APPLICATION · SPEZIALTIEFBAU

Specialty Foundations.
Foreurs to Soudeurs.

Bauer / Liebherr / Casagrande multi-axis rig operators, EN 1090 EXC3/EXC4 ferrailleurs, EN ISO 9606-1 soudeurs for têtes de pieux — the specialty roster Grand Paris Express, LGV, nuclear and offshore-adjacent lots demand.

Cadrer la Mobilisation Spezialtiefbau

An owner-managed Spezialtiefbau or fondations spéciales prime competes with Soletanche-Bachy, Bauer, Implenia, Keller and Menard on a workforce profile the BTP labour pool cannot supply organically.

The pinch points are not generic ferrailleurs. They are 18-to-36-month-certified foreurs on Bauer BG, Liebherr LB and Casagrande multi-axis rigs. EN 1090 EXC3 / EXC4 ferraillage with full traceability. EN ISO 9606-1 welders for tête de pieu lots. Décret 2025-1338 URSSAF cascade exposure is maximal — specialty lots run 2-3 tiers below SGP, SNCF Réseau, EDF and nuclear principals.

Full applicability Conditional / scope-dependent Not applicable

CACES (France), Patentino (Italy), Maschinistenausweis (DE / AT) and BCCA (BE) rig-operator certifications are not directly portable between jurisdictions — destination Anerkennung pathway documented at sourcing.

01/

Rig-operator certification and Anerkennung pre-processed

18-to-36-month rig certification (Bauer BG, Liebherr LB, Casagrande) verified at sourcing; destination CACES / Patentino / Maschinistenausweis Anerkennung initiated in source country, not at arrival.

02/

EN 1090 EXC3/EXC4 ferrailleur chain

Cages de ferraillage and execution-class traceability documented per crew. Contrôle technique (Bureau Veritas, Apave, SOCOTEC in FR; ITC / TÜV in DE) receives a defensible trail, not a contested lot.

03/

Décret 2025-1338 URSSAF discharge for specialty sub-tiers

Specialty Fondations lots typically sit 2-3 tiers below the SGP, SNCF Réseau or EDF principal. Per-worker discharge documentation pack assembled before mobilisation closes the cascade exposure at the cell, not at the chain.

04/

Indian / Gulf welder pool for tête de pieu work

Tier-1 Indian welding-institution graduates with documented Gulf project experience; EN ISO 9606-1 cross-walked into the receiving notified-body register before deployment.

Specialty foundations workforce at LGV scale

Twelve-minute Technical Briefing on rig-operator, ferrailleur and soudeur sourcing against the specific Spezialtiefbau lot.
