We knew the fast progress at the beginning was too good to be true.

Major Project Status Report for February 2021 is now available. Completion figures for each section are in line with numble's figures from the December project report: - Section 1: 67% complete.
- Section 2: 41% complete.
- Section 3: 18% complete.
Section 1 is now forecast to be completed in Fall 2024, a full year late. Latest delays are due to soil anomalies encountered while tunneling Reach 3. |

March 2021 Construction Committee updates on the Purple Line.
Purple Line 1: Second tunnel machine expected to reach La Cienega and complete tunneling next week.
Purple Line 2: Both tunnel machines are stopped under Beverly Hills High. One is undergoing scheduled maintenance, but the other has unplanned repairs/maintenance required.
Purple Line 3: Not much to report. Tunneling has started.

An independent monitoring/oversight report says the San Vicente anomalies will likely delay start of service on Purple Line Section 1 to late 2024, and isn’t optimistic that they can find ways to recover the lost time.

Purple Line updates:
Purple Line 1 budget needs to be increased again by $150 million due to the San Vicente anomaly that ate up almost a year of time. And they say the contractor has additional change order claims that Metro is currently disputing so it is currently not part of the budget increase ask.
Purple Line 1 - based on reports, it should be done with tail track mining, so the TBMs should be done.
Purple Line 2 - they report that the damaged cutterhead was repaired on May 1, so it looks like that was a 1-2 month delay.
Purple Line 3 - they report that both TBMs have launched. Since tunneling on Purple Line 2 was delayed so much, there really could be a situation where tunneling for both 2 and 3 end around the same time. Then again, who knows if they encounter even more anomalies...

The Phase 1 anomaly caused tunnelling delay by 3 months if I recall. Why is opening now a full year behind schedule?
And looks like Phase 2 tunneling anomaly didn't cause any delays.

The Phase 1 anomaly caused tunnelling delay by 3 months if I recall. Why is opening now a full year behind schedule? And looks like Phase 2 tunneling anomaly didn't cause any delays. The Phase 1 anomaly was discovered sometime in Spring/Summer of last year, and they didn't get it mitigated until around February or March of this year. Yeah, the Phase 2 anomalies took nearly as long, but it didn't cause a delay in schedule or a large budget increase. They never explained why that was. Maybe because the Beverly Hills school district was responsible for mitigating the anomaly on their school grounds instead of the contractor, they accelerated the Rodeo station excavation by a couple of months, they waited until the anomalies were mitigated before they started tunneling (so fewer tunneling crews sitting around doing nothing), and maybe Tutor Perini is being strategic about this project, as it is their first project since an informal two-decade ban by Metro--they don't want to hurt their chances on winning the next $10 billion in projects (ESFV and WSAB) by having a delay or budget overrun on this $1.4 billion job. |

phase 1 they mention the anomaly and also the Crescent Heights gas and methane issues and I think unknown abandoned wells too there... I think the combination of the anomaly and the intense gas/well issues west of Fairfax delayed teh entire reach three tunneling.
for Phase 2, they were insanely behind building just the TBM pit, it took them like a year to excavate, then a year delay in the tunneling. so that is especially strange.
however, they did gain a year of time with the Rodeo-Covid acceleration last spring, so maybe it balances out?
Additionally, if excavation of Century City station is already 17% complete, then it should be completely excavated with HDPE and invert slab by the time the phase 3 TBMs garrive, so they may not have to do the expensive and extremely long, in-tunnel TBM disassembly they had planned to do.

Tutor already got the larded up with that gold plated LAX station for $900 million so we'll see if Phase 2 starts to slip.

May 2021 status reports:
Section 1: 70.3%. chedule/progress forecast has been updated to account for a 1 year delay.
Section 2: 43.7%. Both tunnels are now moving and made about 3-5% progress in the month.
Section 3: 23.3%. Tunnel machines still in startup phase. UCLA station piling was expected to start next week.

