The availability, location and capacity of existing utilities must be considered in the design. Connecting to these may involve significant costs particularly where they are inconveniently located or are distant from the site. For example septic tanks or pumping plant may be required to drain a site, easements may be required to cross neighbouring land, and diversions of live services may be required to accommodate the development.
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.
Speedy completion is often required on commercial developments. The pressure to achieve early completion intensifies when financing and interest costs associated with acquiring the site begin to mount. Clients will seek the early appointment of a contractor in these situations to enable a fast start up on site and will favour fast track design approaches where the design is developed in parallel with site construction operations. Such approaches risk allowing insufficient time to identify or consider beneficial design options, and may, on occasion, lead to abortive working and losing time. Speedy construction on site often requires accelerated working and shift or overtime payments, more intense management presence, and the use of dependable subcontractors and suppliers, all of which add to the cost of the project. Fast track approaches rule out cost certainty and the client will become aware of the eventual cost only at an advanced stage of the project.
The notion of quality is multidimensional and includes aspects which may be appraised subjectively. The Latham Report identified a number of quality aspects which clients may seek in a satisfactory construction project: pleasing to look at; free from defects on completion; fit for the purpose; supported by worthwhile guarantees; satisfactory durability and customer delight. Several of these aspects are inherent in the design of the project, while others relate to how successfully the contractor constructs that design on site. The designers will aim to produce an effective and attractive spatial and structural solution to the clients brief. This should provide sufficient, well planned accommodation, using appropriate materials, components, equipment, fittings and furnishings to enable the building to perform effectively and efficiently. Ideally it should generate a sense of delight amongst it users and the public at large.
