Assessment Criteria
Key criteria assessors look for in your portfolio
- Credit evidence of accurate interpretation of drawings, specifications, and method statements
- Look for demonstration of knowledge regarding COSHH, RIDDOR, and building regulations
- Observe correct use of PPE and safe handling of tools and materials
- Check that selected bricks/stones match existing in color, texture, and size; and mortar composition is appropriate
- Verify that protective measures (e.g., sheeting, barriers) are in place before work starts
- Assess timekeeping and planning through logbooks or witness testimony
- Inspect finished work against contract requirements, including appearance and structural integrity
Assessment Guidance
Guidance for achieving higher grades
- 💡During professional discussion, reference specific legislation (e.g., Health and Safety at Work Act) and how it applies to your role
- 💡Compile a detailed portfolio with photographic evidence of material matching and protection measures
- 💡Show an understanding of the conservation philosophy by explaining the rationale behind your choice of repair technique
- 💡Practice estimating and tracking time for each stage to demonstrate effective time management
- 💡Use clear annotations on drawings or work records to show your interpretation of the project information
- 💡Always use technical terminology correctly, such as 'perpend', 'course', 'quoin', and 'gauge'. This demonstrates your knowledge and impresses the examiner.
- 💡In practical assessments, always talk through what you are doing. This shows the assessor that you understand the process, not just that you can do it mechanically.
- 💡For written exams, read the question carefully and identify the command word (e.g., 'describe', 'explain', 'calculate'). Tailor your answer to the command word to ensure you meet the mark scheme.
Common Mistakes
Common errors to avoid in your coursework
- Using off-the-shelf materials without matching historical fabric, causing visual and material incompatibility
- Neglecting to conduct a risk assessment for the specific conservation task
- Applying modern construction techniques that may damage historic structures
- Misreading conservation plans, leading to incorrect repair methods
- Failing to protect adjacent surfaces from mortar splashes or tool damage
- Misconception: The 3-4-5 method is always the best for setting out. Correction: It is only suitable for small areas; for large buildings, the equal diagonal method is more accurate and should be used.
- Misconception: More water makes mortar easier to work with and is harmless. Correction: Excess water weakens the mortar and causes shrinkage cracks; the correct consistency is crucial for strength.
- Misconception: Any brick can be used for any part of a wall. Correction: Different bricks have different strengths and frost resistance; you must select the correct brick for the location, e.g., engineering bricks for damp areas.
Revision Plan
How to revise this topic in 1–2 weeks
- 1Week 1: Focus on health and safety regulations and setting out techniques. Revise the 3-4-5 method and practice calculations. Create flashcards for key terms and PPE requirements.
- 2Week 2: Study mortar mixes and brick construction methods. Practice mixing mortar to the correct consistency and laying bricks to line and level. Review common bonds and their applications.
- 3Week 3: Consolidate your knowledge by attempting past exam questions and practical scenarios. Identify weak areas and revisit them. Use active recall to test yourself on key facts.
- 4Week 4: Simulate the assessment environment: time yourself on written questions and perform a practical task while explaining your actions. Review feedback from your tutor or assessor.
Exam Question Types
How this topic typically appears in the exam
- 📋Multiple-choice questions on health and safety regulations, PPE, and tools. Tip: Read each option carefully; often two are similar, so eliminate the obviously wrong ones first.
- 📋Short-answer questions requiring you to define terms or list items, such as 'List four types of PPE used when cutting bricks'. Tip: Be precise and use the correct terminology.
- 📋Calculation questions for brick quantities or setting out. Tip: Show all working out, including units, to gain method marks even if the final answer is wrong.
- 📋Extended response questions (6 marks) asking you to describe a procedure, such as 'Describe how to set out a right angle using the 3-4-5 method'. Tip: Use a step-by-step approach and include a diagram if possible.
Command Word Expectations (PEARSON)
What examiners look for when using specific command words in this specification
Provide a detailed account of a process or procedure, including the steps involved and the reasons for each step. For example, 'Describe how to mix mortar by hand' requires you to mention the ratio, the mixing process, and the consistency check.
Give reasons or causes for a phenomenon. For example, 'Explain why a damp proof course is necessary' requires you to discuss rising damp, its effects, and how the DPC prevents it.
Perform mathematical operations to find a numerical answer. Show all working and include units. For example, 'Calculate the number of bricks needed for a wall' requires you to show the formula and substitution.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A wall is to be built using standard bricks (215mm x 102.5mm x 65mm) with a 10mm mortar joint. Calculate the number of bricks required for a single-leaf wall that is 5 metres long and 2 metres high. (Assume no wastage and ignore openings).
- 1.Step 1: Convert all measurements to millimetres: wall length = 5000mm, wall height = 2000mm.
- 2.Step 2: Calculate the number of bricks along the length: (5000 / (215 + 10)) = 5000 / 225 = 22.22, so 23 bricks (round up).
- 3.Step 3: Calculate the number of courses (rows) high: (2000 / (65 + 10)) = 2000 / 75 = 26.67, so 27 courses.
- 4.Step 4: Multiply the number of bricks per course by the number of courses: 23 x 27 = 621 bricks.
Question: Describe the correct procedure for mixing mortar by hand for bricklaying, including the correct ratio for a general-purpose mix (1:1:6) and the importance of consistency.
- 1.Step 1: State the ratio: 1 part cement, 1 part lime, 6 parts sand by volume.
- 2.Step 2: Describe the process: Measure the materials accurately using a gauge box or shovel, mix the dry materials thoroughly until a uniform colour is achieved, then gradually add clean water while mixing until the mortar reaches a workable consistency that holds its shape when squeezed.
- 3.Step 3: Explain the importance: The correct ratio ensures strength and workability; too much water weakens the mortar, too little makes it hard to work with. Consistency should be similar to wet sand.
- 4.Step 4: Mention that mortar should be used within 2 hours and re-tempered if necessary, but not after it has begun to set.
