Rate analysis: brickwork 1:4, 10 m³

Short answer

For 10 m³ 1:4 brickwork superstructure: bricks 5609 nos., cement 19.22 bags, sand 2.67 m³, mason 16 md, labourer 22 md. Direct cost Rs 147,108, plus 15% overhead/profit gives Rs 169,174.20, i.e. Rs 16,917.42 per m³, excluding VAT.

Prepare rate analysis for 10 m³ of brickwork in (1:4) cement sand mortar in superstructure. Take brick size: 230 × 110 × 55 mm and mortar joint thickness: 10 mm.

Mortar and brick quantities for 10 m³

Brick with mortar: 240×120×65240 \times 120 \times 65 mm (10 mm joints).

  • Number of bricks per m³ = 10.24×0.12×0.065=534.19\dfrac{1}{0.24 \times 0.12 \times 0.065} = 534.19; for 10 m³ = 5341.88 nos. (net). Add 5% breakage: 5609 nos.
  • Volume of bricks alone = 5341.88 x 0.23 x 0.11 x 0.055 = 7.433 m³.
  • Wet mortar = 10 - 7.433 = 2.567 m³.
  • Dry mortar = 2.567 x 1.30 = 3.337 m³ (1.30 allows for voids in sand and loss).
  • For 1:4: cement = 3.337/5 = 0.6674 m³ x 1,440 = 961.0 kg = 19.22 bags; sand = 3.337 x 4/5 = 2.669 m³.
