Risk Assessment for Excavation on a Construction Site — UK

UK construction-safety guidance by the Riskora Editorial Team

If your next job involves excavation on a construction site, the safety case starts here. Excavation works carry one of the highest fatality rates in UK construction, driven by collapses, service strikes, and falls into open trenches. For excavation on a construction site specifically, CDM 2015 requires the construction phase plan to address excavation risks. The right Risk Assessment pulls all of this together — the law, the site, the people, the controls — into one document that does the job.

When This Document Is Required

CDM 2015 requires the construction phase plan to address excavation risks. The principal contractor must coordinate excavation activities with all other site operations and ensure exclusion zones are maintained.

Common Mistakes to Avoid

Using a generic template without adapting it to the specific excavation activities on active construction sites conditions
Not reviewing the document when site conditions change
Missing sign-off from a competent person before work begins
Failing to consider trench collapse from adjacent plant movements
Not addressing workers falling into unprotected excavations
Not briefing all workers on the document content before work starts

Example Scenario

A self-employed contractor has been asked to produce a Risk Assessment that the project's safety advisor will actually accept first time, rather than the generic template that came back marked up last time. The supervisor opens Riskora on a phone between site visits, selects the preset, checks the pre-populated content against the actual scope, makes the edits the site demands, and has a finished document by the end of the day. The finished document explicitly addresses trench collapse from adjacent plant movements, which the principal contractor would otherwise expect to see written into the pack.
