- Description
- THIS IS NOT AN INVITATION FOR BID, PLANS AND SPECS ARE NOT AVAILABLE AT THIS TIME. THE INVITATION FOR BID IS SCHEDULED TO BE POSTED ON OCTOBER 14, 2014. PROJECT DETAILS: CA FTNP YOSE PRES 1(14) Yosemite N.P. Tunnel Preservation This project is located on Big Oak Flat Road (CA Route 120) within Yosemite National Park in Mariposa County, California. The project includes preventative maintenance work to Big Oak Flat Road Tunnels No. 1, 2 and 3. The project starts approximately 1 mile west of the intersection with El Portal Road in Yosemite Valley. The proposed work primarily consists of spot repair of damaged reinforced concrete tunnel lining, sealing leaking joints in tunnel liners, improving tunnel liner drainage to existing drainage channel along roadway, installing trench drains across roadway, coring 3 inch weep holes in existing concrete curb and removing and replacing damaged concrete roadway slabs. Tunnel No. 1 is 371 feet long with a cross section of a 14.5 foot radius arch on a five foot spring line, and an 18-inch thick reinforced concrete lining. Tunnel No. 2 is 227 feet long with a cross section of a 14.5 foot radius arch on a five foot spring line, and an 18-inch thick reinforced concrete lining. Tunnel No. 3 is 2,087 feet long with a cross section of a 14 foot radius arch on a five foot spring line, with a lining which varies from reinforced concrete to exposed rock with a thin layer of shotcrete. The project is located in Yosemite Valley within the National Park which has high visitation and sensitive resources. The tunnels are on Big Oak Flat Road which has average daily traffic of approximately 1,500 vehicles. Construction caused traffic delays will be limited to 15 minutes during daytime work and 30 minutes during nighttime work with one lane closures allowed. The project requires specialized, highly technical work within the tunnels while maintaining one lane of traffic at all times. Concrete spall repairs will require location of the actual extent of deteriorated or delaminated concrete by the contractor, including location of the existing reinforcing bars. Chemical grout injection repairs will require qualified personnel with documented previous experience. Acceptance of the grout injection repairs will be based on performance requirements for stopping leaks. All concrete pavement and spall repairs will be integrally colored to match existing treatments, and colored joint sealant will need to be provided to match adjacent sidewalks. All wash water from power washing operations will need to be contained and filtered before being discharged or disposed of. This project will require approximately 12,000 LNFT of joint and crack sealing (tunnel liner), 91,000 SQFT of tunnel cleaning (power washing), 130 SQYD of reinforced concrete pavement (at tunnel portals), 900 SQFT of concrete pavement patch (within tunnels), 50 SQFT of concrete spall repairs (tunnel liner), and 100 LNFT of coring/pressure grouting (tunnel liner leak repairs). In addition the project will require approximately 800 LNFT of 6 inch underdrain pipe installation and 2 inlets within the tunnels, and 80 LNFT of trench drains just inside the portals. This project is located in a challenging and highly sensitive location in Yosemite Valley within the National Park, and great attention to detail will be required in achieving customer satisfaction in areas of tunnel repairs, quality control, traffic control and timely completion of work. Construction is anticipated from February to May 2015. The approximate range for this project is between $1 million and $3 million.
