Statement of Work: HVAC Replacement in Death Valley National Park

PMIS 342948

National Park Service

Death Valley National Park

Inyo County, California

1. Background

a. Project Goal: The goal of this project is to replace failed or failing heating, ventilation, and air conditioning (HVAC), which, herein, includes evaporative coolers, at Death Valley National Park with consistent equipment that will provide heating and cooling for the comfort and safety of employees, residential tenants, and visitors.

b. Location: Death Valley National Park is approximately 3.4 million acres in Eastern California and Southern Nevada. Furnace Creek, where the Park headquarters is, is on California Highway 190 (CA-190), about 120 miles west of Las Vegas, Nevada and 300 Miles northeast of Los Angeles, California. The project includes work at Furnace Creek, Cow Creek, 3 miles west of Furnace Creek on CA-190, and Stovepipe Wells Village, 25 miles west of Furnace Creek on CA-190. The project area includes all the Park’s developed areas, including, but not limited, to Furnace Creek, Cow Creek, Stovepipe Wells, Emigrant, Grapevine, and Scotty’s Castle.

c. Issues: Death Valley National Park is the hottest place on Earth. In July, the hottest month ever recorded, Death Valley had 9 consecutive days over 125°F, multiple thunderstorms, and a more-than-three-day power outage. Extreme weather events and unstable power have caused numerous mechanical system failures in June and July of 2024. This project will replace units that are beyond their useful life and/or damaged beyond repair.

d. Objective: Damaged HVAC systems in 15 facilities shall be replaced in Death Valley National Park. This will require ancillary electrical and plumbing work to connect HVAC units. Old equipment shall be removed and disposed or recycled at appropriately licensed facilities.

e. Hazardous Materials: Work is not expected to impact asbestos containing materials.

However, asbestos containing materials are present in some of the facilities. A good faith survey of asbestos containing materials is provided to ensure that asbestos is not disturbed by the work. Facilities may also have lead-based or lead-containing paint or other hazardous materials that are not expected to be impacted. The Contractor shall use industry best practices to minimize employee and tenant exposure to hazardous materials.

f. Energy Efficiency: All units shall be Energy Star rated with a SEER2 rating not less than

16. Gas furnaces, if installed, shall be 96% efficient and compatible with the fuel supply at the facility.

2. Project Tasks

a. The Contractor shall perform the following tasks.

i. Remove existing equipment to be replaced, including any existing mounting hardware, appurtenances, and associated components.

iii. Restore exterior siding/roofing and interior walls/ceilings of facilities where equipment is removed, installed, or replaced with equipment of different size, which shall include filling holes in walls and finishes, repairing damaged finishes to include texturing, painting, or similar, to create a uniform finish in, around, and adjacent to the work.

iv. Ensure all penetrations are adequately sealed to prevent loss of conditioned air and infiltration of outside pests, air, and debris.

v. Recycle or dispose of removed equipment, material, and construction debris at an appropriately permitted facility outside the Park according to applicable laws.

Provide the approximate tonnage of waste disposed and material recycled.

vi. Perform vent-testing procedures in accordance to American National Standard ANSI Z21.47 to assure proper venting.

vii. Install vent/flue pipe at proper vent size and connectors.

viii. Install air conditioning coils on top of furnaces. Ensure that units are mounted so that proper draining of condensation can occur.

ix. Install drain pan, trap, and lines per the manufacturer’s recommended configuration.

x. Where concrete footings are inadequate, install concrete pads in place per manufacturer’s recommended dimensions. Adjustable stands may be substituted for concrete footings where acceptable by code and manufacturer’s recommendations. Stands shall have sun and rain protection where it will not interfere with the operation of the equipment. Location of pads, stands, and equipment when not replaced in-kind shall be defined by the contractor and approved by the COR prior to installation.

xi. Install new electrical service where required. Electrical service lines shall be installed to conceal them as much as possible in attic, crawls spaces, and walls.

Electrical service lines may be installed on the exterior north wall of the Cow Creek Ranger Station.

xii. Install copper, or approved equal, refrigerant lines from air condensers (or similar) to air conditioning coils (or similar). Line sets shall be insulated and installed to conceal them as much as possible in attic, crawl spaces, and walls.

Where line sets are not concealed, they shall be covered with line set covers suitable for the location, including color and sunlight resistance.

xiii. Install duct transitions from new HVAC units to existing building ducting.

xiv. Install new thermostat at existing thermostat location. If existing thermostat wires are incompatible with the new equipment, required wiring shall be installed and traced through walls for the new thermostat to function as intended by manufacturer.

xv. Paint and repair any unfinished wall/ceiling/floor interior/exterior surfaces created by replacing HVAC units this may require caulk, flashing, transitions, or painted wood trim.

xvi. All installation shall be in accordance with manufacturer specifications.

xvii. Test newly installed HVAC system by performing manufacture gas pressure test, temperature rise test, AC leak test, heating and cooling test, and any other tests recommended by the manufacturer or industry standards.

1. 129 Skyline Drive

2. 1 Canyon View Court

3. Cow Creek 51

4. 222A-F Skyline Drive

5. 120 Skyline Drive

The PCE allows for the following

• in-kind replacement of HVAC thermostat, which may include upgraded digital components and software;

• repair or in-kind replacement of minor physical unit components (ductwork, pipes, valves, switches, etc.);

• installation of copper piping through existing exterior penetration that runs internally in attic crawl space to each power head;

• repair or in-kind replacement of major components and systems (e.g.

swamp coolers, condensers, compressors, motors, furnaces);

• repair or in-kind replacement of concrete pads for exterior system components; pads must be in the same location and same-sized;

• replacement of coolant or refrigerant;

• repair of electric systems within or associated with the unit(s).

The PCE also covers minor interior access needs in the event some components (e.g. refrigeration lines) within buildings need to be replaced and are blocked by a wall. In these cases, the interior walls may need to have small openings cut for access to the system. The PCE covers impacts to the walls that would be a maximum of 6'' by 6'' cuts and which would be repaired and repainted or covered to match existing colors and textures. In the Mission 66 buildings, the walls are wood frame with gypsum board. The CCC buildings with HVAC systems have non-historic interior walls, typically also made out of gypsum board, to provide space for utilities.

ii. Some of the project occurs in park housing area. Contractor shall be respectful of the tenants of the housing area and confine workspace and areas to not impede on tenants.
