the Practical point of view The
The foundation must be protected from
machine oil by means of acid-resisting
coating or suitable chemical treatment.
coating Machine foundations should be taken to a
level lower than the level of the
foundations of adjoining buildings.

properties PERMISSIBLE AMPLITUDES
The permissible amplitudes are generally specified by the
manufacturers of machinery. The permissible amplitude
of a machine foundation is governed by the relative
importance of the machine and the sensitivity of
neighboring structures to vibration.
For foundations of sensitive equipment such as calibration
test stands and precision machines, the design criteria
should be established either by the user or equipment
For such installation in which the equipment itself is not the
source of vibration, it is necessary to evaluate the
ambient vibrations at the site and provide suitable
isolation in order to contain the amplitudes of movement
within acceptable limits.
