Hi David, In accordance with the terms of the Construction Contract, FKAA respectfully requests the issuance of a Bulletin describing a proposed design revision so that the Contractor may prepare a formal Change Proposal for evaluation. These changes are described in the following enclosed documents: • Revised FKAA Sheet D3: Modify material transition from coupled connection to flanged connection. • New FKAA Sheet D6:Add new stainless-steel—to—PVC flanged transition detail, including restrained spool configuration. • Revised FKAA Section 33_05_31.16:Add requirements for restrained flange coupling adapters. • Revised FKAA Section 40 05 23.01: o Provide specification for field welding. o Add insulating gasket kit requirements. o Add field-applied petrolatum wax tape coating requirements for flanged assemblies. The intent of this revision is to modify the connection detail at the transition between stainless steel pipe and PVC. The approved plans currently indicate coupled transitions; however, based on field coordination and review of the Contractor's approved submittal, a flanged transition with a restrained spool piece is recommended in lieu of the coupled configuration to maintain constructability and consistency across the remaining conflict locations. Please advise if any additional technical information or supporting sketches are required to support preparation of the Bulletin. Thanks, Justin C. Dacey, P.E.

Protect stainless steel piping and fittings from carbon steel projections (when grinding carbon steel assemblies in proximity) and carbon steel contamination (do not contact stainless steel with carbon steel wire brush or other carbon steel tool). 3.05 FIELD WELDING A. Perform all field welding in accordance with AWS D1.6 and ASME Section IX. B. Field welding shall be performed only by welders certified for the applicable processes, materials, and positions. C. Protect adjacent materials and equipment from heat, sparks, and spatter; prevent contamination of stainless steel surfaces by carbon steel tools, grinding dust, or debris. D. Verify joint fit-up, alignment, bevel geometry, and root opening prior to welding. Do not weld over dirt, moisture, oil, or damaged surfaces. E. Joint Preparation: 1. Bevel pipe ends to the angles, typically 37.5 degrees, with a uniform land and root opening suitable for achieving full penetration. 2. Clean all weld surfaces to bright metal using non-ferrous tools. Remove oxides, coatings, cutting oils, and any foreign matter. 3. Ensure pipe alignment does not exceed tolerances of ASME B31.1/B31.3 as applicable. 4. Support piping to prevent movement, sagging, or distortion during welding. F. Purge Requirements: 1. Back purging with high-purity argon gas is required for all root passes. 2. Install temporary purge dams, purge bladders, or other approved purge devices to maintain purge gas enclosure throughout the root pass.

Reduce oxygen concentration on the weld backside to <_ 50 ppm prior to initiating the root pass. 4. Maintain purge flow until at least one hot pass has been completed and the root is fully protected against oxidation. 5. Protect purge equipment from moisture and displacement during welding. G. Welding Procedures 1. Perform root passes using the gas tungsten arc welding (GTAW/TIG) process unless otherwise approved. 2. Ensure full-penetration fusion through the entire pipe wall thickness. 3. Perform hot pass and fill passes using GTAW or GMAW. 4. Maintain interpass temperature within the limits specified in the WPS; do not exceed 350°F unless otherwise approved. 5. Provide wind shielding or temporary welding enclosures when welding outdoors to prevent disruption of gas shielding. 6. Grind intermediate passes as necessary to remove slag inclusions, porosity, or irregularities. 7. Form the final cap pass with a uniform, slightly convex contour, free of undercut, overlap, or excessive reinforcement. H. Environmental Controls: 1. Do not weld in rain, standing water, or high-moisture environments unless suitable protection is provided. 2. Shield weld zone from wind using screens, tents, enclosures, or other approved means. 3. Maintain a dry, clean surface free from condensation before and during welding. 4. Provide adequate ventilation for welding operations performed in confined spaces. I. Post-Weld Treatment: 1. Remove weld discoloration, heat tint, and oxides using mechanical cleaning and pickling paste suitable for stainless steel. 2. Perform passivation using citric or nitric solutions according to ASTM A380/A967. 3. Thoroughly rinse and neutralize treated areas after cleaning and passivation. 4. Do not use carbon steel brushes, grinding wheels, or tools at any point. J. Examination and Testing: 1. Perform visual inspection of all welds in accordance with AWS D1.6. 2. Repair defects in accordance with applicable codes. 3. Re-inspect repaired areas at no additional cost to the Owner. K. Cleaning and Restoration: 1. Remove welding tents, purge equipment, debris, temporary supports, and all foreign materials from the work site upon completion. 2. Restore piping coatings, insulation, jacketing, or protective coverings disturbed during welding operations. 3. Protect completed welds from contamination, mechanical damage, or exposure to carbon steel debris.

Apply corrosion-protection primer, profiling mastic (as required), and tape wrap to the following areas: 1. All exposed portions of flanges, including bolt heads, nuts, washers, and flange rims. 2. All field-welded joints, extending a minimum of 6 inches beyond each weld heat-affected zone. B. Wrap Installation: 1. Apply petrolatum primer paste to all surfaces to be wrapped, in accordance with the manufacturer's instructions. 2. Apply profiling mastic as required to fill voids, transitions, and irregular geometries and to create a uniform profile suitable for proper tape adhesion. 3. Wrap with petrolatum tape using a minimum 55 percent overlap, or greater where recommended by the manufacturer. 4. Extend the tape wrap a minimum of 6 inches beyond the weld heat-affected zone, and fully encapsulate all bolts, nuts, washers, and flange perimeters. C. Bedding and Backfill: 1. Provide uniform bedding beneath flanges and welded areas; do not leave voids or point loads beneath hubs or fittings. 2. Protect wrapped assemblies from sharp objects and prevent displacement of the wrap during placement of bedding and backfill. 3. Place backfill only after the Engineer has verified that the wrap installation is complete, continuous, and free of visible defects.
