During 𝐄𝐂𝟑 – 𝐂𝐨𝐦𝐩𝐮𝐭𝐢𝐧𝐠 𝐢𝐧 𝐂𝐨𝐧𝐬𝐭𝐫𝐮𝐜𝐭𝐢𝐨𝐧 𝟐𝟎𝟐𝟔, held in 𝐂𝐨𝐫𝐟𝐮, 𝐆𝐫𝐞𝐞𝐜𝐞 from 𝐉𝐮𝐥𝐲 𝟏𝟐 𝐭𝐨 𝟏𝟓, I had the pleasure of presenting our work: “𝐒𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐚𝐥 𝐇𝐞𝐚𝐥𝐭𝐡 𝐌𝐨𝐧𝐢𝐭𝐨𝐫𝐢𝐧𝐠 𝐨𝐟 𝐁𝐫𝐢𝐝𝐠𝐞𝐬: 𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐧𝐠 𝐎𝐩𝐞𝐧𝐁𝐈𝐌, 𝐆𝐈𝐒, 𝐚𝐧𝐝 𝐈𝐨𝐓 𝐢𝐧 𝐭𝐡𝐞 𝐁𝐫𝐞𝐠𝐚𝐧𝐳𝐞 𝐁𝐫𝐢𝐝𝐠𝐞 𝐂𝐚𝐬𝐞 𝐒𝐭𝐮𝐝𝐲.” We developed a web platform that integrates the validated 𝐎𝐩𝐞𝐧𝐁𝐈𝐌 𝐦𝐨𝐝𝐞𝐥 of the bridge with a 𝐆𝐈𝐒 𝐞𝐧𝐯𝐢𝐫𝐨𝐧𝐦𝐞𝐧𝐭 (𝐌𝐚𝐩𝐋𝐢𝐛𝐫𝐞) enabling users to understand the spatial context and seamlessly switch to a 3D view to interact with the bridge model and visualize sensor measurements. Key contributions of our work include: • 𝐈𝐃𝐒 𝐛𝐚𝐬𝐞𝐝 𝐦𝐨𝐝𝐞𝐥 𝐯𝐚𝐥𝐢𝐝𝐚𝐭𝐢𝐨𝐧: To ensure accurate metadata representation (sensor specifications, material properties, naming conventions, etc.). • 𝐒𝐞𝐦𝐚𝐧𝐭𝐢𝐜 𝐧𝐞𝐬𝐭𝐢𝐧𝐠 𝐨𝐟 𝐬𝐞𝐧𝐬𝐨𝐫𝐬 𝐚𝐧𝐝 𝐡𝐨𝐬𝐭 𝐞𝐥𝐞𝐦𝐞𝐧𝐭𝐬: Sensors and host are spatially adjacent but semantically disconnected are linked under 𝙄𝙛𝙘𝙀𝙡𝙚𝙢𝙚𝙣𝙩𝘼𝙨𝙨𝙚𝙢𝙗𝙡𝙮. • 𝐔𝐩𝐝𝐚𝐭𝐞𝐬 𝐨𝐟 𝐈𝐟𝐜𝐒𝐞𝐧𝐬𝐨𝐫 𝐢𝐧𝐬𝐭𝐚𝐧𝐜𝐞: Sensors are enriched with significant values (latest, max, min) and corresponding timestamps. • 𝐈𝐧𝐭𝐞𝐫𝐚𝐜𝐭𝐢𝐯𝐞 𝐬𝐞𝐧𝐬𝐨𝐫 𝐞𝐱𝐩𝐥𝐨𝐫𝐚𝐭𝐢𝐨𝐧: Double‑clicking a sensor or its host element automatically plots the associated measurements. • 𝐀 𝐜𝐨𝐦𝐩𝐥𝐞𝐭𝐞 𝐥𝐢𝐬𝐭 𝐨𝐟 𝐚𝐬𝐬𝐞𝐦𝐛𝐥𝐢𝐞𝐬: Effortless identification of structural hosts, automatic 3D localization, and visualization of all related sensor plots. • 𝐓𝐡𝐫𝐞𝐬𝐡𝐨𝐥𝐝 𝐛𝐚𝐬𝐞𝐝 𝐯𝐢𝐬𝐮𝐚𝐥 𝐚𝐥𝐞𝐫𝐭𝐬: 3D color‑coded visualization of host elements with sensors measurements below or above defined thresholds. A big thank you to my supervisors (Francesca da Porto, Carlo Zanchetta, Giovanni Tecchio), colleagues(Giorgia Marcellino, Andrea Gennaro), and ITS Engineering Company BIM Team(@Guido Asciore, Mattia Berto, Ilaria Terramagra) for making this work possible. #EC3 #EC32026 #ComputingInConstruction #StructuralHealthMonitoring #BridgeMonitoring #BIM #OpenBIM #BIMInteroperability #BIMGIS #MapLibre #IoT #IFC #IFCOpenShell #IFCJS
