Structural
That looks strangely like many buildings I have seen around the world. - In those the concrete frame is built just before the (or with) the masonry infill.
Hamza41: The in-fill units are adequate for the loads they see. The actual strength of the CMUs would be in the range of 3000 psi to 8500 psi depending on what the manufacturer decides. - The cheapest way to increase the strength is to add water, but the appearance may be less desirable. The cost of the cement is less than penalty (decreased production rate) incurred by adding water. - 6" thick CMUs seem to be the most common for multi-story buildings like apartments since the individual panels are not over 8' high.

Concretemasonry:
I’m doing a slight thread highjack here...,
Dick, would you please look at the thread titled “CMU Disintegrating,” thread507-435859, 23FEB18, and tell us what you think on the subject. I would be interested to hear what you have to say, have you seen this before, what causes it, etc. All conc. blks. don’t seem to be affected the same way, all the time, even though in the same location, and while 5,6,7 blks. are severely deteriorated.

Thank you.
In fact this drawing has been provided by a client as guide drawing.
I wouldn't put masonry below grade.
We are used to clay brick masonry which is not reinforced and used only as infill walls with limited heights due to their poor resistance.
