I'm hoping someone has run into this issue and can provide some guidance on how to proceed. A brand new fire marshal that has taken over a major county in which we work is steadfastly enforcing NFPA 170 - Standard for Fire Safety and Emergency Symbols. Specifically, Chapter 7 that addresses...
Stookeyfype, this project is in the United States. It is designed under the 2015 IFC and as the 2013 Edition of NFPA 400 is the recognized Reference Standard in Chapter 80 of the IFC, it also applies. I'm curious to hear your elaboration.
The situation I'm dealing with is a unique one. I'm not sure it's specifically my responsibility to address this issue, but I'm involved. It's in a remote location. I'm hoping someone reading this has had some experience with this.

My belief is that their request of 4,000 gpm @ 20 psi (my example) is more along the lines of a steadily held water network like a municipality provides. A city or county has multiple pumps throughout their jurisdiction(s) that maintain specific static pressures based on usage (people taking...
As we all know, fire departments/jurisdictions use a specific gallonage requirement (i.e. 4,000gpm in my example) @ 20 psi as their requisite fire flow. How do I size a fire pump @ 20 psi? In my experience, pump curves don't go that low. I don't do a lot of pumps, maybe 1-2 a year, but most...
We design many automatic fire sprinkler systems under the design criterias of FM Global in our area. Mostly, storage applications. Recently, our local AHJ has raised concerns about accepting FM Global Design Criteria from a legal standpoint. NFPA 13 is an accepted standard by the...
I have a building (cold storage facility)that I'm providing fire protection to that is constructed of 38" deep Red L web trusses. Plywood is attached to the bottom of those trusses. This creates a combustible concealed space 38" deep. 12" of R38 insulation rests on the plywood. I am installing a...

I'm trying to develop a cookie cutter criteria for dictating when to change the sprinkler head k-factor. Maybe, it's not possible to have a fixed plan for this, but I thought I'd throw this out to the community to see what you think.

Excellent suggestions. Thank you. I'm checking out Hilti's website and looking at the PD 40. I think that's the next sibling in the PD line to your PD 30 TravisMack.

For survey work, we've been using a Spectra Precision Handheld Laser Model HD 150 and it just died. Doing some research for a new handheld laser measuring device and curious what people these days use out there.
I know Leica is a good brand, but not looking to spend thousands of dollars...
I wanted to share a recent experience I had and get commentary. In the past few months I worked on an NFPA 13R project for a 7-building 3-story each apartment complex. Each unit had a bathroom that was less than 55 ft^2, and thus, according to the 2007 edition of NFPA 13R, not required to be...

Thanks Chicopee. Yes, I always open the original drawing and "bind" any existing xrefs to that drawing, then clean it up the way I want it to look before I plot to .dwf, then xref it into my drawing. Could you further explain the "nesting" of multiple xrefs into a drawing? Do you mean, don't...
