摘要

This invention describes a method of locating a foundation member comprising drilling a first hole (13), drilling a second hole (13) alongside the first hole (13) so that it overlaps with the first hole (13), drilling successive holes (13) that each overlap with the previous hole (13) and drilling all of the holes (13) along a set path to form a slot (14) and locating and fixing a foundation member (10) within the slot. The invention provides an alternative means of locating a foundation member by comparison to excavation processes.
