Procedure

Step by Step Process Flow for Residential House Construction

I) Pre-construction Steps:

If you are an aspiring homeowner and wish to construct your dream home, the first step is to find the right plot in the location and size preferred by you while ensuring that it is free of litigations or disputes. You can approach a well-experienced lawyer and the BDA (or a similar body operational in the region you choose) to check for the site’s authenticity. Clearing the land with the BDA and getting floor plans sanctioned by the BBMP are crucial aspects of house construction. The chosen plot should be well connected with amenities that you and your family require not just in the present, but in the future too. Observing the recent development of the location can also certify a steady rate of appreciation for your investment. While you finalize your plot, it is also important to check for the nature of the soil and do a soil test; the land can be a paddy field, agricultural field, or a plot with hard soil. This is crucial as the construction cost can turn exorbitant for the laying of the foundation depending on the nature of soil it is built upon. Once you find the right plot, take the help of a construction calculator to give you an overall estimate of the expenditure to build the home of your liking. Subsequently, you can approach one of the good architecture firms in Bangalore to help you visualize and plan your dream abode. If you seek to buy a flat or a villa, it is important to choose a project that is well connected offering a range of amenities with superior quality construction and appreciation value. You can learn more about the different house builders in Bangalore through customer reviews and make an informed decision about what you wish to purchase. Top builders in Bangalore generally ensure that they choose a location that has a wholesome approach and shows good potential as an investment.

Seek technical help

Use the estimate provided by the construction calculator to set a benchmark for the construction cost per square foot. Compare the rate of construction cost per square foot that varied house builders in Bangalore are offering. Architecture firms in Bangalore can help you plan your home and offer you design solutions based on your preference.

Choosing the right team of consultants

There are many good architecture firms in Bangalore that can be approached to build your dream home. It is important to work with someone who understands your aspirations, limitations, and schedule in order to complete your dream abode peacefully and in time. The efficiency of the architect in providing you the most optimised solution and their ability to work with other consultants must not be overlooked. Your house construction is the result of the teamwork of different consultants like architects, civil engineers, electrical engineers, etc. Thus, all of them have to be experienced and reliable to make the house construction a smooth sailing process. While you work with your architect to finalize the design, the specifications like roles and responsibilities, payments, the material used, labour, schedule, etc. have to be documented properly. A contract has to be laid out for the benefit of both parties involved to ensure that the project is completed as specified. The role of your team doesn’t end with the completion of the house construction, but they will have to offer continued support after you occupy the home and may need some minor works to be done.

Planning your finances

Once you have an estimate and a design at hand, you can start looking at the finer details like the material and finishes to be used. It is important to look into these factors at this stage as this further defines the cost of your home. If you are having any financial restrictions, this would be the right time to apply for a home loan. You will have to submit the license for construction, plans approved by the BBMP, and legitimate documents in order to secure a loan. Planning your finances is important in order to ensure that you have ample money to see the construction through. Lack of financial planning and organisation can cause an infinite delay in the completion of your home.

Permissions and paperwork

No construction can begin until you have permission from the BBMP. Architecture firms in Bangalore can provide you with plans that are done in adherence to the bylaws of the region you are constructing in. You will need various documents along with drawings that will help you get permission to build. Some of the documents that you may need are listed below. But it is important to remember that these documents can vary depending on the municipal body that you are dealing with:
  • Architectural drawings: Detailed drawings in adherence to the bylaws have to be provided.
  • Architect’s Certificate of Company Record and Civil Engineer’s Certificate on Record: The license and other details of your architect and engineer have to be submitted.
Along with the sanction from BBMP, you will also need many other approvals and permissions like:
  • Approval to dig a borewell
  • Approval to cut trees if required
  • BBMP/BDA Plan approval
  • BESCOM/KEB- Temp Connection
While the ones above are needed before the construction begins, there are some more permissions that you will require before occupying your home. Some of the post-construction legalities are mentioned below:
  • BESCOM/KEB connection for your home is essential to ensure that your home has electricity running before you occupy it.
  • BWSSB water connection on a permanent basis is crucial. Some localities like new layouts and developments might not have this facility, in which case it is important to contact the local municipal bodies to find out more about the alternatives.

