Z--GOGA 336173 - Repair Conzelman Road

Solicitation 140P2026R0106 is a HubZone small business set-aside construction project issued by the National Park Service Denver Service Center for the repair of Conzelman Road at the Golden Gate National Recreation Area in Marin County, California. The project focuses on stabilizing a roadway prism undermined by coastal bluff erosion through the construction of a concrete retaining wall featuring deep pile foundations, the installation of a steel bridge rail, and the adjustment of existing steel guardrails. The estimated value of the project is between $1,000,000 and $5,000,000, with a performance period of 180 days. The government will award the firm-fixed-price contract using the Best Value Continuum Tradeoff Process, where non-price factors are significantly more important than price. Evaluation factors include the construction schedule, project experience, key personnel experience, and past performance, listed in descending order of importance. Proposals must be submitted electronically by October 29, 2026, in two separate volumes covering technical qualifications and business/price data. Key requirements include compliance with the Davis-Bacon Act for prevailing wages, the provision of performance and payment bonds, and adherence to California ST-75 bridge rail and MASH guardrail standards.
