Any excavation or digging on a Job site will require the location of underground utilities and services.

Natural gas, electricity, water and sewer lines buried in the ground pose a hazard for digging with heavy equipment or by hand.

In Canada, the "Call Before You Dig" service provides free locates to map out where these underground lines are running, marked with surveyor flags or painted lines.

If the retrofit work you're doing involves excavating around an existing building, you must call to have these locates done.
