Petronas Towers: Difference between revisions

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.
