Pipe & Excavation Contracting Manual

The trench is open, the inspector is on site, and the answer has to be right the first time.

Underground utility contracting has no margin for learning on the job - a missed soil classification, an unprotected excavation, or a failed pressure test does not just cost money, it costs workers, schedules, and licenses.

This manual gives contractors, superintendents, and project managers the technical grounding to make the right call at the trench edge, the plan table, and the bid desk - every time.

Inside this book:

• Soil classification applied to real excavations - use the OSHA Type A, B, and C system the way 29 CFR 1926 Subpart P requires it, with field tests, disqualifying conditions, and competent person liability explained without ambiguity
• Shoring, shielding, and sloping - select and install timber shoring, aluminum hydraulic systems, and trench boxes using tabulated data, with the installation and removal sequences that keep workers alive
• Pipe materials, jointing, and bedding - match PVC, ductile iron, HDPE, reinforced concrete, and steel to system type and soil conditions, then bed and backfill them to hold deflection and grade for the life of the system
• Gravity and pressure system installation - set pipe to grade with a laser level, manage thrust restraint, disinfect water mains per AWWA C651, and commission gravity sewers from the first joint to the final CCTV report
• Trenchless methods from HDD to pipe bursting - execute pilot bore, reaming, and pullback operations, select the right method for the crossing, and build bore pits that meet OSHA and equipment requirements simultaneously
• Estimating, contract administration, and claims - build unit price bids that hold margin, document differing site conditions the moment they appear, and manage RFIs and change orders before they become disputes

This book is written for underground utility contractors, field superintendents, foremen, project managers, estimators, and anyone preparing for a contractor licensing examination in the excavation and utility specialty.
