Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for clear demonstration of reading and interpreting conservation-specific documentation (e.g., schedules of work, heritage statements).
- Look for evidence of compliance with legislation such as CDM 2015, COSHH, and any listed building consent conditions attached to the project.
- Assessors to observe safe handling of tools, correct use of PPE, and adequate work at height precautions including scaffolding or platforms.
- Candidate must justify material selection, citing timber grading, moisture content, and species compatibility with the original fabric.
- Credit for methodical approach to protecting surrounding historic fabric with dust sheets, temporary supports, and careful material handling.
- Evidence of time management expected, such as a daily work log showing planned versus actual task completion.
- Final inspection must confirm that restored timberwork aligns precisely with contract documents, with any variations formally approved.
- Award credit for accurately interpreting contract documents, specifications, and technical drawings before commencing conservation or restoration tasks.
- Credit clear demonstration of selecting and justifying repair methods, such as splicing or resin repairs, based on structural assessment and conservation requirements.
- Credit maintaining a safe and tidy work area, including correct use of PPE, dust extraction, and adherence to health and safety legislation like COSHH and CDM.
- Credit producing or updating condition reports, recording dimensions, timber species, defects, and treatments applied for client or conservation officer sign-off.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always cross-reference the specification with the conservation plan; any discrepancies must be flagged before procurement or work begins.
- 💡Document every decision: photographs, material datasheets, and written rationale for any departure from original design.
- 💡Prepare a thorough risk assessment that specifically addresses the fragile nature of aged timber and adjacent historic structures.
- 💡When selecting replacement timber, demonstrate understanding of seasoning, natural durability, and grain matching to the original species.
- 💡Plan your work sequence to allow for drying times of adhesives, mortars, or finishes, and potential delays in sourcing specialist materials.
- 💡During observed assessment, narrate your actions to the assessor, explaining compliance with conservation principles and contract requirements.
- 💡For work-based evidence, include annotated photographs and witness statements that explicitly link your actions to the performance criteria.
- 💡Always cross-reference your work with current legislation and industry standards (e.g., BS 7913 for conservation) within your written reports.
- 💡When faced with unforeseen conditions during a task, document your problem-solving process and communication with supervisors or conservation advisors.
- 💡Use clear, methodical explanations in write-ups: describe not only what you did but why, especially when choosing traditional versus modern repair techniques.
- 💡Tip 1: Focus on accuracy and finish. Examiners look for tight joints, square cuts, and smooth surfaces. Use a sharp pencil and a try square to mark out precisely, and sand edges to remove splinters before assembly.
- 💡Tip 2: Demonstrate your knowledge of health and safety throughout the assessment. For example, when using a circular saw, explain the importance of checking the guard and using a push stick. This shows you are a responsible worker.
- 💡Tip 3: Practice interpreting technical drawings under timed conditions. In the assessment, you may need to work from a drawing to cut and assemble a component. Familiarize yourself with common symbols and abbreviations to save time.
Common Mistakes
Common errors to avoid in your coursework
- Misinterpreting heritage conservation specifications, leading to use of inappropriate materials or modern techniques that harm authenticity.
- Failing to check for protected species (e.g., bats) or nesting birds before commencing work, which can lead to legal breaches and project stoppages.
- Neglecting to obtain necessary approvals such as listed building consent prior to altering historic fabric.
- Overlooking moisture content differences between new and old timber, causing future differential movement and joint failure.
- Inadequate protection of adjacent historic features during works, resulting in accidental damage and costly remedial repairs.
- Underestimating the time required for traditional joinery techniques, leading to rushed work and compromised quality.
- Relying solely on modern materials without considering the historical compatibility or breathability required for traditional timber frames.
- Failing to properly assess the full extent of decay or structural damage before commencing repairs, leading to incomplete restoration.
- Incorrectly identifying timber species, resulting in inappropriate joinery methods or finishing products.
- Not allowing adequate time for timber acclimatisation or for traditional mortars and finishes to cure before loading.
- Misconception: 'All timber is the same, so I can use any type for any job.' Correction: Different timbers have varying strength, durability, and moisture content. For example, softwood like pine is suitable for framing, while hardwood like oak is better for high-end joinery. Always check the specification.
- Misconception: 'I don't need to measure twice if I'm confident.' Correction: Even experienced carpenters make mistakes. Always measure twice and cut once to avoid wasting materials and time. Precision is key to achieving a professional finish.
- Misconception: 'Safety gear is optional if I'm careful.' Correction: Personal protective equipment (PPE) like safety glasses, ear defenders, and dust masks are mandatory on site. Accidents can happen even to the most careful workers, so always wear the correct PPE.
