SKY CITY STRIVES FOR RAPID CONSTRUCTION TURNOVER
In the past, Super Tall Buildings demanded 5-10 years to construct, whereas Sky
City needs only 7 months (after foundation), its size is twice as large as the largest
building in the world
90% factory-made (on-site construction work
is only 10% of conventional construction work)
Flooring, ceiling, water & electricity supplies,
HVAC & etc are fitted in a 60m2module. Walls,
windows and doors are stacked on a module.
Bolt connection for all of on-site installation

SKY CITY STRIVES FOR A LONGER LIFE SPAN
The durability of steel structure building has
been proven by Eiffel Tower, whereas Sky
City with its steel structure free from the rain
enjoys better anti-corrosion treatment than
Eiffel Tower did
Steel materials are different from concrete, with noaging issues
Cold galvanizing anti-corrosion technology is used
Tight thermal insulation prevents condensation
corrosion
Anti-corrosion treatment/each 60 years, as durable
as a new one
After decommissioning, all steel materials can be reused
Stocking resources for future generations, leaving

SKY CITY GIVES AN IMPETUS TO THE
NEXT STEP IN CHINESE URBANIZATION
Not all wrong deeds can be undone, urbanization in a
country is once for all. Sky City with its No.1 Altitude has
championed its energy & land conservation concept
in the future development of Chinese urbanization
Buildings ought to be developed towards the
sky and towards mixed-use community
Urbanization can not be materialized at the
cost of land and environmental pollution
China can tread on a road of Energy-saving,
Land-saving Urbanism

SKY CITY STRIVES FOR THE GLOBAL NEW
SIGNPOST OF SUSTAINABLEDEVELOPMENT
The world population is increasing at 1.8% year by year and CO2
emissions at 5% year by year. In the near future, environment
pollution & climate change may breach the critical point while
humans become helpless. When Sky City with its strong signal
comes into being, is like a huge signpost on the vast seas
The global urban territory is not supposed toexpand only, but can be contracted as well
The global vehicles are not meant to
increase only, but can be lessened as well
The global CO2emissions can be controllable
Humanity can find a real approach to sustainable
development for higher life quality and lower
impact on the environment
