32nd Northwest Geotechnical Workshop

2006 Executive Summary Report

As part of our technology sharing program, we are distributing this Executive Summary of the technical information presented at the subject workshop hosted by the Colorado Department of Transportation, September 24 - 27, 2006 in Breckenridge, Colorado. This year we had participants from 10 State DOTs, the FHWA Resource Center, CFLHD, WFLHD, and FHWA Division offices, and several invited speakers from private industry. A variety of technical and case study presentations were made on subjects such as slope stability, foundations, geophysics, retaining walls, and other geotechniques. The workshop was held the same week and in the same location as the Highway Geology Symposium and the two meetings shared a 1-day field trip to see geology, natural hazards, and geotechnical engineering along the Interstate 70 and US 6 corridors in the mountains of Summit and Clear Creek Counties, Colorado. Presentation awards included: Best Presentation - Mark Vessely, Colorado DOT for "Maroon Creek Bridge in Aspen - What You Can Buy for $14 Million in Aspen"; Best Technical Presentation - Mitchell McDonald, Alaska DOT and Robert Dugan, Golder Associates for "Using Innovative Methods for Geologic Mapping of a Proposed Highway Alignment"; and Project From Hell - Clifton Farnsworth, Utah DOT for "Provo Canyon Reconstruction". The final agenda for this meeting is attached.

The 2006 Mr. Northwest Geotech award recipient was Mark Falk, Wyoming DOT. The 2006 Hat's Off Award recipient was Mark Vessely, Colorado DOT.

This years Northwest Geotechnical Workshop has again proven to be our most successful geotechnical technology transfer activity. The State and FHWA personnel from the 10 Northwest and Rocky Mountain States who participate in this workshop consider this to be the best and most productive technical session they attend during the course of the year.

Next year the Northwest Geotechnical Workshop will be hosted by the Idaho Transprotation Department, September 3 - 6, 2007 in Coeur d'Alene, Idaho. The fieldtrip will cover geological and geotechnical features along the US 95 corridor north of Coeur d'Alene.
