About West Plains Engineering

West Plains Engineering, Inc. is an engineering firm, specializing in the design of mechanical and electrical systems for all types of building environments. We have been providing high quality service to our clients for over 30 years.

Our story began in 1984, when a South Dakota School of Mines & Technology and a South Dakota State University graduate decided to start their own firm in Rapid City. Over time, we grew to include four additional regional offices in Sioux Falls, Casper, Cedar Rapids and Bismarck, all while maintaining our small business dynamic and belief that our designs are only as good as the service we provide.

Today, the West Plains team has developed a reputation for having the resources and expertise needed on most any construction or renovation project. Our professional engineers maintain active registrations in all Midwest states and have strong connections throughout the Region because this is our home. With our team members, resources and a genuine passion for engineering that dates back to our beginnings more than 30 years ago, we strive to serve our clients to the highest professional standard as a complete engineering solution center.
