ADVANCED CONSTRUCTION TECHNIQUES
PRE-FABRICATION
CONTOUR CRAFTING
PRE-FABRICATION
Practice of assembling the components of a building in a factory and then transporting them to the construction site for installation
TYPES OF PRE-FABRICATED UNITS
Structural insulated panels (SIPs)
Insulating concrete forms (ICFs)
Prefab foundation system
Steel framing
Concrete framing
Large - modular system
PROCESS OF PRE-FABRICATION
Industrial construction methodTwo stages:
1.Manufacture of components at factory2.Erection on the site
Precast units cast in advance and given time to harden
Units are concreted in stationary moulds Provided with ordinary reinforcement or pre
stressed with cables or wires Various components have to be erected
appropriately assembling them together
ADVANTAGES OF PRE-FABRICATION
Construction time is shortened
Quantities of material required are reduced
Less manpower
Better quality of product
No weather restrictions for construction
DISADVANTAGES OF PRE-FABRICATION
Leaks can form at joints
Transportation cost may be higher
Heavy duty cranes are required
Careful measurement and handling is needed
Structure may look drab and monotonous
CONTOUR CRAFTING
It builds large scale three-dimensional parts by depositing paste materials layer by layer at unprecedented speed and with superior surface quality
PROCESS OF CONTOUR CRAFTING
Method of layered manufacturing
Uses polymer, ceramic slurry, cement, and a variety of other materials
Mixes to build large scale objects with smooth surface finish
Done by method of extrusion
ADVANTAGES OF CONTOUR CRAFTING
Total material use is less.
Less transportation of materials, equipments and people.
Less noise exposure.
Increased structural strength and durability
Increased seismic safety
DISADVANTAGES OF CONTOUR CRAFTING
Unsuitability of the available automated fabrication technologies
Smaller ratio of production quantity
Economic unattractiveness of expensive automated equipment
Managerial issues.
CONCLUSION
Cost and time effective
Less manpower required
Good quality construction
Reducing accident and material wastage
Eco-friendly methods
