Hi,
I am looking to raise the RSJ's in my Kitchen. The RSJ supports the original outside wall and was put in when the kitchen was extended. The work was done prior to me buying the house. I have had a structural Engr around who has said the RSJ that is in situ is sufficient to support the load. The trouble is that the RSJ is sitting lower than you would expect it too, in the kitchen. I cannot see a reason for it having been put in as low as it is and nor could the engr. So I want to support the walls and raise the RSJ's (one on the inner wall and one on the original outer wall) by one course of block. The span of the rsj's is just less than 3M long and the joists above the kitchen run at right angles to the RSJ's. My questions are:
1. Do I need to supports the original outside skin with Strong boys if so how many do you need in a 3m span.
2. How many acrow props do I need for the inner wall for a 3m span
