One two three ..and…… start

Dear reader , 
In the very first post , we saw the overview of what is happening in the neighborhood plot.
Right ? From the distance , we just saw that some thing was happening inside the enclosed boundary.
Today let us take a micro view of all that takes place during the construction.
Let us follow the actual sequence of the activities being taken up right from start to finish;
rather even before starting the actual construction.
Basic idea is to have an insiders perspective about the entire construction.

Overview :

There are 4 phases of construction:

1.Planning phase
2.Pre construction phase
3.Actual construction phase

    3.A:  Below the Plinth
    3.B: Above the Plinth
4.Handing over phase

1.The Planning phase :

This is most crucial phase in the entire project. The importance of planning cannot be over emphasized.

Many crucial decisions are being taken during this phase.
