Public Plaza
At ground floor level the public plaza which
passes beneath the tower is interrupted by
just eight steel masts that carry the entire
weight of the superstructure down to bedrock,
and transfer wind loading to the foundation.

Interior Atrium Space
the uninterrupted public passage
under the building precludes a sense
of grand processional entrance. The two
angled escalators (so positioned at thedirective
of the Chinese feng-shui, or
environmental
diviner, as are a number of other
elements in the building) that lead up
through the curved belly into the
banking
hall do provide a surrealistic effect,
but do not make up for the paucity of
the generalized plaza experience.

Vertical Movement/
Circulation
Vertical
Organization/Solid&Void
Each zone accommodates a single bank function
or several related ones, and the concept
is that the zones are social villagessubsets of the bank as a whole,
with which the employees identify.
Diagrams
In circulation, functional zones
correspond to these five structural ones
The truss levels are double height and have
specialized common functions (reception,dining..)
and the high-speed elevators, locate at the
west side of the building, are programmed
to stop at them
From these floors, vertical circulation is via
escalators, to provide a more sociable way of
moving through the zones than by elevator.

Primary Structure
Structure
At five intermediate levels,
suspension trusses suspend
the weight of the floors in the
zone below.
The structure of the building is its most
striking aspect, visually and functinally.
Both for reasons of flexible office planning and toallow clear views of the harbor from all points,
the floors are virtually column-free.
Eight mast towers, each composed of four
tubular steel columns connected by
hauched beams to act as Vierendeel
trusses, rise on either side of the building,
the front and back pairs located outside the building envelope.

The dramatization of movement continues in the double-story levels,
where switch-back escalators, along with trusses and hangers, sweep
through the space, and where glass elevator shafts and escalator
undercarriages reveal the motion of machinery.
At the central elevator core,
Foster has pulled the flooraway from the elevator shafts,
allowing a view of them rising
through the building.

There are 139 modules stacked
in towers on the east and west
sides of the building. They are
linked together by risers which
were also prefabricated in two
and three-storey high steel
frames.
ModulesSpeed, quality and compactness:
these were the three main reasons
for the decision to package the air-
handling plant and lavatories into
container-size modules.

The mirrors move in one
plane only, adjusting
to the height of the sun
above the horizon
but not to its east/west
position. This means that
the light falling inside the
building moves across the
atrium space during the day,
just as it would ifshiningdirectly through a skylight.
The mechanism is basically
the same as that for
motorized external louvers,
except that the motors are
controlled by a computer
programmed to know
precisely how high the sun
will be on every day of the
year.
