Modern Underpinning Development Methods And Typical Examples

bjects. The object of the series is to place in the hands of the practising engineer all the essential information regarding the particular subject in which he may be inter- ested. Extraneous topics are excluded, and the contents of each book are confined to the field indicated by its title. It has been considered advisable to make these books man- uals of practice, rather than theoretical discussions of the subjects treated. The theory is fully discussed in text-books, hence the engineer who has previously mastered it there is, as a rule, more interested in the practice. The Wiley Engineering Series therefore will present the most approved practice, with only such theoretical discussion as may be necessary to elucidate such practice.
