I'm working on an 1880's masonry four story historic building that currently has no fire sprinkler system. We're looking to retrofit a fire sprinkler system and we're looking into any and all ideas for concealing the pipe but keeping the historic charm.
This building itself has concrete beams with 'tin' ceilings in-between. We're considering building down false beams, furring out entire walls, and potentially soffits to help conceal pipe. For those who have complete sprinkler retrofit designs for historic buildings, what tips or methods have you used to make your projects successful? Posted anonymously by a member for discussion.

Have you considered concealing pipe in crown moldings and protecting with HSWs? I know that they make a residential product that is made to do just that. Of course, you did not provide particulars of your installation. Is it non-combustible/obstructed? What is the occupancy classification?

Hopefully, there's a basement or a lower level where you could run the main(s) and branches. On a 4-story state capital restoration, we could not lower the ceilings, but we could cut in the stone walls. It was barrel vault construction and we had an 1-1/2" available to run the branch lines. The sq. footage was small enough that we could consider the whole building as a single zone. We ran the branch lines vertically and offset horizontally for each room. Worked well.

I’m considering a similar retrofit for a homeowner with a basement and plaster and lath walls. Did each first floor sidewall sprinkler have its own 6-7 foot dead end riser? What type riser pipe and diameter was approved? Were vertical pipe anchors at the floor and sprinkler sufficient or did you have to open the wall in between as well? Thanks very much for any feedback. Fortunately it’s much easier on the second floor going in from the attic. Leave a Reply. |
