Request for Proposal for General Contractor

The City of Manzanita, located in Oregon, is seeking a qualified General Contractor through a Request for Proposal (RFP) for the Manzanita Classic Street Connection project, a comprehensive infrastructure improvement initiative. The project encompasses approximately 1,600 linear feet of roadway reconstruction along Classic Street, involving water main installation, storm sewer system improvements, retaining wall construction, pedestrian pathway development, and traffic calming measures. Key deliverables include installing 10-inch HDPE water mains, 12-inch corrugated HDPE storm pipes, new curb and gutter systems, and comprehensive landscape restoration using native coastal range seed mixtures. Bidders must be registered with the Construction Contractors Board and provide a bid security of at least 10% of the bid amount. The evaluation process will utilize a 100-point scoring system, with 70 points for bid amount, 15 points for relevant experience, 5 points for proposed personnel and project organization, and 10 points for approach and schedule. A mandatory pre-proposal meeting and site tour is scheduled for April 29, 2025, at 11:00 am, with proposals due by May 20, 2025, at 2:00 PM. The anticipated contract start date is June 23, 2025, with substantial completion expected by November 21, 2025, and final completion by December 5, 2025.

The project is primarily funded through a State of Oregon grant to support infrastructure for affordable housing development, with a focus on complex construction conditions including steep slopes and unique sandy soil characteristics. While no specific set-aside designations for disadvantaged enterprises are explicitly mentioned, the project will require compliance with Oregon Bureau of Labor and Industries (BOLI) prevailing wage rates. Bidders must navigate challenging geological conditions, including potential seismic risks and loose eolian sand formations, as detailed in the geotechnical reports. The project involves specialized construction techniques and careful management, with potential material price escalation capped at 5% of the original contract price for specific materials like watermain pipeline, asphalt, guardrail, and retaining wall components. Though a specific total contract value is not definitively stated, the comprehensive nature of the infrastructure improvements, including utility installations, roadway reconstruction, and extensive engineering work, suggests a significant project budget. Contractors will need to demonstrate expertise in managing complex urban infrastructure projects with multiple technical and environmental considerations.
