Foundation Engineering Consultants, Inc
Mr. Affi is the founder of Foundation Engineering Consultants, Inc., in the state of California. He specializes in excavation support analysis, drilled pier foundations and sub-structural engineering software. Mr. Affi is a licensed civil engineer in California and has authored three books. He was recently awarded a U.S. patent in a new method of supporting lightly-loaded foundations and pavements on highly-expansive soils. Mr. Affi is very interested in filling the practice gap between geotechnical and structural engineers when it comes to foundations and earth retaining structures.
