2021-07-07T10:52:00.000+05:30

If you want to starts your consultancy for building planning you should know how to draw a plan for a building permit under Panchayat area, you need to know some rules & guidelines given in accordance to the Panchayat Administration Rule [reference:The West Bengal Panchayat (Gram Panchayat Administration) Rules, 2004].

While preparing plan you need to aware of these rule as well as follow & implement this parameters on the technical drawing for getting hassle free permission from local Panchayat Authorities.

Panchayat guidelines for Building Construction:

With respect to Gram or Grams as may be specified by the State Government by notification, a plan for new structure or building within the jurisdiction of a Gram Panchayat shall have reasonable provision for:

1. Guidelines for Drainage & Sanitary facilities:

Adequate drainage facility by means of access and passage leading to existing public drains or drainage channels or by means of soak-pit having adequate capacity.( As thumb rule ₹the capacity of soak-pit is calculated in accordance to 600 lit/person )

2. Guidelines for Approach road or passage for building:

If an existing passage or road over which the public have a right of way, is less than one and eight-tenth metres (approx 6 feet)wide, the plot-holders on either side of such passage or road shall keep a front set-back in such manner as to allow a front set-back of nine-tenth metre (approx 3 feet) on either side of the road after leaving in the middle a clear passage of one and eight-tenth metres and a rear set back of one and eight-tenth meter.

if a Gram Panchayat is of the opinion that an existing building or part thereof should be set-back (where set back is not provided according to rule) to allow a regular passage or road of not less than one eight-tenth metres(Approx 6 feet) in pursuance of any development plan, the Gram Panchayat, after giving the owner of such building an opportunity of being heard, may refer a proposal through the Panchayat Samiti to the Land Acquisition Collector for acquisition of the land in question.

Whenever there is a service road or approach passage available, no direct access from a building shall be permitted to a public road.

3. Guidelines for Maximum coverage of residential building:

The maximum building area occupancy of an individual plot shall be 2/3 rd of the total area for a residential building.

1/3 rd of the total plot area that shall be kept vacant including front & rear setback spaces which are left free for road or passage purpose.

The Gram Panchayat shall refuse all such applications for permission of any addition to an existing structure or building if the existing coverage added with the proposed addition exceeds 2/3 rd of the total plot area.

4. Guidelines for Construction of residential building:

Any structure or a building within the jurisdiction of a Gram Panchayat shall be erected or constructed with a set-back of at least nine-tenth metre (approx 3 feet) from each side of the plot. In doing so, there shall be a minimum perpendicular distance of one and eight-tenth metres (Approx 6 feet) from the side of any proposed new building to the side of an existing building.

The height of a new or existing structure shall be 1.5 times the width of the approach road added with the width of the front set back of that building (No set back or space left inside the building will not comes under this calculation), but within 15 m height as per rule up to which panchayat can grant permission.

5. Guidelines for Dimension & height standard for interior:

Habitable room: The area of a habitable room ("habitable room" means a room meant for human habitation other than a kitchen, bath, water closet or storeroom) should be occupy minimum area of 6 square meter (approx 65 Square feet), the minimum length of one of its sides should be 1.5 m ( 5 feet).

The height of all habitable and multipurpose rooms shall not be less than 2.6 metres (Approx 8.5 ft) from the surface of the floor to the lowest point of the ceiling.

Inhabitable rooms: The area of inhabitable rooms (Bath, water closet, Bathroom with water closet, kitchen,corridor etc.) should not be less than 0.8 square meter (approx 8.6 square feet), the minimum dimension one of its sides should be 0.85 m (approx 2.75 feet).

The minimum height of these inhabitable rooms from floor to the lowest point of ceiling should be 2.1 m (approx 6.9 feet).

6. Guidelines for Restriction on construction over tank and water body:

Gram Panchayat shall not give permission to any erection or construction by filling up any tank, pond, or other water body, marshy land or abandoned brick-field or sand quarry, coal mine, mineral quarry or any other water area.

7. Guidelines for Prohibition of dry latrine:

Gram Panchayat shall not accord permission for erection or construction of a dry latrine either in an existing building or as a part of a new construction.

