ᐅ Prefabricated Basement – Direct Contracting Instead of General Contractor
Created on: 24 Apr 2021 14:10

rdwlntsWe are planning to manage the basement construction ourselves and would like to prepare for further planning with the basement builder. Who has experience with this? What information does the basement builder usually request? Have you done the electrical planning yourselves and passed it on to the basement builder, or did you involve your electrician? Is it sufficient for the basement builder to have the locations of the power outlets, heating connection points, network sockets, and switches?
Additionally, I am wondering why our general contractor (GC) typically covers the finished basement walls with Rigitherm (a sandwich panel made of drywall and insulation). At least the living areas in the basement are finished this way, while the hallways are covered with drywall only. The electrical installation is then hidden behind these panels instead of being embedded in concrete. Although this saves on drilling and chasing into the concrete and provides some flexibility over a longer period, it doesn't seem very common. I haven’t found much information about this online. Is such wall cladding really necessary in a KfW40+ house with 20cm (8 inches) perimeter insulation? What do your concrete basements look like?

You will need to involve the electrician for the grounding of the house. The proper installation must be documented, and the electrician must confirm this with the utility provider during the service registration.
If you manage the basement construction yourself, you will have to coordinate all the interfaces. Who handles the structural engineering? Heating? Ventilation? Water supply? Wastewater?

OK, thanks.
The underground construction is done by the civil engineer. I’m not sure about the documentation yet. Good point.
Structural engineering is the responsibility of the basement builder.
Heating, ventilation, plumbing, sewage, and electrical work are handled by the general contractor.

The documentation must be done together with the grounding ring; without documentation, it is practically worthless, and access to the information that the documentation must show will not be possible for much longer.

As always, including in the linked post, well written but somewhat negative, even though I always appreciate your opinion! With that logic, almost every DIY effort would be doomed. If you make a ring crawl space collector yourself, you’ll already be freezing in winter, and all guarantees on heating, underfloor heating, and plumbing are gone...
The general contractor (GC) handles the basement planning, and the basement builders carry out the construction. If the plans were wrong, the GC is responsible; if the basement was poorly built, the basement builders are responsible. The GC also inspects the basement before the house is erected, acting as an additional inspection point. The client basically acts as a mediator.
Of course, you need to be more careful and should only rely on well-known, trustworthy professionals in their field. Apart from a possible scheduling conflict, I regard the issue as manageable. For a 10,000€ (about 10,000 USD) saving on the basement, plus hopefully nearly another 10,000€ by omitting unnecessary sheathing on basement walls, the desired goal is certainly worth striving for.
What does the forum think about basement wall sheathing in already well exterior insulated residential basements (KFW40)?

Warnings about potential liability shifts and the reminder that "the client should stay alert and not take on the warranty burden themselves" are not the same as painting a doom-and-gloom picture that construction sites are filled only with fools and crooks. There are certainly streets where not a single "Fleischerhaus" can be found.
