The design-build delivery method is increasingly used in the United States due to numerous advantages it can offer a project. An important issue associated with design-build delivery is the procurement method used to select the design-build team. It is a critical decision that involves several key project team members, including the owner, designer, and contractor organizations, and requires the owner to carefully choose the design-build procurement method that will be used to select the team that will deliver the project. This research quantitatively analyzed the correlation between the design-build procurement method and the performance of the design-build project with regard to cost, time, and quality metrics. The procurement methods studied were sole source, qualifications-based, best value, and low bid selection. Data were collected through surveys from 76 design-build projects in the United States. Based on the patterns and relationships identified from these data, a better understanding of the procurement process and how it influences project performance is achieved. The impact of project-specific factors and guidelines are presented to assist owners in selecting the design-build team procurement method that responds to their project goals.
