Mason · Belgium
1. Executive Summary
Masonry is classified as a permanent shortage occupation (Knelpuntberoep) across all three Belgian regions — Flanders, Wallonia, and Brussels — making it one of the most accessible trades for non-EU workforce deployment via the Single Permit route. Belgium has a deep cultural attachment to brick construction, with complex Flemish Bond facades and restoration work as standard expectations. The trade falls under PC 124 (Construction Joint Committee) with automatic quarterly wage indexation. Belgium’s large pre-war housing stock drives high renovation demand, particularly for facade restoration. The dominant deployment route remains posted workers (Detachering), but social dumping enforcement targeting posted masons is the most aggressive in the EU.
Belgium is a federal civil-law state in which immigration competence is split: the federal government retains residence (séjour / verblijf) authority through the Office des Étrangers / Dienst Vreemdelingenzaken, while economic migration (work authorisation, salary thresholds, shortage occupation lists) sits with the three regions: Flanders (Vlaanderen), Wallonia (Wallonie) and Brussels-Capital (Bruxelles-Capitale / Brussel-Hoofdstad). The German-speaking Community (East Cantons) holds devolved authority over a small number of municipalities adjacent to the German border.
Regulatory documents are tri-lingual (Dutch, French, German). Federal law is published in the Moniteur belge / Belgisch Staatsblad and indexed at https://www.ejustice.just.fgov.be. Regional decrees appear in the same bulletin under regional headers. The civil-law tradition means legislation is exhaustively codified; the Code judiciaire, Code pénal social, Code du bien-être au travail and the Loi du 12 avril 1965 form the working spine for any cross-border construction deployment.
Inspection competence is layered. The Service de l’inspection sociale / Sociale Inspectie audits social-security compliance, posted-worker declarations and chain-liability obligations. The Inspection du Bien-être au travail / Toezicht Welzijn op het Werk, sitting under the SPF Emploi (Service Public Fédéral Emploi, Travail et Concertation sociale), enforces occupational health, safety and the Code du bien-être. Regional labour inspectorates (Departement Werk en Sociale Economie in Flanders; Office Wallon de la Formation Professionnelle et de l’Emploi in Wallonia; Bruxelles Économie et Emploi in Brussels-Capital) audit work-permit compliance.
For non-EU construction deployments, three regimes operate concurrently: (a) the Single Permit (Toelating tot arbeid / Permis unique) for direct hires; (b) the Posted-Worker regime under the Loi-programme (I) du 27 décembre 2006 plus the LIMOSA declaration; (c) the Intra-Corporate Transferee track under Directive 2014/66/EU as transposed in 2017. Each route triggers a different combination of regional, federal and joint-committee obligations.
Trade-specific context
The mason (bricklayer) trade for the purposes of this brief covers the wet-trade specialism of laying mortared brick, block, and dressed-stone walling on residential, commercial, institutional, and light-industrial buildings. Core competencies include setting out coursework, mixing and applying mortars conforming to EN 998-2, laying clay and calcium-silicate brickwork to EN 771-1 and EN 771-2, concrete blockwork to EN 771-3, AAC blockwork to EN 771-4, natural stone walling to EN 771-6, dressed and rubble stonemasonry, parging, pointing, and the construction of masonry retaining elements within building envelopes. The mason interfaces with damp-proof course installation, wall-tie placement (EN 845-1), lintel bedding, and movement-joint detailing.
This trade is distinguished from three adjacent specialisms that Bayswater treats as separate rubrics. Civil_mason (referred to in some jurisdictions as “heavy-civils mason” or “infrastructure mason”) covers retaining-wall construction outside the building envelope, bridge abutments, gabion installation, and civil concrete formwork support; the work product sits under EN 1997 (Eurocode 7 — geotechnical) rather than EN 1996. Concrete_finisher covers cast-in-place concrete surface work — power-floating, troweling, screeding to EN 13670 — and does not involve mortared joints. Carpenter_shuttering (Schalungszimmerer / coffreur) covers formwork carpentry for in-situ concrete and is a distinct apprenticeship pathway in DE, AT, FR and BE. Mason rubrics should reject candidates whose verifiable site experience is predominantly cast-in-place concrete or formwork carpentry.
2. Legal & Regulatory Framework
Primary Legislation
- Codex over het Welzijn op het Werk — workplace safety, scaffolding requirements, manual handling.
- PC 124 Collective Agreement — wages, working conditions, mandatory benefits.
