Design-build pile foundation for an equipment pad to support machinery that fabricates submarine parts (self-performed by the US Navy). Over 400 cubic yards of concrete were poured for the equipment pad which required a deep-foundation in the soft soils to support the pad and the equipment that would be mounted on it.
Project Summary:
- Helical Pile Type: STELCOR – SC 1600
- # of STELCOR Piles: 64
- Location: Philadelphia, PA
- Installation Depth: 40′
- Ultimate Pile Capacity: 55 Ton Ultimate
- Equipment Used: ProDig V50 Drive motor – Marian Digital Torque Indicator
- Challenge/Unique Aspect: The constantly cycling equipment utilized in the manufacturing process for this new facility raised questions concerning critical settlement tolerances for foundation piles. Pile Installation in a fully operational, secured Naval facility with limited access, at the bottom of a 15′ deep sheeted pit, all contributed to the decision to use STELCOR. Danbro value engineered the project using STELCOR saving time and money over the alternate plan of splicing and driving 80′ long H-Piles in an existing building.
