Background and European financing

The work culminates a process started in 2023, when ADIF Alta Velocidad tendered the consultancy and technical assistance to draft the acoustic protection project and the vibration study of the line, in announcement BOE-B-2023-5286 (file 3.22/30830.0271), with an estimated value of 1,596,800.40 euros and a duration of 30 months. That same year, the control of the works for complementary platform actions on the Murcia-Lorca section was also contracted (BOE-B-2023-39091, file 3.23/20830.0242).

The contract may be co-financed by the European Regional Development Fund (ERDF) for the 2021-2027 period and is covered by the Government Procurement Agreement.

The tender mobilizes more than 109 million euros on the Murcia-Lorca section of the Mediterranean corridor, where acoustic protections aim to reduce the sound impact of the new infrastructure on the municipalities it passes through. For construction companies, it opens a large-scale contract with specific classification in reinforced concrete and metallic structures; for residents, it marks the project’s transition to the execution of the works.
