The Standard Design Practice, C857, developed by the American Society for Testing and Materials (ASTM) for Minimum Structural Design Loading for Underground Precast Utility Structures, has been the criteria used by UCP to develop the UCP proprietary utility vaults in this online catalog.

UCP recommends that the suitability and application of these products be determined by a licensed Professional Engineer experienced in underground construction.
