There isn’t really any type of “regular” floor in wood, but the 3 most common are dimensional lumber (2x10s for example), engineered joists (TJIs which are dimensional top and bottom chord and OSB web) and engineered trusses (what you see here, dimensional chords and webs.
I apologize for that typo, it’s TGI I-Joists, explained above briefly. The incorrect penetrations can happen in either dimensional joists or engineered joists. The easy rule of thumb is no more than 1/3 the diameter of the material (9” joist being 3” max) and has to be in the inner 1/3 (9” again so no holes within 3” of the top or bottom of the joist.
Now most engineered joists come with pre penetrations and any deviation without their express consent can void their warranty, BUT following general guidelines shouldn’t lead to any issues.
