Maybe union workers, maybe cheap contractors buying low quality material. Maybe both. It’s all a racket.
City I live in has the worst WORST streets in the nation. A “resurface” lasts about 7 months, then starts to sag and crack. Clearly it’s not just the workers..the paving gunk looks like molasses. Thing is, it doesn’t matter whose fault it is, the contractors and tradesmen are always busy and the taxpayers get soaked. So soaked, the city decided to cut the police force and NOT answer any property crime calls.
SF is a big union town and this project is 100% union builders.
You can be sure they cut the usual corners and skimmed their usual cut off of the top, resulting in substandard materials and labor.
They even have a program to rehabilitate criminals by giving them jobs working on the bridge. Yeah, they aren’t doing the advanced stuff, but that should be a hint that they will hire not the best, but who will be the most “diverse”
Affirmative Action and sub-standard materials on a bridge project. No thanks.
