    Learning Objectives

    What you need to know and understand

    • Describe the characteristics and types of stone suitable for dry stone walling
    • Outline the sequence of operations required to construct a dry stone wall
    • Demonstrate correct setting-out and excavation of foundations to specified dimensions
    • Apply appropriate stone-laying techniques to build a structurally sound wall
    • Identify potential hazards and implement control measures throughout the task
    • Carry out post-construction site clearance, including segregation and disposal of waste
    • Evaluate own performance against given quality and safety standards
    • 1. Know about the preparation and construction of a dry stone wall.2. Be able to prepare the foundations.3. Be able to construct a dry stone wall.4. Be able to leave the site clear, tidy, and safe.5. Know how to work safely.

    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Accurate measurement and marking out of the wall line on the ground
    • Foundation trench dug to correct depth, width, and level, with base compacted
    • Correct use of PPE (safety boots, gloves, hard hat where required) throughout
    • Evidence of throughstones or tie-stones placed at regular intervals for stability
    • Wall built with consistent batter and no vertical joints exceeding 20 cm
    • Finished wall meets specified length, height, and width tolerances
    • All tools and surplus materials removed; site left free of debris and trip hazards
    • Award credit for correctly identifying and preparing a stable trench foundation to at least 150mm depth and proper width.
    • Award credit for selecting and placing stones to create a battered profile with through-stones at regular intervals.
    • Award credit for demonstrating safe manual handling (e.g., correct lifting, use of gloves and steel-toe boots) throughout the task.
    • Award credit for completing the wall with firm copestones and leaving the site free from debris, with tools cleaned and stored.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Plan the wall layout and gather all tools and materials before you begin
    • 💡Photograph key stages (foundation, first course, throughstones, finished wall) for portfolio evidence
    • 💡Practice sorting your stone pile into sizes and shapes to work efficiently
    • 💡Constantly check batter and level – adjustments are much harder after several courses
    • 💡Safety is assessed as strictly as the wall quality; always wear PPE and demonstrate safe lifting
    • 💡Always begin by inspecting your worksite and personal protective equipment, and verbally confirm safety checks to the assessor.
    • 💡Demonstrate good practice by periodically stepping back to assess the wall’s line and batter—this shows attention to quality.
    • 💡When finishing, show awareness of site safety by checking for stray tools or leftover stone chips before calling the job complete.
    • 💡Use specific examples from your own experience to demonstrate your understanding of employability skills. For instance, describe a time you worked in a team to complete a project.
    • 💡Read each question carefully and ensure you address all parts. Many students lose marks by missing key words like 'explain' or 'evaluate'.
    • 💡Practice applying skills in different contexts. The exam may ask you to adapt your communication style for a formal report versus a casual team meeting.

    Common Mistakes

    Common errors to avoid in your coursework

    • Failing to compact the foundation base, leading to later settlement
    • Using rounded or irregular stones that do not interlock securely
    • Creating continuous vertical joints (traps) that weaken the wall structure
    • Neglecting to step back the wall face (batter) for stability
    • Overlooking the need for regular checks with a spirit level and line
    • Not sorting stones before starting, wasting time during construction
    • Leaving sharp or protruding stones that pose a safety risk after completion
    • Failing to set up a string line or batter frame to maintain consistent wall alignment and batter.
    • Using only small stones in the core without enough larger tie-stones to lock the faces together.
    • Not checking for and removing unstable stones or hazards from the work area before starting.
    • Leaving gaps and voids in the wall hearting that weaken the structure.
    • Misconception: Communication is just about talking clearly. Correction: Effective communication also involves active listening, reading body language, and choosing the right medium (e.g., email vs. face-to-face).
    • Misconception: Teamwork means everyone does the same amount of work. Correction: Good teamwork involves playing to individual strengths and supporting others when needed, not necessarily equal division of tasks.
    • Misconception: Problem-solving is only for managers. Correction: Every employee faces problems, and being able to solve them independently shows initiative and reliability.
