Do you specialize in or sometimes delve into geotechnical testing, observation and documentation? Our indispensable ASCE field manual has been newly updated and expanded. Thousands of soil technicians and geotechnical engineers have used the original in-depth guide to help them conduct common laboratory and field tests, classify soil accurately, interpret project recommendations and document the entire construction-monitoring process. The guide updates areas on deep foundations, shallow foundations, retaining walls, loss prevention and more. Sample test questions appear at the end of every chapter, and a comprehensive case study presents each step of a sample project, from site investigation and lab work through construction and documentation.
