    Common Exam Mistakes

    Pitfalls to avoid in your exams

    • •Relying solely on utility plans without physical detection, not realising that plans may be out of date or inaccurate.
    • •Forgetting to check for the presence of electricity cables in 'power' mode before using 'radio' or 'genny' modes, leading to missed live services.
    • •Marking the ground with incorrect colour codes, causing confusion and potential strikes by excavators.
    • •Assuming the depth of cover is uniform; services may have been laid at varying depths due to ground conditions or later modifications.
    • •Using technical jargon when speaking to members of the public, leading to confusion or misunderstandings.
    • •Failing to document advice given or information shared, particularly when it relates to safety instructions or changes to planned works.
    • •Not verifying that the receiver has understood the information, especially when giving verbal instructions on-site.
    • •Overlooking the need to inform all affected parties, such as residents, businesses, and local authorities, about imminent disruptions.

    Top Examiner Tips

    Expert advice for exam success

    • •Always adopt the 'locate, mark, confirm' sequence: use plans and equipment to detect, clearly mark the route, then verify with trial holes if needed—document each step.
    • •Discuss the limitations of detection equipment during your assessment; mention that some pipes (e.g., plastic water mains without tracer wire) may not be detected and require alternative methods like ground-penetrating radar or reference to installation depth records.
    • •When observed, communicate clearly with your team about the location of marked services and the safety exclusion zones, demonstrating effective pre-excavation briefings as per HSG47 guidance.
    • •When preparing evidence for this unit, include records of briefings, copies of written notices, and reflective accounts that demonstrate how you adapted your communication for different situations.
    • •In role-play assessments, actively show checking for understanding by asking open-ended questions and summarising key points.
    • •Be prepared to explain how you would handle a scenario where the information you need to convey is complex or technical, such as explaining pipe-laying methods to a householder.
    • •When answering questions on legislation, always reference specific regulations (e.g., HSG47, Electricity at Work Regulations) and explain their practical implications for utility avoidance.
    • •In practical assessments, systematically perform a site scan with a CAT before and after connecting a signal generator, demonstrating a methodical approach to service detection.
