A Completion estimate is prepared in super
session of construction estimate. Following particulars are included in the
Completion estimates.
i. Amount of sanctioned
estimate.
ii. Actual expenditure on
all works up to the date of construction estimate.
iii. Commitments on that
date.
iv. Anticipated further
outlay.
v. Total estimated cost
and
vi. Difference between
the sanctioned estimate and the estimated cost.
It is prepared on form No E 713.
(
d ) On account Bill & Final Bill :-
On
account Bill :-
On account Bill or running bill prepared
on Form No. E 1337 is indicated for use in contract works only and not supplies
. On account payments before the
completion of a work should be made through this form.
Final
Bill :-
The final bill prepared on form No. E 1338 should be used for making final payments . i.e. On
closing running accounts for works . Normally only one final bill should be
prepared against an agreement or work order . But in cases where groups of
annual repair works are included in one agreement or work order there is no
objection to more than one final bill being prepared on the completion of each
group or certain groups.
( e ) M.A.S. Accounts –
This stands for material at site
account. This is a suspense head of account that is maintained to watch actual
consumption of materials obtained for specific work such materials stores are
requisitioned separately by the executive officer and consigned to the site of
work. The monitory value of materials consumed is debited to the work concerned
through works Register. The balance under this suspense represents materials on
hand yet to be consumed.
Q.2.- Describe the various budget stages for
review / modification of budget grants, what is the time schedule for the
divisions to submit their requirements to the Head quarters at each stage?
Ans.- Following are the Budgetary reviews under taken on
Railway during the course of a financial year –
i. August Review – This is one of the Budgetary reviewed stages.
This is conducted in the month of August every year by all the spending units /
executives to see that any modification are necessary in the allotments placed
at the disposal at the beginning of the year.
ii. The second budgetary
review is carried out at the time of submission of revised and Budget estimate.
The revised estimates for the current year are shown on the basis of conclusions
derived after this examination in respect of revenue expenditure.
iii. Modification Statements – Railway Administration are required
to review the budgetary position even after the receipts of revised allotment
and advise the position to Railway Board in regard to additional allotment
required or surrenders to be made during the current year under each head of
grant or appropriation. This is done through the submission of modification
statements. First modification statement is sent to Board by 1st
February and final modification statement is sent by 21 st February.
Q.3.- Distinguish between any three of the following -
a) Earnest money and security deposit.
b) General Conditions of Contract and Special
Conditions of contract.
c) Revised Estimate and Supplementary Estimate.
d) Final modification Material Modification.
e) Reappropriation of Funds and Misappropriation
of Funds.
Ans.-
( a ) Earnest
money and Security Deposit –
Earnest
money –
The Tenderer shall be required to deposit
Earnest money with the tender for the due performance with the stipulation to
keep the offer open till such date as specified in the tender. Earnest money
should be either in cash, deposit receipts, pay orders, demand draft.
The earnest money shall be 2% of estimated
tender value. The earnest money shall be rounded to the nearest Rs. 10/- .
Earnest money shall be applicable for all modes of tendering
Security
Deposit – A
Security deposit is taken for the satisfaction of and efficient execution of
the work within the agreed time from contractors. Such Security deposit may
also be percentage deduction from on accounts bills of contractors called as
retention Money usually 10% of the gross amount of bill. The scale of Security
Deposit is as under –
- Contracts
up to one lack in value 10% of the value of contract.
- Next
one lack in value 7½% of the value
of contract.
- For
3rd one lack and
above in value 5% of the value of contract. Subject to maximum of 10 lacks.
The amount over and above 3 lacks to be
recovered from the progressive bills of the contractor at the rate of 10% till
it reaches the required value.
( b ) General
Conditions of Contract and Special Conditions of Contract -
General
Conditions of Contract – Operation of a contract is based upon the various
stipulation contained in the General condition of contract. This is in the form
of a booklet and forms as essential part of the tender documents and ultimately
of the contract documents. It is essential that every body dealing with
contract should be aware of the contracts of this booklet. These general
conditions are normally applicable to all contracts and can be superseded when
special conditions are specially formed and stipulated in the tender documents
/ agreement.
Special
Conditions of Contract – These are the conditions which are not covered in the
general conditions of the contract.
The special conditions of contract arise due
to the site conditions and the nature of work to be carried out. These
conditions are framed by the Executive and the contractor is bound to fulfill
the conditions during the execution of specific works and all out general
application.
( c
) Revised Estimate and Supplementary Estimate.-
Revised
estimates –
Revision of estimates is some times necessary
if there is rise in rates of materials, cost of labour, alteration in design
etc. If the rise in the cost of work is likely to be more than 10% or Rs.
