Water based systems layout Level III
Water based systems layout Level III
(OP)
So, the time has come, at last. I have signed up for Firetech's courses, and am about halfway through the General Plans Portion of it. Still need to start the Hydraulics course. Both my General Plans & Hydraulics NICET Test are paid for, and just need scheduled. Anybody have any tips? Pointers? Suggestions?
Everything I have read on here about the Hydraulics test has me concerned. And how is the General Plans portion? Everybody I talk to in person gives me the same response: "I took the test when it was Work Elements, don't know anything about the Computer Based stuff."
Anything anybody wants to add to the conversation would be greatly appreciated!

RE: Water based systems layout Level III
I have recently taken and passed NICET 3, Layout of Water-Based Systems in the CBT format, and unsuccessfully attempted NICET 3, Hydraulics. I have also participated in Firetechs course for Layout, though not hydraulics.
As far as Firetech is concerned, from what I've seen (and I've been researching for two years), they offer the most comprehensive training. My only criticism is that it's too comprehensive. They cover EVERYTHING. It's information overload, so the additional challenge of sifting through the pile and picking out what's relevant presents itself. Don't get me wrong, there's immense value in their product, and what I'm saying is only my opinion, but the greatest investment you could make is to simply buy the books and read them. Read them every single night, chapter by chapter, write down questions that come to mind as you read, and find answers by reaching out to the community. Build a mental rolodex of the anatomy of each book, and be able to recall by memory the number and title of each chapter. Observe and follow the content outlines provided by NICET on their website. Above all else, respect the content of each book. By that, I mean don't assume that anything in any book is less important than the rest. It's all of equal importance, and requires your time and attention.
Purchase the Firetech tabs because they're awesome, and comply with NICET's requirements regarding tabs.
Other people have passed these exams, so logically they are passable. To me, this means that success is inevitable if you're willing to settle in for the long haul, and make sacrifices. DO NOT GIVE UP.

Did you have to learn hand calcs when you started out as a design trainee? My first boss made me learn to calc by hand. I had to do trees and simple loops. We laid off the compound loops and grids. That laid a great foundation for understanding how to do the calculations for NICET. Now, I did take it many years ago. I passed III and IV hydraulics on the first try, if I recall correctly.
Maybe Firetech just teaches the old hand method. The SFPE handbook has a section on loop calcs that really helps. They talk about an FLC (friction loss coefficient) in the loops that gets you equivalent lengths and such to have your loops calc very easy.

RE: Water based systems layout Level III
I learned how to do some hand calcing using the AFSA courses when I first started out. Also, a PE friend of mine lent me his college textbooks to study from, and I have played around with them. But at work, I use HydraCALC. After I get through the general plans test next week, I intend to fully immerse myself in hand calcs for a bit, and see how it goes. My thought was to try some, and compare what I come up with to what HydraCALC comes up with. I also have my PE friend lined up for a "study session" after I have a couple weeks in, so if I hit something I am having trouble with, he can help me through it. Also, I am signed up for Firetech's course, but again, I was going to start it once I get passed the first test. I am in a unique situation where I work, where as when our designer quit, I was handed the position, and had to self learn a lot on the fly. AFSA was a huge help, as was the gentleman I replaced, but it was a lot to absorb all at once! Luckily, I spent a decade in the field as an installer, so I already had a pretty good understanding of sprinkler systems in general.

I'm not sure if loop calcs are required for Level 3 but pretty certain they are for Level 4.
There are lots of opportunities to make very easy mistakes in hydraulic calculations.

RE: Water based systems layout Level III
O is the orifice, i.e. what PSI do i need to push out the required amount of water. Solved for with the Q=K *(sqrtP) or with end head pressure like 100 psi for a Class I standpipe, 7 psi minimum for a sprinkler, CMSA sprinklers' listing, etc.
U is up or elevation losses. 0.4331 psi/ft of elevation added or subtracted if the piping goes down.
T is through or as above the friction losses through devices, pipe, fittings; anything the water flows through. This is found in the equivalent length tables of NFPA 13, product data submittals for valves or backflow preventers, pipe specs, etc.

RE: Water based systems layout Level III
It is a bummer to be sure but most of us here failed at least once down the path to our certification so you are not alone. I took my first test back in the 1980's, failed miserably and I thought I was very well prepared.
I know you can't remember the exact questions and answers but can you give me a couple examples of the obscure questions?
RE: Water based systems layout Level III
I'm not sure if it is too late, but can you challenge any of the questions. I recall one of my questions was in reference to minimum spacing from a truss web member. I was applying the 3x rule as that was the required referenced standard. However, none of the answers were even close to the 3x rule. They were based on a standard 2 editions prior. I think I found the exact answer in a standard from the 80's or late 90's. That was definitely not the referenced standard. I believe that challenge may have saved me on one of the elements.
If you have a legit reason for proving the question(s) referencing the incorrect standards, would that be enough to pass??

RE: Water based systems layout Level III
When taking my exams I took some grey-hairs out to lunch to quiz them about old ways of doing things. The exams I took covered buried fabric bag water storage tanks, wooden cooling towers and weird stuff like that which I had never seen. Some of that stuff ended up on the exams and it wasn't that any of us are stupid but sometimes there are just odd questions on the exams.
We are here to help, if you can think of any general things you might need to study we can probably help. If you PM me i should have some study material I can pass on. I'm looking to take my NICET 4 next year.
RE: Water based systems layout Level III
I re-read my post from a week or so back, and realize that I was referring to the General Plans Preperation (aka 3A exam) as, "Layout of Water-Based Systems." Apologies, as I meant General Plans, or 3A...
DO NOT LET YOUR FAILURE DISCOURAGE YOU. It took me three tries before I passed, and it took a village to make it happen. Many people answered what now seem like ridiculous questions, including Travis Mack in this forum, which made all the difference. Anyway, I spoke with a guy in Salt Lake City that recently passed Hydraulics (aka 3B), and it took him five tries. This is what I was referring to at the end of my first post, when I said that success is inevitable if you're willing to settle in for the long haul, and make sacrifices. One more piece of advice - don't stop studying or take a break to let the dust settle. You know what they're going to throw at you now, and you've got 90 days until you can test again. Study every day.
Best of luck, I hope you pass.

RE: Water based systems layout Level III
Sprinklerdesigner2, the two questions I am stuck on are:
1. The plans call for a 90 to be bolted right to a city main, with the OS&Y valve bolted directly to the 90. What pump allows this layout?
A. Split case horizontal Electric
B. Split case horizontal Diesel
C. Vertical Turbine
D. Vertical Inline
I haven't found this answer yet. My fire pump supplier is UPS'ing me a couple of books, along with the NFPA20 Handbook. I am curious to see if it is in there, as I can't seem to find it in NFPA20.
2. A lobby has a ceiling that is 24' high. There is a ceiling pocket that is a 25' diameter circle in the center, that is 26' high. There are 8 standard heads space evenly around the perimetere of the pocket. Per NFPA13 how many additional heads are needed?
A. 1
B. 2
C. 3
D. 4
That may not have been the exact wording, but it was something similar. In this case, if I was at my computer working on a drawing or whatever, and could see the pocket, prehaps I would understand it better. But sitting in a testing center at a computer, reading words, every answer I seemed to come up with was not listed as an answer.
@TravisMack Thanks for the suggestion, but I honestly don't know if there are any I can challenge or not. It is hard to say, when you don't know what questions you missed.
@NewtonFP Most of the guys around my area don't seem to willing to help. I do have a friend that is a FPE that will provide me with some tutoring, I just haven't taken advantage of that yet. I didn't think I need to for the IIIA test. I had already discussed setting something up for the IIIB test, which just haven't made it that far yet. I would be interested in study materials, if you can part with them, provided it isn't something I already have. I will msg you.
@Jeremy No worries, I knew what you meant. And congrats on passing. I have no intentions of giving up. I have been with this company for 16 years. At least 10 of that was in the field, installing, but I moved from that to design many years ago. I love what I do, and anticipate doing it until the day I die. It is just a bummer, because it makes you feel inferior. But, when I came in yesterday and told my boss I failed, he reiterated 4 points to me:
1. I am still the smartest guy in the company (in his opinion--those were his words, not mine. I certainly wasn't feeling it yesterday.)
2. If it was easy, everybody would do it.
3. I am still certified as a Level II. They can't take that away for failing a test.
4. I am trying to better myself. There is no shame in that. Keep trying to move up, and be better.
Which I thought was pretty cool, and gave me some of my confidence back.
With all this being said, I probably never should have taken the test Tuesday. Monday our septic tank backed up at the house. We had to have the tank pumped, and have a plumber come out and snake the lines, and it was just an utter and complete mess. I never hit the shower until 10:15 that night. I should have canceled. It was too much chaos. But doing so would have made me feel like i was making excuses. Just like even typing this last paragraph does. Work isn't always calm, and I should be able to work through the chaos. It probably was too much of a distraction. But I am not blaming it on that. I blew it, and will just have to try harder next time...

