6 IMPORTANT DOCUMENTS THAT NEEDED IN HOME BUYING PROCESS

 

6 IMPORTANT DOCUMENTS THAT NEEDED IN HOME BUYING PROCESS

1) The Sale Deed

One of the essential legal documents during property investment, the Sale Deed contains evidence of the sale and the transfer of property from the builder to the buyer. This document is the one that states that you own the property, and it should be kept safe for the coming years. Wondering why? Years after buying the home, you may choose to sell your house to someone else and in this case, the requirement of the sale deed is inevitable. Usually, the Sale Deed is drafted before the sale agreement, once the concerned buyer and the seller give a green signal on the terms and conditions detailed in the sale agreement.

2) The Mother Deed

Want to trace the ownership of a property? All you must do is find the Mother Deed. The Mother Deed traces the ownership of the property. And thus, this document is generally required by banks when a buyer avails a loan on the property. A buyer may approach the local government authorities to assist them in the drafting of this document.

3) The Sale and Purchase Agreement

The Sale and Purchase Agreement encloses a list of terms and conditions that are agreed upon by both the buyer and the seller. These will include the negotiated price of the property, the date of moving in, and the like. Thus, the agreement will contain information on the deal like the agreed amount of the flat by both the buyer and the seller.

4) The Building Approval Plan

Before beginning construction in a particular location, the builder is required to get the necessary sanctions from the authorities, which gives the builder the nod to start the construction. This sanction may depend upon the land chosen by the builder and the building designs. 

5) The Completion Certificate/ Occupancy Certificate

The Completion Certificate, also known as the Occupancy Certificate, is a document that certifies that the building has been inspected and that it complies with all municipal or local development authority rules. This paperwork is required to avail services including water, power, and waste management.

(It is not ideal for a first-time home buyer to purchase a property without a Completion Certificate because the property is considered illegal without it, which can result in a penalty or even eviction. However, in case if the builder fails, the buyer can approach the municipal corporation and request a Completion Certificate which will prove his/her ownership over the property)

 6) The Possession Letter

The Possession letter is a document created by the builder that specifies when the buyer will take ownership of the property. This document is prepared under the builder's name after the Completion Certificate is obtained. This letter, however, does not prove the ownership of the property. Now that you have already read about the Occupancy Certificate, you know how to prove the ownership of the  real estate property.

As you are aware of the documentation involved in the real estate industry, you can go ahead and buy your dream property with a peaceful mind. If you are still doubtful make sure that you buy from a builder who upholds their ethics. 

SAFE BEARING CAPACITY OF SOIL

 SBC OF SOIL

The safe bearing capacity of soil is defined as the maximum load per unit area that the soil can bear without any displacement or settlement. This is measured in terms of kilograms per square centimeter. If the load exceeds this mark, the soil will start to displace or break. This will lead to structure settlement, which can end up in destructive results.

Formula:
Safe bearing capacity of soil = (ultimate bearing capacity)/(Cross-section area x Factor of safety)

          *The ultimate bearing capacity of the soil - the point at which the soil starts to displace under load. Any soil can take up to a certain amount of load only, after which it starts to settle or displace.

           *The cross-section area is the area of soil on site on which the tests are being performed. It can be a square meter in general practice.

          *The factor of safety indicates how safe the soil capacity results must be before considering a certain type of construction. Naturally, it depends upon the type of building being constructed. It is kept at 2 for general civil constructions and 3 for high-rise or heavy constructions.

Testing Procedures for Soil Bearing Capacity

Drop Weight Method is the easiest and it is a tried and tested true test.

Drop Weight Test:

1. Dig up a pit down to the foundation depth.

2. Find a heavy perfectly cube-shaped object. Stone blocks work best. Measure its precise weight.

3. Lift the cube up to a predetermined height directly over the pit. This must be precise as well.

4. Drop the cube in the pit, and then carefully lift it out without disturbing the impression made by the block.

5. Measure the depth of the impression made by the block.

6. Repeat the above process several times and take the average value.

Example:

Weight of the block: 1.2 kg
Height of drop: 120cm
Depth of impression: 1.6cm
Cross section: 20 sq.cm.
Factor of safety: 2

Therefore, ultimate bearing capacity = (1.2 x 120)/1.6 = 90

And, safe bearing capacity of soil = 90/(20 x 2) = 2.25 kg/cm2.

KNOW ABOUT CONCRETE COVER AND COVER BLOCKS

 CONCRETE COVER AND COVER BLOCKS

NOMINAL COVER (or Clear Cover)

Nominal cover is the design depth of concrete cover to all steel reinforcements, ,including links. It is the dimension used in design and indicated in the drawings. It shall be not less than the diameter of the bar.