10,000/- a revised estimates is required to be made. Revised estimates should
be prepared in the same degree of detail as the original estimates. The reasons
for exceed should clearly explained.
Supplementary
estimates –
If it is necessary to do any additional work,
after an estimate is sanctioned or if any substantial changes are required to
be made Supplementary estimates are made in a similar manner as the detailed
estimate. The details of items should include only the extra amount of work
needed to be executed.
( d
) Final modification Material Modification. -
Final
Modification :-
Railway administration are required to review
the budgetary position even after the receipts of revised allotment and advise
the position to Railway Board in regard to additional allotment required or
surrenders to be made during the current year under each head of grant of
appropriation . This is done through the submission of modification statements.
The third review is conducted in the month of
February every year and is known as final modification. Actual expenditure
during first Nine months and approximate expenditure for the Tenth month is
reviewed and compared with: -
Budget grant/ revised grant (if received)
Budget proportion.
Actual expenditure during the last financial
year.
Actual expenditure during corresponding
period of the last financial year.
Material
modification :-
No material modification in a work or scheme
as sanctioned should be permitted or under taken with out the prior approval of
the authority who sanctioned the estimate . In the case of estimates sanctioned
by the Railway Board or higher authority instances of will be considered to be
a material modifications of a sanctioned project or work are given in below –
The following may be taken as material
modifications on the lines under construction and open line works estimated to
cost rupees one crore and over .
Any change in the alignment likely to affect
the facilities offered to the public in the neighborhood or likely to increase
or decrease the length of the line by over one kilometer.
Introduction of any new station or omission
of any station.
Any alteration in the type or number of
engines or vehicles provided in an estimate for rolling stock.
A change in the layout of a yard affecting
the general method of working or increasing or deducting the number of trains
that can be dealt with.
i. Any departure from
the standards of construction as
accepted by the railway board in the Abstract estimate or use of any second new
material.
ii. The introduction or
omission of any work or facility involving a sum of Rs. 5 Laces and over.
iii. Any modification of a
sub work provided for in the estimate of a sanctioned work involving an
additional out lay on that sub work of more than Rs. 5 laces.
iv. The introduction of
any new sub work not provided for in the estimate of a sanctioned work
involving an out lay of more than Rs. 5 laces.
v. Any alteration in the
standards of inter locks.
( e
) Reappropriation of Funds and Misappropriation of Funds. -
Reappropriation -
The transfer of funds originally assigned for
expenditure on a specific object to supplement the funds sanctioned for another
object is called ‘’ Reappropriation’’.
Misappropriation
Of Fund -
Misappropriation Of Funds allotted for
specific works under capital or Revenue demand but the expenditure is incurred
for another work for which there is no competent authority sanction i.e.
expenditure is not voted by Parliament, voted by Parliament but not
Reappropriated by the competent authority. Misappropriation Of Fund is a major
irregularity in financial point of view and may invite accounts as well as
audit objections.
Q.4.- Write short notes on any Three of the following -
a) Trade Test.
b) Over Time.
c) Corporate Enterprise Group.
d) Payment Of Wages Act.
e) Minor Penalty.
Ans.-
( a ) Trade
Test -
With a view of perform the work in a trade an
artisan staff should have the skill required for the trade and for this Railway
workers classifications Tribunal in 1948 emphasized that the fairest and the
best means of classifying the artisans in skilled and semi skilled in each
trade should be through the trade test method.
The trade tests will be arranged by an
Assistant officer of the branch concerned. The results of Trade test should be supervised by an official not below
the rank of IOW in charge.
The trade test result with the
recommendations of the trade testing officer will be placed through the senior
scale office of the branch concerned officer of deputy’s rank who are competent
to approve of the trade test Assessments.
( b )
Over Time –
Under the HOER the earning of over time
depends on the extra amount of work performed between the rostered hours and statutory
limits or beyond the statutory limits on the basis of either daily or weekly or
two weekly periods as may be prescribed for different categories.
The staff has to work over time when it is
necessary due to accidents emergencies, clerical staff are not entitled for
over time.
Over time is paid at one and half times of
the wages per hour of duty if the employee has worked between the rostered
limit and statutory limit and twice the ordinary wages per hour of duty if the
employee has worked beyond the statutory limit.
( c ) Corporate
Enterprise
In order to have better and systematic
participation of labour in management for improvement in working of Railway
system and appropriate changes for improving efficiency and viability a
Corporate Enterprise Group was set up at central level in ministry of railways
in the year 1972.
