Underground and Overhead Services
Information, detection, marking, safe digging, clearance, goalposts, isolation and change control.
How to prepare for SMSTS
Connect each legal and technical topic to a manager's planning, communication, verification and learning decisions, then practise the resource-timing and two-mark focus-area boundaries.
Core concepts
Concept 1
Plans provide a starting point; competent location and safe excavation methods confirm buried services.
Exam cue: Use records, locating equipment and careful exposure together.
Concept 2
Overhead-line planning uses avoidance, isolation where possible, safe clearances, barriers and controlled routes.
Exam cue: Control plant dimensions and attachments near overhead lines.
Concept 3
Service information and controls must be updated when conditions or discoveries differ from the plan.
Exam cue: Stop on an unidentified service.
