Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating accurate interpretation of working drawings, including identifying dimensions, symbols, scales, and reference points to establish the correct position of walls and openings.
- Credit should be given for correctly selecting and using tools and equipment (e.g., tape measures, spirit levels, builder's squares, line and pins) and for wearing appropriate PPE (safety boots, gloves, hard hat, hi-vis vest) throughout the setting out process.
- Assessors must see evidence that the work area is cleared, cleaned, and made safe before setting out begins, including checking for underground services and establishing stable benchmarks.
- Marks allocated for carrying out setting out procedures systematically: establishing a primary baseline, setting out right angles using the 3-4-5 method or a builder’s square, checking diagonals for square, and transferring levels accurately.
- Award credit for completing the works by checking all measurements against the specification, correcting any errors, and leaving the area tidy, with profiles and lines securely fixed and clearly marked for follow-on trades.
- Award credit for correctly interpreting setting out information from drawings, including identifying dimensions, datum points, and grid lines, and translating them to the site.
- Award credit for selecting appropriate tools (e.g., tape measure, builder’s level, corner profiles) and PPE (e.g., safety boots, hard hat, hi-vis), and justifying their use.
- Award credit for preparing the work area by clearing debris, establishing a level base, and ensuring safe access, with risk assessment considerations.
- Award credit for accurately establishing building lines, corners using the 3-4-5 method, and transferring levels using a water or laser level, with recorded measurements.
- Award credit for completing the setting out by checking squareness, dimensions, and level, and documenting any adjustments made, in line with quality control procedures.
Assessment Guidance
Guidance for achieving higher grades
- 💡In practical assessments, always start by establishing a robust datum point or temporary benchmark and work methodically from that reference to avoid cumulative errors across the site.
- 💡Double-check all right angles using the 3-4-5 triangulation method or an optical square; this verification can be done quickly and demonstrates a professional approach.
- 💡During coursework, document each step with photographs and notes showing you checking measurements, using equipment correctly, and wearing PPE—this supports your evidence of competence.
- 💡If using profiles, ensure they are set well clear of proposed excavations and marked with cut or fill levels; label everything clearly to avoid confusion during assessment.
- 💡Provide a detailed method statement in your portfolio, explaining each stage of setting out with clear, annotated photographs showing key steps like datum establishment and corner profiling.
- 💡Demonstrate your understanding of tolerances by including how you checked and recorded allowed deviations, and what corrective actions you would take if out of tolerance.
- 💡Always reference the relevant British Standard or building regulation in your evidence to show professional awareness, especially BS 8000 for workmanship.
- 💡Practice recording measurements in a consistent format, and cross-referencing them with the drawing to showcase accuracy and thoroughness to the assessor.
- 💡Always use correct technical terminology in answers; for example, 'perpend' not 'vertical joint' in formal questions.
- 💡Show all calculations step-by-step, including units, to gain method marks even if the final answer is incorrect.
- 💡In practical assessments, demonstrate safe working practices consistently; examiners look for this throughout, not just at the start.
Common Mistakes
Common errors to avoid in your coursework
- Students often misread scales on drawings, leading to incorrect full-size measurements (e.g., confusing 1:50 with 1:100), which can cause the entire layout to be out of tolerance.
- A frequent error is neglecting to check diagonals for square after setting out corners; a difference of a few millimetres can result in a rhomboid-shaped structure and subsequent brickwork not meeting specifications.
- Learners may fail to allow for the width of the brickwork (e.g., ignoring wall thickness) when marking foundation lines, so the centre line of the wall is not correctly positioned.
- Forgetting to secure profiles and lines properly can cause movement during use, leading to progressive inaccuracies; lines left loose or sagging are a common issue.
- Many students rely solely on visual alignment rather than using a spirit level to check horizontals and verticals, resulting in out-of-plumb corners and uneven brick courses.
- Misinterpreting scale or dimensions from the drawing, leading to incorrect set-out lines.
- Neglecting to account for the thickness of mortar joints when transferring dimensions from the plan, causing cumulative errors.
- Failing to check and calibrate measuring tools, such as a tape measure with a worn hook or an uncalibrated level.
- Poorly securing setting out pegs or profiles, which can shift during construction, leading to misalignment.
- Not verifying squareness of corners properly, often relying solely on a builder’s square instead of diagonal measurement or the 3-4-5 method.
- Misconception: All bricks are the same size. Correction: Standard UK brick size is 215mm × 102.5mm × 65mm, but specials and non-standard sizes exist.
- Misconception: Mortar mix is always the same. Correction: Mix ratios vary (e.g., 1:6 for general use, 1:3 for below ground) depending on strength and exposure.
- Misconception: A level is only needed for the first course. Correction: Walls must be checked for level, plumb, and straightness at every course to avoid cumulative errors.

Question: Calculate the number of bricks required to build a single-leaf wall that is 6 metres long and 1.5 metres high. Assume 60 bricks per square metre and add 5% for waste.
- 1.Step 1: Calculate the area of the wall: Area = length × height = 6m × 1.5m = 9m².
- 2.Step 2: Multiply area by bricks per square metre: 9 × 60 = 540 bricks.
- 3.Step 3: Add 5% waste: 540 × 1.05 = 567 bricks. Round up to 567 (since you can't order part bricks).
Question: Describe the correct procedure for laying a brick to ensure a proper perpend joint. (6 marks)
- 1.Step 1: Apply a bed of mortar to the course, furrowing it to ensure an even bed.
- 2.Step 2: Butter the end of the brick with mortar to form the perpend joint.
- 3.Step 3: Place the brick against the previous one, pressing down and pushing towards the perpend to ensure a full vertical joint.
- 4.Step 4: Check level and alignment using a spirit level and string line.
- 5.Step 5: Remove excess mortar and finish the joint with a jointer.
