Who approves testing locations that are determined by a random number generator?

• A. The Client
• B. The Planner
• C. The Site Supervisor
• D. The Engineer or Department

Answer: (D)

The person who approves testing locations determined by a random number generator is the engineer or the department responsible for QA/QC. They hold the authority to approve the sampling plan, ensuring it aligns with project specifications, provides unbiased and statistically valid coverage of the work area, and complies with contract requirements. The planner may design the sampling approach, and the site supervisor may execute tests, but the final approval of where tests occur rests with the engineer or QA/QC department to maintain accuracy and accountability. The client might oversee the project and review results, but they typically do not approve the specific test locations.
