Ground Game

Langan Tackles Engineering Challenges to Help Allegiant Stadium Re-Shape the Las Vegas Strip

The Raiders completed their relocation from Oakland to Las Vegas with a victory against the New Orleans Saints on Monday September 21. The game represented the culmination of one of the most unique and challenging professional stadium projects in recent history.

Allegiant Stadium seats 65,000 fans beneath a dome and features a retractable natural turf field along with space for tailgating amenities and parking. After initially being brought on to peer review foundation design, Langan was appointed geotechnical engineer of record, and also provided specialized site/civil services, leveraging its local knowledge of the subsurface conditions in Las Vegas and the firm’s unparalleled experience on major sports projects.

“From the very beginning, working with the Raiders organization and the design and construction team, Allegiant Stadium has been a fantastic project,” said Diane Fiorelli, Principal, Langan. “Our local team led by Jason Goff, our Project Manager in the field, helped our client and partners make critical, cost-saving decisions throughout design and construction, which also helped maintain schedule to make the opening day kick-off.”

Langan performed an extensive geotechnical investigation to obtain subsurface information at selected heavily loaded stadium column locations to optimize deep foundation design and along 20 to 45-foot tall retaining walls; provided key recommendations for street widening; conducted a fault investigation, and analyzed groundwater samples, among other key tasks. Langan’s site/civil group and BIM modeling group worked closely with other consultants to design the under-slab and perimeter wall drainage system that was integrated with all of the sub-slab utilities and foundation systems.
