CTLIThompson has a long history in Summit County — Founder Bob Thompson led the groundwork for the first lift towers at Keystone Resort and Copper Mountain, thanks to his part-time gig as a ski instructor. This office has been operating in the Summit County area since 2014. The office’s early projects were primarily geotechnical services for residential, commercial and municipal projects, including septic and pavement design. Summit County has further expanded its capabilities by adding an environmental specialist and structural engineering.
