    OCNLR Level 2 Award in Skills for Professions in Building and Construction

    Topic Overview

    The OCNLR Level 2 Award in Skills for Professions in Building and Construction introduces you to the fundamental skills and knowledge required for a career in the construction industry. This qualification covers key areas such as health and safety, basic construction techniques, and an understanding of building materials and methods. It is designed to provide a solid foundation for further study or entry-level employment in roles like construction operative, labourer, or apprentice.

    You will explore practical skills including measuring, cutting, and joining materials, as well as interpreting simple drawings and specifications. The course also emphasises the importance of working safely on construction sites, covering regulations like the Health and Safety at Work Act 1974 and COSHH. By the end, you'll understand how different trades (e.g., bricklaying, carpentry, plastering) contribute to a construction project.

    This award is part of the wider suite of OCN London qualifications, which are recognised by employers and further education providers. It prepares you for progression to Level 2 or 3 qualifications in specific trades, or for apprenticeships. Mastering these basics is crucial because construction projects rely on teamwork, precision, and adherence to safety standards—skills you'll develop throughout this course.

    Key Concepts

    Core ideas you must understand for this topic

    • →Health and safety legislation: Understand key acts like the Health and Safety at Work Act 1974, COSHH, and RIDDOR, and how they apply to construction sites.
    • →Construction materials and their uses: Know the properties and applications of common materials such as bricks, blocks, timber, concrete, and plasterboard.
    • →Basic construction techniques: Learn how to measure, mark out, cut, and join materials using hand tools and power tools safely.
    • →Interpreting drawings and specifications: Be able to read simple construction drawings, identify symbols, and understand dimensions and scale.
    • →Sustainability in construction: Understand the importance of waste reduction, recycling materials, and using energy-efficient methods.

    Learning Objectives

    What you need to know and understand

    • Identify common hand tools used in roofing and explain their specific functions.
    • Select appropriate materials for fixing plain roof tiles, considering weight, profile, and durability.
    • Explain relevant health and safety legislation and its application to roofing tasks.
    • Demonstrate safe manual handling techniques when lifting and transporting roofing materials.
    • Set up a safe working area at height, including ladder and scaffold safety measures.
    • Fix plain roof tiles correctly to a battened sloping surface following manufacturer's guidelines.
    • Inspect completed tiling for alignment, coverage, and weathering integrity to ensure compliance with standards.

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for correctly identifying and laying out required hand tools (e.g., trowel, hammer, gauge rod).
    • Expect learners to accurately calculate tile quantities and batten spacing from given roof dimensions.
    • Credit for consistently wearing appropriate PPE (hard hat, safety boots, fall arrest harness) and setting up safe access equipment.
    • Assess ability to fix plain tiles neatly, maintaining correct head lap (65mm minimum) and side lap.
    • Look for evidence of secure fixing: nails fully driven without splitting tiles, and use of clips where specified.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Always perform and document a point-of-work risk assessment before starting; examiners value this as evidence of health and safety understanding.
    • 💡Practice the sequence of setting out and fixing tiles on a small test rig to refine technique and speed.
    • 💡Use correct terminology (head, tail, nib, batten, lap) when discussing your work to show technical knowledge.
    • 💡Check your finished work against the specification and use a gauge stick to verify consistent batten spacing.
    • 💡Always use correct terminology in your answers. For example, refer to 'personal protective equipment (PPE)' rather than just 'safety gear'. Examiners look for precise language that shows you understand the concepts.
    • 💡When answering questions about health and safety, always link your points to specific legislation or regulations. For instance, mention the Health and Safety at Work Act 1974 when discussing employer/employee responsibilities.
    • 💡Practice interpreting drawings by measuring real objects and comparing them to scaled drawings. This will help you understand scale and dimensions, which are common exam topics.

    Common Mistakes

    Common errors to avoid in your coursework

    • Neglecting to secure ladders properly or overreaching during tile fixing, leading to fall risks.
    • Using incorrect nail types (e.g., too large or too long) causing tile fractures or inadequate grip.
    • Misalignment of tiles resulting in uneven courses and poor weathering performance.
    • Failing to adjust for roof pitch when setting out batten gauges, causing incorrect lap.
    • Omitting underlay or ventilation details, leading to moisture ingress and condensation.
    • Misconception: 'Health and safety is just common sense, so I don't need to study it.' Correction: Health and safety in construction is governed by specific laws and regulations. You must know the legal requirements, not just rely on intuition, to prevent accidents and avoid legal penalties.
    • Misconception: 'All bricks are the same.' Correction: Bricks vary in material (clay, concrete), strength, and purpose (e.g., facing bricks vs. engineering bricks). Using the wrong type can compromise structural integrity.
    • Misconception: 'Power tools are always faster and better than hand tools.' Correction: Hand tools are often more precise for certain tasks (e.g., marking out) and safer in confined spaces. Knowing when to use each is essential.
