A scaffold handed over in March is rarely the same scaffold in June. A lift goes on, a bay comes out to let a delivery through, a section is sheeted because the trade underneath got tired of the weather. Each one is a small, reasonable request. Together they are the reason nobody can say what the structure was built to.
Why the informal ones are the dangerous ones
An adaptation that goes through the office gets looked at: does it still sit inside the compliance sheet, does the tie pattern still work, does the loading class change, does the client need a new certificate. An adaptation done as a favour on a Friday gets none of that. The scaffold may well be fine. The evidence that it is fine has quietly disappeared.
What a usable adaptation record contains
- Which structure — not which site, which structure.
- What changed, in the terms the design uses: lifts, bays, ties, cladding, loading.
- Who asked for it, and who carried it out.
- Whether the original design still covers it, or whether it went back for sign-off.
- The new tag status and whether a fresh handover was issued.
None of that is onerous when it is a form on a phone at the point the work happens. All of it is impossible to reconstruct a year later, which is exactly when somebody asks.
Key takeaways
- Unauthorised alterations are the most common way a structure leaves its design.
- Record the change against the structure, in the same terms the design uses.
- Every adaptation should answer: does the existing design still cover this?
- A record captured at the point of work costs minutes; a reconstruction costs days.
