Survey Marks: are those marks placed by a surveyor to help define the boundaries or corners of a nominated parcel of land. A surveyors field notes define those marks placed in the course of the survey. Corners are usually marked by white painted wooden pegs of dimension 80mm x 80mm by a length of 380mm. However, in some circumstances they can also be defined by ‘Spring Head’ nails (SHs) [see photo to the right], steel ‘star fence droppers’ (stars), steel ‘bridge spikes’ (spike or spk) or a rod or steel bar (bar). Generally if the need arises any method of marking is undertaken and the form noted in the field notes. Surveyors often use brightly coloured ‘flagging’ tape to help identify survey matters of significance, as shown around this SH Nail in OPost. The second picture shows a Black Steel Star at the base of a silver fence dropper; the black steel star is the survey mark.

To make matters more confusing, surveyors use the same type of marks as ‘arbitrary’ survey stations and reference marks. They have a definite relationship to the boundaries as defined in the surveyors field notes but without the surveyors ‘skill’ are of little use to the layperson. The trap is if they are mistaken for a boundary corner mark. Survey Marks are also placed as 'Control' for Detail and Engineering type surveys.

SIMPLY:

Any type of mark may have been used to define your boundary corner. Be aware that a mark found may be a reference mark and not a corner. Surveyors field notes define the mark used.
