The '''Petronas Towers''' ({{langx|ms|Menara Berkembar Petronas}}), also known as the '''Petronas Twin Towers''' and colloquially the '''KLCC Twin Towers''', are an [[Twin towers (architecture)|interlinked pair]] of 88-storey [[List of supertall skyscrapers|supertall skyscrapers]] in [[Kuala Lumpur]], Malaysia, standing at {{convert|451.9|m|abbr=off}}. From 1996 to 2004, they were the [[List of tallest buildings|tallest buildings in the world]] until they were surpassed by the [[Taipei 101]] building. The Petronas Towers remain the world's [[List of tallest twin buildings and structures|tallest twin skyscrapers]], surpassing the original [[World Trade Center (1973–2001)|World Trade Center]] towers in New York City, and were the [[List of tallest buildings in Malaysia|tallest buildings in Malaysia]] until 2021, when they were surpassed by [[Merdeka 118]]. The Petronas Towers are a major landmark of Kuala Lumpur, along with the nearby [[Kuala Lumpur Tower]] and [[Merdeka 118]], and are visible in many places across the city.

==History and architecture==
The Petronas Towers' [[structural system]] is a [[Tube (structure)|tube in tube design]], invented by Bangladeshi-American architect [[Fazlur Rahman Khan]].<ref>{{Cite magazine |date=2010 |title=Tall Buildings in Numbers |url=http://www.ctbuh.org/LinkClick.aspx?fileticket=rlKQFdZyhwg%3D&tabid=1108&language=en-GB |magazine=CTBUH Journal |volume=2010 |issue=2 |pages=40–41 |access-date=13 January 2015 |archive-date=24 July 2018 |archive-url=https://web.archive.org/web/20180724154150/http://www.ctbuh.org/LinkClick.aspx?fileticket=rlKQFdZyhwg%3D&tabid=1108&language=en-GB |url-status=dead }}</ref><ref>{{Cite book |url=https://books.google.com/books?id=K792dXxSI4UC&q=tube+in+tube+petronas+tower&pg=PA24 |title=Structures in the New Millennium: Proceedings of the Fourth International Kerensky Conference on Structures in the New Millennium, Hong Kong, 3–5 September 1997 |date=1997 |publisher=A.

The 88-floor towers are constructed largely of reinforced concrete, with a steel and glass facade designed to resemble motifs found in [[Islamic art]], a reflection of Malaysia's [[Muslim]] religion.<ref>{{Cite book |title=Local Cultures and the "New Asia": The State, Culture, and Capitalism in Southeast Asia |date=2002 |publisher=Institute of Southeast Asian Studies |editor-last=Wee |editor-first=C.

The towers were designed by [[Argentine Americans|Argentine-American]] architect [[César Pelli]]. A distinctive [[Postmodern architecture|postmodern]] style was chosen to create a 21st-century icon for Kuala Lumpur, Malaysia. Planning on the Petronas Towers started on 1 January 1992 and included rigorous tests and simulations of wind and structural loads on the design. Seven years of construction followed at the former site of the original [[Selangor Turf Club]], beginning on 1 March 1993 with excavation, which involved moving 500 truckloads of earth every night to dig down {{Convert|30|m}} below the surface.
The construction of the superstructure commenced on 1 April 1994. Interiors with furniture were completed on 1 January 1996, the spires of Tower 1 and Tower 2 were completed on 1 March 1996, 3 years after its construction was started, and the first batch of [[Petronas]] personnel moved into the building on 1 January 1997. The building was officially opened by the [[Prime Minister of Malaysia]], [[Mahathir Mohamad|Tun Dr. Mahathir bin Mohamad]], on 31 August 1999.<ref>{{Cite book |last=Sebestyén |first=Gyula |title=Construction: Craft to Industry |date=1998 |publisher=Taylor & Francis |isbn=978-0-419-20920-1 |location=London |page=205}}</ref> The twin towers were built on the site of Kuala Lumpur's race track. It was the tallest structure in [[Malaysia]] at the time of its completion.<ref>{{Cite book |last1=Žaknić |first1=Ivan |title=100 of the World's Tallest Buildings |author2=Smith, Matthew |author3=Rice, Doleres B. |date=1998 |publisher=Images Publishing |isbn=978-1-875498-32-1 |location=Mulgrave, Victoria |page=208}}</ref> Test boreholes found that the original construction site effectively sat on the edge of a cliff. One half of the site was decayed limestone while the other half was soft rock. The entire site was moved {{convert|61|m|ft}} to allow the buildings to sit entirely on the soft rock.<ref name="Anstey">National Geographic Channel International / Caroline Anstey (2005), ''Megastructures: Petronas Twin Towers''</ref> Because of the depth of the [[bedrock]], the buildings were built on the world's deepest foundations.<ref>{{Cite journal |last1=Baker |first1=Clyde N.

