Vibratory Stone Column Uplift Anchor Installation at Western Carolina University

Western Carolina University
Project Overview

Western Carolina University is one of the many universities that we have been fortunate to do ground improvement for throughout the United States. At this job site, Helitech Civil Construction completed a design-build vibratory stone column ground Improvement method for Western Carolina University’s new building addition for their science, technology, engineering, and mathematics program (STEM). Because of the high dead and live load on this proposed building, Helitech was tasked to design-build a ground improvement system that would achieve an excess of 8,000 psf (pounds per square foot). By doing this, we were able to provide our clients with less than 1 inch of total settlement on this design.

Requirements & Challenges

Helitech Civil Construction’s vibratory stone column design and layout had to take the retaining walls into consideration. Not only the weight of the retaining wall, but the soil backfill and the vertical column load on that particular retaining wall. Helitech utilized uplift anchors on this because the shear walls have large net tension loads, therefore, Helitech incorporated in its vibratory stone column design uplift anchors to reduce and take away any and all net tension load on these shear walls.



Solution & Results

Helitech Civil Construction’s engineering team was able to design-build a cost-effective solution that was able to save our client time and money.

Project Details

Helitech provides ground improvement services; either vibratory stone columns, vibratory concrete columns, earthquake drains and or concrete modular columns in the Southeast. Helitech Civil Construction has a new location based in the Raleigh, North Carolina area. This particular location services Virginia, North Carolina, South Carolina, Georgia, and Alabama and we are proud to be continuing that growth by working at Western Carolina University.
