Located in Kuala Lumpur Malaysia, the Petronas Towers are 1483ft tall (including spires) and 88 stories, they were completed in 1998 at a cost of $1.6 billion. Designed by Architect Cesar Pelli, the twin towers are the headquarters for the national petroleum company of Malaysia, and have a total built up area of 3.7 millions square feet. Because of their size, the construction contract for each of the towers was awarded to a different contractor who then competed to build their tower the fastest. On their completion the towers had an immediate impact, placing Kuala Lumpur on the map of world financial centers.