8. Guidelines for Classification of land for construction:

If any structure or building is proposed to be erected or constructed on any land recorded otherwise than as "homestead" land, the Gram Panchayat shall withhold permission for such erection or construction until the applicant produces an order allowing change of classification of the said land by the Collector or any other competent authority having jurisdiction under any law for the time being in force.

9.Restriction for construction in the vicinity of airport:

No person shall erect near or in the vicinity of any airport or of a prohibited area, any structure or building, tending to hazard aviation or security, as the case may be. The Gram Panchayat, on receipt of such application shall cause an examination and inquiry and forward the application within thirty days from the date of its receipt to the Zilla Parishad with comments; the Zilla Parishad on receipt of the application and the comments of the Gram Panchayat, shall –

(a) approve the proposal and the plan with or without any modification, or

(b) refuse the proposal and the plan, and return the application and other papers within thirty days from the date of its receipt by the Zilla Parisahd.

The Gram Panchayat suppose to procces the application within 90 days from receipt.

On receipt of the application, the Gram Panchayat or Panchayat Samiti or designated office shall check the completeness of the application and issue an acknowledgement to the applicant (in West bengal Form I of the WB Right to Public Services Rules, 2013) by noting down the date within which the service shall be provided and defect in the application, if any, that needs to be rectified.
The Gram Panchayat or the Panchayat Samiti thereafter shall start processing of the application by cheeking the guidelines mentioned earlier in the article is followed or not (But in reality the Authorities rarely audit the sites), if all the documents are found genuine and are in conformity with the requirement of the said Rules, the Gram Panchayat or the Panchayat Samiti shall either approve the building plan and the site plan and issue permission letter directly or to send the building and site plan to the appropriate authority for vetting which also i have mentioned in the table before.
If the Gram Panchayat or Panchayat Samiti, as the case may be found any violation of the guidelines they will withhold or refuse to grant such permission and communicate the decision of the Gram Panchayat or Panchayat Samiti to the applicant stating reasons for doing so.
On receipt of the vetted plan from the appropriate authority, Gram Panchayat or Panchayat Samiti, as the case may be, shall retain a copy of the vetted plan in its office and hand over the permission letter along with copies of the vetted building and site plan to the applicant.

Stipulated time period for providing service :

The Pradhan of GP or the Executive Officer of PS concerned, as the case may be, shall accord permission for erection of new structure or building or making addition to an existing structure or building within 60 days time period from the date of receipt of the application at the office of Gram Panchayat or Panchayat Samiti.

Right to Appeal against the decision of the Gram Panchayat:

If the permission is not accorded within the stipulated time period mentioned above, the applicant may prefer an appeal before Appellate Authority (For W.B Appeal to be made in Form II of the WB Right to Public Services Rules, 2013).

If the Appellate Authority fails to dispose the appeal within the time period the applicant may also appeal before the reviewing officer (For W.B Appeal to be made in Form III of the WB Right to Public Services Rules, 2013).

	Additional Construction/ Remodeling /Alteration	Nil	Rs. 150	Rs. 250	Rs. 1.50	Rs. 2.50

Conclusion:

For the permission of construction apart from paying the amount according to the rate chart you have to pay a donation amount which varies from 3k-5k (It's not mandatory to pay the amount for all panchayat but as per my experience i have seen it most of them).
In most of the cases the dedicated authority not visit the site of construction & this is reality.
But from the guidelines given by Panchayat you should strictly follow the 3ft set-back rule.(although this also depends upon the relationship to your neighbors).
Until & unless you do something silly or behaving arrogantly with authorities everything goes seamlessly.

Any point missed or correction required, please let me know in comment section.

How to calculate Effective Span of Beam & Slab As per IS 456 2000 in 2021

2021-06-03T15:22:00.005+05:30

Here we will learn with some simple examples how to calculate Effective Span of Beam & Slab of various type As per IS 456 2000 Clause 22.2.

