Topic: What Is This?

[Rob...]

The sanitary and vent pipes in plumbing chase are drawn "correctly". The line represents a sanitary line.

What is your interpretation?

Is it drawn correctly?

Would you draw it this way?

[Matt__W]

It COULD be correct, but I would think that the vent stacks (in this case) would be combined into a single.  Are there details calling out more info??

[Rob...]

No.

If it is drawn correctly and you were to model this? How would you do it?

[Matt__W]

This is how typically will show the waste/sanitary and vents.  Keep in mind it may not be modeled correctly because at the end of the day it's still the 2D plans that buy the job.

The brown lines are vents (they're usually dashed because it's a short segment it shows as solid) and the green lines are sanitary/waste.

[Rob...]

Can you show me 3D view?

[CAB]

I would think your looks somewhat like this Rob.

[Matt__W]

Can you show me 3D view?

I'd like to.... but I can't.   Seems whoever "modeled" this, only modeled the H&CW piping (blue & red lines).  The sanitary and vents are detail lines.   

[Bob Garner]

Even on the 2d building plans I work with, they draw the vent stacks and related in a 3d view (drawn in 2d CAD).  I have trouble seeing what you have there in 2d only.

I have trouble seeing what you have there in 2d only.

I agree but was told it is drawn correctly.

This is what I modeled in order to replicate the symbology in Revit. It's over simplified but I'm not trying to model it for the project. I'm just trying to demonstrate why the 2D does not reflect the intent.

[Matt__W]

That's what I "saw in 3D" when I looked at your 2D image.  It don't make no sense!

[Rob...]

I think the intent is for the san and vent to go up and down at the side away from the corridor and the supplies.

How would you show that in 2D, presented without the offsets like the image in my first post?

[CAB]

Wouldn't it look like this?

[Rob...]

I meant the bathrooms shown above in plan view, sorry. Some more info is that there is identical bathrooms above and below.

I'll post an isometric tomorrow.

[CAB]

OK stacked I would do like this:

[Krushert]

Maybe they intend to tie it into one of those new recirculating waste heat energy recovery pumps?   

[Rob...]

CAB, I'm pretty sure that is close. I believe the intent is to combine the two san risers. Same with the vent. Both risers will be on the same end of the chase so that a duct can run across the other end.

[Matt__W]

Maybe they intend to tie it into one of those new recirculating waste heat energy recovery pumps?

Can you get a LEED credit for that?  A building heated by poop?

Waste Wattage: Cities Aim to Flush Heat Energy Out of Sewers

[Rob...]

I finally got an answer. There are only two risers, one san and one vent at the same end of the chase.

Thanks all for confirming my confusion as to the drawing I posted.

Huh.   No sh!t?   

[CAB]

So like this?

[Rob...]

That looks like it.

Do you think the plan I posted represents that?

[CAB]

I would think this is what the plan view would show,
but as you know the plan view is symbolic only and not real world.

[Rob...]

I agree.

After I questioned the four riser symbols that are "correct", he said, "Those aren’t riser symbols, that indicates a pipe."

Here's some more of the exchange:

"Those aren’t riser symbols, that indicates a pipe."

Ummmmm......  *scratches head*

[Rob...]

It was worse than head scratching. I was banging my head against a wall trying to figure out how to respond to that without insulting him.
