How To Calculate Covered Area In Construction?

How To Calculate Covered Area In Construction
How to measure covered area of a house? – Wall to wall dimension of the entire flat is considered to be a covered area. It encompasses the interior walls and the carpet area. You can determine this by adding together 12–15% of the carpet area. You may want to think about the top end, or 15% if the wall is particularly thick.

What is the covered area?

Covered area: It is the actual area under the roof +walls, pillars & balconies. It is approximately 8 – 10% more than the carpet area.

What is difference between plot area and covered area?

The built-up area, also called the Plinth area, is the total area provided for use. The Super built-up area includes common spaces like the park, playgrounds, gym, and other utilities common to the residents. The plot area is the land area between the fencing.

Is Covered area same as plinth area?

Difference Between Plinth Area and Covered Area – Covered area: The actual area under the roof plus the walls, pillars, and balconies. It is approximately 8 to 10% more than the carpet area. Plinth area: It is the covered built-up area measured at the floor level of any storey or the floor level of the basement of a building and is approximately 10 to 20% more than the carpet area.

How do I calculate roof covering area?

Calculating the Area (True) – If you want to get the exact area measurement for your roof, you can follow these steps:

Once you have your roof’s pitch, divide the number by 12. (For example, if your roof’s pitch is 4 in 12, you would divide 4 by 12. This would yield 1/3.) Next, square your result. (If your number is 1/3, squared would yield 1/9.) After that, add 1 to your number. (1/9 + 1 = 10/9.) Next, figure out the square root of your new number. (The square root of 10/9 is 1.05.) Next, use your measuring tape to measure the length of your house. (Be sure to include overhangs.) After that, measure the width of your house. (Be sure to include overhangs.) Multiply your house length by your house width to get the area. (For example, 40 feet x 30 feet = 1,200 square feet.) Next, multiply the area by your roof’s pitch. (1,200 x 1.05 = 1,260 square feet.) To allow for hips, ridges, and waste, add 10% of your final number for a gable roof and 17% of your final number for a cottage roof. (Your total number would be either 1,386 or 1,474 square feet.)

What is carpet area, built-up area and super built-up area? | ICICI Blogs Property area is commonly calculated in square feet or square meters. While buying a house you may come across terms, such as carpet area, built-up area and super built-up area.

These terms may confuse you as a buyer and many assume all these are inter-changeable. Although they may sound similar, there is a lot of difference in what actually constitutes the carpet area and built-up area. Carpet area: The area in the flat or the apartment, which you could cover using a carpet, is the carpet area.

Also known as the net usable area, the carpet area is actually that space in your home, which can be used for laying a carpet. It includes the thickness of the internal wall but excludes the balcony or terrace. Technically, the distance between the inner walls is the carpet area.

  • As per RERA, the net usable floor area of an apartment excludes the area covered by the external walls, areas under services shafts, the balcony or verandah and any open terrace area, but includes the area covered by the internal partition walls of the apartment.
  • Carpet area calculation:
  • Carpet area = Area of bedroom + living room + balconies + toilets – the thickness of the inner walls.

In most cases, the carpet area in your flat would typically be 70% of its built-up area. So, if the built-up area of a property is 1,500 sq. ft., its carpet area would typically be 1,050 sq. ft. Importance of carpet area: The area calculation and the space that you would have, in exchange for the price you pay for purchasing the property, is critical.

As is obvious, the larger the space, the higher the cost. Similarly, the smaller the space, the lower the cost. Under RERA, builders are now legally obliged to mention the carpet area to measure price units. Provisions have also been made for the increase and decrease in its measurement, while developing an under-construction project.

If the carpet area is reduced through the course of the construction, the builder will have to refund the excess amount within 45 days, with an annual interest, to the buyer. In case of an increase in the carpet area, the developer can also ask the buyer to pay the excess amount.

