Under what condition is independence of the testing laboratory required on USACE projects?

• A. Always required for every test
• B. Required to avoid conflicts of interest or bias when specified
• C. Never required
• D. Only for supplier supplied materials

Answer: (B)

Independence of the testing laboratory is required only when the contract documents specify it, to prevent conflicts of interest or bias and ensure objective, credible test results. The lab must be free from any stake in the project outcome so its data aren’t influenced by the contractor, supplier, or project team. This isn’t automatic for every test, nor is it never required; the obligation exists where the specifications call for an independent laboratory. The requirement can apply to any material or test if the project specifications require it—such as for supplier-supplied materials or other critical tests.
