The Tri-City Water Resource Recovery Facility (“WRRF”) Influent Pump Station (“IPS”) Expansion Project will increase the facility’s firm pumping capacity from 47.6 MGD to 72.3 MGD and replace five influent pumps, associated electrical gear, controls, and suction/discharge piping. The work will occur entirely within the existing, continuously operating WRRF. The project requires careful sequencing, electrical and controls cutovers, and management of temporary bypass pumping to maintain service throughout construction. Clackamas Water Environment Services (“WES”) will use the Construction Manager / General Contractor (“CM/GC”) delivery method to integrate design and construction planning, improve risk management, and maintain operational continuity during construction. The CM/GC will first perform preconstruction services, then, upon agreement of a Guaranteed Maximum Price (“GMP”), may proceed to construction under a contract amendment.