- Article 30bis RSZ Law — chain liability for social debts.
- Royal Decree on Temporary and Mobile Construction Sites — safety coordination.
Regulatory Bodies
| Authority | Function |
|---|---|
| FPS Employment (FOD WASO) | Labour standards, social inspection |
| Constructiv | Sector fund, skills recognition, safety training |
| DWSE / SPW / Brussel Economie | Regional work permits |
| DVZ | Federal immigration |
| SIOD | Social fraud investigation (highest focus on masonry) |
Regional Competency Split
Work permits: regional. Immigration: federal. PC 124: national. “Metselaar” is on the shortage list in all three regions (VDAB, Forem, Actiris) — a rare distinction that simplifies deployment planning regardless of project location.
Belgium is a federal civil-law state in which immigration competence is split: the federal government retains residence (séjour / verblijf) authority through the Office des Étrangers / Dienst Vreemdelingenzaken, while economic migration (work authorisation, salary thresholds, shortage occupation lists) sits with the three regions: Flanders (Vlaanderen), Wallonia (Wallonie) and Brussels-Capital (Bruxelles-Capitale / Brussel-Hoofdstad). The German-speaking Community (East Cantons) holds devolved authority over a small number of municipalities adjacent to the German border.

Regional decrees appear in the same bulletin under regional headers. The civil-law tradition means legislation is exhaustively codified; the Code judiciaire, Code pénal social, Code du bien-être au travail and the Loi du 12 avril 1965 form the working spine for any cross-border construction deployment.

For non-EU construction deployments, three regimes operate concurrently: (a) the Single Permit (Toelating tot arbeid / Permis unique) for direct hires; (b) the Posted-Worker regime under the Loi-programme (I) du 27 décembre 2006 plus the LIMOSA declaration; (c) the Intra-Corporate Transferee track under Directive 2014/66/EU as transposed in 2017. Each route triggers a different combination of regional, federal and joint-committee obligations.
3. Immigration Pathways
Single Permit (Gecombineerde Vergunning)
Because “Metselaar/Maçon” is on the shortage list in all three regions, the labour market test is waived.
- Application: Employer to regional authority.
- Salary: Must meet PC 124 minimum for the assigned category.
- Processing: 2-4 months (bottleneck fast-track).
- Result: Combined work + residence permit.
Posted Workers (Detachering)
The dominant route for cross-border masonry deployment. Critical compliance requirements:
| Requirement | System | Deadline |
|---|---|---|
| Limosa declaration | socialsecurity.be | Before first working day |
| A1 certificate | Home country authority | Before posting |
| Dimona declaration | RSZ/ONSS portal | Before employment start |
| Check-In@Work | QR scan | Daily |
| Construbadge | Constructiv | Before site access |
Critical: Posted masons must receive PC 124 wages (minimum €20.62/hour for Cat III), NOT the minimum wage of the posting country (Poland, Romania, Portugal, etc.). This is the single most inspected compliance point for masonry in Belgium.
EU/EEA Free Movement
No work permit required. Commune registration within 3 months. Limosa required for posted EU workers.
4. Professional Recognition & Certification
Qualification Categories (PC 124)
| Category | Title (NL/FR) | Competence | Typical Role |
|---|---|---|---|
| Cat I | Handlanger / Manoeuvre | Unskilled | Material carrying, mortar mixing |
| Cat II | Geschoolde / Ouvrier Qualifié | Skilled | Standard brickwork, blockwork |
| Cat III | Geschoolde 1e / Qualifié 1er échelon | Advanced skilled | Flemish Bond facades, complex patterns |
| Cat IV | Geschoolde 2e / Qualifié 2ème échelon | Expert/Team leader | Restoration, heritage work, team supervision |
Skills Recognition
Belgium does not operate a formal trade card system for masons. Competence recognition is handled through:
- Constructiv: Can recognise foreign qualifications, but typically verification is done through practical on-site assessment.
- Employer assessment: The employer assigns the PC 124 category based on demonstrated skill.
Certifications
| Certification | Requirement |
|---|---|
| VCA-Basis | Highly recommended; required by most main contractors |
| Constructiv registration | Mandatory for sector fund benefits |
| Medical fitness | Annual certificate required |
Belgian Masonry Standards
- Flemish Bond: Complex decorative facade brickwork is standard, not optional. Foreign masons must demonstrate competence with this style.
- Renovation expertise: Belgium’s old housing stock means restoration work (facade repair, repointing, heritage brickwork) is a major component of demand.
