The National Weather Service seeks quotes for replacing the air conditioning system at its Weather Service Office in Hilo, Hawaii, at 121 Ailolo Street. Performance must be completed within 90 days from award, and the contract is a small business set-aside firm-fixed-price purchase order with net 30 payment terms. The amendment clarifies that installer certifications from a designated HVAC subcontractor are acceptable, R-454B refrigerant is allowed, false columns are plywood with a specified paint code, and existing units use gravity condensate drains. Dedicated breakers and service disconnects are already in place, and weather-related schedule extensions may be granted by the government. A site visit is highly recommended but not required.
