Workforce Tracking for EPC Sites
A practical guide for construction and infrastructure teams to implement zone-level workman visibility, attendance automation, and movement reporting.

On large EPC and infrastructure projects, teams need to know where every workman is during the shift, not only who entered the gate in the morning.
Why Large EPC Sites Struggle to Track Workmen in Real Time
Attendance records show who came to the project. They do not show where each person is now. On large EPC sites, that gap creates daily operational and safety problems.
A paper register or manual checking may work for 30-40 workers. With 300-500 workers spread across entry gates, work zones, yards, offices, and exit points, that model stops being reliable.
Why Attendance Alone Is Not Enough
Most sites already use gate registers, biometrics, or ID checks. These systems confirm entry only. After entry, they cannot confirm zone reach, zone duration, assigned supervisor presence, early exits, or last seen position.
For EPC teams, "present/absent" is not enough. Daily decisions require live zone presence and movement history.
- Who is currently at the main work zone?
- Did the assigned person actually reach that zone?
- How long has this workman stayed in a confined area?
- Who left before shift end?
- Where was this person last detected?
Why Manual Tracking Does Not Work on Large EPC Sites
- No live visibility during shifts after gate check-in.
- Assigned zone visits cannot be verified with evidence.
- Emergency headcount becomes estimate-driven.
- Supervision time is lost to calls and physical checks.
- No reliable digital trail for HSE/client audits.
These are system problems, not people problems. Site complexity increased, tracking method did not.
What Actually Fixes This Without Changing Workman Routine
The practical model for large EPC sites is zone-level tracking with BLE ID beacons and fixed IoT gateways.
- Each workman is assigned a small BLE ID beacon.
- Gateways are installed at key movement points and configured zones.
- Entry/exit is logged automatically based on gateway detection.
- Data appears in Aether Portal in real time.
- No app, no tapping, no manual scan, no routine change for workmen.
For most workman tracking requirements, EYE Beacon + FMB125 is sufficient and provides attendance, zone visits, movement history, and summaries.
What If Tracking Is Needed Without Fixed Gateway at Every Stop?
For site engineers, safety officers, and project managers who move across changing locations, GH5200 can be used as an optional personal tracker.
- No fixed gateway needed for that person.
- Direct cloud upload over 2G SIM.
- Complete movement path on map.
- Man-down detection, SOS buttons, and two-way voice support.
This is an optional add-on based on project requirement. Both approaches run on the same Aether Portal.
What About Tunnels and Enclosed Areas?
GPS is often unreliable in tunnels, shafts, basements, and covered work zones. BLE zone tracking does not depend on GPS. Gateways detect nearby beacons locally and log zone presence. For longer enclosed stretches, additional gateways can be placed to maintain coverage continuity.
How Aether Helps Workforce Tracking for EPC Sites
Aether converts detection events into daily operational clarity:
- Live zone-wise presence and headcount.
- Automatic attendance with first in, last out, and total duration.
- Proof of assigned-zone presence via zone visit records.
- Complete day summary for review and reporting.
- Timestamped movement log for audits and incident investigations.
| Report | What the team checks |
|---|---|
| Attendance Report | Entry/exit timing and on-site duration by person. |
| Zone Visit Report | Zone-wise and person-wise time spent by zone. |
| Movement Report | Every entry/exit event with timestamp and zone. |
| Summary Report | Combined daily view of entry, exit, and zone durations. |
| Entry Gate Only | Gate-level in/out checks for daily headcount. |
| Track Report | Movement and last known map position for selected user/time. |
What to Plan Before Deployment
- Register workers in portal before beacon assignment.
- Attach beacon to always-carried item (helmet/ID/vest).
- Plan stable power at every gateway location.
- Validate gateway placement with on-site walkthrough.
- Confirm practical detection range under actual site conditions.
Is This the Right Fit?
This approach is specifically useful when you need zone-level visibility across multiple active areas, verified assigned-zone presence, reliable live headcount, and audit-ready digital records from one portal.
It is not metre-by-metre consumer GPS tracking. It is operationally reliable zone-level presence and movement visibility designed for EPC execution reality.

Frequently Asked Questions
What if a worker forgets or loses their beacon?
The portal shows non-detected users for the day. Beacons can be reassigned quickly, and teams usually keep spare units.
Can direct workers and subcontractor teams be tracked separately?
Yes. Worker groups can be registered and filtered separately in portal views and reports.
Can more zones be added later?
Yes. Additional gateways can be installed and new zones configured without disrupting existing setup.
How long does setup take on a new project?
After gateway installation and beacon assignment, the system is ready. No app or Wi-Fi dependency for daily operation.
Can this replace manual attendance?
It significantly reduces manual effort through automatic entry/exit and duration records; some projects run both during early rollout.
What if two gateways detect the same beacon?
The system uses strongest and latest signal logic to assign the active zone during overlap conditions.
