The Petronas Twin Towers are acclaimed to be the tallest twin buildings
of the world. Located at KLCC complex in Kuala Lumpur, Twin Towers
undoubtedly are the pride of Malaysia. These buildings were constructed
during 1992-1998 though were officially opened in 1999. They were
assumed to be world's tallest structure from 1998 till 2004, however,
the construction of Taipei 101 surpassed them with its additional 13
floors in 2004. Petronas, the national oil company of Malaysia, embarked
to build the tallest building in the world.
Cesar Pelli, an Argentine-American architect, designed these towers
that were tallest in the world on the date of completion. The 88-floor
towers are raised mainly of reinforced concrete, with their façade
crafted in steel and glass. Petronas Towers are a glistening example of
modern hi-tech architecture and reverence of established religion, as
the marvelous facade bears motifs found in Islamic art. Since the
bedrock was deep, the buildings came to be known as the towers erected
on the world's deepest foundations.
The 120-meter foundations called for huge amounts of concrete and were
laid by Bachy Soletanche. Whilst Tower 1 was built by the South Korean
multinational-Samsung Engineering & Construction, Hazama Corporation
of Japan constructed the Tower 2. They were built on a cheaper radical
design of high strength reinforced concrete as a consequence of lack of
steel and massive cost of importing steel. However, this high-strength
concrete made the building twofold heavy if compared with a steel
The Twin Towers make use of sophisticated structural system, supported
by 23-by-23 meter concrete cores and an outer loop of widely-spaced
super columns, which maintains their slender profile. This entire
forecast now crafts 1300-2000 square meters of column-free space for
office at each floor. Regarding the tenants, Tower One is utterly
occupied by the Petronas and its subsidiaries and associate companies.
In Tower Two, the office spaces are mainly obtainable for lease to other
towers encompass a skybridge, which was built by Kukdong Engineering &
Construction. This skybridge lies between the two towers on 41st and
42nd floors, making itself the world's highest 2-story bridge. The
bridge is 170 m above the ground, 58 m long and weighs 750 tons. The
same floor is also called Podium because the visitors, wishing to go to
the higher levels, have to change elevators here. It is open to all
visitors, though entry is limited to 1700 people per day.
The skybridge also works as a safety device, seeing as in case of fire
or other emergency in one tower, tenants can evacuate by crossing the
bridge to the other tower. Up till 2004, Petronas Towers were the
world's tallest buildings on measured from the main entrance to the
structural top, the initial height reference used by the US-based
Council on Tall Buildings and Urban Habitat from 1969. Since the height
computation reference is vague, at times, controversies have cropped up
regarding the procedure.