However, RERA caps the upper limit of the increase in the carpet area at 3%. Built-up area: The built-up area in your flat or apartment is the carpet area plus the area that is covered by the inner walls and the balcony. In housing apartments in India, nearly 30% of a housing unit’s entire area is used in creating the inner walls and the balconies.

This means if the developer tells you that the built-up area of the unit is 1,000 sq ft., you could assume that the net usable area or carpet area of the apartment will not exceed 700 sq ft.

  1. As per RERA, the built-up area includes the carpet area plus the extra areas certified by the authorities, such as the area of the outer and inner walls, dry balcony area, etc.
  2. Built-up area calculation:
  3. Carpet area + wall area + excluding balcony and corridor = Built-up area.
  4. Super built-up area:

A housing society consists of various common areas, such as the corridor, lift lobby, elevator etc. and the buyer has to pay a monthly maintenance charge for the upkeep of these areas. The maintenance is a proportionate part of these spaces at the time of the purchase.

Builders typically use the loading factor – constructed spaces not exclusively allocated to the buyer – on the carpet area, to arrive at the super built-up area. In some cases, builders even include amenities, such as pools, gardens and clubhouses in the common area. Before RERA made it mandatory for builders to sell flats based on the carpet area, they widely used the super-built-up area as the space measuring unit, to cash in on the lack of clarity on space calculation.

The use of super built-up area as a measuring unit, helped them to lower the per sq. ft. cost of the property. It also gave the buyers a false impression that they were investing in a large home, when they actually were not.

  • Super built-up area = Built-up area + proportionate common area.
  • Or
  • Super built-up area = Carpet area (1+loading factor)
  • What is included in the super built-up area?
  • Built up area of the flat
  • Clubhouses
  • Lift & staircases
  • Lobby
  • Swimming pool
  • Gymnasium.

Any other common facilities for the residents. Loading factor: It is the difference between the super built-up area and the carpet area of your flat. It is used to add constructed spaces, not exclusively allocated to you. It includes shared areas like lifts, lobbies, staircases, and amenities, as well as a part of your terrace and balcony.

The loading factor of 1.20 means that your builder has added 20% to your carpet area. If the residential project does not have many amenities, the loading factor will be small. In most cases, a loading factor of 1.30 is considered sufficient. As a buyer, always ask the builder about the carpet area of the property and negotiate the price based on this area.

When you are comparing different projects or properties always compare the price per square feet on the carpet area and not the built-up or super built-up area. This will ensure that your comparison is accurate and the quoted price is correct and suitable when compared with the prevailing prices in the area.

Another important checkpoint is the Bank’s assessment; in case you are applying for a loan. The Bank would send a technical expert to visit and appraise the property. You can check with them, if the carpet area, as told to you by the builder, is the same, as assessed by them. In case of any discrepancies, you must point out this issue to the builder and renegotiate the price.

What is ground coverage area?

Ground Coverage means the ground area covered by the building immediately above the plinth level. The area covered by the following in the open spaces is excluded from covered area.

What is FSI and coverage?

FSI (Floor Space Index), also known as FAR (Floor Area Ratio), is one of the most important elements of real estate. FSI refers to the maximum permitted area on a piece of land for construction. The FSI is the ratio of floor area covered to the available land area.

  • FSI, which is usually set based on the National Building Code, is regulated by the municipal or local authorities of the state government.
  • The National Building Code of India provides guidelines for building construction activities across the country.
  • The attractiveness of the location and its population density can be understood through the FSI.

Also, even from an environmental standpoint, it is extremely crucial to know the FSI. Homebuyers must consider this because there are usually fewer open spaces if the FSI is high.

How is Rera area calculated?

It is easy to calculate the RERA carpet area or RERA carpet area calculator because the carpet area is 70% of the built-up area in most cases. For example, if the built area of a property is 2000 sq ft, then its carpet area would be 1400 sq ft.

What size is 1 plot of land?

