Architecture / June 21, 2018 /
The materials specified and the proposed construction details will have an important bearing on the cost of the project. The relationship of quality to cost has been commented on above, and buildings which incorporate high quality and innovative features are invariably more expensive than those which are purely functional. The choice depends on what the client is willing to pay. The materials, nevertheless, should be appropriate for their use; over-specification is wasteful.
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.
