Quick Summary
The Department of the Interior, National Park Service (NPS), through its DSC Contracting Services Division, is conducting market research via a Sources Sought Notice for the repair of Conzelman Road (GOGA 336173) at the Golden Gate National Recreation Area, Marin County, California.

The project entails significant road repair and stabilization efforts. Key requirements include:
