MLIT Information Technology Policies
MLIT Innovation General Framework, May 2007 Utilize the next-generation CAD so that we can improve
quality controls throughout building lifecycle.
Computer aided Acquisition and Logistic Support
(CALS/EC) Action Program 2008, March 2009 Utilize BIM through all building stages

BIM Pilot Projects in MLIT/GBD since 2010
Challenges
1. What kind of information do we need?
2. What kind of hardware should we adopt?
3. Designer’s Copyright
4. Information Delivery from Designers to
Contractors in Design-Bid-Build methods
