Ullrich WTP Inherently Safer Disinfection Conversion

The City of Austin is seeking to convert the disinfection process at the Albert H. Ullrich Water Treatment Plant from chlorine and ammonia gas to an On-Site Generated Sodium Hypochlorite and Liquid Ammonium Sulfate system to improve operational safety and reduce risks associated with hazardous gas storage and handling. The solicitation, identified as CSP 6100 CLMB344, was posted on April 27, 2026, with proposals due by July 23, 2026, and is targeted under NAICS code 237310 for water and wastewater treatment construction. The project requires the decommissioning of existing gas feed systems and the installation of new chemical generation and feed infrastructure, including all associated piping, controls, instrumentation, and integration into the plant’s existing treatment processes. Work must comply with ASTM, ANSI, NFPA, OSHA, and TCEQ standards, with all materials delivered in original manufacturer packaging, properly labeled, and stored within specified temperature ranges. Performance Acceptance Testing spans from April 2026 through July 2027, with final acceptance contingent upon successful Site Acceptance Tests and submission of certified documentation. The contractor is responsible for all aspects of installation, testing, and commissioning, and must furnish performance and payment bonds equal to 100% of the contract sum, along with a warranty bond for the sodium hypochlorite system. Subcontractor participation must include documented Good Faith Efforts to engage Minority and Women-Owned Business Enterprises, though no federal socioeconomic program certifications like DBE or HUBZone are required. All testing and inspections must adhere to ASTM E329 and ISO/IEC 17025 standards, with documentation submitted to the Engineer for approval. Piping and equipment must be labeled per ASME A13.1, with die-cut vinyl labels and stainless steel nameplates meeting specified dimensions and durability requirements. Proposals must be submitted electronically via the Austin Finance Online eResponse portal by 2:00 PM Austin time on the deadline, categorized into Offer and Certifications, Price Offer, Technical Offer, and Compliance Plan volumes, with no page limits specified. While the contract value remains unlisted due to incomplete pricing data, the project involves substantial infrastructure replacement and is governed by construction-specific specifications rather than standard FAR clauses, with no formal COR, COTR, or PCO identified. Payment details, invoicing systems, and accounting codes are not specified, and
