Georgia Aquarium Dolphin Exhibit Expansion

Owner: Georgia Aquarium, Inc.
General Contractor: Brasfield & Gorrie

An expansion to the existing facility at the Georgia Aquarium required the addition of an interior column with the footprint of the building. However, there existed no foundation to support the new column. The solution was to install a three micropile group in the basement level of the structure.

Access to the basement required the use of a low-headroom drill rig due to clearance restrictions. The selected rig was a Hutte HBR 203 micropile rig. It allowed the installation of a test micropile in proximity to the pile cap, as well as the production piles.
