Many builders make the mistake of assuming the embankment of an excavation will stand up or not be subjected to subsidence and many builders have been cought with expensive remedial repair works as a result of landslips or the foundation settlement of adjoining buildings.
Sand is particularly deceptive and unless a good understanding of angles of friction, slip circles and the effects of any nearby structure imposing surcharge loads on the excavated batter the risk of personal and property safety is a real danger.
An important point to remember is that it is far easier and cheaper to address a potential problem by way of shoring or soil stabilization prior to any excavation than it is to conduct remedial ground works on a half excavated site which is ready to collapse.
