H335--Boiler Useful End of Life Study

SCOPE OF WORK: The contractor shall provide all labor, materials and equipment necessary to inspect, test and conduct the study of useful life expectancy of all 5 boilers and associated ancillary equipment located the Lyons Campus VA Medical Center. All the information for the boilers and other equipment are to be addressed are described in Attachment 1 Equipment List. The work shall be documented in a full report of findings and recommendations. The report must be stamped by a licensed professional engineer. C. SPECIFICATIONS: 1. Qualification Requirements for Contractor and Inspection Personnel: A. A professional engineering firm (Professional License (PE)) that specializes in life expectancy evaluations. Shall be part of the team and provide an analysis and recommendations under their seal based on the evaluation of the boiler and associated equipment by means of visual inspection and non-destructive testing conducted by experienced boiler inspectors and non-destructive testing experts on the team. B. The inspections shall be supervised on-site by a Qualified Professional Inspector , defined as anyone or combination of the following. Proof of qualifications shall be provided with the bid and as part of the final report. 1) A boiler inspector who has a valid commission from the National Board of Boiler and Pressure Vessel Inspectors. 2) A boiler inspector who has qualified by passing a written examination under the laws, rules and regulations of a jurisdiction of a state. 3) A boiler inspector who is regularly employed as a boiler inspector by a jurisdiction that has adopted and administers one or more sections of the ASME Boiler and Pressure Vessel Code as a legal requirement, and has a representative serving as a member of the ASME (American Society of Mechanical Engineers) Conference Committee. 4) A boiler inspector who is regularly employed by an insurance company that has been licensed or registered by the appropriate authority of a state of the United States to write boiler and pressure vessel insurance. C. Non-destructive testing personnel shall be certified to American Society for Non-destructive Testing (ASNT) Level II, who are experienced in evaluating boilers and associated equipment. 2. Inspector: A. The Qualified Professional Inspector shall demonstrate familiarity with and ready access to the current versions of the following codes and manuals: 1. ASME Boiler and Pressure Vessel Code 2. ASME B31.1, Power Piping Code 3. ANSI/NB-23, National Board Inspection Code 4. NACE International Standard RP0590, Recommended Practice for Prevention, Detection and Correction of Deaerator Cracking 5. VHA Boiler Plant Safety Device Testing Manual, current edition. B. The NDT technicians shall demonstrate familiarity with and ready access to the current version of: 1. NACE International Standard RP0590, Recommended Practice for Prevention, Detection, and Correction of Deaerator Cracking D. INSPECTION REQUIREMENTS FOR BOILERS 1. The contractor shall develop a detailed list of information required at least two weeks prior to the inspection to allow the VA to compile the information. 2. The contractor shall develop a detailed schedule of the inspection in consultation with the VA COR to ensure availability of equipment as needed during the execution of the project. 3. The contractor shall visually inspect the following items and document the locations with a sketch or pictures. Any adverse findings must be documented with pictures and notes in detail. All data shall be included in the final report as supporting documentation. A. Review the boiler/s history including operating conditions, date of last inspection, current inspection certificate, ASME stamping, National Board registration number, materials of construction, extent of post weld heat treatment, history of repairs and modifications. B. All welded and threaded pipe connections to the boiler shell or drum for signs of leakage or defects in the welded areas. Defects must be documented as to location with a sketch or picture and be non-destructively tested. C. Boiler support structure for proper alignment, evidence of sagging, shifting or misalignment. D. Boiler casings for signs of warping, misalignment and overheating. E. All furnace tubes and all accessible convection tubes for alignment, evidence of corrosion, erosion, bulges, sagging, defective or deteriorated welds. F. Exposed surfaces of steam and mud drum in furnace, particularly ligament areas between tubes, for evidence of corrosion, cracking, scale buildup, other defects. G. Refractory for cracking, shifting, sagging, bulging or general deterioration. H. Internal areas of steam drum and mud drum (inside boiler shell in fire tube boilers). 1. Welded outlet connections. 2. Surface of drums for pitting or surface discontinuities. 3. Ligament areas between tube holes for cracking. 4. Each tube end and internal surface of representative number of tubes for pitting, erosion, corrosion and excessive scale buildup. Utilize fiber optic inspection equipment to inspect interior of tubes. 5. Clean and inspect shell or tube sheet between tube holes for cracking.
