Short answer
Assuming a 4.0 × 3.5 m clear room with 230 mm walls: PCC in foundation 2.87 m³, brickwork in foundation and plinth 6.22 m³, salwood door/window frames 0.111 m³, and M20 RCC slab including projection 3.26 m³.
Estimate the quantity of the following items of work from the accompanying building drawings: i) PCC (1:3:6) in foundation ii) Brick work in (1:6) cement mortar in foundation and plinth. iii) Salwood work for doors and windows frame iv) PCC M20 for R.C.C. slab [Drawing not included in the scanned paper]
No drawing is given. Assumed: room 4.0 m × 3.5 m clear, 230 mm walls, centre-line length 15.92 m; trench 0.90 m wide × 1.00 m deep; PCC 200 mm; brick steps 0.69 and 0.46 m wide (150 mm each); plinth 0.45 m above GL; door 1.0 × 2.1, two windows 1.2 × 1.2; frames 100 × 75 mm sal; RCC slab 125 mm thick with 0.45 m projection all round (M20).
i) PCC (1:3:6) in foundation
| Item | No. | L (m) | B (m) | H/D (m) | Qty (m³) |
|---|---|---|---|---|---|
| PCC 1:3:6 under walls 0.90 × 0.20 | 1 | 15.920 | 0.900 | 0.200 | 2.866 |
| Total | 2.866 |
ii) Brickwork (1:6) in foundation and plinth
Wall height from the last step = 0.95 m.
| Item | No. | L (m) | B (m) | H/D (m) | Qty (m³) |
|---|---|---|---|---|---|
| Brick footing step 1 (0.69 m wide) | 1 | 15.920 | 0.690 | 0.150 | 1.648 |
| Brick footing step 2 (0.46 m wide) | 1 | 15.920 | 0.460 | 0.150 | 1.098 |
| Wall up to plinth | 1 | 15.920 | 0.230 | 0.950 | 3.479 |
| Total | 6.225 |
iii) Sal wood for door and window frames
| Frame | No. | L (m) | B (m) | H/D (m) | Qty (m³) |
|---|---|---|---|---|---|
| Door frame D (2×2.1 + 1.0) | 1 | 5.200 | 0.100 | 0.075 | 0.0390 |
| Window frame W (2×1.2 + 2×1.2) | 2 | 4.800 | 0.100 | 0.075 | 0.0720 |
| Total | 0.1110 |
iv) PCC M20 for RCC slab
| Item | No. | L (m) | B (m) | H/D (m) | Qty (m³) |
|---|---|---|---|---|---|
| RCC slab 125 mm incl. 0.45 m projection: (4.0+0.46+0.90) × (3.5+0.46+0.90) | 1 | 5.360 | 4.860 | 0.125 | 3.256 |
| Total | 3.256 |
(Lintels, beams and reinforcement are measured separately.)
