- 40 year old apartment block
We’ve received conditional approval to install our flooring from the EC. All conditions included are within by-laws, but written as “possibilities” eg.
“If requested by the owners corporation, within one month of completion of the works the owner at his own expense must give the Owners corporation a report signed by a qualified acoustic engineer certifying the acoustical star rating, according to the current ACCC guideline, achieved by the non carpet flooring as installed”
An engineer for the company recommended by the EC has stated in writing to us:
“In my professional opinion, post-installation impact noise isolation testing of your bamboo floors will not be required given that your apartment does not lie directly over another apartment. Because your apartment lies over a carpark, there is no requirement for your bamboo floors to achieve and LnTw rating of 45.
With regard to noise transfer from your floors to apartments horizontally adjacent, this is more an issue of airborne noise transmission rather than impact noise transmission. There will no issue of footfall noise to your neighbours provided that your floors are isolated from the walls and slab correctly.”
When we showed the above letter to the EC, they’ve said that the engineer is incorrect and still want enforce testing at a cost of $1900 + GST to us.
So my question is, are we missing something, or is this as illogical/ irrational as it sounds?
Can we do anything further to save us the inconvenience and the money?
