I believe minimum construction cost for a finished Plaza that you should keep in mind is Rs.1800/- per sq ft. This would include a plain face lift without using any fancy facelift touch to your plaza.
Updated material costs are:
Steel Bar 40G = 74000-75000 (plus delivery)
Steel Bar 60G = 81000-84000 (plus delivery)
Cement Fecto =415 per bag (plus delivery)
Bricks = 7500 - 8500 per thousand (plus delivery) good quality
Blocks 8x8x16 hollow = 28 (plus delivery) good quality
Note : these rates are subject to the change in market.
Never purchase Steel Bar from thiya or vendors on road as you will never get full weight of steel that you paid for eventually ending up purchasing more and increasing your cost of construction.
If you need any other assistance, please feel free to ask.
