The review of completed SEP-14 project evaluation reports process was used to structure design-build study survey questions and confirm the applicability of data requested. The review used available information from SEP-14 reports, the SEP-14 project database, and design-build project evaluation reports. The sample size was limited by the availability of comparable information - only 33 projects in 15 states were documented.
SEP-14 project evaluation reports provide a glimpse into the kinds of information state DOT sponsors are most likely to have and share, hence the need to be cognizant of this information when formulating study surveys. The reports suggest a variety in how SEP-14 projects are executed and documented, and demonstrate a need for a consistent reporting basis for analysis & determination of results.
Completed project evaluation reports do not provide an adequate basis for assessing design-build impacts on projects or industry, so a larger sample of completed projects uniformly reported on is required, as well as a program-level assessment. This study addresses these concerns and provides a wealth of useful information to developers and implementers of design-build projects, with the full cooperation and assistance of STD design-build program managers and project leaders.
With 14 available observations, the review found that there was significant difference in the mean project duration between design-build and design-bid-build projects. The average duration is 583 days for design-build, compared to 1,215 days for design-bid-build. This is illustrated in Exhibit F.1.
With six available observations, the review found no significant difference in mean cost between design-build and design-bid-build projects. The average project cost was $18.4 million for design-build projects, and $18.9 million for design-bid-build. This is shown in Exhibit F.2.
With 10 available observations, the review found significant differences in the additional project cost per change order. The difference was 0.6% of project costs for design-build projects compared to 6.0 percent for design-bid-build projects. This is illustrated in Exhibit F.3.
Only about 10% of the design-build project evaluation reports required by FHWA were submitted. Completed reports were prepared by persons familiar with projects, and most of the reports submitted were of high quality. However, the reports lack consistency in structure, contents, format, and terminology, and the sample size is not statistically significant for the population of design-build projects. These issues demonstrate the need to conduct the full design-build study program and project surveys.
