Hello everyone,
in my building in Bosnia which dates back to the '60s recently was installed a brand new elevator.
The building consists of 6 floors and the elevator is installed around the steps in the center.
The contractor suggested to go with a traction motor with a motor room on the 6th floor because of better performance, easier maintenance etc.
We, tenants from 5th and 6th floor, were worried for the noise and vibration that such room can cause but the contractor assured us that those motors are new, with new technologies and noiseless.
The hoistway is a metal frame anchored on the sides of each floor covered by gypsum panels while the motor room is at the top.
As you can see from the pics there is no proper acoustic nor vibration isolation at all, the motor room seats directly on a metal panel of about 1 cm and is also only covered by gypsum panels, with light escaping all over the places, including around each door on each floor.
The elevator is 2 months old, if I understand correctly the motor is a two step motor with 4kW of power, made in Turkey.
From the first days we complained about the noise and vibration produced by the elevator, having a hard time with the contractor that states that everything is done professionally and according to the rules.
On every start and stop of the elevator I feel the vibration in my apartment on the 5th floor, with the radiators im my living room clinking, the mug in my work room clinking, feeling the vibration when laying in the bedroom which is far 8 meters from the front door, while the noise is audible from start to stop in every room. The external wall is 40 cm thick, I am literally woken up by the elevator every morning by the first tenant at 6.

The start is a deep sound, I suppose a structural vibration and it the worst part, then I hear the motor working and lastly a hard clamp, which should be the break, which again produces a vibration and a big noise.
The contractor states that he adjusted the break as much as he could, but the results are none.
Attached you can see how the work is done and some video of the noise and the motor while working, live is much louder than filmed on the phone.

I need help on how to address the situation, and what steps can be done to remove the vibration and the noise.
For the vibration any recommendation?
I asked to put better rubber pads, possibly add extra pads between the motor and the metal construction, maybe VFD? But I'm worried about the base that is a simple metal panel is the main issue.
Would a isolation of the room with rock wool and gypsum internally help?

This elevator is ruining my life... thank you for any help
