The preliminary results are promising and show sizeable differences between the procurement cost and schedule of single-step and two-step design-build. These early results help quantify the inefficiency of single-step procurement that the industry has been discussing for years.
However, since the results are preliminary, they cannot be used to make generalized conclusions because of being based on a small sample of projects. In order to use these results to inform procurement legislation with large owners, the observed differences must be validated statistically.
The DBIA/ASU team seeks procurement data from single-step and two-step projects in order to statistically validate the preliminary results of the study and render them defensible to serve DBIA members and industry. ASU has developed a survey available both online and through this PDF to collect project information related to the timing and cost of procurement for design-build projects.
To participate, visit https://www.research.net/s/ASU_DBIA_SURVEY. The survey should take around 20-25 minutes, and the ASU research team will follow-up to provide assistance if needed.
The responses received will remain strictly confidential; the data will be anonymously reviewed solely by ASU researchers and a copy of the national report will be provided to you upon publication of the research findings. Responses are due no later than Jan. 15, 2014.
