Question

CPRF stands for:

(a) Combined Plain Round Foundation

(b) Connected Pile Round Foundation

(c) Combined Pile Raft Foundation

(d) Corrosion Proof Raft Foundation

I had been asked this question during an interview.

I'd like to ask this question from Foundation topic in portion Building Construction of Basic Civil Engineering

Answer 1

Right answer is (c) Combined Pile Raft Foundation

To explain I would say: CPRF uses the combination of pile and raft foundation as the name suggests.  It is used as a foundation for high rise buildings. It is more powerful, strong, load bearing, safe than raft or pile when used.
