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.
Insulation is an area where some look to save. Because after all, the reasoning goes, you cannot see the insulation in the walls or the attic once it is complete and who wants to spend money on things you can not see in your new home? Do not make this mistake. Not only will it translate into a lifetime of higher monthly energy bills, but it will lead to everyday discomfort with the home feeling too cold in winter and too hot in summer.
A project may be completed on time and within budget, but unless it achieves the specified quality or performance criteria it will be considered to be a disappointment or even an outright failure. High profile building failures such as Priory Hall only serve to strengthen the public concern expressed in the Egan Reports findings that 30% of buildings fail to meet the expectations of their owners. Such failures may be prohibitively expensive to rectify, dangerous and can ruin reputations overnight.
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.
