The bco has been for a site visit today and he highlighted a potential problem with running a soil pipe in a channel 120mm deep cut in the party wall. In his email the bco refers to a cavity wall but in fact the cannel is cut in the solid wall. He writes
the proposals of having the soil pipe inside the cavity wall needs to be reviewed. The issue that needs justiification is the sound issue. As a party wall it cannot be adversely affected by the works and removing one skin could make it worse.
The bco asks for the matter to be reviewed by an architect. From your experience what is a reasonable sound insulation solution that will ensure that my neiboir boesnt hear me flush the toilet? Thanks
