Our Process

Pre-Design

The pre-construction phase is one of the most vital elements of a new building project. Before breaking ground or drawing blueprints, our in-house architects and designers consider your budget, operational requirements, and plans.

As the longest operating Denver design–build company, we have a vast knowledge of the Front Range and each region’s specific permitting and zoning requirements.

Our operations team will provide you with the resources needed to plan a successful design–build project, including:

  • Investment analysis
  • Site feasibility reviews
  • Pre-construction coordination
  • Budgeting estimates

With a detailed project plan, we find avenues to optimize your project and save you money all while using industry-leading procedures and high-quality materials.

Behind the scenes, our staff conducts onsite surveys to ensure your project complies with local requirements and addresses any climate or topography issues.

Design–Build

We’re a premier Denver design–build company because of our quality workmanship. After we confirm your site is suitable for construction and the blueprints are finalized, our project managers, engineers, and general contractors can begin making your building goals a reality.

With us overseeing your entire design–build project, there’s no need to wait for third-party providers. Our team starts your construction process according to schedule and makes sure it stays within your budget and timeframe.

Plus, our project managers continually monitor your project to ensure it meets your standards. Throughout each phase, we guarantee high-quality craftsmanship and materials to deliver a finished project you can be proud of.

“Calahan Construction Services has a well-grounded team who work hard and understand our business. While they offer the typical architectural and construction skill sets, they also understand and have valuable real-world experiences inside the box, which adds considerable value for an owner.

Calahan has been very consistent in its project approach. They are careful in their planning, management, and organization of the project. And while the process is structured, they are also flexible and responsive to project changes.

I’ve also found Calahan’s people to be highly focused on value. They produce the right amount of deliverables without adding drawings or specifications that aren’t needed. They are mindful of budgets and pride themselves on delivering against budget.”
