It is a ppt based on my training civil report on shuttering.

2. Introduction:
 Sambhavna offers many flats ranging from 520 sq ft
to 1520 sq ft in 9 & 12-storey towers.
 Luxuriously planned with the most amicable
amenities, boasts of 60% open green spaces with
most apartments facing the central garden.

3. Project Snapshot :
 The project is located off the Lucknow Rae
Bareilly road and is 10 kilometres (km)
away from Amausi Airport and 11 km from
Hazratganj. The project has good road
connectivity. The project is targeted to the
service class in the region.

4.  A wide range of lifestyle amenities such as a
club, a swimming pool, indoor and outdoor sport
facilities, central park and shopping complex are
available.
 There are in all 17 towers with 14 towers having
12 floors and remaining 3 towers having 11
floors each, internal roads were 12 m wide.
 Completion Date:2013

6. Equipments used:
Transit mixer:
 It is device that homogeneously combines
cement, aggregate such as sand or gravel, and
water to form concrete.
 Transit mixer is truck mounted by a revolving
drum to mix the components. For smaller
volume works portable concrete mixers are
often used so that the concrete can be made at
the construction site.

8. Back hoe:
 A backhoe, is a piece of excavating
equipment or digger consisting of a digging
bucket on the end of a two-part articulated
arm.
 They are typically mounted on the back of
a tractor or front loader. The section of the
arm closest to the vehicle is known as the
boom, and the section which carries the
bucket is known as the dipper or dipper stick.

10. Concrete Pump:
 The main type of concrete pump is either
mounted on a truck and known as a truck-
mounted concrete pump or placed on a
trailer, and it is commonly referred to as a
line pump or trailer-mounted concrete pump.
 This pump requires steel or rubber concrete
placing hoses to be manually attached to the
outlet of the machine.

16. Procedure
Excavation:
 Excavation was carried out both
manually as well as mechanically.
 Adequate precautions are taken to see
that the excavation operations do not
effect the adjoining structures.

17. P.C.C:
 After the process of excavation, laying of plain
cement concrete that is PCC is done. A layer of
75 mm 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 1:3:6 that is, 1 part of cement to 3
parts of fine aggregates and 6 parts of coarse
aggregates by volume were used in it.

18. LAYING OF FOUNDATION
 At the site, Raft foundations was used to spread
the load from a structure over a large area,
normally the entire area of the structure.
Normally raft foundation is used when large
load is to be distributed and it is not possible to
provide individual footings.
Raft foundations have the advantage of
reducing differential settlements as the concrete
slab resists differential movements between
loading positions.

19.  They are often needed on soft or loose soils
with low bearing capacity.
 Raft Foundation had a thickness of 750 mm.
 Bars of 25 mm to 16 mm were used and chairs
were used.

21. FORM WORK
 Forms or moulds or shutters are the
receptacles in which concrete is placed,
so that it will have the desired shape or
outline when hardened.
 Once the concrete develops adequate
strength, the forms are removed. Forms
are generally made of the materials like
timber, plywood, steel, etc.

23. Scaffolding/props used:
 Scaffolding is a temporary structure used to
support people and material in the construction
or repair of buildings and other large structures.
 It is usually a modular system of metal pipes or
tubes, although it can be from other materials.
 The key elements of a scaffold are standards,
ledgers and transoms.

25. CONCRETING
 Type of Cement Used :P.P.C (A.C.C)
 Grade of concrete in slabs and beams :M-20
 Grade of concrete in coloumns:M-30
 Grade of concrete in P.C.C work:M-10
 Grade of concrete in Raft foundation:M-25

26.  Concrete was made at the site only at
the batching plant.
 From there it was carried upto the site
with the transit mixer.
 Capacity of a transit mixer :6m3
 Aggregates sizes :20 mm ,10mm
 Fine aggregate (sand):zone 2

27. REINFORCEMENT
 Fe-500 grade of steel was used.
 High strength deformed bars conforming to
IS: 1786 ,grade Fe 500, indicate yield
stresses 500 N/mm2 are commonly used.

29. Column
 Total no. of columns in a floor was 69 , in
which 64 have dimension 750*250 and
remaining 5 columns having dimension
600*250.
 There were 10 bars used in the columns in
which the corner bars were of dia. 25
mm ,and the remaining were 20 mm dia. till
5 th floor.
 6 th to 9 th floor bars of dia. 20 mm and 16
mm were provided respectively in the
corner and in the middle.
 From 9 th onwards till the end the bars of
dia. 16 mm and 12 mm were provided.

31. Ring/Tie bars:
 8 mm dia. bars were used as ring.
 The larger ring was of dimension 650*150 mm
which holds the corner bars and the smaller ring
was of dimension 350*150 which holds the inner
bars.
Spacing between the rings:
 The spacing between the top and the next ring
was 80 mm and also the same spacing was
provided for the bottommost and the ring above
it.
 Rest all the spacing between the rings was
120mm.

33. Beams:
 Beams were of sizes 230*400,small beams of
size 230*160 was also provided.
 Main Reinforcement: Mostly bars of dia 25,20
and 16 mm were provided.
Shear Reinforcement:
 Stirrup was of dia. 8mm.
 Stirrups were provided for the shear
reinforcement ,1 st stirrup is at 40 mm from face
of the supporting member.
 Spacing of the stirrup was upto 2*(dia of the
main bar)

35. Slab:
 Main bars used were of 12 mm at the top and
also at the bottom.
 Chairs were provided at different locations to
provide the spacing required between the top
and bottom reinforcement.
 Thickness of the slab was 100 mm.
 Note: No shear reinforcement is provided in the
slab.

37. Cover block:
 Cover blocks are placed to prevent the steel
rods from touching the shuttering plates and
there by providing a minimum cover and fix the
reinforcements as per the design drawings.
 Covers should be made of cement sand mortar
(1:3). Ideally, cover should have strength similar
to the surrounding concrete, with the least
perimeter so that chances of water to penetrate
through periphery will be minimized.

40. SAFETY NETS

41. CONCLUSION
 This training is comprehensive in filling the gap
between the theoretical & practical studies
 At the site there was a good management
system between the contractor, the consultant,
and the client.
 I found that there was good understanding
between the supervisor and the workers,
though works are interdependent but there
were no contradiction between them.
