Drexel Barrell has been continuously serving our Colorado clients for 77 years. To our knowledge, this may set the record for longest tenure of any Colorado surveyor / civil engineer (at a minimum, it certainly puts us into the top two or three!). During this time, we have completed more than 25,000 projects for our clients across Colorado and neighboring states.

Because we are both surveyors and engineers, our company is able to provide complete services, from field to office to field. Our surveyors collect existing ground, infrastructure, and boundary information upon which our engineers prepare design plans, specifications, and construction cost estimates. Our surveyors stake the design improvements, ensuring a quality product. This continuous feedback loop provides quality control checks and balances from multiple angles and perspectives.
