Buildings affect everyone and can intrude on the freedom, privacy or rights of individuals. Statutory legislation regulates many activities of those who wish to build. Planning legislation controls the appearance and intensity of planning of buildings and may limit the extent of development on particular sites. Building control legislation establishes minimum standards and requires that buildings are safe and efficient to use. Safety legislation sets out to eliminate accidents to persons in the course of constructing the building. Environmental legislation protects society and wider environment from potential negative effects of the development process.
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.
