J045--FY27 Boilers Maintenance & Testing

The due date for Quote Submittal is changed from November 6, 2026, to November 10, 2026 at 10 AM AST. All other sections of the solicitation remain unchanged. RESPONSES TO QUESTIONS RECEIVED: Q1. Semiannual Safety-Device Testing: VHA Directive 1810, Appendix A, Section 2(a), establishes that safety devices requiring semiannual testing are ordinarily tested once annually by VA medical facility personnel and once annually by a qualified testing contractor, unless an alternative arrangement is approved. Does the Government require the contractor to perform both semiannual testing events under this solicitation? If so, has the alternative testing arrangement received the required approval? VACHS Boiler Plant personnel will perform the required semiannual safety-device testing. The Contractor shall perform the safety-device testing required under the PWS during its scheduled annual inspection and testing services. Q2. Monthly Safety Device Testing: PWS Section V(Q) includes safety-device tests for which the VHA Boiler and Associated Plant Safety Device Testing Manual establishes monthly testing frequencies, including primary and auxiliary low-water cutoffs, high- and low-water alarms, and the main flame-scanner flame-out test. Does the Government require the contractor to perform these tests monthly throughout the contract period, or will VACHS personnel continue performing the monthly tests while the contractor performs the scheduled maintenance and safety-device testing services? VACHS Boiler Plant personnel will perform the required monthly safety-device testing. Q3. Frequency of Nondestructive Testing, Component Replacement and Engineering Evaluations: PWS Sections V(I), V(L), V(U), V(V), and V(W) establish requirements involving component replacement, nondestructive testing (NDT), pressure-vessel inspections, and engineering evaluations, including ultrasonic thickness measurements, magnetic-particle examinations, and assessments of maximum allowable working pressure (MAWP) and remaining useful life. However, VHA Directive 1810, Appendix B, Table 2, establishes different inspection frequencies depending on the activity. For example, annual boiler inspections are required, whereas internal deaerator weld examinations using wet magnetic-particle testing are required at six-year intervals. Clarify the following: a. Nondestructive Testing: Are ultrasonic thickness measurements and magnetic-particle examinations required annually for each boiler and the deaerator, or are these examinations required only when indicated by inspection findings, equipment conditions, or established inspection intervals? The scope of this requirement applies to the Boilers only. b. Deaerator Weld Examination: Is the six-year internal deaerator weld examination required during the base contract period or any of the option years? If so, please identify the date of the most recent examination and the next scheduled examination. Not applicable. This service is cover under another service contract c. Engineering Evaluations: Are MAWP calculations, remaining-useful-life assessments, and deterioration-rate evaluations required annually for each boiler, deaerator, and condensate return tank, or only when inspection findings or equipment conditions warrant such evaluations? Not applicable. This service is not covered under this requirement. d. Component Replacement: Are component replacements identified in the PWS mandatory during each annual maintenance period, regardless of condition, or are replacements required only when inspection or testing establishes a deficiency, except where the PWS expressly requires replacement? Mandatory parts to be replaced annually during annual maintenance, regardless of its conditions: Sight glass with new seals, Compress air belt, oil filters, air filter, water gasket seal kits and fire side gaskets seal kit. e. Firetube Inspection Methods and Waterside Deterioration: PWS Section V(U) references fiberoptic inspection of boiler tubes, while Section V(V) establishes ultrasonic thickness measurement requirements. In a firetube boiler, fiberoptic examination from inside a tube primarily evaluates its fireside surface and does not directly establish the condition of the exterior waterside surface, where corrosion and pitting may occur. Please clarify whether the Government requires fiberoptic visual examination, ultrasonic thickness measurements, or additional examination methods capable of evaluating tube-wall deterioration affecting either surface. The Government requires the inspection methods specified in the Performance Work Statement (PWS). Fiberoptic inspection and ultrasonic thickness testing are complementary requirements, and both shall be performed. f. Boiler Tube Quantities and Technical Documentation: For each boiler, please identify the total number of firetubes, nominal tube diameter, original wall thickness or gauge, and applicable tube specifications. Please provide, if available, manufacturer drawings, tube-layout diagrams, pressure-vessel drawings, or other technical documentation identifying the shell, tube arrangements, tube sheets, and applicable pressure-retaining components, so that offerors can quantify the inspection scope. The Government has provided all available identifying information and that quotes/offers should be based on the PWS requirements and field verification. g. Extent of Tube Examination and Sampling Requirements: Does the Government require examination and wall-thickness measurements of every firetube in each boiler, or is an engineer-justified representative sampling program acceptable? If sampling is permitted, please identify any minimum sample quantity or percentage, prescribed examination locations, acceptance criteria, and requirements for expanding the examination when initial results reveal pitting, corrosion, thinning, or other deterioration. May the qualified inspecting engineer establish and justify the sampling methodology based on equipment condition, applicable standards, and inspection findings? The