Remarking and revalidation
Protecting on site markings is crucial.
If initial markings done by underground infrastructure owners are no longer visible, you must notify them at once.
If your excavation work extends the 30 day period, you must have your locate request revalidated.
Validity of a request
Your request is valid until the end date of the work written on your request. By revalidating the request, you extend its validity until the new end date of work written on the request.
If your request was initially completed 6 months ago, you must place a new locate request.
