Igor,
Nice floor joists. What the heck was he thinking?
What did it look like on the other side? Did these joists continue?
And what was all over the elbows on the copper piping? GUM

I really don’t see a problem here. Looks like good practice to me. Those sarn framers always put those joists in the way.

Looks like something a tinknocker friend of mine who does HVAC installs would do … his favorite tool is a sawsall
I thank him every time I see him for generating work for me ... I think he is finally getting the hints
BTW ... current code only allows notches 1/6 the joist height deep x 1/3 the joist height wide ... and no notches at all in the middle third of the span. Plus bored holes can only be 1/3 the joist height in diameter with 2" clear top & bottom. Pretty limited, eh.

Just cut it the HE** out, you did not need that joist anyway! 
BTW...you can cut it the whole way through, assuming it is supported! But you knew that didn't you!

Robert,
Are you saying that you can not cut the whole way through a TJI joist and only Dave is correct?

Joe … not sure what you mean by “cut the whole way through” for a TJI, but I will give ya the basics.
IRC R502.8 does not permit any cutting, drilling, or notching of a TJI (or any other engineered wood or trusses) unless specifically permitted by the manufacturer.
For TJI's the top or bottom chord/lumber may not be cut, drilled or notched at all. It's like a small truss with the top/bottom lumber as the chords ... you would never cut/notch those. The plywood/particleboard web may be cut/drilled to a diameter almost the depth of the web ... as long a the hole is at least 2-diameters clear to another hole and 1-diameter clear to the end (rule of thumb ... see APA guide for actual distances). See page 15 of the APA guide at the following link:
http://www.apawood.org/pdfs/managed/EWSZ725B.pdf
Another thing that is often missed is the "squash blocks" at TJI supports if there is a bearing wall above. The ends of a TJI tend to crush, particularly if it gets wet. See this link.
http://www.apawood.org/pdfs/managed/A755.pdf
Hope that helps.

Robert,
Thank you for that truly informative post. Now what do you think happens when the joists shipped to the jobsite are too long? Do they send them back for replacements or does the contractor cut them to fit?
I have to warn you, this is not a trick question!

Okay Joe … yes, wood I-Joists may be trimmed to fit on-site if they are ordered too long. That is the big advantage of I-Joists over open web wood joists which can not be trimmed to fit.
There is a fairly newer product which is an open web joist that has solid webs at the ends to allow field trimming ( http://www.trimjoist.com ) which is generally for longer floor or flat roof spans.
But once a standard I-Joist is installed the top/bottom flange (Igor is right) may not be cut, drilled, or notched.
