Slabs, beams and similar members shall be poured in one operation, unless
otherwise instructed by the Engineer. Moulding, throating, drip course, etc.,
shall be poured as shown on the drawings or as directed by the Engineer.
Holes shall be provided and bolts, sleeves, anchors, fastenings or other
fixtures shall be embedded in concrete as shown on the drawings or as
directed by the Engineer. Any deviation therefrom shall be set right by the
Contractor as instructed by the Engineer.
In case the forms or supports get displaced during or immediately after
the placement and bring the concrete surface out of alignment beyond
tolerance limits, the Engineer may direct to remove the portion and
reconstruct or repair the same.
The Engineer shall decide upon the time interval between two placements of
concrete of different ages coming in contact with each other, taking in
consideration the degree of maturity of the older concrete, shrinkage,
heat dissipation and the ability of the older concrete to withstand the load
imposed upon it by the fresh placement.
Once the concrete is deposited, consolidated and finished in its final
position, it shall not be distributed.
3.13 Construction Joints and Cold Joints
3.13.1 Construction Joints
It is always desirable to complete any concrete structure by continuous
pouring in one operation. However, due to practical limitation of methods
and equipment and certain design considerations, construction joints
are formed by discontinuing concrete at certain predetermined stages. These
joints will be formed in a manner specified in the drawings/ Instruction.
Vertical construction joints will be made with rigid stop-board forms having
slots for allowing passage of reinforcement rods and any other
embedments and fixtures that may be shown. Next stage concrete shall be
placed against construction joint as per clause 3.12. For water retaining
structures and leak-proof buildings suitable approved water bars will be
installed at the construction joints.
