Call the framers rough carpenters and you'll receive a scowl. Framers know nothing happens without them (just like us designers.) The experienced crews always study the weather, and their tarps are within reach.
At 7 AM this morning, the new master bath and sitting area framing began. It's now 2 PM, and the approaching storm is forcing a FEWS (Field Emergency Waterproofing System.)
They'll be dried-in shortly, and ready for work in the AM. And I'll have to inspect all surfaces to prevent tarp billow and water intrusion.