This group consists of chairman members and
secretary of Railway Board on one hand and on the other hand three
representatives each of the NFIR and AIRF and one representative of the
officer’s federation.
The Board objectives of the corporate
Enterprise Group are to –
Evaluate functioning of the Railways and
exchange data ideas on ways and means for improving the efficiency and
viability of the enterprise.
Appraise the investment programme,
particularly in regard to housing and welfare service.
Identify areas and devise action-oriented
methods for maximizing organizational effectiveness the use of technology and
towards building up the image of the railways as a service organization.
Staff matters including those which come
within the purview of the PNM & JCM are not to be discussed by the
Corporate Enterprise Group.
( d

Q.6.- What are the various types of leave that an
AEN can possibly get ? What are their respective entitlement/ which of these
can be carried forward to the next year? What is the maximum limit to which the
same can be accumulated?
Ans.- Various types of leave that an
AXEN / ADEN
i. Earned Leave ( APL )
–
Thirty days Earned Leave is credited to one’s leave account every year 15 days
on 1st Jan. and 15 days on 1st July. Maximum leave that
can be accumulated at any time is 300 days. Encashment of un utilized leave up
to 300 days is permissible on retirement / death of an employee.
ii. Leave on Half Pay – It is earned at the
rate of 20 days for each calendar year . Leave on Half pay can be converted in
to full pay on medical grounds and also for approved course of study. The leave
converted is called Commuted Leave. In case of grant of Commuted Leave twice
the amount of such leave is debited against the half pay leave due. Half pay
leave credited in 10 days on 1st Jan and 10 days on 1st
July on every year. Encashment not permissible.
iii. Maternity Leave – It may be granted to
female Railway employees for a period of 135 days on full pay provided they do
not have more than one child. This is also admissible in case of abortion /
miscarriage to the extent of 45 days in the entire service.
iv. Paternity Leave – A male Railway
servant with less than two living children may be granted Paternity Leave for a
period of 15 days during the confinement of his wife.
v. Study Leave – Study Leave up to a
maximum period 24 months in the entire service may be granted to a Railway
servant for undergoing a special course consisting of higher studies or
specialized training in a professional or technical subject having a direct and
close connection with the sphere of his duties or being capable of widening his
mind and improving his ability as a railway servant.
vi. Casual Leave – casual leave is not
a recognized form of leave. It can not be combined with any other kind of leave. Holidays,
Sundays falling within the spell of casual leave do not count as casual leave.
The staff who are not permitted to enjoy all holidays are entitled to 11 days
casual leave. Casual leave if not availed during a calendar year will lapse.

patrolling.
j)
Gauge
conversion.
Ans.- ( a ) Under Reamed Piles –
Under Reamed Piles mainly used in shrinkable
soils ( black cotton soils ) to over come the effect of differential settlement
due to volumetric change in soil effected by seasonal variations. It can also
be used for sandy and clayey soils. These are three type –
i.Single
under reamed piles.
ii.Double
under reamed piles.
iii.Multiple under reamed piles.
The diameter of under reamed bulb is normally
2.5 times the pile diameter and spacing of bulb should not exceed 1.5 times of
the bulb. The minimum diameter of piles should be 20 cm. The top most bulb
should be at minimum depth of two times of the bulb diameter. Minimum spacing
of piles should be two times the bulb diameter.
( b ) CSM –
A new type continuous action 09-CSM tamping
machine has been introduced by M / S Plasser & Theurer. The actual work
units however which consist of tamping lifting and lining units are positioned
in a separate under frame and are moved in a work cycle from sleeper to
sleeper.
Two independent tamping units are provided,
one for each rail. These are attached to the machine frame by means of vertical
guiding columns. The tamping units are
fitted to the satellite Frame.
The tamping units may be for tamping one
sleeper or two sleepers or three sleepers at a time depending upon type/model
of tamping machine. 16 tamping tools are provided for tamping each sleeper. The
tools are arranged in pairs and each sleeper is tamped by 8 such pairs, on both
side of each rail. The units are held by horizontal guiding column in order to
slide sideways, which allows their automatic centering over the rails in curves.
The tools are vibrated by piston rods pivoted
on eccentric shaft driven by hydraulic motors.
( c ) Track recording
–
Track
recording consists of objective method of assessment of the quality of track
with the help of sophisticated equipments. A continuous record of various track
parameters is made with the help of the track recording devices from which an
assessment can be made about the running quality of track. Using any of the
following equipments- normally does track recording
i.
Hallade
Track Recorder.
ii.
Amsler
Track Recording Car.
iii.
Oscillograph
Car.
iv.
Portable
Accelerometer.
v.
