Default Surveying for construction

The device you saw mounted atop a yellow tripod at a construction site is most probably a theodolite or a transit, both of which are used to determine boundary lines when sighted and aligned to a marker post. The tripods used are typically basic units designed for this purpose and not photographic tripods.
