Cost per flat, Rs	9825	12872	15919	18966

Note:

Construction period is calculated as follows:

Average 22 pouring of concrete are considered per month.

About 3 months are required for mobilization and getting plinths ready.

About 3 months are required for finishing.

Cost of formwork = $ 360; dollar Exchange Rate = Rs50; No of flats = 1120

(Weight of aluminium formwork = 24 kg/m²).
