Sure looks like the plan is to have simultaneous tunneling in phase 1 and phase 2&3!
I guess that was the only way the whole thing opens before 2024 (that was the quote from Metro CEO last year before LA2024 became LA2028).

I think the TBM should be named Beverly and John as a subtle jab to certain Beverly Hills council member who cynically orchestrated the subway hysteria to gin up election support and end up costing the school district millions of unnecessary (and ultimately pointless) legal fees, which BTW, were paid out of the funds set aside for building improvements for the whole school district.

Well maybe that's a better name for the phase two TBMs that will actually be tunneling under the Beverly Hills high school tennis courts (lost in the kerfluffle was the info that most of the tunneling is under tennis courts !)
Speaking of tunneling , metro will award two separate contracts for phase three of the purple line, one for the tunneling and another for the two station boxes .
Phase two of decking for la Cienega starts this weekend

Has any provision been made for how a transfer station with the Crenshaw line will work? Will any of the station boxes at La Brea, Fairfax, or La Cienega have good options for transfers?

I don't think cruciform transfer stations work very well. Metro explicitly said they weren't building any of the three to accommodate another line ala the gargantuan Vermont station.
I imagine all have something like knockout panels that could be accessed for a subterranean walkway .
So all three are likely to be more like a T with the stations not overlapping, and a union station esque walkway to your transfer point.
Geographically a fairfax station has to be south of Wilshire.
La brea can accommodate either, but a station box north of Wilshire will be cheaper.
San Vicente is probably also north of Wilshire because of hefty community opposition to tearing up their lovely blvd south of Wilshire

La brea is 96% excavated
Wilshire western will have a full week closure (plus weekends so 9days total) which means only five weekend closures. Hopefully it's a test case for phase two and three and similar shorter blended closures can be used.

They've begun laying the sandwich floor of the la brea station.
TBMs are on the ocean right now en route, to arrive later this month.

Metro updated the official calendar with phase three finishing in 2026
Advanced utility relocation for Wilshire westwood starts in March. First major phase 3 construction.
Decking at la Cienega finished last weekend, five weeks ahead of schedule.
The only decking in phase one hat remains is Wilshire western
The la brea station sandwich floor is at stage three of four.
Excavation continues at fairfax.

Fairfax is 40 % excavated, since it is the smallest station box on the line (and la brea I think is the biggest ) it is going significantly faster than la brea.

Interesting! All this time I thought that phase two TBMs 3&4 would launch from La Cienega, and tunnel west to century city. Actually the launch box is being built in century city, and TBMs 3&4 will tunnel east to La Cienega. Piles and decking for the century city launch box should be starting in March or April with decking finished in about three months because it’s just for the launch pit not the full station excavation (smart!), likewise, they anticipate excavation taking about three months as well. This means TBM arrival in Q4 of this year. A bonus to tunneling east from century city is that the first place they tunnel under will be Beverly Hills high school. Meaning they get it done and out of the way and then there is no danger of further lawsuits stopping tunneling which might be a risk if they started from the other direction. Groundbreaking for phase two construction should be relatively soon. media.metro.net/projects_studies/westside/images/sec_2_cmty_mtg_2017_0928.pdf |

Tunneling for Section 2 is scheduled to begin this fall. Amazing! I hope this schedule holds.
Drill baby drill!

Well that’s probably wildly off because tunneling for phase one isn’t scheduled until midway through Q3 this year, and that’s with TBMs arriving at the port within a month. And according to the source they don’t know if phase two will have one or two TBMs (be ridiculous to order only one, in my opinion) and no jet grouting has taken place for the phase two alignment and there are no piles, decking or excavation of Wilshire rodeo yet, but optimistically, maybe we start tunneling phase two in late 2019?

Post by culvercitylocke on Jan 19, 2018 22:07:07 GMT -8
Per the above doc, btw, piles for rodeo in Q3, decking and excavation in Q4, with project wide tunneling in Q1 of 2019, and station structural concrete in Q3 of 2019
Not a total disagreement with the century city documentation since it doesn’t designate a tunnel drive the same way that rodeo documentation does. Rather it designates three quarters for TBM launch which probably means launch pit construction rather than launching of the TBM
But it does look like tunneling for phase two will begin About 15-18 months after phase one tunneling begins.

