New build issues with floor - should I get 3rd party advice?

New Build Inspections

We have recently bought a new build maisonette and, after moving in some furniture, noticed that some area in the kitchen floor feels excessively bouncy/soft. The issue looks to be related to the installation of an acoustic batten system for soundproofing and we are currently in talks with the developer, but the builders argue that everything has been installed properly.
There are a lot of details and an ongoing investigation, but my main concern is that none of the involved parties (developer, builders, architect, etc) is looking into how to actually fix the issue or take any responsibility.

My preference would be to get an assesment, with suggestions on how to make the floor more rigid, from a specialist (these batten systems seem very complex!).
Does this mean that I am "bypassing" the developer and he will not cover any costs?
Should I get a surveyor first?
Even in the case that eveything is installed according to regulations, is this not a major snag issue?

that depends on its design parameters , can you find out what system has been used and speak with the companies tech dept ....to find out what level of spongyness is acceptable

do you have any video footage you can send so i can see what it is you have and are experiencing ?

Thank you for reply.

I know the acoustic battens are from JCW and I was thinking to contact them directly. I even suggested the developer to arrange for one of their tech guys to check out the issue but the developer was not keen, as he is looking into other ways to figure out whether is something wrong or not (his exact wording was "I need more information before I go to JCW").
Maybe I should push him more on this direction.

I will try to record a video in the following days.
I may have failed to describe the issue properly as it is more of the bouncy/vibrating effect that we are worried about and not the softness which is expected in such installations. In particular, we noticed that if someone is standing in the problematic area then she can clearly feel vibrations from another person casually walking a few meters away in the same room. Similarly, furniture starts to rattle when walking around the room, and for any impact more than a regular step the floor feels more like a trampoline than something solid.


PS. There is an interesting story with the installed system brand. The builders initially claimed that it was from Durabella, as per the property designs, but they discovered a few days ago that actually they have been using JCW. Needless to say, they then went to great length to prove that the two systems are "equal" and they did follow the JCW specs. In any case, this fact alone does not inspire much confidence in their ability to properly install such systems...
