At 1:34 they are using some sort of slurry on the RCC. Haven't seen that one yet.

Another good dam video from Juan. It's from the 18th but don't remember seeing it back then.

Looks like they still have a boatload of work to do. I expected them to be a lot further along by now.
Going to be interesting to see how well the RCC in the middle section holds up it they have to do the kind of flows they did earlier this year. |

Quote HistoryQuoted:
Can they get this finished before Winter? Not sure how the roads across the canyon will fare once the rain starts. Seems to me that their stability would be in question as the areas upstream of the roads fill with water and begin to undercut them. Perhaps others will bring up those questions at the meeting tomorrow. That is after the more "enlightened" reporters ask about environmental impact! 
But it's still an incredibly complex logistics project that they seem to be tackling quite well. |

I'm rather more worried about the greening area on the damn's face than anything going on with the spillway construction. I mean - sure - right now it's not a hazard with the water levels being what they currently are, but when the water level gets back to the spillway height?.... All it takes is one little leak in the right place & this whole thing can still go down...

Wonder what would happen if they had to use the emergency spillway with that road still there? Road quickly washed away then no big deal? Funnel water towards spillway destroying it? In Juan's video they have outflow of 6k with only an inflow of 1k. So they are still drawing the reservoir down. Question I have is what is their level goal for the reservoir going into the winter. |

I can't believe I have been following this situation for over 6 months and I don't even live in California or nearby. I think I have read nearly every page and watched most videos, especially from those from Juan Browne. Hope their efforts are successful.

Is this spillway and different from the last one? I think they should have built a gigantic glory hole instead so the water is always equalized to the bottom river below. |

Quote HistoryQuoted:
http://i.imgur.com/SPXfGnb.jpg So maybe it's just me.. and not discounting the UBER reinforced rebar structures (brings back memories of my construction days) they are using, but one would think it would make sense to BLAST as much as possible prior to rebuilding the lower end of the dam. You could reinforce concrete with ACT OF GOD rebar but the concussive nature of blasting around the existing, already stressed structures probably isn't a great idea. I guess they are the ex-sperts and what not. With the greening on the other side this can't be a good idea? Looks like a small charge given the debris but still. I'd also think they'd have several stout wooden ramps by now so the equipment could sit on the spillway slope and be level, as well as the break tents. I'd be all messed up on balance after spending a long day on a 15° slope being 'new level'.

The CAT stickers will just say XXXX CAT on them and some will say CAT RENTAL but not all, even in my area we have delt with huge national companies and for some its cheaper and easier to rent the equipment local then it is to haul it across the country to a jobsite. there are a few things at the damn that have my fingerprints on them 
the contractor is getting equipment from far away as NC. CAT got with them and set up a nice program with them and the dealers nationwide are all helping on it Quote HistoryQuoted:

Are they working 24/7? If they are, then yes. Cat or the contractor would have a certified tech on hand 24/7. Chances are a few actually. I've seen their fuel and lube truck wandering around. Plus the contractor probably has I would guess at least 10-12 mechanics on staff and CAT probably has one guy each shift on hand for electronic diagnostics, parts ordering and more refined things. Where the contractors Mechanics would handle everything else. Also respectfully to komatsu and other equipment manufacturers. CAT rental is the only company in the US that could come up with that amount of iron that fast. If you think the contractor owns all that, there's no way. Not dollar figure wise. But being able to mobilize it that fast. Tampers on excavators have been around forever. Neat attachments. Used a lot in pipeline work. the backup equipment has backups there are a few things at the damn that have my fingerprints on them

I see a cat rental sticker in the pic below right above the numbers. That is what I was talking about. I know we can't remove those stickers or put our logo on until we have purchased the equipment. That is what I meant. Not calling you out either. http://i.imgur.com/9R9nM2Q.jpg it is in a diffrent style from the normal one we stick on a sold outright one but isnt like the regular cat rental ones It gets confusing as fuck sometimes when stuff comes in and it looks like its a sold machine but its a rental most are long term rental units that have that sticker im talking about on them

I suspect the best we're going to get is the stills and video updates. Cameras 3 and 4 cover the area but they are time lapse and only updated every 3 or so days.

Holy crap. So all that had to be rebuilt. It's the full length of new build. How do people miscommunication get confused about blasting that close to new and weakened structures? Ya think someone would have to permit that with signatures up the chain? Ya I can't imagine working sloped all day tying rebar. Clearly safety isn't s concern. |

Ya gotta admit that the Cat support infrastructure is pretty amazing. I'm a backup driver for a neighbor that does nightly parts delivery between stores in New England, every night. If you need a widget anywhere in NE, and the part is on-the-shelf, anywhere in NE or the warehouse in PA, you can have it at 7 am tomorrow. I've even seen a store strip parts off a new machine, for 'instant' service. It's truely amazing what Caterpillar can do for support. All it takes is $$. Lots of $$$. "If you can hold it in one hand, it costs $100. Hold it in 2 hands, cost is $1000, cannot carry it, it's just expensive. And you can have it NOW." |
