We’re looking at a fairly large home on a basement. It will have an LVL beam down the middle to support the floor. With the posts about 11 or 12 feet apart, the reaction at each post location is about 12,000#.
The jack posts the local lumber yard carries say they’re “tested to 15,000#”. Does this mean that’s the capacity they *FAIL* at, or is their typical “in service” capacity ?
I can’t find anything about it on the ‘net, and no one at the lumberyard seems to know anything. (Big surprise there)
Can any of you help me out ?

*Ron:For the same price, or maybe even a little less, you could use standard steel pipe or square tube (very easy to finish off later)sections that a structural engineer could size for you. You will need to have a plate welded on top of the column to comply with the bearing requirements for the LVL and a base plate on the bottom that will sit on top of the footing. Of equal importance is to make sure the concrete footings under those columns have been properly sized based on your soil condtions and have appropriate reinforcing steel.Dave
