" So what's the first thing that you did before starting the deck framing?"

" Well, the first thing is to get the sill down which was a pressure-treated 2 x 6."

" Uh-hmm."

" First, you put the sill seal down to cushion it in-between the concrete."

" The top of the foundation concrete block and the bottom of the sill plate, yeah."

" That's right."

" Once you've perimeted the whole hollow block work, then we'll bolt it down to the anchor bolts."

" Uh-hmm."

" Make sure it's secure and then display it all out."

" Right."

" [unk] 16 on center."

" 16 inches on the center."

" Leave 2 feet on its side."

" Ryley, why is it important to use pressure-treated lumber for the sill? I noticed we don't use it elsewhere."

" It's just a preventative in the event that you might have any dry [unk] or [unk]."

" Yeah."

" It won't happen with the pressure treated side."

" Right. Okay. So the rest of the material here, these beams, what do you call these?-This is called a cross joint."

" The cross joints?"

" Right."

" And they're made out of oriented strand board and laminated plywood. They're essentially just about the equivalent of a 2 x 3."

" Right."

" This is all Doug fir lamination. What are all these little----"

" These are little pop-outs they put in here. So that you can run your wires, your copper pipes."

" So you don't have to drill through them."

" Right."

" For plumbing and rough wiring."

" Right."

" Yeah."

" This keeps the strength on it."

" Now, the strength is the beauty of these guys, right? They are a lot stronger than just regular structural lumber. "

" [unk] 20 feet. You know, it's easy to handle."

" Uh-hmm. So what setters are they on over here?"

" This is 2 feet."

" There are 24-inch setters."

" That's right."

" Yeah."

" [unk] 2 feet, yeah. 24 inches."

" So we've got a saving in terms of the amount of lumber that's going on in here."

" There's not as much lumber. We don't have a grit going down the middle. There's no [unk] columns."

" Which means that the [unk] is not interrupted down below, but we haven't had to spend the money on columns and concrete pad."

" That's Right."

" And the actual girt that would break the [unk]."

" Right. [unk] is the stronger [unk]."

" What about on this part? This is gonna be our great room and the span is actually what? 24 feet?"

" This is 20 feet."

" 20 feet. And you don't have to break this span either? You don't have to have any support in the middle?"

" No, no with these. That's really the beauty of it."

" Okay. Well, let's just fly and get them all in place."

" Okay."

" Got it?"

" Yeah."

" Hold it up."

" Okay. Now, Ryley this is the only part of the deck that's different from everything else here. We're leaving this hole in the frame which is---- What size is it?"

" It is 5 feet in this direction and it goes out 6 feet."

" Okay, so that we could build a concrete block chimney to go all the way through the great room here and a hearth in front of it for wood-burning stove."

" Yeah?"

" Yeah. Now, the thing that is also unusual is that we switched from using this type of material"

" Right."

" to"

" to regular"

" regular"

" camphor and then this."

" Microlam. Reason being we've got the Microlam because we still have the 24-foot spans so we cannot go for a conventional 2 x 12."

" You have the added structural strength in the Microlam, right?"

" That's right and it's a solid piece so that we can get our good nailing on here."

" Exactly. You can take a joist hanger and put it right on there, right?"

" We've got plenty in there."

" Okay, well, let's get these 3 in place and then we're ready for the plywood. "

" Yeah."

" Ryley, this portion of the addition is 16 x 34, right?"

" That's right. Yeah, 16 X 34."

" What's the logic involving how you put down the plywood? "

" Well, in layout, it started from this point over here, so that's where the first sheet will go down so they stack all the sheets in the furthermost corner where they're gonna be working [unk]."

" Okay."

" By the time they get to this corner, the plywood should be all down."

" Alright. So they're all, assuming they're right-handed, they're working."

" They're working from left to right."

" From left to right?"

" That's right."

" Okay."

" Okay. So now, we're starting a second room down to the corner there with half a sheet. Why is that?"

" We're gonna stagger the joints. Every 4 feet, there'll be a joint."

" Now, why is that important?"

" [unk] just adds some strength. You don't wanna have your joint over a joint."

" You don't wanna line up your joints, yeah."

" Absolutely."

" Yeah, okay."

" Now, Ryley I noticed that every sheet of this plywood that goes down has [unk] adhesive on the tops of our joists here."

" Right. Basically, this whole floor is a trust system. It's what they call it and [unk] when the whole thing is down, it's all one laminated trust [unk."

" Uh-hmm."

" And the way that you do this is by using a construction adhesive. It's 3/4--inch tongue and groove plywood. "

" Okay."

" And nail down securely and it's just [unk]."

" So again, it's a continuation of the whole principle of laminating."

" Exactly."

" We're talking about laminated joists. Now, this whole floor system is essentially a laminated trust."

" Right."

" Trust so that you could in theory, you could pick it up in one corner and it wouldn't give."

" [unk]"

" You can actually [unk] out houses that way."

" Alright."

" That's it?"

" That's it."
