- Prufrock is designed to “porpoise,” meaning it launches directly from the surface, mines underground, and re-emerges upon completion. This allows Prufrock to begin tunneling within 48 hours of arrival onsite and eliminates the need to excavate expensive pits to launch and retrieve the machine.
#Prufrock is designed to tunnel at a speed greater than 1 mile per week, which is 6 times faster than The Boring Company's previous generation TBM (Godot+). This is still 4-5 times slower than a garden snail...but Prufrock is catching up! Prufrock’s medium-term goal is to exceed 1/10 of human walking speed, which is 7 miles per day.
#Gigafactory Texas is an automotive manufacturing facility in Austin, Texas built by Tesla, Inc. A 2,500 acre facility along the Colorado River that produces Model Y and Cybertruck.
From your intro text above "Prufrock is designed to “porpoise,” meaning it launches directly from the surface, mines underground, and re-emerges upon completion. This allows Prufrock to begin tunneling within 48 hours of arrival onsite...". This assembly took 75 days. It was self evident that it could not have been done in under 3-4 weeks.
"Prufrock is designed to tunnel at a speed greater than 1 mile per week". It isn't, this type of EPB would be doing extremely well if it completed 100 ft per day. It can be seen that they only have 10-15 segment sets prepared for installation in the storage yard. As the glues used for the EPDM gaskets and packers need at least 24 hours to dry and cure; It can be assumed that 15 rings per day is their maximum predicted excavation rate, exactly what would be predicted for a TBM if this type.
This type of launch requires umbilical connections for the first 150-200 ft, then a 2 week stoppage for the rest of the backup decks to be installed. Looks like they still have 100ft of umbilical cables and hoses laid out at the entrance. Porpoising is a very limiting application for TBM launching.

Thanks for your additional clarification(s) though. Please continue as necessary -- much appreciated... Quite honestly, it's all very fascinating!
@@AirwaveDynamics Keep the videos coming. I will try to describe what I see. My expectation is another week of work to use up the umbilical then a 2 week stop for the backup installation, then 3 weeks production to complete, 6 weeks from now to completion. A month to disassemble, remove, road bed and open.
@@tunnellingsalisbury7605 I would very much appreciate that. Figured I would continue with the flyovers as long as there's interest. But I'm certainly not an expert on all that is going on at this facility (which appears to be a ton). I know others cover this place and narrate, but that's not really my space. I just hope to provide different perspectives from an aerial point of view. Thanks again my friend!
The stated operation and performance is the ASPIRATION for a MATURE Proofrock syatem. This is early prototype testing. 🤦♂️
How many pieces are in each ring?
I was hoping that you would be the first one to docunent the spoils conveyor system in operation.
Been waiting to see that in operation, every time I see a video it seems they are having a break, like here where several men casually walk out of the tunnel.
I would have thought it's ever boring, in which case the conveyor system would be active, or they would be wheeling concrete segments down the tunnel to install them. I see nether here.
@@paulstubbs7678 This type of TBM cannot excavate and build rings at the same time. There are TBM's that can, this isn't one of them.
In a couple of previous videos you can see the rollers moving, albeit at a snail's pace:

