Content of Lecture # 5

Example #1: Estimate of R.C.C Slab

Example #2: Estimate of R.C.C Beam

R.C.C Work & Structures

Reinforced Cement Concrete work is usually estimated under 2 items.

1.The concrete work including centering & shuttering & binding of steel bars in position is taken under one item in m3 .

2.The steel reinforcement & its bending is taken under a separate item in quintals (cwt) or Kg or tones.

The quantity of steel being small, no deduction is made for steel from the volume of concrete.

Binding wire is not taken separately, but wp-wp-includessd in item of R.C.C work.
