How much steel is required for 1200 sq ft house, hi guys in this article we know about quantity of steel is required for 1200 square feet house. Actual Steel calculation is based on as per design but if design is not given then Steel calculation is based on Thumb Rule on experience basis.

How much is steel is required for 1200 sq ft house is based on different type of criteria

1) type of structure (Load Bearing/Framed)

2) Purpose of structure (Load depends on the utility)

3) Type of dia of Bar

4) Size height of column and length of beam (in terms of height, as requirement varies according to construction i.e. whether horizontal or vertical. )

5) Most important is foundation type(depends on soil bearing conditions)

For general residential building of ground floor house we have to calculate Steel quantity. We use different types of Thumb Rule for steel calculation all type of RCC structure footing, column, beam & RCC slab.

**How much steel is required for 1200 sq ft house**

Now taking various Thumb Rule for Steel quantity calculation for 1200 square feet house

1) thumb rule for steel in rcc slab is 80 kg/cubic meter of wet volume of concrete

2) thumb rule for steel in beam is 120 kg/cubic meter of wet volume of concrete

3) thumb rule for steel in column is 160 kg/cubic meter of wet volume of concrete

4) thumb rule for steel in footing is 40 kg/cubic meter of wet volume of concrete

5) thumb rule for steel in rcc structure is 120 kg/cubic meter of all calculated wet volume of concrete.

6) thumb rule for steel in rcc structure is 3.5 Kg to 4 kg/ sq ft of built up area.

If we take last thumb rule point (6), thumb rule for steel in rcc structure is 3.5 Kg to 4 kg/ sq ft of built up area**.**

**💐— WATCH THIS VIDEO—💐**

If built area is 1000 sq ft house we require steel quantity

= 3.5 × 1000 = 3500 Kg

= 4 × 1000 = 4000 kg

3500 Kg to 4000 Kg of Steel quantity is required for construction of 1000 square feet house.

If built area is 1500 sq ft house, we require steel quantity

= 3.5 × 1500 = 5250 Kg

= 4 × 1500 = 6000 kg

52500 Kg to 6000 Kg of Steel quantity is required for construction of 1500 square feet house.

**How much steel is required for 1200 square feet house ground floor?**

For the construction of residential building of ground floor we have RCC structure like footing, column, beam and slab. Taking one rough design of 1200 square feet house having different dimension of rcc structure like footing, column, beam and slab are following:

1) footing size = 1500 mm × 1500mm × 300 mm

Length of footing = 1500 mm

Width of footing = 1500 mm

Height of footing = 300 mm

Depth of earth exacavation = 1500 mm

Concrete size in footing = 1200mm×1200mm×300mm

No of footing = 12

Wet volume of concrete in all 12 no of footing = 1.2 m × 1.2 m × 0.3 m × 12 = 5.184 m3

**thumb rule for steel in footing is 40 kg/cubic meter of wet volume of concrete**

Steel quantity = 5.184 × 40 = 208 Kg

208 Kg of Steel required in footing RCC structure of 1200 square feet of house

2) column size = 300 mm × 400 mm

No of column = 12

Height above dpc = 3000 mm

Height above rcc slab = 900 mm

Depth of earth exacavation = 1500 mm

Total height of column = 5400 mm

Wet volume of concrete for all 12 column

= 0.3 × 0.4× 5.4 × 12 = 7.78 m3

thumb rule for steel in column is 160 kg/cubic meter of wet volume of concrete

Steel quantity = 7.78 × 160 = 1244 kg

1244 Kg of Steel required in column RCC structure of 1500 square feet of house.

3) plinth beam size = 300mm × 300 mm

Width of beam = 300 mm

Depth of beam = 300 mm

Overall length of all beam = 240 ft = 72000 mm

Wet volume of concrete = 0.3 × 0.3 × 72 = 6.48 m3

thumb rule for steel in beam is 120 kg/cubic meter of wet volume of concrete

Steel quantity = 6.48 × 120 = 778 kg

778 Kg of Steel required in plinth beam RCC structure of 1200 square feet of house.

4) door beam size for external wall = 225mm × 150 mm

Overall length for external beam = 140 ft = 42000 mm

Steel = 0.225 × 0.15 × 42 × 120 = 170 Kg

Door beam size for internal wall = 125 mm × 150 mm

Overall length for internal beam = 100 ft = 30000 mm

Steel = 0.125 × 0.15 × 30 × 120 = 67.5 Kg

Steel for door beam = 170 + 67.5 = 237.5 kg

237.5 Kg of Steel required in door beam of 1200 square feet of house

5) roof wall beam size for external wall = 225 mm × 200 mm

Overall length for external beam = 140 ft = 42000 mm

Steel = 0.225 × 0.2 × 42 × 120 = 227 Kg

Roof wall beam size for internal wall = 125 mm × 200 mm

Overall length for internal wall beam = 100 ft = 30000 mm

Steel = 0.125 × 0.2 × 30 × 120 = 90 Kg

Steel for roof beam = 227 + 90 = 317 kg

317 Kg of Steel required in roof wall beam of 1200 square feet of house

6) rcc roof slab = 40′ × 30’×6″

Length of slab = 40 feet

Width of slab = 30 feet

Thickness of slab = 6 inch = 0.5 feet

Volume = 40′ × 30’× 0.5′ = 600 cubic feet

1 m3 = 35.3147 cu ft

Volume = 600/35.3147 = 16.99 m3

thumb rule for steel in rcc slab is 80 kg/cubic meter of wet volume of concrete

Steel = 16.99 × 80 = 1359 Kg

1359 Kg of Steel required in rcc roof slab of 1200 square feet of house

Now Total weight of Steel required for 1200 square feet house

Footing = 208 kg

Column = 1244 kg

Plinth beam = 778 kg

Door beam = 237.5 kg

Roof beam = 317 kg

Roof slab = 1359 kg

Total weight of steel = 4143 Kg

Suppose 200 kg steel used in chhajjas, stair, septic tank & other rcc structure

Than total weight of steel = 4143 + 200 = 4343 kg

According to Thumb Rule 5% + (plus) or 5% _ (minus)

5% of 4343 = 217 Kg

4343 Kg of steel ( 208 kg in footing, 1244 kg in column, 778 kg in plinth beam, 237 kg in door beam, 317 kg in roof beam, 200 kg in chhajjas & 1359 Kg in rcc roof slab) is required for construction of residential building of ground floor of 1200 square feet house. This is a general guidelines and actual quantity may vary for special design, thanks.
