A new Boardwalk access ramp was being constructed at 29th street and the beach in Avalon, NJ. The proximity to the overhead electrical and telephone wires caused safety concerns with driven timber piles so helical piles were specified as an alternate to mitigate this concern.
- Helical Pile Type: 3.5″ round shaft helical pipe piles. 1.5″ Square Shaft – Tension
- # of Helical Piles: 20-Compression; 4-Tension
- Location: Avalon, NJ
- Installation Depth: 20-25 Feet-Compression; 15 Feet-Tension
- Ultimate Pile Capacity: 70 Kips-Compression; 50 kips-Tension
- Equipment Used: Large Excavator, 30K Drive Head
- Challenge/Unique Aspect: Helical piers are a segmented piling system, installed in sections so there were no issues with overhead wires. The excavator never needed to come close to the overhead wires as the piles installed were in 7′ and 5′ increments avoiding any safety concerns.
- Engineer/Architect: Miguel Mota P.E.
