All bidders and subcontractors must hold current Oregon Construction Contractors Board licenses and comply with prevailing wage requirements under the Davis-Bacon Act and Oregon Revised Statutes 279C.840. Bidders must prequalify with the City of Ashland or Oregon Department of Transportation prior to bid submission. Bids must be submitted as lump-sum proposals with bid security equal to 10 percent of the maximum bid price. Successful bidders must furnish performance and payment bonds and maintain workers' compensation insurance. Required bid documents include a bid bond, affidavit of noncollusion, First-Tier Subcontractor Disclosure Form, and eight CWSRF compliance forms addressing prevailing wage agreements, DBE outreach, independent price determination, good faith efforts, lobbying certifications, and noncollusion sworn statements. Bidding documents are available for download at no charge from the OregonBuys procurement website. The bid remains subject to acceptance for 60 days after opening.
