Empirical qualified engineers regularly undertake inspection of pre-cast concrete and cast in-situ concrete elements as part of quality control checks either on site or at the pre-cast factory.

This can include the below: -

• Monitoring of quality control and workmanship including placement/curing process.

• Checks on compaction using visual examination and non-destructive test methods.

• Monitoring of maturity of the elements being cast.

• Checks on accurate placement of reinforcement and post tensioning following casting for example using GPR to check for displaced post tensioned tendon profiles.

• Reinforcement checks on placement and concrete cover checks.

• Non-destructive testing such as cover meter, Schmidt hammer, UPV, tomography and GPR scanning.
