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.
The location of the project will influence its cost. High value sites attract high value developments and it is inappropriate to locate low value projects on valuable sites. Local development plans will constrain what can be built on such sites in any case. In general, urban locations are more expensive than their rural equivalents due to higher local wages, costs associated with access constraints, limited space for staff accommodation facilities and material storage, and the additional security measures required.
