Thank you. I was basically ignored when this project started when I was naieve enough to think I could help optimize obvious errors. And I saw none of the usual cast of characters who would have been involved if it was more feasible (generically they have policy to not waste millions on bids for trouble deals, but they will do owners engineers work, but the mayor opposed anything but design build, which is a major cause of incomplete engineering and change orders). Ansaldo as well. Not top of the line. I keep on saying someone should look into Finmeccanica, it's former parent for good reasons.
