The Mighty Bay Bridge?

The New Bay BridgeAnother rod fails testing

by Brian Leubitz

When you spend $6.5 billion on something, you expect it to last a few years, even if it is one of the world’s widest bridges. (That $6B+ price tag also set a Guinness record!)

Caltrans officials downplayed the failure, stressing that 99 percent of the 407 rods that underwent testing passed, and said that the cause will need to be determined by further tests in a materials lab. But the failure of a second rod leaves the possibility that more rods could eventually fail.

“Hydrogen embrittlement and corrosion occurs over time,” said Steve Heminger, executive director of the Metropolitan Transportation Commission and one of three people on a committee overseeing the east span construction. “They could last 20 years or 50 years, but with this bridge, we want 150 years.” …

“This bridge is safe, and it’s going to perform well in a major seismic event,” he said. “The engineers are saying it’s terrific.”

Some independent experts are not convinced, however.

“That would suggest it did not strip, but that it fractured,” said Bernard Cuzzillo, a Berkeley mechanical engineer. “Because a fracture results in a sudden release of elastic energy, which causes a pop or a bang sound. Stripping is a slower failure and typically does not result in an audible sound.” (SF Gate)

Tollpayers will now be paying for a few million dollars worth of additional testing to give us all confidence, but doubt abounds. The rods are intended to grant additional stability during a seismic event, so perhaps it is natural that even one failure brings about a little nervousness in drivers using the bridge.

But the one certainty we have with the new eastern span is that this won’t be the last we hear about corrosion and botched grouting.  

Gov. Brown Talks Drought and Bay Bridge

Governor looks to maintain cautious approach

by Brian Leubitz

Carla Marinucci of the San Francisco Chronicle has a way with a video camera like few else. She readily acknowledges the less than high tech camera work, even going so far as to name her video series “Shaky Hand Productions.” But she has a way of being in the right place at the right time to ask some very pertinent questions.

Yesterday she posted another such video, this time a dimly lit interview of Gov. Brown. He covered the drought and the frustrating Bay Bridge situation. On mandatory water restrictions he hewed his refrain of letting local governments ride lead:

I like to focus attention and responsibility on local government, local school districts, whenever possible. So I certainly encourage every local community to do exactly what they need … and when it becomes necessary for the state to take over and actually order (rationing) … I’ll certainly do that. “

Cruise on over to her blog post to get the full transcript. Looks like he’ll officially kick his campaign off soon.

End of Session Marathon brings big progress

Last minute legislation is pouring through both chambers

by Brian Leubitz

Session is technically scheduled to start at close of business tomorrow. However, with Yom Kippur starting tomorrow at sunset, legislative leaders are hoping to close up shop tonight. There are a number key piece of legislation in play today. Here are a few highlights:

  • Gun safety – You can find a quick summary of the gun safety legislation in this WaPo article. Forgive the journalist his folly saying that the legislators could face political blowback. Apparently he thinks that the politics in Colorado is somehow a reasonable analog for California. It is not. However, here are a few highlights from the “LIFE ACT” (PDF):

    • require gun owners to report stolen guns within a week
    • further limits who can own a gun, and requires gun owners lock up their guns around people who aren’t eligible
    • limits assault rifles: semi-automatic magazines limited to ten rounds, increases registration requirements
  • Minimum wageLuis Alejo’s AB10 to increase the minimum wage to $10 by 2016 has the support of both legislative leaders and the Governor.
  • Domestic workersAsm. Tom Ammiano’s AB 241 domestic workers bill of rights would provide all domestic workers who care for California’s homes and families with some of the basic labor protections they have been denied for decades. The Senate passed it yesterday, but the Governor has not said anything about the bill. Which way he will go is unclear.
  • CEQA – It looks like at least some reform will get done. Sen. Steinberg’s SB 743 doesn’t completely overhaul the system, but it does ease restrictions on infill projects, especially ones close to public transit.
  • Bay Bridge – The Legislature passed a resolution to rename the Bay Bridge in honor of Willie Brown. The governor opposed it, on the basis that our names for the bridges are good enough as they are. However, as it is a resolution, the Governor doesn’t have a veto.

