Case Histories

CHANCE® Helical Pile Underpinning


Castle Hills

Castle Hill Helical Pile Installation

Castle Hills

Project

Project is new construction, residential. Single family structure. Underlying soil conditions required casing of the drilled concrete piers. This proved to be too costly in terms of dollars and time. CHANCE® helical piles proved to be the most efficient technology (vs. drilled, cased concrete piers). Project was conducted in an existing neighborhood which challenged David Weekley with minimal disruption. As far as pier locations, CHANCE helical piles were installed at the same design locations as the concrete drilled shafts. Ultimate capacity required per pier: 25 kips per pier.

Castle Hills

Solution

Products used in installation: CHANCE SS5 family including an 8’ & 10’ lead section with a standard new construction bracket. 33 piers were installed in a total of 3 hours (vs. 7 days that was estimated using drilled shafts).

Key Benefits

The overall install was expedient, cost-effective, and quiet (much attributed to the installation method which minimized the equipment required for installation and associated mobilization).
