Setting out to form masonry structures in the workplace
This subtopic focuses on the practical competencies and underpinning knowledge needed to accurately set out masonry structures, including interpreting project documentation, establishing lines and levels, and transferring dimensions from plans to the ground. Mastery of setting out ensures structural integrity, compliance with specifications, and efficient workflow, while preventing costly errors and rework on site.
Assessment criteria
Topic Overview
The Pearson Edexcel Level 2 NVQ Diploma in Trowel Occupations (Construction) is a vocational qualification designed for individuals working in bricklaying or blockwork. It covers essential skills such as interpreting drawings, setting out, mixing mortars, and constructing brick and block walls up to cavity walling and basic arches. This diploma is recognised across the UK construction industry and is a key step towards becoming a qualified bricklayer.
This qualification is part of the Construction & Building Services suite and is typically assessed through on-site observation, written tests, and portfolio evidence. It aligns with the National Occupational Standards (NOS) for trowel occupations, ensuring learners gain practical, job-ready skills. Mastery of this diploma opens pathways to advanced roles like site supervisor or specialist bricklayer, and it is often a prerequisite for higher-level construction qualifications.
Key Concepts
Core ideas you must understand for this topic
- →Setting out: Accurately marking building lines, corners, and levels using profiles, string lines, and spirit levels to ensure walls are square and plumb.
- →Mortar mixing: Understanding correct ratios (e.g., 1:6 cement to sand) and consistency for different applications, including lime mortar for heritage work.
- →Bond patterns: Knowing common bonds like stretcher, English, and Flemish bond, and how to cut bricks (e.g., queen closers) to maintain bond at corners and openings.
- →Cavity wall construction: Building inner and outer leaves with wall ties, insulation, and damp-proof courses (DPC) to prevent moisture ingress.
- →Health and safety: Complying with COSHH regulations for cement dust, manual handling techniques, and using PPE like gloves and goggles.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Credit awarded for demonstrating the correct interpretation of construction drawings, specifications, and setting out data to identify all required dimensions, datums, and grid lines.
- Evidence must show proficient use of setting out tools and instruments, such as profiles, ranging lines, spirit levels, and measuring tapes, to achieve the required accuracy (typically ±3mm for domestic work).
- Assessors should look for consistent checking of squareness (via diagonal measurements) and provision of robust, clearly marked setting out stations that remain visible and protected throughout the build.
Assessment Guidance
Guidance for achieving higher grades
- 💡When compiling a portfolio of evidence, include annotated photographs that show step-by-step progression: initial set-up, key measurements being taken, and final verification of the marked-out positions.
- 💡Explicitly reference current legislation (e.g., CDM 2015) in written accounts or discussions to demonstrate compliance with health and safety duties, and always show correct PPE usage in evidence.
- 💡Prepare to answer professional discussion questions on how you would handle discrepancies between drawings and site conditions—emphasising communication with supervisors and recording any agreed changes.
- 💡Tip 1: In practical assessments, always check your work with a spirit level after every course. Examiners look for consistent plumb and level – a small error early on can compound and lose marks.
- 💡Tip 2: When answering written questions, use technical terms like 'perpend', 'quoin', and 'reveal' correctly. This shows depth of knowledge and can earn you higher marks.
- 💡Tip 3: For portfolio evidence, take clear photos of each stage (e.g., setting out, first course, completed section) and annotate them with what you did and why. This demonstrates understanding, not just doing.
Common Mistakes
Common errors to avoid in your coursework
- Misreading drawing scales or confusing between metres and millimetres, leading to incorrect marking out of positions.
- Neglecting to establish a reliable temporary benchmark or datum, resulting in level errors that compound through the build.
- Failing to protect setting out pins, profiles, or lines from disturbance, which causes loss of accuracy and requires time-consuming re-establishment.
- Misconception: 'Any mortar mix works for all bricks.' Correction: Different bricks (e.g., engineering bricks vs. facing bricks) require specific mortar strengths to avoid cracking or staining. Always check manufacturer guidelines.
- Misconception: 'You don't need to butter the perp ends.' Correction: Full bedding of vertical joints (perps) is essential to prevent water penetration and ensure structural integrity. Leaving gaps weakens the wall.
- Misconception: 'Cavity walls don't need wall ties if the cavity is narrow.' Correction: Building regulations mandate wall ties at specific spacings (e.g., 900mm horizontal, 450mm vertical) regardless of cavity width to tie the two leaves together.
