CPTu Investigation & Helical Pile Design for Pier

Swanquarter National Wildlife Refuge, Hyde County, North Carolina

InnovoGeo Engineering performed advanced in-situ cone penetration testing with pore pressure measurement (CPTu) soundings for a new design-build project for the U.S. Fish and Wildlife Service.  The project involved the realignment, extension, and rehabilitation of an existing timber pier. From signed contract to final geotechnical engineering report - including CPTu results and recommendations for helical pile design - we delivered the complete report in less than two weeks.

InnovoGeo’s Founder and Principal shared: “Over my career, I’ve been involved in dozens of helical pile projects, and this was the first where CPTu data served as the primary subsurface investigation method. The quality of CPTu data, and its ability to support more reliable capacity and torque predictions, is significantly greater than what is typically seen with conventional SPT borings.”

Our ability to rapidly mobilize, self-perform high-quality in-situ testing, and provide actionable recommendations helps keep design-build teams moving forward, minimizing delays and adding real value where schedule and reliability matter most.  We’re proud to support projects that showcase our capabilities while working within such treasured natural environments.