Track
Recording cum Research Car.
vi.
Track Recording Trolley.
( d ) Railway
Affecting Tanks –
Where as per current practice the Public
Works or Revenue Department forwards to the Divisional Engineer every year,
their inspection reports on the condition of these tanks which are classified
as Railway affecting, action should be taken as follows:–
(a) The Divisional Engineer should peruse the
reports carefully and mark those tanks which he considers are not in
satisfactory state of repair. He should then forward the reports to the
Assistant Engineer with instructions that the tanks so marked should be
inspected and reported on.
(b) The Assistant Engineer should inspect those
tanks and report to the Divisional Engineer details of the action being taken
by the Public Works or Revenue Department. The Divisional Engineer should
prevail on the authorities concerned to carry out all necessary repairs before
the ensuing monsoon.
(c) Copies of the inspection notes of
‘Railway Affecting’ tanks as received from the Public Works or Revenue
Department with particulars of date of inspection and notes of action taken or
proposed by him should be included in the Register of Railway
Affecting
Works maintained by the Assistant Engineer.
Vigilance over
Railway Affecting tanks during heavy rains –
(1) the Divisional Engineer and the Assistant
Engineer should arrange with the local authorities/village headman in whose jurisdiction
‘Railway Affecting’ tanks are situated to watch them during periods of heavy
rain and give timely intimation to the nearest Station Master, if there is
likelihood of any tank failing. The Station Master will telephone/ telegraph
reports received from village Headman to the Permanent Way Inspector, Assistant
Engineer and Divisional Engineer.
(2) When the railway line is threatened, the Assistant
Engineer and Permanent Way Inspector shall take adequate steps to ensure the
safety of Railway property and staff and arrange patrolling of the line and or
post watchmen with necessary equipment at the place or places threatened and advise
the Divisional Engineer accordingly.
(3) All the Bridges which are likely to be affected
by Railway affecting tanks or other storage works should be provided with a tablet
on top of one of the parapets, with the letters RAW engraved on it, followed by
an arrow mark pointing in the direction of the railway affecting storage work
in question.
(4)
If the bridge in whose catchment a Railway affecting tank is located is classified
as a vulnerable location, stationary watchmen should be posted during monsoon.
( e ) Over
Dimensional Consignment –
Over Dimensional Consignment may be brought
out here that the net clearance between the consignment as loaded and the fixed
structure should be calculated after making an allowance from the gross
clearance of 75 mm for bounce in the vertical direction on a straight track. In
case of curved track the following additional factors should be taken into
account.
- Horizontal
Clearance – Allowance for lean due to super elevation and over head due to
curvatures additional lurch on curves.
- Vertical
Clearance – Vertical tilt to be added to the height of consignment.
Depending on the dimensions of the fully
loaded consignments after allowing the extra clearance.
(
f ) Scour-
The maximum scour
depth in a stream can be ascertained when ever possible by actual sounding at
or near the site proposed for the bridge during or immediately after a flood.
Before the scour holes have had time to
silt up due to allowance should be made in the observed depth for increase in
scour resulting from-
- The designed discharge being greater than the
flood discharge during which the scour was observed.
- The increase in velocity due to the obstruction
in flow caused by construction of the bridge.
Where the above practical method of determining
scour is not possible the following theoretical method may be used as a guide
when dealing with natural streams is alluvial beds. D = 0.473 [ Q / F ]⅓
Where
D = Depth of scour below HFL for regime conditions in a stable channel in
meters.
Q = Design discharge in cumecs.
F= Silt factor = 1.76 √ m , m is the
mean diameter of particles in mm.
(
g ) Pressure filters: -
These are just like small rapid sand filters placed
in closed vessels. Water passed under pressure such filters are located in
airtight vessels. Water from the sedimentation tanks is pumped into the filter
by mean of pumps. The pressure varies from 3 to 7 kg pressure. Filters are classified as –
1)
Horizontal
pressure filter.
2)
Vertical
Pressure filter.
The diameter varies from 0.30 m to 2.75 m and height
varies from 2 m to 2.5 m in case of vertical pressure filter. In case of
horizontal pressure filters the diameter varies from 2 to 3 m and length up to
9 m. The rate of filtration is 6000 to 15000 Lit. / hr / m2 of
filter area. The cleaning is done in a similar way as in case of rapid sand
filter. In order to increase the rate of filtration air pressure is generally
maintained on the water surface.
These are less efficient than rapid sand filters in
removing turbidities and bacteria’s. The quality of water is not good. These
are preferred for treating smaller quantities of water and are best suited for
swimming pools, railway stations, private estates, individual industries etc.
