Allegiant Stadium Construction

Project Overview

Allegiant Stadium is the home of the NFL’s Las Vegas Raiders and one of the largest entertainment venues in Las Vegas. The Mortenson | McCarthy joint venture delivered the $1.9 billion, 1.8 million-square-foot facility on-time, completing construction in 31 months and just 40 months after the NFL approved the Raiders' move to Las Vegas. The 65,000-seat stadium is publicly owned by the Las Vegas Stadium Authority. The accelerated timeline required early alignment and disciplined execution, setting a new standard for speed and scale in modern NFL stadium construction.

Delivered through an integrated design-build approach, the project brought together more than 200 partners and leveraged digital modeling from the outset to drive performance. The result is a highly flexible venue: a fixed, translucent domed roof paired with a retractable natural grass field that rolls outside the building between events, operable walls that open to a view of the Las Vegas Strip, and a fully connected fan experience.

Delivery at Speed and Scale

The project required alignment early and sustained throughout construction. When the NFL accelerated the Raiders’ relocation timeline by a full season, the schedule left little margin for error and required decisions to be made quickly and with confidence.

Work began before every variable was fully defined, making coordination across teams and disciplines critical from the outset. The team aligned design, procurement, and construction activities to move forward in parallel, maintaining momentum while managing risk.

At peak activity, more than 12,000 workers and over 200 trades were active on site, supported by a detailed project schedule managing tens of thousands of activities. The team maintained progress through disciplined planning, clear accountability, and continuous coordination across stakeholders.

Execution and Coordination

Allegiant Stadium required a high level of coordination across design, construction, and trade partners. The project team operated within a shared digital environment, using a common model to align decisions and manage complex systems throughout the build.

This approach supported more informed decision-making and improved visibility across the project, allowing teams to identify issues early and avoid rework. It also enabled the team to visualize and coordinate key elements before installation, which was critical given the scale and complexity of the design.

Throughout construction, the team focused on identifying efficiencies and managing costs without compromising quality or long-term performance. Solutions were developed in real time, with input from across disciplines, to keep the project moving forward.

Integrated Approach and Owner Alignment

The design-build delivery model created a direct connection between the owner’s vision and the execution of the project. By integrating design and construction teams from the start, the project team was able to incorporate priorities around fan experience, operations, and long-term performance into the building as it took shape.

This structure also supported transparency in decision-making. The team worked to provide clear, realistic input on cost and schedule certainty, helping establish alignment early and maintain it throughout the project.

The joint venture combined Mortenson's national sports and entertainment construction construction experience with established relationships in the Las Vegas market. This local knowledge supported coordination with stakeholders and helped navigate regional requirements as the project progressed.

Lasting Impact

Allegiant Stadium continues to serve as a major destination for events in Las Vegas, hosting professional sports, concerts, and large-scale gatherings. The venue has strengthened the city’s position as a year-round destination for entertainment.

During construction, the project engaged thousands of workers and hundreds of contractors, contributing to the local workforce and business community. These efforts supported local business development both during the build and after completion as the stadium continues to operate as a catalyst for economic activity.
