Prepare an approximate estimate of cost for (G+2) RCC framed structure building there are four flats on each floor and having carpet area of 1200 sqft each. Consider cost of construction of superstructure =Rs. 850/sqft. Assume other required data.

Carpet area $\text{= Carpet area/flat1} = 1200 sqft \\ \text{= Carpet area /floor} = 1200*3 \\ = 3600m²$

Total carpet are $= 3600* 3 \\ = 1080$

Total built up area $= 10800+\dfrac{10}{100} * 10800 + \dfrac{15}{100} * 10800 \\ = 13500$

Cost of superstructure $= 850/ sqft \\ = 13500*850 \\ = 11475000$

Cost of foundation $= \dfrac{20}{100} * 11475000 \\ = 2295000$

B.C. = 13770000

Cost of WC $= \dfrac{5}{100} * 13770000 \\ = 688500$

Cost of sanitation $=\dfrac{5}{100} * 13770000 \\ = 688500$

Cost of electrification $= \dfrac{7}{100} * 13770000 \\ = 963900$

Overall cost = 16110900

Contingency $= \dfrac{5}{100} * 16110900 \\ = 805545$

Work charged establishment $= \dfrac{2.5}{100} * 16110900 \\ = 402772.5$

Final cost = 17319217.5
