- When you put your posts in there first then you pour your concrete around it. If youre not careful theres really good chances that you could- Your concrete is going to move the bottom of your post around. And its going to be really easy for you to get that post out of line. So this method is a lot easier. Take some getting used to. Skill level definitely like a nine. Just kidding, you can do it. Action. Oh, that was really good wasnt it? - It was. So it was right on cue. upbeat music What were going to do is were going to go straight. Were going to go to the old line, go straight for two sections and then go to the new line. So what were doing here is we are working that way with our fence line. We have a good 600 feet strung out that direction. We have a site post down there. Theres one post that were siting to to keep this line in check. So that way were staying straight. I didnt say it, but yeah, were doing this without a string line because we dont have the time for a string line. You want to make sure and use is the same eye, but look at this side of the post and look at this side of the post and make sure that youre traveling in a straight line. And then Andrew here he goes back behind and he goes to that post and he looks back behind me to make sure that my post is correct and its hitting my target post. He gives me the thumbs up and now I can continue that direction. Yup perfect. When setting without a string you want to make sure and pay really close attention. So when youre looking at your fence line going that direction and youre working away from it, make sure that you cant see a sliver of any posts. And if you cant see a sliver of any posts then youre good. So there I had that one, I must have knocked it just a little bit in that direction and I couldnt, maybe I didnt see it there, but I saw it as soon as I started setting this one. So I gotta go back to that one and fix that before I could set this one. So now that were done setting this post, we need to go back down the fence line and I didnt set a post down here and I was wanting to show you guys why I didnt set it. So the post I didnt set is that one. And then the reason that I did not set that is because that is a terminal post or a brace post. What were going to do is were going to break the fence there. Were going to break the top rail. Were going to break the chain link and were going to break the tension wire. Why? Because thats the spec on this job. We have to break it every 250 feet. So since thats a bigger post, that is a two and seven eighths posts, and our line posts are two and three eights. Its really hard to see around that bigger post. So if you shoot through it, dont set that post. That way you can make sure your line stays straight and established. Come back after you do set this line come back and set that post. And thats exactly what were gonna do. So I dunno if you noticed this cool little thing, the skid steer going down with this really cool attachment that dispenses the concrete for us. No it does not mix the concrete because we dont have the time to do that. We just call in our concrete to our local concrete company and they bring it out to us. On this truck that we have ordered right now, we have a solid 10 yards of concrete. So its a full truck and that is going to get us a little bit more than past that fence line. For the depth of the holes that we have it should get us about 85 posts, but there is a mixed design on this and we cant just use any kind of concrete that we want. We have to use what is an approved concrete mix. And this one is approved. So therefore mixing concrete ourselves is not an option. Is that thing really worth it? Absolutely, because theres not enough people to push 85 wheelbarrows of the concrete down that. So that is a cement hog. And that thing can carry about six to seven holes worth of concrete at one time. And he just stays in there and he pours that concrete out for us and drives right down the fence line. All we do is come right behind them and set the posts. This concrete is also tested. So there is an engineer involved with this who is actually going to take samples of this concrete and takes strength samples to make sure that this concrete breaks at no less than 3000 PSI, we put a chemical in there so that way it slows down the chemical reaction or the curing process. So that way its going to stay wetter for us a little bit longer so that way we can set our posts and set our post to height. So that is one benefit to ordering concrete from a concrete company. You just- The stressful part is is if you havent done it before is knowing how to order it. Im sure you noticed by now that were not just throwing the post in the hole and pouring the concrete around it. So what were doing is we are stabbing the post in the concrete. So that way the concrete goes up inside that post and then it encases is the post all the way around it. When you put your posts in there first and you pour your concrete around it, if youre not careful theres really good chance is that you could your concrete is going to move the bottom of your post around. And its going to be really easy for you to get that post out of line. So this method is a lot easier. Take some getting used to. Skill level, definitely like a nine. Just kidding you can do it. Once you get the hang of it. Its really fun and really easy. I really enjoy setting a nice straight run of posts. Its a great time. And its just awesome to see how straight you can get it. Whichever time, straight as an arrow. Were short on concrete, we used all 10 yards of that truck, and now we can use some more. Were going to go ahead and place an order for some more. While we set the height to the stuff that we just set. So were going to go to our Construction Master Pro app on iPhone or Android, and were going to take 12 inches. Cause that is the diameter of our auger that were using. Were going to go circle circle to get the area, which is 113 square inches times. Were going to 48 inch, a four foot depth on the hole. So times 48 inches, and that gives you the cubic inches. Now were going to go to conversion yards that gives us the yardage per hole, which is 0.116355. We have 63 more holes that we can pour. So were going to take that times 63. So I need to order a truck for eight yards of concrete and thatll finish off everything that we have drilled for today. That is how you figure out how much concrete you need for how many holes you have. When we do our height the way that we do it is we measure down from the top of our posts. This is a seven foot fence were gonna measure down. Were gonna put a mark at two feet, 24 inches on all the line posts. So our second mark goes at 81. What that is is thats a grade mark, thats the bottom of the fence. So thats going to tell you across the time, whether your fence is going to be high, your fence is going to be right at grade, or your fence is going to go into the ground. - Three inches less than your fabric. - It is three inches less than your fabric. But for your terminal your marks are going to be four inches greater than this. So youre going to have four inches here. Youre gonna mark 28 for your site mark. And then youre going to add four more inches to that 81, which is going to put you at 85. So that being said, were just trying to line up these marks right here with everything that we got behind us but were also paying attention to that mark. On this particular job we have a three-inch max gap that we can be above the ground. So were really trying to stay at about two. Let me make sure everythings all nice and in line before you move on. So right here were going flat all my marks are lining up perfectly. We finally have a grade change. Its not very drastic, but it is still there. And I wanted to show you guys how to handle that with this method. The top of my finger is where the rest of it is the height the rest of that fence is at, but this post is one inch taller. My grade mark is right at ground. So I pulled this post off one inch from that elevation that the rest of the fence is at. So now if we go to this post, thats the distance that Im coming out of the ground. Im lifting the post out of the ground every time to get over this little hump. My grade mark is right still at ground. So all Im trying to do is Im trying to roll over this hump and then go back down, but also roll with style. Maybe you say roll style, make it look good you know. Yeah see me rolling. Yeah I dont know the rest of that song. We build somewhere over 100 miles of chain link fence every year, and on todays commercial chain link job we show you how to set your posts quickly and easily, while finishing straight as an arrow with a nice gentle flow.Contents: 00:00 - Intro 00:48 - Sighting Posts 03:49 - Concrete 08:14 - Setting Height HowToBuildChainLinkFence,
