SGM has been contributing engineering solutions to Colorado communities for several decades. As a multidisciplinary civil engineering, surveying, and consulting firm our business philosophy is to serve as partners to our clients while contributing to their success. SGM is headquartered in Glenwood Springs, CO with additional offices in Gunnison, Aspen, Meeker, Salida and Grand Junction.

SGM is involved in engineering projects that affect peoples’ daily lives – from the roads we drive on to the water we drink. SGM serves as the engineer-of-record for many cities, towns and special districts throughout Colorado and has long-established relationships with attorneys, land planners, architects, developers, landscape architects, geotechnical engineers and construction companies. We have extensive knowledge of applicable federal, state and local regulations. Our knowledge, relationships and experience allow us to provide the right solutions for a wide range of civil engineering and surveying projects. As the largest Western Slope engineering firm, our clients have come to appreciate the large-firm resources we are able to deliver with small-firm, personalized service.



We’re proud to be the largest full-service engineering firm in Western Colorado. Our seasoned staff of 80 possesses the diverse technical skills required to address all project challenges. From the site development survey to the initial/final design to ensuring the project is built to specification–we have you covered.




Since 1986, our success has been built upon three key tenets: building deep and strong client relationships, understanding client’s inherent uniqueness, and assembling the best talent for the team. In fact, for many Western Slope communities, SGM has been trusted to design and oversee the construction of their largest capital expenditures.




At the heart of every SGM employee is the spirit and willingness to invest time in enhancing their community. From individual and group volunteering efforts to board leadership, our employees truly embody the essence of ‘giving back.’

SGM is very proud of our efforts to lead the preparation of the Colorado Basin Implementation Plan, one of eight plans making up Colorado’s first Water Plan. As the lead consultant, SGM prepared the Colorado Basin Implementation Plan for the entire Colorado River Basin.

We created a process that engaged citizens from throughout the Basin (Summit, Grand, Pitkin, Eagle, Garfield and Mesa Counties) through 80 public meetings to ensure that public input and concerns were incorporated.  This process was integral in creating a comprehensive list of over 400 projects and policies identified to meet the supply water needs in the Colorado Basin up to the year 2050.

It was the first time that a framework of a water model was prepared for the Colorado Basin, incorporating the water needs and water conservation practices of all water providers into one document.
