An older warehouse about 30 years old equipped with wet K=8.0 SR uprights on a system designed for baled cotton storage having a density of 0.25 gpm over 3000 sq ft with 500 hose.
I believe it is just fine just as it is and even though it is a light hazard occupancy not having QR sprinklers...
I have a cold storage warehouse with a double interlocked preaction system where I plan to use a water storage tank and fire pump. Pump will be rated at 1,500 or2,000 gpm.
Flow test results of the city watermain show 68 psi static, 42 psi residual @ 993 gpm. 20 psi @1,400 gpm.
500gpm hose...
First off it is NEVER my call to decide whether a system is to be designed per NFPA #13 OR 13R.
That call is 100% the call of the project registered architect of record and nobody else.
So I am looking at a two story project where there three offices with a residential area designed per NFPA...
I have an older 200,000 sq ft warehouse which used standard response K=8.0 uprights and today they want to store plastic products.
FM Global wants Data Sheet 8-9 Table 10 and with the building height 35'-0" it appears we have a choice between 12 K22.4 @ 75 psi or 12 K25.2 @ 60 psi.
Yes, we are...
I can't find anything in FM Global data sheets that addresses the addition of sprinklers to the ductwork but even if I did I would want something from FM Global but...
I have done the insides of a roasters and kilns but never the ductwork.
I am just curious if anyone has run into this?

It's a 12,000 sq ft welding shop and the owner thought he could save some money by installing it himself.
No drawings, no calculations just 100% CPVC pipe and pendent sprinklers used for upright and sidewalls.
No tamper, flow switches, inspectors test, aux. drains and no need for a main drain...
I have a concealed space made up of 2"x8" solid wood joists @ 16" oc.
We have approximately 2'-0" between the bottom of the solid wood joist and 2x4 accoustical ceiling.
I am planning to use sch. 10 steel pipe with Viking VK950 COIN sprinklers spaced a maximum of 14'-0" Deflectors would be 1...
Question about FM Global Data Sheet 8-9 Table 8 "Ceiling-Level Protection Guidelines for Class 4 and Cartoned Unexpanded Plastic Commodities in Open-Frame Rack Storage Arrangements"
I have a 156,000 sq ft warehouse and when we started out the owner told me to design per NFPA #13 for rack storge...
I have a 200'x200' building with a single slope roof having a 1/2" in 12" pitch.
Low side is 32'-8" to underside of deck.
High side is 41'-0" to underside of deck.
I need to use K22.4 pendant ESFR sprinklers @40 psi which covers us for Cartoned Nonexpanded plastics.
Problem I have is we...
What we see here is just part of a 10,000 sq ft floor space and what we see in the photo below is the finished product. Even the offices you see on the top photo has the exposed wood joists.
Construction was completed two years ago so what you see is what you get as an end product.
If we...
I have a job where I am using K25.2 pendent ESFR heads where the building is rigid metal frames and 8" bent metal purlins.
The 2 1/2" branch lines will be as high as possible next to the bottom of the purlins so the deflector is a maximum of 18" from the roof deck or ceiling.
14.2.10.1.3...
I'm pretty sure I am correct in my approach but I would like any input.
If the 8" loop was part of the city watermain I would not have to add any domestic water allowance as the domestic water would be fed from the 8" city main and not from the main feeding the fire sprinkler riser.
However...

In 45 years I have yet to have a project where I would have to have a ground storage tank because where I am, south Georgia swamp land, I've always gone with a vertical turbine pump out of a pond. Travis, where I am if you did a hole it will fill with water.
I have a storage facility that...
An existing 60 plus year old building that used to be a hotel but is now being converted to monthly rental apartments.
Per the architect and local building officials the building needs to be equipped with sprinklers installed per 2019 Edition of NFPA #13R.
With the exception of only the...
From the photos it appears the entire building was lost... all 250,000 sq ft.
I am most interested in the design of the sprinkler system.

Not your usual NFPA question but it does have something to do with fire sprinklers and NFPA standards.
I know we have a number of insurance company people here and I would like to have an idea fire sprinklers have on insurance rates especially for storage facilities and Extra Hazard production...
I have a 196,000 sq ft warehouse that has a street frontage of approximately 700'.
Not that it really matters but the warehouse will store exposed Group A plastics and I am looking at an ESFR system using pendent K16.8 heads. Pretty standard.
I am going to need six systems with a fire pump...
I just got these drawings this afternoon and until now I have never run into this one before.
I have a four story apartment building where the four floor level exceeds 30' above fire department access so a standpipe is required.
Thing is I have never run into a building that required...
In 45 years I've never used one but if I understand what they are correctly then this could be my first time.
Storage building exceeds 500,000 sq ft so it isn't a small project.
ESFR system using K16.8 heads discharging at 52 psi so the total amount of water I need, with hose streams, is 1,710...