Why? It looks like the station is just outside the fault zone, just the Century City station is just outside of the previously drawn fault zones. If the Century City station was ok under the last drawings, why wouldn't the Rodeo stop be ok under the updated drawings? |

Actually, looking at the EIR, the station box really starts at Beverly and ends just east of Canon Drive. So the closest portion of the station box to the fault zone is well over 500ft away. Is that not sufficient?

Looks to me like it misses the fault. Nice job Metro!
(Although, I still do wish the station were closer to Rodeo Drive.)

Over last weekend, metro officially broke ground on phase two at century city. First up is constructing the launch box for the TBMs while utility relocation for the century city station continue to the west of the launch box.
Piles and decking for the launch box should be finished by Q4 of this year, with piles and decking for rodeo station starting around the time that the launch box finishes up both.
No word on when the phase one TBMs arrive and when they will be launched from la brea to start the year long tunnel drive east to Wilshire western.

No word on when the phase one TBMs arrive and when they will be launched from la brea to start the year long tunnel drive east to Wilshire western. Supposedly the segment one TBMs have arrived by now. I read somewhere the parts are being stored in Riverside. Also supposedly, the segment two TBMs are supposed to launch in Q4 of this year. (See page 16 of the linked PDF file for the construction schedule.) But according to that schedule, Metro is already far behind schedule. |

According to a comment by Steve hyman at the source, tutor perini has not even yet put in an order for phase two TBMs, so although launch box construcionnis beginning, there’s nothing to launch! Oy.

If the current omnibus spending bill passes congress the TIGER program will see its budget tripled, that is probably great news for the purple line as it makes it much more likely phase three will also get the full funding agreement that phase two got last year

The big news is keeping the Capital Investment Grants ("New Starts") program well-funded. According to page 10 of this document, Metro intends to seek $1.5 billion in New Starts funding for the Sepulveda Pass Corridor and $900 million for the West Santa Ana Branch Corridor: metro.legistar.com/View.ashx?M=F&ID=5505022&GUID=E85D9179-1767-4A84-8BC1-62315A58704F |

I believe metro already has a bid in for phase three with the tIGER program to be the pilot project for new acceleration funding models, this may help that as on the technical metrics, phase three probably can’t be beat but they might not wanted to have allocated such an expensive project for a pilot, now that’s less Of a dealbreaker

Phase three had a community meeting, UCLA station decking and piling in early 2021, with something called end wall piling in 2020 with relocation of a sewer and storm drain in between.
For some reason, they’re suggesting the tunnel drives for phase three will be staggered rather than simultaneous, which makes me suspicious they’re going for the slow and cost wasting single TBM rather than dual TBMs as in phase 1.
The VA hospital station will be an open cut excavation, including, apparently, under cal trans brand new 405 entry/ exit ramps. Tail tracks in a tunnel apparently will extend quite a ways further west.

In the 10 year history of the TIGER program, LA received only 1 TIGER grant for a transit line--in 2010: $20 million for Crenshaw Line. The major funding has been with the Capital Investment Grant/New Starts program. |

They are building the launch cradle at Wilshire la brea for the tbm launch in a few months.
Fairfax station is now 85% excavated.
La cienega station is now 20% excavated.
La brea station is looking really good.
The infinite heinous disruption of jet grouting has moved west of la cienega into Beverly Hills, now they get to deal with that hell for two years
Unfortunate for all of Los Angeles, but tutor perini also won the contract for phase three, the purple line is so screwed.
An unforeseen delay has already occurred for the infamous tutor perini at century city, so an eighteen month road closure of constellation isn’t beginning until August. Since metro so dumbly awarded the contract to them, I expect phase two and phase three to be completed six years late and six billion over budget—each.
But TP is proceeding with demolition for he staging area while school is out for the summer at BHHS, since it is TP I’m surprised they did t screw that up too and get themselves a year delay as a result!
The ace gallery in BH will start demo this month.
