Ground movement, vibration and pressure limits near buried cables
NS193: Ground movement, vibration and pressure limits near buried cables
This standard sets the acceptable ground movement, vibration and pressure limits for Ausgrid’s buried electrical cables.
Scope
This standard sets the acceptable ground movement, ground vibration and ground pressure limits for Ausgrid’s buried electrical cables to prevent damage to Ausgrid’s assets due to major site works by other organisations.
This standard is intended to apply to major projects such as tunnels, deep excavations, major roadworks, piling works, rock breaking, large mobile crane loads etc. It does not apply to conventional trenching, road re-surfacing or minor works near Ausgrid’s buried cables.
This standard does not deal with the requirements for major excavation works near or below Ausgrid’s substation assets. For these projects, early contact shall be made with Ausgrid to establish the specific requirements for ground movement, ground vibration and ground pressure control near substation assets.
