To start with they need to take his nail gun license away! If he had to hammer all those nails to make that mess he wouldn’t be so inclined to do so.
Next he needs to go to geometry class and learn what a compound angle is.
Then he needs to go to carpentry school and learn how to operate a framing square.
Mr. Dean, I got your email.
Please send me the address by email and the builders name. Before I go any further I want to check his license credentials at the State. It may be too hazardous to even walk into that house to Inspect it!
There is no terminology in the building construction trades to describe or relate to what you show. You just have to make up some of those words your drill instructor used in boot camp!
I can see what they’re trying to do and what they did not accomplish in your photographs.
Have your contractor bring the blueprints to that house with him to the meeting.
Look on the building permit (which must be posted on the property) and get the name of the building inspector that inspected the framing rough in. That is the AHJ you need to be talking to. No one else in the Codes Department will help you.
I will contact you when I get to the office later today.
You can contact me by phone at any time.
