The Oregon Department of Aviation issued an Invitation to Bid (ITB) for a Public Improvement and Public Works Contract to perform runway, taxilane, and apron surface seal work at Mulino State Airport located in Clackamas County. The project scope includes crack sealing, asphalt concrete patching, standard seal coat application, and pavement marking installation across Runway 14-32, multiple taxilanes (A1-A3), and associated apron areas, with work quantities encompassing 21,724 linear feet of crack sealing, 906 linear feet of AC patching, 54,666 square yards of surface seal, and 9,268 square feet of pavement markings. Bidders were required to submit proposals by April 1, 2026, at 4:00 PM Pacific Daylight Time through the OregonBuys electronic procurement system, with a voluntary pre-bid conference held on March 18, 2026, via Microsoft Teams to discuss material requirements, quality control procedures, safety protocols, and specialized airfield paving construction requirements. The contract requires substantial completion within 13 consecutive calendar days of the Notice to Proceed (anticipated summer 2026 start date) and final completion within 30 calendar days, with three distinct phases: Phase 1 covering crack repair and AC patching (7-11 days), Phase 2 addressing surface seal application (4 days), and Phase 3 covering pavement marking installation (3 days). Award will be made to the lowest responsive, responsible bidder on a lump-sum basis, with evaluation criteria requiring bidders to demonstrate compliance with prevailing wage requirements under both Oregon Bureau of Labor and Industries standards and the federal Davis-Bacon Act (with the higher rate applicable), registration with the Oregon Construction Contractors Board prior to bid submission, and ability to perform at least 25 percent of total contract work with the contractor's own organization.

All bidders must be registered with the Oregon Construction Contractors Board and comply with prevailing wage and Davis-Bacon Act requirements, with no specific set-asides for disadvantaged enterprises noted in the procurement documents. Bidders must submit a 10 percent bid security and, upon award, provide Performance and Payment Bonds each equal to 100 percent of the awarded contract amount, comprehensive insurance coverage including $1,000,000 Commercial General Liability and Commercial Automobile Liability per occurrence, and a $5,000,000 Excess/Umbrella Liability policy; additional insurance requirements include workers' compensation insurance in compliance with Oregon Revised Statutes 656.001 through 656.794 with combined single-limit coverage of not less than $1,000,000.
