Surveying is not short of guidance. It is short of guidance written by someone who was on a roof last week — the kind that tells you where an instrument misleads, not just how to switch it on.
- 01
OBSERVERead what is actually there.
Age, construction, exposure, alterations and the pattern of visible evidence — before any instrument comes out of the bag.
- 02
REASONSeparate symptom from cause.
The building is considered as a system, with limitations and uncertainty stated honestly rather than hidden behind a rating.
- 03
RECORDWrite it so it holds.
What you saw, what you could not see, and why the rating follows from the evidence — in wording that reads the same on the next job.
