RFP 20262033 Goodpasture Island Road Bridge Seismic Retrofits

The City of Eugene is soliciting engineering services for seismic retrofit work on the Goodpasture Island Road Bridge (Bridge #09359) over Delta Highway through RFP 20262033, with proposals due by March 25, 2026 at 2:30 p.m. and a Notice of Intent to Award anticipated by April 15, 2026. The 15-month project, federally funded with FHWA participation coordinated through ODOT, requires comprehensive engineering design and permitting support for Phase I and Phase II seismic strengthening retrofits of this 228-foot-long, four-span prestressed concrete bridge originally constructed in 1964. Deliverables include environmental services (hazardous materials assessment, permitting, wetland delineation), utility coordination, survey work, structural analysis and design calculations, traffic management planning, and bid support, culminating in a final Plans, Specifications, and Estimate (PS&E) package due by June 25, 2027. The selected consultant must demonstrate strong project understanding and approach (15 points), provide detailed discussion of key project elements, opportunities, and constraints (30 points), and possess professional liability insurance of at least $2,000,000, commercial general liability of $2,000,000 per occurrence with a $4,000,000 annual aggregate, and workers' compensation insurance. The proposed retrofit strategy addresses seismic deficiencies including installation of reinforced concrete shear lugs, beam seat extensions, isolation of the superstructure, replacement of bearing pads, and strengthening of critical concrete elements, with estimated construction costs ranging from $1.43 million to $1.91 million. All work must comply with ODOT Bridge Design Manual, AASHTO standards, AASHTO LRFD Bridge Design Specifications, ODOT Geotechnical Design Manual, FHWA Seismic Retrofitting Manual, applicable federal regulations, Title VI non-discrimination provisions, Oregon employment practices regulations, and NEPA requirements.

A Disadvantaged Business Enterprise (DBE) goal may be assigned to this contract, with the overall ODOT goal for FHWA-funded contracts established at 11.6%, though the specific DBE goal percentage for this project has not been identified in preliminary RFP documentation. The contract compensation methodology is Cost Plus Fixed Fee (CPFF) with a Not-to-Exceed (NTE) amount to be negotiated on a monthly invoicing basis for actual costs incurred, with the final NTE amount to be determined during contractor selection negotiations. No incumbent vendors or existing contractors are identified for this project, though the procurement builds upon prior seismic vulnerability assessments conducted by OBEC Consulting Engineers in 2016 and geotechnical investigations documented in reports prepared by Foundation Engineering, Inc. and DOWL, LLC. The bridge is heavily trafficked with 2010 Average Daily Traffic (ADT) of 16,368 vehicles on Goodpasture Island Road and 41,091 vehicles on Delta Highway, requiring staged construction to minimize traffic impacts. Professional services are estimated at 15 percent of construction bid items, with construction engineering services estimated at 20 percent and contingencies for temporary traffic control and mobilization each estimated at 10 percent of bridge construction costs, though the total project budget range reflects the AACE Class 3 estimate accuracy of -10% to +20%.
