GHMOF Bard AC Unit

The document is a Request for Quotation (RFQ) issued by NASA for the replacement of a failed air conditioning unit in the Global Hawk Mobile Operation Facility (GHMOF). The primary objective is to install a compatible wall-mount Bard air conditioning system that meets specific requirements, including maintaining existing mounting and electrical configurations. The contract is set aside for small businesses, with quotes due by March 5, 2025, and delivery required by April 1, 2025. Offerors must adhere to various federal provisions regarding telecommunications, certifications, and representations, emphasizing compliance with federal regulations and proper registration in the System for Award Management (SAM). The document outlines the tasks required of the contractor, including installation, servicing, and operational testing of the new unit, while specifying performance and procurement conditions necessary for evaluation. This RFQ illustrates NASA’s commitment to maintaining operational efficiency and safety for its unmanned aircraft operations.

The document outlines the Statement of Work for the NASA Sky Range project's requirement to replace a failed air conditioning unit in the Global Hawk Mobil Operation Facility (GHMOF). The GHMOF is a transportable facility that commands and controls unmanned Global Hawk aircraft, equipped with essential electronic systems that necessitate cooling due to heat generation. The project aims to install a new wall mount Bard air conditioning unit, maintaining the same configuration and specifications as the failed unit. Key tasks include mounting the new A/C unit, utilizing existing ductwork and wiring, connecting to the power supply, and testing the system's operation. The required HVAC unit specifications include a 5-ton heat pump operating on a 230V, 3-phase system without electric heat or a vent package. The project is set to occur at NASA's Armstrong Flight Research Center in Edwards, California, with a delivery deadline of April 1, 2025. This work is essential for ensuring the operational efficiency and reliability of the GHMOF during its deployment.

The NASA Global Hawk Mobile Ground Control Facility (GHMOF) outlines specifications for the installation of Bard air conditioning units in its trailer. The project requires two 6-ton Bard air conditioning units, each featuring a heating capacity of 10 kW and capable of delivering 51,500 BTUH cooling at an ambient temperature of 130°F. Each unit utilizes R-410A refrigerant, has a maximum power draw of 12.2 kW, and operates on a 120/208 VAC, 3-phase, 60 Hz electrical system. The air conditioners are designed for high air circulation with a capacity of 1600 CFM at a static pressure of 0.25 inches. Each unit weighs approximately 575 pounds. The document serves as a technical specification for prospective contractors responding to a government RFP for this installation, outlining essential requirements for compliance and performance standards in line with NASA's operational needs.

This document outlines requirements for replacing a failed HVAC unit, specifically a Bard model. It confirms the necessity of a lift gate for delivery and details the modifications in size of the new unit, which will feature a larger condenser coil and increased depth, while maintaining compatibility with existing framing and duct openings. To ensure an accurate replacement, the contractor requires the model number and serial number of the existing unit. Additional specifications regarding the controls of the current system can be found in the attached HVAC slide. The focus of this document is to facilitate the procurement process for completing the HVAC replacement in line with government standards, ensuring functionality and consistency with existing infrastructure.
