Who was on site today — including the people who don't work for you.
On a live project the headcount changes every morning, most of it belongs to subcontractors, and the site gate register is a paper book that nobody reconciles until something goes wrong.
The register has to cover people you don't employ.
Mixed workforce
Direct staff, labour contractors and specialist subcontractors, all on the same site on the same day, all needing to appear in the same register.
Sites move
A project's boundary changes as it progresses, and a site that exists this year is gone the next. Fixed infrastructure at the gate is money you write off.
Presence is safety-critical
In an incident, knowing exactly who was inside the boundary is not an administrative nicety. It's the first question anyone asks.
One boundary, one register, everyone in it.
The project becomes a geofence — redrawn whenever the site does, and testable against a coordinate before you roll the change out. Everyone working inside it is assigned to it, whoever signs their pay cheque.
- Redraw the fence as the project moves, and test the new boundary against real coordinates before it goes live.
- Face-verified punches that make it materially harder for one person to sign in a crew of six.
- Contractor staff in the same employee master, scoped and reported alongside direct employees.
- Live "on site now" view — the number, and the names, at any moment.
- On-duty requests for legitimate work away from the boundary, approved rather than assumed.
- Overtime claimed and approved before payroll, so late finishes are authorised rather than argued about.
- Immutable audit trail — the record of who was inside the fence is not something anyone can quietly revise afterwards.
One project, four hundred people.
06:30 — gate rush
Everyone punches on their own handset as they arrive. No queue at a single terminal, no bottleneck at the one thing that can break.
09:00 — the count
The site manager opens the live view: who is inside the boundary right now, broken down by contractor.
18:40 — late finish
A crew works past the shift. Overtime is claimed, routed to the approver, and either authorised or not — before it reaches payroll.
Month end — reconciliation
Contractor invoices are checked against the attendance record instead of against a paper register nobody wants to defend.
Test it on your most complicated site.
The one with the most subcontractors and the most awkward boundary. That's where an attendance system either works or doesn't.
