Delta 3 Engineering, Inc. is a full-service consulting engineering firm located in Platteville, Wisconsin, specializing in civil and municipal engineering, structural engineering, building and facilities design, grant writing, planning, surveying, and land development services. It was founded in November 2003 by Dan Dreessens, Bart Nies, and Scott Chyko with Dan and Bart the current principals (Scott retired in 2022). The current principals of Delta 3 Engineering are not just the owners of the company but are also the project managers of the company as well. They directly oversee all or part of every project that Delta 3 Engineering completes.

At the inception of Delta 3 Engineering, there were a total of three employees located in an unfinished suite in the east end of 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 on the west end of 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. In May 2011 Delta 3 Engineering moved its office to this location. Additional growth has also led Delta 3 Engineering to open a second office located in Dubuque, Iowa’s Millwork District in 2019 to better serve its Iowa-based clientele.

Over twenty plus years Delta 3 Engineering has worked on a wide variety of projects in Southwest Wisconsin that has given them the experience that a community such as the City of Platteville requires. From a simple review of a site plan to the design of a highly complex wastewater treatment facility, Delta 3 Engineering has provided its clients with practical, innovative, and cost-effective solutions. Our success can be attributed to the following three concepts: a “common-sense approach” to each project; the communication skills of our project managers and engineers; and teamwork.
