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 Tehsil Complex. This project is undergoing at Dharmkot ( Moga )
My due thanks also goes to the J.E Bharat kumar & Raman kumar & S.D.O Sodhi Ram for employing me as a training engineer and helping me to orient myself in the company for six months.
INTRODUCTION
ABOUT THE COMPANY PWD (B&R) DEPARTMENT Public Works Department (Buildings and Roads)is a premier agency of the State Government, up gradation and maintenance of roads, buildings and bridges in the State. The department also acts as the technical advisor to the State Government in all aspects of construction activity. From its inception in 1854,Public Works Department (Buildings and Roads)has been endeavoring to provide technical lead to other departments of the State Government by introducing latest construction techniques and materials, so as to achieve higher standards.
MY SIX MONTH TRAINING
THE BEGINNING:
My six month training was at P.W.D ( B.R ) at Dharmkot. 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 Dharmkot ( Moga ). The cost of the project is estimated to be around 33 crores . The proposed structure consists of a 4 storey building. (1 Basements) .Total number of buildings 2 . The site covers the area of 3,600 sq m. Total build up area is 2,320sq m .Height of the Super structure is 21meter ( 69 feet). . The structure is designed as earthquake resistant structure.
MACHINERY AND MANPOWER REQUIREMENT:
The manpower required during the construction period is around 150 persons per day. The Machinery used for construction works includes Concrete pumps, Mechanical compactors, Welding machines and Cutting machines etc. The machinery used temporarily at site was JCB, Trucks for transfer of material, Poclains, Generator, Tractor, Tipper, Welding equipment etc. Truck Mixers provide ready Mix Concrete to the site whenever it required
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 –

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
TYPICAL COLUMN SCHEDULE PLAN
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
DEEP BEAM
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.
