How To Lay Out Walls, Floors, and Roofs | Explaining Layout

Eric here with the Perkins builder brothers today's video is gonna be all about layout so if you're gonna build a house or a deck or a shed or anything you need to know about layout for your floors walls and roof so we're gonna break this down into three parts why you need a layout the different types of layouts the common types and number three how to lay things out on ciner and that's the biggest mystery that I found hiring new people to work for us you could be making more money if you're in the construction field and you learn how to do this correctly your boss is gonna really appreciate it okay part one why do you need layout and that's so that your walls have an even uniform strength there's a stud equally spaced all through the walls or a floor joist equally spaced all through the floor two has a uniform strength number two is that those spaces will line up on every floor floor to floor if you keep them all in the same layout so your floor joists then your studs then your rafters are all lined up so there is an even open Bay for your mechanical systems or your wires to run through your walls through your floors through your roof without something getting in the way and your mechanical contractors getting really ticked off at you and number three this is really important if you do your layout correctly all of your sheet goods will fit on to your studs floor joists and rafters without having to cut them you're eight foot lengths and you're four foot lengths will break evenly in the middle of a stud rafter or floor joist and that's super important for your sheathing and also your drywall so you don't have to measure or cut all your sheets you can just throw down full sheets and get on okay let's roll on with part do part two and that is the three most common types of layout that is 16 inches on center 24 inches on center in nineteen point two inches on sinners with 16 inches on center you're gonna break eight feet into six even spaces with nineteen point two on center you're gonna break eight feet into five even spaces and with two foot on center you're gonna break eight feet into four even spaces and why does that matter well it matters because most of your sheet goods like your plywood or your sheetrock are eight foot increments and that makes it easy to put your sheet goods on the wall okay let's expand on that a little bit some of your finer sheet goods like this Advantech subflooring actually have all of the common types of layout put on them so I'm going to pull a tape across here so we can check that out we're gonna have circles and they're breaking on your 16 inch increments we're gonna have nineteen point two and by the way if you can zoom in that's that little diamond you see on your tape measure there those are all your nineteen point twos so you have nineteen point two on the diamonds then we're gonna scroll on down to the squares those are your two foot centers and if we keep going you'll have again a circle sixteen you'll have a diamond nineteen point two square twenty-four and if we go all the way to the end you see that this sheet is eight foot long and there's something very special about eight foot and I want to show it to you so let's come in here eight foot just happens to be your diamond which is right there it happens to be your red number which is your sixteen and it's also your black number which is your two foot so that is why eight foot is so important and that that's why these three most common types of layouts all break on that and that's why they do [Music] okay part three let's talk about the more confusing or more elusive part of this and that's putting studs or floor joists or rafters on sinner let's show you how to do that I'm gonna hook on this mock plate and this would be as if I'm hooking on the outside of the structure and pulling across we're gonna mark 16 inch Center okay that's 16 inches but we don't want our stud edge on this mark and we need a mark to align our stud edge because that's what you can see so I'm gonna mark 3/4 back from that 15 and 1/4 and the stud actually goes here that will break this stud 3/4 on either side of this Center mark and the reason you mark the edge and not the center is that when you install a stud you can still see that line and you can use it to line up the framing square with the plate as in this way you can tell that it's where it's supposed to be if you would have made that mark underneath the center like right through here that mark would be not visible as soon as you put this in wouldn't be much good to you now you can mark one side or the other side or both sides you really only need one side and so we're gonna go on down through here there's stud number 132 go back 3/4 there's your stud on Center 48 go back 3/4 that's your stud on Center and we'll go on down this is called quarters set ahead is what I've had a builder tell me before quarter set ahead is the name of this because you go from the quarter that's back from your increment ok and what I want you to notice and this is super important as the whole point of this is that this gets the 8-foot stud I'll mark both sides of this exactly centered on the end of your sheet goods right here so the center of the sheet good will break exactly in the center your stud and that's super important because now we can start with our next sheet good going this way and it will have something to bear on which is the whole point of this and I hope everybody can understand that from what I just said okay let me talk to you about one other really quick important thing and that's cutting your plates to the right length I like to cut the plates to exactly 16 feet or exactly 8 feet if you can most plates do not come exactly 8 or 16 feet even though that's the nominal length let's check this one all right 16 and 3/8 is what this plate measures from the factory so we're gonna clip that at 16 even the reason being when we but our tape into the end of this plate to lay out our next wall our tape will already be on center of layout to make a quick note that the stud on the outside of your structure will not split on center it will actually have the edge on the center because you don't want your stud sticking out 3/4 passed the rest of your structure before I do the regular layout what I usually do is lay out all the windows and the doors in the wall so don't get confused with these while I'm doing that I'm gonna do one for you so you can kind of get the general gist of how that happens I'm gonna mark a center point for a door and we'll do CL for centerline I'm gonna do a say an exterior door 36 inch door be a 38 inch rough opening 2 inches extra on your door openings so that's 19 inches either side of Center I'm going to make a mark at 0 with my tape held centered on 19 and a market 38 and either side of those will be your jack which is a J I can't write it upside down and then we're gonna go an inch and a half and a king stud so we're gonna go Jack it's done that's one side then we're gonna come over here same thing Jack inch and a half three inches King stud okay so now we have our two jacks and we have a 38 inch rough opening for a 36 inch door to fit in this opening over top of this door I'm gonna change my X's 2 C's and that stands for and those are the little blocks that go in above or below your header to finish the wall to the top plate above your door okay I'm gonna show you a bit of framing that we've already got done on this project and how the studs break on Center so to the outside structure which is the inside of the wall sheathing and run our tape out here you'll see that our studs are breaking exactly centered on 32 48 16 you could pan down here and so these studs are all on center so they line up with all the rests of framing on the rest of the house okay I do want to note that in a lot of cases we use a combination of layouts for instance these rafters they're there and in the middle are 24 inches on center these studs there there there there are 16 inches on center and this rafter will break right in the center of this stud Bay that's okay because this wall 16 inch on center with a double top plate has enough structural strength with the double top plate to carry that load thanks for watching my video today I hope it gave you a little more insight into why you do different layouts and how to do layout and how to do on center correctly remember to subscribe to our channel click the bell so you get our future videos peace see ya you
