CONSTRUCTION METHODS
Excavation
It is one of the most important activities of the
construction industry. It starts form digging pit and
continues up to the handling over the site.
Excavation is required for various kind of
activity like:-
1.Foundation of the building.2.Plinth and beam work.3.Construction of the basement of the building4.Laying out water and drainage pipe-line.5.Construction of compound wall.
Requirement to start excavation.
It is very much necessary to understand the various
layer of soil below the ground as depth of various layer
keeps on changing from location to location. It is one of
the main factor on which design of foundation is based.

Methods of excavation:-
With the help of poclain:It is used when huge volume of soil is to be
excavated.
With help of JCBIt is one of the most common equipment used for
excavations.
Labour power.When small volume of soil is to be excavated,
labour are used for it.

FOUNDATION
On our site we had column foundation. Before
starting column foundation approximately leveled and
the center of footings were marked, according to the
foundation plan.
Every civil engineering structure is divided into
two parts:
Sub StructureSuper Structure
Sub structure is a term. Which is also called as
foundation. Foundation is that part of structure the most
important part of the structure, which stays below the
gorund and transmits the total load of the structure on to
the foundation base.
Necessity and purpose of foundation :
Foundation transfer the load to the soilIt supports the structure against wind, ran etc.To provide a leveled base for the super structure to
rest.

Foundation on the bases of the depth can be classified
as:
Shallow foundationWhen it is possible to have a foundation at
reasonable shallow depth, the foundation is termed as
shallow foundation or when the depth of doundation is
less than or equal to the width of the foundation it iscalled shallow foundation.
The different types of shallow foundation are:-
Shallow footingCombined footingraft footingDeep foundation
when the depth of foundation is more than the width
of the foundation then its termed as deep foundation.
Mostly for towers deep foundation is prepared. Pile
foundation is a type of deep foundation.

Pile Foundation:-Pile foundation is a type of foundation, which is
done when the soil available, is soft and marshy or the
hard strata is at great depth. Pile foundation is designed
such that the load is transmitted by resting it on hard
strata or by friction between the pile and soil in contact.
Piles may be cast-in-situ or precast. At our site cast-
in-situ piles were used. Piles vary in shape and size. They
are available in shapes like circle, hexagonal, etc. and of
different diameter 300mm to 1200mm and more.

Plinth works
Plinth work is one the most important works and
needs proper care while construction. It is said that
efficiently of a civil engineer is judged here, as mistake
committed here cannot be rectified. Plinth wall function
as a retaining wall.
Plinth work involves following activities.
Excavation up to the depth of plinth requiredbelow ground level
Rubble soling of 15mm below ground levelCompaction of rubble solingP.C.C of 100mm over rubble solingReducing the height of chipping extra portion.Casting of tie beam.Casting of Column and stub columnBrick masonry up to plinth level.Filling of murrum and stone dust and murrum.Compaction of the rubble soling.Anti-termite treatment given to plinth area.P.C.C work to be done over it for flooring.

MEMBERSColumns
Column are one of the most important vertical
member of R.C.C structure as they support beam and
slab. It is column that takes the load of beam and slab
and transfers I to the foundation. If the column fails t
take the load there are high chances for the building
collapse. Column not only bears the dead load of the
beam and slab but also has to bear gravitational force,
wind pressure & earthquake pressure.
Column can be casted in various shape and sizes
depending upon architectural and sizes depending uponarchitectural requirements and load bearing capacity of
it.
Reinforcement in column:
It should be as per drawing provided by R.C.CConsultant.
Minimum reinforcement should be 0.8% of the C/Sarea.
Maximum reinforcement should be 8% of the C/Sarea.
Starters:-

SHREE PRAGATI DEVELOPERS CIVIL ENGINEERING
FR. AGNEL POLYTECHNIC, VASHI
Before casting of column it is essential to cast startersof at least 4 of height.
Advantage of casting starters:-
Position of column can be easily fixed as they are ofjust 4 of height.
Formwork for column:-
Formwork for column are erected on the next day of
the casting of the starters. Formwork can be either of
wood or M.S plates. Before erecting of formwork they
are well oiled. Once the formwork is erected they are
supported by joist on sides in order to prevent bulging of
column. Clamps (shikhanjas) support formworks in
angles.

Concreting Of Coloumn:-
The desired grade of concrete is prepared in
concrete mixer and is transported up to the column. Then
with the help of labours the concrete is pored in to
formwork with the help of mortar pans. While pouring
concrete a person with vibrator has to concrete is
properly vibrated.
Deshuttering:-
It should be done after 24hrs. only.
Hacking :-
Once the column is casted then it is very much
necessary to provide hacking so that when the plaster is
applied on it. It holds the plaster firmly.

