Geotechnical Engineering


33nd Northwest Geotechnical Workshop

2007 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 Idaho Transportation Department, September 3 - 6, 2007 in Coeur d'Alene, Idaho. This year we had participants from 11 State DOTs, the FHWA Resource Center, CFLHD, WFLHD, FHWA Division offices, USFS, BLM 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 included a 1-day field trip to see geology, natural hazards, and geotechnical engineering features along US 95 from Coeur d'Alene to north of Lake Pend Oreille and included a visit to the Farragut Navel Submarine Testing Facility. Presentation awards included: Best Presentation - Darin Sjoblom, Utah DOT for "Provo Canyon: To (Project From) Hell and Back"; Best Technical Presentation - Bob Kimmerling, PanGEO and Bill Hegge, Washington State DOT for "SR-539 Nooksack River Bridge" and Project From Hell - Mike Schulte, Wyoming DOT for "Year 2000 Project From Hell, Part V". The final agenda for this meeting is attached.

The 2007 Mr. Northwest Geotech award recipient was Darin Sjoblom, Utah DOT. The 2007 Hat's Off Award recipient was Bill Capaul, Idaho Transportation Department.

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 Utah DOT, October 20 - 24, 2008 in Springdale, Utah. The fieldtrip will cover geological and geotechnical features in and around Zion National Park.
