Erecting and dismantling pedestrian access or roof saddle in the workplace
This subtopic covers the practical skills and knowledge required to safely erect and dismantle pedestrian access scaffolds (such as temporary footbridges or stair towers) and roof saddles (scaffolds spanning roof ridges) in compliance with current industry standards like TG20:21 and relevant legislation. Learners must demonstrate the ability to interpret work instructions, select appropriate resources, implement safe working practices, and complete the work within contractual and specification requirements while minimising risk to personnel and the environment.
Assessment criteria
Topic Overview
The GQA Level 2 NVQ in Accessing Operations and Rigging (Construction) – Scaffolding is a competence-based qualification designed for individuals working in the scaffolding industry. It covers the skills and knowledge required to safely erect, alter, and dismantle basic scaffolding structures, including independent tied scaffolds, birdcage scaffolds, and mobile towers. This qualification is essential for those seeking to become competent scaffolders and is recognised by the Construction Industry Scaffolders Record Scheme (CISRS) as part of the pathway to a Scaffolder Card.
This NVQ focuses on practical, on-the-job performance, assessing your ability to work safely and efficiently in real construction environments. You will learn to interpret loadings, select appropriate materials, and use safe systems of work such as method statements and risk assessments. The qualification also covers communication, team working, and the correct use of personal protective equipment (PPE). Achieving this NVQ demonstrates that you can work to industry standards and is a key step towards career progression in scaffolding.
Within the broader context of Construction & Building Services, scaffolding is a critical trade that enables safe access for other construction activities. This qualification sits alongside other NVQs in construction, such as those for bricklaying or carpentry, and is part of the suite of qualifications offered by GQA Qualifications Limited. It is suitable for apprentices, experienced workers seeking formal recognition, and those looking to specialise in advanced scaffolding or supervisory roles.
Key Concepts
Core ideas you must understand for this topic
- →Safe erection and dismantling: Understanding the sequence of assembly, correct use of fittings (e.g., double couplers, swivels), and ensuring stability at all times.
- →Load calculations: Knowing how to determine safe working loads (SWL) for scaffolds, including dead loads (scaffold weight) and live loads (workers, materials).
- →Tying and bracing: Using effective ties (e.g., through ties, reveal ties) and bracing (longitudinal, transverse) to prevent scaffold collapse.
- →Inspection and handover: Conducting pre-use inspections, completing the SG4:22 inspection checklist, and formally handing over the scaffold to the user.
- →Working at height regulations: Complying with the Work at Height Regulations 2005, including fall protection measures like guardrails, toe boards, and safety harnesses.
Learning Objectives
What you need to know and understand
- Interpret the given information relating to the work and resources when erecting and dismantling pedestrian access lift or roof saddle.Know how to comply with relevant legislation and official guidance when erecting and dismantling pedestrian access lift or roof saddle.Maintain safe and healthy working practices when erecting and dismantling pedestrian access lift or roof saddle.Select the required quantity and quality of resources for the methods of work to erect and dismantle pedestrian access lift or roof saddle.Minimise the risk of damage to the work and surrounding area when erecting and dismantling pedestrian access lift or roof saddle.Complete the work within the allocated time when erecting and dismantling pedestrian access lift or roof saddle.Comply with the given contract information to erect and dismantle pedestrian access lift or roof saddle to the required specification.
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating accurate interpretation of given information, including dimensions, load capacities, and foundation requirements from technical drawings or work specifications.
- Evidence must show compliance with key health and safety legislation, such as the Work at Height Regulations, through correct use of guardrails, toe boards, and safe ladder access throughout the erection and dismantling process.
- Assessors should look for the selection of undamaged, compatible components (e.g., tubes, fittings, boards) in correct quantities, with rejection of defective materials to ensure structural integrity.
- Credit should be given for protecting the surrounding area and structure, including the use of barriers, exclusion zones, and careful handling to prevent damage to the building fabric or public during operations.
Assessment Guidance
Guidance for achieving higher grades
- 💡For portfolio evidence, include photographs showing full scaffold with proprietary system safety features (e.g., advanced guardrail systems) and close-ups of connections to demonstrate compliance.
- 💡Ensure your risk assessment and method statement (RAMS) are job-specific, signed, and referenced in your evidence write-up to show integration of safety planning.
- 💡When providing witness testimony, brief your witness to comment on your adherence to time constraints and proactive minimisation of disruption—this addresses time and contract compliance criteria.
- 💡Always refer to the latest industry guidance, such as NASC (National Access and Scaffolding Confederation) documents like TG20:21 for tube and fitting scaffolds. Examiners look for evidence that you are up-to-date with current best practice.
- 💡In your portfolio, focus on demonstrating your understanding of why you do things, not just how. For example, explain why you chose a particular tie configuration or bracing pattern – this shows deeper competence.
- 💡Pay attention to the detail in your risk assessments and method statements. Examiners will check that you can identify specific hazards (e.g., overhead power lines, fragile roofs) and control measures (e.g., exclusion zones, netting).
Common Mistakes
Common errors to avoid in your coursework
- Failing to conduct or document a thorough ground condition assessment before erection, leading to unstable foundations or inadequate base plates/sole boards.
- Omission of critical bracing or ties in roof saddle scaffolds, compromising lateral stability under wind or dynamic loads.
- Not securing scaffold boards properly or leaving gaps between boards, creating trip hazards or potential for falling objects.
- Dismantling in the wrong sequence (e.g., removing ties or guardrails too early), which can lead to partial collapse or unsafe access during teardown.
- Misconception: 'All scaffolds need to be tied every 4 metres vertically.' Correction: Tying intervals depend on the scaffold type and load; for independent scaffolds, ties are typically required every 2 bays horizontally and 4 metres vertically, but this can vary based on wind loading and configuration.
- Misconception: 'You can use any type of coupler for any connection.' Correction: Couplers are specific to their purpose – right-angle couplers for load-bearing connections, swivel couplers for angled connections, and sleeve couplers for extending tubes. Using the wrong coupler can compromise structural integrity.
- Misconception: 'A scaffold is safe as long as it looks stable.' Correction: Visual stability is not enough; scaffolds must be designed and erected to calculated loadings, with proper bracing and ties. An apparently stable scaffold can collapse under wind or uneven loading.
