Auditors check three things: every scaffold sits on a register with a number, a drawing reference and a current tag; the inspection records match the tags on site; and the people who erected and inspected hold current competence evidence. Build that file before mobilisation, then walk ten scaffolds against it yourself.
What an auditor asks for
| Question the auditor asks | Evidence to have ready | Where the requirement comes from |
|---|---|---|
| Which scaffolds exist, and who owns each? | Scaffold register with number, location, user, erection date | Scaffold-control procedures such as EXPRO (KSA) use unique scaffold numbers and tags |
| Is each one inspected on time? | Inspection records matching tag dates; no expired tags | Inspection at intervals not exceeding 7 days (EXPRO procedure); records kept on site (OSHJ-CoP-23) |
| Was it built to a design? | Drawing or standard configuration reference; engineer design where required | OSHJ-CoP-23 calls for a qualified scaffold engineer above 10 m |
| Are the people competent? | Cards and certificates with expiry dates, supervisor and inspector appointments | OSHJ-CoP-23 defines competence by training, knowledge, experience and skills |
| Is anyone checking the system itself? | Internal audit records | The EXPRO procedure lists quarterly HSE audits |
Steps to build the audit file
- Export the scaffold register and remove duplicates and dead numbers.
- Match every live scaffold to a tag on site; list mismatches and fix them first.
- Pull the last inspection record for each scaffold and check date, inspector, and defects closed.
- Collect competence evidence for every erector, supervisor and inspector. Note expiry dates: one UK vendor article (Zigaflow, August 2026) says CISRS cards run on a five-year cycle; check the card issuer's own rule.
- Attach the design reference for every cantilever, hanging, loading bay and scaffold above the engineer-design threshold of your site rules.
- Do a self-audit walk of ten scaffolds, chosen by risk, and write what you find the same day.
- Review scaffolds that have stood a long time. A Becht article on turnaround scaffolding (September 2021) suggests reviewing any scaffold still in place after 90 days and reports that questioning access requests typically cut scaffold volume by about 30%.
What we deliberately do not repeat
One vendor page publishes scaffold pre-build percentages by height band and productivity claims, but states no data source. Treat such numbers as marketing until a client's own turnaround procedure confirms them.
Common mistakes on site
- Registers that list scaffolds already dismantled, so the auditor finds ghost numbers.
- Tags updated in the field but not in the register, or the reverse.
- Competence evidence kept by the HR office, not available at the gate.
- Defects closed on the ground but not re-inspected and re-tagged.
- No record of who may sign a tag, so signatures cannot be matched to appointments.

Questions
How long before mobilisation should I start preparing?
Start when the scaffold register is first drawn up. The documents we read give no fixed lead time, and the one vendor page that does cites no data.
Which records must be on site?
OSHJ-CoP-23 requires inspection records to be kept on site. A UK vendor article suggests keeping them until the next inspection and ideally for three years after dismantling; check your contract and client rules.
What does an inspection record contain?
In the UK, location, date and time, defects, action taken, further action and the inspector's name and role. Add scaffold number and tag colour.
Can the Field App hold the register?
Yes, the free AL-YASSIN Field App keeps an inspection and tag register and works offline, as stated on its page.
