A case study on prefabrication

1. MINISKYCITY,CHINA
World’s tallest prefab tower

2. • Located in Central China
• 200 metre tall
• world’s tallest prefabricated building
• Floors above ground: 57
• Floors below ground: 2
• Total GFA: 1,79,600 sq.m.
# apartments: 800
# parking spaces:1090
• Elevator speed: 4m/s
• assembled in 19 working days
• Material: steel and glass
Introduction

3. • The first 10 floors of the 200-meter-tall tower are offices
• 47 floors have 800 apartments in 20 different sizes that range
from 90 to 600 sm.
• office space for 4,000 workers
• each three storeys (30fthigh) are connected with a ramp
• Kindergarten
• education centre
• organic farm
• restaurant
• 19 atriums, include tennis courts, theatres and cinemas, and a
botanic garden.

4. • Planning is same as that of conventional
Construction
• Light weight furniture is used
• Modular kitchens are provided

5. Triple heighted entrance hall

7. • Running through the building’s interior is a 3.6-km
“sky street,” which accommodates bicyclists.
• The idea is that these areas form 'sky streets' to
form communal spaces for anything from
basketball games to vertical farms.
• This encourages residents to move away from
elevators and towards a more traditional, collegial
form of living.
Ramp ( 2.5 m wide)

8. • Prefabricated construction
• construction costs reduced by 20%
to 40%
• It would have taken two years to
construct a similar building
using conventional methods
• building’s foundation was prepared
and completed in five months
• 30 days to prepare the job site
• Assembling three stories per day.
• first 20 floors erected in seven
working days
• Other 37 floors were erected in 12
days after a gap of 1 year
• 80% more energy efficient than
comparable structures in China
• 20-cm-thick thermal insulation on
walls
• three- and four-pane windows
have been used
Construction details

11. • building can withstand a 9-magnitude earthquake, according to
independent testing by the China Academy of Building Research
• five times more energy efficient than its conventional
counterparts
• a combined cooling, heating and power system that makes the
building extremely energy efficient
• 24/7 100% clean, fresh air to create a healthy environment amidst
China’s smog.
• air conditioning operating costs are next to nothing because of the
waste heat.
• 12,000 tonnes of CO2 cutting compared to other same-sized
buildings
Features

12. • the air conditioning machine room is located in the basement of
the building
• More use of ceiling lights and down lighters
• a combined cooling, heating and power system
• 100 per cent filtered fresh air
• 5 Lifts
• Ramp (no staircase)( easier for handicapped and old persons to
move from one place to another)
