Case Study #01896
Project Description
Multi-story commercial building new construction – New Jersey. On the shore line a construction site required a quick and vibration free solution to achieve high capacity loads . PierTech’s Hercules piles were brought in to satisfy this requirement.
Design Description
The PierTech Hercules Piles leads were 7” (0.362wt) x 25’ pipe shaft with a 26” O.D., 1” thick helix. The extensions were 7” (0.362wt) x 20’ pipe shaft. 120 ton capacity per pile.
Construction
The PierTech Hercules piles were installed in clusters of 3 and 4. These high capacity helical piles were installed to an average depth of 60 feet and terminated on a rock-gravel strata. They were installed using a high flow excavator with a PierTech specific quick connect unit. 446 piles were installed using a PierTech 100k drive head. Once the pile installation was complete, the clusters were tied into the pile-caps and the foundation was poured.
