BRIEF INTRODUCTION OF PROJECT
Western Dedicated Freight Corridor Project
Logistic management is going through a sea-change with India’s largest and the first-of-its-
kind project in the rail sector to augment the rail infrastructure to increase share in rail freight
market by offering customers, a guaranteed, faster transit at economic tariff. Dedicated
Freight Corridor Corporation of India Limited (DFCCIL) - a Special Purpose Vehicle set-up
under the administrative control of Ministry of Railways is undertaking planning and
development, mobilization of financial resources and construction, maintenance and
operation of Dedicated Freight Corridors connecting different states of the country. In the
first phase, DFCCIL will be constructing two corridors - the Western Dedicated Freight
Corridor (WDFC) and Eastern Dedicated Freight Corridor (EDFC) - spanning a total length
of about 3322 route km. The DFC project on the Western and Eastern routes is one of the
most ambitious projects that Indian Railways has ever taken up and once completed, would
meet the transport requirements of the two busy trunk routes for the next 15 to 20 years.
The WDFC (1483 km) will be from Jawaharlal Nehru Port (JNPT) in Mumbai to
Tughlakabad and Dadri near New Delhi and would cater largely to the container transport
requirements between the existing and emerging ports in Maharashtra and Gujarat and passes
through the states of Haryana and Rajasthan
Sojitz - L&T Consortium (WDFC: Rewari - Iqbalgarh Section)
A part of the Western Dedicated Freight Corridor has been secured by a consortium of Sojitz
Corp., Japan and Larsen and Toubro Limited, India. Sojitz Corporation, a general trading
company conducts its operations in about 50 countries through 505 consolidated subsidiaries
and affiliated companies all over the world. Sojitz’ business activities are wide-ranging
encompassing machinery, aerospace, energy and mineral resources, chemicals and plastics,
etc.
L&T, India’s largest engineering, technology, construction and manufacturing organization
has established itself as a unique service provider delivering turnkey solutions for all types of
railway projects. The Railway Strategic Business Group of L&T has taken the lead in rail
construction by introducing pioneering techniques, resulting in execution of projects with
innovation, quality and speed. The combination of the distinct strengths of these two
companies will help create one of the fi nest rail infrastructures in the country.
The EPC order involves construction of 626 km of a double track corridor from Rewari in
Haryana to Iqbalgarh in Gujarat, via Rajasthan, spanning three states. This is the country’s
largest project awarded so far in the rail sector and the first-of-its-kind in India.
Comprehensive solutions from industry leaders
The scope of work includes construction of 1388 track km (excluding turnouts) of railway
line, 1342 bridges, and 20 stations along with supply of all associated equipment. This project
will be executed using mechanized means of track linking and employing the latest
technology and advanced construction methodologies in railway construction
Design - The fountainhead of innovation
Dedicated Freight Corridors are proposed to adopt world-class and state-of-the-art
technology. Significant improvements are being incorporated in the existing carrying

9
capacity by modifying basic design features. The permanent way will be constructed with
significantly
higher design features that will enable it to withstand heavier loads at higher speeds.
Simultaneously, in order to optimise productive use of the right of way, dimension of the
rolling stock is proposed to be enlarged. Both these improvements will allow longer and
heavier trains to ply on the Dedicated Freight Corridors. The track will be designed for 25 t
axle load to run double stack containers dedicated for freight and 32.5 t axle load for bridges
and embankments.
The Sojitz - L&T consortium will offer its expertise and extend its experience right from
inception reports to technical design, alignment design and track design apart from validation
of survey data, right of way and final location survey. With the geo-technical engineering
expertise gained over the years, the consortium will monitor and control earthworks right
from sub-soil, subgrade to ballast and sleepers and offer strong and supreme quality of rail
infrastructure dedicated for freight. Since the project involves significant major bridges,
various parameters have been taken into consideration for design of special launching and
erection techniques.

