You should make your own posting and reference the original post. 

What is the shaft speed?

What is the vibration frequency?

Can you feel motion across motor base and grout top?

What is the condition of the grout under motor and anchor bolts?

Can you post photos of the motor, base and foundation?

Has good shaft alignment been done?

Has a structural impact test been conducted to detect resonance?
