Notify the Engineer, in writing, immediately of any unscheduled shutdown. Permit Owner’s personnel to work with Contractor’s personnel, as deemed necessary by the Owner, to maintain the facilities in continuous satisfactory operation. Fines levied by regulatory agencies resulting from unscheduled shutdowns or interruptions of continued safe and satisfactory operation of the facilities shall be the Contractor's responsibility, if it is demonstrated that Contractor was negligent in the Work or did not exercise proper precautions in conducting the Work.
