Office Profile

In the 1960's, Charles Gates (owner of the Gates Rubber Company) retained Drexel Barrell to provide engineering and surveying for his 3,500-acre Cheyenne Mountain Ranch master-planned community at the base of Cheyenne Mountain.

This project, surveying tunnels for NORAD beneath Cheyenne Mountain, and work at Peterson AFB led us to open a Colorado Springs office in 1973. These and other projects kept us busy for decades. Together with our 1988 boundary survey, annexation plat, and zoning map of the 24,000-acre Banning Lewis Ranch (which doubled the land area of the City of Colorado Springs) established Drexel Barrell as a leader in the El Paso County civil engineering and surveying community.

We have completed numerous important projects for El Paso County, the Cities of Colorado Springs and Fountain, Fort Carson, the Air Force Academy, Peterson AFB, and hundreds of public and private sector clients.

With a Colorado Springs presence for over 51 years, we are arguably the Pikes Peak region′s most experienced civil engineering and surveying consultant.
