Work out the quantities of following items from given plan& section

1. 12mm thick internal plastering in CM 1:4
2. Brickwork (CM 1:6) in superstructure of ground floor
3. Concrete in footing
4. Flooring & Skirting

$\text{Trapezoidal portion} \\ V= \bigg(\dfrac{A1+A2}{2}\bigg) *H \\ = \bigg(\dfrac{0.38*0.38+1.2*1.27*0.4}{2}\bigg) \\ = 0.333 m²$ $\hspace{5cm}$ $\text{Trapezoidal portion} \\ V= \bigg(\dfrac{A1+A2}{2}\bigg) *H \\ = \bigg(\dfrac{0.38*0.48+1.2*1.37*0.5}{2}\bigg) \\ = 0.456 m²$

$\text{Rectangular portion} \\ = 1.2*1.27*0.15 \\ = 0.22 m³ \\ VF1 = 0.333+0.22 \\ = 0.553 m³$ $\hspace{7.5cm}$ $\text{Rectangular portion} \\ = 1.2*1.37*0.15 \\ = 0.246 m³ \\ VF2 = 0.456 + 0.246 \\ = 0.702 m³$

Step 1:-

Total cl $= 3.46*6+2.48*3+2.73*5+2.6+2.63*2+2.78*2+1.8+1.23*2+4.23*2+4.98+2.3*2 \\ = 77.57$

No of junction = 12

Step 2:-

Prepare an abstract sheet for above question
