About EVS

Our Firm

We are EVS.

Since 1979, EVS has provided Civil and Electrical Engineering, Land Surveying and Environmental permitting assistance to customers throughout the U.S. By 1991, the company started doing civil designs for the U.S. Military and by late 2010, began working in Wind Energy. EVS entered the Solar Market in late 2014 and further grew the company until the present when over half of EVS’s work has to do with engineering the Civil and Electrical designs for the U.S. Solar Market.

Over the years, EVS has punched greater than its weight by being involved in prestigious projects such as the Minnesota Vikings’ U.S. Bank Stadium, the University of Minnesota’s TCF Bank Stadium, and numerous Light Rail and highway transit projects. As an ever improving company, EVS is committed to the success of its customers and the fullfillment of its employees. The company’s culture of respect, integrity, transparency and high ethics translates into an engineering partner who provides increasing value to every project and to an employer who has as its core, the hope that all employees grow in their careers and have fun doing it.
