Such kind of procurement route has several benefits as follows: The line of communication is simple as the Client has only one single point of contact with the D&B contractor; High buildability since the Architect, who is generally employed by the D&B contractor will promote the integration of the design and construction team of the project; The client will know the firm price earlier and therefore minimize the cost risk; The time need for design before the commencement of work will much be shorten since the design does not need to be finalized before tendering as compared with the tradition procurement route and therefore minimize the time risk; Completed works would be much more fitted to the design since the contractor is liable for the design details. However, design & build procurement route also has limitations as follows: Client cannot get known of the idea of final design before commencement of works and therefore increases the design/ quality risk to client; Difficult to conduct tender comparison as the tender design is not compared in the same basis; Design liability is limited by using standard form of contract; Design and build offers little flexibility for making changes, any variation of works required by client will lead great additional cost and implication to programme of works. 2
