The Contractor will provide the Department of Water Resources (DWR), Division of Operations and Maintenance (O&M), Mechanical Engineering Branch, on an as-needed as-directed basis, metallurgical engineering expertise to perform material failure analysis, testing, and evaluation of mechanical components associated with State Water Project (SWP) facilities and DWR projects, as shown in Exhibit A, Attachment 1 – State Water Project Facilities. A. Primary Services 1. Perform material failure analyses on components of equipment such as pump impellers, wear rings and plates, diffusers, pump shafts, cases, and seals; and perform engineering analysis of material test results to provide recommendations for design and material changes. a. Provide extensive documentation of evaluated components including photographic documentation showing abnormalities (cavitation, metal wastage by impingement, corrosion, coating failures, weld decay, and cracking). b. Provide physical evaluation of failed components such as determination of pit depths, and metal loss. c. Perform forensic evaluation of abnormalities including dye penetrant testing, magnetic particle testing, and scanning electron microscopy (SEM) to determine the mechanism and mode of failure. 3. Provide technical reviews of welding procedures including identification of material to be welded, the use of weld pretreatments, selection of weld material, specified rates of welding, and post weld treatments needed to ensure adequacy of welds and to maintain the integrity and safe operation of equipment. Provide recommended changes to procedures to ensure they are adequate for the situation. 4. Review and evaluate corrosion-resistant materials and recommend equipment operational constraints to prevent catastrophic failure of equipment when defects and deficiencies in components are found. B. Ancillary Services The Contractor will provide the following services only to support items A.1 – A.4 above. 1. Attend meetings and site visits. 2. Ensure that DWR staff is proficient with any developed welding procedure and/or specifications that are developed. This may include training, question and answer session, or weld qualification testing.
