And as you walk into the space, 59 00:02:40,800 --> 00:02:43,166 you can see the work that's been done on our buttress wall. 60 00:02:43,233 --> 00:02:46,300 Now, if you recall, it was tied into the existing foundation 61 00:02:46,366 --> 00:02:47,600 right here, poured underneath it. 62 00:02:47,666 --> 00:02:50,200 So they formed it up, poured it. Forms are off. 63 00:02:50,266 --> 00:02:53,133 And now at this point, you can see that, 64 00:02:53,200 --> 00:02:56,400 well, Charlie and his guys, they're ready to start framing. 65 00:02:59,533 --> 00:03:01,166 The old rec room was behind me 66 00:03:01,233 --> 00:03:03,533 at the bottom of a staircase coming down to the lower level. 67 00:03:03,600 --> 00:03:06,266 Charlie, you took those out and I hear the old mechanical room's 68 00:03:06,333 --> 00:03:07,533 not working for you either. 69 00:03:07,600 --> 00:03:09,433 Charlie: Yeah, we were tight for space as it was, 70 00:03:09,500 --> 00:03:10,933 so I needed more mechanical space 71 00:03:11,000 --> 00:03:12,566 because we've added on more square footage. 72 00:03:12,633 --> 00:03:13,700 Kevin: And where are you getting a new space? 73 00:03:13,766 --> 00:03:15,800 Charlie: Right over here. 74 00:03:15,866 --> 00:03:18,366 Well, this is our new mechanical space under the dining room. 75 00:03:18,433 --> 00:03:20,200 Kevin: So a basement that we never had before. 76 00:03:20,266 --> 00:03:21,833 Makes sense. Charlie: No, never had it. 77 00:03:21,900 --> 00:03:24,466 But it's gonna allow us to put our new air-conditioning, 78 00:03:24,533 --> 00:03:27,100 our heating, and even our electrical system down here. 79 00:03:27,166 --> 00:03:29,033 Kevin: Okay. And so now we've got one in the front 80 00:03:29,100 --> 00:03:30,400 and the back. Charlie: Right. 81 00:03:30,466 --> 00:03:32,700 So all of this section will do the existing part 82 00:03:32,766 --> 00:03:34,166 of the house, the whole front section, 83 00:03:34,233 --> 00:03:36,400 and then the back existing mechanical space 84 00:03:36,466 --> 00:03:38,000 will do the entire back section of the house. 85 00:03:38,066 --> 00:03:39,300 Kevin: Nice. Charlie: And this is 86 00:03:39,366 --> 00:03:42,366 how we connected them. Kevin: Oh, my gosh, Charlie. 87 00:03:42,433 --> 00:03:44,566 Charlie: It might look a little excessive, but, you know. 88 00:03:44,633 --> 00:03:46,300 Kevin: You built a tunnel through the house. 89 00:03:46,366 --> 00:03:48,166 Charlie: Tunnel, hallway, whatever you want to call it. 90 00:03:48,233 --> 00:03:50,566 But we had an excavator inside the house. 91 00:03:50,633 --> 00:03:52,733 We were able to reach in, dig it all out. 92 00:03:52,800 --> 00:03:55,633 A lot of hand digging, also. And we cut the foundation 93 00:03:55,700 --> 00:03:58,100 open to connect the two spaces. Kevin: Oh, my gosh. 94 00:03:58,166 --> 00:03:59,633 So you can walk through here. 95 00:03:59,700 --> 00:04:01,500 Charlie: You can walk through here. But all of this in here 96 00:04:01,566 --> 00:04:03,566 is going to allow our two mechanical rooms 97 00:04:03,633 --> 00:04:05,666 to connect to each other, our ductwork, 98 00:04:05,733 --> 00:04:07,766 our electrical, pipes, you name it. 99 00:04:07,833 --> 00:04:09,300 Kevin: All right. Well, you are intrepid. 100 00:04:09,366 --> 00:04:11,966 No small jobs. And, Mark, you're the guy who's got to, 101 00:04:12,033 --> 00:04:13,500 I guess, what, build the sidewall there? 