Pilings

Why are these pilings so deep, and why are there like 20 of them? They're just putting in a surface Muni platform, not a 6 story building, right?

    Dunes. Buried burnt rubble. Liquefaction. Very very far away bedrock.

      There's already a street here. For quite some time. With busses and everything.

        That location is the only one, of four, that's above street level. Train's gotta come out somewhere, and it's got to be well supported. (It's also possible that they're hedging their bets and prepping infrastructure in case they decide to re-bury the line at a later date. By putting in deep foundations now, they're less likely to have to shut a new station to bury it.)

          The train comes out of the hole on 4th between Harrison and Bryant. This platform is on 4th at Brannan, at least 600' away. And for years there had been a raised bus stop island there. You can still see it on street view at the moment. Surely the thing they're putting there is not going to be any more involved than the one at King.

          Those pilings are at least 40' deep, and there are seriously like 20 of them, spaced a couple feet apart. How much additional weight could they possibly be adding onto what's there now? It makes no sense.

            I was going to make a joke about American weight gain trends and elephant stampedes, but how about the simpler government waste theory:
            They had X dollars for the platform, they only way to spend X dollars was to massively over-engineer it, and spending too much less than X dollars on this platform would cut the budget for some part of the system that actually needs that much money?

  2. Its the google/twitter/uber private platform below the actual station. It'll have free coffee, massage, and yoga on the hour.

    Too Greedily. Too deep!

    Just as in religion and the infopocalypse, there ought to be four horsemen of graft & corruption. "But think of the children that might be standing there if the big one hits!"

  6. I wondered about this too. Can't ignore the possibility that it's good old corruption.
