount of time as careful thought is required to develop and refine the scheme design. The design, in turn, influences the contractors construction methods which determine length of time taken to complete the contract on site.
This is where the contractor provides the design and construction under one contract. Turnkey projects and many public private partnership developments are examples of this approach. Design and build offers the client competitively priced projects completed within rapid time frames by enabling the contractor to value manage the employers requirements and overlap design and construction operations. It is not successful where the employers requirements are poorly defined and the approach tends to produce functional architecture in terms of appearance.
