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.
This is where the contractor works alongside or within the design team providing a construction management service. The management contractor does not undertake either the design or the direct construction work. The physical construction is carried out by specialist subcontractors, package contractors. There are two main forms of this approach: Management Contracting where the contractor employs the subcontractors and Construction Management where the subcontractors are employed directly by the client and the project is managed by the construction manager - there is no actual main contractor. Management procurement routes are associated with fast moving, complex construction projects. The early appointment of manager within the design team allows the design and construction operations to be fast-tracked while also ensuring that the required quality standards are delivered. These projects, however, tend to be expensive. Figure 1 sets out a summary of the advantages and disadvantage of various procurement approaches which may be of use in meeting project objectives.
