The construction industry is re-evaluating the traditional design-bid-build method of project delivery and exploring alternatives. Rather than architects designing a project and then, after the fact, involving a contractor to bid and build, the new trend is for “integrated project delivery” with designers and builders working together from the start of a project with a single contract for both design and construction services. In fact, half of all U.S. states now favor an integrated design-build approach, which reduces the likelihood of schedule-stops and delays, budget over-runs, change orders and other conflicts.

Studies have found that a design-build delivery system can cost 6% less and result in 34% faster project completion compared to the traditional design-bid-build format. New York requires design-build on some state contracts, claiming that infrastructure projects in particular lend themselves to this integrated approach and could save New York City alone $2 billion over the next decade.

There continues to be ongoing dialogue over this practice and trend.
