PROJECT DESCRIPTION / SUMMARY:

The primary work of this project includes but is not limited to inspect and repair as per the original manufacture procedures and instructions of a commercial building automated HVAC system . The commercial HVAC system located at the Heritage Center in Gardiner Montana. The HVAC system is a Heat Pump, humidifier/dehumidifier, heated water system with air handler. The project includes a cooler tower upgrade, humidification system upgrade, Operator front end access to the Building Automation System, (BAS new web server), and heat pump upgrades. The work shall include as an option line, the excavation, and removal of an underground water storage heat transfer tank.

The contractor shall provide all personnel, supplies, supervision, tools, materials, equipment, transportation and other items and non-personal services necessary to provide HVAC services in accordance with this Performance Work Statement (PWS) except as those items specified as government furnished property and services. The contractor shall perform to the standards in the contract as well as all local, state, and federal regulations.

All work for the duration of the contract shall be performed by trained technicians.

1.0 OBJECTIVES:

The objective of this contract is to inspect and repair the HVAC system , provide full front-end access to the BAS system and repair, upgrade of nonfunctioning components.

The awarded contractor shall inspect, repair, replace and perform initial startup (commissioning is required)

2.0 BACKGROUND:

The HVAC system is greater than 20 years old with no current system upgrades. Components are failing and front-end access requires a new web server for NPS technician to access the controls. The building is critical to the preservation of YNP artifacts and requires numerous components to function properly. The HVAC system includes Air handlers, humidity controllers and heat exchangers/pumps.

3.0 SPECIFIC WORK / TASKS:

1. Humidification system inoperative (5 each unit)

2. NPS service technicians do not have front end access to MTI proprietary system. The project requires the install of a new Web Server with nonproprietary characteristics.

3. Inspection of the BAS system (building automation system) to move from a proprietary system to a non-proprietary fully automated system with full remote access by NPS service technicians (install a new web server)

4. Web Server Front End (Qty 1)

5. Tridium Niagara web server ▪ Includes 5 years of software update subscription

6. Install a Graphics, trends & alarms

7. The new BAS system shall include an open license for non-proprietary access On-site training for the web server with a 1-year warranty

8. Provide an inspection report of all components of the HVAC system deficiencies

9. Relocate cooling tower lines (supply and return lines). The old lines shall be rerouted above grade and this task may require concrete boring.

10. All exterior piping shall be insulated in kind and equipped with thermal protection (heat tape)

Follow manufacturers recommendations the awarded contractor shall perform a service on the HVAC system.
