An observation tower and boardwalk were being reconstructed in Port Norris, New Jersey post Super Storm Sandy destruction. Helical Piles were selected as they are an environmentally friendly, non-invasive with minimal impact to this sensitive terrain. Installation with small, low impact equipment on marsh mats also greatly contributed to the reuse of helical piers. Art Kozoil (SJHP), who worked on the original project 20 years ago, returned to the scene of the crime.
Project Summary:
- Helical Pile Type: RS 4500 .337 Wall and 1.5″ Square Shaft
- # of Helical Piles: 27
- Location: Port Norris, NJ
- Installation Depth: 25′
- Ultimate Pile Capacity: 60 kips
- Equipment Used: 16K Drive head, Mini Excavator, Marian Torque Indicator
- Challenge/Unique Aspect: The boardwalk was constructed out of a pre-fabricated material, Permatrak concrete boardwalk system. This required South Jersey Helical Piers to be exact with their pile & bracket locations with only a 1/8″ to 1/4″ tolerance for the connecting bolt holes. Extra precaution was taken ensuring this install did no harm to the sensitive Eco-system.
