RFP # 2025-54 Conway Creek at Aschoff Road Culvert Replacement Project

Clackamas County is seeking engineering and design services for the Conway Creek at Aschoff Road Culvert Replacement Project through a Qualifications Based Selection (QBS) process. The project involves replacing two existing culverts (a 40-inch corrugated metal and a 36-inch concrete culvert) that currently convey Conway Creek under Aschoff Road in Rhododendron, Oregon. Key project objectives include improving fish passage for wild coho salmon, winter steelhead, cutthroat trout, and lamprey by creating a larger structure that meets Oregon Department of Fish and Wildlife requirements. The project is funded through Federal Highway Administration (FHWA) and County Road Fund sources, with proposals due by July 1, 2025, at 2:00 PM PST. Proposal evaluations will focus on project team qualifications, project understanding and approach, communication and availability, and supportive information. The anticipated contract timeline includes an award in August 2025, a contract start date of October 7, 2025, and a performance period extending to March 2028 for Phase I, with potential Phase II completion by December 2029.

The procurement includes a Disadvantaged Business Enterprise (DBE) participation goal of 15%, serving approximately 53 residents and expected to create an additional 0.76 miles of high-quality anadromous fish habitat. The engineering and design services contract is valued between $475,000 and $525,000, with an estimated total construction cost of $1,209,900. The project will require integration with existing road infrastructure and environmental considerations specific to the Conway Creek area. While no incumbent vendors are specifically mentioned, potential respondents must demonstrate expertise in culvert replacement, fish habitat restoration, and compliance with federal and state transportation and environmental regulations. Interested firms will need to provide comprehensive documentation of their qualifications, technical approach, and ability to meet the project's specific environmental and engineering requirements.
