This is a scenario that I have crossed numerous times in my building career and will try to explain as best I can. Remember I am French and sometimes confuse more than I explain. ha. ha.
I my area, design Architects of out of State or in-State will come up with designs that show the brick bearing on top of the foundation with the counterflashings under the brick.
I will always change that design with a sketch showing why it is wrong.
I will show them that creating an 8" brick shelf in the foundation and dropping the counterflashing below the finished floor, will always prove better for water and moisture intrusion into the finshed floor. Weep holes in this case would be 8" below finish floor.
In the other scenario, the brick shelf is situated below grade and some of the bricks get buried and not showing concrete foundation above grade.
In this design, the buried 8" +’/- bricks are slushed with grout in the cavity and the counterflashing is installed one brick below finished floor with weep holes every two feet above grade. Weep holes come in a variety of design such as corrugated plastic butt joint inserts, PVC tubing and the old cloth weeps rope.
The eight inches of buried brick will be backed up with grout, and my extra preventive assurance, I also install weeps underground for release of whatever moisture that could get trapped behind the brick at the underground portion. This is an option and not really required by Architectural Designs.
The key here is to provide proper weeps of the cavity and have the counter flashings installed below finished floor so there is no chance of water seeping or wicking under the sill plates.
Hope you follow all this without pictures.
Posting pictures is not my bag. Still illiterate I guess. ha. ha.
