I feel that the title is misleading. Caltrans faulted by practicing terrible project management. If someone underbids the next contractor by $250 million on a job they've never done before, you're supposed to politely laugh them out of the room. Edit: for the benefit of those now arriving, the title and link have been changed.

caltrans and california gov ... just way too corrupted

Never attribute to malice that which is adequately explained by stupidity.

I really love the progress bar on the top of the page. I wish more long form articles were like that.

Lucky for you, it's baked in to every modern web browser in existence - just look to the right for a built in progress bar that even lets you click to a particular section of the article based on it's progress.

Unluckily for most mobile viewers (definitely on iOS), scrollbars aren't persistent (makes sense when you have limited real-estate). A sign of the times - mobile and desktop client parity in web readership?

What a fiasco. This story just keeps getting bigger and bigger. So many lessons to be learned about a flawed bidding and construction process. And from what I see, it's immune to politics. No party can take the higher ground. Public sector graft and private sector lying, cheating and thieving, both need to be stopped and big, small government, or running government like a business doesn't seem to help. Instead, worki…

This is exactly the right attitude in my opinion. Wherever there is money to be made, be it public or private sector, thieves will show up with big smiles and sharp suits on. Consequences are the only thing they understand, and prison sentences are the only true consequences for white collar crime (fines just become a cost of doing business, the only thing you can't get back is time).

It seems like the author is trying to make the assertion that all sorts of poor decisions were made - it'd be helpful to have a comparison to other similar projects, in order to make that determination. Otherwise, these could be completely routine issues for all I know (as a layperson). If you took any software engineering project, and described it by detailing all the mistakes in isolation, it would look like a comp…

The weld is really the key difference here. For welds to be structurally sound, and for them to work in the calculations that have been performed for the structural integrity of the structure, they have to meet a certain standard. These welds didn't. The company said that they themselves would state whether those standards were met. So this would be more akin to a computer chip manufacturer, where every Nth chip is f…

Yep. The big reason that the convenient approximations (lies) we use in mechanical and civil engineering work is that it is expected that the implementer of our designs (elaborate lies) doesn't use the wrong parts--there are exhaustive specifications on things as boring as bolts and threads and welds specifically to ensure that the behavior they exhibit is within the realm of what the designer expects.

It's nice to see software engineering practices being backported to more conservative and stagnant forms of engineering. 8)

"As delays dragged on, Caltrans approved paying the contractors an additional $6.5 million to boost efficiency and quality, and to catalog the work."

WTF... I know a lot of us here are contractors. Tell me the last time you got paid MORE because you weren't doing your job.

I know it's hard to resist making snarky comments, but you jumped on it a bit too early, and I'm afraid you missed the point.

My comment was specifically about It's about the fact that the bar is at the top of the page. It's a completely different user experience than the standard scroll bar.

Most of the time, you can't, at least not for government projects. Because of procurement laws and rules (designed, among other things, to allegedly be transparent and to provide accountability), a government body is required to accept the lowest bid from the contractor that met all of the requirements. Seeking an "experienced contractor" is usually seen as code for "we want to use our friends" by a skeptical legislative body, so things like tenure and past projects can't be considered.

And the real kick in the balls:

>As the project wound down, ZPMC reaped tangible rewards, sharing with ABF more than $250 million in cost overruns and incentive payments.

Love the pictures of the bridge. The scale is amazing. Wouldn't it be nice if these were projects we could be proud of?

It is a little hard to understand how serious it all really is. It sounds like inspections were quite rigorous. Past half way down the article, there's two pictures, one of the internals of a box girder, and right below it, a 10mm crack in a tack weld. I mean, the scale differential of the two images is amazing. I can't imagine cracks in the tack welds make a bit of difference in a bridge like that. The bridge looks incredible.

The other reason the traditional scrollbar is useless for gauging progress is one never knows how many pages of comments are at the bottom of the article you're reading. The article could be one page long but have 30 pages of comments and you just don't know until you get to the end.

In this case, sacbee doesn't seem to have any comments at all (good for them!) but I don't read them often enough to have that fact memorized.
