Hello everyone,
We are currently at the early stage of the detailed planning for building our semi-detached house. One of the questions we are facing is whether to use 17.5cm (7 inches) or 24cm (9.5 inches) thick bricks for the party wall between the two units. The structural engineer/architect has currently planned for a thickness of 17.5cm (7 inches).
We are now wondering if the additional 7cm (2.5 inches) would provide significantly better sound insulation, or if we should rather enjoy the extra 7cm (2.5 inches) of internal width.
Our future neighbors in the semi-detached house value good soundproofing, so I assume they will also use at least 17.5cm (7 inches) thickness.
Thank you very much for your help.

Important is the phrase: according to recognized rules of technology, this should be included in the contract regarding sound insulation. And now the interesting question: in which contract should this be included, given that there are basically two separate building projects? And why use the legal term "recognized rules of technology"? Why not specifically VDI 4100:2012, SST II or something similar?

Just accept it No. The nonsense about recognized technical standards (aRdT) has no place in contracts. Compliance with these standards always applies, even without an explicit contractual agreement. Anything else is considered a defect. Therefore, the specifications must always be defined as clearly and unambiguously as possible. Contractually insisting on compliance with the aRdT is pointless.
And the question about the contracting party is also justified. Who can the client realistically hold responsible for meeting certain soundproofing requirements in the situation of two semi-detached houses designed by different planners and a construction supervisor?
