Thank you Sebastien. 
I am studying the following links.

My goal is that I have .txt file storing building footprints,
Firstly, I have to read this file and store the points in such a way that it should be Topologically Consistent.
Then I have to use that Topologically consistent dataset to extrude Buildings which should be topologically as well geometrically consistent.

Please I'm looking forward for your help.

Thank you!

What is the goal and the desired output?

I mean, it looks like there is no difficulty if your footprints
do not intersect.

If this is just a matter of storing data, you can use the Polyhedron_3
class:

with the incremental builder:
