Explore the process of designing fire sprinkler systems, where attention to detail and a keen understanding of spatial relationships are critical. Learn how design moves from theoretical to practical as we move from the library to the more straightforward design of the cafeteria area.
Key Insights
- The process of designing fire sprinkler systems often involves two designers: one conducts the initial design work and the second critiques and suggests improvements.
- Designing for different spaces, like a library or a cafeteria, requires a thorough understanding of the space, including ceiling height and placement of main lines.
- Detail lines are temporary guides that assist in the accurate placement of branch lines and sprinklers, ensuring efficient coverage for fire protection.
Note: These materials offer prospective students a preview of how our classes are structured. Students enrolled in this course will receive access to the full set of materials, including video lectures, project-based assignments, and instructor feedback.
So in the last video, you should have finished the piping in the library area. And now we'll be going up to the cafeteria. And if you've made it this far, pat yourself on the back.
You've been designing this along with me all by yourself. Now, it is good to remember, for fire sprinkler systems, generally it takes two designers. The first Designer does the design work, and then the second Designer talks about how they could have done it better.
All right, so this area should be a lot more simple than the previous area. But let's first take a section view to see what we've got going on. So I'll pull in to about right here should be okay.
If we look at here, we have a higher ceiling area in the lower ceiling area and a higher area in the back. So what we'll have to do is we'll take our main. Now we can't stay at this elevation, we're going to have to come up above the ceiling.
So go to the measure tool again. The ceiling is at 14 feet. We'll probably have our main up at around 14,8 to 15 feet, we'll confirm that in a bit.

Okay, so our Level One Piping Plan, let's go on ahead and save. Okay, so why don't we start with our main here. Currently, it's capped.
So let's delete that cap there. And we will draw pipe into the cafeteria area here. Okay, we'll start off like that.
Let's go on ahead, delete the 90. And let's elevate this piece to 14.8. Okay, now on this side, let's go on ahead and pull it till about here. And let's drag this way to about here should be good.
And now when I draw this piece to the center line here, we should have a vertical piece that connects the two. Okay, and in this case, they should be Fire Protection Tees. We can go on ahead and take a look at our 3D view.
We've got it open. There we are, we come up with a 90 and we've got a Tee. Now we just have to have our Branch Lines connecting to these sprinklers here. So far, so good.
Alright, so let's use our Detail Line tool to lay out the Branch Lines, and then we'll draw them afterwards. So I like to start with the most common denominator of sprinklers to get my eight inches. We'll start from here.
Let's go to DL, I will start at the middle of this sprinkler, find that triangle, drag it to just about here, even pull a little bit back. Okay, that's good. Then we will do another one, looks like this is the most common row.
So I'll move into this sprinkler, set my Detail Line there. Okay, let's go on ahead and copy this one, find the endpoint. Alright, and we'll go to here.
Again, find that middle point, might have to zoom in and out. And we'll do this one. Alright, escape, escape.
Let's just take a look. We should have 1,2, 3,4, 5,6, 7 Branch Lines, looks good. Let's go on ahead and select all of them.
And we will move them up eight inches. Okay, let's go to System tab, Pipe. Let's change our Fire Protection pipe type to Outlets.
We will use one-and-a-half-inch pipe. And let's have this at the same elevation. We'll choose 14, eight.
Let's not connect quite yet. We'll draw this one to about a little past the sprinkler there. Okay, now it's just a matter of copying this to the center line, the detail lines.
Alright, pretty good. Let's click on the main. We can see our Trim/Extend Multiple Elements.
Let's go ahead, click on the main. And then not the detail line, make sure you get the Branch Line. And let's connect all these into our main.
Now we're not going to cap the main here, we're actually going to be drawing this up to the gym area later on. But we'll cross that bridge when we get there. Okay, we're looking pretty good.
Now it's just a matter of connecting into. So let's go ahead and clean up a bit for our detail line. Let's find one and select all instances visible in view and delete.
They're just temporary for us to locate where we're going to place things. Alright, sprinkler connecting to and if you'd like to skip ahead, feel free. But what I'm going to do is all the sprinklers connecting to the Branch Line.
And don't forget when you're done to make them all one inch.
