Our team is comprised of reliable, responsive and flexible engineers. Thomas J. Principe, III, PE leads the team with many years of construction experience. This experience, coupled with his expansive engineering knowledge, allows Thomas to design both practically and economically. He not only understands the intricate working details of engineering machines, but also understands how a system will function in real space while working with site-specific conditions. This attention to detail and practicality ensure that his designs are always constructible within the field.

Our engineers are trustworthy, knowledgeable, and always seek the same goals as our clients. This allows us to overcome challenges presented throughout all aspects of the engineering process and ultimately results in a solution that meets the client’s needs. To help us achieve this outcome, we use the latest design methods in order to maximize a sites potential and maneuver through any obstacles, whether it be site constraints or strict regulations. All this is done while additionally keeping in mind the cost of a project, as budgetary concerns are just as important to us as they are to our clients.