10
Project Management - Charting the way to quality and speed
The Sojitz - L&T Consortium envisions using the latest technology in rail construction. Key
components sourced through specialist international vendors / subcontractors include:
• Head Hardened Rails from Japan
• Complete Engineering Procurement and Construction by Sojitz - L&T Consortium
• New Track Construction Machine from Harsco Rail, USA
• Locomotives from India
• Permanent way components from approved RDSO (Indian) Agencies
A comprehensive strategy for speedy construction has been evolved considering every facet
of project management. Key establishments envisaged for design, construction and
commissioning include setting-up of design office in New Delhi, Project office in Jaipur,
Strategic section offices in Ajmer, Shri Madhopur and Marwar, Offices at 10 stations,18
Labour camps at Base depots, Casting yard and Stations.
Construction Methodology (Smarter ideas, faster implementation)
The DFC project will introduce numerous world-class technologies right from planning,
design, construction to the operation of the line. The laying of sleepers and tracks will be
done using state-of-the-art mechanised track laying equipment. Specialised group of track
machines will be deployed to carry out ballast tamping, ballast regulating and track
stabilisation. Even the field joints will be brought to bare minimum due to the deployment of
high capacity, robotic mobile flash butt welding machines
Advantages of mechanized track linking
• Well-regulated supply of sleepers and rails directly fed from the depot
• Higher output per hour can be achieved
• Dependency on labour is considerably reduced
• Supreme quality of execution

11
Project Infrastructure
project Benefits for the Nation, Trade & Commerce and to the people of
India
• The Dedicated Freight Corridor (DFC) will contribute to India’s economic
development by freight transportation which is expected to undergo rapid growth in
the future.
• This project enables a segregated electrified line for freight, parallel to the existing
railway line. This indirectly allows the passenger trains to move faster in the existing
lines.
• This line will allow double-stack with a height of 7.1 m through wider tracks of 3.6 m
that allow longer train lengths of 1500 m that can travel at a faster rate of 100 kmph.
For the industry this means, reduced unit cost of transportation as DFC provides rail
infrastructure to carry higher throughput per train.
• The route will also have lesser stations that fall only once every 30 - 40 km. The
entire corridor is expected to offer more axle load and an increased overall freight

12
train load by 3.5 times the current capacity. Again for the industry, this means a
guaranteed, faster transit at an economic tariff.
• Apart from improving the overall transport efficiency of the national network, DFC
will help accelerate the nation-wide economic development as well as improve the
environment. Transportation of goods through DFC will consume less energy when
compared to truck mode and the gas emission is completely avoided along the DFC
alignment.
• With the increase of trade and industrial development along the DFC, there will be an
increase in employment opportunities of the region.
• DFC will also improve and expand the market for agricultural produce, forestry and
fisheries of the regions as the speedy and improved transportation mode will help
shrink distances connecting the supply and demand points.

SOIL PENTROMETER
PROCEDURE
1. About 150 gm. of air dried soil from thoroughly mixed portion of material passing 425
microns IS sieve is obtained.
2. Distilled water is mixed to the soil thus obtained in a mixing disc to form a uniform
paste.
3. Then the wet soil paste is transferred to the cylindrical cup of cone penetrometer
apparatus, ensuring that no air is trapped in this process.
4. Finally, the wet soil is levelled up to the top of the cup and placed on the base of the
cone penetrometer apparatus.
5. The penetrometer is so adjusted that the cone point just touches the surface of the soil
paste in the cup and the initial ready is to be taken.
6. The vertical clamp is then released allowing the cone to penetrate into soil paste under
its own weight for 5 seconds. After 5 seconds the penetration of the cone is noted to the
nearest millimetre.
7. The test is repeated at least to have four sets of values of penetration in the range of 14 to
28 mm.

TESTS ON FRESH CONCRETE
SLUMP
AIM
To determine the workability of fresh concrete by slump test as per IS: 1199 - 1959.
APPARATUS
i) Slump cone
ii) Tamping rod
PROCEDURE
1. The internal surface of the mould is thoroughly cleaned and applied with a light coat
of oil.
2. The mould is placed on a smooth, horizontal, rigid and non- absorbent surface.
3. The mould is then filled in four layers with freshly mixed concrete, each
approximately to one-fourth of the height of the mould.
4. Each layer is tamped 25 times by the rounded end of the tamping rod (strokes are
distributed evenly over the cross- section).
5. After the top layer is rodded, the concrete is struck off the level with a trowel.
6. The mould is removed from the concrete immediately by raising it slowly in the
vertical direction.
7. The difference in level between the height of the mould and that of the highest point
of the subsided concrete is measured.
8. This difference in height in mm is the slump of the concrete.
The slump measured should be recorded in mm of subsidence of the specimen during the test.
Any slump specimen, which collapses or shears off laterally gives incorrect result and if this
occurs, the test should be repeated with another sample. If, in the repeat test also, the
specimen shears, the slump should be measured and the fact that the specimen sheared,
should be recorded.
MIX DESIGN
What is mix design?
Concrete is an extremely versatile building material because, it can be designed for strength
ranging from M10 (10Mpa) to M100 (100 Mpa) and workability ranging from 0 mm slump
to 150 mm slump. In all these cases the basic ingredients of concrete are the same, but it is
their relative proportioning that makes the difference.
Basic Ingredients of Concrete: -
• Cement – It is the basic binding material in concrete.

