ASTM C891-20

Standard Practice for Installation of Underground Precast Concrete Utility Structures

ABSTRACT
This practice covers the procedures to be followed in the planning, site preparation, and installation of underground precast concrete utility structures. The installation area shall be surveyed using the workprint and a checklist to identify the work to be done and to determine that the plans are correct. Permits required to do work in accordance with the detail plans shall be secured before starting the job. All permits or a record of the permits shall be retained on the job for immediate reference. Safety requirements for construction shall be in accordance with all federal, state, and local regulations. Shoring for construction shall be in accordance with all federal, state, and local regulations.
SCOPE
1.1 This practice covers the procedures to be followed in the planning, site preparation, and installation of underground precast concrete utility structures. Concrete pipe and box culverts are not covered under this practice. Also, precast concrete manholes covered in Specification C478/C478M are excluded from this practice.  
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.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
