WHAT IS BUILT UP AREA, CARPET AREA, SUPER BUILTUP AREA?

TOWER  

FLAT  NOS. AS PER SALE PLAN

UNIT TYPE

CARPET AREA INCLUDING 
BALCONY/SITOUT

BUILT UP AREA INCL. BALCONY/SITOUT

TERRACES BUILT UP AREA

TOTAL BUILT UP AREA INCL. BALCONY (A)

COMMON AREA (B) (% OF A)

SHARED COMMON AREA ( C ) ( % OF A)

TOTAL SBA D = (A+B+C)

CARPET AREA PER UNIT (E)

EFFICIENCY = (E/D)X100

Carpet Area is the area enclosed within the walls, actual area to lay the carpet. 

This area does not include the thickness of the inner walls. It is the actual used area of an apartment/office unit/showroom etc. 

•Built up Area is the carpet area plus the thickness of outer walls and the balcony. 

•Super Built Up Area is the built up area plus proportionate area of common areas such as the lobby, lifts shaft, stairs, etc. 

The plinth area along with a share of all common areas proportionately divided amongst all unit owners makes up the Super Built-up area. Sometimes it may also include the common areas such, 
swimming pool, garden, clubhouse, etc. This term is therefore only applicable in the case of multi-dwelling units.
-------------------------------------------------------------------------------------------------------------------
carpet area is the actual usable area which the user gets to use. Built-up area consists of area outside your house, staircase, elevator, etc which can constitute upto 25% of the area.

Example: if you buy a 1000 sq.ft built-up area, you will actually get to use only 750 sq.ft.

Super built-up is area for the parapet, podium, garden,etc, all of which is charged at market price and can constitute upto 40% of the area.

It is ILLEGAL to sell property at anything other than carpet area because while 
developing the land, the developer is not charged FSI for the built-up area, garden, 
parking space,etc. So if anyone is charging you for anything other than carpet area you have a right to complain to a redressal forum like consumer protection.

1. Carpet area - The actual area you use. The area on which ‘you can put a carpet’.

2. Built up area - Carpet area + area of walls and ducts. Around 10% more than the carpet area. A terrace is considered as half the actual area for calculating built up area. 

Some projects charge dry terrace same as internal rooms.

3. Super built up / Saleable area - Built up area + markup for common spaces like lifts and stairs. Usually 25% more than the built up area.

Residential Building Cost by Thumb Rule (Rate Per Square feet)

RESIDENTIAL RCC BUILDING COST BY THUMB RULE


Thumb rule to calculate the Steel quantity required for Slab, Beams, Footings & Columns:

For Residential buildings 4.5Kgs-4.75Kgs /SFT

For Commercial buildings 5.0Kgs-5.50Kgs/SFT


For more accurate results you can also use BN Datta recommendations:

As per B N Datta, the Steel quantity used in different members of the building can be calculated easily using the following recommendations.

Structural Member Percentage of Steel
Slab: 1% of the total volume of concrete
Beam: 2% of the total volume of concrete
Column: 2.5% of the total volume of concrete
Footings: 0.8% of the total volume of concrete

Example:

Thumb rule to calculate Steel quantity of above slab = Volume of Concrete x Density of Steel x % of Steel of Member

Steel quantity required for above slab = 3 x 7850 x 0.01 = 235Kgs


Thumb rule to calculate the Shuttering area:

Shuttering costs 15-18% of the total construction of the building. 
Shuttering is framed to bring the concrete in Shape. 
The Thumb rule to calculate the shuttering required is 6 times the quantity of concrete or 2.4 times of Plinth area.

Suppose, the concrete quantity is 0.5m3
then the shuttering area required is 0.5 x 6 = 3m2

Components of Shuttering:-
Shuttering Ply, Battens, Nails are components of Shuttering.

Shuttering Ply Quantity calculation:

The shuttering Ply has a length, width & depth of 2.44 x 1.22 x 0.012

The No. of Shuttering Ply sheets = 0.22 times of Shuttering

Suppose, the area of shuttering required = 3m

Then the Shuttering Ply required = 0.22 x 3 = 0.66m2

Battens Quantity Calculation:

Shuttering batten usually have a length & width of 75mm x 40mm.

Batten Quantity = 19.82 x No. of Ply Sheets

if the construction requires 25 Ply sheets, 
the total quantity of Battens are 19.82 x 25 = 495 Battens

Nails & Binding Wire Quantity in Shuttering:

75gms of Nails are used for 1m2 of Shuttering

75gms of Binding wire is consumed for every 1m2 of Shuttering.

Thumb rule for Shuttering oil Quantity:
Shuttering oil is used to de-frame or de-assemble from the concrete easily.

Total required Shuttering oil is = 0.065 x Total Area of Shuttering
(or) For every 15Sqm of shuttering 1 liter of shuttering oil is consumed.


Example :
15m2 is total area of shuttering, then Shuttering oil required = 0.065 x 15 = 0.975 lts

For Accurate Shuttering Area Calculation, You can check here Shuttering area required for slabs, columns, Beams, Footings

Thumb rule for Cement, Sand, Coarse Aggregate Quantity in Different grades of Concrete :

Concrete Mix    Cement Quantity   Coarse Aggregate Quantity  Fine Aggregate Quantity
M5 (1:5:10)           2.82 Bags                        0.98m3                                0.49m3
M7.5(1:4:8)           3.48 Bags                        0.97m3                                0.48m3
M10(1:3:6)            4.50 Bags                        0.90m3                                0.45m3
M15(1:2:4)            6.60 Bags                        0.88m3                                0.44m3
M20(1:1.5:3)        8.40 Bags                        0.84m3                                0.42m3

For Accurate calculation refer to Concrete Mix design for Different grades of concrete
