Cheng Xiong Shanghai World Financial Center Project Challenges & Solutions da (pinyin) = big Asian Financial Crisis in 1997-1998 caused construction to be postponed just after the foundation was laid.

The SWFC tower was originally planned for construction in 1997
Financial Problems
Resulted in an increase in gross area of approximately 15%

An increase in overturning moment from wind forces of approximately 25%.

The increase in size resulted in a new building design and new structural system due to the increase in weight.
Increased Size Composite (Mega) columns
Impressive size
2 in diameter reinforcing steel (largest size available) bundled into sets of four bars.
At base of the building, the columns are 17’-11” x 17’-11” Mega-Structure On August 14th 2007, a fire broke out in the building.

The fire claimed no lives and was quickly put out, but yet another setback to an already troubled project. Fire Damages Project Participants Project Architect: Kohn Pederson Fox Associates

“Create and experience like a small village gathered at the base of a cathedral.” - Pederson
Trapezoid aperture at the peak
Originally was a circle but was changed
Design subtext in Chinese methodology Architecture and Design Awards Youngest firm to receive the Architectural Firm Award from AIA

Won over 300 awards February 13th, 2003 construction resumed with 2,000 workers 24/7

New Goals:
Tallest in China’s mainland
492 meters (1614 feet)
101 floors (weights 10x the Eiffel Tower)

Mega-structure needs Mega-Crane (7:10-9:00)

250 tons M900D Reconstruction Team 1: Mega-columns
Team 2: Elevator Core
Team 3: Floor Builders
Team 4: Glass Curtain Walls Team Build Steps:
1) bolt columns
2) wields the two pieces together
3) wrapped dense rebar case around it
4) enclosed in wooden woodwork
5) pour in half a dozen truck load of concrete into it. Mega-Columns Building Spine

Steel Truss

20 motors

Holds 88 elevators Elevator Core Over 150km of REBAR per floor used for steel floor plate
Over a total of 15,000km rebar
Distant from earth to international space station and back 19 times

650 tons of steel per floor (19 elephants)
Each floor requires a massive amount of concrete
Constructed 1 floor every 2-3 days Floor Builders Installed 10,000 windows (24:58-27:35)
- Average of 15 windows per day
- Complete 1 floor about 3-4.5 days

Curtains walls made of double-paned glass
- Provide effective insulation
- Minimize internal heat loss
- Improve AC efficiency and reduce AC costs Window Installation Made SWFC glass by hands
15 min per panel

Consists of the large glass, aluminum frame, & silicon weather seal

One panel = 60kg = 132.2 lb Permasteelisa KPF’s concerns for a post 9/11
- Fire-proof Core
- External elevator emergency exits
- Special design refuge floor

Built to survive nature and man disasters
NG (40:19-44:30) Post 9/11 Incorporations Final steel girder was installed on September 14th, 2007

Top tier consists of 2 observation decks

Tallest in mainland China

16m shorter than Taipei 101’s spire atop but 44m taller by roof height Finalizations Constructions Shanghai Tower
Status: Under Construction
Designer: Gensler
Tallest (632m or 2073 ft, 121 stories) in China, World 2nd Tallest
Est. Completion in 2014
9 cylindrical buildings stacked
World’s first adjacent of 3 supertowers Future Alluvial deposits/very soft soil
The site’s soft soil required 2,200 piles
Driven up to 250 feet into the ground Shanghai’s Soft Soil Taipei 101building being built, tallest of its time.
Mori group wanted to be taller than Taipei 101
Increased height from 95 stories to 101 stories to surpass the Taipei 101’s top floor. Increased Size A decrease in weight had to be found
Accomplished by attaching outrigger trusses to columns of the mega-structure. Mega-Structure Built in 12 story section.
Used less steel
Made the building lighter. Mega-Structure High winds worst enemy
Creates an over-turning moment
Placed a hole at top of the building to let wind thru. Increased Wind and Earthquake Forces With high winds or earthquakes, vibrations creates whiplash motion
Place two mass dampers at the top
Dampers will counteract the sway of the top of the building Increased Wind and Earthquake Forces Mega-Structure
