This is where a client appoints consultants to produce the design, select the contractor and supervise the work through to completion. The contractor is usually selected on some basis of competition. The traditional procurement route prioritises quality aspects of the project and is also effective in delivering economic designs on most projects. The chief drawback of the approach is the extended project duration due to the need to complete the design prior to tender.
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.
