About this file
This document is a Request for Quote (RFQ) issued by the American Embassy in Brazzaville, Congo, seeking a comprehensive Test and Balance (TAB) for the chancery building's cooling system. The requisition (PR15444299) covers performing a TAB on air handling units (AHUs), addressing operational inefficiencies noted in the 2024 Annual Facility Condition Survey. The system, which has been running for 16 years and last underwent TAB in 2008, has experienced performance issues in maintaining proper supply air temperature setpoints, as verified during recent Building Automation System preventive maintenance sessions.
The RFQ includes potential contractors (Precision Test and Balance and KSI Resources) and is supported by funding and attachments such as an Independent Government Cost Estimate. The solicitation targets optimization of HVAC systems, with a delivery date of September 30, 2025. The document shows the requisition is in a submitted status, pending approvals from the Brazzaville Watcher Group, Procurement Team, and Contracting Officers. No specific pricing is listed, and the total funding amount is currently shown as $0.00 USD, though an allotment document suggests a budget of $169,500.00.

Requisition Comments
Charles Koumba, 06/30/2025:
1. This system has been running for 16 years and has shown signs of operational inefficiency in recent years. This is reported in the Annual Facility Condition Survey (AFCS 2024).
2. The last TAB was conducted in 2008. In recent years, despite having adequate readings on key operational parameters (such as chilled water supply temperature, fan static pressure, and VFD speed values), the cooling assets have been underperforming. Over the last three years, these cooling units have struggled to maintain proper functionality to reach the supply air temperature setpoints. These issues have been verified during the last two BAS (Building Automation System) Preventive Maintenance sessions performed by Alabama Controls. Recommendations from these PM sessions have highlighted the need for both air and hydronic TAB to ensure the systems operate optimally.
3. Two contractors can be contacted for RFQ:
