00:00:13.230 --> 00:00:14.787 align:middle line:90% So next up we have Mark. 00:00:14.787 --> 00:00:15.620 align:middle line:90% MARK METZNER: Hello. 00:00:15.620 --> 00:00:16.430 align:middle line:90% I've got-- 00:00:16.430 --> 00:00:17.180 align:middle line:90% NICK FRY: Oh yeah. 00:00:17.180 --> 00:00:18.710 align:middle line:90% MARK METZNER: I'm wired. 00:00:18.710 --> 00:00:21.530 align:middle line:90% I need that though. 00:00:21.530 --> 00:00:22.440 align:middle line:90% Good afternoon. 00:00:22.440 --> 00:00:24.440 align:middle line:84% And the last session of the day, so I'll 00:00:24.440 --> 00:00:28.430 align:middle line:84% be quick because everybody wants to get out of here, right? 00:00:28.430 --> 00:00:29.250 align:middle line:90% Pardon me? 00:00:29.250 --> 00:00:30.400 align:middle line:90% AUDIENCE: I have a hook. 00:00:30.400 --> 00:00:31.400 align:middle line:90% MARK METZNER: Excellent. 00:00:31.400 --> 00:00:32.305 align:middle line:90% Please use it. 00:00:32.305 --> 00:00:36.380 align:middle line:90% 00:00:36.380 --> 00:00:38.400 align:middle line:84% I'm going to do a brief overview. 00:00:38.400 --> 00:00:40.220 align:middle line:84% This has been looked at, obviously, 00:00:40.220 --> 00:00:42.750 align:middle line:84% a number of times over the last two days. 00:00:42.750 --> 00:00:48.500 align:middle line:84% But this is a milestone project in the USA any way 00:00:48.500 --> 00:00:50.750 align:middle line:90% you look at it. 00:00:50.750 --> 00:00:53.310 align:middle line:84% Again, it's Eversource Energy, the owner of it. 00:00:53.310 --> 00:00:57.730 align:middle line:84% Single-pipe system, ambient loop, mild distribution, 37 00:00:57.730 --> 00:00:59.880 align:middle line:90% or 38 buildings. 00:00:59.880 --> 00:01:02.312 align:middle line:84% I thought I heard an extra building somehow got attached. 00:01:02.312 --> 00:01:03.770 align:middle line:84% I'm not quite sure how that worked. 00:01:03.770 --> 00:01:05.472 align:middle line:90% That's fine. 00:01:05.472 --> 00:01:07.180 align:middle line:84% There's commercial buildings, and there's 00:01:07.180 --> 00:01:08.570 align:middle line:90% residential buildings. 00:01:08.570 --> 00:01:11.860 align:middle line:84% So your upside there is you've got good diversity. 00:01:11.860 --> 00:01:14.120 align:middle line:90% They're all single-family homes. 00:01:14.120 --> 00:01:16.010 align:middle line:84% A district loop would not have made sense. 00:01:16.010 --> 00:01:18.320 align:middle line:84% So site selection was very important. 00:01:18.320 --> 00:01:22.090 align:middle line:84% It made sense for the residents as well as the system 00:01:22.090 --> 00:01:23.715 align:middle line:90% itself and the owner. 00:01:23.715 --> 00:01:26.950 align:middle line:90% 00:01:26.950 --> 00:01:29.800 align:middle line:84% 90 vertical and angled boreholes. 00:01:29.800 --> 00:01:34.850 align:middle line:84% So I think everyone knows that there was two configurations. 00:01:34.850 --> 00:01:37.690 align:middle line:84% Two borefields were vertical, and then there 00:01:37.690 --> 00:01:41.290 align:middle line:84% was another borefield that's kind of two borefields that 00:01:41.290 --> 00:01:42.170 align:middle line:90% are angled. 00:01:42.170 --> 00:01:45.070 align:middle line:84% So the verticals were 600 feet in depth, 00:01:45.070 --> 00:01:50.950 align:middle line:84% and the angles were 720 feet, approximately, with quad loops. 00:01:50.950 --> 00:01:57.220 align:middle line:84% Quad loops, what I mean is two U-bends in each borehole. 