The teen apparel retailer will relocate its headquarters from Warrendale, beginning in spring 2007, following additional construction and interior finishing of the six-story Quantum II building. It will retain the existing Warrendale facility and expand it for use as a data, distribution and logistics center. A call to the retailer was not returned by deadline.

The locally based Soffer Organization developed Quantum II in late 2003 as part of Soffer's 34-acre master-planned, mixed-use development that includes a 330,000-sf lifestyle shopping center. All are within the 123-acre former LTV Steel site, which the Urban Development Authority of Pittsburgh acquired following the plant's closing in 1993. The state provided a nearly $2.3-million low-interest loan to American Eagle to acquire the building.

"We have simply outgrown our current facility," says Jim O'Donnell, CEO of American Eagle, in a statement. "Our new headquarters, together with our existing Warrendale location will allow us to provide the best possible work environment for our associates and support our continued growth and expansion."
