What Drexel, Barrell & co does

Drexel, Barrell & Co. is a 100% employee-owned civil engineering and land surveying firm founded in 1949 and headquartered in Lafayette, Colorado (relocated from Boulder in 2022), with a regional office in Colorado Springs established May 1, 1973. The firm provides integrated land surveying, civil/site infrastructure engineering, water resources engineering, transportation and traffic engineering, and construction inspection services across Colorado. Over 60% of project volume originates from public-sector clients, including cities, counties, universities, school and utility districts, the State of Colorado, and federal/military installations including NORAD, Fort Carson, the U.S. Air Force Academy, and Peterson AFB. Long-tenured named clients include the University of Colorado Boulder (75+ projects), the National Renewable Energy Laboratory (50+ projects at its Golden facility), Boulder Community Hospital, multiple Colorado municipalities, and historical private-sector work for the IBM Boulder Plant.

The firm's technical capabilities center on an integrated "field-to-office-to-field" service model that provides single-source responsibility from initial design surveys through final construction inspection. Core technology includes GPS surveying (pioneered in Colorado in the 1990s with landmark applications at Pikes Peak and the I-25/6th Avenue interchange for CDOT), LIDAR surveying (including the first interior survey of the Colorado State Capitol), and traditional surveying methods integrated with modern equipment. The firm maintains survey records spanning over 150 years, including what is described as the most comprehensive collection in Boulder County, assembled by founder Frank R. Drexel during his 20-year tenure as Boulder County Surveyor. The current five-line service portfolio was completed in 1993 with the addition of transportation/traffic engineering and water resources engineering to the historical surveying and civil engineering core.

Drexel Barrell operates as a professional services firm using quote-based project billing, with no publicly disclosed pricing. The firm is structured as an Employee Stock Ownership Plan (ESOP), currently in its fourth generation of employee ownership following the August 18, 2022 transition. Revenue is generated entirely from professional services fees across a single-source delivery model, with the entire operating footprint limited to Colorado and no external capital, parent company, or private-equity involvement. Total headcount is 51–100 and the firm has completed over 25,000 projects since founding. The firm emphasizes long-term client relationships, repeat business, and locally-available integrated expertise over active demand-generation-driven growth.
