Questions & Answers / Clarifications

This document contains responses from the National Park Service (NPS) to a Request for Information (RFI) regarding HVAC equipment for the Kalaupapa National Historical Park (KALA), Molokai. It clarifies details for potential bidders.

• Personnel: The NPS confirms that a single Job Superintendent can perform multiple roles (Project Manager, QC Manager, Safety Manager, etc.) on small, non-complex projects.
• Condensate Drainage: There are no existing drywells. Condensate water from new HVAC units will be piped to the exterior. The NPS will construct the drywells after contract construction is complete.
• HVAC Equipment Delivery: The NPS intends for equipment to arrive on the August 2026 barge. If it misses this barge, the project will be rescheduled for August 2027, with a contract modification issued for additional time and potential storage.
• Project Type: This is a design-bid-build project, not design-build. As-built drawings are provided, and the park electrician has confirmed sufficient power capacity in existing panels; no new electrical panels are anticipated.
• Power Source: HVAC equipment will be connected to existing electrical panels that are powered by a standby generator via an automatic transfer switch. It will not be wired directly to the generator.
• Buy American Act (BAA): A general BAA waiver has been issued for ductless HVAC mini-splits as no units meeting the required size and capacity are manufactured in the U.S. A specific waiver is not required. If alternative products are proposed, they must meet or exceed the salient characteristics of the specified Mitsubishi models, be from the same manufacturer, use R-454b refrigerant, and have readily available parts and service on Oahu.

This RFI clarifies key aspects of the project, including personnel requirements, site conditions, delivery logistics, electrical infrastructure, and material sourcing (BAA). Bidders should consider these clarifications when preparing their proposals. The document also references specific sections of the specifications (e.g., Section 01 11 00, PART 1.2.C.1 and Section 01 33 23, PART 1.4.F) for further detail.
