"Geotechnical Investigations for Above-Ground Electric Transmission Structures in New England"

Gary R. McAllister, P.E., Terese M. Kwiatkowski, P.E.

This paper discusses goals and challenges to be considered in planning a geotechnical investigation program for the design of high voltage and extra high voltage overhead electrical transmission line structure foundations in New England, based on practical lessons learned on recent projects. The topics presented herein are not necessarily unique to overhead transmission projects or to New England; however, in combination, the topics help illustrate the scope and key objectives of a successful exploration program, which may be distinct from general building, transportation, and other infrastructure projects in other locales.