RE: Water based systems layout Level III
If I had no clue on this, I would approach it in this manner.
1 - As far as I know, there is no difference in NFPA 20 for suction piping on diesel or electric pumps. So, that eliminates A/B. 2 - A vertical Turbine is installed in a water storage tank, so there is no connection to the city main.
3 - That leaves only a vertical inline. Also, a vertical inline has more flexibility with the orientation of the elbows in the suction piping.

RE: Water based systems layout Level III
That does make the most sense. I guess I spent too much time looking in the book for the answer, in black and white, and not enough time using logic.
RE: Water based systems layout Level III
Also an important note is the OS&Y in the suction piping. If this were a butterfly there needs to be 50' between the butterfly valve and the suction flange of the fire pump.
I would guess 1 sprinkler on the ceiling pocket. It is too large to omit sprinklers and taking the allowed spacing of standard spray leaves me with a single sprinkler in the center which is likely not practical since expensive light fixtures usually hang there. Ref NFPA Fig. 8.6.4.1.1.3(B) where X<36" in this case. Practically I would answer 4. The correct answer is likely 1 because nothing was stated about fixtures.
RE: Water based systems layout Level III
Studying for the PE exam now where only hardcopy books are allowed. I plan to take the Level IV exam next year so wondering how to best study for that.
RE: Water based systems layout Level III
RE: Water based systems layout Level III
Points I focused on:
1. Storage! - I highlighted everything related to reduction and modifications to density/areas
- They like to ask storage questions that aren't exactly straight forward. Having quick reference to the code that reduce density requirements helped me. Being well versed in which storage chapter/section you need to be in helps too.
2. Standpipe - The two main points to highlight here are the water demand and design requirement. Know sprinkler/unsprinklered max demand. Know how much gpm per stp/riser. I went through the book and highlighted the key numbers in this area. Super useful.
3. Fire Pumps - They didn't get too crazy on the questions here. A lot of the pump questions were related to water supply/demand, so knowing churn/rated/150% was important. An example would be they would ask you to use the city supply plus the pump supply to calculate the final pressure at a certain elevation, given a specific flow.
There are obviously questions that cover other parts of NFPA 13, but I didn't find those much harder than Level II.
I'd be willing to answer questions if anyone has any. I didn't know anyone else that had taken or passed the test when I took it, so felt like I was going in blind.

Thanks to someone on this forum who mentored me about 7 years ago, I am pretty well versed in the hydraulics portion. I am more concerned with the General Plans portion.
I agree that the Firetech course seems to cover every possible topic ranging from cooling towers & tanks to exposure protection. It is a LOT of material.

Having passed the element testing decades ago I assume once you pass the general plans you'll be a level III?

RE: Water based systems layout Level III
reading through this thread has been very helpful... I've felt very frustrated with this exam.... I passed the hydraulics portion of level 3 with 30 minutes to spare; but regarding the layout portion I am embarrassed to say that I have one more try remaining (fourth attempt) after which if I fail again I will have to wait 2 years to try again. I hear in July that NICET will be switching to 2016 Code year. so here is the delima wait to take it with a fresh 2016 test or study hard again and try for the fourth time before it changes? (if I fail i suppose it would be good to let 2016 code commit to memory over the 2 year probation) for each attempt I had studied through the material provided by Firetech; passed all the practice exams with flying colors. I'm thinking I'll reschedule for May but I am not certain. thoughts? Any more advice? Anyone have knowledge of Study material or classes?

I'm curious, what part of the Level 3 exam do you think is not representative of what designer's won't normally encounter? I haven't taken the exam in years and felt it was a pretty broad representation of the type of work that is considered fire sprinkler system design. Maybe it has changed??

I have seen some Level 3 and Level 4 with what I consider rudimentary knowledge compared to their certification level. So, I am not saying you are necessarily wrong. I just wonder how you got to that point?

RE: Water based systems layout Level III
Without getting into too much detail; questions regarding testing, maintenance & installation sequence. (all areas I am not well versed in as a remote consulting designer)
possibly was the test you and the others you spoke of work element based?
RE: Water based systems layout Level III
I am a remote designer as well and I get into those aspects on some projects. You have to remember that this test is for industry wide. I have never drawn a marine system, but I knew to study and review those requirements and know where to find them prior to taking the test.
The test is based on things that design techs see every day, just may not be the same things that you and I see every day. If I only do foam systems for air craft hangars everyday, I may not be too up on the requirements of residential sprinklers in a 13 system. But, I should know where to find them as a Level 3 or 4. That was my only point.
Again, not picking on your comments. I have been curious about all of the comments since it went to this current testing style. There seem to be a lot of pros AND cons compared to the old format.

