Trade partners who work outside all day
The second buyer your site names, and the crews most exposed to the heat. Foundation, structure and exterior trades are 7,933 establishments, with 890 carrying 20 or more people: roofing at 2,442, poured concrete at 1,858, and masonry, framing, structural steel and glazing behind them. Site preparation adds 2,794 more, 503 of them with 20 or more. A trade partner buys for its own crew, so the pod follows the crew from one general contractor's site to the next.
Who decides: in most of this row the owner, because 7,043 of the 7,933 have fewer than 20 people. At the larger concrete, steel and site work firms, an operations manager or a safety manager.