30
• Water – It hydrates cement and also makes concrete workable.
• Coarse Aggregate – It is the basic building component of concrete.
• Fine Aggregate – Along with cement paste it forms mortar grout and fills the voids
• in the coarse aggregates.
• Admixtures – They enhance certain properties of concrete e.g. gain of strength,
workability, setting properties, imperviousness etc. Concrete needs to be designed for
certain properties in the plastic stage as well as in the hardened stage.
Properties desired from concrete in plastic stage: -
Workability Cohesiveness Initial set retardation
Properties desired from concrete in hardened stage: -
Strength Imperviousness Durability
Concrete mix design is the method of correct proportioning of ingredients of concrete, in
order to optimise the above properties of concrete as per site requirements. In other words,
we determine the relative proportions of ingredients of concrete to achieve desired strength &
workability in a most economical way.

About open foundation (Raft Foundation)
Foundations provide support for structures, transferring their load to layers of soil or rock that
have sufficient bearing capacity and suitable settlement characteristics. Very
broadly, foundations can be categorised as shallow foundations or deep foundations.
Shallow foundations are typically used where the loads imposed by a structure are low
relative to the bearing capacity of the surface soils. Deep foundations are necessary where the
bearing capacity of the surface soils is not adequate to support the loads imposed by
a structure and so those loads need to be transferred to deeper layers with higher bearing
capacity.

2. SPT (standard penetration test) of soil
The standard penetration test (SPT) is an in-situ dynamic penetration test designed to provide
information on the geotechnical engineering properties of soil. The test procedure is
described in ISO 22476-3
Purpose
The main purpose of the test is to provide an indication of the relative density
of granular deposits, such as sands and gravels from which it is virtually impossible to obtain
undisturbed samples
PROCEDURE
1. Identify the location of testing in the field
2. Erect the tripod such that the top of the tripod head is centrally located over the testing
spot.
3. Slip the 63.6 kg weight on to the guide pipe assembly and connect the guide pipe
assembly to the other end of the A-drill rod.
4. A person should hold the guide pipe assembly split spoon sampler to be vertical with the
falling weight lowered to the bottom of the guide assembly.
5. Now place a straight edge across the bore touching the A-drill rod. Mark the straight
edge level all-round the A-drill rod with the help of a chalk or any other marker.
6. Count the number of blows required for the first 15 cm, second 15 cm and the third 15
cm mark to cross down the straight edge.
7. The penetration of the first 15 cm is considered as the seating drive and the number of
blows required for this penetration is noted but not accounted in computing penetration
resistance value. The total number of blows required for the penetration of the split
spoon sampler by 2nd
and 3rd
15 cm is recorded as the penetration resistance or N-value.
8. After the completion of the split spoon sampler by 45 cm, pull out the whole assembly.
Detach the split sampler from A-drill rod and open it out.
9. Advance the bore hole by another 1 m or till a change of soil strata whichever is early.
10. The test is repeated with advancement of bore hole till the required depth of exploration
is reached or till a refusal condition is encountered. Refusal condition is said to exist if
the number of blows required for the last 30 cm of penetration is more than 100.
11. The test will be repeated in number of bore holes covering the site depending on the
building area, importance of the structure and the variation of the soil properties across
the site.

15. Binding material
MasterEmaco SBR 2 is a milky-white, Styrene-Butadiene co-polymer latex liquid, produced
from styrene and butadiene by high pressure emulsion polymerization with high dispersive
properties. When used with cement, concrete and plaster, it reduces the mixing time through
high dispersion of the polymer and improves waterproofing, new to old concrete/plaster
bonding and strength characteristics and reduces shrinkage and cracking of the mix.