RE: Water based systems layout Level III
RE: Water based systems layout Level III
TravisMack, to answer your question specifically,I have personally talked to several people who have taken the test and have not yet passed. They left feeling like the test was a measure of their ability to take a test,at least to some degree, and not just a knowledge of fire protection. I too have encountered level IV's who cant design their way out of a wet paper sack, so I cant help but wonder myself. DennisR4 mentioned to watch the wording, and that is also some of the same thing I have heard from others. Maybe I have a skewed perspective, but in a timed test, especially one at the complexity of the Level III exam, it seems to me that the questions should be clear and concise. I have no issue with the level of difficulty, and I fully expect it to test our knowledge of fire protection, especially on things like how to use the standards in areas we might not encounter often.
Also, on my Level II exam, I felt like there were some questions where there really wasn't a clear right or wrong answer, or that there could have been more than one right answer on questions where the test was seeking a single correct answer. The combination of things leads me to believe that it is just not about a knowledge of fire protection.
I will be taking the NICET practice exam for Level 3 General plans soon and I will post my thoughts. (I know we cant post specifics, but general thoughts)

I did an impromptu 90 min video on hyd calc for simple tree systems for one of my clients last year. He called me up and said he was needing to review for his calc test and asked if I knew anyone that could teach it. Well, about 30 minutes later we did this video. Feel free to review it. If it helps, cool. If not just hit stop

RE: Water based systems layout Level III
Yes sir, you are exactly right. However, when comparing the two editions of the standards, the location of tables, footnotes, and other important data may be in a different location. Entire chapters may be numbered differently, paragraphs expanded, deleted or otherwise modified etc.
As you mentioned, the process for calculating the specific flow and pressure required at a point in the system has not changed. The data needed to arrive at the calculation criteria may have, or at least its location within the standards, and that is one source of my frustration. I apologize if I seemed sarcastic in my statement as it was not intended that way. I am just venting a little frustration at the fact that there really is no good way to tell if you are adequately prepared for the exam other than taking it.

RE: Water based systems layout Level III
That was a year ago and my company rightfully is pushing me to finish up so I can sign drawings in my state and many other benefits. I know many ppl and friends of mine that have struggled hard with level III but there is soooo much to be had for accomplishing this cert.
After taking time off to focus on my crazy schedule I have decided that it's all or nothing, back to the drawing board I will not back down. My issue is simply getting overwhelmed and forgetting things knowing a clock is ticking and panicking. I am not that person in any aspect in my life but it seems at that moment it gets to me, and in general I have never been a good test taker.
But after 23 years I will not wait anymore or back down. Next time I see my design friends I will have that locked up. Looking forward to posting a sucessful test very soon!!
Thanks

Also, anybody remember how long it took them to receive certification? Not how long it took you to pass the tests, but rather how long after the test you got your official certification? I passed my second test February 13th, and am still listed as "pending" on the website. I spoke with a woman in NICET's office, and she informed me they had 90 days to review my experience application, which would put them at May 13th. I honestly don't remember it taking that long for level 1 or 2. Can they really be that busy? And I don't ask that to be a smarta$$. If the numbers I have seen in other posts about the number of certified technicians are out there, could they really have that many applications to look at?
RE: Water based systems layout Level III
It typically takes 90 days but you can pay $200 or $250 to have it processed much quicker.

Domain:
-Code and Standards (75% correct) NICET claims domain is (7%-10% of overall questions).
-Survey Existing Conditions (63% correct) NICET claims domain is (10%-15% of overall questions).
-Project Management (80% correct) NICET claims domain is (7%-10% of overall questions).
-Contract Documents (75% correct) NICET claims domain is (7%-10% of overall questions).
-System Layout (73% correct) NICET claims domain is (60%-70% of overall questions).
They say they score it out of 700 with a 500 being a passing score which is approximately a 71%. (I got a 463).
Given the worst case scenario where the domain I scored the highest on was worth the least % of the questions asked and the domain I scored the lowest in was worth the highest % of questions asked I would have scored above a 71% overall.
Unless some questions are worth fewer points I guess it makes sense (which is probably the case). But still, if you got over 71% of the questions right I thought for sure you would pass...
Besides all of my complaining does anyone have any advice on how I should study more for the General Plans Section? They had some tough questions on modifying existing systems in renovated buildings. I guess I could focus more on that.
