Permit to Dig Process

• Obtain a permit to dig before starting any ground disturbance operation
• Review utility service plans for the area and mark known services on site
• Scan the dig area with CAT and Genny equipment and record the findings
• Specify hand dig zones and mechanical exclusion distances on the permit
• Brief the excavator operator and ground workers on the permit conditions
• Keep the permit available at the point of work throughout the operation
• Re-issue the permit if the dig location, depth, or method changes
• Record the permit number, date, and names of issuer and acceptor
• Include emergency strike procedures on the permit for quick reference
• Close out the permit formally when the excavation work is complete

• DON'T dig without a valid permit to dig in place and signed off
• DON'T accept a permit if you have not been briefed on its conditions
• DON'T rely on the permit alone — always scan with CAT and Genny before digging
• DON'T extend the dig beyond the area shown on the permit without re-issue
• DON'T use mechanical excavation within the restricted zone of known services
• DON'T assume old permits are still valid — check the expiry date
• DON'T allow operatives without permit training to issue or accept permits
• DON'T ignore unmarked services found during the dig — stop and re-assess
• DON'T leave the permit in the site office — it must travel with the work
• DON'T continue digging if the conditions described on the permit have changed
