Yeah an engineer is most definitely my best choice right now. The flooring was built for future construction I just didn't think about where the walls will sit. Depending on what the engineer says I have 2 options.
1. Land the new walls on a load bearing point.
2. Tie the ceilingceiling joists into the roof rafters.
#1 when likely change the room dimensions which I don't want to do.
#2 will add a lot of money to the project.
