Description
The National Park Service is seeking information from interested contractors for the repair of Conzelman Road at Golden Gate National Recreation Area, Marin County, California. The project involves the construction of a concrete retaining wall along a one-way/single-lane segment of the road, which has been threatened by coastal erosion. The wall will have a steel bridge rail affixed to the top, and existing steel guardrail will be adjusted to align with the bridge rail. The project requires protective measures to ensure the surrounding area remains undisturbed, and daily work schedules will be required for work in archeologically sensitive areas. The Government anticipates issuing a competitive Request for Proposals (RFP) around Winter 2026/Early 2027 and awarding a single Firm-Fixed-Price (FFP) contract.
• The project is located at Golden Gate National Recreation Area, Marin County, California.
• The roadway can be fully closed during construction activities.
• The site requires protective measures to ensure the surrounding area remains undisturbed.
• Daily work schedule will be required for all work occurring within archeologically sensitive areas.
• The construction site is within 12 miles of the nearest suppliers and lodging facilities.
• The Park will remain open during construction, thus contract activities and logistics must be structured and scheduled to minimize visitor impact.
