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.
Once a decision to build has been reached the client will be anxious to have the building completed as quickly as possible. For many clients early completion may be the overriding priority, for example where staging a major sporting event is scheduled, or where a client is attempting to establish a market presence ahead of competitors, or to avail of tax incentives. Time is also of the essence in emergency situations such as fire or flood damage or where stabilisation works are required to dangerous structures.
