The site topography i.e. the natural site features, ground conditions and obstructions, existing and adjoining building, and underground and over-ground services all impact on how the building is designed and subsequently constructed. The nature of each site must be individually checked to establish potential problems. Greenfield developments cost less than brownfield sites which may incur significant demolition, site clearance and remediation costs. Heavily sloped sites require extensive stepping or cut and fill operations and such sites may be dangerous and adversely affect the working conditions and productivity of operatives and plant output. Sites with poor loadbearing capacity will require more expensive foundations while exposed or waterlogged sites will also reduce overall productivity. The cost of dealing with unforeseen ground conditions, archaeological finds and encountering uncharted buried services may be substantial and will be borne by either the client or contractor, depending on the form of contract employed.
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.
