Abstract: This Reference Specification provides standard tolerances for precast concrete construction. It covers dimensional tolerances for precast concrete members used in building construction, and it covers erection tolerances for these members. This document is intended to be adopted by reference in Contract Documents. The Specifier supplements the provisions of this Reference Specification as needed by specifying projectspecific requirements in Contract Documents.
Keywords: alignment; construction; erection tolerances; precast concrete; prestressed concrete; product tolerances; reinforcement; specification.
