Statement of Work Boiler Management System Maintenance V04 529 Butler VA Medical Center

1. SCOPE AND OBJECTIVE

The Contractor shall provide inspection, calibration, testing and tuning of Boiler Management System and associated components, inspection of Feedwater-Deaerators, domestic hot water heaters. The Contractor shall be responsible for determining the number of personnel required to perform the duties specified in this Performance Work Statement (PWS). The Contractor will maintain and provide a record of all service activities performed. Services should be provided on-site at the Butler Veterans Affairs Medical Center (BVAMC) located at 325 New Castle Rd. Butler, PA 16001.

2. BACKGROUND

Boilers and boiler plants are essential to the operation of a VA medical facility by providing steam, space heating, hot water (for sanitation, food production and preparation, infection control), heat for process equipment, and a healthful environment for the delivery of healthcare.

The safety, reliability, efficiency, and longevity of equipment in the boiler plant are top priorities for the management at VA Butler. Boilers and feedwater deaerators are pressurized systems that contain steam and hot water. If they fail, they can do so catastrophically, resulting in injuries, fatalities, and significant property damage. Regular inspections conducted by experts are a vital component of a program designed to address these concerns.

The Butler VA is in need of a contract for inspection, calibration testing and tuning of Boiler Management System and all associated components, inspection of Feedwater-Deaerators, domestic hot water heaters. The contractor shall fulfill all requirements that are listed below and provide all incidentals and labor to keep the systems operational to meet the needs of the Butler VA. This Butler VA is requesting a one-year firm-fixed price IDIQ with 4 (four) additional option years.

3. REQUIREMENT OVERVIEW

3.1. Work Required

3.1.1. At VA Butler Healthcare, located at 325 New Castle Road, Butler, PA, annual internal and external inspections, combustion tuning and calibration, as well as relief valve service and safety device testing, shall be performed according to VA and manufacturer's recommendations for the following:

Summer DA

3.2. Vessel Deaerator NDT Weld Test/Inspection – Summary Requirements

3.2.1. Feedwater deaerator pressure vessel inspections must be scheduled during periods of low steam demand.

3.2.2. This inspection is due every 5 years and will only be required in 2030.

3.2.3. Coordinate the inspection schedule with the TPOC (Technical Point of Contact) so that VAMC can prepare the boilers and feedwater deaerators for the inspections in advance and have personnel available to monitor inspections.

3.2.4. The boiler and feedwater deaerators inspections shall comply with the guidelines in the current issue of the National Board Inspection Code, Part RB, in service inspection of Pressure-Retaining items and ASME Boiler and Pressure Vessel Code, Section VI and VII as applicable. In addition to those guidelines, the inspections shall comply with all VAMC requirements as listed in this document.

3.2.5. The contractor shall inspect and enter all the internal spaces of the boiler or feedwater deaerator and visually inspect all internal surfaces that can be accessed. Confined space entry person, attendant, and equipment is the responsibility of the contractor.

3.2.6. Health Safety Plan and confined space entry training certificates must be submitted for approval.

3.3. Hydronic Boilers – Summary Requirements

3.3.1. Using the control panel, enter the information mode and scroll down to view the flame signal. When the boiler is firing, the signal will be "yes" and when the boiler is not firing, the signal will be "no".

3.3.2. Test high-limit control by reducing setting below the operating temperature. Burner should shut off. After readjusting the thermostat, press the button to reset the switch.

3.3.3. Test operating temperature control by reducing temperature setting as necessary to check burner operation.
