ASTM C857-19 PDF Download

ASTM C857-19 is a standard practice that establishes the minimum structural design loading for underground precast concrete utility structures. It specifies the minimum live loads and dead loads to be applied when designing these structures, excluding concrete pipe, box culverts, and materials covered in Specification C478.

The purpose of this standard is to provide a standardized approach to ensure the structural integrity and safety of underground precast concrete utility structures. It is important for the user to verify the anticipated field conditions and requirements, as the design loads specified in this standard may not be sufficient in certain cases.

It is worth noting that the purchaser is cautioned to properly correlate the anticipated loading conditions and field requirements with the design loads used. This means that additional considerations beyond the minimum requirements of this standard may be necessary in order to meet the specific needs of each project.
