This item is a typescript that provides a highly technical and detailed instructional guide to the field application of the Armco Jacking Method, a system of trenchless culvert installation developed by the Armco Culvert Manufacturers Association. Contents include a series of reports on completed jobs in a variety of locations including New York, Wisconsin, Tennessee, and the western plain states of Oklahoma, Kansas, Iowa, and Nebraska. Culverts provide passages for groundwater flow, typically beneath railways and roads; this trenchless system provided a solution to the problem of disrupting service and access via traditional open-trench evacuation.

The manual contains photographs showing installations, equipment, laborers working, preparatory operations, and procedures. The blueprints show fabrication pipe for jacking or field riveting, construction details, arrangement of jacking timbers, special shields for outside of pipes, and the reinforcement band.
