Abstract
The purpose of this study is to determine changes in quality management approaches of design-build (DB) highway projects compared to those in design-bid-build (DBB) projects. Identifying the existing challenges in the quality management procedures in DB environment requires conducting a content analysis. This involved reviewing regulations, FHWA policy documents, quality manuals, and state DOT solicitation documents. To obtain a deeper understanding of the state of the practice in state DOTs and to identify best practices in handling the identified challenges, this study conducted structured interviews of DOT personnel and industry experts. The results indicate that responsibility for quality assurance is being transferred to design-build teams. The findings of this study show six areas of changes in DB highway projects: (1) acceptance approaches; (2) selection criteria; (3) independent assurance procedures; (4) non-conformance reports; (5) cost mechanisms; and (6) pay factor adjustment.
