ABSTRACT
Contractors' main concerns are with aspects of buildability and profitability and the fact that a design and build project places a much greater responsibility on the design and build contractor. The contractual arrangements that are used for design and build can vary considerably. In some cases, the contractor is invited to design and then build the project. However, the single-point responsibility will reduce administration, contractual claims and litigation as conflicts between a designer and constructor are eliminated. Negotiation will be sought where a relationship already exists between the employer and the contractor or in those circumstances where the particular specialist skills of the contractor are sought by the employer. The primary motivation of design and build, in preference to other forms of procurement, is to eliminate the inherent conflicts that exist between the architect and the contractor. Constructability is an important component in ensuring that a design concept can be easily developed into an efficient and effective building programme.
