ascertaining that no body is in the area of blasting. _

Before firing, the circuit shall be checked by a suitable apparatus.

After firing, with or without an actual blast, the contact between the firing

cable and the source of current shall be out of before any persons are allowed

leave the shelters.

During storm, charging with electrical detonators shall be suspend. The

charges already placed into the holes shall blast as quickly as possible,

after taking all the safety precautions & giving necessary warning signals. if

this is not possible the site shall be abandoned till the storm has passed.

Precautions after Blasting

After the blast, the Supervisor shall carefully inspect the work and satisfy

himself that all the charges have explosed.

After the blast takes place in underground works the workmen shall not be

allowed to got to the place till all the toxic gases are escaped from the frace.

Misfires:

lt is suspected that part of the blast has failed to fire or is delayed, suffiecient

time shall be allowed to lease before entering the danger zone, when fuse

and blasting caps are used a safe time should be allowed and then the

Supervisor, alone shall leave the shelter to see that misfire.

Drilling near the hole that has mis-tired shall not be perm_itted until one of the

two following operation have been carried out by the Supervisor.

1. The Supervisor should very carefully (When the tamping is of damp

clay)extract the tamping with a wooden scraper orjet of water or compressed

air(using a pipe of soft material) and withdraw the fuse with the primer

anddetonator attached. A fresh primer and _detonator with fuse shall then

beplaced in this hole and fire. `

2. The Supervisor shall get one of the tamping cleared off and indicate

thedirection by placing a stick in the hole. Another hole may then be drilled

atleast 23 cm. away and parallel to it. This hole should then be charged

andfired. The balance of the cartridges and detonators found in the muck

shallbe removed.

Before leaving his work, the Supervisor should inform the Supervisor of

therelieving shift of any case of mis-fire and shall point out the position with ared cross

denoting the same and also state what action, if any, he has takenin the matter.

The Supervisor shall at once report to the office all case of mis-fire, thecause of

the misfire the steps taken in connection there with.The names of the Supervisor-in-

charge of day and night shift must be noteddaily in the contractor's office.

lfamis-fire has been found to be due to defective detonator or dynamite the

whole quantity of box from which the defective articles were taken must be

returned to the authority as may be directed by the Engineer-in-charge for

inspection to as certain whether whole box contains defective materials.

Re-drilling the holes that have mis-fired either wholly or partly shall not be

permitted.

creased at the discretion of the Engineer-in-charge when the charging opera-

tion fails to produce concrete of the required uniformity of compositon and

consistency within the batch and from the batch of batch Contractor shall not

be entitled for any extra payment for such increase in mixing time. Excessive

mixing requiring the addition of the water to preserve the requried concrete

consistency shall be avoided. If the mixing and charging operations are such

that the required uniformity of the concrete is obtained in shorter mixing time

then the minimum time may be shortened under orders of the engineer-in-

charge. mixing shall be done by Mechanical means only.

lnaddition to the 28 days strength tests, the Executive Engineer may at

hisdiscretion take 7 days strength tests and/or 3 days (accelerated curing)strength tests

and fix up the relation between such strength and 28 daysstrength after studying the

actual values released. lfat any time the tests

indicate that the strength may not be achieved as specified work of layingshall be

suspended untill the reasons for low strength have been investigatedand corrected. The

contractor shall comply there with without such suspension being made a reason for

any claim. The suspension of work shall alsobe ordered when the variation in the

planks and scantlings shall be straight and all edges and planes shall be

straight and free from warps, partially seasoned softwood is generally pref-

erable for form works as it is difficult to drive nails in hard wood. The dimensions of

scantlings should conform to the design. The strenght of the woodnot be less than that

assumed in the design.

ln metal forms, steel sheets of the designed guage strengthened withframing of angles

or other section shall be used.Wooden forms may also be lined with thin steel sheets or

plywood to give

the.required surface or finish _

4.10.4 Fabrication

The timber planks and scantlings of the designed dimensions shall be used

in the form work with appropriate spacing of stuts, yokes, joists, girders etc.

as provided in the designs. All timber in contract with concrete shall be brought

on one face and two edges the unwrought face being on the outside. The

joints should be made mortar tight. This may be done either by providing

tongued and grooved or reverted joint or by cauling or nailing metal strips or

applying ahdesive tape on the joints. The form shall be built with sufficient

strenght and rigidity and held in shape by bolts, clamps, ties nails, or other

143


contrivance to prevent distortion of collapse due to pressure of concrete

and other loads incidental to the construction operations. The nuts and bolt

heads in side the form work adjoining the concrete should be counter sunk.

