CHSC - Replace HVAC

The National Park Service Midwest Region is soliciting quotes for the replacement of HVAC systems at the Little Rock Central High School National Historic Site Visitor Center in Little Rock, Arkansas. The project specifically involves replacing Heat Pumps 5 & 6 located on a mezzanine level over two storage rooms, which requires removing existing lay-in ceilings, partially dismantling a cold-formed steel joist mezzanine to access the units, and reinstalling new grid and ceiling tiles with associated finishing work. Contractors must be registered in the System for Award Management (SAM) with current online representations and certifications, and are required to submit 3-5 past performance questionnaires for projects completed within the last five years. The solicitation includes comprehensive technical requirements for mechanical, electrical, and construction work, with detailed specifications for installation, safety protocols, and quality control measures. Quote submissions are due by July 1, 2025, at 8:00 AM CT, following an amendment that extended the original deadline of June 26, 2025.

This procurement is designated as a 100% set-aside for small businesses under NAICS code 238220 (Plumbing, Heating, and Air Conditioning Contractors) with a size standard of $19 million. The estimated project value ranges between $100,000 and $250,000, structured as a firm-fixed price contract with a performance period of 150 calendar days from the Notice to Proceed. The work involves replacing two specific vertical ground source heat pumps manufactured by Florida Heat Pump: an EC096-3VTC-F model (HP-5) with 2,615 CFM airflow and an EC120-3VTC-F model (HP-6) with 4,000 CFM airflow. Performance will take place at 2120 W Daisy L Gatson Bates Drive, Little Rock, Arkansas 72202, with work conducted primarily during normal business hours Monday through Friday from 7 AM to 5 PM.
