CIAW is the starting point, but planning, payroll, and productivity are the real payoff
Most concrete plant directors associate time registration with one thing: CIAW compliance. And they are not wrong, Belgian law requires electronic attendance registration for ready-mix concrete deliveries that meet certain thresholds, and fines for non-compliance can reach €6,000 per worker per day.
But if compliance is the only reason your plant tracks working hours, you are leaving significant operational value on the table. Digital time registration for concrete plants delivers benefits that directly affect planning accuracy, payroll costs, and decision-making, benefits that have nothing to do with avoiding fines and everything to do with running a better operation.
CIAW and Concrete: The Compliance Baseline
When Does CIAW Apply?
Check in at Work (CIAW) requires daily electronic registration of every worker on a qualifying site. For the concrete sector, the rules depend on the type of activity:
| Scenario | CIAW Required? |
| Ready-mix delivery to a site above €500K threshold | ✅ Yes |
| Delivery to a private residential project below threshold | ❌ No |
| Driver performing finishing work on site (e.g. pumping) | ✅ Yes, qualifies as real estate work |
| Delivery to the plant’s own yard (no construction site) | ❌ No |
| Subcontracted driver delivering on behalf of your company | ✅ Yes, your registration obligation |
CIAW applies when the total value of construction works on a site exceeds €500,000 (excl. VAT). Everyone on site must be registered: own employees, subcontractor workers, temps, and self-employed. Registration must happen before work begins, every day.
Under Belgian chain liability rules, the main contractor can be held responsible for missing registrations from subcontractors in their chain. For a full breakdown of CIAW in the concrete sector, see our dedicated guide.
The 2027 Expansion
From January 2027, mandatory digital time registration will expand beyond current CIAW/CIAO sectors. Concrete plants that invest in digital systems now will be compliant when the new rules take effect, without rushed implementation.
⚠️ Early preparation pays off: Companies that digitise time registration now benefit from immediate CIAW compliance, payroll accuracy, and operational visibility, plus readiness for 2027 without additional effort.
5 Benefits Beyond Compliance
1. Accurate Planning and Resource Allocation
Concrete plants run on tight schedules. A delay of 30 minutes in a pour can cascade through the entire day’s production and delivery plan.
With accurate time registration data, you see exactly how long tasks take, loading, transit, on-site waiting, pouring, return, and plan accordingly. Instead of guessing how many trucks you need tomorrow, you base decisions on actual data. Over time, this eliminates the chronic over- or under-staffing that costs concrete plants thousands of euros per month.
2. Error-Free Payroll From Site to Salary Slip
In most concrete operations, the journey from worked hours to payroll involves at least three manual handoffs: the worker records hours, a supervisor validates them, and HR re-enters them into the social secretariat’s system (SD Worx, Partena, Acerta). Each handoff introduces errors.
Digital time registration eliminates this chain by connecting the clock directly to your payroll export. Hours flow from the plant floor into your HR system without manual re-entry, reducing payroll disputes, late corrections, and the admin time HR spends chasing paper timesheets every month.
3. Real-Time Visibility Across Plants and Sites
If your company operates multiple plants or dispatches teams to different construction sites, you know how difficult it is to answer a simple question: who is where right now?
A digital time registration system gives plant directors a single dashboard showing every worker’s status, clocked in at Plant A, on delivery to Site 3, or marked absent. This visibility helps you respond to last-minute changes and avoid situations where a site is understaffed because no one checked.
4. Productivity Insights That Drive Decisions
Time registration data, collected consistently, becomes a rich source of insight. You can compare turnaround times between plants, identify bottlenecks in your loading process, or track how much time drivers spend waiting on site versus in transit.
For a concrete plant director managing 20–50 trucks, even a 10-minute improvement in average turnaround time translates into one or two additional deliveries per truck per day, which directly affects revenue.
5. Audit-Ready Records Without Extra Admin
When you implement time registration for operational reasons, compliance becomes effortless. A system that captures real-time, GPS-verified working hours for planning and payroll purposes automatically produces the audit-ready records that CIAW and social inspections require.
No more last-minute scrambles before an NSSO inspection. No more reconstructing paper logs. The compliance data is already there because it is the same data you use to run the business.
What This Looks Like in Practice
❌ Before Digital Time Registration
A concrete plant with 35 employees and 18 trucks manages hours through paper timesheets and an Excel overview. Every Friday, the site manager spends 2–3 hours reconciling hours. Payroll discrepancies average 4–6 corrections per month. When an NSSO inspection was announced, the team needed two full days to compile records.
✅ After Digital Time Registration
Workers clock in via a mobile app or vehicle badge. Hours sync automatically to a central platform. The payroll export to SD Worx runs weekly without manual corrections. When the next inspection arrives, the operations manager pulls the report in under 5 minutes.

Frequently Asked Questions
Is time registration mandatory for concrete plants in Belgium?
CIAW registration is mandatory when ready-mix concrete deliveries are made to construction sites where the total project value exceeds €500,000 (excl. VAT). From 2027, a general time registration obligation will apply to all Belgian employers, including concrete companies.
What are the benefits of time registration beyond CIAW compliance?
Digital time registration improves planning accuracy, eliminates payroll errors through direct integration with social secretariats (SD Worx, Partena, Acerta), provides real-time visibility across multiple plants and sites, and delivers productivity insights for fleet optimisation.
Can time registration data integrate with our payroll system?
Yes. Platforms like Suivo offer direct payroll exports to Belgian providers such as SD Worx, Partena, and Acerta, as well as ERP integrations with SAP, Microsoft Dynamics, KPD, and Odoo.
What registration methods work best for concrete plants?
Vehicle badges work well for drivers who start from the plant. Mobile apps suit workers who move between sites. Site poles are effective for fixed locations. Most concrete companies use a combination. For a detailed comparison, see our guide to the best time registration tools in Belgium.
