ABSTRACT
All tunnel projects, with their unique engineering challenges, demand effective information modelling and management. Nowadays, Building Information Modeling (BIM) is a standard technology, yet during implementation project parties are confronted with ambiguities in reference documentation. Clients, contractors, designers and other stakeholders - all seek to maximize information inclusion in BIM Models. However, determining the right balance between necessary and excessive information remains elusive. It’s not just about technology; it’s about people, processes, and potential. Engineers, architects, and construction professionals comes together, speak the same language, and work towards the same goal to create safer, more efficient, and sustainable tunnels. This paper delves into the application of BIM Approach within a tunnel project, based on the “BIM in Tunneling. Guideline for Bored and Conventional Tunnels” developed by the International Tunnelling Association (ITA) Working Group 22 (WG22): Information Modelling in Tunnelling. We present strategies for information exchange, supporting geotechnical and structural analysis. Beyond design and construction, tunnel projects have long lifecycles. Integrating BIM with lifecycle assessment tools allows us to calculate essential data. By supplementing asset objects with analysis results, we enhance the information density of the BIM Model.
