| 00:00 - 00:03 | The decay detection report arrived yesterday |
| 00:04 - 00:05 | the contractor bought a |
| 00:05 - 00:07 | PiCUS last week and carried out |
| 00:08 - 00:12 | the test themselves, saving us money. The tomogram shows the tree is |
| 00:12 - 00:15 | extensively decayed and cannot be retained. |
| 00:17 - 00:19 | This tomogram is a circle |
| 00:19 - 00:21 | the results will be useless. Take me to see the tree. |
| 00:24 - 00:26 | My Führer |
| 00:27 - 00:28 | The tree… |
| 00:31 - 00:33 | The tree was felled this morning, the contractor |
| 00:34 - 00:36 | recommended immediate removal. |
| 00:53 - 00:58 | Everyone who saw James chambers’ decay detection webinar please leave the room. |
| 01:13 - 01:15 | This tomogram is round! |
| 01:15 - 01:17 | A tree is hardly ever perfectly round? |
| 01:18 - 01:23 | This number of sensors cannot have provided enough detail in the tomogram. |
| 01:25 - 01:28 | Why wouldn’t you question this |
| 01:29 - 01:31 | when the report was received? |
| 01:31 - 01:34 | What is the target level of the tree anyway? |
| 01:34 - 01:37 | I thought it is in the middle of a woodland? |
| 01:37 - 01:40 | What kind of risk assessment was made? |
| 01:40 - 01:42 | My führer there is a desire line |
| 01:42 - 01:46 | A desire line is not a high target, the risk would be low! |
| 01:46 - 01:48 | My führer the desire line leads to a postbox |
| 01:48 - 01:52 | Nobody sends letters, everything is email now!! |
| 01:53 - 01:54 | Nobody used that desire line |
| 01:56 - 01:57 | a risk calculation was not carried out. |
| 01:57 - 02:00 | The report makes no assessment of |
| 02:00 - 02:03 | the target level. It simply identifies low velocities |
| 02:04 - 02:08 | and recommends immediate removal. |
| 02:08 - 02:13 | The report doesn’t include basic information, like the height of the test |
| 02:14 - 02:16 | and doesn’t explain any of the colours in the |
| 02:17 - 02:21 | tomogram. It doesn’t mention any limitations of the equipment |
| 02:27 - 02:29 | Things like cracks appearing as decay |
| 02:30 - 02:34 | or the issues of the different types of decay |
| 02:34 - 02:36 | like soft rot and brown rot being more difficult to detect |
| 02:41 - 02:42 | Or that sometimes the level |
| 02:43 - 02:47 | of decay can be exaggerated around the circumference of the tree |
| 02:48 - 02:53 | and even that occasionally trees can be filled with concrete or bricks |
| 02:54 - 02:56 | Which all obstruct sound waves . |
| 02:56 - 02:59 | All of this must be discussed in the report. |
| 03:00 - 03:02 | You can’t just rely on a terrible tomogram. |
| 03:04 - 03:07 | I’m sure they backed up the result with a resistance drill |
| 03:14 - 03:16 | Let me guess, the stump is solid |
| 03:19 - 03:23 | and a couple of bark inclusions obstructed the soundwaves |
| 03:25 - 03:26 | giving the appearance of decay |
| 03:31 - 03:33 | of course, it’s a robinia after all. |
| 03:40 - 03:46 | Everyone knows they are full of inclusions. It should have been a simple consideration |
| 03:46 - 03:49 | the tomogram was obviously unreliable. |
| 03:53 - 03:56 | The trees blood is on your hands. |
