    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Annotate before-and-after photographs to explain defect identification, material choices, and techniques used.
    • 💡Practice articulating the rationale behind your repair decisions to demonstrate underpinning knowledge during assessor questions.
    • 💡Ensure all work is signed off by your supervisor against the contract specification and include this in your portfolio.
    • 💡Use a daily diary to capture challenges faced and solutions applied, showing reflective practice and time management.
    • 💡Ensure your portfolio includes dated, annotated before-and-after photographs for each repair type, clearly linked to the relevant learning outcome.
    • 💡Gather a variety of witness testimonies from different sources (supervisors, contractors, clients) to evidence compliance with site-specific standards and communication.
    • 💡Keep a detailed daily log of resources used, tool calibration checks, and any deviations from original specifications, with explanations, to demonstrate reflective practice.

    Common Mistakes

    Common errors to avoid in your coursework

    • Neglecting to protect adjacent surfaces, causing irreversible staining from mortar smears or dust.
    • Using a mortar mix stronger than the original, leading to differential movement and future cracking.
    • Failing to cut out defective bricks to the required depth, resulting in poor keying and weak bonding.
    • Misinterpreting specifications and ordering wrong replacement bricks that differ in size or colour.
    • Failing to identify underlying structural issues (e.g., subsidence) before cosmetic repointing, leading to recurrence of defects.
    • Using cement-based mortar on historic lime mortar walls, causing moisture entrapment and accelerated decay.
    • Neglecting to protect adjacent surfaces, resulting in staining or physical damage from tools and debris.
    • Misinterpreting contract tolerances on alignment or finish, leading to rework and time overruns.
    • Failing to rake out joints to the correct depth before repointing, leading to poor adhesion
    • Using the wrong mortar strength or mix ratio for the type of masonry, causing future deterioration
    • Neglecting to protect adjacent surfaces from mortar splashes and staining
    • Overlooking the need for temporary support when removing structural brickwork
    • Inaccurate measurement or cutting of replacement bricks, resulting in uneven joints or misalignment
    • Misconception: 'Any mortar mix will do as long as it sticks.' Correction: Mortar mix must be specified for the brick type and location (e.g., lime mortar for soft bricks). Using the wrong mix can cause cracking or failure.
    • Misconception: 'Bricks don't need to be wetted before laying.' Correction: Dry bricks absorb water from mortar too quickly, weakening the bond. In hot weather, wetting bricks is essential to ensure proper curing.
    • Misconception: 'Cavity walls don't need wall ties if the gap is small.' Correction: Wall ties are mandatory to connect the two leaves and prevent collapse. They must be installed at specified intervals and with correct laps.
