NOTE:

This guide specification covers the requirements for architectural precast concrete products, that through their finish, shape, color, or texture contribute to a structure's architectural expression. These products may be custom designed or feature standard shapes. They may be manufactured with conventional mild-steel reinforcement, or they may be pretensioned or posttensioned. These products typically have more stringent requirements for dimensional tolerances, finish variations, and color consistency. Architectural precast concrete products includes wall panels, mullions, bollards, urns, railings, sills, copings, benches, planters, pavers, and other types of miscellaneous shapes.
