CASE Guide to Special Inspections

After structural steel erection has been completed, the details of the steel frame must be inspected for compliance with the construction documents. This inspection is usually best performed by the SER Concrete Inspection The requirements for Special Inspection of concrete construction cover both cast-in-place and precast concrete.
