Underpinning
Underpinning
(OP)
A code official has presented the attached detail for underpinning of an existing party wall. The detail was generated to preserve the neighbors ability to develop their property in the future by restricting the underpinning from extending into their property past the face of the party wall.
I am not a fan of the detail, am interested in your thoughts.

This looks like a good job for steel micropiles installed under the existing wall. Then you can build your structure to the right side.

In your photo, I would want the hooked bar going to the back face.
