Integrated framework improves asset management and reduces query times in national road bridge inventories, suggesting benefits for infrastructure efficiency.
Key Points
To design and validate an integrated framework for asset management of national road bridge inventories.
Developed a BIM-GIS framework for lifecycle asset management.
Established a data exchange architecture between BIM models and GIS databases.
Created a data schema mapping structural attributes to geospatial objects.
Derived algorithms for condition index computation and deterioration prediction using Markov chains.
Achieved a 62% reduction in query response time for 10,000+ bridge records.
Projected net present value savings of about USD 2.4 million per 100 km of highway over 50 years.
