Marty Hudson, Ph.D., P.E., G.E.
President and Principal Geotechnical Engineer
Martin (Marty) Hudson has over 30 years of industry experience covering a variety of building types, sizes and market sectors. Dr. Hudson is a Licensed Civil and Geotechnical Engineer. He obtained his B.S. and M.S. degrees from the University of California, Los Angeles and Ph.D. in civil engineering from the University of California, Davis.
Dr. Hudson has worked as geotechnical engineer of record on some of the largest projects in California history, including the Wilshire Grand tower, Ronald Reagan UCLA Medical Center, the New Century twin tower development, and the LADWP Headworks Reservoir. He also has voluminous experience with commercial building and stadium development of all sizes throughout the United States. He has worked as one of the plan check reviewers on behalf of the City of Inglewood for the geotechnical aspects of the SoFi Rams Stadium. For several major transit projects, including the Los Angeles Metro Purple Line Westside Extension, he has served as Project Manager for the geotechnical and environmental investigations. He has extensive experience with deep excavations, shoring, soil nailing, MSE walls, ground improvement, shallow and deep foundations including driven piles, drilled shafts, caissons, and micropiles. He also has extensive experience with ground motion studies on many high-rise buildings, reservoirs, subway stations and tunnels, and hospital buildings, including base-isolated and damped structures. He is a member of the Hospital Building Safety Board for the State of California, an Honorary Member of the Structural Engineers Association of Southern California (SEAOSC), and serves on the seismology committee of SEAOSC. He has served on the Board of the American Society of Civil Engineers Los Angeles Branch Geo-Institute and on the Board of SEAOSC. He also teaches courses on foundation engineering at the UCLA Henry Samueli School of Engineering and Applied Science. He has dozens of publications on seismic and geotechnical engineering topics.
