3. OBSTACLES TO AEC PRODUCTIVITY
Fragmentation (unlike auto and aerospace)
The singular nature of construction projects
A lack of performance standards
Poor penetration of information technology
The workforce

5. OPPORTUNITIES TO IMPROVE PRODUCTIVITY
Consolidation
Prefabrication (Japanese modular construction)
Deployment of information technology

6. BIM OPPORTUNITIES It would make bidding truly competitive
It could facilitate prefabrication
It would force better collaboration among the stakeholders
It would require a more highly-trained workforce
It would improve efficiency in handling materials
It would improve the sustainability of building practice

8. PROBLEMS WITH BIM Interoperability Poor standards Size of models
Lifespan of buildings vs. software (Dassault)
