Scope of works
This RAMS covers trenching carried out by groundworks operatives on a UK construction or maintenance site. It sets out the method, the principal hazards and the control measures to be applied. Site-specific details (address, client, access, dates and supervisor) are completed for each job before the document is issued for principal-contractor review.

Sequence of works
- 1Obtain and review service drawings; scan and mark the area
- 2Set out exclusion zones and install support/battering as designed
- 3Excavate progressively, hand-digging near located services
- 4Inspect supports and atmosphere before any entry
- 5Backfill and reinstate; remove plant under banksman control

Hazards, risk rating & controls
Risk = likelihood × severity (1–25). Initial is before controls; residual is with controls applied.
Collapse of excavation / trench sides
