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...
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.
We are installing a fire sprinkler system in a warehouse...
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.
I'm designing a system that is Ordinary Hazard Group II...
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...

I'm using AutoCAD 2008 and I'm having a problem when using paperspace. I have a drawing that has been very jumpy. By jumpy I mean, in model space when I zoom in and out, it jumps. It's hard to explain. But, when trying to select grips or snap points, it's difficult to maneuver the mouse...
Ok, I wanted to get a thread going on this topic. This thread is about 2 things: 1)Determination of whether you have to seismically brace and 2)Seismic bracing in 13R systems. I have done a decent amount of research on this subject but please correct me if I'm wrong on any of this.

I'm currently working on a hops warehouse (0.30 gpm/ft^2 and 2600 ft^2) and actually will be doing 3 more in the next few months. My question involves the hanging method for the line piping. The current hops warehouse is existing construction and has insulation panels (celotox or other brand)...
I just did a pump test for a large cherry processing facility and during the test thought to myself, "there has to be a better way to do this". I am referring to controlling the flow of water out the test header. I used 2 1-3/4 inch stream straighteners and 2 fire hoses attached to 2-1/2 inch...
I'm working on a sprinkler system for a 3 story hotel and each unit contains an "enclosed space" to contain a unit that is used to cool the room. I use the quotes to designate the emphasis of this post. These units are stand alone and have no connecting ductwork to any other units. The hotel...
Yes, I received a drawing from an architect that had many xrefs. I want to copy the drawing and paste it into my own template with my own layers, but to do this I have to bind his xrefs to the drawing to make them actual layers. I was successful in binding all but 1 of them. It gives me an...
