Asphalt Paving – Various Locations Mount Rainier National Park P17PS01892

SCOPE OF WORK

PROJECT LOCATION AND SCOPE

Mount Rainier National Park requires asphalt overlay in two locations throughout the park to include sections of the White River/Sunrise Road, and utility trenches in the Cougar Rock Campground and Longmire Maintenance area. The Longmire area location will be an Optional project, if work in the trench has been completed timely.

Project Location and Scope: White River Road

The location of this project is on the White River/Sunrise Road, located 44 miles south of Enumclaw. The road begins at the intersection with Washington State Highway 410 and runs 15 miles to Sunrise within Mount Rainier National Park. The asphalt work is located within the first one and a half miles of the beginning of this road at the junction with Highway 410. The work will take place in multiple areas to be overlaid with an approximate total area of 16,800 square feet and approximately 305 tons of asphalt required. Two areas will be asphalted. One is approximately 165’ x 11’, a single lane of the road. The other site is approximately 575’ x 22’ that will require areas of grinding. Some sites may require a pre-level layer. The scope of work is to grind existing asphalt in areas where needed, clean the surface and apply tack coat and overlay two inches of HMA class ½” commercial asphalt. Tamp and seal all edges/joints as needed with AR4000. The Park staff will provide trucks and drivers for the hauling away of grindings.

Project Location and Scope: Cougar Rock Campground

The location of this project is in the picnic area of Cougar Rock Campground. Cougar Rock CG is located on the southwest corner of the park. Access to the Camp ground is from SR 706. The campground is located eight miles inside the Nisqually Entrance Gate. The contractor shall install an asphalt patch on the utility trench cut in the picnic area parking lot. Park crews will backfill, tamp and accomplish all preparatory work prior to asphalting, providing a three inch deep trench. The patch dimensions are approximately 1,120’ long x 5’ wide x 3” deep (approximately 102 ton) and 60’ long x 6’ wide x 3” deep (approximately 7 tons). The contractor shall pave the trench with HMA Class ½” Commercial Asphalt, tamp and seal edges with AR4000. Additionally, place asphalt patch on sidewalk area beyond the wooden curbing leading to the Comfort Station - approximately 4' by 16'. A site visit is strongly encouraged.

Optional Project Location and Scope: Longmire Maintenance Area

Longmire Maintenance Area is located on the southwest corner of the park. Access to Longmire is from SR 706 and is located six miles inside the Nisqually Entrance Gate. The contractor shall install an asphalt patch on utility trench road cuts. Park crews will backfill, tamp and accomplish all preparatory work prior to asphalting, providing a three inch deep trench. There are two utility trench cuts to be asphalted. The patch dimensions are approximately 140’ long x 5’ wide x 3” deep (approximately 14 tons) and 195’ long x 5’ wide x 3” deep (approximately 19 tons). The contractor shall pave the trench with HMA Class ½” Commercial Asphalt, tamp and seal edges with AR4000. A site visit is strongly encouraged.

If the option is awarded, the work will be performed at the same time as the work at the other two locations.
