NIST Requirements Upgrade HVAC controller software

I. Background The Dimensional Metrology Group (DMG) performs many critical calibrations each year, and develops documentary standards for evaluating dimensional measurement systems. To achieve these goals the need to maintain the environmental conditions in the laboratories at precise settings for temperature and humidity are required. As these systems age they need to be replaced or upgraded to maintain reliable operation, or due to failure.

II. Scope The DMG requires an upgrade to the HVAC controller software and computers in three (3) NIST laboratories, and services to repair or replace the humidifier system in the Letiz CMM lab (BLDG 220/A12) and the API Lab (BLDG 220/B05). Within these labs they need new computers with specialized software and hardware to interface and control the existing heating, ventilation and air conditioning (HVAC) systems.

III. Minimum Requirements The products shall meet or exceed the minimum requirements identified below. Selection of automation application to be used shall be either Alerton, Andover, Siemens, Automated Logic. All devices must be new. Used or remanufactured equipment will not be considered for award. Experimental, prototype, or custom items will not be considered. The use of “gray market” components not authorized for sale in the U.S. by the Contractor is not acceptable. All line items shall be shipped in the original manufacturer’s packaging and include all original documentation and software, when applicable.
