ADIF tenders overhead contact line works for Teruel–Sagunto rail electrification

ADIF gives an estimated value of €51,538,518.31 and a 24-month duration for the works. The published record does not provide a start date, so the term is reported as duration only.

Spain’s rail infrastructure administrator ADIF has opened a tender for overhead contact-line works on the Teruel–Sagunto section of the Zaragoza–Teruel–Sagunto railway. The notice defines the contract as execution of the construction project for electrification of that segment, specifically the overhead contact line. It is a works contract with a stated duration of 24 months. The estimated procurement value is €51,538,518.31, and submissions are due on 27 November 2026 at 13:00 (+01:00).

The notice locates the project across the autonomous communities of Valencia and Aragón. It does not provide a kilometre count, mast or foundation quantities, wire configuration, traction-power interface, commissioning plan or detailed work schedule. Nor does the short published scope state whether the project contains associated substations, feeder systems or other electrification assets beyond the named contact-line works. The tender should therefore be understood narrowly as the construction of the overhead contact line identified by ADIF, while the technical documents will determine the full boundary and engineering requirements.

The award framework divides evaluation between criteria assessed through qualitative judgment and criteria quantified by formula. The notice assigns 49 points to the judgment-based criteria and 51 to formula-based criteria. It does not name those criteria in the concise description returned here. The split makes the evaluation nearly even between technical/qualitative assessment and formula-scored components, but it does not support a conclusion that either price or quality alone determines the result. Bidders need to consult the tender rules for the component criteria and evidence requirements.

For contractors, the two-year duration and published estimated value frame a significant railway systems construction package, although the notice’s scope field is limited to the contact line. Delivery planning will depend on access to the active railway, work possessions, interfaces with existing systems and the engineering design issued by ADIF. Those operational constraints are not detailed in the notice summary, so this report does not assert planned closures, service impacts, construction techniques or energisation milestones.

The published event is an invitation to tender, not an award or a report that work has begun. ADIF lists the internal reference as 3.26/27507.0275. The procurement notice identifies Spain as the country of performance and gives its deadline in local offset notation. Interested firms should verify the full technical and commercial documents through the official procurement channel before relying on quantities, interface scope or evaluation subcriteria beyond those stated in the notice.

ADIF’s internal procurement reference is 3.26/27507.0275, and the notice states that tenders remain valid for two months. The contract has a 24-month duration, but no start date is published. Its estimated value is €51,538,518.31, not an awarded sum. The notice confines its project description to the overhead contact line; site access, existing-system interfaces and work possessions must be resolved through the technical dossier rather than assumed from the route name.
