Share & Discuss Fire Protection Drawings?

3/21/2022

This isn't really a question, but I wanted to see if anyone would be willing to share drawings they have done in the past with me?

I am looking to improve the look of our drawings, provide the AHJ with clear and concise information, and provide an all-around great end product. Thank you in advance!

If company information, logos, location, address, etc need to be removed or blocked in order to share the drawings, I understand.

Editor's note: We love this idea. If you're looking to share a sample (or set), email it to us at [email protected], and we'll update this post with images and links for discussion as they come in. Your images/drawings can be anonymous or credited, whichever you'd prefer. This could be a neat opportunity to discuss likes/improvement ideas.

Certainly. Is there a specific occupancy or hazard class you'd like to see?

I would like to see a variety myself, including tenant improvements.

Thank you!

I work as an AHJ so I thought I would add my input here as well. I will not conduct a plan review without the "Owners Certificate" (22.1.4* A signed copy of the owner's certificate and the working plan submittal shall include the manufacturer's installation instructions for any specially listed equipment, including descriptions, applications, and limitations for any sprinklers, devices, piping, or fittings.)

Once I confirm I have that I have a form and I ensure that the Working plans meet the criteria in 22.1.3. or if it is not applicable. After all that information is confirmed I start my review. Be sure look at the AHJ website and rules, I know for us the registration number for the contractor has to be on all correspondences including plans, submittals and hydraulic calculations.

22.1.3
Working plans shall be drawn to an indicated scale, on sheets of uniform size, with a plan of each floor, and shall show those items from the following list that pertain to the design of the system:
(1)Name of owner and occupant.

(2)Location, including street address.

(3)Point of compass.

(4)Full height cross section, or schematic diagram, including structural member information if required for clarity and including ceiling construction and method of protection for nonmetallic piping.

(5)Location of partitions.

(6)Location of fire walls.

(7)Occupancy class of each area or room.

(8)Location and size of concealed spaces, closets, attics, and bathrooms.

(9)Any small enclosures in which no sprinklers are to be installed.

(10)Size of city main in street and whether dead end or circulating; if dead end, direction and distance to nearest circulating main; and city main test results and system elevation relative to test hydrant (see A.23.1.8).

(11)Other sources of water supply, with pressure or elevation.

(12)Make, type, model, and nominal K-factor of sprinklers including sprinkler identification number.

(13)Temperature rating and location of high-temperature sprinklers.

(14)Total area protected by each system on each floor.

(15)Number of sprinklers on each riser per floor.

(16)Total number of sprinklers on each dry pipe system, preaction system, combined dry pipe–preaction system, or deluge system.

(17)Approximate capacity in gallons of each dry pipe system.

(18)Pipe type and schedule of wall thickness.

(19)Nominal pipe size and cutting lengths of pipe (or center-to-center dimensions). Where typical branch lines prevail, it shall be necessary to size only one typical line.

(20)Location and size of riser nipples.

(21)Type of fittings and joints and location of all welds and bends. The contractor shall specify on drawing any sections to be shop welded and the type of fittings or formations to be used.

(22)Type and locations of hangers, sleeves, braces, and methods of securing sprinklers when applicable.

(23)All control valves, check valves, drain pipes, and test connections.

(24)Make, type, model, and size of alarm or dry pipe valve.

(25)Make, type, model, and size of preaction or deluge valve.

(26)Kind and location of alarm bells.

(27)Size and location of standpipe risers, hose outlets, hand hose, monitor nozzles, and related equipment.

(28)Private fire service main sizes, lengths, locations, weights, materials, point of connection to city main; the sizes, types and locations of valves, valve indicators, regulators, meters, and valve pits; and the depth that the top of the pipe is laid below grade.

(29)Piping provisions for flushing.

(30)Where the equipment is to be installed as an addition to an existing system, enough of the existing system indicated on the plans to make all conditions clear.

(31)For hydraulically designed systems, the information on the hydraulic data nameplate.

(32)A graphic representation of the scale used on all plans.

