RFP No. 75N98026R00114 RFI No.2

RFI # RFI Subject Reference Information Requested NIH Response 8 VFD Please clarify the required scope of annual VFD preventive maintenance. Does the Government expect PM to include:

Visual inspection Cleaning of enclosure Fan inspection Fan replacement Capacitor testing Thermal scan Torque verification Input/output voltage testing Current balance Harmonic review Event log review Parameter backup Firmware verification Operational testing Alarm history review Or is PM limited to manufacturer-recommended inspections?

The scope of the annual VFD preventative maintenance shall follow manufacturer's recommendations, codes and standards.

9 VFD Will the Government permit energized testing during PM?

If so:

Will arc flash studies be provided?

Will PPE requirements be provided?

Will shutdowns be coordinated by NIH?

Shutdown Requirements Many VFD maintenance activities require de-energization.

Please clarify:

Which VFDs may be shut down during PM?

Which systems require after-hours outages?

Are shutdown windows included in the base contract?

The contractor shall request a shutdown for any preventative maintenance that will introduce risk to the equipment or staff. Shutdowns will be coordinated and scheduled per NIH Utility Shutdown policy and procedure. All VFD's in this contract can be shut down during a planned outage. Due to the space served by this equipment these shutdowns will typically be performed off-hours (normal working hours).

Date of Submission:

Company Name: Various

Please clarify whether PdM includes:

Infrared thermography Ultrasonic inspection Capacitor ESR testing Motor current signature analysis Bearing analysis Power quality analysis Or only recommendations resulting from visual inspection.

The scope of the annual VFD preventative maintenance shall follow manufacturer's recommendations, codes and standards.
