Planning, Risk Assessment, and Method Statements
Planning starts with a risk assessment that identifies hazards (falls from height, falling objects, instability, weather, electrical, manual handling, public interface) and controls them via the hierarchy. The method statement then translates controls into a sequenced, resourced plan: scope, sequence, plant, access, edge protection, exclusion zones, emergency arrangements, and competence requirements. For advanced work, a design brief feeds the designer, and the erection method statement must reflect the design assumptions (e.g. tie positions, bracing, load class).
Traps: treating the risk assessment as a paper exercise disconnected from the method statement; omitting the public/third-party interface; forgetting weather limits (wind speed thresholds for erection and for sheeting); and failing to plan for rescue (a fall arrest plan without rescue is incomplete). Also expect questions on permit-to-work and on the need to review and revise when conditions change.
Worked example: For a scaffold adjacent to a public footpath, the risk assessment identifies falling objects; controls include a covered walkway, debris netting, toe boards, and a exclusion zone with signage. The method statement sequences erection away from the public side, defines the netting installation point, and names the supervisor who signs off the exclusion zone before work starts.
