ᐅ Is Structural Engineering Dependent on the Material? Building with Aerated Concrete T10

Hello,
I have a general question. Originally, we planned to build with Poroton T10 blocks.
The detailed design, structural calculations, and thermal insulation verification were all based on T10.
However, since we are having significant issues with our construction company and want to separate from them after these approvals are completed, planning to contract the trades individually,
I’m wondering if the structural calculations and thermal insulation verification are tied to the specific block type.
In our building area, roughly 80% of the shell contractors use aerated concrete due to easier handling and lighter weight, I assume.
Since shell contractors are currently in short supply here, I’m questioning whether it’s a good idea to insist on Poroton for the shell builder. If they even submit a bid, I expect it would be marked up.
So my question is whether anyone has faced a similar situation. Not necessarily the difficulties with the construction company 😉
As I understand it, using a block with the same compressive strength class and equivalent U-value should not be a problem. Or am I mistaken?

I’m feeling too lazy right now to scroll back through your design thread: do the walls on the upper floor line up with those on the ground floor?
I usually advise not to ask a bricklayer specialized in red bricks to lay white bricks against their usual method, and vice versa. But I would be more concerned about potential issues due to lack of experience with the materials than expecting a deterrent pricing offer. The purchase prices for the bricks won’t differ significantly.Yes, the load-bearing walls are aligned vertically. At least that’s one thing our architect didn’t mess up.

The new structural builder might not want to take any risks and may stick to the planned material rather than using an alternative. However, I would be surprised if your chosen builder couldn’t also work with bricks instead of aerated concrete. It might be more expensive, but a mason doesn't become a mason by working with only one building material. They can handle it as well...
