SPECIAL CONDITION & SPECIFICATION FOR EARTHWORK.
1.
GENERAL
1.1
Earthwork shall be done generally in accordance with provision of General Conditions of Contract and Central
Railway Standard Specifications for Works and materials.
The book “ Guide line for Earthwork in Railway Projects” Guide line (GE:G-1) issued by Geo-technical wing of
RDSO in July 2003 known here under, as “RDSO guidelines” shall form the basis of principles for conducting all
testing and execution of work of embankments. A copy of this book can be purchased form the office of Chief
Admin. Officer (Con), Indian Railway, Chamber Bhawan, JC Road Patna at a price of Rs 100/-.
Standard sections for Earthwork in formation, cutting, blanketing for single line, double line conventional doubling
are given in the Indian Railways Permanent Way Manual 2004 and Indian Railways Code for Engineering Dept.
1993,which are Government of India’s priced publications. However, a set of such standard sections can be
purchased from the office of Chief Admin. Officer(Con), Indian Railway, Chamber Bhawan, J C Road Patna at a
price of Rs 100/-.These sections are for guidance of contractor to assess the type of work involved but the actual
dimensions/side slopes etc. may vary to some extent depending on local conditions.

Where an embankment is being extended in width, the slope of the existing embankment shall be benched as
per specification of GCC and the cost for the same shall be included in the through rate and shall not be
payable separately.
(b) Before commencing the work, Labeling as specified in GCC & Central Railway Standard Specifications for
Works and materials shall be done.
PAYMENT.
Payment shall be made on finished cross sectional quantities, cross sectional areas at various points shall be worked
out and the arithmetic mean of the areas, at any two such continuous points multiplied by the horizontal distance
between these two points measured along the centerline of the alignment shall be taken as the quantity of earthwork
between the two points on which the payment shall be made. The contractor shall have no claim for the quantities
over and above the payments on account of subsidence, base settlement, wastage or guttering due to rain, floods,
wind, wave wash etc. All bridges and other gaps shall be deducted in full from the quantity of the earthwork.
SETTLEMENT ALLOWANCE: Where the embankment is compacted to specified dry density mentioned
hereunder, no allowance for settlement of the bank shall be made, where the bank has
been formed by dumping earth, light tamping, and/or passing a monsoon over it, necessary allowances for
settlement as specified in the GCC shall be made.
All payments shall be made in accordance with items given in the “Schedule of Items” only. Any
arrangements/works required to be done to achieve the work defined in various Items of the “Schedule of Items”
shall be done at contractor’s cost without any extra payment and the Contractor should include such expenses in the
rates quoted against the said items.
While making embankment, earth shall not be dumped in any standing water at the location where embankment has
to be constructed. If there is any standing water, the same shall be drained or pumped out completely before any
earth is dumped in this area. In case of draining out or pumping out water, no extra payment will be made to the
contractors and quoted rates for earthwork shall cover all such charges.
There shall be only two classifications of soil, e.g. (a) All types of soil except those requiring blasting for excavation
(b) those requiring blasting. All the payments for excavations in cuttings shall be made as per the Schedule of Items
only on the basis of these two classifications.

