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 led us to open a Colorado Springs office in 1971 and kept us busy for nearly three 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), the two projects established Drexel Barrell as first among equals in El Paso County.

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 continuous Colorado Springs presence for 48 years, we are arguably the Pikes Peak region′s most experienced civil engineering and surveying consultant.
