Scope of Work

Mini-Split HVAC System Installation Project Location:

John Day Fossil Beds National Monument – Maintenance Shop 32651 Highway 19, Kimberly, OR 97848

Project Summary Procure and install a high-performance, cold-climate mini-split heat pump system to serve four rooms within the maintenance facility. The system must provide efficient and reliable heating and cooling year-round in an environment with sub-zero winter temperatures. The contractor shall provide all labor, equipment, and materials required for installation, testing, and commissioning of the new system.

3. Coordinate mobilization and work schedule with the Contracting Officer’s Representative

(COR).

4. Store all materials in protected, dry storage areas until immediately prior to installation.

5. Inspect all delivered materials for damage or defects before installation.

6. Install new HVAC systems including condensate and refrigerant lines, line set trim, rough-in, trim out, and testing.

7. Provide jobsite cleanup daily and complete final site cleanup and demobilization after project completion. Remove all tools, materials, debris, and waste generated by the installation process. Sweep and wipe down work areas to ensure cleanliness. Dispose of all installation-related waste materials in accordance with local regulations and park requirements.

8. Install heat pump systems per IBC 2018, IMC 2018, IECC 2018, IPC 2018, NESC 2017.

9. Install exterior condenser on a UV-resistant, weatherproof equipment pad (e.g., DiversiTech

E-Lite or equal). Rated to support at least 250 lbs. Installation: pad should be placed on compacted level soil, gravel, or harder surfaces. Three-inch minimum pad height required.

10. All materials to be contractor-furnished from outside the park.

11. Government provides electrical service from panel to single disconnect located. The government furnished disconnect location designated by included drawing.
