Water Intrusion During Construction
I’m building a 12′ x 16′ backyard office and am considering using the method of construction of the foundation/subfloor I read about in this article: https://www.greenbuildingadvisor.com/article/air-sealed-and-on-piers
However, I am wondering about how much of an issue rain would be in the time between finishing the floor, and building a roof etc that can protect against water. For example, it would seem that any amount of water that falls on the flooring could be bad as it would fall down between the subfloor panels and into the joist cavities, with no means of further escape. It seems reasonable enough to cover from water before any walls go up, but I worry about the stage where there is some framing on top, but uncompleted, which may be difficult to seal from water intrusion.
(As a second non-related question about this foundation, I don’t understand why they have a fully boxed out beam system, rather than just 3 beams on the piers… It seems they do almost nothing structurally…)
