Stewart II – City Manager Dan Mahlum, PE – Director 1 4/23/2026 12:22:20 PM J:\Data\PSC\21-0236\00 Contract\A-9\Amend No. 9_SOW_PWRF PH 2 SDC.docx Scope of Work Amendment No. 9 City of Pasco Process Water Reuse Facility Improvements Winter Storage April 2026 Background The City of Pasco (City) has requested that RH2 Engineering, Inc., (RH2) perform additional tasks beyond the original scope of work for services during construction. Additional on-site observation time was required to support project closeout and confirm that the system is functioning as intended. This effort has included multiple return visits to address evolving punch list items identified during final inspections, many of which required review of corrective actions, coordination with the contractor, and documentation for acceptance. Project completion is anticipated for June 1, 2026. Furthermore, installation of a reticulation line as part of Process Water Reuse Facility Pretreatment Improvements Phase 2: Winter Storage enabled the irrigation pump station (IPS) wet well to be drained, allowing RH2 to enter the structure and perform a detailed condition assessment to evaluate potential corrosion associated with sodium hypochlorite exposure and to develop appropriate replacement recommendations. Task 8 – Services During Construction (Regular) Objective: Provide additional construction-phase services to support project closeout and provide additional on-site observation of corrosion-related issues at the IPS for reliable system performance and long-term integrity. Approach: Provide additional on-site observation and construction-phase services from January 1, 2026, through June 1, 2026, to support project closeout, including addressing civil and mechanical punchlist items, reviewing corrective actions, coordinating with the contractor, and supporting system testing. CSNW will support this effort by performing these same tasks for electrical and control items. Provide additional condition assessment related to corrosion within the IPS well and prepare an amendment to the IPS Corrosion Investigation Technical Memorandum prepared by RH2. Provide the updated technical memorandum to the City for review and comment and finalize the amended technical memorandum.
