Rate analysis: plain cement concrete (1:3:4)

Short answer

For 1 m³ PCC 1:3:4, dry volume 1.54 m³ gives cement 5.544 bags, sand 0.5775 m³, aggregate 0.77 m³. Labour: 1 skilled and 6 unskilled days. With 15% overhead and 10% profit, rate is NPR 23,975.32 per m³.

Prepare rate analysis of plain cement concrete (1:3:4). Assume suitable rates of material and labor.

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 m³ of PCC (1:3:4)

  • Dry volume =1.54= 1.54 m³; sum of ratio =8= 8
  • Cement =1/8×1.54=0.1925= 1/8 \times 1.54 = 0.1925 m³ =5.544= 5.544 bags
  • Sand =3/8×1.54=0.5775= 3/8 \times 1.54 = 0.5775 m³
  • Aggregate =4/8×1.54=0.7700= 4/8 \times 1.54 = 0.7700 m³
  • Labour: 1.0 skilled and 6.0 unskilled days per m³ for mixing, placing, compacting and curing (assumed norm).
