Delta 3 Engineering was founded in November 2003 by Dan Dreessens, Bart Nies, and Scott Chyko, whom are all professional engineers with over 60 years of collective experience in the engineering field. The three founders of Delta 3 Engineering are not just the owners of the company, but are also the project managers of the company as well. They oversee all or part of every project that Delta 3 Engineering completes.

At the inception of Delta 3 Engineering, there were a total of five employees at a location in an undeveloped suite in the Platteville Business Incubator (PBII) building. As the company developed and its list of clients grew, the need for more space and employees was necessary. In 2006, Delta 3 Engineering moved to a larger suite in the PBII building to accommodate its growing staff and larger clientele base. This larger suite was designed to accommodate up to 14 employees, which was reached by 2009. The continued demand for quality engineering services by existing and new customers led to the hiring of additional employees and the need for more office space, leading to the purchase of the former Platteville Convention Center. This new facility, which opened in May 2011, has allowed Delta 3 Engineering to continue to grow.  In 2014, Delta 3 Engineering purchased Southwest Design Associates, which had been in business since 1977.  Delta 3 Engineering continues to assist and provide its clients, current and new, with the quality engineering and architecture services that they have come to expect.
