Professional Experience

Forensic Engineering:

Director of a research project for the Electric Power Research Institute (EPRI) to develop an improved design methodology for laterally loaded drilled piers. The project involved 14 prototype tests throughout the U.S., and extensive analytical studies including three-dimensional finite element analysis.

Presented nationwide seminars to utility engineers on Laterally Loaded Drilled Pier Design.

Development of a state-of-the-art loading agenda for transmission structures for Pennsylvania Power & Light Company.

Director of a study to develop soil and rock design parameters, using pressure meter testing, for foundation design of a 500 kV transmission line in eastern Pennsylvania for Pennsylvania Power & Light Company. The project included development of a design methodology for laterally loaded drilled piers.

Director of a subsurface investigation and design of an under-drain system, a sedimentation pond, and cut and fill slopes for Electric Power Research Institute's Coal Cleaning Test Facility near Homer City, Pennsylvania.

Additional geotechnical engineering experience includes development of a design guide for foundations of electrical transmission poles; stability analyses of fill embankments and natural slopes for the design of fly ash disposal areas and for remedial dam construction; and numerous bearing capacity and settlement studies.

Additional structural engineering experience includes experimental investigation of the buckling strength of spherical shells; static stress analysis of complex plate and shell structures; development of analytical methods for predicting the behavior of steam turbine components; thermal and structural analysis of a deteriorated concrete dome owned by Fox Chapel Authority; and development of finite element computer codes for static stress analysis of linear and nonlinear solids.

Lectured in engineering graphics, fluid mechanics, and soil mechanics at Lehigh University. Taught a five-week graduate course in deep foundations at Carnegie Mellon University.