Trade-specific context
The pan-European technical baseline rests on the Eurocode 6 family — EN 1996-1-1 (general rules), EN 1996-1-2 (fire), EN 1996-2 (design considerations) and EN 1996-3 (simplified calculation) governing the structural design of masonry. See https://www.cencenelec.eu/ and the standard catalogue at https://standards.cencenelec.eu/. Mortar specification follows the EN 998 series (EN 998-1 rendering/plastering mortar, EN 998-2 masonry mortar) and unit specification follows EN 771-1 to EN 771-6 (clay, calcium-silicate, aggregate-concrete, AAC, manufactured-stone, natural-stone units). Ancillary components — wall ties, straps, hangers — are governed by EN 845-1, EN 845-2, EN 845-3. Test methods sit under EN 1052 (masonry assemblies) and EN 1015 (mortar test methods). The CEN catalogue is searchable at https://standards.cencenelec.eu/dyn/www/f?p=205:105:0.
Country-specific certifications are well established. DE issues the Maurer Gesellenbrief on completion of three-year duale Ausbildung under BBiG, with Meisterbrief via HWK examination (https://www.hwk.de/) and the trade is enumerated in HwO Anlage A (https://www.gesetze-im-internet.de/hwo/anlage_a.html). FR uses CAP Maçon (RNCP code 4434), BP Maçon, and BAC PRO Technicien du Bâtiment, registered at https://www.francecompetences.fr/ and detailed in the Code du travail at https://www.legifrance.gouv.fr/. NL vakopleiding Metselaar runs through Bouw & Infra Park / SBB (https://www.s-bb.nl/) and almost all sites require VCA Basis or VCA VOL (https://www.ssvv.nl/vca/). BE (Flanders) runs Construct/Constructiv qualification (https://constructiv.be/) and Wallonia uses Forem brevets — both jurisdictions reference the bilingual royal decrees at https://www.ejustice.just.fgov.be/. DK Svendebrev is issued under Bekendtgørelse om erhvervsuddannelser (https://www.retsinformation.dk/eli/lta/2024/214). NO Murer-fagprøve sits under Fag- og yrkesopplæringen and the trade list at https://lovdata.no/. IE uses the SOLAS Bricklayer Apprenticeship (Code 09) coupled with CSCS Construction Skills Certification Scheme (https://www.cif.ie/). ES issues the Tarjeta Profesional de la Construcción (TPC) via Fundación Laboral de la Construcción (https://www.trabajoenconstruccion.com/). AT Befähigungsnachweis is governed by GewO §94 and Anlage 1 (https://www.ris.bka.gv.at/Bundesrecht/). CH uses the Eidgenössisches Fähigkeitszeugnis (EFZ) Maurer/Maçon under SBFI (https://www.sbfi.admin.ch/) with site classification under the LMV Lohnklasse system.
5. Social Security & Insurance
Contribution Structure
| Component | Employer Rate | Employee Rate |
|---|---|---|
| RSZ/ONSS base contribution | ~25.00% | 13.07% |
| Constructiv sector supplement | ~9.12% | — |
| Holiday fund (Verlofkas) | 15.38% | — |
| Work accident insurance | ~2.5-3.5% | — |
| Approximate total employer burden | ~52-53% | 13.07% |
Key Mechanisms
- Holiday pay: Via Verlofkas (15.38% of annual gross), not employer-paid.
- Fidelity stamps: ~9% annual loyalty bonus through PDOK/OPOC.
- Bad weather fund (Weerverlet): Compensation when masonry stops due to rain, frost, or extreme temperatures. Critical for this trade.
- A1 exemption: Posted workers with valid A1 pay social security in home country. Belgian wages mandatory.
Rain Day Rules (Weerverlet)
Under Belgian law, masonry work stops in rain, frost (below 0°C), and extreme wind. Posted workers who attempt to work through stoppages generate union complaints and inspection triggers. The Weerverlet fund compensates workers for lost hours.
6. Wages & Collective Agreements
Applicable Agreement
PC 124 (Joint Committee for Construction).
Wage Scales (2025 Indexed Estimates)
| Category | Minimum Hourly Rate | Typical Market Rate |
|---|---|---|
| Cat I (Helper) | €17.89 | €18.00 - €19.00 |
| Cat II (Standard mason) | €19.39 | €20.00 - €21.00 |
| Cat III (Skilled mason) | €20.62 | €22.00 - €24.00 |
| Cat IV (Master/restoration) | €21.89 | €24.00 - €27.00 |
Supplements
- Automatic indexation: Quarterly (~3.5%/year).
