Earthwork to Asset,
One Workforce Pipeline.
Civil-Engineering Prime Cohort — Distinct from Hochbau
The buyer landscape is Tiefbau / Travaux Publics / VRD — civil-execution rather than building-execution. Named primes: Ludwig Pfeiffer Hoch- und Tiefbau, Wayss & Freytag Ingenieurbau, Implenia Bau, Strabag AG (Tiefbau division), Eiffage Génie Civil et Métallique, Bouygues TP Régions France, Colas Centre-Ouest, NCC AB (SE), Peab Anläggning (SE), Veidekke Anlegg (NO/SE), Sisk Civil Engineering (IE), Coffey Construction (IE), Jacobs Civil. Procurement posture is per-Strecke / per-Los across Strassenbau-Verwaltungen and Wasserstraßen-Neubauamt; per-département for FR Travaux Publics.
VOB/C ATV DIN 18299 ff. — Per-Trade Execution Baseline
VOB/C ATV DIN 18299 (Allgemeine Regelungen) sits over the Civil-Engineering ATV stack: DIN 18300 Erdarbeiten, DIN 18301 Bohrarbeiten, DIN 18305 Wasserhaltungsarbeiten, DIN 18313 Schlitzwandarbeiten, DIN 18316 Bituminöser Asphalt, DIN 18320 Landschaftsbauarbeiten. Per-trade execution norms govern workforce qualification — VOB-conform deployment requires the worker's competence proven against the specific ATV, not against a generic Bauhauptgewerbe baseline. SOKA-BAU at 20.2% Bruttolohn West applies; Mindestlohn-Bau LG1 (currently €13.50/h, lifted 1 April 2026 to LG2/LG3 step) is the wage floor.
Eurocode 7 Geotechnical + Eurocode 2 Concrete Execution
EC7 (EN 1997-1 + EN 1997-2 geotechnical design) governs the design-side; the execution-side draws on EN 1536 (Bohrpfähle), EN 1538 (Schlitzwände), EN 12063 (Spundwände), EN 14199 (Mikropfähle). EC2 / EN 1992 + EN 13670 (Ausführung Tragwerken aus Beton) cover concrete execution; CE-marking for precast concrete per EN 13369 + product standards. Workforce qualifications attach at the named execution standard, not at the trade card.
VRD + Strassenbau + Bridge-Erection Specialisation
VRD (Voirie et Réseaux Divers) — French linear-infrastructure assembly — runs through CACES R482 (engins de chantier), R483 (camions toupie), R486 (PEMP), R489 (chariots), with NF P 98-150 ff. (chaussées) anchoring the road-execution norms. Bridge-erection draws on EN 1993-2 (steel bridge), EN 1992-2 (concrete bridge), EN 1090 EXC3/EXC4 for the steelwork superstructure. Demolition and reconstruction of legacy structures runs through SS3/SS4 amiante in France; Bergbau-Folge-Sanierung VA-BKS VI in DE Braunkohle-Folgeflächen.
Cross-Border Mobilisation — VOB vs CCAG-Travaux vs AB04
Each jurisdiction's public-civil contracting regime governs different obligations: VOB/B (DE) vs CCAG-Travaux (FR) vs AB 04 / ABT 06 (SE) vs PSF Travaux Publics (Luxembourg) vs The Public Works Contracts (IE). The contracts differ on Nachträge / réclamations, defects-liability, retention. Workforce qualifications must align to the contracting regime — a worker qualified against VOB execution standards does not automatically meet FR CCAG-Travaux documentation. Pre-mobilisation cert-match is per-contracting-regime, not per-trade.
Civil-Engineering vs Hochbau (Buildings) Workforce Regime
The civil-execution regime layers VOB/C ATV per-trade norms + EC7 + EC2 + CACES heavy-plant + sectoral CBA wage. Hochbau screening does not transfer to Tiefbau.
| Conventional Agency | Bayswater | |
|---|---|---|
| Execution standard | VOB/C ATV DIN 18330 (Mauerarbeiten) — building-side | VOB/C ATV DIN 18299 ff. (Civil-side stack) — DIN 18300 Erdarbeiten / DIN 18301 Bohrarbeiten / DIN 18313 Schlitzwand / DIN 18316 Asphalt / DIN 18305 Wasserhaltung |
| Design baseline | EC1 (loads) + EC5 (timber) + national TR for buildings | EC7 (geotechnical) + EC2 / EN 13670 (concrete execution) + EC3 / EN 1993-2 (steel bridge) — execution-side norms govern workforce qualification per ATV |
| Wage Tarif | Bauhauptgewerbe Mindestlohn-Bau LG2/LG3 step 1 April 2026 | Same Mindestlohn-Bau scaffold + AVE-Bezug verified per execution standard + SOKA-BAU 20.2% Bruttolohn West |

| Cross-border contract | Posted-worker A1 + sectoral CBA | VOB/B (DE) vs CCAG-Travaux (FR) vs AB 04 (SE) vs PSF Travaux Publics (LU) — workforce docs align to contracting regime, not to a generic posted-worker baseline |
