| Standards (vertical posts) | Carry scaffold loads down to the base and provide connection points for ledgers and transoms. | Consistent tube dimensions, straight members, securely attached lower cups, and compatible node spacing throughout the system. | Check for dents, cracks, corrosion, bent ends, loose cups, and clear identification of the system and its rated components. |
| Ledgers and transoms | Connect standards, define scaffold bays, and support the working-platform arrangement. | Correct lengths for the planned bay layout; intact end blades that seat fully in the cups; no visible deformation or damaged welds. | Confirm that each blade fits its matching cup and that the connection locks as intended. Do not mix incompatible systems. |
| Cup-and-blade connections | Create the node connections between standards and horizontal members. | Cups should move and secure as designed, with no cracks, severe wear, distortion, or obstructing debris. | Assemble a sample bay before use. Check that all required members seat fully and that the locking cups cannot be left partially engaged. |
| Diagonal bracing | Helps resist sway and maintain the scaffold’s stability. | Braces and their fittings must match the bay geometry and be included wherever required by the design or applicable guidance. | Verify brace locations against the approved scaffold design; check that connections are secure and members are not bent or damaged. |
| Base plates and adjustable base jacks | Transfer loads to the supporting surface and allow limited leveling at the base. | Sound bearing plates, straight threaded stems, usable adjustment nuts, and adequate bearing on suitable sole boards or foundations. | Check ground capacity, drainage, and level. Keep jack extension within the system designer’s limits and never use loose packing as a substitute for proper support. |
| Working platforms and access | Provide the working surface and a safe route onto and through the scaffold. | Platforms should be suitable for the intended duty, properly supported, secured against displacement, and arranged to avoid unsafe gaps. | Check platform condition, support, access openings, and safe ladder or stair access. Keep platforms clear of excess materials. |
| Guardrails, toe boards, and edge protection | Help prevent falls of people and materials from exposed platform edges. | Use compatible components and install edge protection at locations required by regulations, the design, and the work conditions. | Inspect every exposed platform edge and access opening. Confirm components are secure and positioned according to local requirements. |
| Ties and anchorage | Connect the scaffold to a suitable supporting structure to help control movement and overturning. | Locations, tie pattern, and anchor capacity should follow the scaffold design and account for site conditions such as wind and sheeting. | Confirm that anchors are installed in sound material and that ties are not removed or altered without approval from a competent person. |
| Load rating and design | Define the intended scaffold duty and ensure the arrangement can safely support its expected loads. | Use a design or configuration appropriate to the site, height, bay layout, access, loading, ground conditions, and applicable local standards. | For context, EN 12811-1 defines working-area load classes from 1 to 6, with uniformly distributed loads from 0.75 to 6.0 kN/m². The correct class must be selected for the task. |
| Material condition and traceability | Support consistent assembly, inspection, maintenance, and replacement of components. | Prefer components with documented material specifications, manufacturing quality controls, inspection guidance, and clear system identification. | Quarantine components with cracks, significant corrosion, bent members, damaged threads, loose welds, or uncertain compatibility until assessed. |
