Hi all,
We are doing a new build of 3 houses, and have been told by the sound testing people that the wall divisions have been specified incorrectly, and hence we will now have to do alot of remedial work to get them to pass the relevant tests.
These have been done to the specification of the architect, so we feel that they should meet the remedial cost of the work in terms of labour, as well as the cost of wasted materials.
Has anyone come across anything like this before? Not trying to make extra here (hence only looking for extra labour + wasted materials), but don't see what's the point of taking professional advice if this happens.
Thanks!
I don't know anything about sound testing wall divisions or even walls, other than that they keep people out, but as someone unfortunate enough to be an electrician I can relate to the type of problems you are having.
I know certain LBC's can have different rules from others, is this problem something small that is preventing the wall from passing, i.e., would it pass in another Borough? I would request - in writing - information detailing precisely what the problem was and outlining the standard it needs to be in order to pass. If you can't, and they haven't request they cross reference the unsatisfactory result against the specific building regulation which has caused it to fail, and then, if it's not too much hassle have these results inter verified by an independent expert.
I'm not actually sure where LBC's stand on fabricating their own rules on building regulations and raising the bar in certain areas (like the examples below) and how they are obligated to make this information available to architects and contractors.
The LBC of Westminster have rules stricter rules on fire rated cables than other LBC's, and certain LBC's insist on gas and water main earth bonds being 16mm2, where the Regs would permit 10mm2. Although the Architect may well still be liable there could be an unusual rule like the one's above, unique to the LBC which he was not aware of which is preventing them from passing.
By carrying out the following 'detective' work you should be able to ascertain exactly who was at fault, it does sound to me like the architect was responsible for making sure the wall complied with the LBC's and the building regs standards.
One possibility I wouldn't rule out is (if I'm correct and a silly 'quirk' is preventing it from passing, not a dangerous defect) is offering someone a 'drink' to pass it. My experience with these LBC building inspectors is that they're a joke. Most couldn't build lego.
I actually met a guy from the council once involved with environmental safety who was doing a 'sound test' on a gate in a block of housing association flats because it was making too much noise when it closed. He ordered a replacement electric gate and didn't even check how much noise it made when it shut! The guy was such a jobs-worth tool it was almost beyond comprehension.
