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.

Where this comes from

Checked September 24, 2026 against the one-call center's published copy of the law, because the legislature's own site couldn't be read directly. Rules change; confirm with the center before a big job.
