Research is an important part of DBIA's mission. Below are recent research reports conducted on design-build.
Design-Build Today: A Survey of State DOTs
In December 2015, the Design-Build Institute of America (DBIA) began a survey of state DOTs in regard to their design-build programs. Results from 30 DOTs have revealed that design-build has grown faster in transportation than any other market sector, and it’s still growing. DBIA’s survey asked state DOT owners how many design-build projects their department had completed, and the results show a more than 600% increase since the last survey FHWA conducted in 2002. Maximizing Success in Integrated Projects: An Owner's Guide
The Owner’s Guide to Maximizing Success in Integrated Projects is the application of the findings from a robust empirical study of over 200 capital facility projects. Using a variety of statistical methods to model the relationships between project delivery and project success, the primary finding of the study is that owners should consider an overall project delivery strategy when structuring design and construction services, rather than focusing exclusively on the delivery method. By considering how the organizational structure contract payment terms and team assembly process can work together, owners can develop a larger strategy. In particular, the study finds that those strategies which align the core project team — owner, designers, primary builder and key specialty trades — are more effective in meeting or exceeding their cost, schedule and quality goals. During the implementation phases, the study also finds that higher performing project teams participate in integrated practices and develop into a cohesive group. Documents available:
McGraw Hill SmartReport, Managing Uncertainty and Expectations in Building Design and Construction
The study is based on the presumption that design and construction is an imperfect process with a variety of inherent uncertainties. The intent of the study was to gain greater insight on what project teams can do to identify, anticipate and mitigate the conditions and factors that drive uncertainty, and how owners can adjust their expectations of project team performance to benefit the project.
McGraw Hill SmartReport on Project DeliverySystems (August 2014)
New research reveals that while owners, architects and contractors in the buildings sector all agree that the choice of a delivery system on a project impacts project cost, schedule and the potential for overall client satisfaction, perspectives on which of the three established delivery systems can best deliver these and other benefits often vary widely by player.
Design-Build Project Delivery Used for Nearly 40 Percent of Non-Residential Construction Projects, Report Shows
The results of a study conducted by RSMeans on the growing use of design-build indicate that for the first time more than half of projects above $10 million are being completed through design-build project delivery. The newly released study also confirms that the use of design-build has remained steady since its growth spurt at the end of the last decade, and also that Oregon and the Military sector are leading with the most dollars being spent on design-build projects.

Influence of Project Delivery on Sustainable, High Performance Buildings
A report that provides guidance on the impact of project delivery methods in achieving sustainable, high performance building projects. The findings are synthesized from a two-year study that collected data through 230 surveys, 92 procurement documents and 12 in-depth case studies. This report provides owners, government agencies, architects, engineers, constructors and industry trades with facts to improve decision making when selecting project delivery methods and key team members to achieve sustainable, high performance building projects.
The State of Design-Build
Mortenson Construction surveyed design-build industry leaders at the 2010 Design-Build Conference and Expo and compiled their responses regarding the state of the industry.
Influence of Project Delivery Methods on Achieving Sustainable High Performance Buildings: Report on Case Studies
The research that produced this report sought to determine the effect of delivery methods and practices on the level of integration achieved in projects and the repercussions of integration levels on the outcomes of projects emphasizing sustainability goals. It supplements and validates research that produced the previous report and consists of 12 in-depth case studies of the project delivery phase and compared them with building performance at project completion.
CII/Penn State Study
This study of delivery systems found that design-build offers equal or higher quality than other commonly used delivery methods. The main findings are that, compared to the traditionally used design-bid-build, design build delivers projects with an average 6% cost savings, 12% faster construction speed, and 33% faster overall project delivery. In fact, design-build outperformed design-bid-build in every category on a 10 point scale.
