Steel Erection RAMS Guide for UK Contractors
Steel erection RAMS must address lifting plans, temporary stability during erection, bolting and connection sequences, exclusion zones, MEWP use, and weather restrictions. Falls during erection and steel collapse due to inadequate temporary stability are the primary fatal risk scenarios.
Key Topics in a Steel Erection RAMS
- Lifting plan
- Every crane or MEWP lift during steel erection must be covered by a lift plan. The lift plan must be prepared by the Appointed Person (AP), a competent person under LOLER 1998. The RAMS must reference the lifting plan and confirm it covers each lift type. Lift plans are distinct documents but must be referenced in the RAMS.
- Temporary stability
- Structural steelwork can be unstable between connection stages. The structural engineer must confirm the sequence that maintains stability, including minimum connection requirements before releasing crane. The RAMS must reference the structural engineer’s temporary stability note and state the minimum connections required before crane release.
- Bolting and connection
- Bolts must be tightened to the specified torque or snug-tight criteria. The RAMS must address the bolting method, inspection requirements, and whether any high-strength friction grip (HSFG) bolts require specialist procedures. Welded connections require a separate hot works permit.
- Exclusion zones
- A full exclusion zone must be established beneath the erection area for the duration of lifting operations. Size must account for the maximum lift radius plus a collapse zone. Barriers, signage, and banksman required.
- Weather limits
- Crane operations above specified wind speeds must be suspended. Steel erection at height must stop in conditions that impair grip or stability. The RAMS must state the specific wind speed limits and who has authority to stop work.
