The fire was a small one and never progressed to the point where it posed a threat to life or property, but its location on the site of the Sept. 11 attacks made it anything but routine.
The New York City Fire Department said it got the call for help at 7:15 a.m. Workers at the unfinished tower used fire extinguishers to put out the burning plywood themselves, but firefighters were still on the scene wetting down the area an hour later.
Pat Foye, executive director of the Port Authority of New York and New Jersey, which owns the unfinished skyscraper, said there were no injuries or structural damage and that construction work hadn't been halted.
The skyscraper is already over 1,200 feet high, with a few hundred feet more to go until it reaches its full height. President Barack Obama is scheduled to visit the tower on June 14 to get a briefing on construction.
