Prepared by the Direct Design of Buried Concrete Pipe Box Sections Standards Committee of the Construction Institute of the American Society of Civil Engineers

Standard ASCE/CI 27-17 addresses the direct design of precast concrete pipe that will be installed using jacking, a type of trenchless construction. Successful installation of pipe using jacking techniques requires that the engineer design for loading conditions both during and after installation, as well as skillful placement by the installing contractor and precise fabrication of the pipe-all topics covered in this standard.

Standard Practice for Direct Design of Precast Concrete Pipe for Jacking in Trenchless Construction covers piping intended for the conveyance of sewage, industrial wastes, stormwater, and drainage, as well as for utilities and access ways. It presents design and analysis methods that consider the interaction between the pipe and surrounding soil and/or grout envelope in order to determine the longitudinal loads that develop during jacking, as well as transverse pressure distributions and circumferential moment, thrust, and shear in the pipe wall. A procedure for calculating the required reinforcement in the pipe wall is included. Appendixes offer standard practice for manufacturing suitable pipe, managing jacking operations, and estimating the required jacking force.

This Standard, a revision of ASCE 27-00, may be used as a reference in preparing project specifications for jacking in trenchless installations, and the limits state design procedure is consistent with the procedures outlined in the AASHTO Standard Specifications for Highway Bridges . It includes updates to correlate with the latest ASTM International and American Concrete Pipe Association (ACPA) documents. It will be useful to civil engineering design professionals, consultants, owners, and transportation officials.
