UK construction-safety guidance by the Riskora Editorial Team
Producing a proper risk assessment for steel erection is not optional — it is a legal and practical requirement for construction work in the UK. Whether you are a sole trader or managing a multi-phase project, documented risk management protects your workers, satisfies clients, and keeps you on the right side of HSE enforcement.

The Management of Health and Safety at Work Regulations 1999 require employers to carry out a suitable and sufficient risk assessment for steel erection before operations start. Self-employed workers carrying out construction activities must also comply.
A construction contractor in UK needs to produce a risk assessment for steel erection before starting work next week. The client has requested professional documentation as a condition of site access. Using Riskora, they select the relevant trade preset, review pre-populated hazards, adjust controls for their specific site, and generate a professional risk assessment in under 5 minutes — ready for review and sign-off.
The Work at Height Regulations 2005 hierarchy applies directly: use a MEWP so no one is exposed to the fall, before resorting to arrest systems. Alongside it, BS 5975 requires temporary works — which includes the erection sequence and bracing — to be designed and checked under a temporary works coordinator, and LOLER 1998 requires every lift to be planned by a competent person.

Steel erection is one of the few activities where the temporary condition is more dangerous than the finished one — the frame is least stable exactly when people are climbing it. Documentation that describes the finished structure and the crane, but not the erection sequence and the temporary bracing that keeps the frame standing between them, is describing the wrong thing.
| Hazard | Control measure |
|---|---|
| Falls from the steel frame during connecting and bolting | MEWP access as the primary method so connectors work from a platform rather than the steel; where access from the steel is unavoidable, a fall-arrest system with designed anchor points, twin lanyards and a written rescue plan. |
| Collapse of the partially erected frame before it is stable | Erection sequence and temporary bracing designed by the temporary works engineer, guys and props installed as the frame rises, and no release of the crane from a member until it is stable in its own right. |
| Dropped bolts, tools and small components | Tool tethers for everything used at height, bolt bags rather than pockets, exclusion zone below the erection area, and no simultaneous work beneath the frame. |
| Lifting failures — slinging, load control and crane stability | Lift plan by an Appointed Person, crane on assessed ground with outrigger loads calculated, certified accessories checked before each shift, tag lines on every load, and a trained slinger-signaller in sole control of the lift. |
| Wind loading on large members and decking | Stated maximum wind speed for lifting (commonly 20 mph for large-surface-area members), anemometer reading recorded before each lift, and decking bundles strapped and secured whenever they are not being fixed. |
| Metal decking laid over open floors before it is fixed | Decking laid to the designed sequence and fixed progressively, edge protection installed as the deck advances, and no walking on unfixed sheets. |
Only after MEWP access has been genuinely discounted. The Work at Height Regulations 2005 put collective and platform-based access above personal fall protection, so documentation that goes straight to harnesses without explaining why a platform is impracticable is inverting the hierarchy.
The temporary works engineer, checked under the BS 5975 procedural control regime and accepted by the temporary works coordinator. The steelwork contractor cannot decide the sequence on site, because the sequence is what keeps the incomplete frame standing.
A plan and equipment capable of recovering a suspended person within minutes, because suspension trauma develops fast. That means a named rescue method, the equipment on site, and trained rescuers present during the work — not a call to the emergency services.
Select your trade, pick your hazards, and generate a structured document — no training required.
