8:00 AM

Operation of Obstacle Detection GPR Designed for Use on HDD Machines

David Hanson, Vermeer Mfg. Co. and Kiran Kothari, Gas Technology Institute

This paper describes the use and test results of drillhead mounted GPR for HDD operations.

8:25 AM

Soil Response Considerations During HDD

Mathew Francis¸ PE, URS and Richard Stauber¸ PE, URS

This paper describes HDD field observations of borehole soil response conditions as they relate to recent numerical and analytical studies and provides guidance for assessing borehole stability under various soil conditions.

8:50 AM

Collins Orton, TT Technologies, Inc.

This paper deals with large diameter HDD pipeline projects and the use of pipe ramming HDD Assist techniques. Several high profile case studies are presented.

9:15 AM

HDD Design & Execution: Intersect Drill with Significant Elevation Change and Artesian In-Flow

George Taylor, Entec Inc. and Grant Jamison, Entec Inc.

This paper illustrates the application of science and technology in the effort to design a solution for one of the most difficult HDD projects ever attempted in the rugged Eastern slopes of the Canadian Rockies.

9:40 AM
