Bedford, MA 01730 STATEMENT OF WORK Boiler Plant Burners, Controls, Instruments, and Data Management Inspection, Safety Device Testing and Calibration General Scope of Work 1. Semi-Annual Calibrations of Boiler Plant Controls and Instrumentation 2. Semi-Annual Combustion Testing of Boilers 3. Semi-annual Safety Device Testing 4. Semi-Annual Calibrations of Boiler Plant Controls and Instrumentation. 5. Annual Boiler Internal and External inspections A. OVERVIEW 1. Contractor shall provide all labor, tools, testing equipment and supplies required for semi-annual calibrations of Boiler plant controls and instrumentation for three boilers located in Building #22, two boilers in Building #70, and other plant equipment. 2. Contractor shall ensure all work is in accordance with the procedures outlined in VHA Boiler and Associated Plant Safety Device Testing Manual Eighth Edition, or the most current edition. 3. Contractor must have a laptop computer and required software to plug into and back-up all settings in the PCCIII controls and provide a back-up flash drive to Plant Supervisor. 4. Contractor will not be accessing any sensitive VA Information Systems, these are boiler controls only. Control devices will include but are not limited to the following: Preferred Instruments, CB Hawk, Foxboro, Yokogawa, Siemens, and Johnson Controls. 5. Contractor shall also supply to customer, calibration reports for each piece of equipment, indicating date, settings, pass/fail, technical data, and name of technician performing calibrations. 6. Contractor will provide a list of line items that require parts/replacement, and the costs required to repair/replace those items. Additional work beyond the scope of this contract, requires approval from the Contracting Officer. See attached list of controls and instrumentation to be calibrated. B. CALIBRATION The following is a list of devices that will require calibration: 1. Plant Master PCIII Outside air temp Plant steam flow Distribution steam flow Plant demand Steam header press Hi/Lo and alarms Oil pressure transmitter and alarms Propane pilot gas transmitter and alarms Main gas pressure transmitter and alarms Control air pressure transmitter and alarms Low main gas pressure alarm High main gas pressure alarm Explosive gas and carbon monoxide detection system 2. DA PCIII High oil header press alarm Low oil header press alarm DA steam PSI DA temp DA level High DA level alarm Low DA level alarm Cond PCIII: Condensate tank level Condensate tank high level alarm Condensate tank low level alarm Condensate tank temp Condensate tank make-up valve 3. Hawk Controllers Boilers, 1, 2, and 3 Plant demand Boiler demand Firing rate Steam flow Economizer flue temp-in 4. #1 and #2 Draft PCIII Oxygen transmitter Damper % Outlet temp Jackshaft position Efficiency 5. #1 and #2 Fuel Flow PCIII Boiler gas flow Boiler oil flow Flue gas temp monitor calibration Flue gas temp High and Low temp alarms 6. #1, #2, and #3 Feedwater Pump Variable Frequency Drive Units Note; there is a new DA Tank installed as of October 2024. Testing will reflect the new parameters required on the new system. C. SEMI-ANNUAL COMBUSTION TESTING OF BOILERS 1. Contractor will provide all labor and materials required to perform burner calibration on three (3) Cleaver Brooks CB700LE boilers. Each burner assembly will be inspected and adjusted to manufacturer s settings. Each boiler will be calibrated on gas and oil firing twice a year, approximately 6 months apart, as scheduled by the Maintenance and Operations Supervisor. 2. Contractor will provide burner calibration printouts for each pin on the gas and oil cams 20 on CB Hawk for all three boilers. Settings will be as close and safe as possible for max input for gas and oil firing at high fire as per the inputs listed on the boiler plate. 3. Contractor will calibrate the burners and not exceed the requirements of this facilities permit for emissions. Contractor will perform a smoke test on boilers. 4. Contractor is responsible for providing all tools and specialized equipment required to perform the work. D. ANNUAL BOILER INTERNAL/EXTERNAL INSPECTIONS Contractor shall perform 1 internal/external inspection, and 1 external inspection, on 3 Cleaver Brooks 700 LE fire tube boilers in the main boiler plant and 2 HB smith 14 section low pressure boilers in building 70. Internal inspections on all boilers will be performed once a year, 1 boiler at a time starting in the early spring until all boilers are completed. External inspections under pressure shall be performed in the early fall, to allow time to take a boiler down for any repairs needed a result of the inspection and prior to heating season. The inspector shall be a Commissioned National Board-Certified Inspector, and the inspections will be in compliance with National Board Inspection Code & ASME Code. The inspector is responsible for performing and adhering to his own Confined Space Entry Program in accordance with OSHA regulations when entering boilers. Contractor will provide all required inspections and certification documents for the inspections, along with color pictures of the internals and externals of the boilers. Contractor is responsible for providing all specialized tools and equipment required to perform the work. All inspections will be scheduled through the Boiler Plant Supervisor. D. SAFETY DEVICE TESTING 1. Contractor shall provide all labor, tools, and all testing equipment required to perform Semi-Annual Safety Device testing on three (3) Cleaver Brooks LE fire-tube boilers, and other plant equipment as identified in the VHA Boiler and Associated Plant Safety Device Testing Manual, Eighth Edition, or current edition. Testing shall be in accordance with the procedures outlined in VHA Boiler and Associated Plant Safety Device Testing Manual Eighth Edition or the most current edition. Testing manual will be available upon request. 2. Contractor shall provide a detailed report including a picture of each device as installed on the system and all other information required by the VHA Boiler and Associated Plant Safety Device Testing Manual, Eighth Edition or current edition shall be scheduled with the Boiler Plant Supervisor. 3. Contractor will furnish all tools, parts, and specialized equipment to accomplish this. 4. Devices tested shall include, but not be limited to the list below as changes may be made to the VHA Boiler and Associated Plant Safety Device Testing Manual Eighth Edition. High-steam pressure cut-out (recycle), High-steam pressure cut-out (non-recycle). Steam safety valves (raise boiler pressure until valves lift and reset). Check gas vent for leaks. High-gas fuel pressure cut-off. Low-gas fuel pressure cut-off. Gas fuel safety shut off valves proof of closure. Leak test fuel oil safety shut off valves. Check operation of Liquid Propane Gas pilot. Low-pilot gas pressure cut-out. Forced draft fan motor interlock. Forced draft fan damper wide open for purge. Boiler outlet damper wide open for purge.
