Petronas Twin Towers

Assalamualaikum and Peace be upon all of you..
Welcome to my blog.

In the past segment of architectural post, we have seen some of the tallest building in the world. Let us proceed futher into some of their counterparts. Let us seen the building that has become a international branding to its country, Malaysia. The Petronas Twin Towers.


It has been entitled as the tallest building in the world from 1998 to 2004 before being surpass by Taipei 101. Nevertheless, it still the tallest twin tower in the world. The tower is design by C├ęsar Pelli. The contractor for tower 1 is Hazama Corporation from Japan while contractor for tower 2 are Samsung Engineering & Construction and Kukdong Engineering & Construction from Korea.

Currently, it serve as the 2nd tallest building in the world. After the completion of Burj Dubai, its rank will be the 3rd tallest building in the world.


The buildings were built on the world's deepest foundations. The 120-meter foundations were built by Bachy Soletanche, and required massive amounts of concrete.

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 (albeit with circular sectors added to meet office space requirements). Due to a lack of steel and the huge cost of importing steel, the towers were constructed on a cheaper radical design of super high-strength reinforced concrete.

High-strength concrete is a material familiar to Asian contractors and twice as effective as steel in sway reduction; however, it makes the building twice as heavy on its foundation than a comparable steel building. Supported by 23-by-23 meter concrete cores and an outer ring of widely-spaced super columns, the towers use a sophisticated structural system that accommodates its slender profile and provides from 1300 to 2000 square metres of column-free office space per floor.


Tower One is fully occupied by Petronas and a number of its subsidiaries and associate companies. The office spaces in Tower Two are mostly available for lease to other companies. A number of companies have offices in Tower Two, including Accenture, Al Jazeera English, Carigali Hess Bloomberg, Boeing, IBM, Khazanah Nasional Berhad, McKinsey & Co, TCS, HCL Technologies, Krawler Networks, Microsoft, The Agency (a modeling company) and Reuters.

Below the twin towers is Suria KLCC, a shopping mall, and Dewan Filharmonik Petronas, the home of the Malaysian Philharmonic Orchestra.

The building is inspired by Malaysia's Father of Modernization, Tun Dr Mahathir Mohamad. Before the time of the tower, Malaysia is the least known country compare to its neighbours like Singapore, Thailand or Indonesia. After the completion of the tower, it did gave a huge impact to Malaysia to be well-known through out the globe.
