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 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.
