Instructions and Help about Form 2220 Foundations

Welcome back to the high performance home build today is the first day of concrete pour so the tiny lab doesn't have a traditional foundation so this is my first experience seeing a concrete pour we're gonna have some footage of that I'm gonna tell you a lot of the things that I've learned about foundations which is not necessarily what people will tell you and just to get the record straight number one we're using forma drain as the forms that is a lot what this is going to be about because all the extra steps that we took on the footings were because of this special process that we wanted to use the form a drain process and also limit make clear that I really like my contractor my foundation contractor I really lucked out he is very accommodating he will do whatever I want but like any contractor like any thinking person he will first say are you sure that's what you want because uh uh and these are the reasons that we'd normally do it another way and you need you will be putting up with it so what I've learned time and again is if I'm not on-site advocating for myself and making sure that things happen exactly the way that I want them to that it's just not going to happen and so if you are not your own general contractor because I in in my opinion you the owner of the property have the most interest in making sure that this thing works exactly the way that you wanted to if you're a nerd like me and you really want to tune the invisible dynamics you got to get all invisible right first you need to have somebody there to advocate for you if you can't be there so I'm taking a year off work to do this I would be paying somebody what I make in a year to do this for me so it's to me it's break-even it's a silly thing to even worry about but you need to just be there every day and the fact that I've been here shoveling gravel and running tractors and driving this gets deer and shut you know digging holes and things like that is where all of the experience comes from so please just make sure that you know that actual experience is very important actual scientific research that you read I'm not a researcher I read the research and I asked researchers is it very important and putting those things together in the field is what it's all about so let's go ahead and show you around well you see here are the strip footings this is the the foot that the entire house is gonna sit on above this is gonna be a foundation wall that's gonna be tied into this with pieces of rebar when we pour today back here we've got a pier a pier is like a column that's gonna be holding up pieces of the floor that are going long spans without support so we've got quite a lot of piers we got ten piers in here some of them are three foot by three foot by 12 inches deep some of them are 2 by 2 all of that was specified by a structural engineer I had an actual person who does math for a living calculate the weight of everything in the house and tell me exactly how big those need to be I would not recommend anybody guess on any of that stuff now the strip footings first of all it's not gonna be level this is what the first interesting thing that I came up against is that we worked so hard to get this as you know from the other videos we dug way down because somebody had buried a bunch of trash here somebody we also found a bunch of rocks that were huge over there and we had to we couldn't dig down through the rocks that was just not I wasn't interested in that so we had to make the lowest point of the foundation for it to be flat the height of the rock top so we're actually resting on rock over there here we raised up with very expensive dirt that I had to truck in paid for the trucks paid for the skid steer to spread it paid for the soil compactor to run around and compact everything and then it rained and as you saw in the last video with geotechnical engineer we had to then dig down again that all being said I understand why almost everyone digs down for footings instead of forming up which is what we're doing here they would just dig a trench that is in this case eight inches deep and 16 inches wide for the strip footing because we had to do that anyway it turns out so after we had already spent all this money we then proceeded to dig like you would we did not then proceeded to pour the footing into that hole what we did is fill it with gravel which is not going to get acted any more than it is i temped it down and it's sitting in there so now we've got this resting on nice hard dirt at the bottom and I know that because I tested it my geotechnical engineer Jeff taught me how to with a piece of rebar that's an l press into it and you really can tell the difference if you go out in your yard and you press down with this in topsoil it would sink down 12 inches once we're down at really hard soil if it goes in further than two-three inches tops it's too soft you should be able to really almost rest your entire body weight on this thing and not have it go down very deep at
