Unloading the vacuum excavator

When work started on plans to upgrade a suburban street’s gas main connection, contractors needed to draw up a safe system of work.

The planned maintenance involved excavating across the front of each property to access the gas line connectors, and allow engineers to connect new lines.

Contractors knew that the excavations would take days to complete, and that on-site health and safety practices needed to be a priority because of the number of residents on the road.

No-dig solution for safety

The solution to ensure site safety and prevent potential hazards, included calling on us to provide vacuum excavation support. The self-contained suction units allowed each connector to be excavated without creating large piles of ground spoil down the street. The machine’s remote controlled arm lifted away the ground using strong suction power, pulling debris inside the machine to store and unload on site later in the day.

Once utility connections were located and marked up outside each house, the precision control of the vacuum excavator ensured minimum excavation was required, keeping the work area as small as possible, further reducing the risk of incidents on site.

No-dig vacuum excavation to upgrade gas mains

Preventative planning

With safety as the main concern at the planning stage of these upgrade works, contractors also knew that the vacuum excavator’s no-dig approach would also provide a lower risk excavation method. Use of the strong suction boom and on-board air lance to unearth underground lines eliminated the need to manually dig ensuring lines weren’t damaged and no injuries were incurred.

Using the vacuum excavator’s no-dig technology allowed contractors to complete extensive gas upgrade works throughout the street. Project delivery was on time and completed without any health and safety incidents.