00:01:57.220 --> 00:02:00.250 align:middle line:84% What I thought was very interesting, and looking 00:02:00.250 --> 00:02:03.080 align:middle line:84% at what was I going to be talking about, 00:02:03.080 --> 00:02:08.360 align:middle line:84% is you have some very interesting dynamics at play 00:02:08.360 --> 00:02:11.240 align:middle line:90% here. 00:02:11.240 --> 00:02:13.790 align:middle line:84% It's a unique coming together, if you think about it. 00:02:13.790 --> 00:02:17.600 align:middle line:84% Credit to Zeyneb, HEET, being able to pursue 00:02:17.600 --> 00:02:22.160 align:middle line:84% this over all this time, and convincing a natural gas 00:02:22.160 --> 00:02:27.090 align:middle line:84% utility that theoretically can't sell any gas. 00:02:27.090 --> 00:02:31.250 align:middle line:84% It's kind of an interesting concept when you think about it. 00:02:31.250 --> 00:02:34.220 align:middle line:84% I thought it was just absolutely amazing because it's 00:02:34.220 --> 00:02:36.000 align:middle line:90% a successful project. 00:02:36.000 --> 00:02:40.460 align:middle line:84% And you had two really very disparate entities 00:02:40.460 --> 00:02:41.460 align:middle line:90% coming together. 00:02:41.460 --> 00:02:44.960 align:middle line:84% And what I did want to do is have a bit of an applause 00:02:44.960 --> 00:02:48.470 align:middle line:84% for Zeyneb and her team, because I don't think anyone's really 00:02:48.470 --> 00:02:50.245 align:middle line:90% recognized what they did. 00:02:50.245 --> 00:02:50.995 align:middle line:90% It was incredible. 00:02:50.995 --> 00:02:54.456 align:middle line:90% [APPLAUSE] 00:02:54.456 --> 00:02:57.440 align:middle line:90% 00:02:57.440 --> 00:02:59.490 align:middle line:84% When you get into some of the weeds-- 00:02:59.490 --> 00:03:01.190 align:middle line:84% and I won't go too far because I know-- 00:03:01.190 --> 00:03:02.940 align:middle line:84% How many minutes do I have left? because I 00:03:02.940 --> 00:03:03.930 align:middle line:90% was overtime last time. 00:03:03.930 --> 00:03:04.500 align:middle line:90% I'm good. 00:03:04.500 --> 00:03:05.870 align:middle line:90% All right. 00:03:05.870 --> 00:03:07.350 align:middle line:90% There's a lot that goes into it. 00:03:07.350 --> 00:03:10.890 align:middle line:84% I mean, it's not simply a matter of sketching out a few drawings, 00:03:10.890 --> 00:03:13.850 align:middle line:84% writing up a couple paragraphs, and we're off to the races. 00:03:13.850 --> 00:03:17.040 align:middle line:84% There was over 1,200 pages of detailed design. 00:03:17.040 --> 00:03:19.740 align:middle line:84% It's the nuts and bolts, making it work. 00:03:19.740 --> 00:03:22.470 align:middle line:84% And you got to hammer out the details, 00:03:22.470 --> 00:03:25.550 align:middle line:84% otherwise you have an unsuccessful project. 00:03:25.550 --> 00:03:28.877 align:middle line:84% So approximately 37 detailed drawings. 00:03:28.877 --> 00:03:30.710 align:middle line:84% I looked at it again, and it's actually more 00:03:30.710 --> 00:03:32.690 align:middle line:84% because there are subsets of drawings. 00:03:32.690 --> 00:03:36.440 align:middle line:84% That said, there was about 37 main ones. 00:03:36.440 --> 00:03:38.420 align:middle line:84% You go through the process once you 00:03:38.420 --> 00:03:42.440 align:middle line:84% get into construction of clarification questions 00:03:42.440 --> 00:03:45.060 align:middle line:90% and submissions and approvals. 00:03:45.060 --> 00:03:49.020 align:middle line:84% And it's not a straight path to success. 00:03:49.020 --> 00:03:50.250 align:middle line:90% There's back and forth. 00:03:50.250 --> 00:03:51.800 align:middle line:90% There's going to be-- 00:03:51.800 --> 00:03:52.770 align:middle line:90% let's be really candid. 00:03:52.770 --> 00:03:54.603 align:middle line:84% There's going to be arguments because that's 00:03:54.603 --> 00:03:55.650 align:middle line:90% the nature of the beast. 