Comment on Botched structural repair?

Splitting the 2x8 by not drilling a pilot hole and failure to fill all four holes in the top of the jack would likely be an instant failure by the building inspectors here.

“You only need 2, it’s not going anywhere”
Also most of the bolts they put in are either crooked or not fully drilled in.

International Residential Code R407.3 is pretty clear about the post needing to be Schedule 40, 3” in diameter. IMO, this is not code-compliant.
“The columns shall be restrained to prevent lateral displacement at the bottom end and attached to framing at the top. Wood columns shall be not less in nominal size than 4 inches by 4 inches (102 mm by 102 mm). Steel columns shall be not less than 3 inch diameter (76 mm) Schedule 40 pipe manufactured in accordance with ASTM A53 Grade B or approved equivalent.”
The column is clearly not 3” diameter, nor schedule 40. The number of missing bolts in the bottom would fail the lateral movement restriction. The IRC is almost certainly referenced by your local building code. For example, in NY it’s at https://codes.iccsafe.org/content/NYSRC2020P1 , and for Washington
https://codes.iccsafe.org/content/WARC2021P1 . You should be able to find the referenced code for your state.
502.5 mentions span tables you can use to determine if the spans are compliant. I’d wager they aren’t, given the shoddy work.
Those span tables are in 602.7(1) AND 602.7(2).
I can’t remember the IRC code that says all holes must be filled, and it’s already past my bedtime. I’ll do some more searching tomorrow.

Wow thank you so much. I was trying to find codes earlier but was flustered and gave up after getting too frustrated with google. This is really good stuff for reference. Very much appreciated!

also does a good job of breaking down the column types.