Would be nice if there was a CCTV live view like near some high-rise buildings under construction downtown.
It takes me quite awhile to get in the area, otherwise I'd likely catch more things in action. However, I've got a couple of new ideas I'll implement ASAP.
@@AirwaveDynamics Indeed. I have done this on a few projects (one around this size), they make great time lapse videos. Also did one for a TBM entering a station box, jacking up 2m, walking across the station, lowering 2m, then re-launching at the other end of the station. A great time lapse video.
the boring company - where distance is measured in time
Isn't it meant to be a free training experience? Considering it's a Elon company...
Have you ever considered that possibility? The whole purpose is to train workers for other projects using this free experience
Tesla paying for this? I doubt it. It's an Elon company outside of Tesla helping Tesla out there's a conflict of interest so it's most likely free
@@TheMagicJIZZ a tunnel below the highway will be most efficient
@@TheMagicJIZZ But they did two test tunnels with this TBM set-up in their Bastrop facility. Similar ground conditions. Most TBM contractors don't have the luxury of two test tunnels before taking on a project. This is a commercial arrangement, Tesla and TBC are two different companies with different shareholders despite Musk being a common major shareholder of both. This tunnel appeared to be held up by paperwork (land access for the surcharge soil) and the lack of a key component (the cross discharge conveyor). Now they have started they seem to be progressing at a fairly common rate for a TBM launch.
I expect the VC investors of TBC are paying for this with their $650M investment for 11% of the company. (I wonder how they are viewing that investment so far?)
Its like watching paint dry or grass grow. Everything happens in slo mo.
The guys who dispose of the spoils probably only work part time.
!
Are they drilling today?
Not during any of these clips. Looks like around 10-15 segment sets are prepared for installation in the storage yard. Around 30m (20 rings) of umbilical cables left to keep them going before thy have to stop for a couple of weeks to install the rest of the backup decks.
How tight can it turn how far can they dig and how fast do they go
Turning radius around 125m minimum. Can dig as far as you want (45km is the record I think); fastest ever excavation is around 125m a day but normal good production would be 20-30m in 24 hours. This TBM will have to stop next week for the rest of the backup decks to be installed
please show the estimated egress point
Go to 0:57. Directly across the highway there is a gap in the retaining wall on the perimeter of the building. Somewhere in there the TBM should emerge. Exact location unknown, but there have been some clues in the construction works over the last 18 months that suggest an internal tunnel portal.
@@DessieDoolan Interesting hypothesis...I'm glad you mentioned it. I've been speculating that the opening would emerge inside the new addition still under construction. But figured I'd be chastised for not knowing what the new building is ;-)
To me, it looks like a retail showroom (hence all the glass) ...so that cars coming straight off the assembly line could be sold right there.. Then all other inventory goes through the tunnel, to be parked in the lot, awaiting transport away.. Of course I could be totally wrong.
@@AirwaveDynamics It's speculation, but based on many observations over the last 18 months.
The ducks stated lining up in December, and after going back over notes of where soil testing was carried out, the ducks were suddenly in a straight line.
The alignment is almost exactly east-west (the factory long axis is almost exactly north-south) What isn't clear is where the tunnel portal will be located on that east-west axis.
I'm guessing inside the building by a couple of column bays, then an open ramp to the surface.
@@DessieDoolan Keen observations..
I'm wondering if any and all Boring Co. tunnels will be interconnected in some way. It appears Elon wants to eventually create a whole network of them. Even with this current one being a private Gigafactory route, it would be wise to have 'escape routes' so to speak- emergencies, etc.

@@AirwaveDynamics There was a tunnel proposed for the east of Tesla Road to continue under the river. ‘The Colorado River Connector Tunnel’. That permit has expired, and reading the additional requirements from the City of Austin attached to the permit, suggested the City of Austin wasn't happy with the proposal. May never go ahead.
What might be relevant is that proposal was numbered Aus 6, or similar. I took that to be Austin project 6.
2 tunnels at Bastrop might have been 1 and 2, this one in video above might be no. 3.
Personally, I think this is a one off at this site. Evidence free speculation.
I hope they are secretly tunneling to New Orleans.
This really gives perspective on the challenge ahead for boring company. The idea of super fast boring is hitting against the logistical reality. Look at the mess of conveyors and spoil and tunnel segments etc. and the months to setup and just get started. Hard to see how this ever scales to fast and cheap.
It’s ALWAYS hard for outsiders with limited imagination to see how revolutions can happen.
I figured this is the first proof of concept run with no big rush since customer is Tesla. Wouldn't the speed and efficiency go up a lot on the next run with a normal customer?
@@737smartintrue. But my point is Elon has talked a lot about the speed of the tbm but it looks like there are many other logistics issues that need to be solved to support a high speed tbm. Haven’t heard anything about how to solve the e basic problems like removing spoil.
@@swparsonsbut it's for experience for the workers
Most TBM projects are unique, using bespoke machines, with a crew that comes together for the first time. When there are two drives side by side the second one often goes quicker by 20-30%. No real excuse for TBC to be any different but taking 75 days to set up and start when your website claims 48 hours is not a good advert and the work shown here clearly exposes the 48 hour claim as misleading.

Thanks!
Not sure why you made this video? I don't see anything changing and the machine isn't working
