The core scope of work for this tender is the preparation of executive project documentation (IZN) for the rehabilitation of steel and massive bridges. The tender is divided into five lots, each focusing on the creation of IZN for specific bridge structures, including their anti-corrosion protection (AKZ) and rehabilitation.

The specific projects under this tender include:

• Lot 1: Preparation of IZN for the rehabilitation and AKZ of the Steel Bridge at km 1+875 on railway line no. 72 Prvačina – Ajdovščina.
• Lot 2: Preparation of IZN for the rehabilitation and AKZ of the Steel Bridge at km 101+911 on railway line no. 70 Jesenice – Nova Gorica – Sežana.
• Lot 3: Preparation of IZN for the rehabilitation and AKZ of the Steel Bridge at km 44+396 on railway line no. 70 Jesenice – Nova Gorica – Sežana.
• Lot 4: Preparation of IZN for the rehabilitation of the Otovec Viaduct at km 49+127 on railway line no. 80 d.m. – Metlika – Ljubljana.
• Lot 5: Preparation of IZN for the rehabilitation of the bridge over Grubarjev prekop at km 151+232 on railway line no. 80 d.m. – Metlika – Ljubljana.

The high-level summary of the Statement of Work (SOW) for the individual bridge rehabilitations typically involves:

• Repair of the massive part of the structure, including strengthening stone blocks, rehabilitating bearing beams, cleaning and jointing gaps between stones, and repairing damaged concrete.
• Replacement of worn-out walking plates with new galvanized, grated roofing.
• Repair of corroded and damaged steel structure elements and complete anti-corrosion protection of the steel bridge, including the fence.
• Detailed processing and workshop plans for the replacement of any worn steel parts, if necessary.
• Cleaning and lubrication of steel movable bearings.
• Designer supervision throughout the works.

Core deliverables include:

• A precise bill of quantities and a designer's estimate for the executive project, along with workshop plans if required.
• For structures involving watercourses, a status report that includes an inspection of bridge supports in the watercourse by divers.
• An implementation plan for the rehabilitation of river supports, including technological plans and static calculations.
• A technological elaboration of the execution.
• Acquisition of all necessary approvals, opinions, and permits from relevant authorities like the Water Directorate and ARSO.
• The static plan, as part of the project documentation (PZI), must be a standalone plan adhering to current legislation, technical regulations, and Eurocode standards with national annexes. It must detail the technical description, existing condition, damage assessment, inspection results, static calculations for both existing and proposed rehabilitation states, load determination, stability verification, dimensioning of new or reinforced elements, and detailed structural plans.
• The final project documentation (IZN) for each lot must be submitted in four printed copies and on one unencrypted USB stick. The electronic documentation must be provided in both passive (PDF) and active/source (Word and DWG) formats, ensuring consistency with the printed versions.

The overall project, across all lots, is required to be completed by November 30, 2026.
