Case Study

• A bespoke structural elastomeric bearing for the structural isolation of buildings and other structures

• Series of elastomer pads laminated to formwork

Stravibase SEB

SMART Byty apartment buildings are situated very

close to Nové Butovice metro station and just a

few metres from the tunnels in Prague. The roughly

300 apartments are equipped with energy-efficient

intelligent technologies.

SOLUTION

The tunnels next to the buildings posed a challenge

for the designers to meet the strict noise level criteria.

The acoustic study concluded that in order to remain

below the limit in the apartments, the two buildings

closer to the tunnel should be constructed on a 11 Hz

system, while the other two buildings further from the

tunnel require a system with a resonance frequency of

15 Hz.

Based on the vibration isolation study, CDM Stravitec

offered the Stravibase SEB system for the project, with

50 mm and 30 mm high bearings. The vibration cut was

located at Level -2, on top of the walls and columns,

just below the floor slab of Level -1.

After the installation, the building received all the

permits and the residents are enjoying, since their

move, the quick access to the metro without being

disturbed by it.
