Our name is important to us—that’s why we stand behind every contracting, commercial, and industrial construction service we perform. From pre-construction consultations to project completion, our ownership and staff are always available to address any questions, ideas, or issues you may have.
There’s a reason we’ve stood the test of time to remain a constant in the Front Range for over 80 years. There is no more dependable commercial general contractor for Denver.
2020 Star Metal Building Master Builder Award
As a commercial general contractor for Denver, we strongly believe the best ideas are developed through collaboration. Our design-build services bring you face to face with our architectural, design, and engineering staff. These meetings help everyone work together to learn your needs, business goals, and future plans to create a cohesive plan. Not only does the design-build approach bring clarity, but it also streamlines projects and reduces costs. When the Calahan Construction team takes full accountability for your construction project, you don’t have to worry about balancing communications between multiple companies and the additional fees they charge.
