Black Mountain Excavation (BME) was founded in 2020 by Dalston Zimmerman with a clear mission: to build a company that prioritizes its employees just as much as its clients. Guided by that philosophy—and driven by relentless determination—Dalston has rapidly grown BME into one of Colorado’s fastest-growing excavation contractors, trusted on some of the state’s largest and most complex projects.
Under his leadership, BME has successfully expanded operations into four additional states, consistently delivering exceptional results and dependable execution for every client. What truly sets BME apart is its leadership—Dalston remains one of the most hands-on owners in the industry, deeply involved in both the field and the people who make the work happen.
His passion, creativity, and commitment to excellence continue to shape BME’s culture and performance, paving the way for the future of excavation.
