Site Operations covers the work that happens on the ground every day: Start a Prestart, New Timesheet, New Shift Report and Team Approvals.
These are the pages your crews and supervisors live in day to day. On a phone, the Today card on the Dashboard is the quickest way into them.
Prestarts and timesheets also work with no signal, from Offline forms under My Workspace. Shift reports do not: they need signal.
