I had no idea on the cost until we went through an engineer. Happily surprised.

I guess where most people would encounter thousands of dollars is hiring the entire process out and working in a finished space. Putting it all back together when removing a finished wall can be costly. Luckily its just a concrete hole so far.

Option 1 is out for sure. Deciding between 2 and 3. Option 2 is attractive because it will be easy to relocate the electrical to the bottom of the joist neighboring the LVLs and have a small bulkhead to cover it up.