As somebody who uses the Bay Bridge frequently, I tend to agree with the Governor on this last one. It isn’t a new road, the name has been the same for the better part of three generations. While Willie Brown is certainly a legend to the state and the region, I liked the name Bay Bridge. I have to imagine that the old name won’t go away quickly.

There will surely be more to come as the legislative session wraps up this evening; I’ll try to update with anything major.

Our New $6.4B Bridge

Bay Bridge opens early, pleases crowds

by Brian Leubitz

By yesterday afternoon, my Facebook feed was dominated by questions of when the Bay Bridge would reopen. And when it finally did, around 10pm last night, it was full of videos showing the new span as cars started rolling on.

At 10:15 p.m. Monday, Caltrans and the California Highway Patrol took down barricades at on-ramps and interchanges and let traffic flow to the bridge for the first time since Wednesday night, when it was closed to allow construction crews to make the transition from the old east span to the $6.4 billion new span.

The bridge had been scheduled to open at 5 a.m. Tuesday. But construction went smoothly, and Caltrans Director Malcolm Dougherty announced at the dedication ceremony that it would open Monday night. (SF Chronicle)

It has been about 24 years since the 1989 Loma Prieta earthquake that pushed the need for this new structure, and the design process took much of that time. Since the actual structure has gone up, the work has been fairly quick. While delays were expected because of faulty bolts, some on-the-fly engineering work was able to speed the process up. The fact remains that even with the awkward “shims” supporting the questionable bolts, the new bridge is still safer than most of the other major bridges in the nation.

From a broader perspective, it is truly a beautiful structure. The massive tower stands as a signal that we can still accomplish big things as a state.

Looking for Answers on Bay Bridge Delays

by Brian Leubitz

The bad bolts on the Bay Bridge now mean that the post Labor Day kickoff will be delayed for weeks, perhaps months:

The Bay Bridge’s broken bolts have busted the schedule, forcing the construction team to postpone for weeks or months the opening of the Bay Area’s new signature bridge while critics lambast the builders for missteps that contributed to the delay.

Citing a longer than expected timetable to retrofit the seismic stabilizers where key anchor rods snapped in March, the span will not open to traffic immediately the morning after Labor Day as planned. No new opening date has been set. (Lisa Vorderbrueggen / BANG)

Bay Area legislators are understandably quite miffed. The current eastern span of the bridge is seismically unstable, and will likely come crashing down in a rather devastating fashion if we have any sort of major earthquake. It certainly would have been nice to see that sort of risk eliminated as soon as possible, however, to ensure the longterm stability of the bridge, the delay probably makes sense. The new span is supposed to last 150 years, and cost untold billions to get this far. It would be almost silly to get anxious over a few months at this point.

However, that being said, the money is real, and the delays are real. And all should have been avoidable.

“Heads should roll,” said Senate Transportation Committee Chairman Mark DeSaulnier, D-“Concord. “It’s unconscionable that people have been exposed to so much risk of an earthquake on the old the bridge and paid so much for the new one. People need to be held accountable on these big projects.”

A new report highlighted some of the failures that kept piling upon each other to bring about the delay, but as Sen. DeSaulnier remarked, there is a little desire to find somebody to blame for the mess.

The “Stuff” That Happens

Governor remarks about construction failures that “shit happens”

by Brian Leubitz

The new eastern span of the Bay Bridge has been a long time in coming. It’s been due for replacement since the Loma Prieta earthquake way back in 1989, and since then there has been much discussion about visual aesthetics, “landmark” status, cost and even some chatter about just getting it done. The bridge was set to open in August, but that may get bumped because of some faulty welds. Gov. Brown was waxing philosophical about the issue.

“Don’t know if it’s a setback. I mean, look, shit happens.”

“There are very professional engineers that are looking

at this thing, and when they’re ready to give us their report, I think the public will be satisfied,” he said.

Three dozen cracked bolts — discovered by Caltrans bridge engineers in mid-March — on the new bridge’s single tower suspension span could throw a wrench into those plans. Administration officials may be forced to delay the opening of the new span of the Bay Bridge — in the works since the 1989 Loma Prieta earthquake — depending on the results of a study to be released Wednesday. (Steve Harmon / BANG)

Shit. It Does Happen. However, for the time being Brown, who had a lot to do with the planning as Mayor of Oakland, is looking forward to a big party to go along with the opening. We’ll find out more later today about whether it will go off as smoothly as he would like it.