Fixing:-
Reinforcement shall be accurately fixed by any
approved means maintained in the correct position as
shown in drawing by using spacers, cover block etc to
prevent displacement during placing compaction of
concrete.
Covers to reinforcement:-
Cover blocks, which are generally of cement mortar,
shall used to ensured the required cover for
reinforcement. To provide necessary cover for
reinforcement at any section only single cover block
shall be used.
Covering is provided to the reinforcement sothat
due to atmosphere action the reinforcement does not get
corroded and therefore the strength cannot be reduce of
the R.C.C Member.On out site cover for column was 40mm and for
beam it was 25mm

BEAM & SLAB
Beam and slabs are horizontal member of the
structure. The live and dead load is taken by the slab and
is passed on to the beam, which in return transfer the
load to the column.
Formwork for slab and beam:-
First of all column cap is marked on all the columnwith the help of level tube.
After fixing column cap beam bottom is erected. Beambottom is basically a wooden plank rested on over
column cap.Once the beam bottom is erected it is supported over
the props in order to avoid point load.
The formwork of the slab and beam is well oiled.

the places. While another person level the concrete withthe help of float.
Deshuttering of slab:
Once the concrete is hardened, sides of the slab can
be removed after 224 hrs. however bottom of slab and
beam is removed after 7days and 14day respectively.
Curing:-
Curing should be done 4-5 times for 14days.
Checks for slab and beam during casting
Height from slab to slab should be checked beforeconcreting.
Shuttering of the slab should be properly leveled.Width and depth of beam should be checked.Reinforcement of beam should be checked with
respect to top bars and bottom bars.

MASONRY
It is required at many places like construction of
foundation, wall, etc. in framed structure no load is taken
by masonry. The role played by masonry in framed
structure is just a create a partition.
Classification of masonry:-1.Stone Masonry2.Brick Masonry
Stone masonry is further classified as rubble
masonry and ashlars masonry, where brick masonry is
classified as per bonds like:-

SHREE PRAGATI DEVELOPERS CIVIL ENGINEERING
FR. AGNEL POLYTECHNIC, VASHI
1.All the brick should be soaked in water before usingthem for masonry work.
2.First of all layout was made by single layer of brick ona bed of mortar.
3.Once the first layer was approved, layer above it wasdone and checked by line dori.
4.Cement mortar was made by using ration of 1:6. Brickwall at a height of 1.5m.
5.Then curing was done 2-3 times a day for 3-4 days.Dos for the brick masonry
1.Brick should be good and of uniform size, shape andcolor.
2.Before using for construction work it should be fullyimmersed inwater for two to three hours.
3.Brick should give metallic ringing sound when struck.4.Curing should be done at least 7-10 days for brick
wall.
Donts for the brick masonry:
1.Unburnt and over burnt brick should not be used.2.Joints should not exceed a thickness of 10mm.3.Broken bricks should be avoided in masonry work as
far as possible.

Open wiring:
The process in which the wiring is carried out over
the painted surface is known as open wiring. The main
advantage of open wiring Is that is facilitates case in
repair works. It can be further classified in to two
groups:-
1.Pipe wiring2.Open frame wiring3.Close frame wiring
1.Pipe wiringIn this type of wiring wires are supported with wire,
which runs over the wall. In this type of wiring repair
work are difficult. As the pipe is to be cut. Thus this type
of wiring is not used at present.
2.Open frame wiringIn this type of wiring the wires are supported over a
wooden strip, which act as a frame. Due to shabby
appearance this type of wiring is avoided.

3.Closed frame wiringIn this type of wiring a closed frame is use. Which
can be opened for repaired works. Due to better
appearance and ease in repair work this type of open
wiring is maximum use.
4.Concealed wiringThe wiring, which is hidden within the plaster
surface, is known as concealed wiring. This type of
wiring facilitates better appearance and is thus maximum
in use. It even facilitates safely from damage in industrial
area. But this type of wiring is difficult to repaired.

For external plaster, scaffolding was built in
advance. Before plastering the surface is cured for at
least 3 days. Level dots are marked for thickness of12mm at a distance of 2m to 15m intervals. They are
used as reference pint the points are transferred with
plumb bob. Nylon threads were tied near all the edges
and window frames of external wall so that thickness of
plaster and line of edges are controlled. Before starting
the plaster cement slurry was applied.
First coat or base coat:
In the first coat proportion used for cement mortar is
1:4. Thickness of the coat was approximate 12mm. the
layer was not finished and was kept rought to provide
good bonding with second coat. The coat was cured for 3
days before the second coat is started.
Second coat or final coat:
In this second coat proportion used for cement
mortar is 1:6. Thickness of second coat was
approximately 8mm. during this coat sponge is used to
get fine grains of sand.

Various drawing use for construction of A building
Right from the start of any project a engineer has to
deal with a number of plans. The drawing give a brief
idea about the building. The drawing are the giving by
the architect i.e all the elevation drawing and the
consultant should be check cleared by some experienced
person. If at all there is some mistake in the plan it will
eventually create a problem at site. As the engineer
construct the building as per the drawing
The various drawing used are:
General drawingCenterline planFoundation and column planPlinth beam planVarious floor planSectional drawingElevation drawing (both side)Categories of labour

CONCLUSION
The training period of six months has helped me get
familiar with the site, thus giving me an insight of future
professional career. To carry project at out site according
to the specification & to maintain the required stand is
really a job, which needs a great amount of hard work &
experienced to control & maintain the progress of the
work.
This training period has made me more responsible
and confident in my approach towards our future. Thus I
would conclude that we are well equipped with practical
knowledge and not only theoretical knowledge and we
are fortunate one among the few. And also we are
prepared to face the world of construction any time in the
future.
