- The underwater inspection and bathymetry were the subject of a very detailed prior planning in order to take into account the large size of the elements to be observed (> 4,000 m2) and various constraints, such as the high speed flow, high tidal range, poor visibility and significant marine traffic. In the underwater inspection, the pier facing was cleaned in horizontal and vertical bands, forming a representative observation grid.
- Underwater inspection documented using photograph, video and an explanatory anomaly diagram to check the state of conservation of the submerged area of the structural work infrastructure or the area in contact with the waterline (concrete area). Bathymetry. Comparative analysis of the previous situation with the current one. Preparation of reports regarding the works that were carried out, with recording, illustration and schematisation of the anomalies or damages detected.
