18. Prefabrication

19. It is assembling components and create a building
or structure that was manufactured from a factory
or apart from the place of construction.

20. Need for Prefabrication

21. Need
Shortages of skilled labor
Need for increased construction quality at lower cost
Need to improve construction productivity
Need for more sustainable solution

22. Advantages
High capacity- enabling the realization of important projects
Factory made products
ensures increased accuracy
Shorter construction time- less than half of conventional cast in situ
construction
Independent of adverse weather conditions during construction
Continuing erection
Quality surveillance system
Opportunities for good architecture

23. Cont….
Healthy buildings
Reduced energy consumption
Environmentally friendly way of building with optimum use of materials,
recycling of waste products, less noise and dust etc.
Cost effective solutions for massive structures
savings can be expected:
Formwork 75% less
Scaffolding 75% to 90% less
Wet Concrete 90% less
Reduction in construction time
Safety in construction

24. Increase in the quality of construction.
Reduction of construction waste
Less skilled labor required
Loose Reinforcement
The amount of loose reinforcement on site is reduced by between 80% and 90%.
Larger Clear Spans
Reducing the number of columns
Composite Action
Prestressed precast elements act compositely with an in situ structural screed (topping), combining the
benefits of precast and in situ construction.

25. Which type of concrete commonly
used in prefabricated
Construction?
a. Self Compacting Concrete
b. Light Weight Concrete
c. Nominal Concrete specified in IS 456.
d. Cellular Concrete

27. Disadvantages
Leaks can form at joints in prefabricated components.
Transportation costs may be higher for voluminous prefabricated sections than for the
materials of which they are made, which can often be packed more efficiently.
Large prefabricated sections require heavy-duty cranes and precision measurement and
handling to place in position.
Larger groups of buildings from the same type of prefabricated elements tend to look drab and
monotonous.
Site access and storage capacity
Joint details are predefined
