Construction involves the production of large scale capital assets which affect not only the client, designers and constructors but also users, the public, and the environment at large. Common law regulates the rights and obligations of the contracting parties not only to each other but also their duties of care to society in general.
Many people will choose a new home because they want to be as maintenance-free as they can. They do not want the headache or hassle of failing systems. But when you choose lesser-quality finishes in appliances, tile, flooring, roofing and windows to achieve size, these items, too, will fail sooner than a higher quality item.
Procurement refers to the process of obtaining goods and services from another for some consideration. They describe the process as being simple in theory – balancing quality, time and cost priorities, but complicated in practice by legislation, the need to achieve value for money, demonstrate accountability and coordinate consultant and contractual roles and obligations to achieve a satisfactory outcome. The procurement strategy identifies how the project is structured and establishes where responsibility for design is to be placed, how the work is to be co-ordinated, and on what price basis the contract is to be awarded. The procurement strategy also directly affects the level of risk borne by the contractor and leads to choices regarding the conditions under which the work will be executed. These risks must be appraised and managed by the contractor and has a direct impact on the price tendered by the Contractor
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.
