Call for Data: Single-Step Vs. Two-Step Design-Build

Throughout 2013, the Design Build Institute of America has been conducting a national research effort on design-build procurement. The goal of the study is to evaluate the resource expenditure and efficiency impact of single-step as compared to two-step design-build procurement. Arizona State University is collecting and analyzing project data for this study.

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.