102 00:04:13,566 --> 00:04:14,900 Mark: That's right. We're gonna throw this wall in. 103 00:04:14,966 --> 00:04:17,366 Kevin: So block. Mark: Block. 104 00:04:17,433 --> 00:04:20,000 We do have a lot of concrete guys on-site. Formwork. 105 00:04:20,066 --> 00:04:21,500 Kevin: Why not just pour it while they're here? 106 00:04:21,566 --> 00:04:23,466 Mark: So it would have been easy enough, except for the fact 107 00:04:23,533 --> 00:04:25,100 that if they did use formwork here, 108 00:04:25,166 --> 00:04:27,966 we'd have to dig this grade back even more, 109 00:04:28,033 --> 00:04:30,100 which may become a problem, right. 110 00:04:30,166 --> 00:04:34,300 Kevin: So if you use block, can you make that wall as strong as, 111 00:04:34,366 --> 00:04:36,600 say, like, a poured monolithic wall back there? 112 00:04:36,666 --> 00:04:39,866 Mark: So I can. I'm gonna use a bunch of individual blocks. 113 00:04:39,933 --> 00:04:41,800 As you can see, this is a 12-inch block, 114 00:04:41,866 --> 00:04:44,133 so it gives me a bigger spread than an 8-inch block, 115 00:04:44,200 --> 00:04:46,433 which means more strength. 116 00:04:46,500 --> 00:04:48,833 Kevin: What do you got? You got the backhand slide there? 117 00:04:48,900 --> 00:04:51,366 Mark: The backhand slide. Kevin: Look at you. 118 00:04:51,433 --> 00:04:53,033 Mark: But I'm slinging this more to Kevin 119 00:04:53,100 --> 00:04:56,633 because I want to get that ladder mesh in. 120 00:04:56,700 --> 00:04:58,600 Kevin: And so the ladder mesh, Mark, is doing what? 121 00:04:58,666 --> 00:05:02,033 Are you tying one block left and right to each other or... 122 00:05:02,100 --> 00:05:03,600 Mark: So it ties block together, 123 00:05:03,666 --> 00:05:05,766 but it's also there for lateral pressure. 124 00:05:05,833 --> 00:05:07,366 And the reason I do the mortar first 125 00:05:07,433 --> 00:05:10,400 is because I do want to sink this into the joint. 126 00:05:10,466 --> 00:05:11,666 Kevin: Okay. Mark: Make sure 127 00:05:11,733 --> 00:05:14,333 we get maximum strength. 128 00:05:14,400 --> 00:05:17,166 I'm also gonna do the block. 129 00:05:17,233 --> 00:05:19,200 The head joint is the most important, 130 00:05:19,266 --> 00:05:22,166 only because if you don't have a proper head joint, 131 00:05:22,233 --> 00:05:25,133 you're gonna end up with water infiltration. 132 00:05:30,033 --> 00:05:33,466 And, again, I'm gonna wiggle that into place... 133 00:05:33,533 --> 00:05:36,633 just because I want to make sure it's full -- 134 00:05:36,700 --> 00:05:38,000 the head joint. 135 00:05:38,066 --> 00:05:40,300 Kevin: Full meaning that you've got good contacts? 136 00:05:40,366 --> 00:05:41,400 Mark: That's right. 137 00:05:41,466 --> 00:05:44,366 Kevin: Both sides. Mark: Yeah. 138 00:05:44,433 --> 00:05:46,333 [ Drill whirring ] 139 00:05:48,400 --> 00:05:53,066 Kevin: All right, so hole into our, I guess, what, the footing? 140 00:05:53,133 --> 00:05:54,500 Mark: That's right. So... 141 00:05:54,566 --> 00:05:56,866 again, don't forget -- This is a very beefy footing. 142 00:05:56,933 --> 00:06:00,366 It's at least 20 inches deep. We've got re-rod poured into it, 143 00:06:00,433 --> 00:06:02,300 so we have a nice, strong footing, 144 00:06:02,366 --> 00:06:05,700 and that's why we're able to drill into that concrete. 145 00:06:05,766 --> 00:06:08,666 Kevin: So we've got a connection at the head joints 146 00:06:08,733 --> 00:06:09,866 connecting this block to that block. 147 00:06:09,933 --> 00:06:11,000 Mark: Right. Kevin: You've got 148 00:06:11,066 --> 00:06:13,600 your wire fence... 