The quality of the building will express the clients ambitions for a prestigious development. This may range from a top quality building with minimal maintenance requirements where all matters relating to the design are controlled by the design team to developments such as retail or industrial process where the detailed design is not critical and can be undertaken by the contractor. It may be essential to use high quality materials in conservation projects or where planning conditions have been imposed. High standards of craftsmanship will also be required on alterations and extensions to listed or historic buildings.
The choice of the material, and hence the cost, may be influenced by factors other than aesthetic qualities. For example fast-track construction projects may use a steel frame in preference to an in-situ or precast concrete frame in order to reduce overall programme durations. Although the concrete option may be cheaper, the shorter programme achieved by using steel may offset this initial cost advantage. Technical decisions such as these are made for each building element and these have a direct bearing on the eventual cost. Where considerable repetition can be achieved it may prove economical to prefabricate certain structural elements or to standardise various components and fittings.
