Prefabricated house construction - who creates the plan for the earthworks?

2021-11-16 16:22:03

Our civil engineer planned and carried out the work based on the drawings from the architect and the structural engineer. The transitions from the concrete floor slab to the timber construction were coordinated between the civil engineer and the carpenter. I only ensured communication between them. All regional companies that know each other and like to work together (this was a criterion in our selection).

Many prefabricated house manufacturers have their favorite floor slab/basement contractors they work with. I would always have this service handled by the house company because of the warranty.

Good tip!

Would you like to tell us why you separate basement/slab and prefabricated house builder? We are building a prefabricated house without a basement/with a slab and, due to expected interface problems etc., decided not to have the slab made by another company. As a somewhat cautious layperson, I was worried that we would get caught between the prefab manufacturer and the slab builder. I don’t know if we are paying an exaggerated amount of money for the slab and what belongs to it (9.40m x 9.40m about 20,000 euros), but it is worth it to us. We were told that if we separate the slab from the house construction package, the slab builder must also take over the statics. (?!?) I understand correctly, you are building the prefabricated house with a basement and additionally need the slab for a garage? May I ask in which federal state or region? Just out of interest.

I would (as the Bavarians so nicely say) "never ever not" release a house provider from the responsibility that the house and its foundation slab fit together exactly. So why actually the commitment to a "prefabricated" house? Your avatar features a woman in a wheelchair – how does that fit with a plot that needs leveling? (Sloping sites rarely have moderate ramp inclines)

I think the idea of a house in timber frame construction is quite good.

Regarding the plot. It is just as it is. Therefore, we have to move some earth from back to front. But the height difference is only 1.8 m over 24 m anyway :-)

We are building a prefabricated house without a basement/with a floor slab and have refrained from having the floor slab built by another company due to expected interface problems, etc. As a somewhat anxious layperson, I was worried that we would get caught between the prefabricated house manufacturer and the floor slab builder. I don’t know whether we are paying an excessive amount for the floor slab and everything related to the floor slab (9.40m x 9.40m approx. 20,000 euros), but it is worth it to us. In this context, we were informed that if we separate the floor slab from the house construction package, the floor slab builder must also take over the statics. (?!?)

Hi Pinkiponk. That was the opinion from various sources so far :)
Of course, there is the interface problem, but it certainly does no harm to get additional offers for certain trades. However, that doesn’t mean that one (I) has to do it that way. And that is why it is good to hear different opinions in the forum :)
The house is without a basement. Floor slab for the house and floor slab for the garage.

I recently saw a house where the builder planned past the property. That shouldn’t be possible.

Who submitted the building application? The property plan is mandatory. Post it here, then we can have a look to see if it works well.

Hi Hanghaus2000. There isn’t one yet. We are still in the snooping phase :-)

You already have the plot? With a slope. Sounds interesting. The forum often helps with deciding where to place the house. Don't you have any idea how it should look?