The concrete raft foundation, comprising {{Convert|13200|m3}} of concrete was continuously poured through a period of 54 hours for each tower. The raft is {{convert|4.6|m|ft}} thick, weighs {{Convert|32500|tonne}} and held the world record for the largest concrete pour until 2007.<ref name="Anstey"/> The foundations were completed within 12 months by Bachy Soletanche and required massive amounts of concrete.<ref>{{Cite web |date=18 March 2010 |title=Detailed Structural Analysis |url=http://www.thepetronastowers.com/2010/03/petronas-towers-%E2%80%93-detailed-structural-analysis/ |archive-url=https://web.archive.org/web/20101101221729/http://www.thepetronastowers.com/2010/03/petronas-towers-%E2%80%93-detailed-structural-analysis/ |archive-date=1 November 2010 |access-date=11 January 2011 |website=The Petronas Towers }}</ref>
 
As a result of the Malaysian government specifying that the buildings be completed in six years, two construction consortia were hired to meet the deadline, one for each tower. Tower 1, the west tower (left in the top-right photograph) was built by a Japanese consortium led by the [[Hazama Corporation]] ([[J.A. Jones Construction|JA Jones Construction Co.]], MMC Engineering Services Sdn Bhd, Ho Hup Construction Co. Bhd and [[Mitsubishi Corporation|Mitsubishi Corp]]) while Tower 2, the east tower (right in the top-right photograph) was built by a South Korean consortium led by the [[Samsung C&T Corporation]] (Kukdong Engineering & Construction and Syarikat Jasatera Sdn Bhd).

Early into construction a batch of concrete failed a routine strength test causing construction to come to a complete halt. All the completed floors were tested but it was found that only one had used a bad batch and it was demolished. As a result of the concrete failure, each new batch was tested before being poured. The halt in construction had cost US$700,000 per day and led to three separate [[concrete plant]]s being set up on the site to ensure that if one produced a bad batch, the other two could continue to supply concrete. The sky bridge contract was completed by Kukdong Engineering & Construction. Tower 2 (Samsung C&T) became the first to reach the world's tallest building at the time.

Due to the huge cost of importing steel, the towers were constructed on a cheaper radical design of super high-strength reinforced concrete.<ref>{{Cite book |last=Wells |first=Matthew |title=Skyscrapers: Structure and Design |date=2005 |publisher=Laurence King Publishing |location=London |page=170}}</ref> High-strength concrete is a material familiar to Asian contractors and twice as effective as steel in sway reduction; however, it makes the building twice as heavy on its foundation as a comparable steel building. Supported by 23-by-23 metre concrete cores<ref>"Information Malaysia." (2005). Berita Publ. Sdn. Bhd.</ref> and an outer ring of widely spaced super columns, the towers use a sophisticated structural system that accommodates its slender profile and provides 560,000 square metres of column-free office space.<ref>{{Cite book |last=Taranath |first=Bungale S. |title=Wind and Earthquake Resistant Buildings: Structural Analysis and Design |date=2004 |publisher=CRC Press |page=748}}</ref> Below the twin towers is [[Suria KLCC]], a shopping mall, and [[Petronas Philharmonic Hall]], the home of the [[Malaysian Philharmonic Orchestra]].

