The former AT&T Long Lines Building at 33 Thomas Street is a 550 foot (167.5 meter) tall skyscraper in the Borough of Manhattan, New York, United States. It stands on the east side of Church Street, between Thomas and Worth Streets, in the Civic Center neighborhood of New York City. The building is an example of the Brutalist architectural style with its flat concrete slab facade. The building is a telephone exchange or wire center building which contained three major 4ESS switches〔 used for interexchange (long distance) telephony, two owned by AT&T〔Cylex Business Directory, 33 Thomas Street, owned by AT&T, (directory listing ), Accessed April 2, 2013〕〔33 Thomas St, New York, NY 10007, owned by AT&T, (Yahoo listing ), Accessed April 2, 2013〕 and one formerly owned by Verizon (decommissioned in 2009).〔Verizon, December 8, 2009, (Retirement and Removal of Verizon Broadway 4ESS Tandem (NYCMNYBW21T) ), Accessed April 2, 2013, ...

The CLLI code for this facility is NYCMNYBW. ==Design== The Long Lines Building was designed by architect John Carl Warnecke and completed in 1974. As it was built to house telephone switching equipment, the average floor height is 18 feet (5.5 meters), considerably taller than in an average high-rise. The floors are also unusually strong, designed to carry 200 to 300 pound per square foot (10 - 15 kPa) live loads.〔(【引用サイトリンク】title=AT&T Long Lines Building )〕 The exterior walls are precast concrete panels clad with flame-treated textured Swedish granite faces. There are six large protrusions from the rectangular base which house air ducts, stairs and elevators. There is a series of large, protruding ventilation openings on the 10th and 29th floors. William H. Whyte claimed that it features the tallest blank wall in the world.〔, p. 76〕 It is often described as one of the most secure buildings in America, and was designed to be self-sufficient and protected from nuclear fallout for up to two weeks after a nuclear blast. Its style has been generally praised, with the ''New York Times'' saying it is a rare building of its type in Manhattan that "makes sense architecturally" and that it "blends into its surroundings more gracefully" than any other skyscraper nearby. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「33 Thomas Street」の詳細全文を読む スポンサード リンク
