    Open Awards Level 1 Diploma in Exploring Construction and Building Crafts (RQF)
    Open Awards Level 1 Certificate in Exploring Construction and Building Crafts (RQF)

    Topic Overview

    The Open Awards Level 1 Diploma in Exploring Construction and Building Crafts (RQF) is an introductory qualification designed for students who are new to the construction industry. It covers the fundamental skills and knowledge required across multiple trades, including bricklaying, carpentry, painting and decorating, and plumbing. This diploma provides a broad foundation, helping learners understand the key principles of health and safety, tools and materials, and basic construction techniques. It is ideal for those considering a career in construction or progressing to a Level 2 qualification.

    This qualification matters because it equips students with practical, hands-on experience and theoretical understanding that are essential for safe and effective work on construction sites. It also develops employability skills such as teamwork, communication, and problem-solving. By exploring different crafts, students can make informed decisions about which trade to specialise in, reducing the risk of choosing a career path that doesn't suit them. The diploma is recognised by employers and further education providers, making it a valuable stepping stone into the construction sector.

    Within the wider subject of Construction and Building Services, this diploma sits at the entry level, providing a comprehensive introduction. It aligns with industry standards and prepares students for more advanced study, such as Level 2 Diplomas in specific trades. The curriculum is designed to reflect real-world practices, ensuring that learners gain relevant skills that can be applied immediately in a supervised work environment. By covering multiple crafts, it also highlights how different trades interact on a construction project, fostering a holistic understanding of the building process.

    Key Concepts

    Core ideas you must understand for this topic

    • →Health and safety regulations: Understanding the Health and Safety at Work Act 1974, risk assessments, and the use of personal protective equipment (PPE) to prevent accidents on site.
    • →Tools and materials: Identifying and using hand tools, power tools, and construction materials correctly, including their storage and maintenance.
    • →Basic construction techniques: Learning fundamental skills such as measuring, cutting, joining, and assembling materials in trades like bricklaying, carpentry, and plumbing.
    • →Communication and teamwork: Working effectively with others, following instructions, and reporting issues to supervisors to ensure project efficiency and safety.
    • →Sustainability and waste management: Understanding the importance of reducing waste, recycling materials, and using resources responsibly in construction projects.

    Learning Objectives

    What you need to know and understand

    • Be able to prepare to apply plaster materials to internal backgrounds., Be able to apply materials to internal backgrounds., Be able to apply plaster to internal brick or block backgrounds.
    • Be able to prepare to apply plaster materials to internal backgrounds., Be able to apply materials to internal backgrounds., Be able to apply plaster to internal brick or block backgrounds.

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for demonstrating thorough preparation of the brick/block background, including removing debris, dampening if required, and applying a suitable bonding agent where specified.
    • Award credit for mixing plaster material to a consistent, workable paste free from lumps, using the correct water-to-plaster ratio and clean mixing equipment.
    • Award credit for applying plaster using a hawk and trowel in even, consistent coats of appropriate thickness (typically 2–3mm for finishing plaster) without excessive slumping.
    • Award credit for achieving a flat and level surface finish, free from trowel marks, ridges, or hollows, and for correctly keying any base coat for subsequent applications.
    • Award credit for correctly identifying and preparing the background, including removing dust, debris, and applying a bonding agent or dampening if required.
    • Award credit for mixing plaster to a uniform, lump-free consistency appropriate for the application stage (e.g., browning, bonding, or finishing plaster).
    • Award credit for demonstrating correct trowel technique, including laying on an even base coat and ensuring adhesion to the background.
    • Award credit for achieving a flat surface without hollows or ridges, using a straight edge to check for deviations.
    • Award credit for cleaning tools and work area after completion, following health and safety regulations.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Practice timing: mix only as much plaster as you can apply within its working time (typically 20–30 minutes) to avoid wasting material and rushing the finish.
    • 💡Use a straightedge or spirit level frequently during application to check for hollows or high spots, and remove excess plaster before it sets to minimize sanding.
    • 💡When preparing brick/block backgrounds, always assess suction levels—overly porous surfaces may require dampening or priming to prevent rapid water loss from the plaster.
    • 💡Practice mixing plaster to the correct consistency using the water-to-plaster ratio recommended by the manufacturer; consistency is key to a smooth finish.
    • 💡Always check your background surface is stable, clean, and free from dust before starting your practical assessment.
    • 💡During the assessment, work systematically: start from the top corner and work downwards and across, maintaining a consistent thickness.
    • 💡Observe time limits for each coat; overworking plaster can cause it to lose workability, so plan your application sequence.
    • 💡Tip 1: Focus on health and safety – it's a core theme across all units. Know key legislation, risk assessment steps, and PPE types. Marks are often awarded for demonstrating safe practices in practical assessments.
    • 💡Tip 2: Practice using tools correctly and safely. In practical exams, examiners look for proper technique, not just speed. Show that you can handle tools with care and precision.
    • 💡Tip 3: Read questions carefully. Many students lose marks by misinterpreting what is asked. Underline key words like 'describe', 'explain', or 'list' to ensure you answer appropriately.

    Common Mistakes

    Common errors to avoid in your coursework

    • Neglecting to remove dust, loose particles, or salts from the background, leading to poor adhesion and potential failure of the plaster application.
    • Mixing plaster too wet or too dry, which either causes rapid slumping and low strength or premature setting and difficulty in spreading evenly.
    • Applying plaster coats that are too thick in a single pass, resulting in cracking, sagging, or extended drying times that compromise the final flatness.
    • Failing to key the base coat adequately before applying a finishing coat, causing delamination between layers and an unsightly, weak surface.
    • Failing to properly dampen the background before applying plaster, leading to poor adhesion and cracking.
    • Mixing plaster too wet or too dry, causing slumping or difficulty in application.
    • Applying plaster too thickly in one coat, resulting in slumping or delayed drying.
    • Not cleaning tools immediately after use, leading to hardened plaster that damages equipment.
    • Misconception: Construction work is purely physical and doesn't require much thinking. Correction: Construction involves problem-solving, planning, and technical knowledge, such as calculating material quantities or interpreting drawings.
    • Misconception: Safety rules are optional if you're quick. Correction: Safety procedures are legal requirements; ignoring them can lead to serious injuries, fines, or job loss. Always follow protocols.
    • Misconception: All trades are the same, so you can switch easily. Correction: Each trade requires specific skills and knowledge. While some basics overlap, specialisation is needed for proficiency.
