The Exchange 106

The Exchange 106 (Malay: Menara Exchange 106), formerly known as the TRX Signature Tower, is a 445.5-meter-tall (1,462-foot) supertall skyscraper in Kuala Lumpur, Malaysia. It is the fourth-tallest building in Malaysia and the fifth-tallest building in Southeast Asia. It is also the second largest skyscraper in Malaysia by floor area with 453,885 m (4,886,000 sq ft). The tower has a net lettable area of 240,000 square metres (2.6 million square feet). It is also the centerpiece of the new Tun Razak Exchange (TRX) financial district.
The Exchange 106 is currently the 23rd tallest building in the world according to the Council on Tall Buildings and Urban Habitat (CTBUH) and the fourth-tallest building in Malaysia, standing behind the Petronas Twin Towers by 6.4 meters.
As of October 2019, about 46,000 m (500,000 sq ft) of Exchange 106's floor space was expected to be taken up by tenants. The floor space is column-less, ranges from 2,600 to 3,200 m (28,000 to 34,000 sq ft).
The skyscraper was first conceptualized when TRX was controlled by 1Malaysia Development Berhad (1MDB), a sovereign fund owned by the Government of Malaysia. On 13 May 2015, 1MDB Real Estate Sdn Bhd (1MDB RE), the master developer of TRX, and the Mulia Group announced that, through Mulia Property Development Sdn Bhd, they had signed a Sale and Purchase agreement for the development rights of the plot of land for the Exchange 106 (then known as the Signature Tower), with the land transacted at a value of RM665 million. Groundwork on the Exchange 106 plot commenced on 1 March 2016, with the mat concrete foundation laid in May 2016 (see "Progress" section below).
Presently, Mulia Property Development Sdn Bhd is 51% owned by the Ministry of Finance through MKD Signature Sdn Bhd and 49% by Mulia International.
The Exchange 106 was managed by the Mulia Group, with structural construction carried out by the China State Construction Engineering Corporation, through its Malaysian subsidiary China State Construction Engineering (M) Sdn. Bhd.
In May 2016, the tower's foundation concrete pour took place over a weekend and was the second-largest continuous concrete pour in the world. In December 2017, the building was structurally topped out, 19 months after commencement, achieving an average of 3 days a floor.
Exchange 106 achieved its Certificate of Completion and Compliance in September 2019.
The construction of the TRX's shopping mall (known as The Exchange TRX) which is located at the foot of the Exchange 106 was expected to be completed by the third quarter of 2021. Later on, the construction of the mall was delayed due to the strict Movement Control Order (MCO) in the country caused by the COVID-19 pandemic. The completion of the mall was pushed back to 2022 and but was subsequently opened in November 2023.
As of December 2021, the overall infrastructure of TRX was at 80 percent completion, while The Exchange TRX mall was expected to be completed in the third quarter of 2023.
The tower, along with Merdeka 118, has often been referred by many Malaysians as highly unnecessary and a "national disgrace", with their presence on the Kuala Lumpur skyline "tainted" and signifying the legacy of the scandal.
Mulia Group began promoting around December 2017, during construction, that The Exchange 106 would reach a height of 492.3 meters, surpassing the Petronas Twin Towers to become the tallest building in Malaysia. However, it was later clarified that this measurement referred to the height above sea level, while the actual height above ground was 445.5 meters.
Subsequently, they introduced a new claim that the height was 453.6 meters, measured "from the entrance of a building sits on a significant podium," asserting that this surpassed the Petronas Twin Towers' height of 451.9 meters. This claim was temporarily accepted by the CTBUH, according to Mulia Group, but was later reassessed. Currently, CTBUH officially recognizes the architectural height as the original 445.5 meters.
As a result, The Exchange 106 was never the tallest building in Malaysia.
The skyscraper is currently served by the Kajang Line KG20 and the Putrajaya Line PY23 with one station, the Tun Razak Exchange MRT underground station on site. The underground station is one of two interchanges between the Kajang and Putrajaya MRT lines.
