At the start in Tusa, in the Messina area, the consolidation of the rocky ridge on which the Castle of San Giorgio stands out. The structure for the contrast of the hydrogeological instability, led by the president of the Sicilian Region Renato Schifani, gives news. The offices directed by Sergio Tumminello have made official the successful tenderer of the contract: to carry out the works, by virtue of a drop of 33.1 percent and for an amount of 655 thousand euros, will be the Antonino Chillè srl of Saponara (ME).
The work consists in the stabilization of the area on which the San Giorgio fortress develops, with the consolidation of the East and West side. The goal is to eliminate the hydrogeological risk on a side overlooking the sea of Castel di Tusa and in which, starting from 2009, numerous collapses of portions of rock have occurred. A situation that forced the municipal administration to run for cover, closing that stretch of beach.
Among the technical solutions contemplated by the project, the cleaning of the shrubs on the two sides and the consolidation of the rocky wall. We will then proceed with the detachment of the boulders in precarious balance and with the demolition of those of high size. Lastly, a double twisting metal network will be placed with hexagonal shirts and network panels, not before having sealed the crepes of the ridge with cement mixture in order to avoid the infiltrations of rainwater.
Also awarded the safety works of the inhabited center of Gallodoro
The structure to combat the hydrogeological instability, led by the President of the Sicilian Region Renato Schifani, also won Gallodoro, in the Messina area, the safety works of the Landro district. The consolidation intervention, based on the ranking drawn up by the offices directed by Sergio Tumminello, will be carried out by a temporary grouping of companies coordinated by the DLM Costruzioni Srl of Barcellona Pozzo di Gotto (ME), due to a reduction of 32.4 percent and for an amount of 773 thousand euros.
The surface landslide movements in the town of Gallodoro, located on the Peloritani mountains, north of Taormina and inside the area between the Alcantara river and the Fiumara d’Agrò, are very widespread. Landshirts that have occurred in recent years and which have made the north-eastern side dominated by a rocky wall and with a very high risk classification (R4) particularly vulnerable and unstable. From 2009 onwards the different episodes of falling boulders have caused important damage to private buildings and a series of infrastructures as well as the underground network.
The project includes regaining interventions, the disregard of unstable blocks and the location of paramaxes and barriers. The main problem is that of the speed of the waters that descend by gravity and this is why they make it necessary to drain and conveying. We will then proceed to the location of a barrier paramassi downstream of the area, already stabilized with cortical network.
