October 16, 2013 HDR Alaska, Inc. 2525 C Street, Suite 305 Anchorage, Alaska 99503 Attn: Mr. Paul Witt, P.E. RE: PRELIMINARY EXPLORATION RESULTS, GLENN HIGHWAY WIDENING,

EAGLE RIVER, ALASKA

This letter transmits the attached boring logs and Site Plan, which provides approximate boring locations. Be advised that the boring data as presented is preliminary from field observations and may be subject to modification after completion of our laboratory analyses, which will provide additional sample information. We advanced 16 borings along the proposed widening alignment south of Eagle River and at proposed north and south pier and abutment positions at the proposed Eagle River bridge site. We also drilled four borings at the Hiland Road overpass and two borings at the Artillery Road overpass, as shown on the Site Plan, for a total of 22 borings. In each of the borings, Standard or Modified Penetration Test drive samples (depending on the particle sizes that were encountered) were taken at 5-foot intervals. The soil samples were sealed in air tight containers and transported to our laboratory for testing, as necessary. In each of the four borings at the bridge, we installed casing to facilitate shear wave velocity measurements after drilling is complete. In general, the casing consists of 2-inch, flush-threaded PVC piping that is grouted into the boring and protected with an above-ground steel monument. Laboratory tests are being performed on soil samples to evaluate the material and foundation behavior characteristics of the material encountered. ASTM International procedures are generally being followed for all soils testing.