LEAD / LIFT etc.: No separate lift / crossing of line or similar item shall be payable separately otherwise than
provided in the Schedule of items. Lead shall be payable as provided in the Schedule of Items.
Lead for the purpose of payment will be measured on a longitudinal section of the alignment from center of gravity
of the Cut to the center of the gravity of the fill, along a straight line. Measurements of distance of lead shall not be
done at site even if the contractor does not or is unable to follow this straight line. The assessment of lead is a
drawing table exercise. The L-section shall be divided into segments, each of appropriate and suitable length, and
volume of earthwork in each segment calculated.
Segments of cut and fill will then be matched and lead measured from L-section from center of gravity of cut to
center of gravity of fill, in such a way that the total amount payable on the lead is the least. For this purpose, spoils
are not to be lead across obstruction caused by waterways with major bridges unless a road bridge exists by the side
of the alignment. Waterway with minor bridges shall be ignored because contractor is expected to build temporary
culverts across them on its own cost for leading spoils. It is desirable that the contractor before commencing work
draws the lead chart in L-section based on the above guidelines and tentatively decides lead and fills area. The
contractor shall try to stick to this lead during execution of the work. The contractor in his rate, if any, shall cater for
variations.
The spoils from cuttings shall normally be utilized for earthwork in embankment. Where the cutting spoil has been
used for making embankment, payments shall not be made for both cuttings as well as embankments. Only one
payment, i.e., for cutting shall be allowed. However, lead over free lead (100 M) will be paid separately as provided
in the schedule of the work. Surplus, unsuitable spoils shall be dumped in neat stacks on Railway land or disposed
off as directed by Engineer at site for which no extra payment will be made.
Stone excavated from cuttings, which may be considered useful for use as building stone, for pitching or for
breaking into ballast or chips shall be stacked separately by the contractor as directed by the Engineer at site. This
stone will be property of the Railway and may be issued as Railway materials to the contractors as pitching etc. in
accordance with relevant Item of L&M Schedule.
If any service roads, culverts, bridges etc. are to be built, the contractor shall build the same at his own cost.,
including ramps for transporting earth to make embankment, all the service roads are to be maintained by the
contractor at his own cost. No separate payment for such works shall be made.
The contractor shall break all clods / lumps of soil and fill up all hollows in the earthwork in embankment by light
tamping / consolidation which may be achieved by a few passes of plate vibrator or a suitable type of roller. The
rates in items in earthwork in embankment shall include this.
The contractor may be asked to use Geo-Synthetics / Geo textiles in the embankment if it is found that the use of
Geo-synthetics reduces the overall cost considerably. In such an event, special rates and conditions shall be
separately negotiated with the contractor, but the contractor shall have no claim for reduction in quantities of other
items. At the time of such negotiations, the Railway shall obtain a “No Claim “certificate to this effect. The Railway
also reserves the right to get the installations of the Geo-synthetics / Geo textiles etc. executed through other
agencies
The borrow pits shall be kept sufficiently away from the toe of the embankment to prevent base failures. The
contractor may carry out a stability analysis to decide the distance. In case such analysis is not done, this distance of
borrow pits from the toe of the bank shall be minimum of 3.0 meter + height of the bank.
The work of bolder pitching, turfing etc. Shall be carried out under CR/USOR 2012 unless other wise specified.
Turfing shall be done during monsoon period only. The contractor shall take care of the turfing including watering of
the turfing, in case of failure of monsoon, till the sods/seeds take firm roots. The sods/seeds shall be of approved
quality.
SOIL EXPLORATION/ TESTING
The contractor shall arrange for testing of the soil at his own cost without any extra payment for every 500 m to
ascertain the suitability of the soil for formation of embankment, to obtain its heavy proctor density characteristic

(d)
In situations where soils for construction of embankment consist of cobbles, boulders, rocks or waste
fragments etc largest size of material should normally not be greater than 2/3 rd of the loose layer thickness.
However it should be ensured that after every 1 to 3 meter of such construction a 30cm layer of compacted
soil (other than unsuitable soil for construction) be provided. A detailed slope stability analysis also needs to
be carried out to ensure stability of such embankments. (Para No 5.2.2 of RDSO GUIDELINES FOR
EARTHWORK IN RAILWAY PROJECTS)
(e)
The soil shall be of “Low” “Potential expansivity” also called degree of expansion (refer IS: 2911- Part III).

6.2
Top 1m of the embankment shall be constructed with earth with liquids limit not exceeding 45 to avoid shrinkage,
cracking of soil; etc. during change of weather. In case such soil is not available at a reasonable cost, the Engineer
may permit the complete bank to be constructed out of the earth as available and increase the thickness of the
blanketing suitably.
6.3
The moisture content of the soil, which the contractor brings to site for making embankment, should be appropriate
for compaction as specified in these specifications, otherwise he has to make arrangement for adding extra moisture
or drying the soil to achieve the desired moisture content.
6.4

7.
COMPACTION :
7.1
Before work is commenced, the contractor is advised to conduct, field compaction trials for his own guidance so that
compaction is efficiently and economically achieved. This trial should also be used to assess the thickness of the
loose layer of soil that should be adopted for formation of the bank, as well as to determine the most efficient type of
rollers. RDSO guidelines have given the suitable, type of roller and the same may be taken as guidance.
7.2
Water, if required, for adding to the earth shall be arranged free of cost by the Contractor himself.
Page 89 of 103

7.4
7.5
8.
The compaction of soil is essentially required for obtaining a uniform soil mass of desired density and known soil
properties. The method of compaction should, therefore, be shown accordingly.

