ACKNOWLEDGEMENT
It is well known fact that theory alone can bear no fruits for
Engineers so the practical training is must.
The P.T.U has done a lot in this report to its students acquainted with the field of environment by providing them six Month Industrial training. I am very grateful to P.T.U for the Opportunity provided to us. I am working on the project Godreg agrovet pvt ltd.This project is undergoing at Khanna(Ludhiana).
My due thanks also goes to the Site Engineer: Mr Jitendra kumar for employing me as a training engineer and helping me to orient myself in the company for six months.
I sincerely thank ER. Paramjit singh for their kind assistance for six months industrial training. I am gaining valuable and latest mode of training under the experienced technical team of KUWAR BUILDER.
MY SIX MONTH TRAINING
THE BEGINNING:
My six month training was at KUWAR BUILDER & DEVELOPER at KHANNA. I went at my site, where on first few days our site incharge allows as to study the detail drawing and the project work taken place already. After the study of structure I was awarded the work of site supervision, quality control and the safety, health and environment. Under site supervision I undergo various aspects of building like execution of the construction and finishing work its procedures, steps and some practical problems faced during execution. Under quality control all the test to be conducted before, during and after the execution of work was done to assure the client for best quality work.
SITE DETAILS:
The site is at KHANNA. The cost of the project is estimated to be around 50 corers (the structural cost 30 corers and finishing cost 20 corers). The proposed structure consists of a 4 storey building. (1 Basements, 1 ground floors, 2 upper floors).The site covers the area of 10,000 sq m. Total build up area is 70,000sq m and open area 3,000sq m. Total floor area is 50,000sq m. supper structure and 20,000sq m. Basements).Height of the Super structure is 30metre (98.425 feet). . The structure is designed as earthquake resistant structure.
CONSTRUCTION OF RAFT FOOTING
A raft or mat foundation is a large concrete slab used to interface columns in several lines with the base soil. It may occupy the entire foundation area or only a part of it. A raft foundation may be used where the base soil has a low bearing capacity or the column loads are so large that more than 50 percent of the area is covered by conventional spread footings. Raft footing consists of beams and slabs spanning in both directions.
RAFT FOUNDATION
SPECIFICATIONS OF RAFT FOUNDATIONS
1. All the foundations are to be placed at the level of -18.045meter from N.G.L.
2. All the steel to be used should be of grade 415MPa.
3. M 25 grade of concrete to be used in foundation.
4. A lean concrete mix of 1:4:8 to be placed underneath R.C.C. footings of thickness 75mm.
5. Clear cover for Raft, Column pedestal and column are 75, 50 & 40 mm respectively.
6. Level and thickness of raft slab to be kept as per foundation details.
COLUMN FOOTING (COMBINED)
COLUMN
Column is referred to the vertical compression member of the structure. Columns also resist lateral loads due to wind and earth quakes. It consists of longitudinal reinforcement and horizontal ties in order to confine longitudinal bars.
SPECIFICATIONS OF COLUMNS
1. All the steel to be used should be of grade 415MPa.
2.Grade of concrete is given in table below –
FOUDATION TO 1st BASE. F. LVL.

3. The clear cover to all columns will be of 40mm.
4. The spacing between the horizontal ties is provided according to zone method.
ZONE A (h/6 from top and bottom)
10mm ø bars @ 85 mm c/c
ZONE B (between two A zones)
8mm ø bars @ 125 mm c/c
5.If a bar is missed or a new bar to be added at any floor level, must be done rebaring
PROCEDURE:
1. The projections from footing are extended by lap splices, using guidelines of lap splices from CODE IS 456:2000.
2. Horizontal ties are tied as per general notes.
3. Cover blocks are tied to bars for providing clear cover.
4..Shuttering of the column is done in accordance with layout of column and checked for its alignment.
5.Concrete is casted and compaction is done simultaneously.
TWO DIFFERENT STAGES OF COLUMN
BEAM
Abeamis a horizontalstructural element that is capable of withstandingloadprimarily by resistingbending. The bending force induced into the material of the beam as a result of the external loads, own weight,spanand external reactions to these loads is called abending moment.
SPECIFICATION OF BEAMS
1. Concrete of grade M 25 to be used for casting of beams.
2. The clear cover of 25mm to be provided.
3. All R/F. must be of grade 500MPa.
4. All primary beams shall be placed centrally placed at column centers.
5. All the secondary beams shall be placed centrally between primary beams.
PROCEDURE:
1. Staging is done for next floor level from foundation level.
2. Beams are framed between the columns as per framing plan of the floor level.
3. Beams are provided with cover blocks are made down in the formwork.
4. The slab reinforcement is tied both ways and projections are made for further extension of floor system.
5. Slab and beams are casted and compacted monolithically

SLAB
Slab along with beams make the floor system of the building. Slabs may one way or two way depending on their dimensions. It takes loads by bending alike beams.
SPECIFICATIONS FOR SLAB
1. Grade of concrete = M 25.
2. Grade of steel = 500 MPa.
3. Thickness of normal slab = 140mm.
4. Thickness of sunken slab = 300mm.
5. Clear cover to bars = 20mm.
6. Provided 2- 12mm bars underneath slab where there is no beam underneath wall.
7. Provided distribution reinforcement 8mm @ 250 c/c where ever required.
RETAINING WALL
Aretaining wallis a structure designed and constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds theangle of reposeof the soil. Retaining wallsare built in order to hold back earth which would otherwise move downwards. Their purpose is to stabilize slopes and provide useful areas at different elevations, e.g. terraces for agriculture, buildings, roads and railways.
The type of retaining wall is cantilever on the site having thickness of 450mm at bottom and tapers to 300mm at normal ground level. The grade of concrete used in retaining wall is M 25.
RETAINING WALL
