but would branch lines need to be braced as well? the potential swaying motion
in a move i would think would be greater than motion due to earthquakes

If these are modular homes its likely cpvc that isn't going anywhere.

If done to West Coast seismic requirements the branch lines would be
restrained, the ends having a secondary, lateral brace (rod with an end
line loop hanger or the rod run down to the pipe, at an angle to restrain
lateral movement). Our stuff moves in all directions with the building
movement, no
The sprinkler system was installed on-site, after the building was set-up.

An account is moving a pre-fab building. The occupancy is classrooms and
office space. They want us to disconnect and connect the sprinkler piping in
the attic. But, as I am considering this, I keep coming up with more concerns.
Some of which, in not particular order, are:
1. They will
All good ideas, and per 25 if the inspection that should be done with the
system down and disconnected suggests back-flushing is a good idea then
there would be your authority. If you don't do underground then you need an
underground guy. If I recall properly, you're in NE Oregon up by The Dalles
In addition to those, my concern would be that if the pipe is suspended from
the structure, it will probably sway back and forth during the move and could
possibly damage heads or pipe.

They put the sprinklers in off site for manufactured buildings all the time, is
this that different? All the other trades get installed before shipping as
well. I was doing some work for a company a whole back that built all the
building in there factory and they had sprinklers installed
Whether or not the system would sway during moving would be dependent on
how it's currently installed. If in earthquake country it wouldn't sway
since it would be braced against seismic events. Pre-fabs are designed to
be moved so swaying is minimized by sway bracing or hung in such a way as
to