How big is a standard plot of land in Nigeria? – Although there is no standard definition, the typical plot of land in Nigeria stands at around 100 ft x 100 ft = 30 m x 30 m = 10,000 square feet = 900 square meters. In this case, a half plot can be considered to be 50 ft x 100 ft = 15 m x 30 m = 5000 square feet = 450 square meters.

How do you calculate area in surveying?

The main objective of the surveying is to compute the areas and volumes. Generally, the lands will be of irregular shaped polygons. There are formulae readily available for regular polygons like, triangle, rectangle, square and other polygons. But for determining the areas of irregular polygons, different methods are used.

Earthwork computation is involved in the excavation of channels, digging of trenches for laying underground pipelines, formation of bunds, earthen embankments, digging farm ponds, land levelling and smoothening. In most of the computation the cross sectional areas at different interval along the length of the channels and embankments are first calculated and the volume of the prismoids are obtained between successive cross section either by trapezoidal or prismoidal formula.

Calculation of area is carried out by any one of the following methods: a) Mid-ordinate method b) Average ordinate method c) Trapezoidal rule d) Simpson’s rule The mid-ordinate rule Consider figure. Let O 1, O 2, O 3, O 4,On= ordinates at equal intervals l=length of base line d= common distance between ordinates h 1,h 2,.h n =mid-ordinates Area = common distance* sum of mid-ordinates Average ordinate method Let O 1, O 2,,O n =ordinates or offsets at regular intervals l= length of base line n= number of divisions n+1= number of ordinates THE TRAPEZOIDAL RULE While applying the trapezoidal rule, boundaries between the ends of ordinates are assumed to be straight. Thus the areas enclosed between the base line and the irregular boundary line are considered as trapezoids. Let O1, O2,,On=ordinate at equal intervals, and d= common distance between two ordinates Total area=d/2 Thus the trapezoidal rule may be stated as follows: To the sum of the first and last ordinate, twice the sum of intermediate ordinates is added. This total sum is multiplied by the common distance. Half of this product is the required area. Limitation: There is no limitation for this rule. Let O 1, O 2, O 3 = three consecutive ordinates d= common distance between the ordinates area AFeDC= area of trapezium AFDC+ area of segment FeDEF Here, Area of segment= 2/3* area of parallelogram FfdD = 2/3* eE*2d = 2/3 * *2d So, the area between the first two divisions, = d/3(O 1 +4O 2 +O 3 ) Similarly, the area of next two divisions ∆ 2 = d/3(O 1 +4O 2 +O 3 ) and so on Total area = d/3 Thus the rule may be stated as the follows To the sum of the first and the last ordinate, four times the sum of even ordinates and twice the sum of the remaining odd ordinates are added. This total sum is multiplied by the common distance. One third of this product is the required area.

Trapezoidal rule Simpson’s rule

The boundary between the ordinates is considered to be straight

There is no limitation. It can be applied for any number of ordinates

It gives an approximate result

The boundary between the ordinates is considered to be an arc of a parabola To apply this rule, the number of ordinates must be odd It gives a more accurate result.

