It is always a pleasure to remind the fine people in the Engineering program for their
sincere guidance I received to uphold my practical as well as theoretical skills in
engineering.
Firstly I would like to thank MR MD RAFIQUE KHWAJA (Director of
JIT) for meticulously planning academic curriculum in such a way that students are not
only academically sound but also industry ready by including such industrial training
patterns.
I express my immense pleasure and deep sense of gratitude to
MR. RAVI RAWAT (HOD CIVIL) for his guidness and others with me and also helped me
in completion of task.
Finally, I would also like to thanks MR Subrata Kundu (Site- In charge)for giving me

12.  Formwork
• Purpose:
Shuttering or formwork is the temporary arrangement by
wood/steel/ply to hold concrete in required shape and size
up to certain period for gaining adequate strength of the
concrete. Shuttering mainly costs 25-40% of the total cost of
the project. The Shuttering and Formwork is often similarly
used but there is a little difference in it in terms of materials
to be used. In shuttering generally plywood is used by in the
case of Formwork heavier sections like battens, Waller are
used.

13. Material Used:
 Steel plate and channel
 Battens (75mm X 100mm and 50mm X 75mm)
 Plywood of different thickness(Generally Film Face Ply of 2440mmX1220 mm
cross sections are available)

ground
 Safety nets are to be provided at levels where upper floors are engaged for
work to safeguard any material falling from height and hence protects the worker
working at ground.

33.  Quality control at site:
1. Quality Testing of Materials: The materials is mainly cement, fine aggregate, coarse
aggregate, water, admixtures, concrete and reinforcement bars. These materials are tested in
the quality control laboratory by following their test specifications according to their respective
IS Codes.
2. Quality Assurance: The test results of respective materials are obtained and checked whether
they lie within their acceptance limits specified codes. Then they are assured.

38.  SITE EXECUTION
 Execution is the discipline of planning, organizing, motivating, and
controlling resources to achieve specific goals at construction site as
per the scheduled planning. A project is a temporary endeavour
with a defined beginning and end
Requirements:
 Excavator
 Rollers for Soil Compaction if any (Smooth Wheeled or
Pneumatic or Sheep-foot)
 Shovel, Spade & Bucket,
 Auto Level or Total Station if available for knowing RL,
 Measuring Staff
 Measuring Tape

39.  SAFETY
 Safety Personal Protective Equipments( PPE ):
 In a particular site if personal safety is maintained by every personnel
then the total accident in the site can be controlled. It is just acts like
a pyramid, personal safety is in the base level so if it is controlled
then other accidents can be controlled simultaneously.

40. Sl No. Description Picture

Safety Helmets are used to protect
the head from falling materials in
construction site.
2
Safety Shoes which give us
protection on site, it has a steel plate to
its tow and protect our feet up to an
extent when a material sudden fails to
our feet. It is a very important
equipment in PPE.

Safety belt & Full body
Harness is very useful in
construction work, it used by labor
when working at heights to reduce
risk of falling particularly when they
are in formwork placing or plastering
of exterior parts.
etc

41. Safety controlling at site
Followings are some of the many precautionary/safety measures that are to be taken at a
construction site –
 Water spray on fly ash in order to prevent dust.
 Saline water is to be provided to workmen during summer to avoid heat related
illness. Proper rest is taken at intervals.
 Personal Protective Equipment (PPE) is provided and worn by construction workers at
site. PPE includes hard hats/helmets, Safety Shoes, Goggles, Masks, Gloves, etc.
 Medical and First Aid facilities is there.
 When working at heights, workers should wear double lanyard full body harness being
anchored. Safety helmets, fall arrester, etc. are used.
 Earth Leakage Circuit Breaker (ELCB) and Residual Current Circuit Breaker (RCCB) are
used in electric installations to avoid electric shock.
 Check for connection and body earthing of machineries.
 Transporting Vehicles must not exceed the speed limits (usually 15 Km/h max) to avoid
accidents by vehicles. For the same reason, use of mobile phones at site is minimized.
 Employees are to remain at a safe distance from all equipment while it is operational.
 Inspection of the equipment is done before every use.
 Checking Fire Extinguishers.
 Hygienic condition of labor hutment.
 Checking drinking water test report.
 Safety training program is in practice.
 Safety Award for safety motivation is conducted.
 Daily safety observation and correction is done.

43.  Materials Management
 Profit Centre
 With the process of liberalization and opening up of global economy, there
has been a drastic change in the business environment, resulting in
organization exposed to intense competition in the market place, Indian
organizations have been working out various strategies to face the above
challenges and to cut down operational cost to remain competitive.
Progressive management have since recognized that materials
management can provide opportunities to reduce operating cost and can
be treated as a profit center.
 On an average, half the sales income is spent on materials. Suppose a firm
is spending 50% of its volume on materials and the profits are 10% of sales
volume. A 2% reduction in materials cost will boost the profits to 11% of
sales or the profits will be increased by 10%. To achieve the same increase
in profit through sales efforts, a 10% increase in sales volume will be
necessary. In other words, compared to sales volume, material cost has
five times the average on profits. Organizations earn or loose large sums
depending on how effective are their material management

44.  CONCLUSION
 The training programme helped in gathering the practical work procedure
alongside with furnishing the theoretical knowledge learnt till date. The
programme was scheduled and comprised of five different sections – Safety,
Planning, Billing, Quality Control and Site Execution. The importance of safe
working, adopting safety measures and preparedness for any unknown sudden
accidents at site were explained in the safety department. The work of the
planning engineer and the procedure of a proper planning and scheduling of the
construction work, these knowledge were shared in the planning department.
Billing department enriched us with the financial knowledge, quantification of any
work and their collaboration with the planning department. The purpose of the
quality control department, continuous checking of the materials at the site and
preparation of design mixes were taught. Finally all the gathered knowledge were
practically viewed during site execution of different blocks. Shuttering procedure,
different construction works, machineries and all the safety measures adopted
were clearly explained. Apart from technical knowledge we were grateful enough
for the engineers who shared their work experience with us. There are a lot of
things which cannot be learnt from any books or institution but an exposure to
such a construction site can only provide. Such construction site related essential
terms & knowledge of work will help us throughout our work life