Government does not require examination or ultrasonic thickness measurements of every firetube. The Performance Work Statement requires inspection of a representative number of tubes and ultrasonic thickness testing of representative samples, with additional testing of areas exhibiting indications of corrosion, erosion, or other deterioration. The Contractor's Qualified Professional Inspector may establish and justify the sampling methodology using professional engineering judgment and applicable industry standards, provided the inspection is sufficient to assess equipment condition and support all required findings, calculations, and recommendations. h. Boiler shell examination and engineering certification: Please identify the required extent of ultrasonic thickness measurements and other nondestructive examinations of boiler shells, tube sheets, and other applicable pressure-retaining components. For the MAWP, deterioration-rate, and remaining-useful-life evaluations required by the PWS, does the Government require a formal report signed and sealed by a licensed Professional Engineer? Please identify any specified inspection coverage, minimum-thickness criteria, engineering standards, or historical thickness data to be used. Must the engineering determinations address the complete boiler pressure vessel, including firetubes and shell, or only components examined under the prescribed inspection program? The Government requires ultrasonic thickness testing of representative samples and all areas exhibiting signs of corrosion, erosion, or other deterioration. PWS does not prescribe specific inspection coverage percentages, minimum thickness criteria, historical thickness data, or a requirement for a signed and sealed Professional Engineer report. The Contractor shall use applicable ASME Code requirements, inspection findings, and professional judgment to perform the required MAWP, deterioration-rate, and remaining-life evaluations and document the results in the final report. Q4. The PWS incorporates maintenance, inspection, and testing requirements applicable to the deaerator (DA) and condensate return tank (CRT), as established by VHA Directive 1810 and the VHA Boiler and Associated Plant Safety Device Testing Manual. However, the solicitation provides pricing contract line items (CLINs) only for the three steam boilers and does not identify the DA and CRT equipment specifications. To establish the equipment covered by the contract and prepare an accurate firm-fixed-price quotation, please clarify the following: a. Identify the manufacturer, model, serial number, and quantity of each DA and CRT included within the contractual scope of work. b. Provide the vessel capacity, design pressure, normal operating pressure, and applicable ASME identification or nameplate information for each DA and CRT. c. Provide, if available, the applicable manufacturer maintenance instructions, equipment data sheets, and relevant drawings identifying the installed DA and CRT configurations. d. Should offerors allocate the costs associated with DA and CRT maintenance, inspection, and testing among the three existing boiler CLINs, or will the Government establish separate CLINs for these services? Not applicable. This service is not covered under this requirement. Q5. PWS Section V(I) requires the contractor to replace, calibrate, and test boiler steam safety valves, with calibration and/or testing performed onsite. The VHA Boiler and Associated Plant Safety Device Testing Manual also establishes testing requirements applicable to boiler, deaerator, and pressure-reducing valve (PRV) downstream safety valves. To determine the complete scope of testing, calibration, and replacement services and prepare an accurate firm-fixed-price quotation, please clarify the following: a. Identify the total number of steam safety valves included within the contractual scope of work, specifying their installed locations, including those associated with each steam boiler, the deaerator tank, and downstream of the steam pressure-reducing valve (PRV). Review the VHA Boiler and Associated Plant Safety Device Testing Manual for guidelines and for typical safety devices equipment in a Boiler. b. For each safety valve, provide the manufacturer, model, nominal inlet and outlet sizes, serial number or other identification, and applicable ASME/National Board certification information. Review the VHA Boiler and Associated Plant Safety Device Testing Manual for guidelines and for typical safety devices equipment in a Boiler. c. Identify the set pressure (psig), rated steam discharge capacity (lb/hr), and applicable pressure and temperature ratings for each valve. The Government does not have verified safety valve set pressures, steam discharge capacities, or pressure/temperature ratings available for distribution under this solicitation. Offerors shall base their quotes/offers on the requirements of PWS and the identified boiler equipment. Verification of valve nameplate data and equipment ratings shall be performed during the inspection and testing activities required under the contract. d. Please confirm whether each of the three steam boilers is equipped with two safety valves, reportedly set at 130 psig and 135 psig, respectively, and whether the deaerator system includes one safety valve installed on the tank and another downstream of the PRV. Please identify any additional safety valves included within the contractual scope. Each of the three boilers is equipped with two steam safety valves with nominal set pressures of 130 psig and 135 psig, respectively. The contractual scope includes the inspection, testing, calibration, and evaluation of these boiler safety valves and associated boiler safety devices identified in the PWS. The deaerator system and its associated safety valves are not included within the scope of this contract. Offerors shall base their quotations on the solicitation requirements. Verification of installed equipment, valve nameplate data, and operating condition shall be performed during contract execution.

