This is a preliminary market research notice, not a solicitation for bids. The requirement is to replace a 17.5-ton rooftop package cooling unit and its appurtenances at the Visitor Center of the War in the Pacific National Historical Park in Guam. The work includes removing the old unit, preparing the pad, and installing and commissioning a new, specified Carrier model PCU. The notice seeks to gauge the interest and capabilities of qualified small businesses within specific socio-economic categories for a potential Firm Fixed-Price contract. Responses from vendors should include company details, relevant project experience, and business size/socio-economic status.