- 13th month: 8.33%.
- Eco-cheques: ~€250/year.
- Mobility allowance (Mobiliteitsvergoeding): ~€0.1579/km, tax-free, mandatory.
The Belgian wage system has three layers: the federal floor (RMMMG), the joint-committee CCT scale and the company-level agreement (where one exists).
Revenu minimum mensuel moyen garanti (RMMMG / GGMMI). The interprofessional minimum, set by CCT 43 of the Conseil National du Travail. Indexation applies twice yearly under the health-index mechanism; structural increases are negotiated in inter-professional accords. As of 1 February 2026, indexation of approximately 2% lifted the RMMMG. From 1 April 2026, a structural EUR 35 gross monthly increase brings the RMMMG to EUR 2,189.81 gross per month for a full-time 38-hour week (CNT — https://cnt-nar.be/fr/dossiers-thematiques/salaire-minimum).
CCT 124 (Construction) wage scale. The construction sector operates a five-class scheme plus foreman levels:
- Class I — entry (manoeuvre / hulparbeider): unskilled or under 6 months tenure
- Class IA — qualifying entry: progresses to Class II within 6-24 months
- Class II — qualified blue-collar (geschoolde): trade-trained worker with assigned work scope
- Class IIA — confirmed qualified
- Class III — first-grade specialist
- Class IV — second-grade specialist (heavy-trade, complex assembly)
- Foreman / chef d’équipe — supervisory grades above Class IV
The CCT 124 base hourly rate for Class I in 2026 stands at approximately EUR 18.231 gross per hour [verify final indexed figure]; Class II commonly sits at approximately EUR 19.40-19.60 gross per hour [verify], with Class IV reaching approximately EUR 22.00-22.50 gross per hour. The full quarterly indexation chronicle is published by FEDERALE Verzekering and the joint-committee secretariat (https://www.lacsc.be/docs/default-source/acvbie-cscbie-document/sectoraal-sectoriel/bouw-construction/). Index revaluations occurred at 0.21859% in January 2026; further revaluations follow the health-index trigger mechanism through the year.
Indexation mechanism. Belgian wages adjust automatically through the health index — a consumer price index excluding tobacco, alcohol and motor fuel. The wage-norm law (Loi du 26 juillet 1996) caps negotiated increases above indexation; for the 2025-2026 period the wage norm was set at 0%, meaning real-terms wage increases above index are prohibited at sector level.
2026 CCT 124 indicative monthly bands (38h/week, gross). Class I approximately EUR 3,000-3,050; Class II approximately EUR 3,200-3,250; Class IV approximately EUR 3,600-3,700; foreman approximately EUR 4,000-4,200 [verify all bands against quarterly chronique].

7. Accommodation & Welfare
Cost by Region
| Region | 1-Bedroom Rent | Shared Housing |
|---|---|---|
| Antwerp | €900 - €1,200 | €400 - €600 |
| Brussels | €850 - €1,100 | €400 - €550 |
| Ghent | €750 - €1,000 | €350 - €500 |
| Wallonia | €550 - €750 | €300 - €400 |
Cost of Living
Belgium has high taxes (40-50% income tax) and high cost of services. Using the Single Permit means paying Belgian social security (~13.07% employee share). Net income for a Cat III mason: approximately €2,000-€2,400/month.
8. Language Requirements
Regional Split
| Region | Language | Masonry Reality |
|---|---|---|
| Flanders | Dutch | Mandatory; no English on residential sites |
| Wallonia | French | Mandatory |
| Brussels | Dutch + French | French dominant |
Technical Vocabulary
| English | Dutch | French |
|---|---|---|
| Brick | Baksteen | Brique |
| Mortar | Mortel / Specie | Mortier |
| Flemish bond | Vlaams verband | Appareil flamand |
| Pointing | Voegen | Rejointoyer |
| Cavity wall | Spouwmuur | Mur creux |
| Lintel | Latei | Linteau |
| Scaffold | Stelling | Échafaudage |
| Spirit level | Waterpas | Niveau à bulle |
| Plumb line | Schietlood | Fil à plomb |
Belgium imposes no statutory CEFR threshold for construction work. Language obligation is regional and operational rather than nominal:
-
Flanders. Dutch is the regional administrative language. Site documentation, briefings and emergency signage must be in Dutch. The Decreet betreffende het taalgebruik (Decree of 19 July 1973, as amended) makes Dutch mandatory for employer-employee communication where the employer’s place of operations is in the Dutch-speaking region.
