I am a bricklayer and worked on lots of Halls before the quick builds and over a hundred after they started doing them, for a total of about 127 halls, from 1969 to 2005. (Texas, Missouri, Arkansas, Kansas, Louisiana)
Here's the deal on the money as I understood it.
Bricklayers: If you brought all the equiptment to the project you could let the brothes know that it cost you X amount of dollars to take the equipment off your secular job site and bring it to the project. Then you could estimate wear and tear on things like diamond saw blades, which are quite expensive, up to $300 or more. They could also turn in gas tickets for hauling equipment.
I never asked to be paid, but it seemed fair to me for the local QB to pay for expenses like that.
Cabinets: I knew a Brother in central Texas that owned a cabinet shop and used all of his facilities to build the cabinets, then stain them. I am sure he was paid for his material, transportation costs and maybe some shop time, especially if he had his employees had to do all the cut outs.
You have to understand, if a person is involved ALL the time with the regional in their area, it can get very expensive to donate so much of your time and assets to the QB.
I even went and worked on one a month after I quit the WT.
I don't regret helping the brothers that I still love, but I do regret that the WT benefitted from it.
