" The interesting thing about the construction here is that because we're going to fire proof building and everything is concrete and steel if you're gonna build with -- You got a taste and special precautions let's interrupt Riley over here so we can talk about that but why not. This looks like standard southern yellow pine framing lumber but it's not right -- it's not. And help time that is not what we're used to use and this is a fact is we're -- there's -- here this is this especially Bob fire rating to talk about. It's fired treated lumber right fight him at that point in here is salt and minerals basically and -- inhibits any combustion and it any smoke. Bob so it meets code requirement for apartment buildings and it looks just like ordinary lumber but it's it's pressure treated to achieve that right and -- used in the yellow pine it because it's got that nice opens outlets and seen anything you want to you know -- Right the cell structure of the -- is really really open grave opened her eyes but I was astonished that it's the same kind of treatment that you do when your pressure treated lumber for exterior use existed here you're injecting it with salts and minerals that retard -- I any kind of flame yeah. Now as I understand there's also some other aspects to this fire through these requirements right. That's that's right what we have any area that open. Like this underneath this platform to be considered an open area in more than a hundred square feet so that the act -- essentially has taken it and cut it up into sections that are not. No laws. OK -- like Iraq. Eight by ten feet so that's why well we have these odd shaped. Squares and -- But the key is that none of them can be more than a hundred square feet and all of have to act. Almost like cells fire -- exactly and and what they've done it when I have pots and adapt. It's got 58 fire code on either side of these small -- digits. And it's important okay."

" There will actually happening. Sure because this is kind of the bedrooms base yes."

" Let's interrupt that -- Iraqi from Essex construction. Is this stuff typical to work with anything different about him."

" The sizes vary from Borden board you have to select -- that all the talk -- even. So the dimension of the lumber is a little bit irregular and that of course slows you down somewhat little bit yet I imagine that's part of being the whole process of up. Of pressure treating it to make it -- room right -- but you guys have got everything pre -- announcement. All these joists going latest threat right -- go I -- to -- that denies there's just a little bit we did in order for it to meet evenly. With the rest of the piece here including this written."

" OK now Ryley. I thought that this. Kind of firewall business that separates the selves. I mean business -- be the purpose are you close it up well this actually is a miniature carrying cases that it look at that way and and what were the -- apologizing play. -- blocking between Muslims. That closes the cabinet all right well let's let them get this put together so we start down the plywood which. -- Now that the plywood is all being put down with this panel adhesive yes definitely and nails the one thing about this plywood is that because it's. Treated fire retarded there's no -- group a visit to slop. It would come together soon to what they expect suspect as with stone product code requirement to me and a double layer. -- in -- and its sister can overlap the seams right. Boy that's a lot of work isn't it -- north requirement can -- both players for a big work was getting I was material appears to explore. That -- The T square comes in very handy is that will help you mark off where the joists are located. So that the nailing process -- OK now putting down talent he's ever construction adhesive really between the layers. Really is a good idea is on the floor cannot squeaking in the future right that's right you don't win against what you want to take the squeeze out. I think we're doing here is to make sure we overlap these scenes here such as the reason for the second that puts. And we're also going to pick up that seems on joists OK so there comes down the first sheet. And square up against the chalk line. And work is just beginning."
