USAF - Hitachi Fan Coil Installation, San Antonio, TX - MRAS

The United States Air Force (USAF), in collaboration with the General Services Administration (GSA), is engaging in market research to assess capabilities for a specific installation project at Joint Base San Antonio, Fort Sam Houston, Texas. The overall goal of this initiative is to enhance the operational efficiency of Building 2261 by installing additional HVAC components. This project is part of a broader effort to maintain and improve infrastructure within USAF facilities, ensuring they meet modern standards for energy efficiency and comfort.

The work being requested involves the installation of four Hitachi Variable Refrigerant Flow (VRF) fan coil units (FCUs) within Building 2261. The contractor will be responsible for providing all necessary supervision, transportation, equipment, and materials to complete this task. The specific locations within the building include several elevator mechanical rooms and a secure SIPR room. This installation will require careful coordination to ensure that all systems are integrated seamlessly with existing infrastructure while minimizing disruptions to ongoing operations.

Key deliverables for this project include the demolition and removal of any existing fan coil units that remain in place, followed by the installation of new wall-mounted indoor units complete with controllers and condensate pumps as specified by Hitachi standards. Additionally, contractors will need to install refrigerant lines using copper y-joints to balance flow across the system effectively. System integration tasks will involve utilizing existing electrical services while ensuring proper communication between new units and the central control panel through updated communication cables.

Upon completion of installation tasks, contractors must conduct thorough testing and commissioning processes. This includes pressurizing systems for leak checks, evacuating connected lines, adjusting refrigerant charges, performing factory-authorized start-ups, and providing operator instruction as necessary. A comprehensive inspection process will ensure all systems function according to manufacturer specifications before final acceptance. Furthermore, contractors must adhere to scheduling requirements that prioritize minimal disruption during secured area operations while also complying with safety regulations set forth by OSHA and Air Force guidelines.