KEY LEARNING
My first learning and most important stage for both project and mine was at QA/QC Lab.
At this platform I learned many test, listed below;
• Soil Test
• Cement test
• Aggregate test
Soil Test:
A). GSA Test (Grain Size Analysis)- IS-2720 Part 4
This test is most vital test for analysing grain size in soil. According to analysis we define
the soil comes under SQ1, SQ2 or SQ3 (SQ- Soil Quality). After defining the fineness of soil
we decide whether the soil fit for Embankment, Subgrade or for Blanket according to IS
code.
B). MDD Test (Maximum Dry Density) – IS-2720 Part 8
This test is performed to find the maximum dry density of soil for compaction and finding
the OMC (Optimum Moisture Contain). This test is basically performed to find the OMC
which we further be used for CBR Test. This test also defines the percentage of water should
be poured or mix in soil for best compaction.
C). CBR Test (California Bearing Ratio)- IS-2720 Part 16
After defining the OMC of the soil, the soil is further carried for finding the Load Bearing
Capacity of Soil. After finding the load bearing capacity of soil we define the soil whether to
be used for Embankment or for Subgrade. The load bearing capacity in percentage for;
 Not less than 5% for embankment.
 Not less than 8% for subgrade.
D). FSI Test (Free Swell Index)- IS-2720 Part 40
This test is performed for finding the swelling of soil in water with comparison to kerosene.
Swelling of soil should not be <10% in water with comparison to swelling in kerosene.
Cement Test
A) Consistency Test – IS-4031 Part 4
Performed to find the water quantity required for best compaction. With the help of Vicat
Apparatus.
B) Initial and Final setting of cement – IS-4031 Part 5
Learned how to find the initial and final setting of cement with the help of Vicat Apparatus.
 Initial Setting Time – 30 minutes
 Final Setting Time – 8 to 10 hours

54
C) Soundness of cement- IS-4031 Part 3
 Soundness means the expansion of cement under pressure and temperature.
 Le-Chatlier Apparatus is used for finding the soundness of cement.
 The expansion should not be greater than 10mm
D) Fineness of cement – IS-4031 Part 1
 It is performed to find the fineness of cement which should not be less than 90%.
Aggregate Test
A) AIV Test – IS-2386 Part 4
This test is performed to find the strength of aggregate when there is a sudden impact on
them.
Precast Yard
Pre Cast Yard gave me vast knowledge about different types of Pre Cast Structures, with
different shape & size, which impart in actual construction of different types of structures
such as – Foot Over Bridge, Box Culvert Bridge, and Abutments for Bridges, etc.
 Types of precast structures
 Casting of I-Girder
 Reinforcement of I-Girder
 Profiling in I-Girder
 Shuttering of Girder
 Concreting of Girder
 De-shuttering of Girder
 Curing of Girder
 Stressing in Girder
 Grouting in Girder
On site
A) FDD Test (Field Dry Density)- IS-2720 Part 28
This test is performed to cross check the MDD of soil, which on earthwork named as FDD.
 FDD test with Sand Replacement Method
 Apparatus used Rapid Moisture Meter
 The FDD as compared with MDD in lab should be;
 97% for Embankment soil
 98% for subgrade soil
 100% for Blanket.
Major bridge 431
 We learned about types of foundation and also worked on the raft foundation
 We learned the propose of Standard penetration test, the test is used to determine the
load bearing capacity of the strata.
 We also learned the excavation process for foundation

55
 We also learned the level shifting from the BM to foundation level and PCC level
 We also learned how to place bars of foundation and pier according to BBS
 We learned the method of shuttering, concrete, de-shuttering and curing
Major bridge 434
Learned how to perform Lateral Pile Load Test, for Pile Foundation, to check the Horizontal
displacement.
Other than the above learning
 Waste Utilisation and Cost Minimisation
 Whenever do we do concreting work it is certain some quantity of concrete comes
extra. Which might be waste and tendency to make its alternative arrangement for
utilisation on place of fresh concrete like back filling, some precast, drain work,
sitting places and for some arrangement for public places.
 Drainage Management
 Labour Management
 Land slide prevention during excavation by pouring mortar on soil.
Development of Management Skills:
On Bridge No. 431, it is highly populated area as it is located on Railway Station of Beawar,
so how to manage public with all the vehicles, so safety criteria should be maintained
properly. Site Engineer should know how to manage Supervisors, Labours etc. During
placing of Shutters on Piers it should be done properly and carefully. While excavation be
careful about Pipe lines and underground wires. During Shuttering and De-shuttering of Pier
be careful about Electricity poles and high tension cables around the area.

56
CONCLUSION
It was a wonderful learning experience at Sojitz - L&T Consortium ‟s site of
project for two months in Beawar(Ajmer). I gained a lot of insight regarding
almost every aspect of site. I was given exposure in almost all the
departments at the site. The friendly welcome from all the employees is
appreciating, sharing their experience and giving their peace of wisdom
which they have gained in long journey of work. I am very much thankful
for the wonderful accommodation facility from L&T. I hope this experience
will surely help me in my future and also in shaping my career.
