In general it can be said that larger buildings with simple, rectangular, regular floor plans and elevations will be less expensive per sq.m. of floor area than smaller, complex shaped, curved or angular buildings. Economies of scale apportion fixed overheads to a larger extent of productive space. Simple setting out and buildable solutions encourage greater plant use and generate higher productivity and less waste. Complex layouts and details are slower to assemble and may involve a number of trades with a consequent greater risk of mistakes and defects. The degree of compartmentation and repetition will also affect the overall cost of the work. New building work is considerably cheaper than work of a repairing nature or work in existing buildings. Single storey structures tend to be more costly than buildings up to three storeys high, beyond which point they become progressively more expensive.
The issue of the cost of construction work is one that is rarely far from the minds of construction clients, design teams, constructors and, of course, quantity surveyors. The cost of constructing a building project is a primary concern for the vast majority of construction clients. Indeed one of the most common initial questions a client has is. What is it going to cost me? often followed closely by. can we do it any cheaper? Providing answers to such questions is a key objective of quantity surveyors, whose task it is to predict the likely cost of building work and to manage the evolving project design to ensure that the clients approved budget is not exceeded. This is a challenging task, which frequently involves one-off, unique, purpose made buildings, and the QS typically operates within a design team brought together specifically for that particular project.
The clients attitude towards initial versus the whole life cost of the building can significantly influence the specification. Buildings incur costs over their life time; these include initial capital costs, operating costs, maintenance, disposal and finance costs. The key decision is whether to spend more money initially on better alternatives in order to save money in maintaining and operating the facility
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.