The form work should allow finished concrete to have a smooth surface and

contirm to the shapes, lines and dimensions shown on the plans and true to

the line and grade. The effect of vibrtion shall be taken into account in the

design and fabrication of the form and false work.

4.10.5 Treatment of the Inner Sides of Froms

Before placing concrte the inner side of the forms which come in contractwith

the concrete shall be coated with mineral oil or any other suitable materials approved

by the Engineer-in-charge. which will prevent adhesion ofconcrte to the forms but will

not discolour the concrete. When oil is used, it

shall be applied before reinforcement isplaced. Care shall be taken to seethat

reinforcement does not come in contract with coating. All chipping, sawdust and other

rubbish shall be removed from the interior of the formsbefore concreting.

4.10.5 False Work

Flase work shall be built on foundation or base of sufficient strength to carrythe

loads without settlement. False work which can not be found on solidfooting must be

supported by piles or other similar devices. False work shallbe designed to carry the full

loads including that the construction operationcoming upon it.

4.10.7 Errection and Removal of Forms

The false work and form work shall be erected with an eye for absolute

safety of the form work and concrete work before and after pouring con-

crete. Watch should be kept to see that the behavior for centering and form

is satisfactory during concreting. Erection should also be such that it would

allow removal of forms in proper sequences without damagind either the

concrete or the forms to be removed later. _

lf there is failure of false work and/or work the Contractor shall be

responsible for all the consequent damages to work, injury of life and dam~

age to property and make good the damage at his cost.

1. Before placing concrete the surface of form shall be oiled with a suitable

nonstaining oil such as raw linseed oil so as to prevent stricking of

concrete and facilitate the removal of form.

2. The oil shall cover the forms fully and evenly without excess over drin. Care

shall be taken to prevent oil from getting on the surface of the construction

joints and on reinforcement bars. Special care shall be taken to oil throughly

the froms strips for narrow grroves so as to prevent swelling of the forms

and the consequent damage to concrete prior to or_during 'removal of forms.

Immedialtely before concrete is place, care shall be taken to see that all

144


froms are in proper alignment and the supports and fixtures are throughly

secured and tightened.

3. Where forms for continuous surface are placed in successive units, the

form shall fit tightly over the completed surface so as to prevent leakage of

mortar from the concrete and to maintain accurate alignment of the surface.

4. Forms shall be left in place until their removal is authorized and shall then be

removed with care so as to aviod injury to concrete.

5. Removal of forms shall ever to started until the concrete is thoroughly set and

hardened adequately to carry its own weight, beside the live load which is

likely to come on the work during constructions. The length of item for which

the forms shall remain in place shall be decided by the Engineer-in-charge,

with reference to weather conditions shape position often structure or structural

member andthe nature and amount of dead and live loads.

In normal circumstances forms shall be struck after the expiry of the

following period. ~

a) Beam sides, walls , columns (Unloaded) 72 Hours.

b) Slabs and arches. (Props left under) 4 days.

c) Props to slabs and arches. 14 days,

d) Beams sofit (Props left under) 21 days.

e) Props to beams. 21 days.

f) Lean concrete (Side). 2 days.

In no case shall froms be removed until there is assurance that removal can

be complished without damaging the concrete surface. No loads will be

allowed to damage the concrete surface. Heavy load shall not be permitted

until the concrete has reached its designed strength. The forms shall be

removed with great caution and without harming the structure or throwing

heavy forms upon the floor.

4.10.8 Re-Use of Forms Etc.

Forms required to be used more than once shall be maintained in

serviceable conditions and shall be thourghly cleaned and smoothened be-

fore reuse. Where metal sheets are used for lining forms the sheets shall

be placed and maintained on the forms with minimum amount of wrinkles

lumps or other imperfection. All forms shall be checked for shape and strength

before reuse.

