Obama to sign beam of One World Trade Center

With the under-construction One World Trade Center fast approaching its final height, President Barack Obama will visit the New York tower Thursday to get an update on its growth and help prepare one of the finishing touches.

Obama is expected to sign a beam that soon will be placed at the top of the tower, said Mike Pinelli, general superintendent of the Tishman construction firm.

"We're going to have our topping-out beam placed on the street" so Obama can sign it, Pinelli said. "It's typically signed by everybody on the project at some point, and then we're going to erect it shortly thereafter to signify the topping out of (the tower)."

Obama, accompanied by first lady Michelle Obama, is due to arrive at New York's John F. Kennedy International Airport in the late afternoon and at the construction site about 5:15 p.m. ET to get a briefing on the building, currently 104 stories and 1,300 feet tall - already the tallest structure in New York.