* Thousands of people were evacuated on 12 September 2001 after a bomb threat the day after the [[September 11 attacks]] destroyed the [[World Trade Center (1973–2001)|World Trade Center]] towers in New York City. Bomb disposal squads found no explosives in the towers, but they nevertheless evacuated the premises. Workers and shoppers were allowed to return three hours later, around noon. No one was hurt during the evacuation.<ref>{{Cite news |last=Yoong |first=Sean |date=12 September 2001 |title=World's Tallest Towers, IBM Building in Malaysia Evacuated After Threats |work=Lubbock Online: The Avalanche Journal |agency=Associated Press |url=http://www.avalanchejournal.com/stories/091201/upd_worldevacs.shtml |access-date=11 January 2011 |archive-url=https://archive.today/20120719154930/http://www.avalanchejournal.com/stories/091201/upd_worldevacs.shtml |archive-date=19 July 2012}}</ref>
* On the evening of 4 November 2005, a fire broke out in the [[Tanjong Golden Village|cinema complex]] of the Suria KLCC shopping centre below the Petronas Towers, triggering panic among patrons. There were no reports of injuries. The buildings were largely empty, except the shopping mall, Suria KLCC, because of the late hour; the only people involved were moviegoers and some diners in restaurants.<ref>{{Cite news |date=4 November 2005 |title=Fire Forces Evacuation at Malaysia Towers |work=CBS News |url=https://www.cbsnews.com/stories/2005/11/04/ap/world/mainD8DLSFK00.shtml |access-date=11 January 2011 |archive-url=https://web.archive.org/web/20081207081700/http://www.cbsnews.com/stories/2005/11/04/ap/world/mainD8DLSFK00.shtml |archive-date=7 December 2008}}</ref>

==Features==

===Suria KLCC===
{{Main|Suria KLCC}}

[[Suria KLCC]] is a {{convert|140000|m2|abbr=on}} upscale retail center at the foot of the Petronas Towers. It features mostly foreign luxury goods and high-street labels. Its attractions include an art gallery, an underwater aquarium and also a Science center. Boasting approximately 300 stores, Suria KLCC is touted as one of the largest shopping malls in Malaysia.<ref>{{Cite book |last1=de Ledesma |first1=Charles |title=Malaysia, Singapore and Brunei |last2=Lewis |first2=Mark |last3=Savage |first3=Pauline |date=2003 |publisher=Rough Guides |isbn=1-84353-094-5 |edition=4th |location=New York |page=132 }}</ref> The [[Petronas Filharmonik Hall|Petronas Philharmonic Hall]], also built at the base of the towers, is frequently associated with Suria KLCC's floorspace. During holidays or celebration days, Suria KLCC is the top spot to see the decorations especially at the main entrances and also in Centre Court. It also promotes the uniqueness and beauty of Malaysia's cultural diversity towards the visitors.

===KLCC Park===
{{Main|KLCC Park}}
[[File:KLCC Park 2010.jpg|thumb|[[KLCC Park]]]]
Spanning {{convert|17|acre}} below the building is the [[KLCC Park]] with jogging and walking paths, a fountain with incorporated light show, wading pools, and a children's playground.

