Case Study
Bradford Building - Gainesville, GA
Situation
In November 2024, a six-story mixed-use development project was
launched in Downtown Gainesville, Georgia, at 126 NE Bradfords
Street. The site, rich in history and previously serving as a garage,
theater, and parking lot, presented unique challenges due to its
compact size (300 feet by 80 feet) and subsurface conditions. The
area contained a hard material layer at depths ranging from 23 to 40
feet, requiring a specialized foundation solution.
Scope of Work
Cantsink LLC, alongside Forsite Engineering Group, was hired to
provide a foundation system for the building. The work involved
installing 140 grouted 4-inch piles to ensure the structural
integrity of the development. The installation required driving
approximately 9,000 feet of piles over five weeks, with some
delays due to weather.
Anchor System
The foundation was anchored with 4.5-40L07-12/14/16 Triple
Helix helical piles, each equipped with a 10.5-inch grouted shaft
designed to support loads exceeding 145 kips. The piles were
driven to depths ranging from 23 to 40 feet, with 13 piles installed
in the first section and 127 piles in the second. To address the hard
material layer encountered at varying depths, Cantsink used a
25,000 ft-lbs Prodig drive head and a large excavator to apply
additional downward force, ensuring penetration while
maintaining load-bearing capacity.
Result
The foundation installation was completed successfully, with all
piles installed to specification and within the projected timeline.
Cantsink's approach ensured the stability and longevity of the
development, addressing site challenges effectively. The project
contributed to the revitalization of Downtown Gainesville,
blending modern architecture with the area's historical charm.
