Three registration methods, one goal, but which one fits your concrete operation?
Time registration in the concrete sector is fundamentally different from a typical construction site. Drivers cycle through multiple deliveries per day. Plant workers operate in dusty, wet environments where touchscreens struggle. Dispatchers need real-time visibility into who is where, and CIAW compliance must be maintained across both plant and delivery locations.
The question is not whether you need digital time registration, regulatory requirements and operational efficiency demand it. The question is which registration method best fits your operation: a mobile app, NFC badges, or fixed site poles? Each has distinct advantages and limitations, and the right choice depends on your workforce, your sites, and your workflows.

Why the Concrete Sector Has Unique Registration Challenges
Unlike a fixed construction site where workers arrive in the morning and leave in the evening, concrete operations involve constant movement. A typical ready-mix driver may visit 4 to 8 delivery sites per day. Plant workers transition between loading areas, batching stations, and maintenance zones. Temporary workers and subcontracted drivers rotate frequently.
This creates several specific challenges:
| Challenge | Impact on Time Registration |
| Drivers visit multiple sites daily | Registration must be fast (<10 seconds) and repeatable |
| Harsh plant environment (dust, moisture, vibration) | Hardware must be ruggedised; touchscreens may fail |
| Mixed workforce (own drivers + subcontractors) | System must accommodate workers without company accounts |
| CIAW required at delivery sites | Registration must work at remote locations, not just the plant |
| Real-time dispatch visibility needed | Registration data must feed dispatcher dashboards instantly |
| BENOR quality tracking integration | Time data may need to link to delivery note timestamps |
⚠️ CIAW registration is mandatory for concrete deliveries to construction sites that meet the threshold criteria. A driver delivering to a site with 2+ subcontractors must register their attendance, not just at the plant, but at the delivery location.
The Three Registration Methods Explained
Mobile App
A smartphone application that workers use to check in and check out. Typically uses GPS to verify the location and a simple tap or swipe to register. The Suivo app works on both iOS and Android and requires an active mobile data or WiFi connection.
✅ Best for: Drivers who carry a smartphone and visit multiple sites daily.
❌ Less suited for: Plant workers with dirty hands, workers without smartphones, environments where phones are restricted.
NFC Badge
A physical badge or card that workers tap against an NFC reader. The reader is connected to the Suivo platform and records the check-in/check-out event instantly. Badges are durable, waterproof, and require no training.
✅ Best for: Plant workers, fixed locations, high-turnover environments where workers may not have smartphones.
❌ Less suited for: Mobile drivers at remote delivery sites (requires a reader at each location).
Site Pole
A standalone, solar-powered or battery-powered registration device installed at a fixed location. Workers register by tapping a badge or entering a code. Site poles are designed for outdoor, remote, or temporary locations and connect via cellular network.
✅ Best for: Fixed entry points at plants, large construction sites receiving concrete deliveries, locations without WiFi.
❌ Less suited for: Highly mobile operations or situations where the registration point changes frequently.
Head-to-Head Comparison
| Criteria | Mobile App | NFC Badge | Site Pole |
| Speed of registration | 5-10 seconds | < 2 seconds | 3-5 seconds |
| Works at remote delivery sites | ✅ Yes (with mobile data) | ❌ Needs reader on site | ✅ If pre-installed |
| Works in dusty/wet plant conditions | ❌ Touchscreen issues | ✅ Tap only | ✅ Ruggedised |
| Requires smartphone | ✅ Yes | ❌ No | ❌ No |
| GPS location verification | ✅ Built-in | ❌ Reader location only | ✅ Fixed GPS coordinates |
| Cost per worker | Low (software only) | Low (badge + reader) | Medium (hardware unit) |
| Setup complexity | Low | Low-Medium | Medium |
| Subcontractor-friendly | ✅ Download app | ✅ Issue temp badge | ✅ No setup needed |
| CIAW compliant | ✅ Yes | ✅ Yes | ✅ Yes |
| Real-time data to dispatcher | ✅ Instant | ✅ Instant | ✅ Instant |
Which Method Fits Which Role?
In most concrete operations, a single registration method will not cover every scenario. The table below maps common roles to the most effective method.
| Role | Recommended Method | Reasoning |
| Ready-mix driver (own fleet) | Mobile App | Visits multiple sites, has company phone, GPS verifies delivery location |
| Ready-mix driver (subcontracted) | Mobile App or Site Pole | May not have company phone; site pole at plant, app for deliveries |
| Plant operator (batching) | NFC Badge | Fixed location, hands often dirty, no phone needed |
| Plant loader | NFC Badge | Same as batching; fast tap-in at start of shift |
| Maintenance technician | Mobile App | Moves between plant areas, needs flexibility |
| Dispatcher | Dashboard only | Monitors registrations, does not register themselves |
| Temporary worker | NFC Badge or Site Pole | No training needed, no app download required |
“We started with the app for everyone, but quickly realised our plant workers needed badges. Once we combined both, adoption went from 70% to 98% within a month.”— Operations Manager, Belgian concrete plant
The Hybrid Approach: Combining Methods
The most successful concrete operations use a combination of methods tailored to each role and location. Suivo supports all three methods within a single platform, so registration data from apps, badges, and site poles flows into one dashboard.
A typical hybrid setup for a concrete plant with its own fleet:
• Site pole at the plant entrance for all arriving workers and visitors
• NFC badge readers at the batching station and loading dock
• Mobile app for drivers making deliveries to construction sites
• Centralised dashboard for dispatchers and operations managers
This layered approach ensures that no registration is missed, regardless of the worker’s role or location. All data feeds into the same
Suivo time tracking platform, giving dispatchers and managers a single view of their entire workforce.
CIAW Compliance Across All Methods
Regardless of which registration method you choose, CIAW compliance requires that the data is reported to the NSSO (RSZ). Suivo handles this automatically: every check-in event, whether from an app, badge, or site pole, is transmitted to the CIAW system in real time.

For concrete suppliers delivering to construction sites, the CIAW obligation applies at the delivery location, not just at the plant. This is where the mobile app has a clear advantage: drivers can register at any site without requiring pre-installed hardware.
⚠️ From 2027, all Belgian employers will also need to record actual working hours (start, end, breaks), not just attendance. Plan your registration system to support both presence and hours tracking from the start.
Frequently Asked Questions
Can drivers use the app without a company phone?
Yes. The Suivo app can be installed on personal smartphones. However, for consistent adoption, providing a company device or pre-configured tablet in the truck cabin is recommended.
What happens if the site pole loses connectivity?
Suivo’s time registration requires an active connection (WiFi or mobile data) to ensure data integrity. Site poles use cellular connectivity and are placed where signal coverage is available. In areas with weak signal, an external antenna can be added.
How do temporary or subcontracted drivers register?
Temporary workers can register using a guest badge at a site pole or NFC reader, or by downloading the Suivo app. No account creation or IT setup is needed, the system is designed for high-turnover environments.
Can I combine methods within a single site?
Absolutely. Suivo supports any combination of app, badge, and site pole within the same site. All data flows into a single dashboard, so you always have one source of truth.
How does this integrate with our dispatch system?
Suivo offers API integrations with common dispatch and ERP systems used in the concrete sector. Registration data, delivery timestamps, and worker locations can be synchronised automatically.
