Abstract:
As-built measurements are used to determine if concrete construction is in compliance with specified tolerances. But concrete members move after concrete has hardened and most of these movements occur over a period of months or years. The article discusses requirements of ACI 117-10 for surface measurements of slabs and suspended slabs, and asks why similar timing restrictions are not used for other compliance measurements.