149 00:06:13,666 --> 00:06:15,066 Mark: The ladder. Kevin: Ladder. Thank you. 150 00:06:15,133 --> 00:06:17,733 Wire ladder sort of spanning those joints this way. 151 00:06:17,800 --> 00:06:19,200 Mark: Right. Kevin: Now you got -- 152 00:06:19,266 --> 00:06:22,700 You got bar coming up vertically. 153 00:06:22,766 --> 00:06:24,200 Mark: Exactly. So this is gonna be 154 00:06:24,266 --> 00:06:27,166 our vertical reinforcement. 155 00:06:27,233 --> 00:06:30,133 And, again, all we do, I make sure I have the right depth. 156 00:06:30,200 --> 00:06:35,533 I do. And now I'm gonna fill this hole with epoxy. 157 00:06:35,600 --> 00:06:36,966 And that's what's gonna lock down 158 00:06:37,033 --> 00:06:39,466 this re-rod into the footing. 159 00:06:39,533 --> 00:06:41,366 Kevin: And an uncooperative tip. 160 00:06:41,433 --> 00:06:43,866 Mark: Yeah, a little bit. 161 00:06:43,933 --> 00:06:48,033 I want to work the re-rod to that epoxy anyway. 162 00:06:48,100 --> 00:06:50,833 So as you can see... 163 00:06:50,900 --> 00:06:52,800 And I'm gonna swish it around a little bit 164 00:06:52,866 --> 00:06:55,200 to get the air bubbles out. 165 00:06:55,266 --> 00:06:56,933 Kevin: And how long do you think that takes to set up? 166 00:06:57,000 --> 00:06:59,533 Mark: Probably 15 minutes. Kevin: Nice. 167 00:06:59,600 --> 00:07:01,233 Mark: But I can already feel it getting -- 168 00:07:01,300 --> 00:07:05,133 I can feel the tension in the rebar against the epoxy, so... 169 00:07:05,200 --> 00:07:08,766 Right there. Yeah, about 15 minutes, I'll be good. 170 00:07:08,833 --> 00:07:10,233 Kevin: So that sets up. 171 00:07:10,300 --> 00:07:12,333 And now that's just sitting in the middle of an empty cell, 172 00:07:12,400 --> 00:07:16,200 so you got to tie rebar to CMU. 173 00:07:16,266 --> 00:07:17,933 Mark: Right. So part of the process 174 00:07:18,000 --> 00:07:19,600 of making this monolithic 175 00:07:19,666 --> 00:07:21,700 is, any cell that you see that's empty, 176 00:07:21,766 --> 00:07:23,833 we're actually gonna grout, just like that. 177 00:07:23,900 --> 00:07:25,666 Kevin: Empty, whether it's got the bar in it or not? 178 00:07:25,733 --> 00:07:27,166 Mark: Whether it has rebar or not, 179 00:07:27,233 --> 00:07:30,166 we're gonna manually put it into each cell. 180 00:07:30,233 --> 00:07:31,866 It's gonna be 5,000 PSI. 181 00:07:31,933 --> 00:07:33,533 So it's gonna be really strong. 182 00:07:33,600 --> 00:07:36,033 So the only thing we're gonna do with this rebar 183 00:07:36,100 --> 00:07:39,200 is, we're gonna make sure we put in other pieces as we go. 184 00:07:39,266 --> 00:07:40,800 But we're also gonna want to tie this 185 00:07:40,866 --> 00:07:42,866 for a 2-foot overlap, so... Kevin: So wire 186 00:07:42,933 --> 00:07:45,000 that together, continue all the way up to full. 187 00:07:45,066 --> 00:07:46,266 Mark: All the way up to full height.

They didn't want any part 238 00:09:29,766 --> 00:09:31,533 of making that beam any larger. Richard: All right. 239 00:09:31,600 --> 00:09:32,600 So what have you got done today? 240 00:09:32,666 --> 00:09:34,300 It looks like quite a bit. 241 00:09:34,366 --> 00:09:35,666 Charlie: Well, that concrete right there 242 00:09:35,733 --> 00:09:36,966 is where our original slab 243 00:09:37,033 --> 00:09:39,000 was with a wood floor on top of it 244 00:09:39,066 --> 00:09:40,600 right through the entire floor. 