Note: sometimes one or both the end of the ordinates may be zero. However they must be taken into account while applying these rules. Worked- out problems Problem 1: The following offsets were taken from a chain line to an irregular boundary line at an interval of 10 m: 0, 2.50, 3.50, 5.00, 4.60, 3.20, 0 m Compute the area between the chain line, the irregular boundary line and the end of offsets by: a) mid ordinate rule b) the average –ordinate rule c) the trapezoidal rule d) Simpson’s rule Solution: (Refer fig) Mid-ordinate rule: Required area= 10(1.25+3.00+4.25+3.90+1.60) = 10*18.80=188 m 2 By average-ordinate rule: Here d=10 m and n=6(no of devices) Base length= 10*6=60 m Number of ordinates= 7 Required area=10((1.25+3.00+5.00+4.60+3.20+0)/7) By trapezoidal rule: Here d=10m Required area=10/2 = 5*37.60=188 m 2 By Simpson’s rule: d=10m required area=10/3 = 10/3 =10/3*59.00 10/3*59= 196.66m 2 Problem 2: T he following offsets were taken at 15 m intervals from a survey line to an irregular boundary line 3.50,4.30, 6.75, 5.25, 7.50, 8.80, 7.90, 6.40, 4.40, 3.25 m Calculate the area enclosed between the survey line, the irregular boundary line, and the offsets, by: a) the trapezoidal rule b) simpson’s rule solution: a) the trapezoidal rule required area=15/2 = 15/2 = 820.125 m 2 c) simpson’s rule if this rule is to be applied, the number of ordinates must be odd. But here the number of ordinates must be odd. But here the number of ordinate is even(ten). So, simpson’s rule is applied from O 1 to O 9 and the area between O 9 and O 10 is found out by the trapezoidal rule. here the intervals between the offsets are not reglar through out the length. So, the section is divided into three compartments Let ∆ I = area of the first section ∆ II = area of 2 nd section ∆ III = area of 3 rd section Here d1= 5 m d2=10 m d3=20 m a) by trapezoidal rule ∆ I = 5/2 = 89.50 m 2 ∆ II = 10/2 =106.50 m 2 ∆ III = 20/2 = 158.00 m 2 Total area = 89.50+106.50+158.00 = 354.00 m 2 b) by simpson’s rule ∆ I = 5/3 = 89.66 m 2 ∆ II = 10/3 =102.33 m 2 ∆ III = 20/3 = 157.33 m 2 Total area= 89.66+102.33+157.33 = 349.32 m 2 FORMULA FOR CALCULATION OF VOLUME: D= common distance between the sections A. trapezoidal rule volume (cutting or filling), V=D/2(A1+An+2(A2+A3+.+An-1))

Does plinth area include roof?

1. What is Plinth Area of a Building? – The plinth area of a building or structure is the area of the ground covered by the building or structure, excluding any part of it that is above ground level. The plinth area of a building is equal to the gross floor area minus the base area (or basement) of that building.

Is DPC and plinth same?

Plinth Beam PB – Plinth beam is an alternate water barrier and true scientific and engineering method for protection from seepage. Unfortunately due to the higher cost of this method, it is rarely used in brick structure constructions. In frame structure houses or buildings, it becomes necessity.

  1. A plinth beam as its name suggests is reinforced cement concrete which is made with concrete mix along with the mesh of reinforcement/steel.
  2. Once foundations are at the first level of water barrier, instead of first DPC, plinth beam is directly placed which is 12 inches of 1 ft in height and width in accordance with the size of foundations.

Before pouring the concrete, steel mesh is prepared and placed as per the instructions of structural engineer, formwork (shuttering) is done along the path of plinth beam in required sizes and concrete is poured. Addition of water proofing chemicals and plasticizers is recommended. How To Calculate Covered Area In Construction Plinth beam provides 100% protection from seepage unlike the DPC. Other than providing best protection as water barrier and from seepage, it also provides unmatched strength to house as compared to normal DPC and acts as a binding/tie beam too for foundations.

Is staircase included in plinth area?

Staircase room or head room other than terrace level. Machine room. Porch. Open projections of veranda, balconies and parapets, if the area is protected by projections, full area is included in plinth area, if the area is un-protected by projections, 50% of the area is included.

What is the difference between covered area and carpet area?

What is the meaning of carpet area? Carpet area means the net usable floor area of an apartment, excluding the area covered by the external walls, areas under services, shafts, balcony. However, it includes the area covered by the internal partition walls of the apartment.

What is fully enclosed covered area?

Construction cost calculations explained – The BMT Construction Cost Table is a useful guide and calculates costs based on the Gross Floor Area (GFA) rate. The GFA rate is based off two important elements. The first being the Fully Enclosed Covered Area (FECA) that includes items like staircases, basements, columns and piers.