===Skybridge===
The towers feature a double decker [[Skyway|skybridge]] connecting the two towers on the 41st and 42nd floors, holding the record for the highest 2-story bridge in the world.<ref>{{Cite book |last=Frankham |first=Steve |url=https://archive.org/details/isbn_9781906098117/page/68 |title=Malaysia and Singapore |date=2008 |publisher=Footprint Travel Guides |isbn=978-1-906098-11-7 |location=Bath |page=[https://archive.org/details/isbn_9781906098117/page/68 68] |url-access=registration}}</ref>  The skybridge also functions as a crucial design feature facilitating movement between the two towers during high winds.<ref>{{Cite book |last=Moskal |first=Greg |title=Modern Buildings: Identifying Bilateral and Rotational Symmetry and Transformations |date=2004 |publisher=i Rosen Classroom |page=26 }}</ref> The bridge is {{convert|170|m|ft|0|abbr=on}} above the ground and {{convert|58.4|m|ft|0|abbr=on}} long, weighing 750 tons.<ref>{{Cite book |title=Structural Health Monitoring 2005: Advancements and Challenges for Implementation |date=2005 |publisher=DEStech Publications |isbn=1-932078-51-7 |editor-last=Chang |editor-first=Fu-Kuo |location=Lancaster, Pennsylvania |page=270}}</ref> The same floor is also known as the podium, since visitors going to higher levels have to change elevators here. Dynamic analyses were performed and iterated to support the final design by studying the structural behavior of the twin towers to time-varying loads such as earthquakes and wind.<ref>{{Cite web |last=Chalhoub |first=Michel Soto |url=http://parsons.com |title=Dynamic Analysis and Design of KLCC Twin Towers for Seismic and Wind Loads |date=1990 |website=Parsons Engineering Library}}</ref>{{failed verification|date=August 2023}} The skybridge is open to all visitors, but tickets are limited to about 1,000 people per day, with around half available to be purchased online, and the other half obtained on a first-come, first-served basis. Petronas began selling tickets in 2010, eliminating free visits. Visitors can choose to opt for package one which is just a visit to the skybridge or go for package two to go to the skybridge and all the way to level 86.<ref>{{Cite web |date=25 October 2010 |title=The Petronas Towers Skybridge |url=http://www.thepetronastowers.com/petronas-skybridge/ |archive-url=https://web.archive.org/web/20091107213544/http://www.thepetronastowers.com/petronas-skybridge/ |archive-date=7 November 2009 |access-date=2 December 2010 |website=ThePetronasTowers.com }}</ref> Visitors are only allowed on the 41st floor as the 42nd floor can only be used by the tenants of the building.<ref>{{Cite book |last1=Rowthorn |first1=Chris |title=Borneo |last2=Cohen |first2=Muhammad |last3=Williams |first3=China |date=2008 |publisher=Lonely Planet |location=Footscray, Victoria |page=71}}</ref>

The skybridge also acts as a safety device, so that in the event of a fire or other emergency in one tower, tenants can evacuate by crossing the skybridge to the other tower.<ref>{{Cite journal |last1=Wood |first1=A. |last2=Chow |first2=W.

There is a two hinged arch that supports the skybridge with arch legs, each {{Convert|51|m}} long, that are bolted to level 29 of each of the towers.<ref name="Petronas">{{Cite web |title=The Petronas Twin Towers Official Website |url=http://www.petronastwintowers.com |access-date=29 March 2012 |website=Petronas Twin Towers}}</ref> After being constructed on the ground, the skybridge was lifted into place on the towers over a period of three days<ref name="Academic Search Premiere">{{Cite magazine |last=Wheeler |first=Mark |date=May 1996 |title=The World's Tallest Building |url=https://books.google.com/books?id=MWUEAAAAMBAJ&pg=PA78 |magazine=[[Popular Mechanics]] |pages=78–81 |via=Google Books}}</ref> in July 1995.<ref name="Petronas" /> Residing on the 41st and 42nd floors, the skybridge connects a conference room, an executive dining room and a prayer room.<ref name="Academic Search Premiere" />

===Lift system===
The main bank of [[Elevator|lifts]] is located in the centre of each tower. All main lifts are [[double-deck elevator|double-decker]] with the lower deck of the lift taking passengers to even-numbered floors and upper deck to odd-numbered floors. To reach an odd-numbered floor from ground level, passengers must take an [[escalator]] to the upper deck of the lift.<ref name="ls">{{Cite web |date=25 October 2010 |title=Petronas Towers Lift System |url=http://www.thepetronastowers.com/petronas-towers-lift-system/ |archive-url=https://web.archive.org/web/20091107211801/http://www.thepetronastowers.com/petronas-towers-lift-system/ |archive-date=7 November 2009 |access-date=2 December 2010 |website=The Petronas Towers }}</ref>

There are 29 double-deck passenger elevators, but there are different sets that service certain floors of the towers, specifically two sets of six of these double-deck passenger elevators to floors 1–23 and 1–37 respectively. Another set of 5 passenger lifts transport passengers to the 41st and 42nd floors where they can switch lifts to reach the upper zones of the buildings, each double-deck passenger lift with the capacity of 52 passengers or, 26 passengers per deck. There are also 6 heavy-duty elevators for utility.