( I ) Security
Patrolling –
Security Patrolling of the specified section
is done on special occasions link civil disturbances strikes etc with the
object of protect trains against any sabotage etc like tampering of track
placing of obstructions on the line etc.
( j ) Gauge
Conversion -
All the advanced countries of the world have
recognized the need for uniformity of gauge. There are a number of problems
that have cropped up on the Indian railways because of three gauges. The evil
effects due to the change of gauge ( more popularly known as break of gauge )
are numerous and some of these are enumerates below –
i. Inconvenience to
Passengers.
ii. Difficulty in
transshipment of goods.
iii. Inefficient use of
rolling stock.
iv. Hinderance to fast
movement of goods and passenger traffic.
Serious problems exist on Indian Railways due
to break of gauges but unfortunately the BG and MG systems have developed
simultaneously to such an extent the converting the whole system into one
uniform gauge at the stage has got deep financial and operational implications.
Indian Railways have however recently taken up some gauge conversion projects
totaling about 300 rout kms for converting meter gauge lines into broad gauge
lines in order to accelerate and remove bottle necks for movement of passenger
and goods traffic.
Q.8.- ( a ) What do you understand by gap survey? On what type of track is
it carried out and when? What is the follow up action.
( b ) What do you understand by distressing? On what types of track is
it generally done? What are the advantages and disadvantages of using a rail
tensor for distressing work?
Q.9.- A bridge of 2 x 3.05 m arch is distressed
and required to be rebuild. What type of new bridge would you recommended as
replacement? Explain briefly with a neat free hand sketch as to how you would
execute the work?
Q.10.- An Express train has derailed in mid section
in your jurisdiction as an AEN, you are the first officer to reach the site. On
reaching the site, you are sure that apart from serious injuries, some deaths
have also taken place. Explain in brief what action would you take in order of
precedence till a more senior officer arrives and there after.
Ans.- The following steps will be taken –
i.
Protect the train by flags/ lamps / detonators. In the case of
double line if the other lie is also affected by the accident steps should be
taken to protect both the lines.
ii.
Reason the trapped and render first aid to injured, first aid can
be given by calling doctor even from out side as well as request those who are
traveling by the train.
iii.
Preserve clues if any in case of sabotage is suspected and / or
till joint measurements are taken.
iv.
Survey the site and advice on field phone to higher authority for
relief operation required for restoration as well as for medical help.
v.
Protection of property of passangers.
vi.
Prepare dimensional sketch.
vii.
Arrangement for restoration of traffic after relief train has
arrived and in case of suspected sabotage.
viii.
Arrangement for transshipment if required.
After this immediately a message will be sent to head quarters
office through senior official giving full details of accident such as section
location, time , persons , injured, dead, relief required damage to P.Way and
structure, material and labour repaired type of track involved and if possible
probable cause of accident etc. to be given.
Q.11.- What are steps required to be taken to
acquire land for new line/ Part of the Alignment passes through Forest Land

concrete.
c) Permanent and Temporary adjustments of dumpy
level.
d) On track tamper and Off track temper.
Off Track
Tampers –
Off Track Tampers are portable tempers and
can be taken off the track in a short time. These tampers are like tools driven
by compressed air, electricity or petrol. These tampers work during the
interval between trains and do not require any traffic block. These Tampers
worked in pairs from opposite sides of the sleepers diagonally under the rail
seat in order to have maximum consolidation of ballast.
Q.13.- ( a ) What are the works require the sanction of CRS?

height above rail level for a distance of 1600 mm on either side of the
centerline of track for a road over bridge.
5. The minimum length and depth of a bridge
timber resting directly on longitudinal girders.
6. Maximum gradient that can be normally
permitted in the station yards on a new line under construction.
Q.14.- The roof of a rectangular hall 6.00 m wide
and 21.00 m long is supported by rectangular RCC beams located 3.00 center to
center. Assuming the thickness of slab to be 10 cm. design an intermediate beam

Rail
Tensors –
For distressing and permanent repairs Indian
Railway have procured a few Rail Tensors either of hydraulic type called hydro
stressors or of mechanical type called mechanical rail tensor.
A hydro stressor consists essentially of a
hydraulic pump which transmits its force through connecting vans to clamps
which grips the rail. In case of mechanical tensor the force is exerted
mechanically by longitudinal jacks by means of this force the rail can be
pushed or pulled to a desired length. In case of pushing the force should not
exceed 30 tons otherwise the track is likely to buckle on that account. The
rail are however normally pulled only during the distressing operations. The
rail tensor is capable of distressing a rail at any time when the rail
temperature is less than distressing temperature.
