Kiewit, one of North America's largest infrastructure contractors, has taken on the construction-manager-at-risk role for the redevelopment of Aspen/Pitkin County Airport, according to the Aspen Times.

The engagement puts a nationally scaled builder behind a project that has spent years working through local political and environmental review in Pitkin County, Colorado. For an airport that anchors air service to a resort economy with limited ground alternatives, the choice of delivery method signals that the county is moving from planning toward execution.

What does the construction-manager-at-risk model change?

Under a construction-manager-at-risk contract, the owner brings the builder on board during design rather than awarding work through a traditional low-bid process after drawings are complete. The contractor advises on constructability and cost as the design matures, then commits to a guaranteed maximum price for construction.

For a public airport owner such as Pitkin County, the model shifts early cost risk to the contractor and creates a single point of accountability during the design phase. It is a delivery structure commonly used on complex, phasing-constrained airfield projects where construction must continue around active operations.

Kiewit brings deep aviation-adjacent experience to that task. The firm has delivered major infrastructure programs across North America and routinely works under the operational, safety and scheduling constraints that govern work on a live airfield.

Why the contractor choice matters for Aspen

Aspen/Pitkin County Airport sits in a mountain valley with demanding operational conditions, serving a market where airline capacity is tightly contested during peak ski-season windows. Any airfield redevelopment that improves pavement condition, aircraft handling capacity or terminal-side efficiency translates directly into the airport's ability to hold and potentially grow seasonal service.

The project has also been a subject of sustained local debate over the airport's size and the types of aircraft it can accommodate, making delivery credibility a political question as much as an engineering one. Handing construction management to a firm of Kiewit's scale gives the county a partner with the balance sheet and bench strength to keep a contested program on schedule.

What comes next

With Kiewit in place, the project's next milestones will be design-phase cost input from the contractor and, ultimately, a guaranteed maximum price that will show county officials and the travelling public what the redevelopment will actually cost to build.