Effective span: It is that length of Beam or Slab using which we can calculate the moment acting on it & it is further help us to design & analyze the members. (Show in Fig:1) [IS 456 2000 Clause 22.2]

Clear span: It is the clear distance between two supports over which the member (Beam or Slab) resting. (Shown in Fig :1)

Fig:1 Simply supported Beam & Slab

Effective depth: It is the distance between top most compression fiber of the concrete member (Beam or Slab) to the center of the tension reinforcement. (Shown in Fig:3) [All Beam & Slab here have same dimension profile shown below]

Fig:2 X-ray view of section of Beam

Fig:2.1 Cross Sectional view of Slab

Effective span is an important parameter for design & analysis of a structure parts like Beams & Slabs also its necessary for calculating “MOR” (Moment of resistance:the moment which can be safely withstand by a structure or parts of structure’s without showing any considerable deformation), but the effective span depends on lots of other factors, because of that we divided effective span into Four main categories:-

a) Simply supported Beam & Slab

b) Continuous Beam & Slab

c) Cantilever Beam & Slab

d) Frames

a) Simply supported Beam & Slab: The effective span of a member that is not built integrally (monolithic-ally) with its supports shall be taken as lesser than of these two: -

Clause (i): Clear Span (L) + effective depth (d) (shown in fig:2 &2.1)

Clause (ii): Clear Span (L) + support/2 +support/2 (Center to Center distance b/w support)

Fig:3 Simply supported beam with 200 mm wide support

Example 1: (as shown in fig 1; where span length= 3000 mm & width of support= 300 mm)

Clause i)

Effective span of the Beam = Clear Span (L) + effective depth (d)

= 3000 mm + 252 mm

= 3252 mm

Cause ii)

Effective span of the Beam = Clear Span (L) + support/2 +support/2 (Center to Center distance b/w support)

=3000 mm+300 mm/2+300 mm/2

=3300 mm

“here the Clause(i) is the deciding clause of the effective length (L)= 3252 mm < 3300 mm (Clause ii)”

Example 2: (as shown in fig 2; where span length= 3000 mm & width of support= 200 mm)

Clause i)

Effective span of the Beam = Clear Span (L) + effective depth (d)

= 3000 mm + 252 mm

= 3252 mm

Cause ii)

Effective span of the Beam = Clear Span (L) + support/2 +support/2 (Center to Center distance b/w support)

=3000 mm+300 mm/2+200 mm/2

= 3200 mm

“here the Clause(ii) is the deciding clause of the effective length (L)= 3200 mm < 3252 mm (Clause i)”

b) Continuous Beam or Slab: If the member (Beam or Slab) continuous over more than two support then it’s called continuous Slab or Beam.

if the width of the support is less than 1/12 of the clear span, the effective span of a continuous Beam or Slab is calculated as per clause (a) explain above. (As shown in Fig:4)

width of support < 1/12 of clear span

12 x width of support < clear span (we can write this expression mathematically)

“The clear span length should be greater than twelve times of width”

If the supports are wider than 1/12 of the clear span or 600 mm whichever is less, the effective span shall be taken by following below mentioned criteria’s

Width of support > 1/12 of clear span

12 x width of support > clear span (we can write this expression mathematically)

“The clear span should be less than twelve times of support width”

1) For end span with one end fixed and the other continuous or for intermediate spans. the effective span shall be the clear span between supports.

Effective span = Clear span

Fig 4: Continuous Beam with one end of the span ‘fixed’

Example: As shown in fig 4;

For span 1: effective span= clear span= 3500 mm
For Span 2: effective spa = clear span = 3400 mm (This is the intermediate span)

For Span 3: effective span= clear span = 3200 mm

[All span is less than twelve times of the width which is 3600 mm]

2) For end span with one end free & other continuous the effective span shall be equal to lesser of these TWO

Clause (i) Clear span + effective depth (d)/2

Clause (ii) Clear span + width of support/2

Fig 5: Continuous Beam or Slab with one end of the span ‘free’

Example 1: (as shown in fig 5; where span 1; clear span= 3500 mm; support width= 300 mm; effective depth=252 mm)

