WASHINGTON, DC-A high-ranking FBI official said that from the moment the Sept. 11 terrorist attacks began, its Hoover Building was outdated.

At a meeting last week with interested developers, FBI Assistant Director Patrick G. Findlay detailed its requirements for its new headquarters and why the federal government is looking to swap the J. Edgar Hoover Building on Pennsylvania Avenue for a new consolidated headquarters, according to the Washington Post.

The agency’s current headquarters houses only 52% of its headquarters staff. Others are housed at offices in Quantico, VA and Clarksburg, WV.

Findlay said the FBI is looking for a 2.1-million-sf headquarters on 40 acres to 55 acres for 11,000 employees. “

Responses to an initial search for private partners are due March 4. The Senate passed a resolution in 2011 supporting a site of up to 55 acres within two miles of a Metro station and 2.5 miles of the Beltway, but the House has never taken corresponding action. See story in the Washington Post.
