Comparison of construction performance description! What should we prefer?

Hello,

Excavation of the construction pit for soil classes 3 to 5 as well as the necessary storage on the grundst......(for example, I don’t understand that at all)

That means if the soil report shows different soil classes, it will get expensive because a.) a soil replacement must be carried out and b.) the excavation material must be disposed of expensively => topic additional foundation costs!

Removal of the excess excavation from the construction pit including landfill costs

Sure or assumption? This is included in the scope of services in few construction descriptions (BB); actually "only" in pure developer measures.

Filling of the working spaces with the stored excavation

If and only if the excavation is suitable for this.

Earth is not spread on the ground.... but is included in the landscaping services

What does that mean?

- Basement slab with steel fiber concrete 12cm on 12 cm filter layer of gravel and PE foil covering

Doesn’t exactly sound great ... our slabs are 20+ thick; depending on structural requirements

But without soil report????

In no case advisable! You are the owner and the master of your own fortune – that means you are liable accordingly for negligent foundation work!

Where you – apparently – have such a fear of the topic house construction, why don’t you get external help?

Hello,

------Correct!

Certain or assumption? Belongs to the scope of services in at least construction descriptions (BB); actually "only" in pure developer measures.

-------------Certain!!!!!!

If and only if the excavation is suitable for that.

-Exactly......
Means?


Doesn't read very appetizing ... our floor slabs are 20+ thick; depending on static requirements


Not advisable in any case! You are the owner and the master of your own fate - which means you are correspondingly liable for negligent foundation work!

Where you - apparently - have such a fear of the topic of house construction, why don't you get external help?

No .... as said, I will definitely hire an expert who will inspect the property

So, another week has passed. But overall, a bit wiser. The offer from the BU stands with a plus or minus 3% deviation. At least that's what he says.

So we have an offer for a 120 sqm 1.5-story single-family house in Kfw 70 standard with an air heat pump for 270,000€, but we don't know what it should look like or how big the terrace will be.... no idea. Without a planning contract, we won't get any planning or sketches made. The BU says he will just try to stick to the price. All in all, according to him, it can be at most 3% more expensive. We would agree to that, but we would like to know..... roughly how it will look.

So I have to bother again etc. For now, I have an appointment with another BU who has been locally established here for a while, where I want to get another offer. Let's see where we end up with him, because he has almost the same craftsmen on hand. We'll see.

So far, my favorites are: 1. the aforementioned BU with the 270,000€, 2. House of the craftsmen with 250,000€ + ancillary building costs, so I also calculate about 270,000€ here, 4. Was Stadt & Land...... but that was a quick rejection because they are no longer up to date. The next appointment is on Wednesday... with the other BU... let's call him BU2 here.

I'll get back to you.

Hello Kochones,
it is best to have the tender prepared by an architect. This architect must refer to an experienced structural engineer. This way you get roughly the same information and offers on this basis. Everything else carries a very high risk of being cheated by every company. The money spent on a professional tender is quickly saved later during the quantity settlement. It is very important that there are no unit prices (EP) in the tender, and if there are, have them crossed out and reconfirmed. I have learned from these mistakes. Architect and shell construction company are friends. No chance in court. Many execution errors simply are not remedied afterwards. You never know who is working with whom. Usually, shares of the collected amount flow in the background. And everything is justified by stating that the DIN standard is met. The basic rule is: do not hire any company recommended by the architect! Visit reference houses yourself on the slope to be convinced.
Good luck.

But you also have to stay calm.... at the moment there is quite a lot going on in construction. And you will always get different prices. And the offers are not that far apart. 280 TEU to 310 TEU. Additional costs and fees are of course extra...

But you also have to stay calm.... right now there's quite a lot going on in construction. And you will always get different prices. And the offers are not that far apart. 280 TEU to 310 TEU. Additional costs and fees are of course extra...

That's exactly it....

Developer A says 280K€ all in....

Only one architect says 310 and another 37 for his fee

I have an appointment with another architect on Friday......let's see.....I was there today but he had no time.
