About Us


Since 1972, Donlar Construction has been managing and constructing projects throughout Minnesota. Our passion is doing high quality, hands-on work. In fact, most of us picked up tools at a young age and have used them all our lives. As a result, our team has the talent, commitment, and knowledge to effectively manage every aspect of a construction project. That makes us more than project superintendents and managers. We are also skilled craftsmen with a deep understanding of construction. Our clients can relax, knowing they will get high value results with minimal stress.

Construction might be our passion, but safety is our top priority. Safety is emphasized in everything that we do, and we utilize an aggressive and comprehensive safety program on all our construction projects. We have recently become a level one member of the CHASE Partnership, in an effort to further improve the safety of our staff and all people on site. Our commitment to safety has led us to 1.2 million hours of no loss time and counting!


Throughout the project, Donlar Construction showed diligence dedication and professionalism to finish work on time and in handling difficult situations when they arose.