245 00:09:40,666 --> 00:09:42,000 Richard: No insulation underneath, 246 00:09:42,066 --> 00:09:43,466 wood floor on top of it. 247 00:09:43,533 --> 00:09:45,366 So that slab was, what, R-zero, 248 00:09:45,433 --> 00:09:47,333 and that whole HERS rating thing 249 00:09:47,400 --> 00:09:49,033 sort of invited us to get rid of this 250 00:09:49,100 --> 00:09:51,700 because there's so much brick and so much glass, right? 251 00:09:51,766 --> 00:09:53,366 Charlie: That's right. So this is really gonna be 252 00:09:53,433 --> 00:09:56,633 our starting grade to meet all of our thicknesses that we have. 253 00:09:56,700 --> 00:09:57,800 Richard: Yeah. Charlie: We have 254 00:09:57,866 --> 00:10:00,433 closed-cell foam, concrete slab, 255 00:10:00,500 --> 00:10:03,166 2-inch sleeper system with rigid foam in between. 256 00:10:03,233 --> 00:10:05,333 Richard: Yeah. Charlie: We have subflooring, 257 00:10:05,400 --> 00:10:07,100 radiant heat, and our finished floor. 258 00:10:07,166 --> 00:10:08,800 Richard: And this is great because this closed-cell 259 00:10:08,866 --> 00:10:12,100 will act both as a thermal break and as a moisture barrier 260 00:10:12,166 --> 00:10:14,000 so no moisture comes up through and gets that wood. 261 00:10:14,066 --> 00:10:15,433 Charlie: Nothing's getting through it. 262 00:10:15,500 --> 00:10:18,533 Richard: And now we have to bury ductwork underneath all that. 263 00:10:18,600 --> 00:10:20,933 Charlie: That's right. So we found out our new locations 264 00:10:21,000 --> 00:10:22,900 and we put them all where they have to be. 265 00:10:22,966 --> 00:10:25,400 And we started with excavating a trench 266 00:10:25,466 --> 00:10:27,233 to all the locations for our registers. 267 00:10:27,300 --> 00:10:28,900 And then we sprayed some closed-cell foam. 268 00:10:28,966 --> 00:10:31,866 And it will be our starting base once the ductwork goes on it. 269 00:10:31,933 --> 00:10:33,533 Richard: James Bouchard is helping us again 270 00:10:33,600 --> 00:10:34,933 this year on the HVAC. 271 00:10:35,000 --> 00:10:36,100 James: Hey, Richard.

It has to be dry, 277 00:10:44,466 --> 00:10:45,700 and it has to be insulated to code. 278 00:10:45,766 --> 00:10:47,333 Richard: Okay. So what are you gonna use? 279 00:10:47,400 --> 00:10:48,966 James: So right here, this duct 280 00:10:49,033 --> 00:10:50,400 is what we typically use in a house -- 281 00:10:50,466 --> 00:10:53,533 30-gauge galvanized metal. And as you can see, 282 00:10:53,600 --> 00:10:55,133 the weight of the concrete would just crush this. 283 00:10:55,200 --> 00:10:56,533 Richard: There's no strength at all to that. 284 00:10:56,600 --> 00:10:57,766 You put concrete on that, it'll crush like nothing. 285 00:10:57,833 --> 00:10:59,333 James: Exactly. It'll fall right apart. 286 00:10:59,400 --> 00:11:01,700 This spiral is double the gauge thickness, 287 00:11:01,766 --> 00:11:02,900 and it has this seam right here 288 00:11:02,966 --> 00:11:04,733 that adds to structural integrity. 289 00:11:04,800 --> 00:11:06,166 You could stand on this. It's not gonna crush. 290 00:11:06,233 --> 00:11:07,200 Richard: You could stand on it? 291 00:11:07,266 --> 00:11:08,400 James: It's gonna last a lifetime. 292 00:11:08,466 --> 00:11:09,566 Richard: Could I stand on it? James: Go ahead. 293 00:11:09,633 --> 00:11:10,966 Richard: No, you do it. [ Laughs ] 294 00:11:14,266 --> 00:11:16,133 So that's a big difference. That's gonna last. 295 00:11:16,200 --> 00:11:18,800 Okay. So we know it's gonna be structurally sound, 296 00:11:18,866 --> 00:11:22,100 but we also need to make it dry and insulated. 297 00:11:22,166 --> 00:11:24,233 So let's get started with the install. 298 00:11:24,300 --> 00:11:32,866 ♪♪ 299 00:11:32,933 --> 00:11:41,533 ♪♪ 300 00:11:41,600 --> 00:11:50,133 ♪♪ 301 00:11:50,200 --> 00:11:58,766 ♪♪ 302 00:11:58,833 --> 00:12:07,333 ♪♪ 303 00:12:07,400 --> 00:12:16,000 ♪♪ 304 00:12:16,066 --> 00:12:18,100 So, Charlie, what are you doing?

