When you're framing the floor, check the blueprints to see where any such openings might go, and header off any joists that might be in the way in advance.

https://www.jlconline.com/how-to/framing/field-guide-to-comm... ver foto,,dice...Interrupted joists must be** headed off**to transfer their loads to adjacent joists. If the header spans more than 4 feet, it must be doubled and the loads transferred to double trimmer joists.
Framing Openings Cut in Floors
A common problem occurs with floors when subs cut through joists to make room for plumbing runs, hvac ductwork,(ducts, vertical chase british words?) or other mechanical elements. The loads these cut joists supported must be properly transferred to other joists. You can do this using header joists, end nailed across the cut ends of the interrupted joists, to carry loads to the adjacent trimmer joists. Where the** header **has to span a space less than 4 feet wide, a single header end-nailed to the trimmer joists will do.

Things get more complicated if the header must span more than 4 feet. If that’s the case, both header and trimmer joists should be doubled. The doubled trimmer joists must be nailed together properly (with spaced pairs of 16-penny nails every 16 inches) so that they act as beams. The header joists must be appropriately anchored to the trimmers. End nails will do for **header spans **up to 6 feet; beyond that, use hangers. Any tail joists over 12 feet should also be hangered.

When you’re framing the floor, check the blueprints to see where any such openings might go, and header off any joists that might be in the way in advance. It’s much easier than trying to work from underneath the subfloor later.
