The twin towers structural system is a tube in tube design, invented by Fazlur Rahman Khan. 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. Another Islamic influence on the design is that the cross section of the towers is based on a Rub el Hizb.
The towers were designed by Argentine architect César Pelli. A distinctive postmodern style was chosen to create a 21st-century icon for Kuala Lumpur.
The construction of the superstructure commenced on 1 April 1994. The building was officially opened by the Prime Minister of Malaysia’s Tun Dr. Mahathir bin Mohamad on 31 August 1999. The twin towers were built on the site of Kuala Lumpur’s race track.
