- Abstract
- A project delivery system defines the relationships, roles and responsibilities of project team members and the sequence of activities required to provide a facility. Several systems have evolved over the years. Construction management at risk, design-build and design-bid-build are three principal project delivery systems used in the U.S. today. This research presents an empirical comparison of the cost, schedule and quality attributes of these project delivery systems, using data from 351 U.S. building projects. The study included collecting, checking and validating industry data, significance testing of univeriate comparisons and the statistical development of multivariate linear regression models.
