Design-Build Institute of America (DBIA) Exam 3 Practice

The party most likely to accelerate the work is the contractor, because they control field execution, sequencing, and how resources are allocated. When a schedule is tight or a deadline is at risk, the contractor may deploy additional crews, run overtime, bring in equipment sooner, or order materials on an expedited basis to speed up progress. All of these actions add costs beyond the original plan, creating the excess costs referenced. The owner may influence or approve acceleration and cover any premium, but the actual decision to speed up and the execution of that acceleration come from the contractor. The architect and subcontractors play important roles in design and specialized work, respectively, but they don’t drive schedule acceleration or bear the primary cost impact in these scenarios.
