Install equipment for safe working on the highway for utilities network construction
This subtopic covers the practical installation of temporary traffic management equipment, including signs, lighting, and guarding, to ensure safe working on the highway during utilities network construction. It focuses on compliance with industry Codes of Practice (such as the Red Book) and current legislation, while also addressing resource preparation, data interpretation, and problem-solving in dynamic roadside environments. Mastery ensures operatives can protect themselves, colleagues, and the public, maintaining traffic flow and minimising disruption.
Assessment criteria
Topic Overview
The City & Guilds Level 2 Diploma in Network Construction Operations (Gas) - Main layer focuses on the skills and knowledge required to install, maintain, and repair gas mains and service pipes. This qualification is essential for those working in the gas distribution industry, covering everything from excavation and pipe laying to jointing and testing. It ensures that operatives can work safely and competently on low and medium pressure gas networks, adhering to industry standards and regulations.
This diploma is part of the wider Construction & Building Services sector, specifically within the gas distribution pathway. It builds on basic health and safety principles and introduces specialised techniques for working with polyethylene (PE) and ductile iron pipes. Understanding this topic is crucial for ensuring the safe and reliable supply of gas to homes and businesses, and it forms the foundation for career progression to higher-level supervisory or technical roles in the gas industry.
Key Concepts
Core ideas you must understand for this topic
- →Safe excavation practices: including CAT scanning, digging by hand near services, and shoring to prevent collapse.
- →Pipe jointing techniques: electrofusion and butt fusion for PE pipes, and mechanical joints for ductile iron.
- →Pressure testing and purging: ensuring system integrity before commissioning.
- →Understanding gas network classifications: low pressure (LP), medium pressure (MP), and associated safety zones.
- →Permit to work systems and risk assessments: essential for controlling hazards on live gas mains.
Learning Objectives

- Prepare and inspect all required resources, including signs, cones, and barriers, before deployment
- Apply the principles of the Safety at Street Works Code of Practice during equipment installation
- Demonstrate effective use of communication protocols to coordinate with team members and road users
- Identify and resolve common problems, such as vehicle conflicts or pedestrian access issues, arising during equipment setup
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating correct positioning and sequencing of temporary signs, cones, and barriers in accordance with the relevant chapter of the Traffic Signs Manual.
- Assess performance on ability to interpret site-specific information (e.g., daily job sheets, risk assessments) to select and allocate appropriate resources before highway works commence.
- Evaluate evidence of systematic defect checks on lighting and guarding equipment, with prompt reporting and isolation of faulty items.
- Look for effective communication with team members and other road users using agreed signals or radio protocols when adjusting equipment in response to changing traffic conditions.
- Award credit for correct sequencing: placing advanced warning signs before taper cones
- Look for evidence of equipment checks prior to installation, e.g., clean, reflective, and undamaged signs
- Assess adherence to specified distances for sign placement as per the Code of Practice
- Credit clear communication demonstrated through verbal briefings or use of two-way radios
- Evaluate the learner’s ability to justify positioning decisions with reference to legislation
- Check that temporary lighting is correctly positioned to illuminate the work area without dazzling road users
Assessment Guidance
Guidance for achieving higher grades
- 💡When answering scenario-based questions, always reference the specific Code of Practice (e.g., 'in line with the Red Book, the 450mm taper is required…') to demonstrate contextualised knowledge.
- 💡For practical assessments, verbalise your risk assessment thought process as you install each item, showing the assessor you are constantly evaluating dangers like proximity to live traffic or overhead services.
- 💡Use the ABC of temporary traffic management (Advance warning, Buffer zone, Coning scheme) as a mental checklist to ensure no critical step is missed during setup or removal.
- 💡Always reference the relevant sections of the Safety at Street Works Code of Practice in your answers
- 💡Use the ‘Plan, Do, Review’ model to structure practical demonstrations and written responses
- 💡Be specific with terminology: say 'Chapter 8 compliant barriers' not just 'barriers'
- 💡Show a systematic check of equipment before use, verbally or in writing, to evidence thoroughness
- 💡When approaching problem-solving scenarios, consider all road users and surrounding environment impacts
- 💡Always reference current regulations (e.g., IGE/TD/3 for gas mains) in your answers to show you understand the legal framework.
- 💡When describing a procedure, use the correct sequence: risk assessment, excavation, pipe laying, jointing, testing, and reinstatement. Missing steps loses marks.
- 💡Know the difference between a service pipe and a main, and be able to explain the pressure tiers (LP, MP, IP, HP) and their typical applications.
Common Mistakes
Common errors to avoid in your coursework
- Forgetting to check the condition and functionality of portable traffic lights (e.g., lamps, batteries) before deployment, leading to mid-shift failures.
- Placing advance warning signs at incorrect distances from the works area, often too close, which compromises driver reaction time and breaches the Safety at Street Works Code of Practice.
- Neglecting to secure cones or signs in windy conditions, risking them blowing into live traffic lanes and creating hazards.
- Confusing the different classes of pedestrian barriers and their specific applications, resulting in inadequate protection for vulnerable road users.
- Installing warning signs too close to the works area, reducing reaction time for drivers
- Failing to secure cones and barriers against wind or vehicle wash, causing displacement
- Using incorrect or generic equipment not compliant with Chapter 8 specifications
- Neglecting to consider vulnerable road users, such as cyclists or pedestrians, in the setup
- Misinterpreting site plans, leading to incorrect lane closures or inadequate safety zones
- Misconception: You can use any type of pipe for gas mains. Correction: Only approved materials like PE80/PE100 or ductile iron with appropriate coatings are permitted, and they must meet specific standards (e.g., BS EN 1555).
- Misconception: Excavation depth doesn't matter as long as the pipe is covered. Correction: Depth must comply with national standards (e.g., minimum 750mm cover in footpaths, 900mm in roads) to protect against damage and frost.
- Misconception: Pressure testing is only needed after installation. Correction: Testing is required at multiple stages, including after jointing and before backfilling, to ensure no leaks.
