MANAGING PUBLIC INFRASTRUCTURES THROUGH BIM MODELING RAILWAY TUNNELS FOR INFRAESTRUTURAS DE PORTUGAL
Main Article Content
Abstract
The Architecture, Engineering and Construction (AEC) industry requires strategies to digitalize the built environment. These strategies need to facilitate the development of as-is models from existing repositories and databases, making the management of this information more efficient throughout the asset’s life cycle. One methodology frequently applied in AEC is Building Information Modeling (BIM), which allows the creation of digital replicas of the built environment. To test the advantages of BIM in the management of railway infrastructures, a BIM-based plugin was developed to facilitate the visualization and manipulation of a repository containing BIM models of several railway tunnels. The article elaborates on the methodology adopted in the development of the plugin, as well as the management process it supports. The advantages of centralizing various types of data in a shared 3D model are also discussed, not only in terms of communication and data sharing between various stakeholders, but also regarding decision-making processes and the planning of inspection/intervention activities throughout the assets’ life cycle.
