Introduction
Logical Approaches
Optimizing housing solutions• Affordable housing is a term used
to describe dwelling units whose
total housing cost are deemed
“Affordable” to a group of people
within a specified income range
• The technology to be adopted for
housing components should be
such that the production and
erection technology be adjusted
to suite the level of skills and
handling facilities available under
metropolitan, urban and rural
conditions.
Economy in designOptimal space in the design Energy efficiencyCost effective
construction systems
Effective mechanism
Prefabrication as applied to Low Cost Housing
Advantages
• Components are readymade, self supporting, shuttering and scaffolding is eliminated
with a saving in shuttering cost
• The mould for the precast components can be used for large number of repetitions
thereby reducing the cost of the mould per unit
• Time is saved by the use of precast elements which are casted off-site during the
course of foundations being laid.
• types of components are produced repeatedly, resulting in increased productivity and
economy in cost too
• work at site is reduced to minimum, thereby, enhancing the quality of work, reliability
and cleanliness.
• The execution is much faster than the conventional methods
Slide No. 2
Concept of prefabrication: Construction techniques & Materials
In Walls
• In Actual const., Wastage of
material poor quality.
• Increasing the size of wall blocks
will prove economical due to
greater speed and less mortar
consumption, which can be
achieved by producing low density
bigger size wall blocks using
industrial wastes like blast furnace
slag and fly ash.
• Several prefabrication techniques
have been developed and
executed for walls but these
medium and large panel
techniques have not proved
economical for low rise buildings as
compared to traditional brick work
Non erodable mud
plaster
• Made non erodable by the
use of bitumen cutback
emulsion containing mixture of
hot bitumen and kerosene oil.
• The maintenance cost is low
due to enhanced durability of
mud walls
Fly –Ash sand lime bricks
• After reactions between lime
and fly ash, calcium silicate
hydrates are produced which
are responsible for the high
strength of the compound.
Solid concrete and stone
blocks
• Suitable in areas where
stones and aggregates for
the blocks are available
locally at cheaper rates
Construction techniques & Materials
In Floor and Roof
Use of standardized and
optimized roofing components
where shuttering is avoided
prove to be economical, fast
and better in quality.
Some of the prefabricated
roofing/flooring components
found suitable in many lowcost
housing projects are:
• Precast RC Planks
• Prefabricated Brick Panels
• Precast RB Curved Panels
• Precast RC Channel Roofing
• Precast Hollow Slabs
• Precast Concrete Panels
• L Panel Roofing
• Trapezon Panel Roofing
• Un reinforced Pyramidal
Brick Roof
Precast RC plank roofing
system
Prefabricated brick panel roofing system
(a) Prefab brick panel (b) Partially precast joist
Precast curved brick
arch panel roofing
Precast RC channel roofing Precast hollow
slabs roofing
L- Pan roofing Trapezonpan roofing flooring Un-reinforced
pyramidal brick roof
Construction techniques & Materials
Other uses of prefabrication
(a) Thin precast RCC lintel
(b) Doors and windows
• Innumerable types and sizes of doors
and windows used in single and similar
buildings.
• This involves the use of additional skilled
labour on site and off site and also
wastage of expensive materials like
timber, glass etc. Economy can be
achieved by:
(i) Standardizing and optimizing
dimensions;
(ii) Evolving restricted number of doors
and window sizes; and
(iii) Use of precast door and window
frames
Materials used:- (BMTPC- Building Materials & Technology Promotion
Council, Govt. of India)
 Conventional building materials like burnt bricks, steel and cement are higher in
cost, utilize large amount of non-renewable natural resources like energy, minerals,
top soil, forest cover, etc,.
 The continued use of such conventional materials has adverse impact on economy
and environment.
 Environment friendly materials and technologies with cost effectiveness are,
therefore, required to be adopted for sustainable constructions which must fulfil
some or more of the following criterion:
• Not endanger bio-reserves and be non-polluting.
• Be self sustaining and promote self reliance.
• Recycle polluting waste into usable materials.
• Utilize locally available materials.
• Utilize local skills, manpower and managing systems.
• Benefit local economy by being income generating.
• Utilize renewable energy sources.
• Be accessible to people.
• Be low in monetary cost.

CONCLUSION
 The main advantage for the Prefabrication construction is to reduce Manpower, Maintenance, reduces time and cost.
 It takes one step above the construction industry.
 Though pre cast members are heavy and may have problems in lifting, transporting and connecting at site, an over all savings
of about 30%-50%cin cost of project can be achieved.
 Prefabricated components speed up construction time, resulting in lower labour costs.
 The work is not affected by weather delays.
 Prefabrication is usually applied in structures which are used repeatedly ; mass housing, sheds, bus stands, security cabins, site
offices and road bridges.
 In the future, the prefabrication system will be used in 70% of construction sites due to the fast growing population and
economy.

Concept of prefabrication: Construction techniques & Materials In Walls • In Actual const., Wastage of material poor quality. • Increasing the size of wall blocks will prove economical due to greater speed and less mortar consumption, which can be achieved by producing low density bigger size wall blocks using industrial wastes like blast furnace slag and fly ash. • Several prefabrication techniques have been developed and executed for walls but these medium and large panel techniques have not proved economical for low rise buildings as compared to traditional brick work Non erodable mud plaster • Made non erodable by the use of bitumen cutback emulsion containing mixture of hot bitumen and kerosene oil. • The maintenance cost is low due to enhanced durability of mud walls Fly –Ash sand lime bricks • After reactions between lime and fly ash, calcium silicate hydrates are produced which are responsible for the high strength of the compound. Solid concrete and stone blocks • Suitable in areas where stones and aggregates for the blocks are available locally at cheaper rates
  • 5. Construction techniques & Materials In Floor and Roof Use of standardized and optimized roofing components where shuttering is avoided prove to be economical, fast and better in quality. Some of the prefabricated roofing/flooring components found suitable in many lowcost housing projects are: • Precast RC Planks • Prefabricated Brick Panels • Precast RB Curved Panels • Precast RC Channel Roofing • Precast Hollow Slabs • Precast Concrete Panels • L Panel Roofing • Trapezon Panel Roofing • Un reinforced Pyramidal Brick Roof Precast RC plank roofing system Prefabricated brick panel roofing system (a) Prefab brick panel (b) Partially precast joist Precast curved brick arch panel roofing Precast RC channel roofing Precast hollow slabs roofing L- Pan roofing Trapezonpan roofing flooring Un-reinforced pyramidal brick roof
