The project team at Allegiant Stadium in Las Vegas has been running two races: first, a sprint to finish the $1.9-billion domed stadium in time for the NFL’s Raiders to play their first season in Las Vegas this fall, and second, staying a step ahead of the pandemic. Mortenson-McCarthy, the joint venture between M.A. Mortenson Co. and McCarthy Building Cos. that is serving as general contractor on the project, reports the 65,000-seat stadium remains on track for substantial completion in July, with the Raiders and University of Nevada Las Vegas football teams scheduled to play their first games there in August.