Nominal Cover to Meet Durability Requirement

Minimum values for the nominal cover of normal weight aggregate concrete which should be provided to all reinforcement, including links depending.on the condition of exposure described below:

Exposure

Nominal Cover in mm

( not less than)

Mild

20

Moderate

30

Severe

45

Very Severe

50

Extreme

75


NOTES
1. For main reinforcement up to 12 mm diameter bar for mild exposure the nominal cover may be
reduced by 5 mm.
2. Unless specified otherwise, actual concrete cover should not deviate from the required nominal cover by +I0 mm
3. For exposure condition ‘severe’ and ‘very severe’, reduction of 5 mm may be made, where cpncrete grade is M35 and above.

 * However for a longitudinal reinforcing bar in a column nominal cover shall in any case not be less than 40 mm, or less than the diameter of such bar. In the case of columns of minimum dimension of 200 mm or under, whose reinforcing bars do not exceed 12 mm, a nominal cover of 25 mm may be used.

 * For footings minimum cover shall be 50 mm.

 For Minimum values of nominal cover of normal-weight aggregate concrete to be provided to all reinforcement including links to meet specified period of fire resistance, refer in code section - 26.4.3

--------------------------------

There is no maximum cover, but the combination of inherent shrinkage and other factors may make excessive cover break away from underlying concrete 

Minimum Concrete Cover for Reinforcement

Below are the specifications for reinforcement cover for different structural members in different conditions.

a) At each end of reinforcing bar, concrete cover not less that 25 mm or less than twice the diameter of the bar should be provided.

 b) For a longitudinal reinforcing bar in a column, concrete cover not less than 40 mm not less than the diameter of such bar should be provided. In case of columns of minimum dimension of 20 cm or under, whose reinforcing bars do no not exceed 12 mm, concrete cover of 25 mm to be used for reinforcement. 

c) For longitudinal reinforcing bars in a beam, not less than 30 mm or less than the diameter of the bar.

 d) For tensile, compressive shear or other reinforcements in a slab or wall not less than 15 mm, not less that the diameter of such bar. 

e) For any other reinforcement not less than 15 mm, concrete cover not less than the diameter of such bar.

 f) For footings and other principal structural members in which the concrete is deposited directly against the ground, cover to the bottom reinforcement shall be 75 mm. If concrete is poured on a layer of lean concrete, the bottom cover maybe reduced to 50 mm. 

g) For concrete surfaces exposed to the weather or the ground after removal of forms, such as retaining walls, grade beams, footing sides and top etc. cover should not be less than 50 mm.

 h) Increased cover thickness shall be provided as indicated on the drawings, for surfaces exposed to the action of harmful chemicals (or exposed to earth contaminated by such chemicals), acid, alkali, saline atmosphere, sulphur, smoke etc.

 i) For liquid retaining structures, the minimum cover to all steel shall be 40mm or the diameter of the main bar, whichever is greater. In the presence of sea water and oils and waters of a corrosive character the covers, shall be increased by 10 mm.

 j) Protection to reinforcement in case of concrete exposed to harmful surroundings may also be given by providing a dense impermeable concrete with approved protective coatings. In such a case the extra cover mentioned in (b) & (i) above may be reduced.

 k) The correct cover shall be maintained by cement mortar cubes (blocks) or other approved means. Reinforcements for footings, grade beams and slabs on a sub-grade shall be supported on precast concrete blocks as approved by EIC. The use of pebbles or stones shall not be permitted. 

l) The minimum clear distance between reinforcing bars shall be in accordance with IS:456 – 2000 or as shown in drawing.

CONCRETE COVER BLOCKS

Cover block is a precast concrete block to provide the necessary cover or spacing for the

reinforcement bars from the formwork. PVC or Plastic Cover blocks are also available.

By placing Cover blocks, rebar gets proper bonding with concrete and saved from  corrosion.

The distance between the two cover blocks depends upon the diameter of the rebar, the type of  RCC structure, and rebar directions (longitudinal or transverse). When the rebar diameter increases there will be less sagging and hence the number of cover blocks requirement becomes less as the bar dia. increases.

Average distance between Cover blocks

 Slabs - For 8mm - 60 cm and for 10mm - 70 cm. For 100 Sqm, approx. 280 nos. required for 8 mm bars and approx. 210 nos. required for 10 mm bars.

Columns - all sides, for 12mm - 20mm - 60 -90 Cm and above 20mm - 100 cm spacing required.

Beams - 12mm - 20 mm - 40 -70 Cm and above 20 mm - 80 Cm required.

Footings - 60 - 70 Cm required

Various types of Cover blocks

Single Cover spacers, Multiple Cover Spacers and Circular Spacers are in precast concrete blocks.

Clip Spacers, wheel spacers and chair spacers are PVC material blocks.
