(Practice)Standard Practice for Installation of Precast Reinforced Concrete Monolithic Box Sections for Culverts, Storm Drains, and Sewers
Standard Practice for Installation of Precast Reinforced Concrete Monolithic Box Sections for Culverts, Storm Drains, and Sewers
SIGNIFICANCE AND USE
This practice is useful as a reference by an owner and the owner’s engineer in preparing project specifications.
SCOPE
1.1 This practice covers the installation of precast reinforced concrete box sections cast monolithically and intended to be used for the conveyance of storm water, industrial wastes and sewage, and for passageways.
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.
