1	During the process, all ongoing CBMDM tasks can be tracked and managed easily and effectively through the CBMDM system. I think that the CBMDM system will be more convenient and helpful than the email system.
2	The CBMDM system let me obtain related CBMDM tasks effectively. It helps me a lot to handle the problems and responses to the CBMDM issues.
3	I used email to manage all CBMDM tasks. Now, I prefer to check and manage the newest status of responses to the CBMDM task quickly and effectively.
4	The CBMDM system can record all historic communication information regarding the issues of CBMDM tasks. It is very useful and helpful for me to find and refer to the necessary information based on selected issues. This proposed CBMDM system is different from existing BIM software.
5	One of the biggest advantages I felt was that the CBMDM system stores the records of communication regarding the components of the BIM models, which was very helpful for me to find and refer to the necessary information during the process.
6	Although there are many limitations of CBMDM tasks in practice, the development of the CBMDM system is to meet the practical requirements of CBMDM tasks.
7	I can respond to all the current ongoing issues related to CBMDM tasks and access all the unfinished CBMDM results effectively through the CBMDM system.
8	The CBMDM system allowed me to communicate with engineers about selected components of the BIM model and discuss problems, that was very effective for us during the CBMDM process.
