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's Tun Dr. Mahathir bin Mohamad on 1 August 1999. The twin towers were built on the site of Kuala Lumpur's race track. 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 to allow the buildings to sit entirely on the soft rock. Because of the depth of the bedrock, the buildings were built on the world's deepest foundations. 104 concrete piles, ranging from deep, were bored into the ground. The concrete raft foundation, comprising of concrete was continuously poured through a period of 54 hours for each tower. The raft is thick, weighs and held the world record for the largest concrete pour until 2007. The foundations were completed within 12 months by Bachy Soletanche and required massive amounts of concrete. The Petronas Towers' structural system is a tube in tube design, invented by Fazlur Rahman Khan. Applying a tube-structure for extreme tall buildings is a common phenomenon.
