The purpose of testing is to aid in the implementation of appropriate solutions to real problems. Even when testing is performed as part of quality assurance it can be considered part of problem solving – detecting and preventing problems.
Testing can be performed as part of a conditions assessment or site survey. Construction documents and as-builts may be lost, or subsequent repair campaigns may not be documented. Testing can provide information on what is actually there.
Testing can be performed to determine the cause or measure the extent of damage. Information provided can ensure that the correct solution is specified to solve the actual problem.
Testing can be performed to verify construction, to distinguish a small problem from a big problem, and to ensure that a repair campaign won’t actually make conditions worse.
To aid in problem solving, clients should provide drawings, photographs, and identification of known materials and assemblies.
