3.  Our project is successful due to the effort of those people who have
given their valuable time and advice.We sincerely appreciate the
inspiration,support and guidance of all those people .
 We,the student of “NARULA INSTITUTE OF TECHNOLOGY“ are
extremely thankful to “GAMMON INDIA LTD“ for giving us the
opportunity to practically experience their metro project at site.
 At this juncture we feel deeply honour in expressing our sincere
thanks to Er.Kousik Rakshit sir,Er.M.Haque sir,Er.Bittu Bawali
sir,Er.Arghya Das sir,Er.Partha Chakraborty sir,Er.Abhinav Chatterjee
sir for making the resources available at right time and providing
valuable insights leading to the successful completion of our project.
 I would also like to thank all the faculty member of NARULA
INSTITUTE OF TECHNOLOGY for their advice and guidance without
which this project would not been possible.

4. SUBJECT:PARAPET CASTING
(SITE:NEAR TECHNOPOLIS)
 PARAPET :
It is a structural member which is fix over the segment.
As a technical view, parapet basically used for walk way
for maintenance and surveillance and also used for
cable transmission. Parapet also gives beautification of
the structure.
 MATERIAL USED IN PARAPET MAKING :
Two different Dias of rods (8mm & 10mm) are
used for parapet reinforcement and M40 grade of
concrete is used for this structure.

5. Reinforcement of Parapet-
 Steel of SAIL and RVNL is used as reinforcement,
 PROTMAX inhibitor solution is used as an
anticorrosive treatment with cement slurry which is
applied on the rod.
Bed-
 Bed is that on which the parts of reinforcement are
joined together by diamond binding. Bed is
fabricated by M.S Plate, Rubber Pad & G.I member.

6. Concreting procedure -
Parapets generally concreted on the bed, with a concrete
of particular w/c ratio required. In some case vibrator is
used at the time of concreting to ensure zero void inside.
Admixture-
 In case of parapet casting STRUCTRU 201
admixture is used for increasing the workability.

7. Part of Parapet Structure –
Parapet structure mainly consisting of three
parts-(generally)
 Walk Way (0.179 sq.m)
 Web(0.188 sq.m)
 Parapet Bottom(0.141 sq.m)

8. SUBJECT:SEGMENT
CASTING
(SITE:NEAR MANI SQ)
 BASIC STEPS OF
SEGMENT CASTING:
1)ROD BENDING
(according to drawing)
2)Rod binding
3)Placing of rod cage
into bed.
4)Shuttering.
5)Concreting and
Curing.

10. STEPS OF CONCRETE MIX DESIGN :
According to IS 10262:2009
STEP 1 : Target Strength for Mix Proportioning
STEP2 : Selection of Water-Cement Ratio
STEP3 : Selection of Water Content
SETP4 : Calculation of Cementitious Material Content
STEP5 : Estimation of Coarse Aggregate Proportion
STEP6 : Combination of Different Coarse
Aggregate
Fractions
STEP7 : Estimation of Fine Aggregate Proportion
STEP8 : TRIAL MIXES

16.  We have learnt so many things about
kolkata metro project from the respected
site engineers.
 We want to say thanks to the engineers to
spend their valuable time with us.
 They energized us for this work.
