What is a site audit?
A site audit is a structured inspection of cleaning quality against the specification, scored consistently so results can be compared between visits and between sites.

</figure>Its value is in being repeatable. A score means nothing on its own and everything as a trend, so the same criteria applied the same way month after month is worth more than a more detailed form used inconsistently.
Joint audits with the client resolve most disputes before they start. A score both parties arrived at together is very hard to argue with afterwards, and the conversation during the walk is usually more useful than the number.
Findings need to behave like actions: owner, date, evidence of closure. Audits that produce scores without follow-up create a record of decline rather than a mechanism against it.
In practice
Two supervisors auditing the same corridor in the same week.
One scores it well, one scores it poorly. Neither is wrong, because neither was scoring against anything fixed — they were scoring against their own expectations.
An audit is only comparable if every line references the specification, and if the scoring basis is written on the sheet so a change to it is visible.
The client notices the inconsistency long before the contractor admits it.
What goes wrong in practice
- Scores recorded with no actions raised, so the audit documents a problem without addressing it.
- Different auditors scoring differently, which destroys the trend the score exists to show.
- Audits always at the same time on the same day, which measures a prepared building.
- Photographs taken and never attached to the finding they evidence.
