A

New carport design here, okay, let's run through the.

B

A

Cab model house is here: that's the first floor only second floor.

B

What marks this this new design of the carport is that we're using.

A

B

A

13 foot or so they happen to be exactly.

B

Measured 151.

A

Inches so that's uh 144.

B

Is 12, so that's that's 12.75 feet as far.

A

As the height they're two by six, this is all sheet with half-inch exterior.

B

Plywood and that plywood goes all the way to the top first stabilization.

A

So that, as you see the edges here,.

B

They're doubled up with.

A

Two by sixes, so that should be a pretty stiff.

B

Connection stabilizing these two weak points here, but.

A

The linear structure should get this.

B

uh The correct kind of strength for the the.

A

Railing right here, just like on this other side, the railing uh is effectively built of the entire.

B

Tall module, it's four modules here, four modules here, these short ones, these short ones here, are attached to the joists and there's going to be a deck. Three three quarter inch osb with epdm top.

A

So it's actually a usable deck for doing yoga for.

B

Sun, sun sunny yourself up there now what about the rain? So, first of all we're going to cover the interior of.

A

B

Entire carport, so the carport is gonna, put your vehicles or whatever, underneath on top here, you're sunbathing in.

A

Order to cover there's a gap here that rain could get in there. So we'll also see this.

B

Side, the interior of the deck, so that no water gets behind it now this is slightly sloped. If you look from the front exactly.

A

Four inches over the 16 foot length.

B

A

Water runoff now.

B

A

B

A

An interesting one here can we do.

B

A

For the water there's going to be a deck here with epdm.

B

The water runs down until it hits this flashing.

A

Which is sandwiched it's effectively like vinyl.

B

Flat vinyl, that's bent, so it's squeezed between uh the.

A

B

And the framing uh the.

A

Steering framing, but it makes this kind of a block where the water can certainly get in there. If you.

B

Look from the top.

A

Look at it, you can't really see it's under the railing, but there's gaps.

B

There's basically, it's curved.

A

Around so the water can get in there.

B

So what are we doing? Water inside the house? No there's a gutter. uh What we've got.

A

B

A

This gutter, that's actually on the inside because we don't want to penetrate to the outside the outside is all sheathed and the finish.

B

Is black sorry.

A

B

Recording the sheeting.

A

Is well, it looks like this if you look at pictures, the actual final.

B

A

B

A

B

A

Is what the actual final picture looks like? So it's all sheaved, uh the gutter is actually on the inside there and then it's gonna be sent out from underneath here.

B

Where the water is so.

A

That's this mechanism here this should work we'll see.

B

Surrounded by the engineer, but.

A

Otherwise, structurally this.

B

Is also resting on three uh piers.

A

One on an edge here.

B

Another one on the edge and one in the middle with um a beam.

A

Across might be enough to do this four by six beam like we have.

B

Here now uh the.

A

Pier in the middle is gonna have to be 28 inches.

B

Three feet down to the frost line, the ones on the outside, according to the basic.

A

Calculations are 22 inches and we might need a couple of beam. A couple of.

B

Posts here around the door now um what.

A

Else here, so what we're showing here is the the banister is actually doubled up two by six. It might be.

B

That the modules have a.

A

Single two by six, but the whole thing.

B

A

Is is like a top.

B

A

Here on the bottom, we might might have something like a bottom plate which.

B

Is a two by two by.

A

B

A

Heavier it might have to be like a four by six solid. Perhaps I don't know the engineer. Will.

B

A

So that's the effective design of the carport.

B

uh Epdm for water, on top nice, nice relaxation structure, functional underneath very simple, because now we're using these tall modules.

A

As opposed to trying to build up a deck and then another railing like railings are actually hard, so we're trying to simplify it for fast build now. I notice this one last thing here. So what is this? This is blocking. We attach the first sheet of plywood. That's that's at the eight foot mark, so the middle of that will be.

B

Actually, eight feet.

A

B

Like half to a little more than half of.

A

Another sheet up here and I don't get trimmed up so it looks like kind of like in this picture. Okay, so that's the carport.
