Segregating the Area for Highways Works in the Workplace
This element covers the essential practices for establishing and maintaining safe segregation of highways worksites. Learners will understand how to interpret project information, select appropriate resources, and implement measures to protect workers, public, and property while complying with legislation and contract specifications. Effective segregation ensures work proceeds without incident and meets quality standards.
Assessment criteria
Topic Overview
The GQA Level 2 Diploma in Construction and Cabling Operations when Building an External Fibre Network covers the essential skills and knowledge required to install, terminate, and test fibre optic cables in external environments. This qualification is part of the Construction & Building Services sector and is regulated by GQA Qualifications Limited. It focuses on practical operations such as trenching, ducting, blowing fibre, splicing, and final testing, ensuring students can work safely and effectively on external fibre networks, which are critical for modern telecommunications infrastructure.
This diploma is vital because external fibre networks form the backbone of high-speed internet, connecting homes, businesses, and mobile towers. Students learn to interpret network designs, select appropriate materials, and use specialist tools like fusion splicers and OTDRs. The qualification also emphasises health and safety regulations, including CDM 2015 and NRSWA (New Roads and Street Works Act), preparing learners for real-world construction environments. Mastery of these skills opens career paths as a cable installer, fibre engineer, or network technician.
Within the wider subject of construction and building services, this diploma sits alongside other utilities installation qualifications. It bridges the gap between civil engineering (digging trenches and reinstating surfaces) and telecommunications (fibre splicing and testing). Students must understand how their work integrates with other trades, such as groundworkers and electricians, to deliver a complete network. The qualification is hands-on, with assessments covering both practical tasks and underpinning knowledge.
Key Concepts
Core ideas you must understand for this topic
- →Fibre optic cable types: Understand the differences between single-mode (OS1/OS2) and multi-mode (OM1-OM5) fibres, including their core sizes, bandwidth, and typical applications in external networks.
- →Splicing techniques: Master both fusion splicing (using an arc fusion splicer) and mechanical splicing, knowing when to use each method and how to achieve low-loss joints (<0.1 dB for fusion).
- →Cable blowing and installation: Learn the process of blowing fibre cables into pre-installed ducts using compressed air or water, including calculating blowing distances and avoiding cable damage.
- →Testing and fault finding: Use an Optical Time Domain Reflectometer (OTDR) and power meter to measure loss, locate breaks, and verify splice quality. Understand how to interpret OTDR traces.
- →Health and safety compliance: Apply CDM regulations, risk assessments, and safe digging practices (e.g., CAT and Genny use for utility avoidance). Know NRSWA requirements for street works.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating accurate interpretation of given work instructions and contract specifications related to segregation.
- Award credit for selecting the correct type and quantity of resources (signs, cones, barriers) as per the method statement and site conditions.
- Award credit for consistently maintaining a safe working area, with clear evidence of compliance with legislation and official guidance throughout the activity.
- Award credit for demonstrating accurate interpretation of the provided traffic management layout, risk assessments, and method statements to set up the segregation exactly as specified.
- Expect photographic or video evidence showing correct placement of all required resources (e.g., advance warning signs at prescribed distances, cones with the correct spacings, high-visibility barriers) in line with national guidance.
- Look for recorded decisions on adapting segregation to site-specific conditions while remaining compliant, such as adjusting barrier positions due to unexpected obstacles or traffic flow changes, with rationale explained.
- Interpret given information to plan segregation.
- Comply with relevant legislation and guidance.
- Maintain safe working practices throughout.
- Select and use resources correctly.
- Minimise damage to work and surrounding area.
- Complete work within allocated time and to specification.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always cross-reference your work with the site-specific traffic management plan and risk assessments to ensure compliance before starting.
- 💡Provide comprehensive photographic evidence and witness testimonies that clearly show your involvement in all stages of segregation setup and maintenance.
- 💡Demonstrate your competence across a range of scenarios, including night works, varying traffic conditions, and different types of highways, to strengthen your portfolio.
- 💡Ensure your portfolio includes a detailed witness testimony from a supervisor or qualified assessor that specifically validates your competence in setting up and removing segregation safely, alongside dated photographs or time-lapse videos.
- 💡Explicitly reference the relevant sections of the Traffic Signs Manual (e.g., Chapter 8 Part 1 for static sites) and your compliance with site-specific contract requirements in your reflective account to demonstrate underpinning knowledge.
- 💡Document how you managed time constraints by comparing planned versus actual durations and note any corrective actions taken to complete segregation within the job’s allocated period, as this shows awareness of productivity.
- 💡Always conduct a risk assessment before starting.
- 💡Double-check that all signage meets regulations.
- 💡Work methodically to avoid rework.
- 💡In practical assessments, always clean connectors and reference test leads before testing. A dirty connector can add 0.5 dB loss, failing the test. Examiners look for this attention to detail.
- 💡When answering theory questions on safety, always reference specific regulations (e.g., 'Under CDM 2015, a risk assessment must be completed before excavation'). Generic answers lose marks.
- 💡For splicing questions, remember to mention the importance of cleave angle (typically <1°) and arc power settings. Examiners want to see you understand the process, not just memorise steps.
Common Mistakes
Common errors to avoid in your coursework
- Failing to adjust segregation measures for changing weather, light conditions, or traffic flows, leading to unsafe situations.
- Incorrect placement of warning signs or barriers, resulting in inadequate advance warning for road users and potential collisions.
- Overlooking the need to regularly inspect and maintain segregation equipment during the work, allowing deterioration or displacement.
- Failing to install advance warning signs at the legislated distances, leading to insufficient reaction time for approaching drivers and potential safety breaches.
- Using cones or barriers without correct reflective sleeves, steady lights during darkness, or not weighting them properly, which can result in them being displaced by wind or passing vehicles.
- Neglecting to include a safety zone or 'shadow vehicle' for high-speed roads, forgetting that the segregation must protect the workforce during the entire operation.
- Not checking for underground services before digging.
- Using incorrect signage or barriers.
- Failing to secure the work area adequately.
- Misconception: Fibre optic cables are fragile and cannot be bent. Correction: While fibre is more delicate than copper, it has a minimum bend radius (typically 10x the cable diameter for installation). Exceeding this causes micro-bends and signal loss, but careful handling allows tight bends in ducts.
- Misconception: All fibre connectors are the same. Correction: Connectors vary (SC, LC, ST, FC) and must match the equipment. Using the wrong connector or poor polishing can cause high insertion loss. Always check the network design specification.
- Misconception: OTDR testing is only for final acceptance. Correction: OTDRs are used throughout installation to verify splices, identify faults, and document the link. Pre-termination testing saves time and materials.
