This is an RFP Attachment D document for Washington County, Oregon, soliciting qualifications-based selection proposals for preliminary engineering, design, and related services for the Aloha Access Improvements Project. The project involves designing sidewalk infills on SW 187th Avenue, SW 182nd Avenue, and SW 174th Avenue, as well as an enhanced pedestrian crossing at SW 185th and SW Cascade Drive in the unincorporated Aloha community. The design work will be developed to a 30% level, following Metro criteria requiring a minimum 8-foot total width for sidewalks and buffers. Proposers must submit two substantially completed project samples from the past 10 years comparable to the requested services, with a maximum of 2 pages per project and two references for each project sample. The RFP was released on November 14, 2025, with questions due by November 28, 2025, and proposals required by December 5, 2025, at 5:00 PM PST. The estimated project construction cost is $3,292,485, with a scheduled bid-let date in March 2028 and estimated A&E services completion by December 2028.

The architectural and engineering services contract is valued between $700,000 and $1,400,000. The project includes a Disadvantaged Business Enterprise (DBE) participation goal, and proposers must demonstrate the ability to self-perform at least 51% of the contract value. Funding will be provided through the Regional Flexible Fund Allocation from Metro with local matching funds from the Major Streets Transportation Improvement Program (MSTIP) Opportunity Fund. The contract will be federally funded through the Oregon Department of Transportation (ODOT). Washington County reserves the right to negotiate scope, costs, and contract provisions with the selected proposer and anticipates awarding a single contract, with the final decision on which sidewalk infill segments to deliver based on the consultant's recommendations and available funding.
