o Replace gasket.

o Verify pressure gauge functionality for One (1) Pad Mount Transformer.

• Post-Service: Purge and recharge headspace with dry nitrogen per Standard

• Deliverable: Report detailing recommendations for repair and gauge verification.

E. Standard Nitrogen Recharge Procedure

• Applicability: Necessary for requirements B, C and D after service completion.

o 4 Pad Mount Transformers o 6 pad Mount Switchgears

• Procedure:

o Fill headspace with dry nitrogen to a pressure of 5 psi.

o Maintain pressure and verify no change for at least 15 min.

o Vent headspace to atmospheric pressure.

o Refill headspace with nitrogen to 2‐3 psi.

• Requirements: use calibrated pressure regulation equipment and dry nitrogen supply.

G. General Comments and Assumptions:

• No more than two (2) switches and/or two (2) transformers may be powered down at a time.

• NCCIPS Electrical personnel will perform all necessary switching to remove power to switches before service.

• Schedule for services shall be coordinated with the government’s technical representative not less than five (5) working days prior to performance of services. If downtime is required, work will be scheduled at the earliest convenience of the affected data center clients.

• NCCIPS team members will review the Dissolved Gas Analysis (DGA) baseline fluid test reports once the Contractor delivers them.

• The Contractor will notify the government’s technical representative of any engineering change notices and any production enhancements.

• At the conclusion of each service visit, an electronic report summarizing the performed service, findings, and recommended action will be made available to SAIC’s technical representative for review.

H. Payment Schedule:

DELIVERABLES PAYMENT

Fluid Sampling/External Sample Valve Install/Leak Repairs 80% of total contract value

Delivery and NCCIPS approval of Fluid Sampling Reports 20% of total contract cost

I. Contract Type:

This will be issued as a Firm Fixed Price project.

J. Special Terms and Conditions:

a. Pricing shall not include labor for any additional testing services not specifically covered.

b. Pricing shall not include replacement of any failed equipment or devices, purchase of such items will be authorized as a separate procurement prior to delivery of items.

c. Contractor shall guarantee the use of new equipment only, no remanufactured products, and no gray-market items.
