Situation: This is a 100-year-old building that had been a school, courthouse and
theater. This project was to convert the building to a Historical Museum
for Horry County, SC. They wanted to construct a slab that would have
a crawl space below it for the interior of the building. For the exterior,
they wanted to construct a foundation for a new A/C chiller and front
Solution: Ram Jack helical piles installed to 30 kips working load were utilized
for deep foundation supports for the new suspended slab. Interior piles
had to be installed manually as there was no machine access. Ram Jack
helical piles for deep foundation support for the A/C chiller and enclosure
were installed with a skid steer.
Conclusion: The entire project was 167 Ram Jack helical pilings that went 50 - 60 ft.
deep. The majority of those were installed manually on the interior (no
machine access). Due to unpredicted access as the job progressed, Ram
Jack was required to mobilize many more times to complete the piling installation
than originally predicted. Welch Construction and Horry County were very
satisfied with Ram Jack’s ability to make unpredictable changes
in the work scope as well as the extreme manual stresses sustained by
Ram Jack’s crew to manually install these piles.
