Excavations
Ground assessment, collapse prevention, edge loading, water, access, inspection and emergency 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
Excavations need competent planning for ground conditions, support or battering, services, water, access and adjacent structures.
Exam cue: Control entry with safe access and edge protection.
Concept 2
Spoil, plant and materials must not overload edges or enter collapse and fall zones.
Exam cue: Review after rain, vibration, impact or support change.
Concept 3
Inspection is required at suitable times and after events that could affect stability.
Exam cue: Plan rescue without uncontrolled entry.
