Tying back a bay that has some lateral movement

[philrobinson]

Hi Guys new on the site and looking for some advice. I have a big bay with a large window below and above. The area in the middle of the 2 windows is showing some lateral movement away from the house and I have been told that I need to tie it back to the main house construction.

I was thinking that i need to forms of straps to cover this off before having new windows installed. A tie on from the main house joists at floor level onto the wall taking away all the internal plaster to make sure its attached to the brick internally and then also a straight horizontal tie on either side of the bay bending it around the wall on each side to hold the top level of the bay also.

Am I correct in my thoughts and should I do anything else please.

Thanks Phil

hole through the wall at joist level, galvanized wire rope cleated to the joist on one side, similar hole through wall at other side of the bay, thread wire rope through, then using a Tifor pulling device, tension the rope and cleat to second joist.
