Why isn’t water damage from rain a big concern when new homes and buildings are under construction?
In: Engineering
It is quite the concern, but stick framing will only absorb so much water so quickly as it has about 12-15% moisture content already. Things like plywood/OSB have a rating about how long they can stay uncovered or get wet before they become unusable, but that lumber is used well before those dates come. Good contractors will also sweep/blow off the water after rains when building the houses.
