Rate analysis: brickwork 1:6 per m³

Short answer

For 1 m³ 1:6 brickwork in upper floor, use 561 bricks, 1.37 bags cement, 0.286 m³ sand, 2 masons, 3 helpers and scaffolding allowance. Sub-total Rs 15,963 plus 15% overhead gives Rs 18,357.45 per m³.

Prepare an analysis of rate for 1st class brick work in (1:6) cement mortar (in upper floor) per m³.

Basis

Rate per m³ of 1st class brickwork in 1:6 cement-sand mortar in the upper floor, standard brick 230 x 110 x 55 mm with 10 mm joints (nominal size 240 x 120 x 65 mm). All rates are illustrative.

Materials per m³

  • Bricks (net) = 10.24×0.12×0.065=534.19\dfrac{1}{0.24 \times 0.12 \times 0.065} = 534.19 nos.; with 5% breakage = 561 nos.
  • Volume of bricks without mortar = 534.19 x 0.23 x 0.11 x 0.055 = 0.7433 m³, so wet mortar = 1 - 0.7433 = 0.2567 m³.
  • Dry mortar = 0.2567 x 1.30 = 0.3337 m³ (30% for filling voids and shrinkage).
  • Cement = 0.3337/7 = 0.0477 m³ x 1,440 kg/m³ = 68.6 kg = 1.37 bags.
  • Sand = 0.3337 x 6/7 = 0.286 m³.

Answer: Rate of 1:6 brickwork in the upper floor = Rs 18,357.45 per m³ (excluding VAT). The extra labour and scaffolding for the upper floor is the difference from the ground-floor rate.
