6. ACTIVITIES PERFORMED
• The activities here indicates the sequential steps and process to
be carried out from the beginning to the end of the project
completion along with the fulfillment of the standards and the
time required for each activity. Some of the major activities
performed are marking ,form work, reinforcement
foundation(raft),concreting, masonry, plastering, painting and
other finishing works with different standards and textures.

7. 1. MARKING
• Site marking is one of the starting point of your construction.
• In this activity your Engineer and Masonry vendor will identify pillar
placements.
• Once column placement is identified based on soil condition earth work
will start.
• Engineer will mark the area for the foundation. Earth workers will dig
marked area
• Depending on soil condition depth of excavation will vary.
• Some people perform pooja before starting this marking.

8. a. COLUMN MARKING

Department of Civil Engineering
Fig.1: shows the column marking done with exact
dimensions provided as per the plan/design.
I. Column marking is one of the
most important part before the
construction takes place.
II. Because it defines the specific
location for the column to go
up till the final floor.

9. b. METER LINE MARKING
• One meter line is a line drawn on the column/masonry structure .
• This one meter line is marked with reference to the RL of the base.
• The meter line marking is done to get accuracy in height dimensions and
for easy finishing and also for shuttering purpose.

10. FORMWORK (SHUTTERING)
• Formwork in concrete construction is used as a mould for a structure in which
fresh concrete is poured only to harden subsequently. Types of formwork for
concrete construction depends on formwork material and type of structural
element.
• The construction of formwork takes time and involves expenditure up to 20 to 25%
of the cost of the structure or even more.
• Timber is the most common material used for formwork. The disadvantage with
timber formwork is that it will warp, swell and shrink.

Timber Formwork:
• Normal sizes of members for timber formwork: Sheeting for slabs, beam,
column side and beam bottom 25 mm to 40mm thick Joints, ledges 50 x 70
mm to 50 x 150 mm Posts 75 x 100mm to 100 x 100 mm .
• Now a days completely timber type of shuttering is replaced by plywood
formwork and steel formwork to yield fast and better finishing in the design
of structures.
Plywood formwork
• Resin bonded plywood sheets are attached to timber frames to make up
panels of required sizes. The cost of plywood formwork compares
favorably with that of timber shuttering and it may even prove cheaper in
certain cases in view of the following considerations: It is possible to have
smooth finish in which case on cost in surface finishing is there. By use of
large size panels it is possible to effect saving in the labor cost of fixing and
dismantling. Number of reuses are more as compared with timber
shuttering. For estimation purpose, number of reuses can be taken as 10 to
15.

13. REINFORCEMENT
Department of Civil Engineering 13
• Reinforcement is the process of providing the steel bars in combination with the
plain cement concrete to make it as a reinforced cement concrete.
• Reinforced cement concrete are preferred over plain cement concrete because steel
bars used in reinforced cement concreting will provide more strength and stability to
the building structures.
• The design of laying of bars is being carried out according to the plan/design .Bar
bending schedule is being done for designing of bars layout and length , by
preparing the bar bending schedule of the preferred plan the amount and quantity of
scrap can be reduced and hence the cost of steel is reduced.

15. CONCRETING
• Concrete is a construction material made from a mixture of cement,
aggregate (sand or gravel), water and sometimes admixtures in required
proportions.
• STEPS IN CONCRETING:
i. Batching
ii. Mixing
iii. Transportation
iv. Compaction
v. Curing
Department of Civil Engineering 15

16. BATCHING
• The process of measuring different concrete materials such as
cement, coarse aggregate, sand, water for the making of
concrete is known as batching.
• Batching can be done in two different ways.
i. Volume Batching.
ii. Weight Batching.
Department of Civil Engineering 16

17. VOLUME BATCHING
• In volume batching the measurements of concrete materials are taken by
volume & On the other hand the measurements are taken by weight in
weight batching.
• It could not be convenient of measuring the solid materials in terms of
volume method hence a forma box is being prepared of dimensions
305mmX305mmX380mm.
• Therefore all the materials required are being batched in required ratio by
using forma box.

19. MIXING
• In this process, all the materials
are thoroughly mixed in required
proportions until the paste shows
uniform color and consistency.
Hand mixing and machine mixing
are the two different methods of
mixing.
• Note: To achieve optimum quality
the materials should be mixed first
in dry condition and then in wet
condition.

20. TRANSPORTATION
• When the mixing is done properly
the freshly made concrete is then
transported to the construction
site, this process is known as
transportation. After that, the
concrete is correctly placed on the
formworks. Concrete can be
transported to the site location in
two ways Manual Transportation
and Mechanical Transportation.
• For large area of concreting
structures the concrete is being
prepared RMC plants with
required grades and proportions
and then it is being transported by
concrete mixing trucks.

22. COMPACTION
• Compaction is the process in
which the air bubbles are
eliminated from the freshly placed
concrete. It is required to increase
the ultimate strength of concrete
by enhancing the bond with
reinforcement.
Department of Civil Engineering 22

23. CURING
• Curing is the process in which the concrete keeps its moisture for a certain
time period to complete the hydration process. Curing should be done
properly to increase the strength of concrete.

24. HACKING
• It is a process of striking a surface with a special tool so as to roughen it to
hold plastering layer tightly, as the proportion of water/cement ratio
changes.
• Hacking is done on both beams and columns. The dimension of the hacking
should be of 2mm in depth and 75mm in length. There must be 80 number
of indents per square feet.

27. CONCLUSION
• The internship is a bridge between the theoretical knowledge and the
practical knowledge .
• Since we students took the internship session in SOBHA DEVELOPERS, we got
an opportunity to work in different parts of construction work which helps us
to gain more knowledge.
• This program played an important role to break the conventional thought that
field works can be only implemented by students who hold a degree or people
who have an experience in building construction.
• We were able to acquire a high level of confidence to deal with problems that
arise in a building construction.
• The engineers helped us in understanding the execution of the plan to the
field, column work , shuttering work , bar bending schedule , detailing of the
building.
• They also helped us to understand the structural plan of the site, architectural
plan , plumbing plan , electrical plan of the site
• Finally we thank all the engineers, project managers , vice president the
SOBHA DREAM GARDENS for giving this opportunity.
