1.0 BACKGROUND

Dry Tortugas National Park is located 68 miles from Key West, Florida, located in the Gulf of Mexico. The park is comprised mainly of open ocean and coral reefs with seven small islands of which two islands have facilities. Garden Key is home to Fort Jefferson and is the main point of visitation and park operations. There are no commercial services in the park such as restaurants, retail, or lodging.

The existing HVAC inventory, currently consisting of twenty-three (23) mini split systems, have surpassed their intended service life and are no longer functioning efficiently. The purpose of this requirement is to provide continuous preventive maintenance, corrective maintenance, repair, and technical support for the Park's HVAC systems while systematically replacing aging and deficient equipment during the Base Period and applicable option periods.

Under this contract, contractors will replace eight (8) deficient HVAC systems during the base year, while providing regularly scheduled maintenance, service, and repair for all twenty-three

(23) systems. In option year one (1), the contractor will replace an additional eight (8) systems while performing ongoing service, maintenance, and repair of all twenty-three (23) systems. In Option Year Two (2) through Option Year Four (4), following replacement of all identified systems to high-efficiency units of the same manufacturer as described herein, and including a new system in Quarters Two (2), the contractor will provide ongoing maintenance, service, and repair of twenty-four (24) systems throughout the duration of the contract to ensure optimal operations and reliability. The Contractor shall maintain all systems that remain operational during each contract period, including existing equipment awaiting scheduled replacement and newly installed replacement equipment.

Non-functional HVAC systems that cannot be repaired and require replacement out of sequence shall be replaced as described herein (see Section 14: Technical Specifications).

The National Park Service (NPS) is requesting to contract these duties out to a non-NPS contractor who would be responsible for completing these tasks. Services shall be provided in strict compliance with the terms, specifications, conditions, and provisions contained within this Statement of Work (SOW).

2.0 OBJECTIVES

The NPS seeks to hire a contractor to furnish all qualified labor, supervision, tools, diagnostic equipment, replacement parts, materials, supplies, transportation, and other resources necessary to maintain the HVAC systems in a safe, reliable, and fully operational condition, except for those items expressly identified as Government-furnished herein (see Section 12: Government Furnished Property).

3.0 PLACE OF PERFORMANCE

The work of this contract will take place at Fort Jefferson on Garden Key. Garden Key is accessible via seaplane, commercial ferry, or personal vessel.

Park housing is a shared living situation in a bunkhouse setting. Housing rates are $45/person/night to be paid to the Park at the https://www.ipp.gov/ mailto:ippgroup@bos.frb.org end of each month of occupation.

12.2.1 Installation: For Government estimating and workload planning purposes, replacement of eight (8) mini-split HVAC systems is estimated to require a crew of three (3) qualified HVAC technicians for approximately five (5) eight-hour workdays on-site, equivalent to approximately 120 technician labor-hours.

• The estimated effort includes removal of existing indoor and outdoor units; installation of replacement equipment; connection or modification of existing refrigerant piping, condensate drainage, electrical connections, and controls as necessary for a like-for-like replacement; evacuation, pressure and leak testing; refrigerant charging as required; startup and commissioning; operational testing;

cleanup; and preparation of required installation and service documentation.

• This estimate assumes existing electrical service, mounting locations, refrigerant-line routes, and other supporting infrastructure are suitable for reuse and that no significant unforeseen conditions are encountered. Major electrical upgrades, structural modifications, extensive replacement of refrigerant piping, hazardous-material abatement, or other substantial corrective work shall be considered outside this estimate.

12.2.2 Service/Preventative Maintenance: For Government estimating and workload planning purposes, routine preventive maintenance of the 23 mini-split HVAC systems is estimated to require a two-person HVAC technician crew for approximately three (3) eight-hour workdays per scheduled maintenance visit, equivalent to approximately 48 technician labor-hours.

This estimate assumes routine inspection, cleaning, testing, servicing, minor adjustments, and maintenance documentation and does not include significant corrective repairs, equipment replacement, or other work requiring separate authorization. Mobilization and transportation to and from Dry Tortugas National Park shall be accounted for separately from on-site preventive maintenance labor.
