AQ6222 – Digital infrastructure for engineering structures, as well as design services for structural monitoring systems for bridges, viaducts and tunnels

The Anas AQ 6222 Framework Agreement aims to digitise national infrastructure works using BIM methodology. Cooprogetti, as contractor together with RTP, managed Lot 4 (Lazio 49 works, Campania 54, Sardinia: Cagliari 121, Sassari 127) as part of the Anas Structural Health Monitoring (SHM) programme, aimed at developing the Digital Twin of the works.
The work began with the acquisition of historical data, survey data and point clouds, which form the basis for digital modelling in accordance with UNI-11337, UNI EN ISO 19650 and the Anas BIM Information Specifications. The modelling takes into account LOG (Level of Geometry) and LOIN (Level of Information Need), defining geometric detail and information associated with the elements.
Information parameterisation uses Parametric Clusters, particularly for LOD C, including 6D information such as the “BMS Code” to identify elements during inspections. The LOR (Level of Reliability) indicates the reliability of objects with values ranging from very low to high, associated with specific RGB colours. Thanks to the coordination of the RTP, Cooprogetti has adopted a flexible and automated workflow, improving productivity and compliance with Anas requirements. The growing use of BIM represents a step towards the integration of traditional engineering and technological innovation for Cooprogetti.
