This document is intended to walk architecture and engineering students step-by-step through the basics of how excavation actually occurs in urban contexts, emphasizing safety, sequencing, and organized planning. It will also describe how survey control, virtual 3D coordination, and jobsite safety site rules manifest themselves into daily field routines.
