Abstract
Design-Build (D&B) is a method of obtaining construction services where a single organisation is retained to provide architecture/ engineering and construction services under one contract. This contrasts with the more Traditional Procurement Approach (TPA) where an architect or engineer prepares drawings and specifications and the owner separately engages a contractor through a competitive bidding or negotiated process. Research shows that there has been a continuous increase in the use of D&B over the past 15 years. A random sample of 40 respondents with an average of 20 years experience in the construction industry in Lagos, Nigeria, drawn from Managing Directors, Construction Managers, Chief Engineers, and Contractors in six different types of construction projects was taken. The survey results indicate that D&B was rated to perform better where time, cost, quality, comprehensiveness, suitability to different types of construction projects, and acceptability were of the essence and the project was highly complex. D&B is recommended subject to a more stringent contractor-selection process in order to assess reliability, sincerity, honesty and understanding of the needs of the owner.