8.1
After site clearance all pockets and depressions left in the soil, if any, shall be made good and compacted. Generally
Earthwork shall be done in layers not exceeding 300 mm thick in loose state and compacted with suitable roller to
obtain the specified density as per IS: 10379 –1982. The number of passes of the roller and the optimum thickness of
each layer will be fixed after carrying out field trials with the roller proposed to be used from time to time from
location to location. The main criteria are being to obtain the maximum density achievable uniformly.
8.2
Cohesionless soils shall be compacted to get a minimum density index (relative density) of 70% as obtained in
accordance with IS: 2720(Pt. XIV) – 1983.
8.3
All other types of soils when compacted shall attain at least 98% of the maximum dry density as determined using
heavy compaction in accordance with IS: 2720 (Pt. VIII) – 1983 followed by field trials as per IS: 10379 – 1982. In
case, there are difficulties in achieving 98% of the MDD values as obtained by Laboratory test, in the field trials, the
same may be relaxed upto 95% of MDD with the specific approval of Chief Engineer/construction, recording
reasons of such relaxation
8.4
If the soil is dry, water shall be sprinkled either in the borrow pit or over the spread layer, as convenient in order to
obtain a workable moisture content before rolling is commenced. Where the natural moisture content of borrow pit is
high, compaction in higher moisture contents can be allowed by the permission of Engineer-in-charge.
8.5
Each layer shall be compacted to the specific density over its entire width commencing from the two sides, before
another layer is started.
8.6
While compaction it shall be ensured that there is minimum overlap of 150 mm between each run of the rollers.
8.7
Care should be taken during the compaction operation to slope the surface of the bank to facilitate the shedding and
to minimize the absorption of rainwater, particular attention being given to the prevention of ponding.
8.8
The Railway shall ascertain the density of each layer of compacted soil by testing adequate number of soil samples.
8.9
The quality of compaction work shall be determined by considering the Mean Density of the samples collected
mostly on either side of the center line at intervals of 10 M or so with a few taken at random near the two sides in
each layer. The Mean Dry Density shall be equal to or exceed the minimum specified density. In no individual case
the density be less than the minimum value specified by more than 2% otherwise further rolling shall be done at the
appropriate location.
8.10
The contractor shall be allowed to lay a further layer of soil only after the compaction of a particular layer has been
found satisfactory.
8.11
The top of the formation shall be finished to a slope of 1 in 30 away from the centers.
8.12
Extra width of 50 cm shall be rolled on either side, which after finishing the bank up to final height shall be dressed
to final cross section by removing the loose earth or extra width. No extra payment for this extra width shall be made
9.
In parts to embankment which are inaccessible to the specified rolling equipment, e.g. around and in contact with
culverts, abutments or in proximity to structure where rolling equipment will either not be possible to operate, or not
permitted to operate, compaction shall be accomplished by hand tamping followed with plate vibrators or suitable
mechanical means in layer of thickness not exceeding 150 mm. In such areas, the maximum dry density to be
achieved as a result of compaction shall not be less than 90% of the maximum value achievable at that moisture
content.

