GENERAL REQUIREMENTS

SUMMARY OF WORK

WORK COVERED BY CONTRACT DOCUMENTS

A. General: All work outlined below will be performed under a single contract.

B. Project Location: This project is located at 44150 District Office LN, Davenport, WA 99122

Housing unit 1004.

C. Project Background: Housing unit 1004 is a required occupancy unit that houses LE rangers year-round. The current HVAC system consists of an electric RHEEM air handler model

#RHQA 1620 T manufactured in 1979, and a TRANE XR11 heat pump manufactured in

2003. This unit has a REHAB project, and the HVAC system needs replaced. Replacement of this unit will make the facility more energy efficient, and the reliability of this unit will negate future repair bills in the coming years due to the age of current unit.

D. Project Scope of Work: The Work consists of the following:

1. This project will replace the existing HVAC unit with equal to or better than the existing HVAC unit. Manufacture make and model of new unit to be equal to or better than existing unit. All existing ducting, and all associated components must be inspected by contractor for compatibility with the replacement HVAC unit’s manufacturer specifications.

2. Provide the National Park Service with cost and energy efficient HVAC system that is compatible with existing ducting and electrical components. All needed alterations to ducting and electrical shall completed by contractor. Contractor must install HVAC unit, ducting and all other components with as few disruptions or down time of current system to minimize impacts to park operations.

3. The Contractor is to provide all labor, equipment and materials unless otherwise stated in this scope of work. The contractor is responsible for all costs associated with this project, including all travel, per-diem, and the disposal if any waste generated by this project. A staging area will be determined during the preconstruction meeting at the work site. Electrical power, water and restrooms are available.

4. Work shall include but is not limited to:

5. Mobilization and Cleanup; a. All refrigerant will be disposed of following the state of

Washington environmental regulations and receipts or proof of proper disposal is required.

6. Remove and disposal of existing unit and its product specific parts.

7. Prior inspection by contractor of all ducting, electrical and all other components to determine compatibility with the replacement unit and must verify installation and operations in accordance with manufacturer specifications through testing and documentation. Must provide test results and operation and maintenance manuals to

Lake Roosevelt National Recreation Area for park records.

8. Contractor will provide submittals and perform alterations to ducting, electrical and all other components if required to meet manufacturer specifications to insure complete functionality.

9. Determine heating and cooling requirements for the size and uniqueness of the building

(considering ventilation needs, size of building, windows, insulation) Provide proof that the system will deliver specified efficiency and conduct load calculation for proper equipment selection.

Install replacement HVAC and air handling unit at current exterior location to manufacturer specifications.

10. Measure and document airflow

11. Test existing line sets for reuse or replace if leaks or defects are present.

12. Measure and document refrigerant charge

13. Modify or install new electrical service to fan, coils or air handler units if none exists including installation of new breakers labeled at associated breaker panel box. All electric work will follow manufacturer’s specifications and Washington State Electrical

Codes e.g. wire gauge, breaker amperage, power supply, etc.

14. Install new thermostats that meet manufacturer specifications, test, and submit results.

15. Assure PVC or approved drain lines will be installed to manufacture specifications and drain away from existing structure.

16. Provide as-builts and operations and maintenance manuals

Contractor will provide lump sum pricing.
