Strict Environmental restrictions for construction in the sensitive wetlands, required compliance with the Wetlands Preservation Act which was enforced by the both the SANDWICH CONSERVATION COMMISSION and Mass DEP.
Project Summary:
- Helical Pile Type: IDEAL 2 7/8″ Pipe Piles (203 wall)
- Location: Sandwich, MA
- Helix Plates/Ultimate Pile Capacity:10″ 12″ 14″ / 15 Kips – Compression, 15 Kips – Tension
- Equipment Used: Mini-Excavator Fitted with a Hydraulic Torque Head & Portable Handheld Hydraulic Anchor Driver.
- Challenge/Unique Aspect: Strict compliance with Mass Wetlands Preservation Act required no disturbance or impact to sensitive wetlands. Mobilization challenges required portable hand-held equipment in some areas to avoid intrusion into this sensitive environment. Potential uplift from flooding or a storm surge required a tension load test as well.
