SOP
SOP turns up in 2 fields: surveying, shop slang. Here is what it means to the people in each one.
SOP in surveying
The abbreviation for setting-out point, a specific coordinate marked on the ground for construction.
A setting-out point is a physical mark established by a surveyor to guide builders and contractors. These points transfer design coordinates from digital models onto the actual site. Surveyors place them at critical locations like building corners, column centerlines, or offset lines so construction aligns exactly with the engineering plans.