-
Wallonia. French is the regional administrative language. Equivalent regulatory framework under the Décret du 30 juin 1982 sur la protection de la liberté d’usage des langues françaises.
-
Brussels-Capital. Bilingual French / Dutch. Site language follows the contractor’s working language; safety briefings must be available in both.
-
East Cantons. German is the regional administrative language. Construction sites operate predominantly in German with French as fallback.
Construction radio communications and toolbox-talks must be in the regional language for safety-critical instructions; this is enforced through Code du bien-être au travail Livre VI obligations on comprehensible information rather than through a discrete language statute. A site lead conducting briefings exclusively in English on a Flemish or Walloon site is a recognised compliance failure during inspection.
VCA Veiligheidspaspoort. The VCA (Veiligheid, gezondheid en milieu Checklist Aannemers) certification is the de facto safety passport for the Belgian construction sector. While not federally mandated, principal contractors in Flanders almost universally require VCA-Basis (B-VCA) for blue-collar workers and VCA-VOL for supervisors. The Veiligheidspaspoort itself costs EUR 14.50 excluding VAT (BESACC-VCA — https://www.besacc-vca.be); B-VCA exam fees are typically EUR 72-98 in 2026, VOL-VCA EUR 92-113, with full training packages priced around EUR 260 [verify range]. Exams are available in Dutch, French, English and German.
9. Compliance & Enforcement
Enforcement Bodies
| Agency | Focus |
|---|---|
| SIOD | Social fraud — masonry is the #1 target |
| RSZ/ONSS | Social security, Check-In@Work |
| FPS Employment | Wages, posted worker compliance |
| Federal Police | A1 certificate fraud |
Penalty Framework
| Violation | Fine Range |
|---|---|
| Missing Limosa | €400 - €4,000 per worker |
| Check-In@Work failure | €400 - €4,000 per day |
| Wage underpayment (below PC 124 Cat III for posted masons) | €200 - €2,000 per worker |
| Fraudulent A1 certificate | Criminal prosecution + retroactive Belgian social security |
| Missing Construbadge | €100 - €1,000 |
Social Dumping Focus
Belgian inspectors specifically target posted masonry teams for:
- Paying below PC 124 minimums (using home-country wages instead)
- Fraudulent A1 certificates (posting entity with no genuine activity in home country)
- Category misclassification (Cat III masons paid as Cat I)
- Creating fake A1 forms is the #1 target of Belgian police in construction
Chain Liability
Article 30bis: main contractor jointly liable for subcontractor social debts. 35% withholding on invoices to non-compliant subs.

Total lead time: 4-6 weeks (posted) | 10-18 weeks (Single Permit)
12. Operational Warnings & Red Flags
Critical Warnings
- Social dumping enforcement: Masonry is the single most inspected trade for social dumping in Belgium. Posted masons paid below PC 124 Cat III (€20.62/hour) face immediate enforcement action against both the employer and the principal contractor.
- A1 fraud detection: Belgian authorities actively investigate the legitimacy of A1 certificates. If the posting entity has no genuine economic activity in the home country, the A1 is invalidated and full Belgian social security is assessed retroactively.
- Rain day compliance: Continuing masonry during rain or frost generates union complaints. Respect Weerverlet rules — the bad weather fund exists to compensate workers for lost hours.
- Flemish Bond competence: Belgian residential clients expect decorative brickwork as standard. Deploying masons without Flemish Bond experience results in quality rejection and commercial disputes.
- Renovation asbestos risk: Pre-2001 buildings may contain asbestos in mortar additives, insulation, or adjacent materials. Asbest Attest required before renovation begins.
Compliance Checklist

- Quarterly wage indexation applied
- VCA-Basis current
- Medical fitness certificate valid
- Weerverlet (rain day) procedures documented and understood
- Article 30bis social debt verification completed
- Flemish Bond competence verified (residential projects)
Trade-specific context
Respirable crystalline silica (RCS) dust is the dominant occupational exposure risk across all 29 jurisdictions. EU Carcinogens and Mutagens Directive 2017/2398 set a binding 0.1 mg/m³ 8-hour TWA limit, transposed nationally with stricter values in DE (TRGS 559: 0.05 mg/m³), NL (Arbobesluit 4.19: 0.075 mg/m³ [verify]), FR (Code du Travail R.4412-149), and IE (SI 622/2001 as amended). Wet-cutting and on-tool LEV (local exhaust ventilation, vacuum extraction with H/M-class filtration) are non-negotiable on EU sites since the 2019 Directive transposition deadline. CEN reference: EN 12779 (woodworking dust) is sometimes cited by analogy, but masonry-specific guidance falls under national authorities (HSE COSHH, BAuA TRGS 559 https://www.baua.de/, INRS ED 6451).
