This is a 100% small business set-aside combined synopsis/solicitation for a firm fixed-price purchase order to replace a server room mini split HVAC unit at USCG Base Charleston, 1050 Register St, N. Charleston, SC 29405. The evaluation will be Lowest Price Technically Acceptable (LPTA), with the contract awarded in its entirety to a single offeror on an all-or-nothing basis. Interested vendors must be registered with an active UEI in SAM.gov and submit a quote via email that includes a detailed labor/material cost breakdown, a technical proposal, and the SF-1449. A site visit is highly encouraged and must be scheduled by emailing the point of contact, though failure to visit does not relieve bidders from accurately estimating costs. All applicable attachments, including the Statement of Work and wage determination, must be reviewed, and questions must be submitted in writing.
