Jakarta Signature Tower is a projected skyscraper in Jakarta, Indonesia. With a height of 638 m (2,093 ft) upon completion, it would become the sixth tallest skyscraper in the world. It was originally proposed in 2010 and was slated to begin construction in 2015. Planning permission for the tower was granted in late 2015, and construction is now scheduled to begin in the third quarter of 2016 assuming a loan of approximately $1.5 billion can be successfully secured.
The skyscraper is a part of a 50 acre redevelopment project SCBD, near the Semanggi Interchange and is just south of the Gelora Bung Karno Stadium. It is within Golden Triangle of Jakarta in Jakarta where the majority of major development areas are located. When completed, the structure will include 6 basement floor used for parking space while the podium will feature retail, convention and entertainment venues with the rest of the skyscraper used as office and residential space.
Due to the presence of unstable alluvial deposits within the Jakarta Basin and the seismic prone area from where the skyscraper will be built, the design must comply with seismic criteria using a probabilistic seismic hazard analysis (PSHA) defined by the Pacific Earthquake Engineering Research Center (PEER), Tall Buildings Provisions and the American Society of Civil Engineers (ASCE). In addition, wind tunnel tests must be conducted under city regulations due to the height of the building exceeding 50 stories and 200 m (656 ft). Aerodynamic testing was performed by applying a scaled wind velocity on a 1:500 scale model of the skyscraper equivalent to applying an average hourly wind velocity of 40 m/s on the actual design.
On 13 July 2017, acting governor of Jakarta Djarot Syaiful Hidayat attended a regional meeting with the developers, discussing about the UDGL (Urban Design Guide Line) and finally reached an agreement to integrate the tower with the ongoing developments of the Jakarta MRT. Djarot later sent a letter to Indonesian President Joko Widodo, requesting him to make the tower to become a national icon.
