How long the ticket or marks last

Keep power equipment at least 18 inches from the marks.

Running several digs at once?

TrackOver keeps each ticket number, markout date and expiry on the job it belongs to, and warns before a ticket runs out, so the crew in the hole isn't digging on a dead ticket.
