673CS R1 NORTH UPS

03 Sep 2024- Added Q&A for vendors to ba able to complete their quotes 20 Aug 24 - Added a wiring diagram and investigation report with battery information The Government intends to Replace end-of-life batteries supporting R1 North ALMR site. R1 North provides line of sight communications capabilities to DOD and state agencies supporting JBER and Anchorage. Services supported include emergency services, base security, range control and base operations. Currently if power is lost services provided could be interrupted and equipment damaged. The government intends to establish a firm-fixed price contract for the following:

The contractor shall provide all management, tools, supplies, equipment, and labor necessary to repair and provide one time service of onsite Eltek Uninterruptible Power Supply (UPS). These services shall include any equipment, wiring, or infrastructure to ensure the Contractor's proposed solution is compatible with the Government's current infrastructure without additional Government expense. The Contractor shall follow all Federal Communications Commission (FCC), Public Utility Commission (PUC), Department of Defense (DoD), AF, and industry standards for this requirement.

1.2 SPECIFIC REQUIREMENTS: Listed below is a synopsis, please see PWS for full requirements 1. New Batteries a. Remove and dispose of current batteries per EPA standards. b. Provide and install 48 sealed VRLA batteries, utilizing proper torque values (where applicable). 2. Visually inspect conditions and appearance of the following:
