Location

• Guangzhou International Finance Centre or Guangzhou WestTower, is a 103-storey, 438.6 m skyscraper at Zhujiang Avenue

West in the Tianhe District of Guangzhou, Guangdong, China. It

is the 15th tallest building in the world. It is a part of

the Guangzhou Twin Towers.

• The building was previously known as Guangzhou West Tower

and had a related project, the proposed Guangzhou East Tower,

which, at 475 m (1,558 ft), would have been eventaller,[8] though that project has been awarded to a different

design by Kohn Pedersen Fox, the 530 m (1,740 ft) Chow Tai

Fook Centre.

and structure which makes it possible.

•The tower has a mixture of uses including office space, a

luxury hotel and a top floor observation area.

cladding.

The Form

• Its rounded triangular plan

responds to the need for

efficient internal space layouts

and excellent environmental

performance. The tower has a

mixture of uses includingoffice space, a luxury hotel

and a top floor observation

area.

• Each of the three façades of

the curved triangular plan arealso curved in section with a

radius of 5.1 kilometers (3.17

miles) set out asymmetrically

with the widest point at a third

of the height, tapering to its

narrowest point at the top.

• Has a radius of 71 m in plan

at the widest part and 10 m on

corners

• The plan of the building has

been designed to provide

approximately 165,000 sq m

(1,776,045 sq ft) of efficient

and flexible office floor plates.

Entry to bldg

• The tower has a triple height 12 m (39 ft) high

entrance lobby which rings the base of the tower and

allows secure access to the building’s double decker

shuttles and standard lift groupings.

• The main lobby also connects via escalators to a

secondary office lobby located at the lower basement

level, which in turn allows access to below groundretail and the MTR station

plan

• Office floors occupy levels 2 through 67 and a FourSeasons hotel is on levels 67 through 103.

• The office plates have good usable depths from façade

to core ranging typically from 11 –15 meters (36 –49

feet) to achieve good daylight penetration.

• Above level 66 (the highest office floor) is the five-star

Four Seasons hotel. A health club is located at level 67above which back of house and kitchen areas have

been zoned. The hotel’s main lobby is located at level

70 and is accessed via shuttle lifts serving directly from

the ground.

Cladding

• Building has smooth glass cladding with glass panels

1.5m wide and one floor high.

• With 80,000 sqm of area to be covered , glass panels of

different sizes would be difficult.

• 90 % repetition was achieved with 4 standard panel

sizes.

• A unitary system of high performance glass is used to

maintain transparency to show the structural system.


13/16

Structural system

• The building utilizes the world’s tallest constructed

diagrid structure which is clearly expressed though the

building’s façade and gives the building considerable

character.

• The diagrid members are formed from concrete filledsteel tubes which provide both good stiffness and fire

protection to the structure.

• The tubular diagrid structure “nodes-out” every 12 stories

to form 54 m (177 ft) high giant steel diamonds. At the

base of the tower the structural members are 1800 mm(70 in) in diameter and reduce in size up the building to

900 mm (35 in) at the top of the building.


14/16

• Inside the exoskeleton of diagrid system, the central core

which serves the office is made in RCC with a climbformsystem.

• The structural core takes much of the gravity load of the

building’s floors and is linked back to the diagrid

perimeter structure via floor beams to create a stiff “tube-

within-a-tube” structural system.

• The inherent stiffness in the structure minimizes steel

tonnage while providing inherent stiffness and resistance

to acceleration and sway, thereby maintaining high

comfort levels for the building’s occupants.

• This stiffness and resistance to acceleration means that

no damping of the structure is required
