BD Luka is a new residential building with 3 basement floors and 16 floors above ground. The investor has built these apartments not to be sold, but to rent them for long term.

Since the building is situated right next to Luka Station on line B of the Prague metro network, it posed a challenge for the designers to meet the noise level criteria. The vibration isolation study concluded that in order to reach this value for the apartments, the vibration isolation system needed to have a resonance frequency of maximum 13 Hz.

The height of the building and the resulting load values made it almost impossible to propose any other solutions than Stravibase VHS which can take up to 12 MPa. The vibration cut was located mostly above ground level which allowed a clear approach for modelling and a solution without perimeter isolation. The investor chose the 3-layer Stravibase VHS bearings (having a resonance frequency of 13 Hz).

After the installation, the measured noise levels in the apartments were very similar to the estimations based on the FEM model. The noise limits were achieved. The building was also awarded for its architectural features by the Czech real estate developers.
