PREFACE

Practical training is one of the best ways to learn actually what youare studying theoretically. It provides us an opportunity to gain

knowledge about how actually a work or a task is started and

completed, also with the bonus of experience that one gets through

it and clears the concept in our minds.

I, Sandeep kumar, student of B.tech Civil Engineering, G.N.I.TCollege went through a five week summer practical training.

Exploring about the aspects of Civil Engineering construction in my

project and relating them to my previous knowledge made me

understand the real importance it has in my area of learning.

This is a report on the construction project ofKasturba BalikaVidyalayas Girls Hostel located in Ishwar Nagar, New Delhi.

Located adjacent to the Okhla Railway Station, it is spread in ground

area of about 11635 sqm. With all the important and basic facilities

and infrastructure, training under this project has aroused my

interest much more and has brought me confidence towards the

various aspects that Civil Engineering holds.

ACKNOWLEDGEMENT

Firstly, I would like to thanks my training incharge/staff for their

support. They have been a great source of information that has led

to this successful completion of the report. His vast knowledge

regarding core areas of civil has helped finalising my report. I would

also like to give full credit to the Irrigation & Flood Control

Department, New Delhi for allowing me to train under theirguidance. My heartly thanks also goes to Head of the Civil

Engineering Department, G.N.I.T College for giving me the privilage

to undergo this rigorous practical training outside the college.

The role of co-workers was also important to me as they gave me

the practical aspect of every single detail regarding the materials

they used in the construction of the building and the tasks which

were self performed by them. Without the assistance of all above

factors it would not have been possible for me to prepare the

report that is enriched with the information which i was blessed

during my summer training.

FIRST/SECOND FLOOR ROOFING DETAILS

The beams that are used to support the roof slabs of the first and

the second floor are respectively same in their cross section, length

and reinforcement, which means the first floor is similar that of the

second floor due to the similarity in the beams used for support.

SUMMARY

Kasturba Balika VidyalayaGirls Hostel, Ishwar Nagar, New Delhi is

the construction that is undertaken by Krishna Construction

Company with the consultancy of Designers Guild. Costing

approximately Rs 4.14 crores, the project was started on 1 April,2011, it provides accommodation to about 260 girl students of the

said school. Expected to completed by 30 September, 2012, it is a

project of 18 months duration. When i joined the project I saw the

construction at the reinforcement stage of the building and

observed other important parts of the construction such as brick

wall making, plastering, curing and also concreting. Some otherfinishing works that I learned about were tiles placing and floor

making.

The duration of my training was five weeks in which I learnt almost

all the things as I could vision all this which was due to the

accelerating pace of work and great experience that my trainingincharge and his co workers had. They had helped me understand

and learn about the various tasks, either related to construction or

estimating the cost of a particular item used in the construction. I

also have profit myself with some of the modern techniques that

were used to build major components of the hostel building.

Equipped with almost every facility required for a hostel and having

an ideal infrastructure, this project helped me learn the practical

7/30/2019 My Report (1)

16/18

aspects of what I learn in my institution, perhaps much more than

that.

This summer training helped me clear my vision towards Civil

Engineering as I learned many things that the textbooks

might have been insufficient for. After going through this practical

training I have no doubt that I will be able to see and learn new

things in a broad manner which will surely help me more in my

future Civil Engineering career.
