is this a open web floor truss system or possibly done after the fact.
From here in GA, those look like engineered wood i-joists with manufactured cut-outs to run ductwork or other components. Not open web.
Did you see anything that resembles this?

No I did not. I did see what appeared to be 1/4 in plywood sistered to the side of some of the holes. This set up ran the entire joist on everyone I could see. half of the basement was finished. I will say the cuts did not look fresh and the 1/4inch wood on the side of the joist appeared original.

Do you have any other photos? As best I can tell, the joists are an older version of the modern-day i-joist.

no unfortunately the rest of basement was finished
im thinking noting the notches, stating that on the day of the inspection on the sections I could see the joists appeared to be performing as designed. Let the client know if they want to ensure future performance have it looked at by a contractor.
My guess is a DYI type of joist. The plywood does not appear to have straight cuts, which it would if factory-built.

Built on-site does not equal DYI, in my opinion.

No, but the quality of the cut may indicate non-pro work (maybe). My guess is if it were engineered there would be a specified overlap and fastening pattern. But all just a wag.
Agreed. Both may be satisfied. (mostly
