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 relationship of quality to cost is often expressed in the saying that you get what you pay for. Cost is a critical factor in most building projects and some clients will seek a low price. Low price and maximum price competition, however, often have negative impacts on quality standards and achieving best value for money overall. In the current economic climate below cost tendering has heightened the risk of contractor insolvency and it may be difficult and expensive to obtain protection from this risk. Unrealistic and inadequate budgets often lead to projects becoming finance driven where cheaper options are preferred to better or more sustainable alternatives. Certain clients may have fixed budgets which may not be exceeded in any circumstances. In such circumstances the client will expect the quantity surveyor to maintain rigorous cost control during the project in order to deliver the project within budget. Designing to achieve such cost limits might curtail the introduction of beneficial features and or variations which may result in excessive running and maintenance costs later on.
