private construction projects throughout the nation. Projects included transportation, water, commercial and industrial efforts in a range of prices and sizes. The study compared various procurement methods, including QBS, best value, lowest bid and sole source, and a range of other factors, such as total project cost, projected lifecycle cost, construction schedule and project quality outcome. In-depth interviews were conducted with select firms and owners addressing 10 key areas: project demographics, cost, schedule, project risk, design complexity, project complexity, social factors, trust, transaction costs and performance. Lower Cost, Superior Performance Eighteen months of research yielded clear and consistent results. “QBS has a positive correlation with successful projects,” says Kingsley. “On critical measures, such as construction cost and schedule growth, QBS-based projects consistently have results that are superior to national averages.” That superiority was evident in the area where QBS is most often criticized: cost. Researchers identified a remarkable consistency among QBS projects: most demonstrated fewer change orders and stayed on budget during construction. The industry average for construction cost growth, which the study defines as the total cost of change orders as a percentage of the final construction cost, is about 10 percent. On projects employing QBS for design procurement, construction cost growth averaged just 3 percent. (See Figure 1.) Figure 1 Construction Cost Growth 10% 10% 8 4 3% 2