And then this box? 382 00:15:08,566 --> 00:15:09,700 Jonathan: That is your controller. 383 00:15:09,766 --> 00:15:12,100 That is what tells you when the doors are closed 384 00:15:12,166 --> 00:15:14,333 and the gates are closed so that it can safely operate. 385 00:15:14,400 --> 00:15:16,133 Kevin: So we have a pump, which means we need power. 386 00:15:16,200 --> 00:15:17,633 Where do you guys have to put in for electric? 387 00:15:17,700 --> 00:15:21,300 Jonathan: So you need a 240 circuit fused at 30 amps 388 00:15:21,366 --> 00:15:24,366 and you also need a 120 circuit fused at 15 amps. 389 00:15:24,433 --> 00:15:26,933 Kevin: That's not too bad. Not that uncommon. 390 00:15:27,000 --> 00:15:28,566 All right, well, let's go see what it controls. 391 00:15:28,633 --> 00:15:30,766 Jonathan: Yep. Absolutely. 392 00:15:30,833 --> 00:15:32,466 Kevin: Okay, let's see what we got. 393 00:15:32,533 --> 00:15:34,133 Right here at the entrance. 394 00:15:34,200 --> 00:15:36,166 Makes sense. Jonathan: Elevator right here. 395 00:15:36,233 --> 00:15:38,433 Kevin: And how similar or different is this 396 00:15:38,500 --> 00:15:39,966 to what we're getting in our project? 397 00:15:40,033 --> 00:15:41,633 Jonathan: So the project in Lexington 398 00:15:41,700 --> 00:15:43,300 is a little bit different. 399 00:15:43,366 --> 00:15:46,033 Same mechanical-wise, but the doors are gonna be different. 400 00:15:46,100 --> 00:15:48,500 In Lexington, they're gonna be sliding automatic doors, 401 00:15:48,566 --> 00:15:50,066 where this is a manual swing door 402 00:15:50,133 --> 00:15:51,666 with a manual accordion full gate. 403 00:15:51,733 --> 00:15:53,833 Kevin: Okay. But still an elevator door here? 404 00:15:53,900 --> 00:15:55,566 Kevin: Yes. This is a special elevator door 405 00:15:55,633 --> 00:15:58,400 with a cut-out here for your interlock, 406 00:15:58,466 --> 00:16:00,033 which is what keeps the door closed 407 00:16:00,100 --> 00:16:01,366 when the elevator's not there. Kevin: Yeah. 408 00:16:01,433 --> 00:16:03,133 Jonathan: The frame is also special 409 00:16:03,200 --> 00:16:05,200 because the door has to close within 3/4 410 00:16:05,266 --> 00:16:06,500 of an inch of the edge of the hoistway. 411 00:16:06,566 --> 00:16:07,866 Kevin: Which is right there. 412 00:16:07,933 --> 00:16:09,866 And then you say the accordion door -- 413 00:16:09,933 --> 00:16:11,633 sort of a safety mechanism. Two doors. 414 00:16:11,700 --> 00:16:13,500 Jonathan: Yep. Keeps everyone inside the elevator safe. 415 00:16:13,566 --> 00:16:15,000 Kevin: I've been in a few of these by now, 416 00:16:15,066 --> 00:16:17,433 and I've learned that you can pretty much customize the trim, 417 00:16:17,500 --> 00:16:19,133 pick anything you want. Jonathan: Yes. Yep. 418 00:16:19,200 --> 00:16:21,666 There's different trims for the call stations, 419 00:16:21,733 --> 00:16:23,400 different finishes for the wood. 420 00:16:23,466 --> 00:16:25,066 Kevin: Okay. What I'd really like to see, though, 421 00:16:25,133 --> 00:16:27,033 is the operation, the mechanics, 422 00:16:27,100 --> 00:16:28,800 the chase and all that. Can we have a look at those? 