4.10.9 Inspection

The forms and false work will be inspected, checked and approved by the

Engineer-in-charge before concreting is commenced. But this will not

relieve the Contractor of his reponsibility for strength adequacy and safety of

the form and flase work. . ` ,

145


4.11.0 Placing Concrete

4.11.1 Concrete shall be placed only in location where authorised and no

concrete or mortar shall be placed until formwork, installations of embeded

parts, preparation of surface or necessary clean up has been approved.

4.11.2 Rock Surface

Rock surface upon or against which concrete is to be placed, shall be

prepared as specified in section of excavation for foundation.

4.11.3 Masonry Surface A

1. Masonry surfaces on which or against which concrete is to be placed shall

be prepared as described in para 5.2.1 and 5.2.2 of section 5. The unit rate

for masonry shall cover the cost of such preparation.

2. lf the old layer of masonry which has been paid for is required to be removed

as mentioned in para 2-2(a) above, it shall be back filled with concrete along

with upper concrete layer at not extra cost.

4.11.4 Concrete Surfaces

Before laying of concrete the surface of the concrete in day to day work shall

be cleaned by a wire brush and jet of water, so that the surface is throughly

cleaned and wetted but pools of water are avoided. lf the old concrete sur-

face has remained exposed for more than two week, it shal be prepared and

roughened by chipping to a depth of 5 to 8 cm. The unit rate of concrete shall

cover the cost of such preparation and also the cost of cement mortar. The

concrete remvoed for roughening shall not be paid for.

4.11.5 All Surfaces

1. The cleaned rock, masonry or concrete surface shall be applied with

cement slurry and then cement mortar coat as described is para 1O_2.2_

2. The first few batches of concrete mayif as required contain half the regular

size of coarse aggregate without any extra claims.

3. The cost of such preparation work stands included in the unit rate of cernent

concrete.

4.11.6 Time For Use

All concrete shall be placed directly in its final postion within thirty minutes of

mixing. Any concrete which has become so stiff that proper placing cannot

be assured without retempering shall be wasted and shall not be paid for. All

surface fofroms and metal work including reinforcement bar that have be-

come entrusted with dried mortar of grout concrete previously placed shall

be cleaned of all such mortar or grout before surrounding or adjacent con-

crete is placed.

146


4.11.7 Method of Placement

Before starting placing of concrete, it should be made certain that thetransporting and

placing equipment is clean in proper order and thatequipment along with the operating

staff is arranged to deliver the concrete inthe final positons without undue delays and

objectionable segregation. The

methods and the equipment used fortransport and placing of concrete shallbe such as

will permit the delivery concrete of the required consistency intothe work without

objectionable segregation porosity or excessive loss ofworkability. Excessive segregation

from whatever cause shall be prevented

in handling and placing operation by avoiding or controlling Iaterial movement of the

concrete as in dumping at an angle depositing continuously atone point and allowing

the concrete to flow. Concrete shall not be droppedfrom excessive and from free fall

should be kept to a minimum. Concrete

shall be deposited in continuous horizontal layres in a thickness of approximately

3Ocm.‘ in normal work to 4 cm for mass concrete except that notingherein shall be

constructed to permit placement of the additional horizontallayers of mass concrete

before the entire area to be concreted is covered

by previous layers. On flat, horizontal surface, where congestion of steelnear the forms

makes placing of steel near the forms makes placing ofconcrete difficult, a mortar of the

same cement sand ratio as used in theconcrete shall be list deposited to cover the forms

and shall stand included

in the unit rate of concrete before the entire area to be concreted is coveredby previous

layers.

4.11.8 Rate of Placing

Concreting should be continued without avoidable interuption until the

structure or section is complete or until satisfactory construction joints can

be made. Location of construction joints shall be as directed by the

Engiener-in-charge Concrete shall not be placed, faster than the placing

crew can compact it properly in placing this members and columns

precautions shall be taken against too rapid placement which may result in

movements or failure of the from dueto excessive lateral pressure. An

interval of at least 12 hours and prelerably 24 hours should elapse

between the completion of ‘columns columns and walls and the placing of

slabs beams or griders supported by them in order to avoid cracking due to

settlement. All concrete shall be placed in approximetly horizontal lifts not

exceeding 1.23 metre in thickness per day. Concrete in arches shall be

done in strips extending from one pier to another. No through joints shall be

kept in the span.

