Tolerances for Cast-In-Place Concrete Buildings

Tolerances for Cast-In-Place Concrete Buildings: A Guide for Specifiers, Contractors and Inspectors was written by Bruce Suprenant and Ward Malisch, and published by the ASCC. The authors suggest tolerances that are based on as-built measurements of buildings and other structures that have performed satisfactorily. The book includes a history of cast-in-place concrete tolerances, as-built measurements that support realistic and achievable tolerances, and rational suggested tolerances based on as-built measurements. Section 1 includes the suggested tolerance language to be included in specifications. Section 2 gives extensive background information to support the tolerances in Section 1. The book will help owners, specifiers, and contractors avoid the tolerance traps that cause schedule delays, construction claims, and associated costs.

For the first time ASCC compares concrete tolerance requirements with as-built measurements of concrete structures which show that many accepted tolerances can result in schedule delays, construction claims, and avoidable costs for arbitration or litigation.
