Which of the following terms refers to the contractor's testing for adjustments needed in field operations?

The term that refers to the contractor's testing for adjustments needed in field operations is Quality Control. This process ensures that the work being performed meets the specified requirements and standards throughout its progression. Quality Control involves systematic testing and adjustments, enabling the contractor to identify and rectify any issues that arise during construction. This proactive approach helps maintain the quality of the project and ensures that the final product aligns with the necessary specifications and performance criteria.

Other terms listed do not specifically focus on the contractor's ongoing efforts to test and make adjustments during field operations. For instance, Final Inspection pertains to the assessment of a completed project to ensure it meets all requirements before acceptance, rather than ongoing testing. Project Evaluation usually involves a broader assessment of the project's overall success and effectiveness rather than the specific operational adjustments. Cumulative Testing would imply a process over time but does not specifically denote the continuous nature of Quality Control in field operations.
