What does it means?
From an structural engineer report
''Posts should be blocked solidly in the joist cavity''
Thank you

Blocking a post would fix the post so that it can't move horizontally in any direction. Blocking is usually a horizontal framing member between studs. In your case the blocking would be installed around the post so that the post could not move.

Thanks for reply, blocking the post in the joist cavity ,does it mean cutting a hole on the bottom plate/floor and setting/blocking the post on top of the joist?

From my experience solid blocking for posts always meant to put solid wood (usually joist cut offs) between the underside of the plywood where the post sits above and the top of the wall or beam the post is over. The blocking needs to be as big as or bigger than the footprint of the post. This carries the point load to the beam or wall. If there was no blocking the floor would settle under and around the post at some point in time.

Thanks for all the replies,the report points out the need to beef up the floor joists where the posts will seat .The new built up beam is 3-2x10 nailed to the existing joist bearing on a steel beam and a LBW. Im an absolute novice , I got the report to see if some parts of the reno Im doing at home were doable but the quotes I got from different contractors to do the job were much more than I anticipated so for now Im just traying to understand what has to be done.
The diagram shows the post on top of the new beam, there is no floor drawn
I thought the joist cavity refers to the space between the joist, therefore my question about setting the post on the built up joist not on the floor above it .
Again thank you all for the help
