Cost Implications of Design Variables

Abstract

The costs of buildings are influenced by a variety of factors, some of which are interrelated. It is essential that quantity surveyors should be fully aware of the cost consequences resulting from changes in shape, size, storey heights, total height, fenestration and other building characteristics. The cost effect of the main design variables will be examined and compared in this chapter. The final design of a building will be influenced by a variety of factors, including user’s wishes, planning and Building Regulations requirements, site factors and aesthetic requirements. Other factors affecting cost include the form of contract, period for completion, structural form, extent of prefabrication and standardisation and consideration of maintenance and running costs, all of which will be considered in subsequent chapters.