4.11.9 Concreting at Night Time

147


lfthe concrete is to be placed at night adequate lighting arrangements shall

be made as directed by the Engineer-in-charge,

4.11.10 Concreting During Rains

When concreting is required to be done or continued while it is raining shall

be seen that the concrete is not damaged due to rain while it is being trans-

ported and one placed. After placed the green concrete it shall be adequately

covered for a period of 24 hours when it will be capable for being cured by

splash of water. The surface of fresh concrete should be maintaned on a

slope sufficient for result in the self drainage of the rain water. The work shall

however to discontinued when the rains is so severe that water collects in

pools or washes the surface of the for concrete and it is not possible to

provide adequate shelter. h '

4.12.1 Compaction

All concrete shall be vibrated by mechanicl vibrator of approved type so a to

ensure dense concrete. Hand tamping and rolling shall not be used for

compaction of concrte except in special circumstances with the express

permission ofthe Engineer-in-charge _ When immersion type vibrators are

used they shall be used vertically at about 45cm. apart. The vibrators shall

be inserted to the full dept of the newly laid concrete layer. The concrete

shall be throughly compacted during depositng to get a dense concrete and

throughly worked in to the edges and corners of the form work and also

along its faces and around reinforcement in the case of R.C.C. by means of

suitable tools such as trowel and rods to get a good finish without honey-

combing. the vibrator shall however, not revibrate concrete which as com-

menced it final set. Special Care shall be taken to see that vibrator touching

the reinforcement of embeded part does not disturb the concrete below which

has commenced its final set. The concrete shall not be vibrated excessively

so as to cause segregation. _

4.12.2 Each layer of concrete, for surfaces which is required to be smooth and for

all surfaces which will be permanently exposed to the weather, and for all

surfaces next to embedded metal work shall be worked and vibrated by

mechanical vibrators of approved type only so as to obtain a concrte of

maximum density and impervious and to assure close contact of the

concrete with forms, reinforcement bars and other embedded part. Lf the methods of

transporting and placement have been conductive to air

entrainment segregation of stiffening, the work of compaction should

receive special attention.

4.12.3 For concrete surface exposed to full of water special precaution shall be

taken to minimize and to prevent surface pitting and protrusions without

resorting to over manipulation of the concrete mix to the forms. No

plastering for getting a smooth finish shall be permitted at these locations.

148


any protrusion shall be ground smooth.

4.13.0 Curing and Protection

All concrete shall be protected against injury until final acceptance.Exposed

finished surface of concrete shall be protected from the direct raysof sun for atleast 72

hours after placement. Concrete shall be kept continuously moist for not less than 21

days. Construction joints shall be cured inthe same ways as other concrete and shall

also be kept moist for atleast 72hours prior to the placing of addtional concrete upon

the joints. Approximately horizontal surfaces shall be cured by sprinkling, ponding, or by

covering, by damp sand or may be cured by the use of wet quilts or mats.Vertical

‘surfaces shall be cured by covering with wet jute bags. lf dampsand orguilting or mats.

Vertical surfaces shall be cured by covering withwetjute bags. lf damp sand or quilting is

used for curing, it shall be removed

completely later. Should the concrete the has become dry or powderythroughneglect of

curing the Contractor shall rectify the work at no extra cost. ifcuring arrangements by

the Contractor are not satisfactory the Engineer-in-charge may in his discretion engage

labour and provide material and equipment for curing and recover expenditure thus

involved from Contractor.

4.14.2 Formed Surfaces

Surfaces of concrete finished against form shall be smooth, free from

projections and filled throughly with mortar. lmmediatley upon removal froms,

all unsightley ridges or lines shall be removed and and local bulging on ex-

posed surfaces shall be remedied by tooing and rubbing. All holes left bythe

removel of fasteners shall after being reamed with toothed reamer, neatly

filled with diy patching mortar. All porous and fractured concrete and sur-

face concrete to which additions are required to bring it to the prescribed

lines shall be sharp edges and keyed shall be filled to required line with fresh

concrete used for filling the chipped opening and these shall not be less

than 8cm. in depth and the concrete filling shall be reinforced and dowelled

to the surface of the opening. Honey combed and surfaces which give a

hollow sound shall be rectiied by guniting at the Contractor's cost within the

unit rate accepted for concrete.

