Petronas Twin Towers: A Masterpiece Of Engineering with History and Architecture I Digital Destin

The Petronas Towers are 88-story skyscrapers in Kuala Lumpur, Malaysia, standing 451.9 meters tall (1,483 feet). The Petronas Twin Towers are a marvel of modern architecture and engineering. Completed in 1998, these twin towers were the tallest buildings in the world until 2004. In this video, we take a look at the construction of these iconic structures.
Architecture, history
Fazlur Rahman Khan invented the Petronas Towers' tube-in-tube design. Tube-structured ultra-tall buildings are common.
The 88-floor towers are mostly reinforced concrete with a steel and glass facade designed to resemble Islamic art, reflecting Malaysia's Muslim religion.
The towers' cross section is based on a Rub el Hizb, with circular sectors added for office space. Circular sectors resemble Qutub Minar's base.
Rub el Hizb symbol inspired Petronas Towers Tower 1 level 43 floor plan. The Petronas Towers' cross section is a Rub el Hizb with circular sectors like the Qutub Minar.
César Pelli designed the towers. Kuala Lumpur, Malaysia's 21st-century icon is postmodern.
Petronas Towers planning began on 1 January 1992 and included wind and structural load simulations. Seven years of construction followed at the former site of the original Selangor Turf Club, beginning on 1 March 1993 with excavation. 500 truckloads of earth were moved every night to dig down 30 meters (98 ft).
The superstructure was started in April 1994. First batch of Petronas employees moved in on 1 January 1997, 3 years after construction began.
Tun Dr. Mahathir bin Mohamad opened the building on August 31, 1999. On Kuala Lumpur's racetrack, the twin towers were built. When completed, it was Malaysia's tallest building.
Boreholes showed the original construction site was on a cliff. Half the site was decayed limestone and soft rock.
The entire site was moved 61 meters (200 feet) to sit on soft rock. The buildings have the world's deepest foundations due to the bedrock. 104 60- to 114-meter-deep concrete piles were dug.
Each tower's concrete raft foundation was poured over 54 hours.
The 4.6-meter-thick, 35,800-ton raft held the world record for the largest concrete pour until 2007. Bachy Soletanche finished the foundations in 12 months using tons of concrete.
Due to the Malaysian government's deadline, two construction consortia were hired, one for each tower.
Tower 1, the west tower, was built by a Japanese consortium led by the Hazama Corporation (JA Jones Construction Co., MMC Engineering Services Sdn Bhd, Ho Hup Construction Co.
Tower 2 was built by a South Korean consortium led by Samsung C&T Corporation (Kukdong Engineering & Construction and Syarikat Jasatera Sdn Bhd).
An early batch of concrete failed a strength test, halting construction. Only one of the completed floors used a bad batch and was demolished. Each new batch of concrete was tested after the failure.
The construction stoppage cost US$700,000 per day and led to the installation of three concrete plants so that if one produced a bad batch, the other two could continue to supply concrete. Kukdong Engineering & Construction built the skybridge. Tower 2 (Samsung C&T) was the tallest at the time.
Due to high steel import costs, the towers were built with super high-strength reinforced concrete. Asian contractors are familiar with high-strength concrete, which is twice as effective as steel in sway reduction but makes the building twice as heavy on its foundation.
The towers use a sophisticated structural system that accommodates their slender profile and provides 560,000 square meters of column-free office space. Below the twin towers are Suria KLCC and Petronas Philharmonic Hall.
