Which statement best differentiates inspection from testing in CTI practice?

• A. Testing measures concrete properties using standardized tests.
• B. Both functions are identical in purpose.
• C. Inspection verifies conformance to requirements.
• D. Inspection measures concrete properties using standardized tests.

Answer: (C)

In CTI practice, the key distinction is between checking for conformance to specified requirements and actually measuring concrete properties. Inspection is about verifying that the work, materials, and processes meet the set criteria or specs—it's a yes/no check against requirements. That’s why the statement that inspection verifies conformance to requirements is the best differentiation. Testing, on the other hand, is the act of measuring concrete properties using standardized tests to characterize performance or quality, such as slump, air content, or compressive strength. The other statements describe measurement of properties or equate the two functions, which doesn’t capture the conformance-focused role of inspection.