423 00:16:28,866 --> 00:16:31,000 Jonathan: Yeah, absolutely. Let me get set up. 424 00:16:31,066 --> 00:16:32,633 All right, step on in. 425 00:16:32,700 --> 00:16:34,266 Kevin: Okay. Jonathan: We've safely locked 426 00:16:34,333 --> 00:16:35,933 the elevator out here with the ball valve 427 00:16:36,000 --> 00:16:38,233 and the stop switch there. Kevin: Beautiful. 428 00:16:38,300 --> 00:16:39,466 Jonathan: So this is the hoistway 429 00:16:39,533 --> 00:16:41,566 that the elevator rides inside. 430 00:16:41,633 --> 00:16:44,100 So as you can see, it's not much bigger than the elevator. 431 00:16:44,166 --> 00:16:45,466 Kevin: Right. And did you guys build it, 432 00:16:45,533 --> 00:16:46,633 and what's it made out of? Jonathan: No. 433 00:16:46,700 --> 00:16:48,200 So this is a contractor-built hoistway. 434 00:16:48,266 --> 00:16:51,133 They build the -- It's a stick frame with Sheetrock 435 00:16:51,200 --> 00:16:52,433 on top of it for fire rating. 436 00:16:52,500 --> 00:16:54,300 Kevin: Okay. But a concrete floor. 437 00:16:54,366 --> 00:16:55,433 Jonathan: Yes, concrete floor. 438 00:16:55,500 --> 00:16:57,400 So that way, it's a nice, solid foundation 439 00:16:57,466 --> 00:16:58,900 for the elevator. Kevin: Right. 440 00:16:58,966 --> 00:17:00,066 And there's your pit. Jonathan: Yes. 441 00:17:00,133 --> 00:17:01,400 This is your depression. 442 00:17:01,466 --> 00:17:03,700 That way, the elevator can stop flush with this floor. 443 00:17:03,766 --> 00:17:05,400 Kevin: And then, so how is this thing working? 444 00:17:05,466 --> 00:17:06,700 Jonathan: This is your piston here. 445 00:17:06,766 --> 00:17:10,066 It's a roped hydraulic, not a direct hydraulic. 446 00:17:10,133 --> 00:17:12,833 Hydraulic fluid drives this piston up here, 447 00:17:12,900 --> 00:17:14,933 which, in turn, drives the ropes down here. 448 00:17:15,033 --> 00:17:16,766 And you have your traveling cable here, 449 00:17:16,833 --> 00:17:18,400 which is basically the communication 450 00:17:18,466 --> 00:17:19,800 between the controller and the elevator. 451 00:17:19,866 --> 00:17:21,866 Kevin: Traveling because it goes up and down with the box 452 00:17:21,933 --> 00:17:23,166 and the box rides on this? 453 00:17:23,233 --> 00:17:24,766 Jonathan: This is your main rail that the elevator 454 00:17:24,833 --> 00:17:26,300 is gonna ride up and down on. 455 00:17:26,366 --> 00:17:27,333 Kevin: Okay. 456 00:17:27,400 --> 00:17:28,900 Jonathan: This is a fire-rated 2x12. 457 00:17:28,966 --> 00:17:31,666 So that way, you keep your fire rating inside the hoistway. 458 00:17:31,733 --> 00:17:33,933 This here is gonna be your tape selector. 459 00:17:34,000 --> 00:17:35,833 That's what tells the elevator when to slow down, 460 00:17:35,900 --> 00:17:37,366 when to stop, and when to take off. 461 00:17:37,433 --> 00:17:39,133 Kevin: And can we see the mechanics above the cab? 462 00:17:39,200 --> 00:17:41,233 Jonathan: Absolutely. Let's head upstairs. 463 00:17:43,233 --> 00:17:45,866 Kevin: Okay. Mostly to the top right here. 464 00:17:45,933 --> 00:17:47,133 Jonathan: Let's lower this down 465 00:17:47,200 --> 00:17:48,833 so you can see the top of the elevator. 466 00:17:48,900 --> 00:17:51,900 Kevin: Okay. A little elevator technician override there. 