00:03:55.650 --> 00:03:56.880 align:middle line:90% You should be doing that. 00:03:56.880 --> 00:03:57.930 align:middle line:90% No, I'm doing this. 00:03:57.930 --> 00:04:00.530 align:middle line:84% And sometimes there's not clarity in the written 00:04:00.530 --> 00:04:01.350 align:middle line:90% specification. 00:04:01.350 --> 00:04:03.800 align:middle line:84% As much as you want to do it, you can't take everything 00:04:03.800 --> 00:04:04.830 align:middle line:90% into consideration. 00:04:04.830 --> 00:04:05.785 align:middle line:90% That's kind of life. 00:04:05.785 --> 00:04:08.750 align:middle line:90% 00:04:08.750 --> 00:04:10.250 align:middle line:90% Some of the changes-- 00:04:10.250 --> 00:04:13.910 align:middle line:84% and I was exposed to it during the process. 00:04:13.910 --> 00:04:16.980 align:middle line:84% And again, I'm not trying to beat up here on anything, 00:04:16.980 --> 00:04:18.470 align:middle line:84% and I want everyone just to realize 00:04:18.470 --> 00:04:23.000 align:middle line:84% what some of the challenges were during the process. 00:04:23.000 --> 00:04:26.720 align:middle line:84% So initially, the borefields, the three of them 00:04:26.720 --> 00:04:29.340 align:middle line:84% were all in a vertical configuration. 00:04:29.340 --> 00:04:33.800 align:middle line:84% There was a change made into the angled boreholes in one 00:04:33.800 --> 00:04:35.750 align:middle line:90% of the three bore fields. 00:04:35.750 --> 00:04:41.360 align:middle line:84% That in and of itself causes some issues understanding, 00:04:41.360 --> 00:04:46.820 align:middle line:84% Will the angled borefield with now quad loops, as opposed 00:04:46.820 --> 00:04:51.530 align:middle line:84% to single U-bends, perform to the level required 00:04:51.530 --> 00:04:53.960 align:middle line:84% for the system to operate properly 00:04:53.960 --> 00:04:56.910 align:middle line:84% and support the building loads anticipated? 00:04:56.910 --> 00:04:58.580 align:middle line:84% So you can probably imagine there 00:04:58.580 --> 00:05:00.450 align:middle line:90% was a lot of back and forth. 00:05:00.450 --> 00:05:02.950 align:middle line:84% What's going on with these angled boreholes? 00:05:02.950 --> 00:05:05.300 align:middle line:84% We had to remodel this, remodel that. 00:05:05.300 --> 00:05:08.200 align:middle line:84% It's not simple as, OK, we're just going 00:05:08.200 --> 00:05:09.650 align:middle line:90% to start angling them out. 00:05:09.650 --> 00:05:12.070 align:middle line:90% It doesn't work that way. 00:05:12.070 --> 00:05:15.170 align:middle line:84% Again, the single U-bend versus the quad loop, 00:05:15.170 --> 00:05:17.710 align:middle line:84% you're looking, What is the capacity? 00:05:17.710 --> 00:05:19.070 align:middle line:90% Is there an increase? 00:05:19.070 --> 00:05:22.430 align:middle line:84% And if so, what's the impact on the total system? 00:05:22.430 --> 00:05:24.230 align:middle line:84% Those have all got to be calculated. 00:05:24.230 --> 00:05:27.140 align:middle line:84% And again, this is something that doesn't happen quickly. 00:05:27.140 --> 00:05:28.640 align:middle line:90% There's a lot of back and forth. 00:05:28.640 --> 00:05:32.770 align:middle line:84% There's a whole hierarchy of, I have a question as an engineer-- 00:05:32.770 --> 00:05:35.020 align:middle line:84% I'm not an engineer, but from an engineering firm-- 00:05:35.020 --> 00:05:40.430 align:middle line:84% over to the owner, Eversource, back down to a contractor. 00:05:40.430 --> 00:05:43.510 align:middle line:84% There's a whole system of checks and balances 00:05:43.510 --> 00:05:45.920 align:middle line:84% that's also meaning time consumption. 00:05:45.920 --> 00:05:49.990 align:middle line:90% 00:05:49.990 --> 00:05:52.010 align:middle line:84% An interesting change that happened 00:05:52.010 --> 00:05:56.800 align:middle line:84% is the North America compliant collection vaults. 