ABSTRACT
Before commencing any study of the principles of the planning of construction methods, it is essential that the meaning of a number of words and phrases are defined and understood as they will be used in this book. In the so-called world of information technology, it is remarkable that specific words seem to be capable of endless meanings, and as a result can readily be misinterpreted by different people. It is hoped that the definitions and meanings given here will make some contribution to stabilizing the meanings of words and phrases associated with the planning of construction activities.
