Steps for building a house

Building of house can be divided into two major parts:

1.       Constructing a grey structure
2.       Completing the Finishing work

We will share with you the steps for building a house. In this article, we will share with you the steps for grey structure only. For steps regarding finishing of house we will soon be sharing another article. We will only be dealing with brick structure in the content below. For frame structures don’t follow these steps. Following are the steps in grey structure while building a house:
       i.            Plot Demarcation
      ii.            Plot Chalking
     iii.            Excavation
     iv.            Laying the foundation
      v.            Construction of water and sewerage tank
     vi.            Pouring of Ghasu
    vii.            Building the walls
    viii.            Shuttering for concrete
     ix.            Lay the iron frame
      x.            Installation pipes on iron net on roof for electrical wiring
     xi.            Laying of lentar (mixture of cement, sand & bajri)
    xii.            Installation of pipes in walls for electrical wiring
   xiii.            Plumbing work
   xiv.            Cementing the floor and ramp
    xv.            Plaster of inside walls and roof
   xvi.            Lay of electrical wires and installation of Main DB (distribution box)
 xvii.            Plaster of outside structure

        I.            Plot Demarcation
Exact points are marked as per the dimensions of the plot

        II.            Plot Chalking
A sketch drawn with a chalk on the plot as per the approved house plan

       III.            Excavation
Excavation starts on the plot as per the chalking sketch and excavates it to the desired depth

      IV.            Lay the foundation
After excavation of the plot, work of laying the foundation starts. This type and design of foundation depends on the size of the house, the ground in which it is laid and building bye laws. The most commonly and cost effective type of foundation should be determined taking into consideration the height of the walls and the load it will be required to bear in terms of building itself as well as the impact of natural calamities like earth quake, heavy rains etc. One should use the bricks of best quality quality in foundation because stronger the foundation, the stronger will the structure be. Extra cooked bricks (Khinger) can also be used as they will serve the purpose of strength and they are available at cheaper price from the market. At this stage first round of termite spray should be conducted

        V.            Construction of water and sewerage tanks
When the foundation work completes, it is better to construct water and sewerage tanks as per drawing. Tanks construction right after the foundation is easy to make and saves the cost of ghasu (filling material)

      VI.            Pouring of Ghasu
Ghasu is a type of sand which has low quantity of mud. It is used to fill the blocks after the completion of foundation upto DPC level. The recommended way of pouring ghasu is through manual labour. The process does take extra time but is the safest. Using of machine/ crane takes less time but a little mishandling can damage the foundation. This step normally takes 8-10 days to complete

    VII.            Building the interior walls and boundary wall
Building walls of ground floor starts from DPC level and goes up to 10-12 feet as per the bye laws. If no bye laws are applicable, it comes to your discretion to decide that how high you want the roof to be.

   VIII.            Shuttering
Shuttering is the term used for temporary timber, metal or other material used to provide support to wet concrete till it gets strength for self support. The most common types of shuttering used in house building are timber and steel plates Generally wooden shuttering is cheap and easily available. This is one of the oldest method of shuttering. Wooden shuttering looks cheaper but we recommend steel plates as wooden shuttering produces uneven surfaces resulting in usage of more material in plastering and if you are not careful, it can effect or compromise strength of concrete. Steel shuttering is also better than wooden shuttering because it is water tight which enhances the strength of concrete. Also as already pointed out, the thickness of plaster is also lesser if steel shuttering is used

      IX.            Lay the Iron Net
The iron net is laid before laying of linter
      
      X.           
Installation of pipes on iron net for electrical wiring
Electrician work starts before concreting of roof. Electrician spreads the pipes for electrical wiring over the iron net according to the electrical design

     XI.            Laying of Linter (Mixture of cement, sand and bajri) – RCC roof
RCC means reinforced cement concrete. This is the most important part of construction in which cement, sand and bajri is laid on the net of steel. Most commonly used ratio of this mixture is 1:2:4. It means one part of cement, two parts of fine sand and 4 parts of bajri

     XII.            Installation of pipes in walls for electrical wiring
Once linter completely gets dry and shuttering is removed, electrician installs the pipes in the walls as per drawings

     XIII.            Plumbing works
Plumber installs all the pipes in walls and floor for drainage and sewerage. He should keep the points for all the fittings according to the drawings. In most of the cases, one pipe is used for clean and dirty water but bye laws of some societies do not allow you to do that and you have to have two different pipes each for clean and dirty water. It increases the plumbing cost but has certain advantages for future use

    XIV.            Cementing the floor and ramp
To cement the floor, rora (small parts of bricks) is spread in all parts of the house and mixture of cement, sand and bajri is poured over it to prepare the floor for tile work. One thing to do before cementing the floor is to go for the second round of termite spray to protect your house completely from termite

    XV.            Plaster of inside walls and roofs
Plaster (mixture of cement and sand) applies on inner walls and roofs. A good ratio of plaster is 1:3 (one part of cement and three parts of sand). Smoother the plaster, better will be the strength and outlook of the house.
Now a days ceiling work is in demand and in fashion. If you are going for false ceiling, there is no need to plaster the roof otherwise it will increase your costs

    XVI.            Laying of electrical wires and installation of main DB (distribution box)
Now electrician inserts the wires in the pipes and prepares the distribution box (DB) by placing all the switches and main breakers. The important thing to remember while selecting cables/ wires is the level of resistivity.

   XVII.            Plaster of outside structure
Plaster of outside structure including boundary wall starts and with the completion of this step, grey structure gets completed

    does placement of washroom accessories like basin, commode and shower etc. comes in gray structure or in finishing phase ? Just clarify the placement of all doors, main gate, basic washroom accessories like basin, commode and shower etc. comes in gray structure or not ? secondly how much percent cost comes on gray structure out of total cost? regards
