USA2014/2 - UPMC building in Pittsburgh
U.S. Steel Tower, also known as the Steel Building (formerly USX Tower) is a 64-story, 256.34 m (841.0 ft) skyscraper with 2,300,000 sq ft (210,000 m2) of leasable space at 600 Grant Street in downtown Pittsburgh, Pennsylvania. It is the tallest skyscraper in Pittsburgh, the fourth tallest building in Pennsylvania, and the 41st tallest in the United States.
The tower's original name when completed in 1970 was the U.S. Steel Building and was changed to USX Tower in 1988. The name was finally changed back to the U.S. Steel Tower in January 2002 to reflect U.S. Steel's new corporate identity (USX was the 1990s combined oil/energy/steel conglomerate). Although no longer the owner of the building, U.S. Steel is one of the largest tenants. The building is located at 600 Grant Street, ZIP code 15219.
In the planning stages, U.S. Steel executives considered making the building the world's tallest, but settled on 840 ft (260 m) and the distinction of being the tallest building outside New York City and Chicago. However, it eventually lost even that distinction to newer buildings erected across the United States. Prior to 1970, the tallest building in Pittsburgh, at 44 stories, was the Gulf Building. Now an office complex known as Gulf Tower, it was the original headquarters of the Gulf Oil Corporation. in 2014, the elevators were modernized by "Schindler PORT"
The U.S. Steel Tower is architecturally noted for its triangular shape with indented corners. The building also made history by being the first to use liquid-filled fireproofed columns. U.S. Steel deliberately placed the massive steel columns on the exterior of the building to showcase a new product called Cor-ten steel. Cor-ten resists the corrosive effects of rain, snow, ice, fog, and other meteorological conditions by forming a coating of dark brown oxidation over the metal, which inhibits deeper penetration and doesn't need painting and costly rust-prevention maintenance over the years. The initial weathering of the material resulted in a discoloration of the surrounding city sidewalks, as well as other nearby buildings. A cleanup effort was orchestrated by the corporation once weathering was complete to undo this damage, but the sidewalks still have a decidedly rusty tinge. The Cor-Ten steel for the building was made at the former U.S. Steel Homestead Works.
Rockwell International, which had its headquarters in the building, displayed a large model of the Rockwell-designed NASA Space Shuttle in the building's lobby until the company moved its headquarters to Southern California in 1988.
In May, 1986 two men parachuted off the roof of the tower before being arrested by Pittsburgh Police near the Civic Arena.
The tower contains over 44,000 U.S. tons (40,000 metric tons) of structural steel, and almost an acre of office space per floor. Currently, the largest tenant of the building is UPMC who occupies 500,000 square feet (46,000 m2) of office space within the tower.
Although accepted for bridges, etc., exposing structural Cor-Ten in a building was not possible using standard construction methods because steel needed to be protected by concrete or an applied insulation to meet the fire-protection requirements of building codes. Fire protection was achieved for the 18 columns of this tower by making them hollow and filled with a water/antifreeze/rust inhibitor mixture, a technique patented in the 19th century. In another building cited in 1970, the horizontal beams were also hollow and interconnected with the columns, the entire system tested to be leakproof (Wikipedia)
