Glad it helped. I just expanded on other ideas I saw here. I think the excavation and shotcrete crews used it the most, but you organized yours a little better than mine (had to flip up to see the plumbing and other diagrams on mine). I don't know if you have experienced it yet, but those easels are not stable in the wind, so I would suggest something to weigh it down in the wind (I have sandbags for a pop-up canopy that I used with rope to hold it down)
I think I have gone through 5 cases of Gatorade/Powerade (and 1.5 cases of water) from Costco already, so you will probably go through more with more of your work being in the hotter months. We also keep snacks in a separate tub, but they don't seem to go through that as much (especially as it has warmed up). Every crew seems surprised that they are there and have been very appreciative.
I'll PM you, but you probably have the same list as I had. My neighbor down the street had an issue with our electrician (they walked off of her job), but I had a great experience with the same crew just a day or two later (including the idea of the grotto uplight). I ended up only getting one quote for electrical because of a lack of response from the trade, but was happy with the choice. Another member here has had issues getting in touch with the shotcrete company I used, but shotcrete was the hardest trade to get a bid from out here. I'm using the same tile/coping/deck/plaster/turf company as
