Task 1.0 — Assumptions <br />• IRCDUS to provide a review of the technical memorandum prior to the draft <br />review meeting. <br />Task 2 - Capital Upgrades and Renewals Matrix <br />Consultant will attend (1) site visit at the WTP. The site visit will evaluate the necessary <br />improvements to maintain the existing rated capacity of the WTP. The site visit will <br />consist of a walkthrough of each component of the WTP including the following: <br />• Raw water system <br />• Cartridge filter vessels <br />• Process piping <br />• Post treatment system including blowers, scrubbers, recirculation pumps, <br />degasifiers, clearwell support structure and mixing bay <br />• Chemical systems including scale inhibitor, sulfuric acid, caustic, CO2, and <br />chlorine <br />• Electrical and Standby Emergency Power - Consultant will utilize the services of <br />subconsultant C&W Engineering to evaluate the necessary improvements of the <br />existing electrical system. <br />• General site maintenance items <br />• Building components including containment structures, air intake louvers, <br />exhaust fans, doors, coating systems, etc. <br />Consultant will create a matrix to prioritize the improvements identified in the WTP site <br />visit. The matrix deliverable will be provided in a tabulated format and be utilized to <br />calculate and assign a priority level to each individual item. Prioritization will be based <br />on the primary objectives that include, but are not limited to improvements for regulatory <br />compliance, reliability, efficiency and resilience. The matrix table will include the <br />following criteria: <br />• Criticality to treatment/water quality <br />• Criticality to high service pumping <br />• Impacts to treatment <br />• Impacts to operation <br />• Impacts to maintenance <br />• Intangibles such as permitting, operating cost impacts, resiliency, efficiency, <br />reliability, etc. <br />• Capital costs. Consultant will prepare a Class 5 Opinion of Probable Construction <br />Costs (OPCC) for the proposed improvements. <br />Task 2.0 — Deliverables <br />• Matrix and recommendations to be provided in the technical memorandum. <br />Task 2.0 — Assumptions <br />• IRCDUS to provide all requested historical data and provide access to the WTP. <br />K\WPB_Civil\General\King\Marketing\IRCDUS\Oslo WTP Maintenance Projects\2025.0107 Oslo WTP Maintenance Projects - <br />Scope.docx <br />
