added to concrete during pouring. 28 It often happens that during long pour, while concrete truck getting delayed, concrete

stuff is stiffened causing hardship to workers. 29 To avoid that stiff state of concrete mix, they tend to add water to mix, which is not

acceptable in any case.30 Start curing after few hours, depending on temperature, but sides of forms externally

can be kept cold by spraying water.31 Side forms can be removed after 24 hours to 36 hours, but it takes considerable time,

while opening forms due to many reasons.

delayed, which requires keeping exterior surfaces wet with water spraying.32 Immediately, after striking forms, urgent inspection has to be done for identification

of defects & for resorting to non compliance reporting as well as, obtaining recommendation of remedial actions.

33 Curing has to be effectively continued, first by applying curing compound on wet RCC surface using either water based compound or wax based compound as approved on project.

sets to certain extent, but does not form cold joints.28 Pour other layers over previous until 2m height/depth is reached & then allow, say

another half an hour for resting.29 Continue whole height pouring, following specified sequences & start curing initially,

as explained previously.30 Make sure that top of concrete wall is roughened for making construction joint.31 All walls outside forms have to be kept wet & top portion covered with polythene or

wet soaked hessian.32 Check external forms as well as, internal forms by strong hammer impact to find in

case, some voids do exist during application of vibrator.33 Make sure that repetition of forms would not be required soon. which means that

there would be no earliest requirement to strike forms in specified duration.34 In case of such non early requirement of striking, do not allow removal of forms, after

48 hours, but keep curing intact from top as well as, from outside.35 Allow removal of forms, when it is to be repeated for higher level.36 During monitoring of forms, make sure that lines do not go out of tolerance limits &

if so happens, try to reinstate by tightening supports.37 After striking forms, make sure that defects are identified for raising non compliance

vibrator is to be applied.20 In case of single waist pour, a stop end has to be fixed at possible lower level of upper

flight.21 Landing has to be poured as small slab along with its down stand or up stand beam, as

case may be.22 Finish on vibrated surface has to be applied in such a fashion that a rough surface is

available to receive floor finishes.23 Immediately, after pouring is over, curing has to commence with.24 For case of complete pouring with slab, work of pouring has to continue as explained.25 Stair forms shall remain in position, until all forms of slabs are struck with exception

of vertical sides of waist slabs, which can be removed post concrete 24/48 hours.26 Curing shall be considered an important activity, as it is difficult to stagnate or pound

a common practice.26 All onsite tests must be conducted, before receiving concrete trucks leave test

location for reaching pump location for concrete delivery.27 Quality engineer has to conduct all onsite tests & collect cube samples.28 All substandard/defective concrete truck loads would be sent back after rejection, but

it rarely happens.29 Since, pouring slab is a fast activity, intense supervision & controls are required to be

implemented in all respects.30 Some sort of medical arrangement could be made to meet an/all accidental

contingency.31 Drinking waters or cold liquids for consumption must be made available on location

for concrete crew/gang to drink to avoid both dehydration & sun stroke.32 For food time or tea time, a few minutes break would require standby crew/gang

replacement that must be made available on site.33 For workers passive moments, replacement should be made available.34 Beams have to be poured first, but not full depth.35 Concrete should not be poured into beams directly, but received on slab edges to

avoid impact on beams side forms to avoid opening or dislocation of forms.36 Concreting should start from one end & progress gradually, completing first stage

beams pour.37 Second stage should give concrete its level in right profile including slab portion.38 If temperature is high, immediate protection of surface has to be taken care of.39 In case of two pumps or three pumps are installed, concrete can be started from as

many locations as available number of pumps, but no cold joints are allowed.

ITPs Inspection & Test Plans1 Foregoing descriptions do provide to understand to some extent various quality

controls procedures in form of check list. 2 Check lists have been to some extent explained for young engineers. 3 In field, experienced engineers produce such list point wise, which are approved, after

incorporating required points of inspections.4 ITPs would be required for final check up/examination respecting all items essential

for inspections & approvals. 5 These plans shall carry relevant tests & inspections, rows or columns depending on

defined or included activities.6 These plans shall also, contain ‘hold’ & ‘release points’ as well as, test checks &

surveillance points. 7 All activities shall be dealt in accordingly.8 These ITPs definitions of requirements shall also, be projected on construction

method statements in part of QA.

Number of ITPs1 It is big issue to decide how many inspections should be planned for a project?2 Based on experience & works’ interests, it has been noticed that excessive inspections

do not cater for good quality requirement controls.3 Inspections should be conducted in a proposing manner by construction site

personnel.4 Inspections should be conducted in a decisive manner by construction quality

personnel.

Quality Assurance Requirements5 Inspections should be conducted in a supervising manner by consulting quality

personnel.6 Inspections should be conducted in a surveillance manner by consulting quality

personnel.7 All relevant personnel must be given procedural opportunities to share responsibilities

at various levels.8 It may not be necessary to create hundreds of work items for thorough technical

inspections, when all method statements have been approved.9 Excessive scheme for inspections may allow hold points that would jeopardize

progress on works, while simultaneously certain minimum level of inspections may jeopardize work qualities.

10 Moderation must be calculated to keep inspections in such an optimum style, that least paperwork is required with maximum level of quality achievement.

11 Work input should build a degree of confidence in construction personnel, while engineer end must enjoy trust over all personnel involved with project.

12 ITPs should be approved & sequenced in such a way, that progress shall move smoothly with minimum hold points, while surveillance should keep overall inspection eyes.
