Construction Update

• The Contractor mobilized to the 900 block of 1st Avenue East
• 1st Avenue East between 9th and 10th streets are now closed to regular traffic
• Staging and work areas are set up
• Steps have been taken for erosion control
• The contractor has started the installation of helical piles, which are required to support the foundation for the future boardwalk

Fun Fact:

Helical piles, also known as helical piers or screw piles, are constructed using steel shafts with helical flights of various sizes to suit site-specific ground conditions.

Common uses:

• Structural support (compression or tension) for both permanent and temporary structures
• Underpin existing foundations

Process:

Piles are generally installed using standard tracked or wheeled excavators with a torque motor attachment, which monitors the torque achieved during installation to verify the design. Multiple steel sections are connected via a bolted connection, and sections are added to complete the total pile depth.
