Roofing invoice example for Engineering

hey class and welcome to this little quick video on how we think about takeoffs for framing so framing really unlocks how you can you know construct the structure it talks about walls roofs floors and knowing how these walls are constructed is a big part of figuring out how much things cost we learned about how they're insulated how they're clad so the floor plans are a great place to start when you're doing framing takeoffs and there are two things we use to do takeoffs for framing we use linear feet for things like walls we use linear feet for things like interior partitions and we also use things like area for figuring out what the area of the floor plate is or the or the roof assembly and that helps us figure out things like the amount of sheathing we need adhesive to adhere that sheeting down to the floor joist in this case i've got an engineered tgi and then based on the area divided by 16 foot centers how many tgis i need to make that floor so let's kind of go through some of my work here so before you got here what i've done is i've worked around my perimeter of my structure measuring to the exterior and i've taken all those dimensions you know with a 3 8 scale i use my red dot little trick i scale what the length of that wall was from sheathing to sheathing because that's how long my plate will run and i've written those dimensions down so 28 14 28 14. my second floor has a cantilever so i've scaled that and realized that that is 30 feet long upstairs 14 14 30 feet so those are my linear takeoffs for walls the next thing i did is i grabbed my red pen and i looked at my interior partitions so in this case i have a couple types i've got p1 and ip3 and i worked around with my scale again grab my my red little trick here and if i scale three feet i wrote three feet three feet wrote three feet scale the partition i got 27. see every time i'm scaling something i'm leaving that dimension along that wall so i never have to scale it again when it comes down to recording a master sheet it's always on the page coming up stairs again same thing scaled all my partitions left all the notes there so that allows me now to summarize how many linear feet of you know p1 i have p3 i have and then do some costing the next thing i did just to finish my takeoffs was i also have aside from walls and floor i have some structural things so i took my orange marker which is just my little structural note so i took orange and any note that's structural i circled in orange so i've got a nice little handy framing schedule down here it shows me that i've got both floor joists i've got some beams i've got posts and i've got lintels so i worked around and i circled all the lentils so i've got l2 and i've got l2 in the rear i also got some posts so i circled those i came down the first floor and i work around the perimeter so i've got b1 p1 p1 b1 l2 b1 b1 b1 and l1 so next i did is to figure out well how many what's the linear length of b1 i have because i'm going to buy that b material by linears by linear feet so i grabbed my red pen grabbed my scale and i simply scaled all the lintels all the beams on each floor wrote those down so if it's pointing at b1 i read in this case temp with 6 pointed b1 same thing for b1 back here l2 etc so now i'm ready to sum those the last thing i have is i have posts so i have posts here and there on the second floor so you can do almost everything you need from from one plan or the floor plan for framing takeoffs but what you don't know is for this 30 foot long wall you know by you know divide by 16 inches to figure out how many studs you need you can calculate the interview to plate but what you don't know is what length of stud do you need and when you have the length of the wall what's the height of the wall to give you the area of the sheathing so what we use for that is we use our sections so we flip to our section drawings and for me that's on a2.0 and i can take my scale and i can take my scale of my outside wall so the main floor from the base top of the foundation wall to bottom of that plate i have a seven foot stud so i can use eight foot studs for that upstairs centipede again i can use eight foot for that on the exterior of that second floor because i've got this two percent slope i have to use a ten foot stud and on the same side back here i can use an a foot stud so if i take those dimensions back i can relate this back to my plan to say my first floor up here this is eight feet throughout so eight feet tall throughout and back here i've got eight feet on the low side but back here because i've got this two percent slope i've got to use a ten foot stud so this is ten foot tall this is ten foot tall and this is tempeh tall so when i'm listing my different wall walls to calculate linear lengths i've got to take into account the height so main floor here i've got 28 28 14 and 14. they're all eight feet and i'm going to record them by their wall type so w1 up top i have 28 feet so at eight feet tall i have 28 feet of that wall type w1a which is my it's a fire rated assembly i've also got 28 feet w2 is my end walls and it's 14 14. guess what it's also 28. p1 i've got a partition here i've only got three feet of that wall that's also eight feet because all the main floor p3 i've got 27 feet and three feet that's 30 feet total also eight feet upstairs it's a bit of a different story because i'm working with both an eight foot wall and i've got ten foot because i've got this two percent slope on my on my roof you know that you can see if i flip my elevation here for you i can show you that i start eight feet down here but i grow up to 10 feet so it's important note 8 feet here 10 feet and 10 feet so i've got w1 in the back i'm going to record it by length so 30 feet at 8 feet tall so w1 8 feet 30 feet w [Music] 1 at 10 feet i've got 20. and that is plus this by the back i've got 30 more so i've got 50. 