Connecting Communities
through Water

At Calibre, we love water! We appreciate the significant impact that water has on the environment, the community, and the lives of the people we serve.  


Calibre is looking for a passionate Water Resources Engineers to add to our Water Resources Division!


Supporting Waterways

We take water resources seriously. We endeavor to think creatively. 


Calibre is passionate about integrating rivers into communities in a real, tangible way. We believe in the power of recreation and access, as well as the principles of resilient design, ecological preservation, and habitat restoration. We understand that waterway function and channel geomorphology are cornerstones of watershed planning, and we strive to design so that waterways can expand and contract with their natural cycle. We respect water as both an attraction and a resource. 

We take pride in our ability to provide ingenious, sustainable, and astute water resource designs.

Our experience includes restoring the South Platte River through central Downtown Denver; stabilizing and restoring Tollgate Creek in Aurora and Jackass Gulch in Littleton; and mitigating fatal, disastrous flooding within the South and South Central Basins in Englewood. We have firsthand experience responding to bank collapses and infrastructure failures, and we have designed interactive water play features to encourage human connection. Our designs account for the existing and future condition of a waterway and overall watershed, and we strive for innovation and excellence. 

Founded in 2000, Calibre is a Service Disabled Veteran Owned Small Business (SDVOSB) with a mission to support and serve our communities through high-calibre civil and structural engineering.
