The argument for this construction method is the sheathing height is decreased because the rim board is eliminated. However, in my mind the cons outweigh the pros:
1.) There is a thermal bridge through the stemwall at the corner where the floor meets the wall.
2.) Stemwall construction would become more complicated and time consuming.
3.) Proximity of the I-Joist to the concrete could be problematic, requiring additional measures and more time and effort.
4.) The crawspace height is reduced making it harder for other subs to install and work in and moisture from the ground is more likely to be an issue.
5.) Nut and Washer of anchor bolts protrudes into floor sheathing and bottom wall plate, requiring additional notching.
6.) If you want to run plumbing or electrical down through the wall bottom plate and into the floor, this is nearly impossible with this configuration.
