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

Netting, Ringlock, 4 Barbs, ornamental Age

Old (20+ yrs), Recent (1-5 yrs), New (1yr)

Condition 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

GIFPost, RFP, SFP, Steel FP Age

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?
