An essential reference for both students and practicing engineers. Das succeeds in making foundation engineering understandable while maintaining technical rigor. The book's strength lies in its practical approach to design problems. What truly distinguishes this book is Das's ability to make complex geotechnical concepts accessible without oversimplification. The inclusion of SI and Imperial units throughout is particularly helpful for international practice. Minor Drawbacks: 1.Some numerical examples could use updating 2.Could include more on seismic design 3.Limited coverage of ground improvement techniques but it should be noted that Das has already written a book dedicated to soil improvement, and this book might be the perfect resource for me.
