Over 45 Year History

CWSTRUCTURAL Engineers traces its roots back to Doug Loos, Structural Engineer, who began his practice in the area as a principal of Loos & Traeholt Associates in the mid 1960’s. In 1993, Loos & Traeholt split and the subsequent merger between Doug Loos, P.E., Chris Wentz, P.E., and Jim Heyer, P.E. led to the formulation of Heyer & Loos Engineering, Inc. Heyer & Loos Engineering has grown significantly changing its name to CWSTRUCTURAL Engineers in 2006. CWSTRUCTURAL Engineers is now practicing throughout the upper Midwest including North Dakota, South Dakota, Minnesota, Montana, Wisconsin and Wyoming.
