It is seen that all the three constituents of the machinefoundation system, viz., machine, foundation and soil, contribute to the frequency of the system. This system, when subjected to dynamic forces (whether internally generated, externally applied, or transmitted through the soil), results in response of the system.

foundation should not rest on backfilled soil or on soil sensitive to vibration. Block foundation resting on soil should have a mass of 2 or 3 times the supported mass for centrifugal. machines, and 3 to 5 times for reciprocating machines. Top of the block foundation is usually kept 300 mm above the finished floor to prevent damage from surface.
