Architects / Civil Engineer Service, Execution Plan, Scope

Hello dear people,

thank you very much for the acceptance. I am proud to be part of this forum. After deciding to build a semi-detached house (not basemented), my hopes lie in benefiting from you and your experiences.

My first question is immediately about the planning. I know a civil engineer who wants to create my planning with the help of an architect. Everyone focuses on their tasks. However, that was perhaps a bit premature. Because I have now dealt with it more closely. The service phases of the HOAI include 9 phases. 1. Basic evaluation, 2. Preliminary planning, 3. Design planning, 4. Approval planning, 5. Execution planning, 6. Preparation of award, 7. Participation in award, 8. Object supervision, 9. Object care.

The services are created up to phase 4, meaning the approval plan. That means the complete building application is submitted to the building authority. That sounds great, but I have just reached the point where I say the essential work only starts here. How is the bricklayer supposed to know how to work? No one on the construction site knows how to work. There is neither information about the thickness of the base plate, nor ceiling, screed, etc. Do you agree with me? Or am I seeing this incorrectly? It could also be that I show the workers the respective plans and they then perform the required services based on my plan. For example: I show the carpenter and roofer my plan. He creates a plan for himself on how to build the roof truss. Or the electrician. He gets my drawing and creates a solution based on my drawings. Also the heating engineer and plumber, screed layer, etc.

Can you tell me which execution plan should at least still be provided by the architect or civil engineer?

Thank you very much for your help!

Best regards Kalle

The question will be clarified in the
5. detailed design
6. preparation of awarding

What do you need a structural engineer for! Leave the structural engineer "aside" and hire an architect for service phases 1-8 or hire a general contractor.

....why do you need another source of error?! Several tasks and 1 responsibility.

There are many possibilities...
For the building permit, there is a structural analysis, which is done by the civil engineer, an architect cannot do that.
It contains everything the trades need to know about the construction.
It is still advisable to have the architect carry out service phase 5 and then service phase 6, and the civil engineer service phase 5.

It is still advisable to have the architect carry out performance phase 5 and then performance phase 6, and the structural engineer performance phase 5.

But why? For me, the structural analysis is done by the engineer of the structural builder, and that's it. If necessary, you might still need an energy consultant, and that's it.

Many different responsibilities = many potential sources of error

As I said, there are many possibilities. After all, you also have a civil engineer, just not directly contracted, but through the shell builder. Personally, I wouldn't do that, because they usually work in the interest of the shell builder and not yours.
