HVAC Preventive Maintenance Services at the Chief of Mission Residence in Singapore

Amendment 0002 to RFP 19SN1026R0007 has been issued by the U.S. Department of State, U.S. Embassy Singapore, to solicit contractor proposals for HVAC preventive maintenance services at the Chief of Mission Residence in Singapore. This amendment, effective March 2, 2026, revises Section J by updating Exhibit G (Equipment Summary) to include two additional HVAC units that were not part of the original solicitation. The modification adds a Daikin FTKM50PVM indoor unit and corresponding RKM50PVMG outdoor unit, both located in the Wine Storage Room. The updated equipment list provides comprehensive details across the 1st and 2nd floors of the facility, including equipment brand, model, serial numbers, cooling capacity in BTUs, commissioning dates, and refrigerant specifications. All other terms and conditions of the original RFP remain unchanged.

The primary objective of this amendment is to ensure that contractor proposals accurately reflect the complete scope of HVAC equipment requiring preventive maintenance services at the residence. Offerors must base their technical proposals and pricing on the revised Exhibit G, which now includes the Wine Storage Room cooling units in addition to all previously listed equipment. The proposal submission deadline has been extended to March 9, 2026, at 1630 hours Singapore Time, and contractors are required to acknowledge receipt of Amendment 0002 in their submissions. There are no set-asides specified for this opportunity, meaning it is open to all eligible contractors classified under NAICS 238220 (Plumbing, Heating, and Air-Conditioning Contractors) and PSC J041 (Maintenance/Repair/Rebuild of Refrigeration and Air Conditioning Equipment). Interested contractors should review the amended solicitation materials immediately to ensure compliance with all submission requirements and deadlines.
