STATEMENT OF QUALIFICATIONS Foundation Engineering Services, D.P.C. (FES) is located in Brewster, New York around 60 minutes north of New York City. FES provides foundation engineering and geotechnical consulting services and specializes in design, instrumentation, and testing of deep foundations. Our services have been utilized during the design, construction, and post construction phases of geotechnical projects for both public and private agencies. FES personnel are currently or recently have been involved in some of the largest federally supported projects in the USA including the Central Artery project in Massachusetts, I95/I195 improvements in Rhode Island, I287/I87 interchange in New York, and the Woodrow Wilson Bridge in Maryland/Virginia. FES personnel have strong backgrounds with commercial and academic geotechnical experience, including foundation design, construction engineering, instrumentation, and testing. Our clients include public agencies, engineers, general contractors, deep foundation contractors, architects, and developers in the US and overseas. FES personnel have a unique perspective to geotechnical consulting that is based on years of heavy/civil construction experience. This experience has allowed us to provide value engineering and construction engineering services to our construction clients and has also enabled us to provide practical and feasible foundation designs for design/build projects. FES personnel has specialized experience in deep foundation testing for capacity determination and integrity testing. This specialty has allowed our clients to re-use previously installed foundations and save costs on the overall foundation construction. In addition to these specialty services, we have, and are actively developing, our own software, hardware, and methods for improving the design and reducing the cost of constructing foundations. FES personnel have been involved in research to allow the FHWA to re-write the current code for LRFD design of deep foundations. This research has led to the development of new specifications (AASHTO LRFD Edition 17) that all US highway departments use to design their roads and bridge structures. This familiarity with and involvement with the development of the FHWA code has allowed FES personnel to remain as the forefront of LRFD design of foundations.
