Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating a systematic review of project data, including drawings, specifications, and schedules, to identify constraints and opportunities.
- Evidence of consulting with relevant parties (e.g., designers, clients, suppliers) when initial data is insufficient, showing clear documentation of additional information obtained.
- Selection of work methods that explicitly align with resource efficiency (labour, materials, equipment), statutory regulations (e.g., CDM 2015, Building Regulations), and contractual terms.
- Clear communication records (e.g., site instructions, method statements, toolbox talks) confirming the selected work method to operatives and stakeholders.
- Award credit for accurately interpreting project data (drawings, specifications, work schedules) to identify the specific heritage plastering requirements, including material matches and application techniques.
- Evidence must show the candidate actively sought additional information from appropriate sources (e.g., architect, conservation officer, original lime mortar analysis) when initial project data was incomplete or ambiguous.
- The candidate's method statement or discussion should demonstrate how the chosen plastering approach optimises the use of materials, tools, and labour while respecting statutory heritage constraints (e.g., listed building consent) and contract terms.
- Award credit for demonstrating how project specifications, drawings, and schedules were cross-referenced to decide the cladding installation method.
- Evidence must show that when data was insufficient, alternative sources (e.g. manufacturer technical helplines, structural engineer) were consulted and documented.
- Assess whether the chosen methods explicitly consider resource efficiency (labour, materials, time) and compliance with health, safety, and environmental regulations.
- Observation records or witness testimonies must confirm that the selected work method was clearly communicated to site management, operatives, and any affected parties.
Assessment Guidance
Guidance for achieving higher grades
- 💡When compiling your portfolio, include annotated copies of project documents showing how you extracted key information to inform the method.
- 💡Provide evidence of decision-making processes, such as comparison tables or meeting notes, to justify the chosen work method.
- 💡Ensure method statements are signed and dated, demonstrating that they were communicated and acknowledged by the team.
- 💡Reference relevant standards and regulations (e.g., BS 5534 for slating and tiling) to show compliance.
- 💡When submitting evidence, include a decision log that cross-references each element of the project data with the selected method, explicitly noting how it meets heritage conservation principles.
- 💡In workplace observations, demonstrate a systematic approach: check specifications, identify gaps, consult appropriate sources, then outline your method to the assessor or supervisor before commencing work.
- 💡Prepare concise written method statements for your portfolio that clearly justify choices in terms of resource efficiency, health and safety, and compliance with the Building Regulations and Planning (Listed Buildings and Conservation Areas) Act 1990.
- 💡Link your decisions directly to the specific project data you assessed; use reference numbers from drawings or specifications in your portfolio evidence.
- 💡Include a log of any additional information requests (emails, phone calls, meeting notes) to demonstrate proactive sourcing of missing data.
- 💡Present a risk assessment and method statement that are tailored to the chosen cladding technique and site conditions.
- 💡Obtain signed witness testimonies from those who received the method briefing to validate effective communication and confirmation.
- 💡Tip 1: When answering questions about roof geometry, always show your working out for calculations (e.g., roof area, tile quantities). Examiners award marks for method, even if the final answer is slightly off.
- 💡Tip 2: In practical assessments, focus on health and safety throughout. Start by checking your PPE and equipment, and mention safety points during your commentary. This demonstrates a professional attitude and can earn you extra marks.
- 💡Tip 3: Use technical terminology correctly. For example, distinguish between 'battens' (horizontal supports for tiles) and 'counter-battens' (vertical supports for ventilation). Misusing terms can lose marks and suggest a lack of understanding.
Common Mistakes
Common errors to avoid in your coursework
- Failing to consider all relevant project data, such as missing structural reports or weather constraints, leading to inappropriate method selection.
- Assuming that standard methods always suffice without assessing site-specific risks or resource limitations.
- Communicating the method verbally without formal documentation, resulting in inconsistencies and disputes.
- Overlooking statutory requirements like Working at Height Regulations, leading to non-compliant work plans.
- Assuming modern gypsum-based plasters can be directly substituted for traditional lime-based systems without considering breathability and structural movement requirements of historic fabric.
- Proceeding with work based on incomplete or assumed data rather than obtaining missing details, leading to non-compliant repairs that may damage the heritage asset.
- Failing to communicate the selected work method clearly to other trades or supervisors, resulting in inconsistencies in the plastering application and potential conservation failures.
- Relying on unverified or outdated project data without cross-checking current revisions.
- Overlooking the need to source missing information, leading to assumptions that create non-compliance or rework.
- Selecting work methods based on tradition or personal preference rather than analysing resource constraints and contractual requirements.
- Failing to document the confirmed method or obtain formal sign-off, resulting in miscommunication and disputes.
- Misconception: All roofing felt is the same. Correction: Roofing underlays vary by type (e.g., breathable vs. non-breathable) and must be chosen based on roof pitch, ventilation requirements, and tile type. Using the wrong underlay can lead to condensation and rot.
- Misconception: You can install any tile on any roof pitch. Correction: Tiles have minimum pitch requirements to prevent water ingress. For example, plain tiles need a minimum pitch of 35°, while interlocking tiles can be used on pitches as low as 17.5°. Ignoring this can cause leaks.
- Misconception: Lead flashings are always the best choice. Correction: While lead is durable, it can be expensive and requires skilled welding. Modern alternatives like aluminium or flexible flashings may be more cost-effective and easier to install, especially on complex roof details.
