I have worked construction in San Francisco, and a former General Contractor.
There is a cost difference between all union projects, and non-union projects.
The costs seem outrageous at first. If I wanted to hire a union local 6 Electican a few years ago the union would charge me $101/hr. for a skilled worker to show up.
Yes--it sounds nutty?
The answer is bypass the union, and go non-union?
When all us said and done, and the project is completed, and the developer gets the bill; the few projects I worked on, the total cost of building was roughly the same?
That doesn't take into account what non-union shops cost society either.
Very few non-union shops provide health care. If they do, it's usually a lousy plan.
Workers get sick, or hurt, and worker's compensation runs out; you have workers looking for government medical care.
My point is I'm pretty sure the mob is not affiliated with unions in San Francisco. (I know that was not your point)
My main point is when the building is completed, and it's time for the developer to sell the shiny new building; the price you pay is exactly the same.
Non-union workers make developers more money. The buyer will not see those savings.
You the buyer will not receive a better deal ever. The market determines the price.
Now--if you are the developer, it's a no brainer--kind of--you want the building built as cheaply as possible. You hire non-union, provide lousy training, but live in a grand mansion. You spit out a few spoiled kids, and they run the money machine. (Big Bill of Bradley electric was apprentice for 5 years. Learned the trade. Turned around and opened a non-union shop. Made millions. Made so much money he could shoot his son in-law, and somehow get out if a long jail sentence. Making a lot of money is nice?)
Many unions now have a no compete clause in their agreement. Unions don't want to pay for your schooling, and have their guys opening up non-union shops. I am pretty sure it's never enforced, or even legal? Wow--I'm just writing too much today. Don't feel that great? I'm finding this opening depressing in a weird way. Sorry about bothering anyone with my issues. I sometimes have no one to talk to.)
O.k, I say "kind of" because with a union run job, it's usually done on time, and done well.
This crazy rant is basically developers are usually the only one's saving money with non-union help.
