Conclusion

© 2016, Dr. Ling Ma 

  • Information is the core of building information model
  • CRUD is the common use case of information collaboration
  • Semantic enrichment is an important process for BIM adoption

Machine learning for more complex cases

Tested on synthetic cases

Conditions of the Highway Bridges

One in nine of the bridges in the US are structurally deficient

FHWA needs $20.5 billion annually to eliminate the bridge deficient backlog by 2028, but $12.8 billion is being spent

607,380 National Bridges in the US !!!

Over two billion trips are taken daily across these bridges