e. Does PWS Section V(I) require replacement of all existing boiler steam safety valves during each annual maintenance period, regardless of their condition, or is replacement required only when a valve fails inspection or testing? Please also clarify whether any replacement requirement applies to the deaerator and PRV downstream safety valves. The Government's intent is to inspect, test, and calibrate the boiler steam safety valves. Replacement is required only when a safety valve cannot be successfully calibrated, fails testing, or is otherwise determined to be defective or unserviceable. This requirement applies to the boiler steam safety valves within the scope of the PWS. f. Please identify whether the Government requires onsite testing and certification of all applicable safety valves, including the boiler, deaerator, and PRV downstream valves, and whether any valves must be removed for shop testing, repair, or recertification. The Government requires testing and calibration of the boiler safety valves in accordance with the PWS. Valve removal, shop testing, repair, recertification, or replacement shall only be required when a valve cannot be successfully tested, calibrated, or is otherwise determined to be defective or unserviceable. The PWS does not specifically require testing, certification, removal, repair, or replacement of deaerator or downstream PRV safety valves. g. Please provide an equipment schedule or existing valve inventory, if available, identifying the specifications and locations of all safety valves included within the contract. The Government does not have an equipment schedule or valve inventory available for distribution under this solicitation. The boiler scope includes six (6) steam safety valves total, consisting of two (2) safety valves per boiler with nominal set pressures of 130 psig and 135 psig. Offerors shall base their quotations on the solicitation requirements. Verification of valve specifications, nameplate data, and exact locations shall be performed during contract execution. Q6. The solicitation identifies the manufacturers and serial numbers of the three steam boilers; however, the Performance Work Statement does not identify whether the boilers and their associated systems remain in their original equipment manufacturer (OEM) configurations or have undergone subsequent alterations, modifications, equipment replacements, or retrofits. Clarify the following: a. Whether any of the three boilers have undergone modifications or alterations from their original OEM configurations, including replacement or retrofitting of the original burner assemblies. b. For each boiler with modifications or retrofits, identify the manufacturer, model, and configuration of the replacement equipment and describe the extent of the alterations necessary to integrate that equipment into the existing boiler system. c. Identify all additional, replacement, or modified components associated with such alterations, including, but not limited to, fuel pumps, fuel-pressure regulating or throttling valves, fuel-train components, piping arrangements, combustion controls, burner management systems, safety interlocks, instrumentation, electrical controls, and associated auxiliary equipment. d. Identify any additional equipment or components installed as part of these modifications that are included within the maintenance, inspection, calibration, testing, or repair requirements of the current PWS. e. Where the installed equipment differs from the original OEM configuration, identify the applicable manufacturer maintenance and testing requirements and provide, if available, current as-built drawings, equipment schedules, control diagrams, operating sequences, and documentation of the modifications. The Government does not have modification records, as-built drawings, equipment schedules, control diagrams, or other documentation available for distribution under this solicitation. Offerors shall base their quotations on the equipment identified in the PWS and the requirements specified therein. Any existing field modifications, retrofits, equipment replacements, or deviations from the original OEM configuration shall be identified and documented by the Contractor as part of the inspection, testing, and evaluation activities required under the contract Q7.PWS Section V(B) requires inspections, testing, and calibrations to comply with the written recommendations of the equipment manufacturers, the VHA Boiler and Associated Plant Safety Device Testing Manual, and applicable NFPA 85 requirements. The Superior Boiler manufacturer s maintenance instructions prescribe certain daily, weekly, and monthly operational and functional checks, as well as semiannual fireside cleaning and associated maintenance activities. However, VHA Directive 1810, Appendix B, Table 3B, establishes an annual fireside-cleaning frequency for high-pressure steam boilers. The Directive also distinguishes routine boiler-plant operational duties from inspections and testing that must be performed by qualified contractors. Please clarify the following: a. Are the daily, weekly, and monthly manufacturer-recommended operational and functional checks required to be performed by the contractor at the specified frequencies, or will these activities remain the responsibility of VACHS boiler-plant personnel? Daily, weekly, and monthly operational and functional checks identified in the manufacturer's operating and maintenance manuals are considered routine boiler plant operational activities and shall remain the responsibility of VACHS boiler plant personnel. The Contractor is not required to perform recurring daily, weekly, or monthly operational checks at the frequencies specified by the manufacturer unless such services are specifically included in the approved maintenance schedule developed under this contract. b. Does the Superior Boiler manufacturer s semiannual fireside-cleaning recommendation require the contractor to perform two complete fireside-cleaning services annually, rather than the single annual fireside-cleaning service established by VHA Directive 1810, Appendix B, Table 3B, or is one annual fireside-cleaning service sufficient to satisfy the contractual requirements? Contractor shall perform one comprehensive fireside cleaning and inspection annually in accordance with the PWS requirements and applicable VHA guidance. If, during the course of inspection or operation, conditions are identified that warrant additional cleaning, the Contractor shall document the condition and provide recommendations to the COR for review and consideration. c. Are other manufacturer-recommended maintenance activities exceeding the frequencies established by VHA Directive 1810 required to be performed by the contractor, or will the contractor s responsibilities be limited to the maintenance, inspections, calibrations, and safety-device testing specifically scheduled under the PWS? The Contractor shall comply with the maintenance, inspection, calibration, testing, evaluation, and reporting requirements specifically identified in the PWS. Manufacturer recommendations should be utilized as part of the Contractor's technical evaluation and execution of the required services. However, the…
