TKDA is a mid-sized, employee-owned civil engineering practice established in 1910. It brings together engineers, architects, planners, and specialized experts to deliver multi-disciplinary solutions across client challenges in industrial and manufacturing, transportation, building and site development, and water markets. Headquartered in Bloomington, Minnesota, the firm operates a network of offices in Chicago, Duluth, Milwaukee, Minneapolis–St. Paul, San Bernardino, and Seattle to serve clients from coast to coast. Emphasizing collaborative, cross-disciplinary teams, TKDA seeks long-term relationships by addressing a broad range of client needs with adaptable solutions. The firm has expanded its capabilities through acquisitions in recent years, including CNAengineers in 2025 and M.A. Bielski & Associates in 2023. In a concrete recent development, TKDA partnered with the City of Porterville to design a forward-looking maintenance facility that supports the city's transition to a zero-emission fleet.
