Engineering | Consulting | Surveying

SGM has been contributing engineering solutions to Colorado communities for several decades. As a multidisciplinary 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, Durango, 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 100 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.’


2023 Steve Westhoff Scholarships Are AWARDED!

In September 2001, SGM was saddened by the death of Steve Westhoff, a field engineer and SGM employee of two years. Steve’s integrity, humor, and technical knowledge inspired SGM and many clients. In 2002, SGM renamed its scholarship in honor of Steve and the qualities he embodied as a person and engineer.

 The Steve Westhoff Scholarship is available to graduating high school seniors planning to attend a college/university to pursue studies in civil engineering (such as structural, traffic/transportation, water, wastewater, and environmental engineering), mechanical and electrical engineering, or surveying.


Out of the 25 applications we received, six scholarships were awarded. Congratulations to the 2023 Steve Westhoff Scholarship presented by SGM! Click here to see the recipients.
