Richard M. Simon, P.E., Ph.D.
Senior Principal Engineer

Dr. Simon started his profound career as a professional engineer after receiving his bachelor's degree from Cornell University and Ph.D. from Massachusetts Institute of Technology. With over 30 years of experience in geotechnical engineering, Dr. Simon has completed geotechnical engineering design services on hundreds of transportation and building projects supported on a variety of shallow and deep foundations. His expertise includes precast concrete piles, mini-piles, drilled piers, pressure-injected footings (PIF's), steel H-piles and timber piles, design and installation of deep foundations adjacent to critical structures, and design of structures to resist earthquake induced forces and displacements and soil liquefaction. Dr. Simon also has specific expertise and experience in stage preloading of embankments and foundations to control settlements and stability.
