Summary

DB InfraGO AG is procuring construction work to renew a railway bridge crossing (Kreuzungsbauwerk) located on the electrified line 3505 near Wiesbaden-Biebrich, Germany at km 44.020. The project involves replacing the existing crossing structure with a single-track steel lattice bridge (100m span), raising track elevation by approximately 1.70m, reinforcing an adjacent heritage-protected arch bridge with a concrete cap structure, constructing a new track bed plate with deep foundations, installing sheet pile walls with anchoring, and building prefabricated angle support walls to protect cable trays. The work requires contractors to hold German railway prequalification (PQ-VOB) or equivalent certification and comply with extensive eligibility and compliance requirements including sanctions screening, professional registration, and ethical conduct standards.
