01. Pre-pricing — Convention Collective PC 124 BTP + IG Metall-equivalent split
Hyperscale-DC mobilisation prices each posted worker against Convention Collective PC 124 BTP for the civil-shell portion, with N1P1 floor €1,843 gross/month (2026 grid). Energised-cabinet electricians sit under NF C 18-510/A2 habilitation framework (June 2023 amendment) at BR / BC / H1V / H2V depending on scope. CIBTP Congés contribution 20.70% national (Sud-Ouest 20.20% from 1 April 2026); Intempéries 0.68% gros œuvre / 0.13% second œuvre for the 81st campaign (1 April 2026 – 31 March 2027).
Constructys legal training contribution 1% in 2026 (includes CCCA-BTP 0.30% Building / 0.22% Public Works).
02. SIPSI déclaration + A1 + URSSAF attestation
Every posted worker arrives with a Portable Document A1 and the SIPSI déclaration submitted pre-departure (mandatory since 1 October 2016). The URSSAF attestation de vigilance is 6-month validity, required at every contract conclusion ≥€5,000 HT and every 6 months thereafter. SIPSI per-worker fine ceiling: €4,000, €8,000 repeat offences.
Carte BTP per-worker fine ceiling: €4,000 per employee, €8,000 repeat, capped at €500,000 per company under Article L.8291-2 Code du travail.
03. CIBTP + Constructys onboarding
The Caisse de Congés Intempéries BTP enrols the construction-trade portion before site presence. Constructys handles the apprenticeship + training contribution. Where MEP scope predominates and the Convention Collective de la Métallurgie applies instead, the receiving Niederlassung pivots.
04. URSSAF + DREETS-defensible evidence pack
Décret 2025-1338 (26 December 2025) entered into force on 1 January 2026, applying social-contribution control and recovery against the contractor chain. The URSSAF solidarité-financière cascade has a 5-year retroactive horizon. Minimum survivable pack: SEPA-traceable remuneration on a French bank account, French-language employer-of-record contract, SIPSI déclaration record, Carte BTP per worker, A1 portable doc, NF C 18-510/A2 habilitation record per energised-work individual.
05. India and Gulf sourcing corridors — the FR hyperscale pathway
The Indian and Gulf corridors deliver pre-cleared cooling, controls, and energised-cabinet trades. The FR recognition pathway runs through Reconnaissance des Qualifications Professionnelles (EU 2005/36/EC transposition). The NF C 18-510/A2 habilitation is issued by the French employer-of-record after site-specific examination by an organisme certificateur.
The 8 to 14-week corridor lead-time delivers the French-eligible candidate against Equinix PA10, Microsoft MRS Marseille or the Azure France Central cluster.
