Scaffolding on a higher-risk building: what changes for the subcontractor

Work on a higher-risk building goes through the Building Safety Regulator for building control approval rather than through a local authority or approved inspector. Most of the commentary on that is aimed at principal contractors and designers, which leaves specialist subcontractors to work out their own position.

For a scaffolding contractor the position is narrower than the headlines and sharper than it looks.

Three things that actually change

• –Competence is explicit rather than assumed. The regime expects dutyholders to be able to demonstrate it, which pushes down the chain as a question about your people and your records rather than about your firm's reputation.
• –Change is controlled. A scaffold that is adapted on site is a change, and on this kind of job the route for approving it is not an informal conversation with the site manager.
• –Information has to survive the job. What you produce — design, handover, inspections, adaptations — is expected to be capturable and transferable rather than filed in your own system and forgotten.

None of that is a new duty invented by the regime. It is the existing duty, asked for in a form that can be audited.

Adaptations are the exposure

Scaffolding is adapted constantly, and the industry's normal handling of that — adapt, re-inspect, re-tag, log it — is sound but informal at the edges.

On a higher-risk building the question becomes whether your record of an adaptation would stand on its own months later, to somebody who was not there. That is a higher bar than a tag and a line in a book, and it is the same bar keeping design and site in step was already trying to meet.

Competence, as a thing you have to show

Every scaffolding contractor says its people are competent, and in this trade it is usually true — the card scheme and the apprenticeship route do real work. The regime asks for something slightly different: not whether they are, but whether you can demonstrate it on request.

• –Cards per operative, with the level and the expiry, for the work they are actually doing rather than the work they were trained for.
• –Evidence the supervisor's competence matches the complexity of the structure, which is a judgement somebody should have made and recorded.
• –Where you use subcontract labour, the same evidence for them, held by you rather than promised by the supplier.
• –A design produced by somebody whose competence to produce it is established, which matters more as soon as a scaffold stops being TG20 compliant.

The failure mode is not an incompetent gang. It is a competent gang whose evidence is in four systems, one of which is a filing cabinet in a yard, when the request arrives with a deadline on it.

What to have ready

• –CISRS records per operative, current, with the card expiry visible rather than filed.
• –The design, the handover certificate, and every adaptation, linked to each other rather than stored separately.
• –Inspection records that reference the configuration they were carried out on. An inspection of a scaffold that has since changed is a record of something that no longer exists.
• –A named person for change, on your side, who can be asked about an adaptation two years later.
• –The same bundle you would want for an audit, assembled as the job runs rather than retrospectively.

The honest summary is that a scaffolding contractor already doing all of that properly will find the regime adds paperwork rather than difficulty. One relying on the tag and the inspector's memory will find it exposes something that was always a weakness.
