so here is our plumbing right line 184 Plumbing it says building uh C and D rough topout water heaters and trim labor so what they first do is rough right that is everything that is you cannot see it's underground and it's in the walls that is a rough um so that's what I want to talk to you and show you about today so there is a bid of 22,900 in here again this for two buildings so it's about 126 per building for are plumbing and again not just a random number let's find out why did they get to this number right so let's pull up the plumers bid and then let's talk about the uh why the plumbers gave that bid okay so here is our plumbers bid so it says this is for one Mansion 16 bathroom units each unit has one toilet one laboratory one shower we have two washing machines we have two utility sinks we have hose bib and I add I told him to add more than one um we have a three compartment sink here with a floor drain and this is a note that I I changed the way this was set up and I'll talk to you about that uh hand washing sink again this is required for me specifically um then they're also doing the the gas right so my site does not have natural gas we put in a propane tank or a yeah yeah we put in propane tank um they have to run that Plumbing or that piping for that then you have my water heaters I specifically have two water heaters this one right here this model for the each wing of the house and then I have one water heater for my kitchen and again I chose these specifically based on my local Health Department's requirement that they wanted a separate water heater for my kitchen if you don't have that requirement you may not need a third water heater right there there's costs you can change there and they pick this again specifically because it's on the MEP document which we'll talk about next so Pex piping um and then owner to install fixures so when we look at this I have a that 126 number and then I also have a another number of I want to say it's is it on here 25 Grand or something like that oh here it is fixture allowance 50,000 so I have 25,000 per Mansion to provide the fixtures which are the faucets um the the handles to the the shower um all of that kind of stuff that that is that one I want to pick exactly what I want to pick and so I have $25,000 budget to do that and I can go over that and spend more I can go under that and I can get money back so let's talk through why the plumber bid it like this and it is entirely because our Builder sent him the MEP specs for this building so this is right here right so again another type of engineer that's MEP mechanical electrical Plumbing right this is here for you to review um you will probably have somebody use this or make their own on it but you can at least have this as an example but it'll it'll detail all of the different lightings and everything so I want to specifically talk about plumbing and then how the plumber read through this and then said okay now I understand the scope of work now let me give you a bid so as we're looking through here you see like e down in the corner so we're talking about electrical until we get to the P part so that's mechanical now we're in P right so let me Zoom a little bit more you can see p for plumbing so domestic water plan this is incoming water then we have down here Wastewater plan so this is my rough plumbing this is the drainage okay we'll talk about that and then there's also other diagrams um going through here's my propane and then other stuff so let's talk here first because this is the first thing they put in right this is the rough plumbing this is the drainage and you can actually see they're not it's not a mystery to them how we're going to do this the engineer designed all of the drainage so I have videos actually showing here's what the drainage looks like before they cover with concrete here's what it looks like after they covered it with concrete so your design could be different than mine but let me talk to you about my design here I have eight bedrooms on this side and these lines all run together and they go out the building here now again I'm on septic so I have my tanks in the backyard if you're on city sewer and it's in the front then all of these pipes would go out the front of the building they connect somewhere go out the front of the building connect to the to the um city services there so I have these eight connected here right you see all these lines let me zoom in just so you can be super clear on this like this toilet line it connects to this toilet line it connects to that shower you know it all connects goes down here this Wing over here connects it all drains this way all right goes out of the building this two little circles here this is a double cleanout and then it connects over here it stops right because this is where the for me the um utility person who would be the septic he's going to pick it off here my plumber stops here and the septic is going to connect and bring it to my septic tank which is going to be out here so that's eight rooms on that side then I have eight rooms on this side right you can see here's the farthest one it's running this way this is a little cleanout right here where they can snake it if they need to so these are running underground they're putting all of this in before they put the concrete foundation this is going to be underneath that right all of this comes there it turns that way these bedrooms over here come this way here's you can see another little cleanout right there con connects and comes down this way here's another double cleanout right there um and it's connecting this way into the backyard again the septic guys for us is going to pick it up here and those pipes are going to connect to each other before they go into the tank then in the center of the building I don't have much Plumbing I just have my kitchen and I have my salon so these there is a pipe that goes from here to here it's on a different drawing they left it off this one for some reason is a mistake but this is going to come this way underground go out the building they drew this in here as a grease trap I'm not putting in a grease trap but I had them intentionally leave it in case any requirements did come up for me to put one in um and again same kind of thing for you right I kept this line separate on the kitchen because my health department um May it was kind of a gray area um may have wanted me to put a grease trrap in and you wouldn't want all your showers and everything going to your grease trrap it's really just for a commercial kitchen um we don't have to do that but this is why we designed it this way because if they did come back and say hey you know what we we do want you do that it'd be no big deal I can put it right there in the design this is be before we start you know actually building this and I don't have to separate anything so really this is the way it's designed you have eight rooms that drain out this way eight rooms that drain out this way and your kitchen Salon that draon here all three of these come together meet and then go into our septic and our septic designer designs it from here it picks up from here it would be the same if you have sewer your civil engineer would say hey we are taking these it would probably be in the front or maybe in the back wherever your sewer line is and we're going to connect to the city services that's what the civil engineer would would put all those utility kind of stuff in so my plumber can look at this and and you know they have formulas they they pay this in CAD right and they can put in their thing and they can measure they'll know all the lengths of these pipes they'll know how much they need um they then they'll go and and say okay here's what it costs for materials here's what it costs for labor right here is this part of this as we