00:05:56.800 --> 00:05:59.650 align:middle line:84% Does everyone know what I mean by a collection vault, 00:05:59.650 --> 00:06:01.950 align:middle line:90% or am I talking Greek here? 00:06:01.950 --> 00:06:03.960 align:middle line:84% That's where we have a bunch of boreholes 00:06:03.960 --> 00:06:07.260 align:middle line:84% that come into a collection point, 00:06:07.260 --> 00:06:10.380 align:middle line:84% and that box, if you like-- and it's usually made 00:06:10.380 --> 00:06:12.010 align:middle line:90% from high-density polyethylene. 00:06:12.010 --> 00:06:14.260 align:middle line:84% There are concrete boxes as well. 00:06:14.260 --> 00:06:15.490 align:middle line:90% They are subterranean. 00:06:15.490 --> 00:06:16.540 align:middle line:90% They're buried. 00:06:16.540 --> 00:06:19.140 align:middle line:84% And then from there, you have a supply and return 00:06:19.140 --> 00:06:22.020 align:middle line:84% going in over to the pump house in this case. 00:06:22.020 --> 00:06:27.180 align:middle line:84% There was a change made between the North American compliant 00:06:27.180 --> 00:06:32.530 align:middle line:84% vaults and what was put in on the angled borehole vaults, 00:06:32.530 --> 00:06:34.260 align:middle line:90% a European spec. 00:06:34.260 --> 00:06:37.200 align:middle line:84% On the face of it, you go, What's the difference? 00:06:37.200 --> 00:06:38.340 align:middle line:90% There is. 00:06:38.340 --> 00:06:44.260 align:middle line:84% You end up with different pipe sizes between a European spec, 00:06:44.260 --> 00:06:48.270 align:middle line:84% which is a DIN spec, versus a North American spec, which is, 00:06:48.270 --> 00:06:52.830 align:middle line:84% in this particular case, we use IPS, which is Iron Pipe Size. 00:06:52.830 --> 00:06:56.560 align:middle line:84% Getting those two to marry up, sounds easy. 00:06:56.560 --> 00:06:57.280 align:middle line:90% It's not. 00:06:57.280 --> 00:07:02.540 align:middle line:84% And it ends up being a potential area of concern into the future. 00:07:02.540 --> 00:07:06.650 align:middle line:84% The other last point on changes and impact, 00:07:06.650 --> 00:07:10.990 align:middle line:84% those angled boreholes now were going under wetlands. 00:07:10.990 --> 00:07:12.730 align:middle line:90% Before they weren't. 00:07:12.730 --> 00:07:15.160 align:middle line:84% So there's a whole regulatory process 00:07:15.160 --> 00:07:18.680 align:middle line:84% that has to be adhered to, applications, approvals, 00:07:18.680 --> 00:07:19.700 align:middle line:90% et cetera. 00:07:19.700 --> 00:07:23.350 align:middle line:84% So back to what Nickki Bruno was saying yesterday, this started-- 00:07:23.350 --> 00:07:24.920 align:middle line:84% and Zeyn, correct me if I'm wrong-- 00:07:24.920 --> 00:07:28.360 align:middle line:84% 2019 is when things really got moving. 00:07:28.360 --> 00:07:31.450 align:middle line:84% AUDIENCE: The initial proposal was in the fall 2019 00:07:31.450 --> 00:07:33.797 align:middle line:84% to the Department of Public Utility 00:07:33.797 --> 00:07:34.880 align:middle line:90% MARK METZNER: Until today. 00:07:34.880 --> 00:07:37.810 align:middle line:84% So you can imagine one more step that's 00:07:37.810 --> 00:07:41.020 align:middle line:84% going to unfortunately delay things or potentially delay 00:07:41.020 --> 00:07:41.630 align:middle line:90% things. 00:07:41.630 --> 00:07:46.090 align:middle line:84% And that's the whole communication component that's 00:07:46.090 --> 00:07:48.020 align:middle line:90% vital between all parties. 00:07:48.020 --> 00:07:48.950 align:middle line:90% And is it smooth? 00:07:48.950 --> 00:07:50.063 align:middle line:90% Is it confrontational? 