Architecture / February 21, 2018 / .
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 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.
This is where the contractor provides the design and construction under one contract. Turnkey projects and many public private partnership developments are examples of this approach. Design and build offers the client competitively priced projects completed within rapid time frames by enabling the contractor to value manage the employers requirements and overlap design and construction operations. It is not successful where the employers requirements are poorly defined and the approach tends to produce functional architecture in terms of appearance.
The payment arrangements adopted on a contract directly affects the level of risk borne by the contractor. Where the contract is let on the basis of a drawings and specification lump sum the contractor assumes the risk for both the quantity and pricing. In lump sum contacts based on bills of quantities and remeasurement contracts the contractor assumes the risk for the pricing only. With reimbursement contracts the client assumes the risk for the quantity and pricing. The payment arrangement, therefore, directly motivates the contractors efforts to carry out the work in an efficient and economic manner. This in turn has a major impact on the final price paid by the client.
