CASE STUDYSanibel, FL Helical Pile Installation

Location: Sanibel Island, Florida
Project Type: Helical Pile Foundation for Telecommunications Tower
Client: Telecommunications Infrastructure Developer
Completion Date: March 2024

Analysis

Sanibel Island is renowned for its environmentally sensitive ecosystem and unique soil conditions. Construction projects here require foundation solutions that minimize environmental disturbance while delivering long-lasting, robust structural support.

Our team at Coastal Foundation Solutions was selected to provide foundation support for a telecommunications tower. The client required a durable concrete base foundation capable of supporting the tower’s significant load while complying with strict local environmental regulations.

Traditional foundation methods, such as deep concrete footings or driven piles, posed significant challenges due to Sanibel’s soft soils and sensitive surroundings. After thorough site evaluation and soil testing, we determined that helical piles were the ideal solution. Their ability to be installed quickly and with minimal disruption made them perfect for this coastal project.

Solution

Once contracted, our specialized crew mobilized to Sanibel Island with all necessary equipment and materials, including galvanized helical piles and extensions designed to withstand corrosive coastal environments.

We installed twelve helical piles using RS2875.217 10” x 12” x 84” galvanized round shaft lead sections and 84” galvanized round shaft extensions where needed. Our equipment allowed for precise torque monitoring, ensuring each pile reached the specified 15-ton capacity required to support the telecommunications tower.

The installation process was carefully managed to reduce noise, dust, and environmental impact. Minimal site disturbance was a top priority to protect Sanibel’s delicate surroundings and nearby properties.

Results

Our experienced team completed the installation in under one day, well within the client’s tight schedule. The galvanized steel piles offer superior corrosion resistance, essential for longevity in saltwater coastal environments.

The client was extremely satisfied with the rapid, efficient installation and the strong, stable foundation provided. The helical pile system’s capacity to quickly transfer loads deep into stable soils ensures the telecommunications tower’s structural safety even in adverse weather conditions.

This project demonstrates the effectiveness of helical pile foundations as a preferred choice for coastal infrastructure projects, combining environmental responsibility with engineering excellence.