00:07:50.063 --> 00:07:52.480 align:middle line:84% These are all things you have to look at when you're doing 00:07:52.480 --> 00:07:53.910 align:middle line:90% a large project like this. 00:07:53.910 --> 00:07:56.890 align:middle line:90% 00:07:56.890 --> 00:07:58.220 align:middle line:90% You've seen the picture. 00:07:58.220 --> 00:08:00.980 align:middle line:84% That's what the angled boreholes look like. 00:08:00.980 --> 00:08:04.890 align:middle line:84% It's a proven technology and makes a whole lot of sense. 00:08:04.890 --> 00:08:09.600 align:middle line:84% You're having a very small footprint up top at surface. 00:08:09.600 --> 00:08:11.900 align:middle line:84% And then those boreholes splay out 00:08:11.900 --> 00:08:14.460 align:middle line:84% and you have the separation between the boreholes, 00:08:14.460 --> 00:08:17.010 align:middle line:84% so you're not having thermal interference between them. 00:08:17.010 --> 00:08:24.240 align:middle line:84% It allows at the surface to have less impact, if you like. 00:08:24.240 --> 00:08:26.000 align:middle line:84% You're not taking up as much room. 00:08:26.000 --> 00:08:29.180 align:middle line:84% In this particular case, the project 00:08:29.180 --> 00:08:33.539 align:middle line:84% didn't have to redo the whole parking lot and repave. 00:08:33.539 --> 00:08:36.500 align:middle line:90% They had a smaller area. 00:08:36.500 --> 00:08:38.940 align:middle line:84% Some of the areas, and they're a little hard to see, 00:08:38.940 --> 00:08:40.726 align:middle line:90% but this is the one-- 00:08:40.726 --> 00:08:42.059 align:middle line:90% I'm just going to point, it out. 00:08:42.059 --> 00:08:43.601 align:middle line:84% And you've probably seen this picture 00:08:43.601 --> 00:08:47.250 align:middle line:90% here, as well as up there. 00:08:47.250 --> 00:08:50.390 align:middle line:84% Those are the European vaults that I was talking about. 00:08:50.390 --> 00:08:57.680 align:middle line:84% They are substantially different from a North American vault. 00:08:57.680 --> 00:09:03.310 align:middle line:84% That's an area of concern moving forward, 00:09:03.310 --> 00:09:06.610 align:middle line:90% I'm going to pick on you, Brock. 00:09:06.610 --> 00:09:11.150 align:middle line:84% Those pipes, your best guess, is it a good idea or a bad idea? 00:09:11.150 --> 00:09:13.030 align:middle line:90% On the left. 00:09:13.030 --> 00:09:13.897 align:middle line:90% As far as-- 00:09:13.897 --> 00:09:15.105 align:middle line:90% AUDIENCE: Sounds like a trap. 00:09:15.105 --> 00:09:17.785 align:middle line:90% MARK METZNER: [LAUGHS] Boing. 00:09:17.785 --> 00:09:21.070 align:middle line:90% 00:09:21.070 --> 00:09:24.580 align:middle line:84% In comparison to a regular vault. 00:09:24.580 --> 00:09:25.250 align:middle line:90% AUDIENCE: Yeah. 00:09:25.250 --> 00:09:27.925 align:middle line:84% It's unconventional for what I'm used to seeing, 00:09:27.925 --> 00:09:29.180 align:middle line:90% just the way it's laid out. 00:09:29.180 --> 00:09:29.470 align:middle line:90% MARK METZNER: Yep. 00:09:29.470 --> 00:09:29.970 align:middle line:90% OK. 00:09:29.970 --> 00:09:31.760 align:middle line:90% And that's the basic consensus. 00:09:31.760 --> 00:09:34.010 align:middle line:84% People looked at this picture and went, wow, 00:09:34.010 --> 00:09:37.820 align:middle line:84% there's some potential concerns down the road. 00:09:37.820 --> 00:09:40.270 align:middle line:84% The picture on the right is where 00:09:40.270 --> 00:09:44.500 align:middle line:84% those boreholes, where you can see them coming up here. 00:09:44.500 --> 00:09:45.850 align:middle line:90% These ones here. 00:09:45.850 --> 00:09:46.880 align:middle line:90% They're all like that. 00:09:46.880 --> 00:09:49.090 align:middle line:90% They get tied together. 00:09:49.090 --> 00:09:51.050 align:middle line:84% The problem with air-- not problem. 