On August 5, Allegiant Stadium, which will become the new home to the Raiders football team in 2020, celebrated the major construction milestone of its steel structural topping out with a ceremony hosted by Las Vegas Stadium Company. In attendance were dignitaries hosted by the Raiders and Mortenson McCarthy Joint Venture, notable project partners including architect of record HNTB, design architect MANICA Architecture, project manager CAA Icon, as well as key project team members from Arup, who is providing structural engineering, facades engineering and building maintenance scope for the project. The significant milestone marks an important moment for the project, which began construction in 2018, and is slated to be the fastest designed and constructed stadium of its size once complete for the 2020 football season. 

The topping out ceremony is a major milestone for the Raiders, Allegiant Stadium and the City of Las Vegas, and would not have been possible without the tremendous efforts of our design build team, which includes MANICA Architecture, HNTB, and Arup, among others. It is amazing what can be accomplished when talented people are willing to work hard and sacrifice for a common goal. ”

A hallmark project for the state of Nevada and the Raiders, Allegiant Stadium will feature 65,000 seats, a movable field, a retractable north façade wall and a translucent cable-truss supported roof. Sharing the project team’s common objective of expediting the construction timeline, Arup conceptualized and implemented flexible design features, such as the adjustable structural connection at the cable-truss to compression ring interface, to align with the construction schedule. The Design-Build team embraced a collaborative review approach with the Clark County Department of Building and Fire Prevention to achieve the project’s phased permit goals in alignment with fast-track construction goals. 

One of the major innovative elements that Arup incorporated into the project is the intricately designed cable truss roof. A departure from the classical structural engineering solution, the lightweight cable-truss connection to the structural steel provides a significantly increased construction tolerance during the big-lift of the cables requiring high-geometric precision.

Allegiant Stadium is slated to be complete for the 2020 football season.

I am proud that our team collaboratively introduced new structural solutions to help meet the specific project challenges. We are thrilled to celebrate this monumental project milestone with our collaborative partners and we look forward to bringing this project to completion over the next year. ”