149


Dry patching mortar shall consist of one part of cement to 2 parts of sand byvolume and

just enough water so that the mortar so used, will sticktogether on being molded into a

ball a slight pressure of hands and will not exclude water when pressed but will leave

the hands damp. The mortarshall be placed in layers of not more than 2 cm. thickness.

After being compacted each layer shall be roughened by being scratched to provide

andeffective bond with the surrounding concrete. All patches shall be bonded

thoroughly to the surfaces of the chipped opening and shall be sound andfree from

shrinkage cracks.

4.14.4 Finishing Permanently Exposed Surface

Except as otherwise specified or directed all permenently exposedconcrete

surface and other waten/vay surface requiring durability under (except the ouley) shall

surfaces shall be wetted and

all surface pits and air bubbles filled by rubbing mortar composed of cementand fine

sand in proportion (112) in to the pits with burlap so as to secure auniformly dense and

smooth face. The rubbing shall be performed in sucha manner as to leave the surface

fee form mortar not used for filling the pits.

Should the filling operation be unduly delayed and the surfaces of the pitsbecome

coated with dust or other contaminating materials, they shall bethoroughly cleaned and

washed and shall be maintained in a moist condition, until the mortar filling is placed.

Such cleanings shall be done by means

of air and water jets and chipping of brushing or other satisfactory meanswithout

damaging the surrounding concrete. All operations in connection with the filling of

surface pits shall be handled as quickly as practicable tominimise the period during

which the concrete and mortar filling are

exposed to the drying. When the treatment of a surface has been completed the

surfaces shall be and of the same colour and texture as theadjoining concrete.

4.14.5 Finishing Concealed Surface _

For exterior concealed surfaces below ground or back fill level on like

surface not othen/vise specified, no Hnish is necessary except that sands

treaks metal pockets, honey combing or other imperfections which are of

consequence affecting strength, water tightness or protection of

reinforcing steel from corrosin, shall be corrected and repaired as prescribed

for formed surface. ‘

4.14.6 Finishing Unformed Surface

Unformed surface shall be finished by one or more of the operation ofscreeding

floating and trowelling working of the surface should be done atproper time employing

experienced men and should-be just sufficient toproduce the desired finish, Screeding

which gives the surface its

150


approximate shape by striking of surplus concrete immediately aftercompaction shall be

accomplished, by moving a straight edge or templatewith a sawing motion across wood

or metal strips that have been

established as guides. Where the surface is curved special screed shouldbe brought true

to from and grade by working it with a wooden float. lf acoarse textured finish is desired

or if the surface is to be steel trowelled asection orfinal floating should be performed

after some stiffening has occured

and the surface moisture film or shine has disappeared from the floatedsurface and

when the concrete has hardened sufficiently to prevent finematerial and water from

being worked out to the surface. Excessive trowelling particularly at an early time shall

be avioded.

4.14.7 Chipping and Roughing Concrete Surface

Surface upon or against which additional concrete is to be placed shall be

chipped and roughened to a depth not grager than 25mm. Roughing shall

be performed by chipping or other satisfactory methods and in such

manner as no to loosen, crack or shatter any part of the concrete beyond

the roughened surface. After being roughened the surface of the concrete

shall be cleaned thorughly of all losse fragments dirt and other

objectionable substances and shall be sound and hard in such conditons as

to assure good mechanical bond between old and new concrete to the depth

required to secure a satisfactory surface.

4.14.8 Dammage Due to Floods - Government Not Responsible

ln case of damage fo any of the concrete works due to floods, Government

will not be responsible and whatever corrective measures are required to be

adopted shall be done by the Contractor at his cost.

the job as and when directed. Generally for work test, samples shall be

taken for every 100 cum. of masonry and atleast once in day. Materials for

the works tests [mortar, cement, sand, water as the case may be] shall be

supplied by the Contractor free of cost and collection of samples, casting

cubes, curing and testing shall be carried out by the Government at Cost.