00:09:51.050 --> 00:09:52.480 align:middle line:84% The issue, the concern, is if you 00:09:52.480 --> 00:09:55.900 align:middle line:84% look at the pipe on the right, you can see some of those 00:09:55.900 --> 00:09:58.990 align:middle line:90% are basically being compressed. 00:09:58.990 --> 00:10:03.920 align:middle line:84% That shouldn't be happening for a long-term reliability 00:10:03.920 --> 00:10:06.380 align:middle line:84% because ultimately, this gets backfilled, 00:10:06.380 --> 00:10:09.620 align:middle line:84% gets paved, and then you can potentially-- 00:10:09.620 --> 00:10:12.620 align:middle line:84% this is a parking lot-- have big trucks on top 00:10:12.620 --> 00:10:14.100 align:middle line:90% pushing down, pushing down. 00:10:14.100 --> 00:10:17.570 align:middle line:84% So it's an area of concern that, again, 00:10:17.570 --> 00:10:20.960 align:middle line:84% in retrospect, may have been addressed differently. 00:10:20.960 --> 00:10:24.110 align:middle line:90% That's the vault. 00:10:24.110 --> 00:10:26.490 align:middle line:84% They're used in Europe all the time. 00:10:26.490 --> 00:10:28.170 align:middle line:90% There's nothing wrong with them. 00:10:28.170 --> 00:10:30.570 align:middle line:84% They're just not North America compliant. 00:10:30.570 --> 00:10:36.830 align:middle line:84% They have components inside, particularly PCV plastic. 00:10:36.830 --> 00:10:41.270 align:middle line:84% If anyone was here this morning, the standard in North America 00:10:41.270 --> 00:10:46.760 align:middle line:84% says you're not using PVC in these systems, subterranean. 00:10:46.760 --> 00:10:49.940 align:middle line:90% So that's below the wetlands. 00:10:49.940 --> 00:10:56.100 align:middle line:84% It's not a huge issue so long as you get the proper approvals. 00:10:56.100 --> 00:10:59.100 align:middle line:84% The wetlands are an area of concern for everybody. 00:10:59.100 --> 00:11:02.340 align:middle line:84% And you have to make sure you're dotting Is and crossing Ts. 00:11:02.340 --> 00:11:04.990 align:middle line:90% 00:11:04.990 --> 00:11:08.840 align:middle line:90% Again, just the quick takeaways. 00:11:08.840 --> 00:11:10.400 align:middle line:90% Communication is key. 00:11:10.400 --> 00:11:13.510 align:middle line:84% I mean, I know we've heard that repetitively. 00:11:13.510 --> 00:11:14.810 align:middle line:90% It came to the forefront. 00:11:14.810 --> 00:11:17.830 align:middle line:84% And this one in particular, when changes happened. 00:11:17.830 --> 00:11:21.590 align:middle line:84% And they were somewhat unconventional. 00:11:21.590 --> 00:11:22.790 align:middle line:90% We'll leave it at that. 00:11:22.790 --> 00:11:26.020 align:middle line:84% That change from the single U-bend to the double U-bend, 00:11:26.020 --> 00:11:29.180 align:middle line:84% again, adds some complexity to the whole issue. 00:11:29.180 --> 00:11:33.560 align:middle line:84% And from a modeling and performance point of view, 00:11:33.560 --> 00:11:35.660 align:middle line:90% required a lot of redoing. 00:11:35.660 --> 00:11:40.370 align:middle line:84% And then the materials used are not North American compliant. 00:11:40.370 --> 00:11:42.620 align:middle line:90% Not that's the end of the world. 00:11:42.620 --> 00:11:47.590 align:middle line:90% It's just to be recognized. 00:11:47.590 --> 00:11:48.730 align:middle line:90% And that's it. 00:11:48.730 --> 00:11:49.300 align:middle line:90% oh, good. 00:11:49.300 --> 00:11:50.630 align:middle line:90% I didn't go overtime. 00:11:50.630 --> 00:11:51.650 align:middle line:90% I'm zero minutes. 00:11:51.650 --> 00:11:52.250 align:middle line:90% Perfect. 00:11:52.250 --> 00:11:55.900 align:middle line:90% [APPLAUSE] 00:11:55.900 --> 00:12:02.000 align:middle line:90%
