How to Lay Out Water Lines in a Building Using an Architectural Model as a Reference

Planning and Executing the Water Line Layout in a Building Based on Architectural Model Insights

Explore the process of laying out main water lines and different pipelines in a building design, with particular reference to the use of architectural models as a reference. Learn how to correctly set elevations and view ranges, as well as adjusting pipe types and diameters for practical implementation.

Key Insights

  • The architectural model of a building serves as a helpful background for laying out main water lines and different runs within the structure. It provides information about fixture locations that guide the placement of these pipelines.
  • Setting the correct elevation and view range is crucial in building design. For example, if a pipe is at an elevation of nine feet six inches, setting the top of the cut plane at ten feet in the view range would allow visibility of the pipe in the floor plan view. Adjusting these settings based on requirements is an essential part of the design process.
  • It is important to ensure the correct pipe type and system type are selected before laying out pipelines. Considering factors such as the type of water system (e.g., domestic cold water) and the diameter of the pipe needed (e.g., reducing a four-inch line to a three-inch line) can contribute to a more efficient and effective design.

In the previous videos, we went ahead and kind of finished up our main water line into the building. Going forward, what we want to go ahead and do is, you know, there's different ways to attack this. But what we're going to go ahead and do is, since we have the architectural model as a background, we kind of know where some of these fixtures are, those kind of things.

We're going to start to kind of lay out our mains or our different runs in the building. So what I want to go ahead and do is I'm going to come over here to my level one floor plan. Let's take a look.

Now we have our point of connection coming into the building. Obviously, this mechanical room is going to have some other equipment that we're going to be adding in later on, water heaters, boilers, that kind of stuff. And we'll tie those items in.

But we want to kind of look at the overall what we have going on here. We'll probably end up running the water line kind of in, kind of come down, come straight across, get into the corridor. So come through the kitchen, over the cafeteria, kind of come into this corridor and start kind of distributing around.

Now we don't have to stick with just the water line. We can go with the water line and the hot water line to go ahead and do that. So right now this is sitting at an elevation of nine foot six.

Now you might be wondering, hold on a second. I can see this pipe at nine foot six in my floor plan view. Hold on, what's going on here? Before we move further, let's take a look at our view range.

If I go to my view range down here in the properties, I'm going to hit edit. And you can see here, my view range, the cut plane is at four feet. The bottom is negative four feet and I can see the negative six feet.

So I'm seeing underground, but my top of my cut plane is at 10 feet. Now, if I move this to say like eight feet and I hit apply, notice that that pipe went away because I'm below the nine foot six. So you may in some instances put this at like 10 feet or so just so that you can see that pipe.

It's really nice to have for a working view. The other aspect of this that you could do is you could have a reflected ceiling plan to where you can see these things, but we're going to go ahead and start with that. So I'm not really going to, I know I'm going to work in this room later on, so I'm going to go ahead and start just a new pipe off in the middle of nowhere.

So I'm going to go over to my systems tab. I'm going to go to pipe. Now, again, a couple of things that you want to check, you want to make sure your pipe type is correct.

We want to make sure that we're using our copper pipe type that we created. We also want to make sure that our system type is domestic cold water. Now we knew that there was a four inch line that we were bringing in.

So after everything that's happening here, we're probably going to reduce this so I can change the diameter. Let's make it a three inch. So I'm going to go ahead and make it a three inch and I'm going to start it about here for right now.

Again, this point of connection inside the building can kind of change later on. So, but we're going to come down through the kitchen and kind of get in over the cafeteria into the corridor and then work our way around. So I'm just going to go ahead and start.

Oh, let's check our elevation. That's one other thing we want to go ahead and check. So you can see our pipe is really low right now.

I'm going to go ahead and make it nine foot six just so that we can go ahead and start there. If we need to, let's the cafeteria has a higher ceiling, things like that. We can always come back and adjust that later on.

So I'm going to go ahead and start here. I'm going to come down, kind of get maybe right up against this kitchen storage area, pick there, come over, pick here. Now water pipe is fairly free flowing.

You can kind of do what you want with it, but you don't want to obviously do too much with it, but we can go ahead and to just get into this corridor. I go ahead and come down here. 45.

I'm going to come down here and I'm thinking about what I'm laying out in the future. So I know I have a bank of bathrooms here on both the first floor and the second floor. I also need to make sure I have a location to run to my second floor if I need to, but I got this here.

I'm going to go ahead and come down and then I'm going to come over and run it down. Now, since these are all at the right, the same elevation, I could go ahead. Now I can tie into this system.

So obviously I want to have a connection going down this hallway. So I can go ahead and pick here. And if I'm at the same elevation, nine foot six, my elevation is nine foot six.

Pick there, drag down, pick there. You can see when I zoom in, it automatically puts my fitting in there. Now, if I had a specialty fitting or something else that I wanted to throw in there, I could go ahead and do that.

I can just change the type properties here with that loaded fitting, but this one is perfectly fine for what we want. If I wanted to adjust the location of this pipe, I'd go ahead, select it, drag it up, drag it down. Pretty simple, pretty straightforward.

So maybe I want to tie it to this edge of the corridor a bit more. Same thing. Maybe down here.

I want to tie it to this edge of the corridor down here. And there we go. We've kind of laid out the main of our waterline.

I'll go ahead and see in the next video.
