Concrete : 0.038
cum per sq. ft. of plan area. (+/- 5%)
Steel : 4.50
to 5.00 Kg per sq. ft.
Shuttering : 2.40
to 2.50 times the plan area of slab (this includes col./beams/sides etc)
Brick Work : 0.015
cum per sq. ft. of plan area.
Approximately 0.25 cubic metres of
mortar and 500 bricks are required for 1 cubic metre of brickwork
Concrete: 0.5A
Cum for Commercial Bldg.
0.2A Cum for Residential Bldg.
Where, A= Total Built Up Area.(i.e. Plinth
Area xNo. of Floor)
Steel: 4.5-4.75
kg per Sqft of Built up Area for Residential Building
5.0-5.5 kg per Sqft of Built up area for
Commercial Building.
Formwork: (1).
Shuttering = 6 times the quantity of concreting.(or2.4 times the plinth area)
(a) No of12 mm Ply (2.44mx1.22m)=0.22 times of
shuttering ( or, 0.4A)
(b)Batten(75mmx40mm)=19.82X No. of Ply
Sheets(it gives batten in RM)
(c)Nails=0.22x total area of shuttering.(unit-kg)
Practically, 75 gm nails and 75 gm binding wire + nut-bolts are consumed per
sqm of shuttering
(d)Shuttering Oil=0.065x total area of
shuttering(unit-Lt)
Electrical cost = Rs

If its only for slab ….then a 5″ slab almost
costs roughly Rs.220/- per sq. Feet all inclusive of Steel, Rcc, Shuttering
etc.
If you are asking for residential building
complete in all respects…than it costs u around Rs. 1200/- per sq. Feet. Civil
Structure Work – Rs. 750 per sqft and for Finishing Work – Rs. 450 per sqft.
(a) Painting - Rs 12 - 17 per
sqft (two layers of putty + two layers of coat) including taxes
(b) Flooring - Marble is Rs 80 per
sqft (depends on the type of marble may be - but this is what it is costing
us). Granite and bathroom tiles 15 - 20 Rs per sqft (we provide all material
such as cement, sand etc).
(c) Electrical - You are
better off buying the materials for them. A rough guide is Rs 50 - 100 per sqft
for materials and Rs 12 - 20 per sqft for labor.
