Since graduating from SUNY Buffalo with a Bachelor of Science in Civil Engineering in 2000, Andrew Willingham has been providing engineering services throughout the Hudson Valley. Fulfilling a long awaited aspiration, he founded Willingham Engineering in early 2014.

In the early stages his career, Mr. Willingham was intricately involved in the design and permitting of large, complex land development projects. Stormwater, grading and road design were his early strengths, using his design abilities to maximize the development potential of land, meet regulatory requirements while minimizing the environmental impacts. Later in his career, he gained significant experience reviewing projects on behalf of municipalities and citizen’s groups to ensure code requirements are abided by, engineering standards are met, and environmental resources are protected. Today, he has found what he believes is a balanced approach between necessary land development projects and meeting environmental objectives.

Mr. Willingham is proud to have been intricately involved in the design, permitting and construction of several public improvement projects that provide recreation and benefit the community. Throughout his career, he has gained experience in nearly all facets of land development, which include waste-water treatment design, small bridge design, construction administration, public works bidding, hydrologic/hydraulic modeling, potable water treatment, flood mitigation, SEQR review and GIS mapping. He has also developed an extensive contacts network of the highest quality professionals in related industries that include architects, surveyors, land use attorneys and realtors. He can assist or guide you through virtually any land development project or issue.
