Note: Construction joints shall be at pre approved locations only shall
be vertical or stepped. Concrete shall be chipped immediately after final
setting using mechanical chippers and thoroughly cleaned. Surface shall
be given

The rates shall also include account for any admixtures (approved by the
consultants) the contractor may use in order to enhance the workability,
to achieve accelerated strength, etc. The rate shall include use of
plasticizers and retarders to limit the water/cement ratio to 0.45 and
the temperature to 25 degree C at the time of setting. Complete care
shall be taken to achieve dense and fully watertight concrete.

staging for casting floors of different heights, roof projections at various
levels and profiled formwork.
Contractors shall submit drawings showing the scheme of formwork
including back propping and proper sequence of removal of formwork
and back propping so that the structural slab will not be overloaded due
to construction loads.
Formwork shall be designed for close jointed rigid, durable and shall
have adequate strength, water tightness and ensure easy removal etc.,
Props, shoring and bracings shall be all in steel or Aluminium.
Formwork designed with proposed materials (to be approved prior to
making) shall be able to retain its shape, line, dimension, level within the
allowable limits of variations.

VI A) REINFORCING STEEL :
Providing & Fixing steel reinforcement for RCC including material,
fabricating as per IS-2502, transporting, storing, de-coiling,
straightening, cutting, bending, spirally hooping and placing in position
at all levels, including all labour, equipments, supplies, incidentals,
sampling and testing as prescribed in IS codes including all charges
thereon for requisite tests, supervision and binding with approved
quality binding wire. The measurement shall be as per IS 1200 Part- and
unit weight shall be derived as mentioned in IS 1786. The rolling margin
shall be on Contractors own cost. The rate shall include cost of cover
blocks, binding wire, chairs, spacers and pins to be provided as per
specifications and the same will not be measured separately for
payment. Quantity of steel as per drawing and with authorized overlaps
only shall be measured and paid for.
The quoted rate will include welding of reinforcement with low
hydrogen low heat welding electrodes for the welding length mentioned

only wherever consultants recommend, for which no extra shall be
claimed. Replacing conventional laps with welding splices will be
entirely at consultants discretion. Such unclaimed welding will also
include welding of reinforcement to already fixed insert plates,
structural steel members etc. Shear connectors prepared from the
reinforcing steel welded to structural steel members shall be measured
in the reinforcement item.
The rate also includes protecting the reinforcing bars in their virgin
form or in the fabricated form, or when placed and tied up position or
as dowels left for future continuation of work or at construction joint
against corrosion due to exposure to weather if left exposed and un-
encased for more than three weeks from the date of delivery to the site.
Cement wash shall be given to such bars if they are likely to be exposed
for more that three weeks and less than twelve weeks. Process of
application of cement slurry shall be repeated after every twelve weeks