Clause (i) Clear span + effective depth (d)/2 = 3500 + 252/2 = 3626 mm

Clause (ii) Clear span + width of support /2 = 3500 + 300/2 = 3650 mm

Here clause (i) is the deciding clause for the effective length =3626 mm

Example 2(as shown in fig 5; where span 3; clear span= 3850 mm; support width= 200 mm; effective depth=252 mm)

Clause (i) Clear span + effective depth (d)/2 = 2300 + 252/2 = 2426 mm

Clause (ii) Clear span + width of support /2 = 2300 + 200/2 = 2400 mm

Here clause (ii) is the deciding clause for the effective length = 2400 mm

[All span is less than twelve times of the width which is 3600 mm & 2400 mm]

3) For Roller or Rocket bearing

Effective span = Center to center distance between support

= clear span + roller dia/2 + roller dia/2

= clear span +roller radius +roller radius

= clear span + dia of roller

Fig: 6 Continuous roller supported Beam or Slab

Example: as show in fig 6; clear span =3400 mm; roller dia=250 mm

Effective span = clear span + dia of roller

= 3400 + 250

= 3650 mm

[All span is less than twelve times of the width which is 3600 mm]

c) Cantilever Beam & Slab: The cantilever beam or slab are categorized into two types for calculating their effective length there are:

Fixed at the end (not continuous over support): For these cantilever bear or slab effective length consider as the clear length from the face of the support plus effective depth. (as shown in fig:7)

Effective length = length from face of the support + effective depth(d)

Fig:7 Cantilever Beam or Slab fixed at end

Example: as show in fig 7; clear length =1350 mm; effective depth (d) = 252 mm

Effective length= 1350 mm + 252 mm

= 1602 mm

Continuous over support: The cantilever which is continuous over support to form a cantilever, the effective length of that cantilever should be taken as length from face of the support plus half the width of the support.

Effective length = length from face of the support + support width/2

Fig:8 Cantilever Beam or Slab continuous over support

Example: as show in fig 8; clear length =1410 mm; support width = 300 mm;

Effective length= 1410 mm + 300/2

= 1410 mm + 150 mm

= 1560 mm

d) Frame: For analysis of continuous frame center to center distance shall be consider for effective length.

Effective length= Center to center

= Clear span + width of support/2

Fig:9 Frame structure of Beam & Slab

Example: as show in fig 9; Frame 1; clear span =3600 mm; support width = 300 mm;

Effective length= 3600 mm + 300/2

= 3750 mm

how to calculate cement, sand and aggregate quantity in m15 concrete in 2021

2020-05-31T16:04:00.004+05:30

6.23 Bag of Cement, 12.48 bag of Sand & 25 bag of Aggregate is required for 1m3 of m15 concrete, mix with proportion of 1:2:4 cement, sand, aggregate respectively, the whole calculation with concept mention below.

Calculation for 1 m3 M15 grade concrete

In m15 concrete total proportion of materials is 7 (1 portion cement+2 portion sand +4 portion aggregate also known as stone chips).

So, in 1m3 concrete

Cement = 1/7 = 0.142 m3 is equals 4.05 Bag of cement (1 Bag of cement = 0.035 m3 in volume).
Sand = 2/7 = 0.285 m3 is equals 8.10 Bag of sand (measure in same Cement bag of 0.035 m3).
Aggregate = 4/7 = 0.571 m3 is equals 16.20 Bag of aggregate (measure in Cement bag of 0.035 m3).

The above calculation for dry volume of concrete for 1 m3 M15 concrete.

In practical we use wet concrete for casting, for this reason we have to consider the shrinkage of concrete because in combine with water dry concrete shrinks & reduced its volume with respect to the dry volume.

To get 1 m3 wet concrete we have to procure 1.54 m3 dry concrete.

Now to get the exact number of bags of cement, sand, aggregate for casting we have to multiply the dry volume (volume converted to bags) with multiplying factor 1.54 which is nothing but the ratio of wet to dry volume of concrete also known as shrinkage ratio of concrete.

Cement = 4.05 * 1.54 = 6.23 Bag of cement.
Sand = 8.10 * 1.54 = 12.48 Bag of sand .
Aggregate = 16.20 * 1.54 = 25 Bag of aggregate.
