ARE 5.0 – PJM QUESTIONS WITH COMPLETE VERIFIED ANSWERS [ GRADED A+] Constructability reviews - reviewing the design (and drawings) to identify problems that might me the project difficult/impossible to construct asking the questions "Will this impact the cost, time, or quality of the project?" and "Will the contractor, or subcontractors, require an answer to this question in order to perform their work?" So from that it seems that it should also be looking for gap...
