14. Laying of P.C.C. (Plain Cement
Concrete):- After the process of
compaction and levelling, laying of
plain cement concrete that is PCC is
done. A layer of 100mm thick PCC of
grade M10 with 100mm projections was
made in such a manner that it was not
mixed with the soil. It provides a solid
base for the raft foundation and a mix of
1:4:8 that is, 1 part of cement to 4 parts
of fine aggregates and 8 parts of coarse
aggregates by weight were used in it.
Plain concrete is vibrated to achieve full
compaction.
Methodology Of Work
Total quantity of PCC required: 120 m3

15. Waterproofing:
The roof covering materials, siding,
foundations, and all of the various penetrations
through these surfaces need to be water-
resistant and sometimes waterproof.
APP Membranes
APP Membranes:
APP Waterproofing Membranes are
mostly used to prevent leakage in
various areas.
Methodology Of Work
Non-woven Fabric
Non-woven fabric is a fabric-like material
made from long fibers, bonded together
by chemical, mechanical, heat or solvent
treatment.
This fabric is used over APP membrane to
prevent its puncturing due to
reinforcement and concrete.

16. Methodology Of Work
50mm Thick Screed:
It protects the waterproofing membrane
from puncture if any by rebar's.

19. Retaining wall:
A retaining wall is a structure designed
and constructed to resist the lateral
pressure of soil when there is a desired
change in ground elevation that exceeds
the angle of repose of the soil.
Methodology Of Work
Laying of Beam and Slab:
A structural member which supports
lateral load and resist bending is known as
beam. Slabs are plane structural member
whose thickness is quite small as
compared to its other dimension. Slab
support mainly transverse loads and
transfer them to end supports by bending
action in one or more directions.

Is a vertical access that moves up and
down inside a building and carries people
from one floor to another floor. The lift
frame is made of R.C.C. and construction
method is same as other member.
Stair
A series of steps or flight of steps that go
from one level to another is called stair.
The form work can be made up with
plywood or framing lumber.

21. Methodology Of Work
What Is the Difference Between Shuttering and Formwork?
Shuttering and formwork are both terms used to describe the
process of creating a mould in which concrete can be poured and
contained as it hardens. Shuttering usually refers to the process of
using plywood to form the mould, while formwork is something of a
broader term that is used to denote the forming process using a wide
variety of materials. Shuttering and formwork both accomplish the
same essential task, but the materials used to accomplish this task
can vary. Sometimes there is no differentiation made between the
two terms, and in some cases, shuttering may be considered one
specific type of formwork.

22. Methodology Of Work
Filler Board:
This is capable of expansion and contraction
which occurs with seasonal variations in
temperature and are generally placed
between two slabs or columns. Features of
filler board are affordable, effective, and
reliable
Filler Board
Waterbar:
The function of waterbar is to seal the joint
against water penetration. Waterbars may be
necessary where the joint is subject to
groundwater pressure or where the method of
construction makes it difficult to accurately
seal the surface cavity, and where it is very
essential that there shall not be any risk of
penetration of water.
Waterbar

23. Methodology Of Work
Waterbars may be of natural and
synthetic rubber, polyvinylchloride (PVC)
or metal. The strips shall be supplied in
uniform lengths of 2.5 to 3.5 m at the
option of the manufacturer, unless
otherwise ordered

Concrete.

25. Quality Control and Testing
Various tests which are done on different materials are listed
below:
• Slump Test
• Compressive Strength of Concrete
• Weight of Steel
• Silt Content
• Grading of Aggregate
• Impact Value Test
• Compressive Strength of Brick
• Water Absorption Test
• Dimensional Tolerance
• Determination of Moisture Content by Calcium Carbide
Method
• Core Cutter Method

26. Quality Control and Testing
Determination of moisture content by using calcium carbide.
This test is done to determine the water content in soil by calcium carbide method
as per IS: 2720 (Part II) – 1973. It is a method for rapid determination of water
content from the gas pressure developed by the reaction of calcium carbide with
the free water of the soil. From the calibrated scale of the pressure gauge the
percentage of water on total mass of wet soil is obtained and the same is converted
to water content on dry mass of soil.
Apparatus required :-
i) Metallic pressure vessel, with a clamp for sealing the cup, along with a gauge
calibrated in percentage water content.
ii) Counterpoised balance, for weighing the sample.
iii) Scoop, for measuring the absorbent (Calcium Carbide).
iv) Steel balls – 3 steel balls of about 12.5mm dia. and 1 steel ball of 25mm dia.
v) One bottle of the absorbent (Calcium Carbide).

27. Quality Control and Testing

28. Quality Control and Testing
Procedure to determine Water Content In Soil By Calcium Carbide Method
• Set up the balance, place the sample in the pan till the mark on the balance
arm matches with the index mark.
• Check that the cup and the body are clean.
• Hold the body horizontally and gently deposit the leveled, scoop-full of the
absorbent (Calcium Carbide) inside the chamber.
• Transfer the weighed soil from the pan to the cup.
• Hold cup and chamber horizontally, bringing them together without disturbing
the sample and the absorbent.
• Clamp the cup tightly into place. If the sample is bulky, reverse the above
placement, that is, put the sample in the chamber and the absorbent in the cup.
• In case of clayey soils, place all the 4 steel balls (3 smaller and 1 bigger) in the
body along with the absorbent.
• Shake the unit up and down vigorously in this position for about 15 seconds.

29. Quality Control and Testing
• Hold the unit horizontally, rotating it for 10 seconds, so that the balls roll
around the inner circumference of the body.
• Rest for 20 seconds.
• Repeat the above cycle until the pressure gauge reading is constant and note
the reading. Usually it takes 4 to 8 minutes to achieve constant reading. This is
the water content obtained on wet mass basis.
• Finally, release the pressure slowly by opening the clamp screw and taking the
cup out, empty the contents and clean the instrument with a brush.

30. Safety Measure and Campaign
• In Civil engineering construction
project, accidents cannot be avoided.
• A mishap can happen any time and
unexpectedly during construction.
• About 80 percent of accidents are
mainly caused due to unsafe
practices and shear negligence of the
workers.
• Safety measures are necessary to motivate and
encourage the workers to work at the given site or
industry without any fear, tension or worry in
mind about his security of life.
• Good safety measures are essential to
increase the output of work by
generating safety free environmental
sense of contentment among the
workers.

• Producing the Bricks by Using Enzymes.
• The EN-2 Enzyme is a synergistic mixture of enzymes, coenzymes, binders,
catalysts, wetting agents, surfactants and water. It is non-toxic and non
combustible. It does not harm humans, animals, fish or vegetation under
normal use and is totally biodegradable process. EN-2 have been tailored to
provide the "lock" for numerous soil and other organic materials and
promote the desired alteration of their properties, causing a rapid
cementation process to occur.
The Advantages of Using EN-2 in the Brick Manufacturing
• Reducing the cement quantity up to 50%.
• Reducing the cost of manufacturing the brick.
• Reducing water absorption in the brick.
• Maintaining the strength of the product.
• Reducing water use during the process.
