Construction work at Allegiant Stadium, the future home of the Raiders NFL American football franchise in Las Vegas, remains on budget and on schedule with about three-quarters of the project having been completed, the company spearheading the development has claimed.

Building work at the 65,000-seat stadium, which signed up its naming-rights partner in August, is on track to meet the “substantial completion deadline” of July 31 next year, according to Mortenson Construction, which is collaborating with McCarthy Building.

The two companies have worked with more than 70 subcontractors since groundreaking in November 2017, with Manica Architecture designing the $1.9bn (£1.48bn/€1.72bn) stadium.

Eric Grenz, Mortenson’s vice-president of operations for sports and entertainment, told Construction Dive that the stadium’s structural steel has been installed, with the curtain wall of black glass currently being layered on the exterior as the roof is raised.

“There’s a lot more going on than what you see from the outside right now,” said Grenz, who added that the final lower-level precast section was erected earlier this month.

Nearly 900,000 cubic yards of dirt has already been removed from the 1.75 million-square-foot site, with 12 miles of concrete shafts drilled in, along with miles of piping. The stadium will ultimately comprise 28,000 tonnes of steel, 105,000 cubic yards of concrete and 482,000 structural bolts, underpinning a stadium that will have a retractable pitch and four rolling doors to frame a 90-foot by 200-foot view of the Las Vegas Strip.
