Amendment 0001

The purpose of this amendment is to provide

Responses to Questions received.

The following questions and or clarifications requests were received from various interested parties. All questions and clarifications have been consolidated. Questions are denoted by “Q” and the response is denoted by “R.”

Q1: Prime/Subcontractor Teaming and

Manufacturer Authorization: The Addendum to RFO

52.212-1, Section 6, Item 2 requires the

"Quoter" to provide written documentation from the air conditioning manufacturer stating the

Quoter’s authorization to install the equipment and eligibility to obtain the manufacturer's warranty. Additionally, SOW Section 3.4 requires the "contractor" to be certified by the AC manufacturer. Under a

Prime/Subcontractor teaming structure where the

Prime provides complete administrative, compliance, and contract management oversight, will the Government accept the manufacturer authorization, certifications, and training credentials of our designated technical HVAC subcontractor to fully satisfy these requirements?

R1: Yes, the designated HVAC subcontractor / installers certifications are acceptable.

Q2: Refrigerant Compatibility and EPA Phase-Out

Compliance: SOW Section 2.2(a) specifies the preferred equipment as the Mitsubishi GX Series

MUZ-GX30NL/MSZ-GX30NL (or equivalent). The

Mitsubishi GX Series operates natively on

R-454B refrigerant, yet the subsequent SOW requirement states that the "Refrigerant shall be R-410A or other that is commonly acceptable". Given the ongoing Federal EPA phase-out of R-410A in new residential and light commercial split-system air conditioners, will the Government clarify if R-454B is acceptable and preferred for the new units to ensure long-term regulatory compliance and maximize system efficiency?

R2: R454-B refrigerant is acceptable.

Q3: Structural and Architectural Details for

False Columns: SOW Section 2.2(b) notes that all refrigerant lines must run through exterior chases in false columns, requiring the contractor to open, re-enclose, and repair these columns to match their original condition. Are architectural drawings or structural detail sheets available for these false columns? Additionally, can the Government provide any specific material, stucco, or paint matching requirements to ensure repairs meet the facility's structural and aesthetic standards?

R3: No architectural drawings are available for the false columns which are constructed of plywood. See picture in solicitation. Paint code is ECC-53-1 BEHR Mown Hay, exterior, semi gloss.

Q4: Existing Electrical Infrastructure

Capacity: SOW Section 2.2 requires the contractor to verify the existing electrical service to ensure a proper and safe installation of the new AC units. To prevent latent site challenges, can the Government confirm if the existing electrical panel has sufficient spare breaker spaces and rated amperage to support the dual 208V, 60Hz, single-phase 30,000 BTU systems without requiring an electrical service or panel upgrade? If an upgrade is determined necessary, will that be treated as a Government responsibility or within the contractor's scope?

R4: There are dedicated breakers for the existing split unit ACs in the circuit breaker panel. There are service disconnect boxes for each unit outside. See picture in solicitation.

Q5: Condensate Management and Drain

Configuration: SOW Section 2.2(b) states that the contractor must provide and install a condensate pump with a high-water level switch

"(if necessary)". To help offerors construct precise and equitable pricing, can the

Government clarify if the existing Sanyo SOW units utilize gravity condensate drains, or if they are currently equipped with functional condensate pumps?

R5: The existing Sanyo ACs utilize a gravity condensate drain.

Q6: Weather Delays and Period of Performance

Adjustments: SOW Section 3.1 states that installations may not be permitted during upcoming weather events, and Section 4.0 establishes a strict 90-day Period of

Performance. Given that Hilo, Hawaii experiences frequent high-rainfall weather, if severe weather events or operational stand-downs are mandated by the Technical Point of Contact (TPOC), will the Government grant excusable, non-compensable schedule extensions in accordance with FAR 52.212-4(f)?

R6: Yes
