Tender for Light Rail Track Rehabilitation at Braunschweiger Verkehr GmbH

Tender Reference Number: 124860-2026 (Official Journal of the EU Number)

Project Title: Track Rehabilitation Works in the Area of the Schloss Light Rail Station (Gleisinstandsetzung im Bereich der Stadtbahnhaltestelle Schloss)

Contract Type: Works

CPV Code: 45234116 (Railway construction works)

Lot Number: LOT-0001 Track and Civil Engineering Works (Gleis-und Tiefbauarbeiten)

Project Location: Schloss Station, Braunschweig, Germany (Haltestelle Schloss)

Project Scope:

Existing Track Removal: Dismantle 120 meters of existing standard track, including rails, fastenings, sleepers, and associated ballast materials, with compliant disposal.

Existing Turnout Removal: Dismantle 110 meters of existing turnout track, including the complete turnout assembly and ancillary structures, ensuring the site is left clean.

Grooved Rail Turnout Installation: Install 110 meters of new grooved rail turnout, using Rillenschiene (grooved rail) conforming to German light rail standards, suitable for shared urban right-of-way.

Grooved Rail Crossing Installation: Install 40 meters of new grooved rail crossing, ensuring geometric precision and load-bearing capacity in the crossing area meet operational requirements.

Standard Rail Installation: Install 80 meters of new 60R1/60R2 type standard rails, applicable for transition zones or non-embedded track areas.

Grouting Mortar Supply and Application: Supply and produce on-site 16,000 kg of grouting mortar for track embedding, ballast filling, and structural fixing.

Concrete Strip Pavement Installation: Install 14 cm thick concrete strip pavement over a 550 m² track area, requiring a level, anti-slip, wear-resistant surface meeting conditions for shared urban road/track use.

Steel Fiber Reinforced Concrete Canopy Pouring: Pour 20 cubic meters of steel fiber reinforced concrete canopy (grey) for station areas or underpass structures, enhancing crack resistance and durability.

Traffic Safety Measures Implementation: Responsible for traffic safety management throughout the track and civil engineering construction period, including warning signs, temporary barriers, and pedestrian/vehicle guidance measures to ensure public and construction safety.

Material Environmental Compliance: All dismantled materials must be sorted, recycled, or disposed of according to German environmental regulations; random dumping or landfilling is prohibited.

Construction Precision Control: Track installation must meet German light rail operational standards (e.g., BOStrab), including requirements for gauge, level, superelevation, and geometric alignment precision.

Interface Compatibility with Existing System: Newly installed tracks and turnouts must achieve seamless integration with the existing light rail system, ensuring compatibility with signaling, power supply, and operation.

Operational Guarantee During Construction: Construction in certain sections must coordinate with light rail operational windows to minimize impact on public transport services.

Quality Assurance and Acceptance: The construction process is subject to inspection by the client or a third-party supervisor. Upon completion, submit as-built documentation, material conformity certificates, and test reports.

Warranty Period Requirement: A warranty period commences after final project acceptance. The contractor is responsible for repairing material defects and construction quality issues.
