The colors are pretty but it's not done according to code.

@rdeagan Why do you believe it's not drawn to code?

@rdeagan

It's been years since I've done commercial design so I don't claim to be an expert and I don't really want to look it up in the code, but if I recall correctly, floor drains are exempt from that rule for 2 reasons. First, you'd have to have a vent coming out of the floor right next to every floor drain. Second, horizontal vents for floor drains must have a WCO where they come up AFF. The WCO is there so the vent can be rodded if an overflow carries an obstruction into it.

27 toilets in the women's

7 toilets & 7 urinals in the men's

at 20 seconds you see what looks like another wall bracket in the distance

@deezynar how manytoilets?  30?

[rdeagan]

You cannot offset dry vents horizontally under the floor. They must rise at least six inches above the flood-level rim of the fixture or drain being served before offsetting.

That's pretty cool.

@TruthinFilm

2 bathrooms, 1 men's & 1 women's. There are several floor drains, a mop sink and at least 1 water fountain outside. This is pretty typical for a movie theater or even a high school cafeteria.

@rdeagan

It looks good to me. What are you seeing that I'm not?
