Covers the things a contractor should know about soils and foundations, what he can do himself, and when he needs to call a consultant. This second edition presents more information useable by smaller contractors, and less on heavy foundations which require the services of outside specialists. Assumes no previous expertise in soil and foundation behavior. Coverage begins with first principles, followed by detailed descriptions of practical applications. Part I explains what to expect from soils encountered during construction. Part II provides more specific information on soils and foundations needed by small to medium-size contractors.
