Raiders roof delay raises concerns

The Raiders NFL American football franchise does not believe a delay in installing the new roof at the under-construction Allegiant Stadium in Las Vegas will put back the completion date for the project despite concerns raised by an independent monitor, according to a report by NBC Sports.

In November, Mortenson Construction, the company spearheading the development, claimed that the project was 75 per cent complete, with construction work firmly on track for the anticipated July 31 opening, with the first event scheduled for August 16.

However, the Las Vegas Review Journal reported that the translucent roof is now unlikely to be in place until some point in May, several months after it was supposed to be fixed in.

Independent monitor Grand Canyon Development Partners, which previously suggested that the issue is with the cable net that will lift the roof, has now said that weather conditions will play an important role in the coming weeks, with parts of the stadium interior left exposed to the elements.

“Because of the delay in the overall building enclosure, there is the possibility of weather damage as more finish work is put in place,” the monitor said.

“Our assessment is that the TCO (temporary certificate of occupancy) date may be in jeopardy if weather (rain) causes damage to interior finishes. Of the many possible situations and potential delays that a project of this size and complexity can experience, the cable net delay is one that attracts attention because of its distinctiveness.”

The cable net was prepared last summer, but Grand Canyon stated that work “was suspended pending resolution of challenges created as a result of overstressing the stadium’s structural members”.

The Las Vegas Review Journal added that five engineering firms have worked on modifying the system.

The Raiders’ lease agreement with the Oakland Coliseum includes an option for an additional season in 2020, but the team is focusing on playing the campaign at its new $2bn home, having said goodbye to fans in Oakland in December.

The issue will be on the agenda when the Las Vegas Stadium Authority meets later this week to discuss the project’s progress.
