Yes, he did not get the appointment. In his letter, it said that I should give him the contact details of the foundation slab builder so that he can get in touch with him regarding construction supervision. I also gave him the implementation calendar week. I assumed that he would then take care of everything else.


In Hesse, I need a structural safety certificate for the building authority (§ 73 HBO paragraph 2). The structural engineer was registered as a certification authority at the building authority.


Not construction manager, but "building expert." I have additionally hired him as a consultant; he supports me with the project and with the acceptance of the trades.


According to the structural engineer’s letter, it is up to the foundation slab builder; he (the structural engineer) wants to contact him regarding construction supervision. To me, that means the two parties are to sort that out among themselves.


To my knowledge, the construction manager was (also) not on site.


Hehe, I have pictures showing that steel is inside and not corpses, but that is not enough for the structural engineer. I have the impression it is not enough as a principle. I cannot reach him by phone, neither I nor the foundation slab builder get the requested callback. He demands from me a comprehensive liability release by registered letter or he will resign his office vis-à-vis the building authority.

Sounds very complicated; I guess I won’t get around a lawyer. :( Whether this can be clarified amicably in 4 weeks (when the house arrives) I seriously doubt...


Good question, I don’t know. I have to ask the foundation slab builder. But it can surely be tested by continuity measurement or similar, right?


He must, according to § 73 HBO paragraph 2, verify that it was executed according to plan.


Yes.


Different states, different laws... In our case, it is laid down in the Hesse Building Code (HBO).


No, it is a small single-family house without a basement. Ground floor + 1 upper floor in timber frame construction.


Because of the missing confirmation from the structural engineer. This is required by the building authority.

I would exempt him from liability. What is supposed to happen? The shell builder is anyway under warranty and I've never heard of a normal new single-family house having structural problems. That would be extremely gross nonsense. I would take it easy and definitely not involve a lawyer etc.

See it like : The liability exemption for the structural engineer is the pragmatic solution. The risk is minimal. All other solutions will lead to significant delays. Discuss the issue kindly but clearly (it hasn't gone well, the solution is...) with your site manager, then you can "be in good standing with him." It might help you at some point in the construction process.

Also in NRW, according to the building code, a "construction supervision by a licensed structural engineer/inspector" is required. The completed construction of the shell must be reported immediately to the building authority in our case and a test report from the structural engineer must be submitted.

Well, in NRW it is still quite relaxed. For an average single-family house, for example, the architect plus professional experience in structural engineering is sufficient (that is enough to be registered as qualified). The inspection is also to be carried out only on a random sample basis.

Unfortunately, I can only report this based on my own current experience. The building regulations office is currently getting on my nerves and demands an "immediate" structural analysis report after the shell construction is completed. They even issue corresponding registration forms together with the building permit that are to be used for this purpose. The completion of the shell construction (one week in advance!) must be reported on it and the structural engineer's inspection report must be attached immediately! Especially with a prefabricated house that can be erected within 2 days, this is a bit absurd, but that’s how it is.
