AQ 6222 – Survey, BIM modelling and design services for structural monitoring of bridges, viaducts and tunnels under Framework Agreement

The Anas Framework Agreement AQ 6222 aims at the provision of surveying services and the creation of the BIM model, aimed at the digital infrastructure of works of art, as well as the design services of structural monitoring systems for bridges, viaducts and tunnels, under a Framework Agreement. Lot 4, for which Cooprogetti is responsible, covers the regions of Lazio, Campania and Sardinia for a total of 127 works. The project, part of the Anas programme ‘Structural Health Monitoring (SHM),’ develops the Digital Twin of the monitored structures, starting with the acquisition of historical documents and survey data for digital modelling, following the UNI-11337 and UNI EN ISO 19650 standards and the Anas BIM Information Specifications. BIM modelling considers the level of geometric (LOG) and information (LOIN) detail, including parameters such as the ‘BMS Code’ for inspections and the ‘Level of Reliability’ (LOR) to assess the accuracy of objects. Thanks to the automation and flexibility of the workflow, Cooprogetti improved productivity and compliance with Anas requirements, confirming the importance of the BIM methodology for the qualitative evolution of engineering.