50 feet there p1 i can add up all my partitions so i've got 2 this is 12 18.5 22.5 33 41.5 and 47.5 so 47.5 and then p4 but there's a little knee wall around the stair i've got 10 and a half and 13 so i have 13.5 so all linear lengths if i want to remind myself you know i can write ln dot ft so that's linear feet i can say that's throughout okay so all my framing take off by linear foot now i want to get the area of my second floor plate so i can confirm in my floor schedule what is constructed from and because i'm platform framing which i can confirm with a section you know i frame the first four walls and my perimeter of my room joist and sheathing goes right the outside of that wall so i want to do my take off for my second floor plate right to the extent of the sheathing not the inside of that wall so what i do typically is i grab my handy dandy square i'll go corner to corner i've already done this but i'll do it again i go right to the sheathing and i go all the way through do the same thing on that side and always leave your marks your lines on the page and to remind you where you took those sheathing lines from so i go side to side and i want to figure out well how much sheathing do i need so it's 30 times 14. multiply that together i get 420 and i leave my math right in the center so 420 square so for f2 i have 4 20 square feet so when i get to sheathing and joists i can calculate that the next thing i do in this plan is i look at my things like my my beams so i've gone through a blank i've measured everything i've taken all the lengths and added them up so b1 i took all my beams from the second floor and i have 58 and a half feet my posts i took my one two three four i went to my section i confirmed they're eight feet tall so i have four at eight feet and i took my lentils same thing listen them down so all my firming takeoffs are basically complete for my walls floor posts beams and lintels the last thing i have to do is my roof and the best place to do that is on the roof clan itself so same thing i would take my my line i mark corner to corner because i want to know sheathing area for the roof in this case when i did this earlier i got 458.5 square now the thing you need to keep in mind with roofs is on any pitched area the dimensions you're seeing here is the orthographic dimension it's what it looks like but look at the plan straight down so if i take this square let's say this is 12 inches if i tip this up towards the camera that you're seeing overhead right now this looks a lot smaller it probably looks like it's only six inches long that's because you're seeing the orthographic projection of that slope if i flip it flat again you see it's much bigger so this roof is on a two percent slope so the dimensions you're seeing is the orthographic dimension it's looking straight down you need to know if you laid that roof flat because you have to sheath the roof flat how much air do you need so i take my 458 and have to figure out how much do i add to this to take into account that roof slope so i look at things like my slope here which is 2 inches to 1 foot which is a 212 roof i look up my roof factor and i'd multiply 458 0.5 by whatever my roof factor is so i look that up online i get equals and i get the actual area and that's the actual area that i take into account so you always want to take into account that roof slope if it's a 1 12 pitch i believe the multiplier is 1.0035 if you had a 12 12 pitch so very steep you'd multiply the orthographic area by the root factor for 112 which is 1.4142 so almost one and a half times the orthogonal projection is what you need for area so you look up two percent whatever slope you have look at the roof factor and multiply that factor by the orthographic area and that's going to be my area 4 in this case my r1 assembly so once i get that done i'm basically done my framing takeoffs and i can start to break down what each wall is so w1 having plates studs sheathing nails adhesive sheathing tape for air barrier break that all down in my estimate it's all from these quantities so walls linear feet floors area roof area and structural we're going linear feet as well so beams lentils and posts hope that's helpful have fun breaking up framing is really exciting because you're to learn how the structure is built and once you get head around it it can be quite an enjoyable thing to do okay have fun
