What does "as-built thickness" refer to during inspection?

Explanation:
As-built thickness is the actual thickness of the fireproofing material as it exists after it has been applied and finished in the field, measured on the installed surface. This in-place measurement shows what is there on site, not what was planned or drawn. It’s used to verify compliance with the required thickness in the project specifications; if the measured value is too thin, remediation or rework is needed, and if it’s thicker than allowed, it’s checked against tolerances and may still be acceptable within those limits. This concept is distinct from the designed (intended) thickness, the substrate’s thickness before application, or any finish coats on other surfaces like drywall.
