Excavation Near Underground Services (Potholing) SWMS

Product Overview

This Excavation Near Underground Services (Potholing) Safe Work Method Statement (SWMS) is developed to help workers and PCBUs identify, control, and minimise the risks associated with locating and working around buried utilities and assets. It is a comprehensive, task-specific document that addresses multiple aspects of potholing, service locating, and excavation near underground services to support WHS compliance and prevent underground services strikes.

Activities & Specific Tasks Covered

This document includes specific risk controls for:

  • Planning and preparation for excavation works in the vicinity of underground services, including review of Dial Before You Dig and service plans
  • Inspecting and assessing the work area for underground services, surface clues, and potential conflict with existing assets
  • Underground utility checks in treed landscapes, including managing root systems and hidden service routes
  • Potholing excavation methods to safely expose buried services using hand tools, vacuum excavation, or other low‑impact techniques
  • Excavating near underground services and assets while maintaining minimum approach distances and protective measures
  • Groundworks in the vicinity of underground services, including trenching, backfilling, and compaction around exposed utilities
  • Control measures to prevent damage to underground utilities during excavation, including mechanical plant exclusion zones and spotters
  • Managing potential damage to utilities, including immediate response, isolation, and notification procedures
  • Drilling into subsurface to install or locate services, with controls to avoid striking pipes, conduits, or cables
  • Excavating to install new services while protecting existing pipework, cabling, and associated infrastructure
  • Unearthing hidden pipe work and other unknown services, including safe exposure, identification, and support
  • Dealing with unexpected finds such as buried objects, unknown services, or contaminated materials
  • Reacting to buried artefact discoveries, including stop‑work, securing the area, and notification of relevant authorities
  • Underground services strike prevention, including use of service locators, permits, and supervision of plant operators
  • Working close to buried services, including safe use of hand tools, mechanical equipment, and barriers to protect assets and workers

Who is this for?

This SWMS is designed for civil contractors, plumbers, electricians, utility installers, landscapers, service locators, and site supervisors involved in any excavation or potholing work near underground services on Australian worksites.
