bore holes to be drilled shall be marked in circles with white paint. These shall be inspected by
the contractor’s agent. Bore holes shall be of a size that the cartridge can easily pass down. After
the drilling operation, the agent shall inspect the holes to ensure that drilling has been done
only at the marked locations and no extra hole has been drilled. The agent shall then prepare
the necessary charge separately for each bore hole. The bore holes shall be thoroughly cleaned
before a cartridge is inserted. Only cylindrical wooden tamping rods shall be used for tamping.
Metal rods or rods having pointed ends shall never be used for tamping. One cartridge shall be
placed in the bore hole and gently pressed but not rammed down. Other cartridges shall then be
added as may be required to make up the necessary charge for the bore hole. The top most
cartridge shall be connected to the detonator which shall in turn be connected to the safety
fuses of required length. All fuses shall be cut to the length required
before being inserted into the holes. Joints in fuses shall be avoided. Where joints are
unavoidable a semi-circular nitch shall be cut in one piece of fuse about 2 cm deep from the end
and the end of another piece inserted into the nitch. The two pieces shall then be wrapped
together with string. All joints exposed to dampness shall be wrapped with rubber tape.
The maximum of eight bore holes shall be loaded and fired at one occasion. The charges shall be
fired successively and not simultaneously. Immediately before firing, warning shall be given and
the agent shall see that all persons have retired to a place of safety. The safety fuses of the
charged holes shall be ignited in the presence of the agent, who shall see that all the fuses are
properly ignited.
Careful count shall be kept by the agent and others of each blast as it explodes. In case all the
charged bore holes have exploded; the agent shall inspect the site soon after the blast but in
case of misfire the agent shall inspect the site after half an hour and mark red crosses (X) over
the holes which have not exploded. During this interval of half an hour, nobody shall approach
the misfired holes. No driller shall work near such bore until either of the following operations
have been done by the agent for the misfired boreholes.
(a) The contractor’s agent shall very carefully (when the tamping is of damp clay) extract the
tamping with a wooden scraper and withdraw the fuse, primer and detonator. After this a fresh
detonator, primer and fuse shall be placed in the misfired holes and fired, or
(b) The holes shall be cleaned for 30 cm of tamping and its direction ascertained by placing a
stick in the hole. Another hole shall then be drilled 15 cm away and parallel to it. This hole
shall be charged and fired. The misfired holes shall also explode along with the new one.
Before leaving the site of work, the agent of one shift shall inform another agent relieving him
for the next shift, of any case of misfire and each such location shall be jointly inspected and the
action to be taken in the matter shall be explained to the relieving agent.
The Engineer-in-Charge shall also be informed by the agent of all cases of misfires, their causes
and steps taken in that connection.
General Precautions during blasting work.
For the safety of persons red flags shall be prominently displayed around the area where
blasting operations are to be carried out. All the workers at site, except those who actually ignite
the fuse, shall withdraw to a safe distance of at least 200 metres from the blasting site. Audio
warning by blowing whistle shall be given before igniting the fuse.
Improvement of Illumination at New Port Bhavnagar 2026-27
Blasting work shall be done under careful supervision and trained personnel shall be employed.
Blasting shall not be done within 200 metres of an existing structure, unless specifically
permitted by the Engineer-in-Charge in writing.
All procedures and safety precautions for the use of explosives drilling and loading of explosives
drilling and loading of explosives before and after shot firing and disposal of explosives shall be
taken by the contractor as detailed in IS 4081, safety code for blasting and related drilling
Precautions against Misfire during blasting work
The safety fuse shall be cut in an oblique direction with a knife. All saw dust shall be cleared
from inside of the detonator. This can be done by blowing down the detonator and tapping the
open end. No tools shall be inserted into the detonator for this purpose.
If there is water present or if the bore hole is damp, the junction of the fuse and detonator shall
be made water tight by means of tough grease or any other suitable material.
The detonator shall be inserted into the cartridge so that about one third of the copper tube is
left exposed outside the explosive. The safety fuse just above the detonator shall be securely
tied in position in the cartridge. Water proof fuse only shall be used in the damp bore hole or
when water is present in the bore hole.
If a misfire has been found to be due to defective fuse, detonator or dynamite, the entire
consignment from which the fuse detonator or dynamite was taken shall be got inspected by the
Engineer-in-Charge or his authorized representative before resuming the blasting or returning
the consignment.
Where blasting operations are prohibited or are not practicable, excavation in hard rock shall be
done by chiselling.
In ordinary rock excavation shall be carried out by crowbars, pick axes or pneumatic drills and
blasting operation shall not be generally adopted. Where blasting operations are not prohibited
and it is practicable to resort to blasting for excavation in ordinary rock, contractor may do so
with the permission of the Engineer-in-Charge in writing but nothing extra shall be paid for this
If the excavation for foundations or drains is done to a depth greater than that shown in the
drawings or as required by the Engineer-in-Charge. The excess depth shall be made good by the
contractor at his own cost with the concrete of the mix used for levelling/ bed concrete for
foundations. Soft/ defective spots at the bed of foundations shall be dug out and filled with
concrete (to be paid separately) as directed by the Engineer-in-Charge.
In all other cases where the excavation is taken deeper by the contractor, it shall be brought to
the required level by the contractor at his own cost by filling with earth duly watered,
consolidated and rammed.
In case the excavation is done wider than that shown on the drawings or as required by the
Engineer-in-Charge, filling wherever required on this account shall be done by the contractor at
Only the excavation shown on the drawings or as required by the Engineer-in-Charge shall be
measured and recorded for payment except in case of hard rock, where blasting operations have
been resorted to, excavation shall be measured to the actual levels, provided the Engineer-in-
Charge is satisfied that the contractor has not gone deeper than what was unavoidable.
The excavation shall be done manually or by mechanical means as desired by Engineer-in-
Charge considering feasibility, urgency of work, availability of labour /mechanical equipment’s
and other factors involved Contractor shall ensure every safety measures for the workers.
Neither any deduction will be made nor any extra payment will be made on this account.
Improvement of Illumination at New Port Bhavnagar 2026-27
The measurement shall be done and paid in cum of work completed, shall be inclusive of all the
works as per specification as directed by Engineer in Charge (EIC).
Item No. 9 - Excavation for foundation for depth from 1.5 m to 3.0 m including sorting out and
stacking of useful materials and disposing of the excavated stuff up to 50m lead.