5.7.3 B) Standard of Acceptance

Noset of of work test cubes shall have at 28 days, a crushing strength less

than 80% of the stipulated crushing strength.The average below 80% of the

stipulated curshing strength. The average of the crushing strenght of the

three work test cubes shall be taken as the crushignstrength of the test.

For every set of 'work test' cubes which give a average 28 days crushing

strength of less than 80% of the stipulated crushing strength, a volume of

100 cubic metre of masonry shall be paid at such reduced rate as may be

decided bythe Engineer-in-charge.

lnadditon to the 28 days strength tests, the Engineer-in-charge may at his

discretion take 7 days strenth tests and hx up the relation between such

strength and 28 days strength after studying the actual values realised. lf at

any time the tests i.e. 7 days stength test indicate that the strength may not

158


be achieved as specified by the Engiener-in-charge shall have authority to

suspend the work of laying masonry until the reasons for low strength have

been investigated and corrected.

The Contractor shall comply therewith without such suspension of work

being made a reason for any claim. The Engineer-in-charge may at his dis-

cretion also order suspension ofthe work when the variation in the strength

of the individual work test cubes form average of the set is in his opinion

excessive. The Contractor shall comply with such suspension until the reaons

for the variations are investigated and corrected an such suspension shall

not be accepted as reason for any claim.

There will be no reduction in rate if the tests to the extent of 25% (1 in 40) fall

below the 80% of the stipulated strength.

if the tests to be extent of more than 25% but less than 5% (1 in 20) fall

below 80% of the stipulated strength and the coefficient of variation is not

more than 18% of the masonry construction out of such mortar will not be

rejected out paid at 95% of the rate.

Ifthe more than 5% ofthe tests fall below 80% of the stipulated strength the

masonry constructed out of such mortar shall be rejected.

5.8.1 Proporation :

The mortar shall be obtained by through mixing together the ingredients in a

mechanically operated mixer in speicihed proportions as per para5.8.2 Mode of

Mixing

The ingredients of mortar shall be properly mixed inmixers designed so as

to positively ensure uniform distribution of all the component materials

throughout the'mass at the end of mixing period. After all matrials except for

the full amount of water are in the mixer, the mixing of each batch shall

continue experience The minimum mixing period specified above assumes

proper control of the materials including water. The mixing time shall be

increased at the discretion of the Executive Engineer. when the charging

operation fails to produce the required uniformity of composition and con-

sistency within the batch and from batch to batch. The Contractor shall not

be entitled for any extra paymentof such increase in mixing time. The ex-

cessive mixing requiring the addition of water to preserve the required mor-

tar in consistency shall be avoided. lf themixing and charging operations

such that the required unifromity of mortar is botained in shorter mixing time

that than the minimum spedihed without sacrifice of needed workability, the

mixing time may be shortened under orders of the Engineer-in-charge.

Mixing shall be done by mechanical means only. The sequence of feeding of

the ingredients into the mixer shall generally be as under:

50% of requirement of water.

50% of the requirement of sand.

Full quantity of cement.

159


Balance quantity of sand

Balance quantity of water.

5.9.0 Mix Variation :

5.9.1 Mix Variation Clause For Cement :

lf the proportion of cement to sand is varied an addition or dedcution, shall

be made in the'rate of masonry at the schedule 'A' rate used in excess, or

short of stripulated requirements of cement per cubic metre of masonry.

For this purpose of the volume of mortar in masorny shall be taken 45%

volum'e of masonry and the volume of monar will be taken to be equal to the

volume of the sand before mixing.

joints as much as possible. They shall be solidly bedded in mortar with close

joints. No joints shall exceed 4 cm. not shall it be less than 12mm. in th

thickness. Chips of stones and spauls shall be edged into the work where

ever necessary, to avoid thickness orjoints of mortar and to give masonry of

maximum density.

No dry work or hollow speces shall be allowed. Every stone, whether large

or small, shall be set flush in mortar, shaken and hammered down by a

mallet to sink into it. The smaller stones used in the tilling shall be carefully

selected to fit snuggle into the interstices between the larger stones.

