This is a latest civil engineering technology used in construction of buildings, houses, roads and others. I think this ppt might be helpful to all. Thanks

3. CRAFTING

4. Contour crafting is a building printing technology under development by Behrokh
Khoshnevis of the University of Southern California’s information Sciences
Institute.
It uses a computer-controlled crane to build edifices rapidly and efficiently
without manual labor.
Schematic view of CC machine
It was originally conceived as a method to construct molds for industrial parts.

5. Behrokh decided to adapt the technology for rapid home construction as a way to
rebuild after natural disasters, like the devastating earthquakes
Using a quick-setting, concrete-like material, contour crafting forms the house's
walls layer by layer until topped off by floors and ceilings set in place by the crane.

6. The system calls for the insertion of structural components, plumbing, wiring,
utilities, and even consumer devices like audiovisual systems as the layers are
built.
Khoshnevis claims that his system could build a complete home in a single day.
The machine is electrically powered crane would produce very little construction
material waste.
Contour crafting could significantly reduce environmental impact

7. AUTOMATED CONSTRUCTION IN JAPAN
• 89 single task construction robots
• 11 different automated construction systems
Concrete Surface Treatment Robot
This robot
absorbs
the water
which
remains
after
concrete
has been
set.

8. Big-Canopy high-rise pre-cast concrete construction system. Used to construct the
26 storey pre-cast concrete 30,726m2
building in Japan. for the frame erection.
The system realized a 60% reduction in labor requirements

9. ICF(INSULATING CONCRETE FORM) HOMES
Insulating Concrete Form (ICF) is a system of formwork for reinforced concrete
that stays in place as a permanent interior and exterior substrate for walls, floors,
and roofs.

10. Concrete Filling

11. Insulation

12. This type of construction mainly used in U.S countries

13. CONSTRUCTION BY CONTOUR
CRAFTING

14. Portion Due to If Automated by CC
20%-25% Financing Short project length and control of
time to market will dramatically
reduce this cost
25%-30% Materials Will be a wasteless process
45%-55% Labor Will be significantly reduced
If constructed by CC method…….

15. Plastic Parts

16. Building Various Surface Slopes

19. CC Building Machine

20. A STRAIGHT WALL BUILDER

22. CONVENTIONAL STRUCTURE CONSTRUCTION

23. CC Machines used in Utilities
Reinforcement
Plumbing
Electrical Works
Flooring

24. Automated Painting

25. FREE-STANDING OBJECTS / INDUSTRIAL PARTS