June 2021 status reports.
Section 1: 70.6% (+0.3%)
Section 2: 44.3% (+0.6%)
Section 3: 25.7% (+2.4%)
Purple Line Section 2 has slower than expected progress—they apparently have issues with the conveyor belt systems for tunneling and have decided to replace it with system with another type of system, a crane and muck box system, which requires pausing tunneling.

July 2021 status reports for Purple Line:
Section 1: 71% done, +0.4% since June. Contractor added another month to the estimated completion date (now July 23, 2024).
Section 2: 44.9% done, +0.6% since June. Contractor added 11 days to forecast completion, expects to be 71 days late. They paused to replace their conveyor belt mucking system recently with a different system (the system that removes excavated dirt from the tunnels) and say things will move faster now.
Section 3: 26.9% done, +1.2% since June, but 5.9% behind planned progress.

September 2021 Purple Line status reports:
Section 1: 72%, +0.4%. Estimated completion delayed another 12 days.
Section 2: 46.1%, +0.1%.
Section 3: 29.5%, +1.6%.
Sometimes the progress can be distorted by a large change order (I haven't looked deeply at the reports to see if this is the case). If a project costs $100 and you have completed $50 of work as of August, it is 50% done in August. If you have a $5 change order that makes the project now cost $105, and you've completed $53 of work as of September, now you've only completed 50.5% of the $105 project (but it would've been 53% done without the change order).

Tweets have since been deleted, but this account on twitter (https://twitter.com/IslaF14) alleged yesterday a ton of workplace safety violations occurring on purple line construction in the interest of speeding construction up to be finished by 2028 for the olympics, with the allegation that the OSHA inspector tasked with overseeing the project is corrupt and ignoring the violations. The first tweet is archived here (https://www.trendsmap.com/twitter/tweet/1458661232987103232). Looks like Laura Nelson at the LA times got in touch (https://twitter.com/IslaF14/with_replies) so if it's legit I expect we'll see an LA Times exposé of it sooner or later.

Interesting—Metro has been saying in the monthly meetings and reports that they are not happy with the safety on the Tutor Perini Purple Line projects. |

Last week metro had a virtual Regional Connector community meeting (recording is already available) and they also gave updates for the new Metro Center building and the B/D turnback project. I submitted a question to Metro about online reports that the turnback project had been incorrectly designed to light rail specs and they said that they had never heard that. I’m not sure if it was a project person or a community relations person that presented (guessing the latter) but the video is there and I can check. Hopefully it’s not true because that would be very bad and indicates that there could be very serious PM issues at metro.

November 2021 status report for the Purple Line sections.
Section 1: 73.6%, +0.8%. They have a new target completion date of October 9, 2024, but contractor already is forecasting they are going to miss that by 10 weeks (forecast completion is Dec. 16, 2024).
Section 2: 48%, +0.7%. Tunnels are 42-44% done (+6%). Due to slow tunneling rates, contractor added 108 days to forecast completion. Now expects to be 190 days late (6-7 months late).
Section 3: 32.2%, +0.5%. Both tunneling machines are now starting to tunnel.

Hopefully it’s not true because that would be very bad and indicates that there could be very serious PM issues at metro. Although Metro denied any knowledge that the turnback was designed incorrectly - reportedly light rail specs and not heavy rail - they are now asking the board for an additional $75 million with the number one cause being "multiple design issues". It will be interesting to see if any board member questions what those were. If they were the fault of the contractor, then metro shouldn't authorize extra, but if they were the fault of metro specifying or approving designs that were blatantly off, then that indicates much bigger problems on the metro side. metro.legistar.com/View.ashx?M=F&ID=10524829&GUID=0B3CDDFD-204E-445F-9178-2904F312B96B |

Section 1: 75.1%, +0.9%, trending towards being 10-weeks late on October 2024 completion date (a delay from last report by 2 weeks).
Section 2: 48.77%, +0.3%. Tunneling machines were mostly not tunneling in January as they are being walked through the Wilshire/Rodeo station and being setup for the next push. Estimated completion was delayed another month.
Section 3: 33.64%, +0.8%. Tunnel machines tunneled about 900 feet each in January.
