If construction workers are anything like carpenters or other craftsmen this rule might even go to 1:50. Ever had a carpenter fix something in your house? The difference between a good carpenter and a bad one is enormous. A good one comes in and fixes the shit in a day or two. A bad one can delay a small project for months, they don't show up, you can never reach them, the final bill is 5x the quotation, they leave your entire house dirty, they come in, punch a few nails then they have to drive pick something up - on your expense of course. And once it's done it's not better than anything you would have been able to do yourself. Once you find a good carpenter you simply stick to him, attempting to hire a new one is too big of a risk.
