The tower is located on the southwest corner of 18th andArch Streets, one block west of theComcast Center, the headquarters ofComcast Corporation. A hotel, representing the highest hotel in the nation,[1] and restaurant are located on the top floors. The building's central floors are offices for Comcastsoftware developers andengineers, and the lowest floors have television studios and retail stores.[9][10]
Construction on the building began in mid-2014 and was completed on November 27, 2017.[1][10] The first personnel began moving into the building in late July 2018,[11] and the tower was open to the public in October of that year.[12]
The lead architect wasFoster and Partners,[13][14][15] with Kendall/Heaton Associates the collaborating architect,[3] and interior design byGensler with Foster and Partners in collaboration.[16] The L.F. Driscoll Company was the construction contractor. The tower contains approximately 1.566 million rentable square feet, including 1.334 million rentable square feet of office space, 230,112 square feet of hotel space, and 2,682 rentable square feet of retail space.[2]
A set of five tuned sloshingdampers containing 125,000 gallons of water are located in the ceiling of the 57th floor, beneath the hotel lobby. The moving water is a counteracting force on windy days to reduce swaying of the upper part of the tower. A-shaped steel braces are embedded between hotel rooms on the east and west sides, to stiffen the upper part of the building against strong winds.[17]
