Summary of experience in professional-engineering practice...
Dr. Horvath has more than 39 years of broad, extensive, practical experience in geotechnical engineering from his active
participation in hundreds of projects involving geotechnical investigations for all types of on-land structures as well as
shallow-water marine facilities such as piers and bulkheads. Over the years his experience and direct responsibilities have
covered all project phases from field inspection and office engineering to client contact and project management.
Representative commercial projects include high-rise buildings and hospitals, primarily in the northeastern United States.
Dr. Horvath has particular experience in the analysis of mat foundations and use of controlled blasting for rock
excavation in urban environments. Industrial projects include a wide variety of chemical production, metals production,
petroleum handling and refining, and solid-waste-to-energy facilities in the United States, Caribbean, and Venezuela. Dr.
Horvath has particular experience with the behavior of large-diameter tanks on grade, including geothermal analyses of
ground freezing and thawing, as well with shallow-water marine facilities.
At the present time, Dr. Horvath provides a wide spectrum of professional engineering consulting services in the specialty
area of geotechnical engineering. Typical design-related assignments include projects requiring high-level analytical
assistance with state-of-art or complex problems. In particular, in recent years Dr. Horvath has served as a consultant
on numerous projects where expanded polystyrene (EPS) geofoam was used for lightweight fill and other functional
applications. Particularly notable in this regard was his long-term, multi-year involvement in the world-famous 'Big Dig'
Interstate highway project in Boston, Massachusetts. This project led to several cost- and time-saving innovations and
technological breakthroughs in EPS-geofoam geotechnology, all of which were shared with the public through several
scholarly publications. Dr. Horvath has also had considerable experience with grass-roots technology transfer to develop
EPS-geofoam geotechnology in new and emerging markets, both domestic and international.
Dr. Horvath also provides independent, experienced review and evaluation of geotechnical design or construction
problems that require either value engineering (VE) or forensic study. This includes services requiring either applied
research, or expert opinion and in-court testimony in legal proceedings. Depending on project scope and client and
contractual needs, Dr. Horvath's services are available either directly through his sole proprietorship, John S. Horvath
Consulting Engineer, or through his long-time association with Heller and Johnsen, a full-service geotechnical engineering
consulting firm located in Fairfield County, Connecticut.
