Abstract:
The two parts of the building are the superstructure and substructure. Carries all types of
loads on the building to the foundation carrying superstructure and substructure. Raft
and pile foundations are becoming increasingly popular in the construction of
multistory buildings, especially when the load-bearing capacity of the foundation is
low and the column load is very high. This thesis paper discusses the cost of laying
the foundation of concrete buildings and which foundation is more affordable.
There are mainly two types of foundation discussed here, where the bearing capacity
of the soil and the value of SPT value N is assumed to be the same for the two
foundations. These two types of foundations are raft and pile foundations, where raft
and pile foundations are relatively heavy and expensive structures. Many types of
research papers have come out in the days of raft and pile foundation design but no
one has discussed which foundation building is more affordable and long-lasting.
Depending on all the circumstances and surroundings, raft foundation cannot be used
in some buildings but pile raft foundation can be used where the cost of raft
foundation becomes more expensive than pile foundation.
Based on all these circumstances, it can be said that the cost of a foundation will be
more or less determined by where the building is being erected. However, in most
cases, it is more affordable to set up a raft foundation than a pile foundation.