467 00:17:51,966 --> 00:17:52,966 Jonathan: Yeah. 468 00:17:53,033 --> 00:17:54,533 Kevin: Boy, it is quiet, isn't it? 469 00:17:54,600 --> 00:17:55,733 Jonathan: Yeah. Kevin: And that's because 470 00:17:55,800 --> 00:17:57,466 it's the hydraulic cable. Jonathan: Yes. Yep. 471 00:17:57,533 --> 00:17:59,333 Kevin: Can you hold it there? Jonathan: Absolutely. 472 00:17:59,400 --> 00:18:00,600 Kevin: So what am I looking at? 473 00:18:00,666 --> 00:18:01,700 Jonathan: So this is your brains 474 00:18:01,766 --> 00:18:03,100 for the top of the elevator. Kevin: Right. 475 00:18:03,166 --> 00:18:04,533 Jonathan: And it communicates to the brains 476 00:18:04,600 --> 00:18:06,233 for the whole elevator and the machine room. 477 00:18:06,300 --> 00:18:08,100 Kevin: Well, surprisingly compact. 478 00:18:08,166 --> 00:18:10,333 And I like the fact that it's as quiet as it is. 479 00:18:10,400 --> 00:18:12,200 That's very nice. Big question is, 480 00:18:12,266 --> 00:18:14,166 what does it cost us to put an elevator in? 481 00:18:14,233 --> 00:18:16,333 Jonathan: Roughly a ballpark number -- about 50 grand. 482 00:18:16,400 --> 00:18:18,466 Kevin: And is that for your elevator work? 483 00:18:18,533 --> 00:18:20,000 Jonathan: That is just for the elevator work. 484 00:18:20,066 --> 00:18:21,366 Kevin: Chaseway construction 485 00:18:21,433 --> 00:18:22,533 is in addition to that? Jonathan: In addition 486 00:18:22,600 --> 00:18:23,733 to all this. Kevin: Well, if it keeps you 487 00:18:23,800 --> 00:18:25,000 in your house, I could see why people 488 00:18:25,066 --> 00:18:26,300 are calling you up and having you do it. 489 00:18:26,366 --> 00:18:27,966 Jonathan: Absolutely. Kevin: I appreciate the tour 490 00:18:28,033 --> 00:18:29,566 and we look forward to seeing you in Lexington. 491 00:18:29,633 --> 00:18:30,600 Jonathan: Yeah, I'll see you soon. 492 00:18:30,666 --> 00:18:31,966 Kevin: Thanks, Jonathan. Bring her up. 493 00:18:32,033 --> 00:18:33,333 Let's take a ride. 494 00:18:33,400 --> 00:18:42,766 ♪♪ 495 00:18:42,833 --> 00:18:52,233 ♪♪ 496 00:18:52,300 --> 00:19:01,633 ♪♪ 497 00:19:01,700 --> 00:19:04,733 Tommy, I just laid eyes on our new elevator. 498 00:19:04,800 --> 00:19:06,233 Really nice box. Tom: Yeah. 499 00:19:06,300 --> 00:19:08,266 Kevin: I love it. And you know what I like, too? 500 00:19:08,333 --> 00:19:10,533 Unlike that one, this is not gonna be an addition 501 00:19:10,600 --> 00:19:12,100 on the outside of the house. We get to put it right 502 00:19:12,166 --> 00:19:13,300 in the middle of the house. Tom: Yeah. 503 00:19:13,366 --> 00:19:15,033 Nice, centrally located. It's really great. 504 00:19:15,100 --> 00:19:16,433 Kevin: Of course, you've got to frame out for it. 505 00:19:16,500 --> 00:19:18,400 Tom: Yeah, well, you definitely have to frame out for it. 506 00:19:18,466 --> 00:19:21,033 Think about these floor joists right here that are cut off. 507 00:19:21,100 --> 00:19:23,833 They ran all the way across here and they were rested 508 00:19:23,900 --> 00:19:25,966 on the old wall that was here. Kevin: Yeah. 509 00:19:26,033 --> 00:19:28,233 Tom: All right? So once we cut those away, 510 00:19:28,300 --> 00:19:29,766 they have to be supported. 511 00:19:29,833 --> 00:19:31,700 Kevin: And by supporting them, you mean transfer the weight 512 00:19:31,766 --> 00:19:33,100 that's on them to somewhere else? 513 00:19:33,166 --> 00:19:35,500 Tom: Transfer it out, just like a header over a window. 