Buildings are designed to withstand vibrations from passing trucks, traffic, railroads or subways.

To protect your building, assets, bridges, tunnels etc. the DIN4150 recommends maximum values to prevent damage.

Profound VIBRA is measuring in compliance with the DIN4150, DIN4150-3 80Hz and BS7385 250 Hz.

 

Type of structureGuideline values for velocity
in mm/s in horizontal plane of the
highest floor, at all frequencies
Buildings used for commercial purposes, industrial buildings
and buildings of similar design
10 mm/s
Dwellings and buildings of similar design and/or occupancy.5 mm/s
Structures that, because of particular sensitivity to vibrations are not classified
as described as buildings or dwellings and are of great intrinsic value, for
example listed buildings under preservation order
