Extension resting on post bases. Okay?

[Nybyggarens]

The extension is 14 sqm. The main beam consists of two very strong laminated wooden beams resting on 4 quite sturdy adjustable post bases.
The post bases are embedded in enormous concrete foundations in the ground. They protrude about 10 cm.
(the rebar on the right is part of the concrete)

Is this sustainable?
How much load can those post bases withstand?

They easily withstand the weight of the extension. But I had cut off the protruding reinforcement bar.

They can handle the weight of the extension with ease. But I would cut off the protruding reinforcement bar

Good to hear! It just looks so flimsy with four pins supporting an entire extension (well, half the roof is leaning against the old house)

Anyone else have an opinion?
I need to be sure.

No unusual solution for a pillar foundation. In this case, it's even better because the height between the beam and the foundation is short, which reduces the shear force and you avoid the risk of lateral movements.

No unusual solution for a plinth foundation. In this case, even better because the height between the supporting beam and the foundation is short, reducing the shearing force, and you avoid the risk of lateral movements.

Okay! Is there no limitation on how "heavy" the extension can be? (within reasonable limits)

They can handle many tons each, probably 3-4. There is data for similar post shoes here, but it is beyond my mathematical competence to calculate what load a post shoe can withstand.

Okey, thank you for the answer.
