Description

Statement of Work Inspection, Safety Device Testing and Calibration Boiler Plant Burners, Controls, Instruments, and Data Management Introduction: A. The Kansas City, VA Medical Center requires the semi-annual services for the inspection, testing and certification of all boiler safety devices on: The four, high pressure steam boilers, in the plant at Building 4. These boilers produce the steam to the Medical Center Main Campus. The six, outlying low-pressure hot water (hydronic) boilers used for heating and domestic hot water at Buildings 2 and 56. The safety device testing is a critical service for the Boilers at the Medical Center, so it is critical that the testing is completed within 14 calendar days of the 6-month pre-scheduled testing date provided by the Medical Center. There may be occasions where the Medical Center may extend the schedule for burners in limited service. Technicians performing the inspections shall be certified and credentialed Boiler Inspectors. . B. Boiler plant safety, reliability, efficiency, and equipment longevity are critical safety and property concerns of the Medical Center. Malfunctioning burners or controls can cause catastrophic events resulting in injuries and death and massive property damage. Inaccurate or inadequate data management and monitoring systems can fail to warn of unsafe or inefficient performance. Regular inspections, testing, and calibration by expert technicians are an essential part of a program to address these concerns. C. This Statement of Work describes the requirements for the inspection, testing and calibration of the boiler plant burners, burner management system, controls, instruments, gauges and transmitters by qualified technicians. This will include the 3 Hydronic Boilers at Building 2 and the 3 Hydronic Boilers at Building 56. Objective: The services we require are for semi-annual preventative maintenance services that includes the testing, inspection and certification for all the Boilers in the 3 buildings of the Medical Center s main campus. Key Deliverables: Inspection of 4 High Pressure Steam and 6 Hydronic Boilers and Safety Devices Testing of 4 High Pressure Steam and 6 Hydronic Boilers and Safety Devices Calibration of 4 High Pressure Steam and 6 Hydronic Boiler Safety Devices Inspection, Testing and Calibration Report, Including Certifications. Contractor will provide all tools, materials, labor, supervision and all specialized testing equipment needed to perform semi-annual testing, inspection and calibration on all boiler safety devices, Boiler Plant Burners, Controls, Instruments, and Data Management System. D. Attachment A shows the equipment inventory and includes the Boiler information along with the primary supporting equipment that is included in this contract. E. Appendix B, covers the inspections of the six, hydronic boilers at Buildings 2 and 56.; F. It is assumed as part of any boiler testing and inspections that whether a hot water boiler or steam boiler that repairs, adjustments or replacement of components may be required at additional cost. G. It is assumed as part of any gauge or transmitter testing and calibrations that whether a hot water boiler or steam boiler system that repairs, adjustments or replacement of components may be required at additional cost. Technician and Test equipment Qualifications: Technicians performing the testing and inspections on all the boilers at the Kansas City, VAMC, shall have completed at least a one-year trade school and have five consecutive documented years of successful experience in this field.

Report Requirements: A VA compliant test report will contain certification on the first page following the report cover page that includes the technicians name, signature, date and the name of the company performing the testing. Provide complete written report of the inspection fully describing all tests performed, all findings, and recommendations. The report shall have two sections. The first section will be in a table form that has four columns: a. The first column labeled FUNCTION did the device pass or fail. b. The second column labeled Device list the device number and description in accordance with the VHA Boiler Plant Safety Devices Testing Manual, 5th Edition. c. The third column labeled Deficiencies-Recommendations d. The fourth column labeled corrective actions list any corrective actions taken during the inspection. The second section shall be in paragraph/bulleted form and list each device individual in accordance to the VHA Boiler Plant Safety Devices Testing Manual, 5th Edition. In addition, the section must reference the correct Master Specification and Standard Detail for that device. 5.1. Condensate Storage Tank and Deaerator Tank. A. High Water Alarm Purpose: High water level may be an indication of condensate transfer pump failure that could lead to low water condition in the feedwater deaerator and in the boilers. There may be a failure of make-up water controls. Recommended set point: 4 inches below overflow level and 2/3 of tank height or as described in Safety Device Testing Manual, Fifth Edition. Potential hazards due to failure of high-water alarm: Feedwater deaerator running dry and, consequently, boiler feed pumps running dry will cause overheating and damage to pumps and potential for plant shut down. Failure of make-up water controls (in open position) could lead to significant cost from waste of water and condensate from the tank overflow if this occurs over a long period. Recommended type of device: Conductivity probe type switch. Float type switches have high failure rate in this application where they are exposed to flash steam that causes seals to harden and prevent float movement. Comments: Float type switches are not allowed for high water alarms. The VA recommended switch type is a conductivity probe type switch. Install the VA recommended switch and set to alarm at 2/3 of the tank height. There are valves that can isolate this alarm. These valves must be made lockable only in the operating position. B. Furnish report within one week of each facility inspection in Microsoft Word format by email to the COR and to the VA Headquarters office designated. Provide hard copies of data sheets and flue gas analyzer strip printouts to the COR within one week of visit. C. All safety-related deficiencies shall be immediately reported to the COR, Boiler Plant Supervisor and/or Chief Engineer during the inspection visit. Reference: VHA Boiler Plant Safety Devices Testing Manual, Fifth Edition APPENDIX B. ADDITIONAL SAFETY DEVICE TEST PROCEDURES FOR HOT WATER BOILERS Appendix B.1 INTRODUCTION Appendix B presents step by step test procedures for safety devices that are specific to hot water boilers. The appendix provides forms for obtaining and recording all necessary data for each safety device being tested. This Appendix is a supplement to Appendix A to be used in testing a hot water boiler. The basic information required in section A.3.3 and certification required in section A.3.4 must be included in the report of safety testing for a hot water boiler in order for the report to be VA compliant. The assumptions for the test procedures given in this Appendix are first listed. This information is then followed by one sheet for each device being tested to be used by the testing agency personnel as a check list and data form. These procedures must be made site specific to be in compliance with VA requirements. It is very important that all data required in these procedures are taken each time a test is made. Forms that contain pre-filled data lead to mistakes. Also, it is important not to use a check list form because a reviewer cannot verify that the test has been done correctly due to absence of data. Appendix B.2. ASSUMPTIONS FOR TEST PROCEDURE The test procedures in Appendix B makes certain assumptions that are listed below. PLEASE NOTE THAT THESE ITEMS ARE NOT ALWAYS REPEATED IN EACH TEST PROCEDURE BUT APPLY TO ALL TESTS. After each test, equipment should be returned to normal operating condition and the boiler should be fired to confirm its operability. Jumping means disabling the switch electrically. Any electric jumper application requires that all power to the device being jumped be shut off and only personnel that are trained and qualified to the correct level by NFPA 70E perform such tests. Pressure gages used in a test must be calibrated within prior 6 months. The set point is the value at which the safety device indicator is set. The trip point is the actual value at which the safety device activates. Some language used in the test procedures assumes that the set point equals the trip point.
