Received GU offer - Assessment of fair offer?

Earthworks are actually not included. - if excavation cannot be stored, additional costs. - soil replacement, additional costs - it is not clear whether the gravel container will be charged, only that one is planned

Augsburg is unfortunately anything but a bargain hole.. Just the proximity to Munich makes all costs skyrocket..

Then the offer is not good, but too cheap. See above.

Yes, we might register with the Bauherren-Schutzbund.. Do you have any experience with that?

They only check the contract and the associated construction service description. But it is also possible that you can have a construction service description checked independently. There are some here who have made elaborate tables for three offers.

Basically, I am always very suspicious of craftsmen at first whether there is not a preliminary overcharge..

Well, ultimately it is not a rip-off if you clarify what the customer (does not) buy. And you should also treat your contractual partner with trust, so a review and not the cheapest offer is decisive.

See attachment for the description

Look, the removal and disposal is not included. But that is also rare.

I believe you... let's see if it becomes a gold toilet bowl or not :D

You know, it doesn't have to be made of gold. But your wife would like the one without a rim, you want the lotus effect. Then the gentleman doesn't sit comfortably, a comparable model is chosen and suddenly the toilet costs 800 instead of 150.

I am currently tending to hire a construction supervisor (from the IHK) locally. (150 EUR/hour)

Look, the removal and disposal is definitely not included. But that’s rarely the case anyway.

Yes, tomorrow I will call about some points with the general contractor and also address this in more detail. Recently he said I shouldn’t expect any more additional costs, but the contract does include this clause for possible extra costs.

:D

He might actually be right. With what he offers in the [Bauleistungsbeschreibung], you generally don’t have to expect additional costs. Unless you have extra wishes.

And for him it is also clear: what he does not offer, you have to pay for anyway. For him, those are not extra costs.

Yes, primarily a very bad experience with our electrician, who sold KNX but ultimately had no idea about it. After the electrician gave up on the programming, I dealt with it myself and taught myself. The ETS 5 and a server (for me the Gira X1) were then necessary investments (ETS on sale 600€, X1 about 680€). Plus the components misplanned by the electrician, but that's another topic. If I had to do it all again, I would prefer to have the electrician only lay all the cables (with precise instructions where KNX cables and where 230V should go) and then do the rest myself in the control cabinet and also procure the KNX devices myself. The problem is, however, that you (at least I) are not allowed to do the 230V wiring yourself. That means connecting the blinds/rollers, lamps, sockets to the KNX actuator yourself is not permitted for an electrical layman. Currently, I still have a renovation running that is to be rented out later. There, I am also considering whether to install KNX – now that I can at least parameterize & program myself. But in that house, there isn’t much electrical aside from lamps and sockets. KNX is somehow over the top there, and in rent, you definitely won’t get that back.

The plan for me would also be to really just have the electrician lay the cables according to agreement where which KNX cables are needed and for him to connect them at the control cabinet and give me a clean handover so that we can program it ourselves accordingly. The question is still whether the electrician installs the KNX stuff you bought yourself?! Or does he only install the stuff purchased through him?! Which software do you then use on the iPad / phone for the home control?

We had bought it through the electrician and he also installed it. Actually, the complete package was commissioned. Today I would want to do it differently, namely only have the cables laid and connect all KNX components myself – but as I said, unfortunately not allowed. The background is just that our electrician (because he has no knowledge of KNX, only attended all the courses on it) botched the wiring, and as a result, for example, directional functions in KNX did not work properly. Troubleshooting was really time-consuming. For use via mobile, you need a KNX visualization server, with which you are also tied to the software on the phone (yes, I know there are solutions with a Raspberry and free software with more configuration options). We have the Gira X1, but there are various others. The visualization is a bit nicer with the Gira Home Server, but it also costs three times as much. In hindsight, I would like the Jung Smart Visu Server a bit better, since here the functions from one room are displayed one below the other with sliders. With the X1, I have to go back from each function to the room menu. Jung, however, looks more technical and not so "pretty". Just google KNX visualization servers, you will find websites that compare the systems.
