Rate analysis: 40 mm PCC 1:2:4 floor

Short answer

Per m² of 40 mm PCC (1:2:4): cement 0.253 bag, sand 0.0176 m³, aggregate 0.0352 m³; mason 0.08 day, unskilled 0.20 day; total rate NPR 1,022.50 (direct cost NPR 818.00 plus overhead and profit).

Prepare an analysis of rate for 40 mm thick PCC (1:2:4) in floor per m².

Rates and labour norms below are illustrative (DUDBC-style norms; use the current District Rate and norms of the project area for a real estimate): cement NPR 1,000/bag, sand NPR 3,500/m³, 20 mm aggregate NPR 4,500/m³, skilled labour NPR 1,500/day, unskilled labour NPR 1,100/day, water lump sum, contractor's overhead 15% and profit 10% on direct cost (VAT excluded).

Quantities per m² of 40 mm PCC (1:2:4)

  • Wet volume =1×1×0.04=0.04= 1 \times 1 \times 0.04 = 0.04 m³; dry volume =1.54×0.04=0.0616= 1.54 \times 0.04 = 0.0616 m³
  • Cement =1/7×0.0616=0.00880= 1/7 \times 0.0616 = 0.00880 m³ =0.253= 0.253 bags
  • Sand =2/7×0.0616=0.0176= 2/7 \times 0.0616 = 0.0176 m³; aggregate =4/7×0.0616=0.0352= 4/7 \times 0.0616 = 0.0352 m³
  • Labour for mixing, laying, compacting, levelling and curing: mason 0.08 day, labourer 0.20 day per m² (assumed norm).
