It's hard to keep the rough-in
of gas pipes, plumbing, electrical, and mechanical runs from becoming a free-for-all - with subs vying for stud and joist spaces.
The additional beams have been added, carrying the second floor, and the second-floor joists that have to be "sistered" have started the rough-ins
at the building.
Potential installation problems are limited with lavatory systems because the units are mounted directly to the wall with up to 70-percent fewer plumbing connections and rough-ins
. Pre-assembled lavatory systems install in about half the time of a row of individual sinks.
(The hurricane clips were embedded in the concrete on lay-out.) Framers also use steel studs to frame inside along the exterior concrete walls; that creates a cavity for rough-ins
and insulation and an attachment for drywall.