The Bay Bridge Reopens

I had my bluetooth headphones on as I was at the gym this morning, and I got a text message just before 7am. It’s not really a common occurrence, so I go over and check it out.  And sure enough, it was the alert-sf message announcing that the Bay Bridge had reopened at 7am.  

Cars led by a phalanx of California Highway Patrol officers began crossing less than two hours after the reopening time that Caltrans originally set when it closed the bridge Thursday evening to remove a section of the eastern span and install a temporary detour. And traffic resumed well ahead of the 5 a.m. Wednesday reopening that Caltrans scheduled Monday, after the crack in the steel link, called an eyebar, had been discovered over the weekend.

“Through the night, the crews have worked nonstop – for almost 70 hours – and were able to complete repair work on the damaged eyebar beam,” Caltrans Director Randy Iwasaki said at a hastily called news conference on Yerba Buena Island at 6:10 a.m. “The bridge has been inspected, and it’s safer than it was when we closed it.” (SF Gate 9/8/09)

Sometimes you just luck into something, and that appears to be the case here. Had this inspection taken place some other time, the Bridge would have had to be shut down immediately to be repaired.  The crews were able to make the fix while the detour was being installed, so really, we only lost a few additional hours.

However, given that CalTrans had stated that the Bridge was going to be closed all day, BART is still vastly overcrowded as are the other various bridges across the Bay. Apparently the San Mateo Bridge had extended delays this morning.

Nonetheless, thanks to the CalTrans crews who made the process relatively smooth this weekend.

Ruh-roh: Bay Bridge May Not Reopen on Tuesday

From the not-so-great news category:

Inspectors discovered a crack in a crucial component of the east span of the Bay Bridge on Saturday that could jeopardize the planned Tuesday morning reopening of the bridge. The flaw was found in a chainlike steel link that helps hold up the eastern portion of the bridge. The link is almost 2 inches thick and was cracked halfway through, said Ken Brown, senior bridge engineer.

“The crack is significant enough to have closed the bridge on its own,” Caltrans spokesman Bart Ney announced at a news briefing late Saturday night. “We have to make this repair before we reopen the bridge.” (SF Chronicle 9/6/09)

We should hear more about the details of the repairs today and into tomorrow.  If it’s not open, there will be some very upset commuters Tuesday morning as thousands of people count on the Bay Bridge to get where they need to be. While it’s better safe than sorry, the local economy sure didn’t need extra inconveniences.

26 Hours???

While San Francisco Mayor Gavin Newsom stepped up, others ducked. The lapse of time between the Cosco Busan oil spill being declared a “42 gallon spill” and a “58,000 gallon spill” isn’t the only timeline scandal. I was at the joint command press conference later in the day where the fact it took 26 hours from the time of the collision until the Captain was tested for alcohol kept coming up. The snickers from the press (which included 18 TV cameras) made it clear that “he had left the ship” was an answer that begs many, many questions.

The press conference was at Fort Mason, following it I walked the two mile stretch of the Embarcadero down to where I took the first shots of it hitting SF yesterday. Everywhere, you could see it in the water. Accountability time.

Ship Hits Bay Bridge: Oil Hits SF Shores

Updated with more pics

So after hearing the news that a container ship ran into the Bay Bridge, I figured I’d go see if there was any visible damage. So on the way home from a meeting, I walked out Pier 7 in San Francisco. I was shocked at what I saw when I looked over the sides of the pier. Here are exclusive photos (sorry about quality, shot from my iPhone).

The story linked above said:

Coast Guard officials said fuel leaked from the gash at the port side of the bow for about half an hour before the Cosco Busan’s crew managed to close off the damaged tank and transfer fuel to another part of the ship.

Rob Roberts, a lieutenant with the state Department of Fish and Game, said the 140 gallons of fuel that spilled from the ship will take about a month to clean up. By midday, some fuel had already reached Pier One in San Francisco.

He said the spill is “something we’re worried about. . . . One hundred-forty gallons is 140 gallons too much.” He said private companies hired by the ship owner will perform the cleanup.
