The Port Authority of Las Palmas has approved the report justifying the need and suitability for the restoration work on the iconic Arinaga Lighthouse, located on the coast of the Gran Canaria municipality of Agüimes. The structure, responsible for providing essential maritime signaling and navigational guidance services on the eastern coast of the island, is suffering from advanced deterioration caused by its continuous exposure to a highly aggressive marine environment.
The project has a base bid price excluding taxes and an identical estimated value of €47.304,23. The infrastructure, crucial for maritime signaling and navigational safety on the island's eastern coast, is suffering significant wear and tear due to its constant exposure to a highly aggressive marine environment.
The combination of constant humidity, direct impact of salt spray, prevailing winds, and intense solar radiation has severely damaged both the concrete cladding of the shaft and the metal components exposed to the elements.
To restore the architectural complex to its optimal condition of durability and operational safety, the technical project includes a range of specialized work. Among the planned tasks is the installation of a complex tubular scaffolding structure that will envelop the entire vertical length of the tower. This will allow workers to meticulously chip away and clean the damaged surfaces, removing the material affected by internal corrosion. Subsequently, high-performance technical mortars will be applied for structural repair, new surface leveling coatings will be applied, and a complete repainting process will be carried out using salt-resistant systems. Simultaneously, all the railings and metal elements of the upper lantern will be repaired and protected.
From an administrative perspective, the procedure is directly supported by the Consolidated Text of the State Ports and Merchant Marine Law (TRLPEMM), which grants port authorities exclusive jurisdiction over the maintenance and operation of service and signaling works. Furthermore, the file explicitly justifies not dividing the contract into lots. Port technicians warn that the different work units—from scaffolding assembly to protective finishes—are inextricably linked in an unbreakable chronological sequence, and therefore, fragmenting the execution among multiple contractors would jeopardize technical coordination and the success of the work on this tower in southeastern Gran Canaria.
