Over the past 40 years, Center City has become home to multiple structures over the height of 500 feet. Philadelphia City Hall was the tallest structure in Philadelphia from 1894 to 1986 at 548, then in 1987 the steel structure of One-Liberty-Place eventually passed the statue to soon top out its spire at 945 feet. The same developers of Liberty Place also developed the next tallest skyscraper in the city, the 974-foot Comcast Center from 2007 to 2017. In 2017, across the street to the west, the Comcast Technology Center became the tallest skyscraper in the city since 2017 and its first supertall skyscraper at 1,121 feet. For this development, Comcast had partnered with Liberty Property Trust, which was originally known as Rouse and Associates. The tower was designed by Foster and Partners, which has designed iconic structures such as the Gherkin in London and the Hearst Tower in Midtown Manhattan. Today Philly YIMBY looks back at the period when the iconic tower’s spire topped out.
The photographs are taken just under two months after the topping of the tower, with the glass on the lantern already underway at the time. When first witnessing the completed steel structure, a sense of relief and amazement flows as the tower reaches an incredible height and the structure was done rising. The tower crane attached to the south side of the tower had its cab at a height around 1,030 feet, as the tip of the boom stood a a height of 1,150 feet when maneuvered to its highest angle.
On the west side of the skyscraper, the temporary construction elevator was coming down to soon install the glass on the “spine” of the building. The cladding on the skyscraper not including the cooling towers and spire have been completed since October 2017, giving a glimpse at the final look of the skyscraper though lots of protective blue tape was on the metal cladding.
