CONCLUSION

Conclusion Conclusion

Contribution

Lesson learned

Contribution • Design a flood safe renovation of an existing building • Scheduling a construction • A rough cost estimation

Lesson Learned Common views • Different background makes some difficulties, but we think on the same line to finish the project.

• Hard to participate because of being in the virtual team.

• Work responsibility is not clear.

Different views • UW: lack of specific information about the project and knowledge • IIT: understand the India English problems and thank Will for his help • IIT: 7:00 AM is too early • IIT: hardware and Internet problems are challenges but it is getting better
