The contract documents set out what work must be done, and how, and under what conditions it is to be done. They identify the contractors obligations and liabilities and form the contractual agreement to do the work for the stated price or at the agreed rates. Many if not most financial problems in building originate in inadequate or unclear tender and contract documents, often culminating in disputes between the client and the contractor over what is included in the price for the work.
The materials specified and the proposed construction details will have an important bearing on the cost of the project. The relationship of quality to cost has been commented on above, and buildings which incorporate high quality and innovative features are invariably more expensive than those which are purely functional. The choice depends on what the client is willing to pay. The materials, nevertheless, should be appropriate for their use; over-specification is wasteful.
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
Many construction projects involve the design and construction of a building which is tailored to meet the clients specific requirements. No two construction projects are identical - there is no such thing as the average building project. The cost of the building will depend on its particular characteristics and these are largely determined by the architect. The design options are almost limitless and the resulting costs can be difficult to forecast reliably in many cases. On the other hand, certain types of buildings such as schools have well established cost histories and are usually subject to a cost limit.