II) Building Construction Stage Process

  1. Site Planning or Levelling:
    The first step is to clean the site thoroughly and to do research about the content on the site. One might find roots of trees, debris, etc which will have to be removed and the site will have to be levelled. Usually, after the site is levelled, a temporary shed is built with a temporary power supply.
  2. Layout Marking:
    The accepted design boundaries are marked in the initial stage of the house construction on the levelled site. After this, the precise dimensions and layout for the foundation is chalked out.
  3. Excavation:
    Depending on the structural design provided by the structural engineer, the excavation is done to facilitate the laying of the foundation. Top builders in Bangalore might excavate much deeper as they would have to build a high rise structure along with multi-level basements. The dimensions of the excavation depend on many factors like the height of the structure, nature of the soil, etc.
  4. The laying of the foundation comprises of many activities. They are as listed below:
    • Compacting the ground: The excavated pits are trimmed and evened out where the base is compacted using hand compactors.
    • PCC: In order to create a stable foundation the reinforcement is tied and the footing is positioned, PCC has to be laid. A simple cement concrete mixture in the proportions of 1:4:8 or 1:3:6 is laid at varying depths on the compacted earth.
    • Footing Reinforcement: Reinforced steel bars are tied together and integrated into the PCC to form a foundation. The concrete is then poured and the rods of the columns are removed.
    • Shuttering: This has to be done in accordance with the drawings as provided by the structural engineer. Shuttering is crucial to achieving the dimensions and shape as specified in the drawings. It is used to keep the concrete in shape till it sets completely and prevents any contact with the soil.
    • Footing Concrete: Before any more concrete work is undertaken, it is important to check the foundation. If the excavated depths have to be in line with the drawings. If there is any variation, more concrete is poured in as per the site map. Foundation depth ranges from 9 “to 18”, but a standard of 12 “depth is used in most cases. The width of the base is held equal to its profundity.
  5. Column Casting:
    The shuttering base is fastened to cast the columns. Concrete is poured into the framework at intervals as mentioned in the structural drawings. Usually, the shuttering is removed after 24hrs of casting and curing is finished.
  6. Wall Construction:
    There are different types of masonry and material that can be used in house construction. One can use stone masonry, wooden walls, burnt bricks, hollow blocks, and many others. Housebuilders in Bangalore also use prefabricated concrete walls, different types of concrete blocks depending on the scale of construction, and their budget. The foundation of the wall is first built using concrete or stone masonry. Required opening for doors, windows, and ventilators are created and the masonry is done to create spatial segregation as specified by the architectural drawings
  7. Lintel:
    The framework and masonry are the most time-consuming activities undertaken. During the masonry, openings are created and the tops of the openings are strengthened with reinforced concrete panels with cement. The wooden frames are then attached to this so that the weight of the structure does not impact the wooden members directly.
  8. Roofing:
    The final concrete roofing is poured after the masonry work is completed. The thickness of the slab and the amount of reinforcement to be used and other specifications will be as per the drawings and details provided by the structural engineer.
  9. Plastering:
    No work is done for about 14 days after the slab is laid. Plastering begins once the slab is completely set. Usually, a mortar is created using the standard proportions of 1:3 or 1:4 for plasterwork. The thickness of the plastering will not be more than 0.75inches. It takes about 7 days to cure on the surface. Plastering is not just done for concrete members but for brick masonry as well. It adds to the strength of the walls and any gaps or crevices are filled using plaster.
  10. Attachment of doors and windows:
    Housebuilders in Bangalore often prefer to use timber doors and windows. Apart from this, steel or aluminium fixtures can also be used. If one is opting for wooden doors and windows, then the frames are set within the masonry of the walls. After the plastering is completed, the frames are placed and the panels are fastened in place with hinges. If one is opting for aluminium or steel doors or windows, these can be installed after the painting is done.
  11. Electrical and plumbing work:
    Grouting and sunken slabs etc. are creating while the concrete is laid and masonry is undertaken. But the wiring, installation of switchboards, etc. is undertaken after the plastering is done. All the plumbing and electrical work are done before the painting and tiling is done so as to ensure that little damage occurs to the final finished space.
  12. Tiling and flooring:
    While there is no restriction on where tiles can be used, we most frequently see them on the walls of bathrooms and kitchens. Wall tiles are installed first, followed by the laying of floor tiles. There are many options that one can choose from when it comes to tiling and flooring. They can choose from marble, granite, bricks, epoxy, etc. while wooden flooring is also becoming a popular choice, especially for bedrooms.
  13. Painting:
    The last stage of your house construction is the painting. There are many options available in the market depending on your preference and budget. There is 1 layer of primer and 2 layers of water-based paint or 2 coat of putty and 2 coat of paint for seamless coating. There are also different paints and finishes that you can choose for internal and external surfaces. Apart from this, woodwork and wallpapers are now a trend and are much sought after as wall finishes.