Mortar to be added to fill the intervening spaces shall be well worked out by

trowel and steel bar disturbing the mortar during the period of setting shall

be avoided. Mortar joints of top and sides of a layer shall be pressed and

brushed over by coir brush as soon as masonry is laid so as not to leave

any loose mortar.

160


5.10.5 (A) Bonding And Bond Stone

For ensuring good bond, masonry shall be finished uneven at the end of the

stone and create air pockets.

ii. Putting chips in the intervening space before filling with mortar shall

be avoided. _

iii Livelling of masonry on the top ofthe coarse by use of chips shall be

D avoided. All chips on ends will be driven on one end only, which will

help to squeeze compact mortar in the joints.

SECTION - 6

STEEL REINFORCEMENT

Scope of Work

6.1.0 This item shall include supplying bending and erecting in position steel rein-

forcement.

6.2.0 Reinforcement Bars

6.2.1 Steel reinforcement bars and fabrics shall be placed in the concrete as shown

in the Drawing or as directed. before Steel reinforcement is placed in

positionthe surface of the reinforcement shall be cleaned of rust, Scale, dirt

and grease and other objectionable foreign substances (heavy flaky rust

and Mill scale that can notremoved by Hrm rubbing with burlap, or equivalent

treatment is considered objectionable). The fact that light or early stage rust

has not determintal effect on bond and hence could be discharged shall not

be used as execuse of careless handling and storage of steel. In storing

bars ofthe same size, length shapes and grade shall be assembled in racks

and marked distrinctly. Before the reinforcement bars are Hxed in position it

shall be verified that they are of specific size and bent in accordance with

the plans and specifications. They shall be accurately placed and secured

in position by means of built in concrete block, metalic chairs, hangers,

spacers and other suitable devices at sufficiently close intervals, so that

they will not sag between supports, not be displacing of the concrete or by

any operation of the work.

6.2.2 Special care shall be exercised to prevent any disturbance of the

reinforcement in concrete that has already been placed.-The reinforcement

after being placed in position shall be maintained in a clean condition until it

is completely embedded in concrete to prevent further damage to the

concrete or unsightly rust stains on exposed concrete surface.

6.2.3 Reinforcement shall not be straingtendorbend in a mannerthat will injure or

weak the materials. Bars with kinks or bends not shown on the plans shall

not be used. Bars shall be bent to the shape and dimensions shown on the

drawing or as directed. Using a bars bender, operated by hand or power, to

attain the proper bending radious. The radious of bend shall not less than 4

times the nominal size of the bar. Heating of reinforcement bars to facilitate

bending will not normally be permitted when, however, such heating is

permitted in the case of large diameter bars, he temperature of the steel

shall not exceed the corresponding to a cherry red colour.

6.3.0 Binding

Wire of tying reinforcement shall be of soft and unsealed steel. The wire

may be of 1.22 mm. to 1.63 mm. and shall have to confirm to IS 280-1962.

Metal support and spacers shall be fabricated from non-corrodable metal.

Dissimilar metals shall not be placed in concrete in intimate proximity with

167


each other or be joined by a connector especially in the continued

presence of moisture unless it is known that galvanic action will not result.

6.4.0 Distance Between Reinforcement Bars

6.4.1 The distance between two parallel reinforcement bars shall be except as

provided below in 6.4.2. not less than greatest of the following distances _

a) The diameter of either bar, if their diameters be equal.

b) The diameter of the larger bar, if their diameters be unequal.

c) 6 mm. more then the nominal maximum size of the coarse

aggregate comprised in such concrete.

Note; A greater distance should be provided when convenient.

6.4.2The vertical distance between two hori;ontal main steel reinforcement or

the corresponding distance at right angles to two inclined main steel rein-

forcements shall be not less then 12 mm.. except-at a splice or lap and

except where one of such reinforcement is transverse to the other.

6.4.3The pitch of the main bars in a reinforced concrete solid shall be not more

than three times the effective depth of such slab, or 60 cm. whichever is

less.

