Measurement of Occupation
Why is occupation important?



Indication of possession
Some indication of extent of ownership
and therefore boundaries (if fencing
related to original survey marks)
In absence of other original marks, it
may form the basis of reinstatement of
property boundaries, particularly in
older or rural areas.
Occupation

Occupation in 3 main categories:



Round Fence Post (RFP)
Square Fence Post (SFP)
Walls (when part of structure)
Fence Descriptions

Materials including posts


Age


Old (20+ yrs), Recent (1-5 yrs), New (1yr)
Condition


Netting, Ringlock, 4 Barbs, ornamental
Leaning, Rotted out, Remains
Height

High, Low
Walls



To avoid confusion, only use ‘wall’ when
part of structure
Eg NW Cnr Brick Fence or NW Cnr Brick
Wall (if part of structure)
Exception is retaining walls which
should be fully described
Fence Posts


Corner posts most important
Material and Shape


Age


GIFPost, RFP, SFP, Steel FP
Old (20+ yrs), Recent (1-5 yrs), New (1yr)
Condition

Remains, Leaning, Burnt, Butt
Measurement to Occupation

On front boundary





RFP - Centre of post (Cen RFP)
SFP - Centre of road side face of post (Cen Face
SFP)
Corner Lots - Corner of post corresponding with
corner of section
Walls - Road side face or corner of the wall and
specify the corner measured (NE Cnr Brick Wall)
On rear & side boundary

Measure to centre of occupation




Consider recording the size of post to
aid reinstatement
Check for verticality
If not vertical, ‘plumb’ the post
How?


Occupation referenced to main lines of the
survey
Only used for corner marks and occupation
Not used for reference marks such as
Reference Trees, PSMs, Iron Pins, etc
Mainly specific to Queensland
Beware skewed lines (not perpendicular)
If in doubt, show a bearing and distance