Manual handling: Brick and block weight thresholds are jurisdictionally set. DE Bauhauptgewerbe Tarif and BGV/DGUV guidance (DGUV Information 208-033) recommend single-handed lifting maximum 11 kg for repetitive masonry work; NL Arbobesluit 5.2 references 23-25 kg general but with task-specific NIOSH derating; FR Code du Travail R.4541 sets the framework with INRS practical guidance at 25 kg; IT D.Lgs 81/2008 Allegato XXXIII references EN 1005-2. Heavy aggregate-concrete blocks (>20 kg) must be two-person-lifted or mechanised (block clamps, mini-cranes).
Working at height: Scaffolding interface is governed by EN 12810 (façade scaffolds) and EN 12811 (working scaffolds — performance requirements). Mason-erected putlog and trestle scaffolds must comply with national equivalents — DE TRBS 2121, FR Décret 2004-924, NL Arbobesluit 7.34. PASMA-equivalent mobile-tower training (UK reference) maps to AGBau Fachkundige Person (DE) and SCC scaffold modules (NL/BE).
MSK injury from repetitive masonry motion is the largest long-term morbidity driver — knee bursitis, shoulder impingement, lumbar disc degeneration. Rotation between coursework and labouring tasks reduces incidence.
PPE baseline: EN 397 hard hat, EN 471/EN ISO 20471 hi-viz class 2, EN 388 cut-resistant gloves (level 2222 minimum), EN ISO 20345 S3 safety boots, EN 14404 knee pads, EN 149 FFP3 dust mask (mandatory for any cutting/grinding operation). Hearing protection EN 352 above 80 dB(A) when using cut-off saws.

Compliance Checklist
Belgium’s posted-worker regime applies the EU Posting of Workers Directive 96/71/EC and the Enforcement Directive 2014/67/EU as transposed by the Loi du 5 mars 2002 and consolidated in Title IV of the Loi-programme du 27 décembre 2006. Operational obligations:
-
LIMOSA notification. The Limosa-1 declaration must be filed via
https://www.limosa.beby the foreign employer (or the deployment partner acting on instruction) before the first day on Belgian territory. The declaration covers each worker individually and is renewable. A Limosa-1 reference number must be available on request to any Belgian inspector and to the Belgian client. Sanctions follow the Code pénal social: a level-4 administrative fine ranges EUR 2,400 to EUR 24,000 per worker for omission or non-renewal; criminal sanctions reach EUR 4,800 to EUR 48,000 with imprisonment of up to three years for severe or repeated breaches [verify scale]. -
A1 portable document. Mandatory for any worker remaining in their home-state social-security regime. Without a valid A1 covering the deployment dates, the Sociale Inspectie defaults the worker into Belgian ONSS / RSZ enrolment from day one, with retroactive contributions chargeable to the principal contractor under chain-liability.
-
Wage-parity (article 5, Loi du 5 mars 2002). The posted worker must receive the entire CCT remuneration of the relevant Belgian joint committee for the work performed. For construction this is CP 124 (Construction); for cleaning CP 121; for foodstuffs CP 220. Wage-parity covers base salary, vacation pay, end-of-year bonus equivalents and Constructiv-funded entitlements unless the home-state regime provides equivalent coverage.
-
Construction joint committees of relevance: CP 124 (Construction), CP 121 (Cleaning), CP 220 (Industries alimentaires). For EPC site logistics, transport workers fall under CP 140 (Transport et Logistique).
-
Designated representative. A Belgian-resident contact person (personne de liaison) must be nominated for each posting and recorded in the LIMOSA declaration. The representative receives all inspectorate correspondence.
-
Sanctions framework. The Code pénal social (Loi du 6 juin 2010) classifies infringements into four levels. Level 4, the highest, applies to wage-parity breaches, forced labour and chain-liability evasion. Multiplied per-worker, cumulative fines for a 30-worker unsubmitted LIMOSA can exceed EUR 700,000.