6.5.0 Splicing

Bars splices as indicated in the drawing or as speciafied by the

Engineer-in-charge shall only be' allowed. The lapped ends shall be placed

toensure full bond on each bar. Splicing shall not be done in the region of

maximum bending moment, and splicing of adjacent bars shall be avoided

as far as possbile. '

Welding of bars for splicing may be allowed in place of lapping at the discre-

tion of the Engineer-in-charge at aproved locations. When welding is re-

sorted, instead of lapping, the bar to be spliced shall be lap welded or but

welded by electric are welding. Ends of bars to be spliced shall be cleaned

of all dirt. Sclaes, rust paint and foreign matter before welding. All welding

shall confirm to the relevant lndian Standard Specification. Any weld will be

considered un-satisfactory if it fails to sustain a tensile stress of at least

90% of the tensile stress of the bar in which the weld has been made. The

contractor shall make necessary arrangements, for carrying out the tests

as directed by the Engineer-in-charge and with the accepted unit rate for

reinforcement.

6.6.0 Cover

6.6.1 Sufficient concrete cover shall be provided to protect reinforcement from

corrosion or as indicated in the drawings. All protruding bars from

concrete or masonry to which other bars are to be spliced and which will be

exposed to action of weather for anindefinite period shall be protected from

rusting by a thin coat of neat cement grout.

168


6.6.2 The thickness of concrete cover (exclusive of plaster of other decorative

finish) shall be as follow.

a) At each end of reinforcing bar a cover not less than 25 mm. not less

than twice the daimeter of such rod or bar

b) For a longitudinal reinforcing bar in a column cover than 40 mm. nor

less than diameter of such rod or bar in the case of column of

minimum diamensions of 18 mm. or under those bars do not

exceed 12 mm. diamater, 25 mm. cover may be used.

c) For a longitudinal reinforcing bar in a beam a cover not less than 25

mm. not less than the diameter of such rod or bar.

d) for tensile, compressive shear or other reinforcement in a slab a

cover, not less than 12 mm. not less than the diameter of such rein-

forcement.

e) For all external work for work against earth faces and also for

intemal work where there exists particularly corrosive conditions. The

cover, of the concrete shall be increased by 12 mm. beyond the

figures given above (a to d).

6.6.3 Where because of splicing, the thickness of concrete in between reduces

to less than the maximum size of the aggregate a concrete with reduced

maximum size of aggregate shall be used as to allow development of bond

in the splice. The extra cost of such special concrete shall be deemed to

have been included in the unit rate for the main concrete and shall be paid at

the same rate.

6.7.0 Inspection before Concreting

No concreting shall be started unless the reinforcement as laid is finally

checked and certined by the Engineer-in-charge or his authorized rep-

resentative. Before starting the concreting the contractor shall make certain that the

measurements of the reinforcement placed in have been recorded and that the

Engineer-in-charge cortices the correctness of reinforcement used. Failure to do so may

mean no payment or payment at the

discretion of the Engineer-in-charge for the reinforcement concrete.

6.8.0 Anchor Bars

The cost of anchor bars proper shall be paid under the item of reinforcement.

6.9.0 Mode of Measurements

Accurate records shall be kept at all times of numbers, size, length andweight of bars

placed in position for different parts of the work. Thereinforcement shall be paid as the

weight of actual quantity of steel

169


reinforcement placed in the structure arrived at the time of measuring theactual length

of the bars used and placed as shwon in the bar bendingschedules including hooks,

bends, and laps. The length of the bar shall bemeasured to the next nearest 10 cm. a

fraction less than 5 cm. being neglected and fraction of 5 cm. more taken as 10 cm.

weight shall be computed from the standard table of weights.

6.9.1 The unit rate accepted forthe reinforcement shall include the cost of

suplying,cutting, bending, cleaningstraightening, fixing and maintaining in positionthe

reinforcement. Supplying and attaching binding wire, supports separators, hangers etc.

shall be deemed to be included in the unit rate for reinforcement

and shall not be measured nor paid where welding ispermitted, for splicing, shall not be

paid for separately. Chairs if any provided as per instruction of Engineer-in-charge will

be paid separately.

Surplus steel in pieces longer than 2.5 m. out of the steel issued to thecontractor will be

taken back at the rate at which it was issued to thecontractor. The conveyance to the

place of original issue of such steel beingat the contractor's cost. V
