SITE CLEARANCE:

The very first step is site clearance which involves

removal of grass and vegetation along with anyother objections which might be there in the site

location.

POSITIONING AND LAYOUT:The centre point was marked with the help of a

thread and plumb bob as per the grid drawing. With

respect to this center point, all the other points of

columns were to be decided so its exact position isvery critical.

LAYOUT

EXCAVATION:

Excavation was carried out both manually as well

as mechanically. Normally 1-2 earth excavators

(JCBs) andpoclain were used for excavating thesoil. Adequate precautions are taken to see that

the excavation operations do not damage the

adjoining structures. Excavation is carried out

providing adequate side slopes and dressing ofexcavation bottom


9/17

PLAIN CEMENT CONCRETE (P.C.C):

After the process of excavation, laying of plain

cement concrete that is PCC is done. A layer of 4

inches was made in such a manner that it was notmixed with the soil. It provides a solid base for the

raft foundation and a mix of 1:5:10 that is, 1 part of

cement to 5 parts of fine aggregates and 10 parts

of coarse aggregates by volume were used in it.Plain concrete is vibrated to achieve full

compaction. Concrete placed below ground should

be protected from falling earth during and after

placing. Concrete placed in ground containing

deleterious substances should be kept free from

contact with such a ground and with water draining

there from during placing and for a period of sevenda s.

LAYING OF FOUNDATION

This term includes the portion of the structure below the plint

level as well as the artificial arrangement of concrete blocks,

piles, raft, grillage etc. Which are provided to transmit theloads of the structure (including the dead weight of the

structure itself) to the soil below.

Classification of Foundation :

1. Simple, Shallow and Deep foundation2. Pad /strip type and piled foundation

Purpose of foundation:1. To distributes the loads of the structure over large soil area so as to

avoid over loading of the soil beneath.

2.To load every the sub-stratum and thus prevent unequal settlement.3.To provide a level surface for building and thus increase its stability,

preventing, overturning and instability.

RAFT FOUNDATION


12/17

COLUMN:

A column or pillar in andstructural engineering is a vertical

structural element that transmits, through compression, the

weight of the structure above to other structural elements

below.

BEAM:-

A structural member of reinforced concrete, placed

horizontally over openings to carry loads. A bar is actedupon by forces or couples or both in axial plane, which

cause bending of bar, is known as a beam.

Types of beam:

Singly reinforced beam

Doubly reinforced beam


13/17

SLAB:

A concrete slab is a common structural element of modern

buildings. Horizontal slabs of steelreinforced concrete,

typically between 10 and 50 centimeters thick, are mostoften used to construct floors and ceilings, while thinner

slabs are also used for exterior paving.


14/17

BRICKWORK:

Brickwork is masonry done with bricks and mortar and is

generally used to build partition walls. In our site, all the

external walls were of concrete and most of the internalwalls were made of bricks. English bond was used and a

ratio of 1:4 (1 cement: 4 coarse sand) and 1:6 were used

depending upon whether. The wall is 4.5 inches or 9 inches


15/17

PLASTERING:

At site plastering was done and bricks work as well as

stone work and other vertical part of building surface. At our

site the ratio for plaster is taken as 1:6 for half brick

masonry and 1:3 for columns and bottom are slab. Mortar

used for plastering was cement, sand, mortar. Fine sand

was used for preparing mortar. It was not fine so that it canpass more than 5% through a 50-mesh sieve.

Plastering was done only the internal surface of the room.

At external surface there was stone masonry. Plastering

thickness was 10 mm. on brickwork and 15 mm. on stonework some place cement coating was used.
