| Abstrait: |
As part of the project management of the Auvergne rail restoration plan carried out by the Société d’études techniques et économiques (SETEC) on behalf of the French Rail Network (SNCFR, Société Nationale des Chemins de Fer Réseau), Diadès was responsible for the diagnosis evaluation of four wrought-iron nineteenth-century viaducts located on the Lavaufranche–Saint-Germain des Fossés line. Once the viaducts’ archived documents had been analysed, a complete diagnostic and investigative programme was carried out, including taking dimensional measurements and samples, conducting detailed inspections, anti-corrosion diagnosis, spectrocolorimetry analysis of the gathered data and recalculation of the fatigue of the structures. These results were then used to create a procedure for the restoration and painting of two viaducts while addressing the problem of the presence of lead in the original paintwork. The works were carried out on the Rouzat Viaduct by Lassarat, managed by Diadès. |