514 00:19:35,566 --> 00:19:36,666 Kevin: That's why you got a double here. 515 00:19:36,733 --> 00:19:38,300 Tom: We got a double here. 516 00:19:38,366 --> 00:19:40,166 All right, so this is a double floor joist 517 00:19:40,233 --> 00:19:42,533 that a double header will go into. 518 00:19:42,600 --> 00:19:45,333 But if you look at this side over here, 519 00:19:45,400 --> 00:19:48,433 there's actually four engineered LVLs 520 00:19:48,500 --> 00:19:50,033 and a filler strip right here. 521 00:19:50,100 --> 00:19:51,266 Kevin: Why more on that side? 522 00:19:51,333 --> 00:19:54,100 Tom: Well, this wall over here -- or this beam 523 00:19:54,166 --> 00:19:56,800 is gonna be asked to carry a lot more load. 524 00:19:56,866 --> 00:19:59,666 Above that is just a wall that runs up. 525 00:19:59,733 --> 00:20:01,500 This wall is gonna run up 526 00:20:01,566 --> 00:20:05,866 to carry a roof that's going to be angled up over that wall, 527 00:20:05,933 --> 00:20:08,333 but over to the other side of the building. 528 00:20:08,400 --> 00:20:09,933 Kevin: So carrying floor and roof system? 529 00:20:10,000 --> 00:20:11,266 Tom: Floor and roof. Kevin: Gotcha. 530 00:20:11,333 --> 00:20:12,333 Tom: And so now we have to take 531 00:20:12,400 --> 00:20:13,966 half of this load right here 532 00:20:14,033 --> 00:20:16,200 and transfer it to that one and that one. 533 00:20:16,266 --> 00:20:17,233 Kevin: So you got a double here. 534 00:20:17,300 --> 00:20:18,900 Do you put a double up on this opening? 535 00:20:18,966 --> 00:20:20,333 Tom: Yep, a double opening. 536 00:20:20,400 --> 00:20:22,433 Usually an opening that is wider than, 537 00:20:22,500 --> 00:20:24,800 let's say, 40 inches... 538 00:20:24,866 --> 00:20:27,666 usually everything is doubled. Kevin: Okay. 539 00:20:27,733 --> 00:20:29,066 So I'm looking at this framing 540 00:20:29,133 --> 00:20:31,333 and I'm thinking, "Okay, if this was an opening for, 541 00:20:31,400 --> 00:20:34,166 say, a staircase or whatever, it seems sufficient." 542 00:20:34,233 --> 00:20:36,600 But the elevator I just saw, that's a big beast. 543 00:20:36,666 --> 00:20:38,133 This does not look like it's sufficient 544 00:20:38,200 --> 00:20:39,866 to carry an elevator, as well. 545 00:20:39,933 --> 00:20:42,400 Tom: Well, this isn't really carrying the elevator. 546 00:20:42,466 --> 00:20:44,833 It's helping hold the elevator. Kevin: Right. 547 00:20:44,900 --> 00:20:46,666 Tom: But a lot of the weight is transferred down 548 00:20:46,733 --> 00:20:48,900 to the concrete floor. Kevin: Ah. Gotcha. 549 00:20:48,966 --> 00:20:50,333 I mean, we have to have strongbacks 550 00:20:50,400 --> 00:20:51,600 built in this wall here 551 00:20:51,666 --> 00:20:53,733 so the elevator will bolt against it. 552 00:20:53,800 --> 00:20:55,566 But all of the transferred weight 553 00:20:55,633 --> 00:20:57,400 will be down to the floor. Kevin: Good point. Right. 554 00:20:57,466 --> 00:20:59,500 So that's pressing on the pad that was already poured for us. 555 00:20:59,566 --> 00:21:00,666 Tom: Right. Right. Kevin: Okay. You ready 556 00:21:00,733 --> 00:21:02,166 to get these in? Tom: I am. 557 00:21:02,233 --> 00:21:03,633 Let me nail this one off first. 558 00:21:03,700 --> 00:21:05,333 Kevin: All right. 559 00:21:20,766 --> 00:21:24,000 Kevin: All right. The first one in. Here's the second one. 560 00:21:26,200 --> 00:21:27,800 Tom: Get that. Make sure it doesn't fall on you. 561 00:21:27,866 --> 00:21:30,900 Kevin: Aww. You care. Tom: Huh? 562 00:21:30,966 --> 00:21:33,000 Kevin: Boy, that doesn't look close at all. 563 00:21:33,066 --> 00:21:34,833 There you go. 564 00:21:51,166 --> 00:21:53,233 There you go. All right.
