DESIG: C 858 09 ^TITLE: Standard Specification for Underground Precast Concrete Utility Structures ^SIGNUSE: ^SCOPE:

1.1 This specification covers the recommended design criteria and manufacturing practices for monolithic or sectional precast concrete utility structures. Concrete pipe and box culverts are not covered under this specification. Also, precast concrete manholes covered in Specification C 478 are excluded from this specification.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
