Architects Asked To Report Suspicious Requests To FBI

"Concerned about the distribution of unusually detailed building information, the American Institute of Architects plans to alert its 70,000 members today to "immediately report any suspicious requests to the appropriate local F.B.I. field office...architectural and engineering firms have reported 'requests for building plans that, in light of the Sept. 11, 2001, attacks, appear unusual due to the structures identified in the requests or the type of information solicited.'While institute officials would not be more specific, it is understood that some requests involved airport terminals and towers, federal office buildings, parking garages and museums, and that the details sought sometimes included mechanical, electrical and structural systems."
