Abstract

Recent regulations call for pre-blast surveys of residences within one-half mile of blasting. This paper discusses factors to note during pre-blast surveys, presents data collection forms and discusses the importance of photographic technique in recording cracks (both present and previously patched). Side light (almost parallel to the wall) best reveals cracks.