look further here let's go up one this is my domestic water plan this is the drinkable water right it referenced that it had to be in um well he said it was in PEX right so that's because it said here in this drawing we wanted inex if if you don't use PEX in your area if you use you know copper or something like that your engineer will reference that and then your Builder your your plumber will read that and say okay I'm going to bid this in peex or in Copper or whatever it is so here's what it looks like you you can see water heater here you can see the lines right the water lines these are again going to be in the Attic they they are not building this before concrete they'll do all the framing and then put this stuff in right but you can see here's all the water lines how they go where they are all going to be at so it's not arbitrary based on square footage or anything for your plumber he can maybe give you an an kind of a round number Price square square foot for Plumbing on the front side but he really needs to have this plan it tells him exactly what goes where how much pipe all those kind of things and it details all of those things here on these drawings so to kind of expand a little further I'll show you here is like this kind of 3D modeling of it so this is the incoming water line so it actually comes in right the the engineer specting a 2 and 1 half inch waterline coming in right and obviously you may have certain waterline at your property that that would be important for them to know and then they'll draw based on that so you can see it coming into the building um literally underground going up into the attic and now it's feeding on a 2 and 1/2 in and then it splits this way to a 1 and 1/2 in and then it's feeding this way and then it eventually splits to a 3/4 inch and then it goes this way and then it splits to a/ inch this is when it's coming back down in the wall to go to you know your your different um showers and all that kind of stuff right says sh is going to that water closet there's a toilet going there right so you can he's not making this stuff up he knows oh I need to have half one and a half inch then to one inch then to half inch and it shows all this and he can take his CAD file and see here are the lengths of all of these type of things so it's showing where does it go into the water heater how does the hot water come back out where does all that go so that is all specked in here um and this is an important step for your me engineer to do uh you again can you can before you have this done you can get price per square foot rough estimates on these numbers um but then they they will need to know exactly how to build this thing and that is the job of this MEP engineer to show them all this kind of stuff so same this is the same kind of thing with the actual drainage part right there's two bedrooms over here in this run going out that way here six bedrooms coming together meeting going that way this is my kitchen and then this is my my other um eight bedrooms on the other Wing coming together and exiting the building so he can see okay here all the different sizes of the pipe right it it as everything comes together it gets to 6 in right before that it's a 4 in going that way it's a 4 inch going that way um these are two Ines right so this this cannot be a toilet right you can see here it says 4 in for WC so these are my toilet lines these are my either my shower and or my vanity lines and again none of this is arbitrary the plumber will know exactly what to bid and then push this thing forward and say okay now I know what to do now I can you know give you this this number for these kind of things here we go okay right here right it says Plumbing so rough this is all of the drainage that's going Behind the Walls then you have your top out right that's going to be all of your your other um poble water and the water heaters and then your trim labor this is where they're going to come back after you know all the sheetrock and everything is in this is where they're installing the toilets they're installing the the faucets they're installing all that stuff they're testing and making sure everything's working so really you can saw in our bid it said onethird of the bid gets paid after rough one/ third after topout and water is probably in the that same spot and then one/ third after trim label right so they're going to get done you know really they're doing this in stages they're going to have to come back three different times right at the front of the project they put all the rough stuff in then they leave the framers come um and then they come back they put in all the the the drinking water lines all that kind of stuff then they leave again the sheetrock guy comes all of your kitchen people come your bathroom people come then they plumber comes back a third and final time maybe not final third time and then they're putting all the fixtures the finished stuff in there the the faucets and and the stuff on the sink and all that kind of stuff and then they probably come back one more time if you have just to like punchless stuff right like here are the things that are not working right let's let's dial this in this has a leak all that kind of stuff so that's really what the plumber looks like there um we have videos that go through it'll be in the same portal here going through and showing all the different steps of this from from rough to top out to you know trim and what everything looks like additionally we have this fixture allowance here right the 25 Grand per building Laura has picked specific fixtures faucets toilets all those kind of things uh that is something that will be in here as well with with all of the specific materials you do not have to do it that way you could tell you could take those materials and you could tell your engineer hey I want these materials so put it in the plan it would go into this document here right they would literally list all of these things out in this section right here it says fixtures and equipment right like here you go you got this toilet right you have this faucet um you have this kitchen sink this showerhead so again some of these things were not what I wanted I wanted to either change them because he put something I didn't like in there um or it went out of stock or something to that effect so that's why we I separated the fixtures in an allowance from this um and you could do it either or on that hey just a question can we um like your updated list of your pictures can you provide that um yeah I think it might be a good idea to like give the guess the contractor that and just another general question I mean I am an engineer but I don't know much about house construction but do they have to because I know we're going to have the fire sprinklers and everything but do they have to go up into the attic with all the water pipes or can it just go into the walls it can be you like there's yeah because I'm just thinking from a leak standpoint I mean you know the more the less you can have an the attic the better so that I don't know I would think the opposite um it is so much easier if you have open attic space to go in and fix a leak if you because you have gravity right the if the if the pipe's above you it drops and pulls right there and then gets through the sheetrock and it drips and you know exactly where it is it's right there but if it's in a wall it's going to run down the wall to the ground around the B B forward it's going to pull for much much longer before you see it and then you're cutting open the wall versus just going around in the Attic okay yeah I guess yeah I was just thinking from that other stand yeah that's true because they the foundation so okay yeah there is multiple ways to do this and sometimes it's based on climate and freezing and stuff like that um
