SECTION – III
SPECIAL SPECIFICATIONS FOR RCC WORKS
The work shall be carried out as per the relevant Indian Standard Codes (latest versions- List
enclosed)
In addition, following conditions are required to be followed;
a) To avoid settlement of centering, it is necessary to complete the compaction of the
murum filling under the floors, prior to erection of the form work for slabs and beams and
the box girders. It is preferably to complete the PCC under the floors before the formwork
is erected.
b) The surface of the form work likely to come in contact with the concrete, shall be treated
with sopa solution, mould oil or any other approved material so that concrete when laid,
will not stick to the form work; thereby facilitating easy removal of the forms.
The
treatment should be carried out sufficiently before laying of the reinforcement. The forms
should be watered prior to pouring of concrete.
Care should be taken to prevent
reinforcement coming in contact with any oily substance.
c) The steel shall be placed exactly in accordance with the drawings and instructions, and
shall be properly tied, to form a rigid grilliage which will not be disturbed during the
concreting operations. The splicing shall be kept to a minimum, the joints should be well
staggered and arranged, any given section a minimum of 2/3 rd of the bars should be
without laps. For splicing of bars of 8 mm dia and above approved type of welded joints
shall be used.
No ‘extra over’ shall be allowed for the welding.
Where concrete
dimensions are very small, hooks, in the directions of greater dimensions can be
provided.
d) Concrete shall not be cast unless the reinforcement as laid has been checked and
certified by Architects or their authorised representatives. Architects should be intimated
sufficiently in advance regarding the schedule of concreting certain part of the building so
as to allow them adequate time for making the necessary arrangements for checking of
the reinforcement, form work centering, etc., and also for supervising the actual
concreting operations.
e) Concrete shall be vibrated carefully until all the entrapped air is expelled. All members of
concrete shall first be vibrated by emersions vibrators and then, by surface vibratos
followed by manual ramming. Form vibration is compulsory for the concreting of the box
gird.
Bidder
Managing Director
66
BHOREMDEO SAHAKARI SHAKKAR UTPADAK KARKHANA MARYADIT
f) The shuttering for tower shell shall be by slip form method. To ensure proper compaction
of the concrete walls of tower shell form work vibration is required.
Therefore, the
formwork, should be rigid enough to sustain vibration without de – shaping of the same.
As such, the form work of the tower shell should be carefully designed and executed.
g) The contractor is advised to study the schedule of completion of the various components.
He should calculate the number of sets of form work required to keep pace with the
schedule.
h) Forms for pre – cast concrete shall be of either steel or 12 mm thick plywood neatly
made, strictly in accordance with the details submitted by the Architect.
i) Concrete mixed design: For concrete of grade below M15 and below nominal mixes may
be used. However, for concrete of M 20 and above the mix should be designed and
concreting operations should be of the ‘controlled type’.
Following minimum quantity of cement shall be used.

The design mix, which is on weight basis, may be converted in volumetric equivalents
for convenience. Use of weigh batcher is also permissible. The mix design will be obtained
from an approved laboratory at the cost of the Contractor.
j) Roughening of concrete surfaces should be done thoroughly, after stripping of the form
work so as to obtain proper key for plastering.
k) The contractor should include in his rates, the charges for fixing of metallic or other types
of inserts for fixing of electrical fitting and fixture, and piping or other service. These
inserts shall be fixed by the contractor as per the drawings and the instructions of the
Architect. The inserts will be provided by the owner free of cost of site.

PLASTERING
0.1 Cement Plaster:
Cement and fine screened sand shall be thoroughly mixed, dry in proportions specified.
Water shall then be added gradually and the mortar mixed thoroughly until it is
homogenous in appearance and uniform in colour and of the required consistency. No
more mortar shall be prepared than can be used up in 20 minutes. The joints of the
masonry shall have been raked to a depth of 15 mm. The surfaces to be plastered shall
be thoroughly washed and drenched with water plaster then applied, and worked evenly
to the specified thickness by means of long straight edges.
The surfaces finished shall be as specified.
Ordinary finished may be done with
wooden floats or steel trowels as directed, in which case, the surface is rubbed over
until it is even and smooth.
When neeru finish is specified, the surface will be rendered even with long wooden
straight edges without trowelling before the neeru is applied.
Neeru shall then be
applied, as soon as possible, to avoid surface cracking, and rubbed over to an even
smooth surface first by wooden straight edges and then thoroughly by steel trowels,
‘Neeru’ shall be applied finally and rubbed down sufficiently to make the surface even
and smooth and shall be as specified in 05. the plaster shall be kept constantly wet for
about 15 days. All corners and angles shall be perfectly plumb and true and soffits or
arches shall be true to shape.
All jambs and reveals shall be carefully finished at the door and window frames. All
lines shall be true and straight and levels correctly maintained. Internal angles shall be
rounded, if so directed and all edges shall be rounded, splied or beaded as directed
without extra charges.
The measurements shall be in units of square meters, openings being deducted. A
jamb reveals, sills and soffits at openings will be measured paid for.
All cornices, mouldings etc., shall be formed in the masonry and / or concrete work and
finished with plaster as per details and instruction. Nailed cornices will not be permitted.
Ceiling mouldings projecting less than 18 mm thick may, however, be permitted to be
formed in plaster only.
