Testing structural engineer costs in Hessen

Good evening.
In Hesse, a structural engineer is mandatory.
My house construction company (general contractor) on my property sent me an offer for a structural engineer they work with.
The offer amounts to €1200 and includes:
CONSTRUCTION SUPERVISION OF A SINGLE-FAMILY HOUSE FROM A STRUCTURAL-CONSTRUCTIVE POINT OF VIEW ACCORDING TO HBO: §59 AND 73:
INSPECTION OF THE REINFORCED CONCRETE PARTS, APPROVAL OF THE CONCRETING PROCESSES.

What did you pay for this in Hesse? And is it advisable to find someone yourself rather than taking someone recommended by the house construction company (they probably almost always work together)?

As a rule, no separate structural analysis is required for buildings of building class 1-3. The services can be provided by the approved and authorized structural engineer - see info. The "offer" from the general contractor may therefore be pure money grabbing ...

Better hire an independent client advisor/expert who represents your interests and monitors the services of the general contractor.

Hello wpic...
What you wrote, I forwarded to the construction company. Including the folder "bauherreninfo".
This is what they wrote back to us:

Good morning Mr .......,
regarding the structural analysis check - your construction project does not require a structural analysis check, but you will need a structural engineer to inspect and approve (construction supervision) structurally important points: ceiling approval, basement, and some other load-bearing elements. This is also mandatory in Hesse. In the meantime, you should have received the offer from our structural engineer by mail; if not, let me know. If you do not like his offer, you will have to find one yourself before the start of construction.
Regards .........

we paid €450 for this mandatory examination of the state of Schleswig-Holstein. however, we never commissioned anyone or anything like that, suddenly there was just an invoice in the mailbox. reading it like this, it hit us hard
