The spokesman, Jonathan Harvey, said state workplace safety officials said Monday that while their investigation is ongoing and could take months, "the jobsite has been deemed safe and is permitted to reopen."
The Santa Clara County Medical Examiner-Coroner's Office identified the man as Edward Erving Lake II, 60, of Vacaville. He was an employee of Gerdau Ameristeel's Napa Reinforcing Steel facility, a subcontractor working on the stadium, Gerdau's spokeswoman Kimberly M. Selph said.
In a statement, the 49ers said their "sincerest thoughts and prayers are with the family, friends and co-workers affected by this tragedy." The team also said there were plans to have support on-site Tuesday to help workers with their emotions following the tragedy.
The stadium is in Santa Clara, about 40 miles south of Candlestick Park, which it is replacing. Construction is slated to be finished in July, and officials say the accelerated work plan involves a highly coordinated scheme to maximize efficiency and avoid delays.
Construction firm investigators also were on-scene Monday, to see what could have been done to prevent the deadly accident.
An elevator mechanic, 63-year-old Donald White, was also killed at the stadium in June when he was struck by a counterweight while working in a shaft.
White worked as an elevator mechanic for more than 40 years and was employed by Schindler Elevator Corp. An investigation into his death by the Occupational Safety and Health Administration is underway.
The stadium project is expected to open its doors just in time to host the 50th Super Bowl, in 2016, in the heart of the Silicon Valley. The airy, open stadium would have the largest lower bowl in the league, ensuring the 68,500 fans are close to the action.
The construction costs are being paid by $800 million in seat and luxury box sales, along with a 20-year, $220 million naming rights agreement with Levi Strauss and Co. announced in May.
