摘要: AbstractThe design–build (DB) delivery method has been widely used in the United States due to its reputed superior cost and time performance. However, rigorous studies have produced inconclusive support only terms of overall results, with few attempts being made relate project characteristics performance levels. This paper provides a larger more finely grained analysis set 418 DB projects from online database Design–Build Institute America (DBIA), time-overrun rate (TOR), early start (ESR), completion (ECR), overrun (COR) associated type (e.g., commercial/institutional buildings civil infrastructure projects), owners (e.g., Department Defense private corporations), procurement methods (e.g., best value discussion qualifications-based selection), contract (e.g., lump sum GMP) LEED levels (e.g., gold silver). The results show best be th...