Concrete shall be thoroughly compacted by vibration or other means during placing and worked around the
reinforcement, tendons or duct formers, embedded fixtures and into corners of the formwork to produce a dense
homogenous void-free mass having the required surface finish. When vibrators are used, vibration shall be done
continuously during the placing of each batch of concrete until the expulsion of air has practically ceased and in a
manner that does not promote segregation. Over vibration shall be avoided to minimize the risk of forming a weak
surface layer. When external vibrators are used, the design of formwork and disposition of vibrator shall be such as
to ensure efficient compaction and to avoid surface blemished. Vibrations shall not be applied through reinforcement
and where vibrators of immersion type are used, contact with reinforcement and all inserts like ducts etc., shall be
avoided. The internal vibrators shall be inserted in an orderly manner and the distance between insertions should be
about one and half times the radius of the area visibly affected by vibration. Additional vibrators in serviceable
condition shall be kept at site so that they can be used in the event of breakdowns.
Mechanical vibrators used shall comply with IS: 2505, IS: 2506, IS: 2514 and IS: 4656.
1.8.11 Construction Joints:
A PSC girder shall be cast in single pour of concrete without any cold joints or construction joints. Even for other
bridge structures, construction joints shall be avoided as far as possible and in no case the locations of such joints
shall be changed or increased from those shown on the drawings, except with express approval of the Engineer. The
joints shall be provided in a direction perpendicular to the member axis. Sequencing of concrete placement should be
organized in such a way that cold joints are totally eliminated. The sequence of concreting shall be submitted for
approval of Railway prior to concreting of the structural element.
All construction joints, if approved shall be treated with epoxy compound after preparing the surface with V-notch,
cleaning etc. complete to the satisfaction of the Engineer.
1.8.12 Concreting Under Water:
When it is necessary to deposit concrete under water, the methods, equipment, materials and proportions of mix to
be used shall be got approved from the Engineer before any work is started. Concrete shall contain 10% more
cement than that required for the same mix placed in the dry.
Coffer dams shall be sufficiently tight to ensure still water conditions, if practicable, and in any case to
reduce the flow of water to less than 3 meters per minute through the space into which concrete is to be deposited.
Coffer dams in still water shall be sufficiently tight to prevent loss of mortar through the joints in the walls. Pumping
of water shall not be done while concrete is being placed or until 24 hours thereafter. To minimize the formation of
laitance, great care shall be exercised not to disturb the concrete as far as possible while it is being deposited.
Page 101 of 103
All under-water concreting shall be carried out by tremie method only, using tremie of appropriate diameter.
The number and spacing of the tremie’s should be worked out to ensure proper concreting. The tremie concreting
when started should continue without interruption for the full height of the member being concreted. The concrete
production and placement equipment should be sufficient to enable the underwater concrete to be completed
uninterrupted within the stipulated time. Necessary stand-by equipment should be available for emergency situation.
The top section of the tremie shall have a hopper large enough to hold one full batch of the mix or the entire contents
of the transporting bucket as the case may be. The tremie pipe shall not be less than 200mm in diameter and shall be
large enough to allow a free flow of concrete and strong enough to withstand the external pressure of the water in
which it is suspended, even if a partial vacuum develops inside the pipe. Preferably, flanged steel pipe of adequate
strength for the job shall be used. A separate lifting device shall be provided for each tremie pipe with its hopper at
the upper end. Unless the lower end of the pipe is equipped with an approved automatic check valve, the upper end
of the pipe shall be plugged with a wadding of gunny sacking or other approved material before delivering the
concrete to the tremie pipe through the hopper, so that when the concrete is forced down from the hopper to the pipe,
it will force the plug (and along with it any water in the pipe) down the pipe and out of the bottom end, thus
establishing a continuous stream of concrete.
It will be necessary to raise slowly the tremie in order to allow a uniform flow of concrete, but it shall not be
emptied so that water is not allowed to enter above the concrete in the pipe. At all times after placing of concrete is
started and until all the required quantity has been placed. The lower end of the tremie pipe shall be kept below the
surface of the plastic concrete. This will cause the concrete to build up from below instead of flowing out over the
surface and thus avoid formation of layers of laitance. If the charge in the tremie is lost while depositing, the tremie
shall be raised above the concrete surface and unless sealed by a check valve, it shall be replugged at the top end, as
at the beginning, before refilling for depositing further concrete.
1.8.12 Protection and Curing:
Concreting operations shall not commence until adequate arrangements for concrete curing have been made by the
Contractor.
Curing and protection of concrete shall start immediately after compaction the concrete to protect it from:
a)
Premature drying out particularly by solar radiation and wind
b)
High internal thermal gradients
c)
Leaching out by rain and flowing water
d)
Rapid cooling during the first few days after placing
e)
Low temperature
f)
Vibration and impact which may disrupt the concrete and interfere with its bond to the reinforcement.
Where members are of considerable size and length, with high cement content accelerated curing methods maybe
applied, as approved by the Engineer.
1.8.13.1 Water Curing
Water for curing shall be as specified suitable for concreting.
Exposed surface of concrete shall be kept continuously in a damp or wet condition by ponding or by
covering with a layer of sacks, canvas, Hessian or similar materials and shall be kept constantly wet for a period of
not less than 28 days from the date of placing of concrete.
1.8.13.2 Curing compound
Curing compound shall normally not be used. If proposed to be used, they can be permitted at selected locations, at
the approval of the Engineer.
1.8.14 Finishing
Immediately after removal of forms, exposed bars or bolt, if any, shall be cut inside the concrete member to a depth
of at least 50mm below the surface of the concrete and the resulting holes filled with cement mortar of dry pack
consistency.
All construction and expansion joints in the completed work shall be left carefully tooled and free from any
mortar and concrete. Expansion joint filler shall be left exposed for its full length with clean and true edges.
The finished surfaces of concrete after removal of formwork should be such that no touching up is required.
All fins caused by form joints, if any, shall be ground using electric surface grinder.
Immediately on removal of forms, the concrete work shall be examined by the Engineer before any defects
are made good.
a)
The work that has sagged or contains honeycombing to an extent detrimental to structural safety or
architectural appearance shall be rejected.
b)
Surface defect of a minor nature may be accepted. On acceptance of such work by the Engineer, the same
shall be rectified as directed by Engineer.
