Stuttgart 21, Albvorland, Brenner Basistunnel — DB Sicherungsanweisungen on every OLE bond.

DB Netz runs Germany’s electrified-rail infrastructure under EBA approval, with Konzernrichtlinie 132 (Sicherungsanweisungen) governing OLE work. Stuttgart 21, Albvorland and Albabstiegstunnel are the Wendlingen-Ulm NBS section; Brenner Basistunnel sits at the DE-IT border under joint BBT SE delivery.

01. Pre-pricing — BG-ETEM + DB Sicherungsaufsicht authorisation

OLE crews sit under BG-ETEM with AVE-Elektrohandwerk (€14.93/h) as the wage anchor. The DB Sicherungsaufsicht qualification — separate from BG-ETEM membership — authorises the worker to operate within the cleared work zone for a specific Sicherungsanweisung. Sicherungsaufsicht is per-Netzbezirk and non-portable: a worker authorised in DB Netz Süd may need re-issue when transferring to DB Netz Ost.

Civil shell (tunnel cross-section, station boxes, tunnel-lining segments) sits under SOKA-BAU 20.2% with Mindestlohn-Bau LG3 €23.97/h from 1 April 2026.

02. Meldeportal-Mindestlohn + A1 + DB Sicherungsaufsicht file

Every posted worker arrives with A1 + German-language contract + Meldeportal-Mindestlohn filing. The DB layer adds the Sicherungsaufsicht-Prüfung + EFK qualification (DIN VDE 1000-10 / DIN VDE 0115-1) per worker. The pre-cleared status is verified against the Sicherungsanweisung at the Netzbezirk gate before track access.

Per-worker fine ceiling under §23 AEntG reaches €30,000. The Sicherungsaufsicht is the operational gate — a worker without it does not cross into the work zone.

03. SOKA-BAU + BG-ETEM onboarding

Tunnel and rail-electrification build splits across construction (civil shell, segmental lining, station box) under SOKA-BAU + BG-Bau, and electrical commissioning (OLE, signalling power, traction substations) under BG-ETEM. The Baustellenausweis carries the determining classification per individual. Dual-membership is administratively normal.

04. SchwarzArbMoDiG-defensible evidence pack

Since 1 January 2026, the Finanzkontrolle Schwarzarbeit’s rail-OLE inspection profile uses biometric on-site identity capture, live payroll-IT access, and automated cross-matching against A1 / DRV / Meldeportal-Mindestlohn / the DB Sicherungsaufsicht register. Minimum survivable pack: SEPA-traceable remuneration, ArbZG timesheets archived continuously, retrievable German-language contract, EFK + Sicherungsaufsicht trail, BG-ETEM membership confirmation, and Anerkennung-recognition documentation.

05. India and Gulf sourcing corridors — the rail-electrification pathway

The Indian rail-trade pool delivers IIW-certified OLE-fitters and BHEL-trained traction-substation commissioners (BHEL has built and maintains a significant fraction of India’s electrified-rail network). The Gulf corridor is less active for rail. Anerkennung in Deutschland for the EFK qualification is scoped per worker before deployment; the DB Sicherungsaufsicht-Prüfung is scheduled into the 2-4 week post-arrival window.

The 8 to 14-week corridor lead-time delivers the EFK-qualified pool against DB Netz Süd, Ost or West protocol before site clearance.
