Amendment No. 0001 to RFQ 19KS7026Q0040 Geothermal HVAC Unit Replacement

The Department of State seeks geothermal HVAC unit replacement at its Seoul, South Korea facility, with proposals due August 13 under Amendment No. 0001 to RFQ 19KS7026Q0040.

The amendment clarifies two critical technical requirements. Contractors must possess extensive experience specifically with geothermal HVAC systems, not general HVAC replacement experience, to integrate new equipment with existing geothermal infrastructure and maintain technical competency during the mandatory one-year warranty period. The installation site operates on single-phase, 3-wire electrical power incapable of supporting 380V. Contractors are explicitly prohibited from converting the power supply to 380V through additional equipment installation, as achieving 380V requires a 3-phase supply directly from the utility provider, which is not feasible within the current project infrastructure scope.

The NAICS code is 236118, Residential Remodelers. The PSC code is Z1FA, Maintenance of Family Housing Facilities. No set-aside applies.