(33)Name and address of contractor.

(34)Hydraulic reference points shown on the plan that correspond with comparable reference points on the hydraulic calculation sheets.

(35)The minimum rate of water application (density or flow or discharge pressure), the design area of water application, in-rack sprinkler demand, and the water required for hose streams both inside and outside.

(36)The total quantity of water and the pressure required noted at a common reference point for each system.

(37)Relative elevations of sprinklers, junction points, and supply or reference points.

(38)If room design method is used, all unprotected wall openings throughout the floor protected.

(39)Calculation of loads for sizing and details of sway bracing.

(40)The setting for pressure-reducing valves.

(41)Information about backflow preventers (manufacturer, size, type).

(42)Information about antifreeze solution used (type and amount).

(43)Size and location of hydrants, showing size and number of outlets and if outlets are to be equipped with independent gate valves. Whether hose houses and equipment are to be provided, and by whom, shall be indicated. Static and res

Start with the title block. It's your brand, it makes a drawing appear official and important. It's an expression of you, your department, your company and over time helps build your brand.

The title block gives the AHJ, the GC, Field Crews, etc., critical information about the document, including the project name, author, date of issue, topic, its place within a drawing series, etc.

It gives all of the project’s documents a consistent, professional look and when shared across your team, gives the overall organization a consistent look.

Consistency matters.

"Every good drawing deserves a great title block"

I doubt I will share any of my own drawings, but I have always told my design trainees to imagine receiving your drawing, and a load of pipe and fittings, at a poorly-lit, rainy, noisy jobsite. Can you hit the ground running, sorting the pipe, know where to begin installation? Think like a fitter. Are your pipes elevated and dimensioned off real-life things, not some imaginary grid-line or the middle of a wall? Do your pipes and sprinklers stand out boldly compared to the background lines? And you really don't need to show chairs and tables on the background, but show lighting and HVAC grilles, and structure. Include real, job-specific hanger and bracing details. Develop a designer's checklist. As mentioned above, use the Working Plans section of NFPA #13. Have a fellow designer or supervisor put another set of eyes on the drawing before it goes out, otherwise their stamp means nothing. The drawings get you your permit, but are your primary means of communication to the fitter, and can make or break the job. I usually print a set for the fitter that is different from the submittal drawing, different things turned on and off. Listen to feedback from fitters. All off the top of my head, just for starters.

Dave, I believe the question concerned the submittal to the AHJ. However, you are absolutely correct about the field prints...the field doesn't need all of the information the AHJ needs. I was taught to dimension off of elements that don't move (i.e., Columns) invariably walls move due to revisions ect. Back to the AHJ point of view, and from a designers perspective, I never used to show door swings until an AHJ wanted me to due to the travel distance and path for fire hose lines. I also now show parking spaces in garage designs for the same reason, but never used to. I also show the toilet's and bathtubs because it aids in referencing where the bathrooms are. This is especially handy in residential building designs. Additionally, sometimes it takes less time to just leave things the way they are then to erase the architectural features. I will however explode them and place them in a layer that will plot faintly.

You are correct Wally, I totally overlooked the AHJ-part; thanks. I kinda got off on a tangent; you make good points.

3/21/2022 05:50:54 pm

For AHJ use, I try to clearly indicate things like water supply and source of that info, design criteria, type of structure, cross section, and I clearly cite NFPA sections that I may be utlizing, such as increases or reductions, decision path for storage commodities, and exceptions I am taking advantage of. For T.I.'s I make clear what is existing, new, and "relocated" and what walls/ceiling are existing vs. new. Room names, hazard classification. State pipe and fittings types. Remote areas clearly shown. Personally, I always state a "Scope of Work" and start point. Similar to the installation drawing, does it quickly and clearly communicate what I am trying to convey, the AHJ may or may not have yet seen the architectural and structural. The more information I can provide to the AHJ the better my design is usually received, and the more trust that is built.

I think it might be useful to have a small public database of drawings. I couldn't think of a better site to host it on than meyer.
