Comparison of Cost and Suitability of Using Raft and Pile Foundation for Building

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.
