A History of Success

Since 1987, Thomas & Beers has provided a broad range of structural engineering consultation services. Computations range from the complexities of time-history nonlinear transient dynamic analyses to relatively simple (though often critical) hand calculations. Thomas & Beers articulate analytical results that are often just the starting point of finding appropriate engineering solutions. Proper evaluation of results, based on sound engineering judgment and experience are just as important as the results themselves.

Our Management Team


David Thomas, PE

David Thomas (CE, MSCE) specializes in structural engineering, design, and finite element analysis, with particular expertise in evaluating mechanical components used in structural applications. He has developed strength and failure criteria for use in evaluating finite element analytical results in determining component load ratings. He is proficient in dynamic analyses of structures, especially seismic evaluation of offshore oil platforms and appurtenances using time history, response spectrum analysis, and quasi-static techniques. He is also skillful in general dynamic evaluations of structures, including natural frequency determination, impact analysis, vibration isolation, and shock loading. Dave has extensive experience in using finite element analysis in conjunction with full-scale testing to develop component prototypes into viable end products.


Anthony Ronca, PE, SE

Anthony Ronca (CE, MSEM) is a top-performing professional engineer with over 25 years of experience in oil & gas, heavy industrial, institutional, commercial, residential, studio, DSA, OSHPD, aircraft, and research & design. He is a licensed professional engineer in 14 states and has technical design experience in steel, concrete, masonry, wood, miscellaneous metals, and advanced composite materials. His analysis experience includes blast dynamics and linear and non-linear static and dynamic analyses. He specializes as a liaison between concept and construction with the ability to ensure efficient fabrication and constructability from complex analysis and design. Anthony has experience in feasibility studies, conceptual design, design development, detailed design, fabrication, construction, construction support, constructability studies, value engineering, and peer review. He has specialty experience in blast retrofit of existing DOS facilities, major motion picture full-scale sets and studio retrofit, DOD weapon effects test structures, and aircraft structural analysis.


Rick Beers, PE, SE

Rick Beers (CE, MSCE) has particular expertise in structural engineering, design and analysis of offshore oil and industrial facilities, including industrial processing plants, petroleum facilities, material handling equipment, and offshore oil platforms. He is proficient in steel design and the application of finite element analysis to traditional oil-field and general industrial structures and is knowledgeable of offshore oil drilling and production system equipment including topside and subsea components. Rick has developed extensive experience working with owners to effectively integrate structural engineering requirements into their facilities, including design, cost optimization, project management, field inspection, structural modifications, and safety requirements. He is experienced with the American Petroleum Institute and the American Institute of Steel Construction codes as they apply to structural engineering.
