A History of Success

Since 1987, Thomas & Beers has provided a broad range of structural and mechanical engineering 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 Core 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.

Principal Engineer

Matthew Heim, PE

Matthew Heim (ME, MSME) has broad industry experience in mechanical and thermal design, including extensive finite element analysis for static and dynamic mechanical performance, component strength and safety, thermal power transmission of mechanical structures, and solid modeling techniques. He has optimized structures based on strength, stiffness, and natural frequency, and has modeled dynamic system performance of diverse components for maximum performance.  He has designed and verified structural components in the offshore drilling, computer peripheral, aerospace, and consumer electronics markets.
