to accelerate responses to questions or to communicate changes with greater efficiency.
In addition, BIM, when used in conjunction with DB, can bring the entire team together
early in the design so that valuable early information from every team member can be
incorporated into the planning and design process.
Design-build, more than any other delivery method, provides opportunities for both
owners and industry practitioners to leverage the benefits derived from these new ways of
doing business. In addition, DB can structure the most effective reward arrangements to
optimize team innovation and motivation.
As captured in the Penn State/Construction Industry Institute (CII) study by Konchar
and Sanvido, (1998), DB has demonstrated its mastery of cost containment (e.g., 6 percent
lower cost than DBB), reduction in construction time (e.g., 13 percent faster than DBB),
and overall schedule (i.e., 33 percent faster than DBB). Also, as indicated in the research
titled Independent Comparative Evaluation of Design-Build V. Conventional Design-Bid-
Build Project Delivery for Municipal Water and Wastewater Facilities, conducted by the
University of New Mexico, University of Colorado, and Iowa State University (Bogus,
Shane, and Molenaar 2009), DB had shorter project durations and 50 percent less sched-
ule growth than DBB.
These superior performance outcomes are not the result of serendipity. They are the
result of many hundreds of years of hard-earned lessons learned.
