Am I right in thinking that one should edit 21 13 00.00 40 for the piping
leading into the fire riser room and delete the references to the sprinkler
system (and any other unused interior piping) and specify the sprinkler system
from the riser into the occupied space(s) using 21 13 13?

I’ve been asked to look at a new industrial building, generally unoccupied
except for servicing, that has a fire and gas detection system and audible and
visual notification devices.
At this point I’m not sure this facility actually requires a FA system, as it
might just be an owner
We do a fair amount of design at an Air National Guard base that has a HP fire
line to service various hangers and the associated AFFF systems. This system
was installed before my time, but it does have a few hydrants on the system, I
think mainly for flow testing as the system expands. I will

Many times there is a topping slab that can cover a through bolt and backing

I like to spec embedments in parking ramp decks for the mains as it is such a

We have a community college client that wants to replace standard ACT with a
perforated metal mesh tile that is 60% open. My assumption is that change would
require installation of heads above the ceiling in the area of the metal mesh,
perhaps putting a bulkhead around the area with the mesh
