Almost always the result improper footing under the pier. Have specified many underpinning repairs where that has happened.
For 2-2x10 bearing on an 8" wide pier … that would be 3" x 8" x 1,900 psi = 45,000 lbs. Thats not how ya do that calc, but you get where I am going with that. The typical pier loading is not even close to the actual capacity even at the upper end of typical pier spacing. Been there & done that with actual structural calculations.
Not really standard practice, but good practice to minimize building materials. Not a defect for a home inspector though.
Very true, and another reason to have the pier cap
The bottom line is a pier with the blocks transverse to the girder is just not a home inspection defect based on that alone. If I got called in to evaluate a typical residential pier just because it was transverse to the girder with that pier spacing I would have coffee shooting out of my nose … :mrgreen:
