RFP#2022-81 Engineering Services for the Tri-City WRRF Influent Pump Station Expansion Project

Clackamas County Water Environment Services (WES) issued Request for Proposals (RFP) #2022-81 for engineering services to support the Tri-City Water Resource Recovery Facility (WRRF) Influent Pump Station Expansion Project. The primary objective is to replace existing pumps and increase the facility's firm capacity from 50 MGD to 72.6 MGD to accommodate projected 2040 peak hour flows. Engineering services will encompass comprehensive project management, existing system evaluation, preliminary and final design, bid document preparation, and engineering support during construction. Evaluation criteria will focus on the project manager's qualifications, project team composition, firm experience, and overall project understanding and approach. The RFP was originally due on September 15, 2022, but was extended via Addendum 1 to September 21, 2022, at 2:00 PM Pacific Time, with an anticipated contract start date of October 2022. Design work is expected to continue through winter 2023, with construction to follow the design phase. Proposers must be prepared to enter Clackamas County's standard personal services contract, which includes specific insurance and rate requirements.

The capital budget for the project is estimated at $4,500,000, with no specific set-aside designations mentioned in the documentation. Multiple engineering firms submitted proposals, including Kennedy Jenks, Carollo, and Stantec Consulting Services, Inc. The Notice of Intent to Award indicates Carollo as the apparent successful proposer, scoring 88.25 out of 100 points in the evaluation process. The project involves expanding an existing influent pump station located in Clackamas County and Oregon City, which will require integration with current infrastructure documented in original plant record drawings from 1986. The expansion is part of a broader Willamette Facilities Plan that recommends infrastructure improvements to address growth, aging systems, and regulatory requirements through 2040. A 7-calendar day protest period was established following the Notice of Intent to Award, during which unsuccessful proposers may file formal protests to the contract award.
