If the equipment can producing vibration that has to be contended with
design, the equipment manufacturer will provide the forces for which supports
should be designed for. Ask the manufacturer about his experience with the
typical foundation for similar installations.
Incidentally, many of the so called "vibration producing equipment" do not
produce serious dynamic loading on the foundation. For example, many of the
compressors can be installed on a nominal concrete pad. If you have more
information about the refrigeration equipment, please let me know.
