Thanks Guys.
I am not much familier with either Metcalf & Eddy editions (3rd ed. or 4th ed.) did use both a little bit few months back when I was studying. (dont recollect anything now)
I am taking the Das Geotech book so looks like Coduto may be good for foundation.
I have room for one from each of the list
Metcalf & Eddy
3rd ed. or
4th ed.
Principles of Foundation Engineering - Das 1992 or
Foundation Design - Coduto 1995
which one should I take?
