 TYPE OF CONSTRUCTION:  Tunnel Restoration, Resurfacing, Waterline, Sanitary Sewer, Culvert Cleaning and Lighting.

 PROJECT DETAILS:  CA FTNP GOGA PRES 1(15) Golden Gate N.R.A. Tunnel Preservation

 This project is located in the Marin Headlands area of Golden Gate National Recreation Area, Marin County, California.  The project will include preventative maintenance, lighting system replacement, and waterline and sewer line replacement in the one-way, 2,362 foot long Baker-Barry Tunnel, and pavement preservation on 0.12 miles of roadway, parking area resurfacing and rehabilitation, and culvert cleaning on the CA FTNP GOGA PRES 1(15).  Work is included on Bunker Road (including the Baker-Barry Tunnel), Field Road, Mitchell Road, and within the YMCA parking lot in the Marin Headlands

 The project requires specialized, highly technical work within the tunnel including polyurethane resin injection, coring/pressure grouting, shotcrete application, removal and replacement of the existing lighting system with an LED lighting system, and removal and replacement of the existing wall mounted waterline and sewer line.  The LED lighting system will include an addressable energy management system allowing for individual control and monitoring of each luminaire and dynamic dimming of daytime luminaires to correspond to ambient light levels on both the inside and outside of the tunnel within seven daytime zones for each travel direction.

 Principle work items include 35,000 pounds of polyurethane resin injection, 3,500 square yards of shotcrete, 400 linear feet of coring/pressure grouting, 200 ceiling mounted tunnel LED luminaires, 12,500 linear feet of conduit, 2,500 linear feet of 8-inch plastic sewer line, 2,500 linear feet of 10-inch PVS waterline, cleaning 20 culverts, and 900 tons of hot asphalt concrete pavement.

 All of the work is occurring in or adjacent to cultural and natural resource sensitive areas in Golden Gate National Recreation Area, and great attention to detail will be required in achieving customer satisfaction in areas of tunnel maintenance, lighting installation, waterline and sewer line installation, quality control, and timely completion of work.  Construction phasing and temporary traffic will be very important to minimize disruptions to park visitors throughout construction. 

 The estimated price range is between $4,000,000 and $7,000,000. The anticipated advertisement date is July 27, 2016.  Construction is anticipated from October 2016 through February 2017.
