Efficiently building a Firestone from the ground up between two railroad lines would be a challenge in itself. However, this project site posed some additional challenges that seriously threatened our timeline. A project engineer recommended 25 feet of deep sheet pile shoring to support the existing structures. However, city ordinances require 12 to 16 weeks to review any shoring that extends over 12 feet. We needed innovative ideas, or our deadline was in danger.


Gallant utilized a Geopier Rammed Aggregate Pier (RAP) system. The RAP system stabilized the existing soils while extending only to a depth of 12 feet, allowing us to bypass a lengthy review process. We were then able to use spread footings to support the new building and leave the existing soils and structures in place.


Gallant was not only able to keep up with Firestone’s aggressive schedule but also delivered $150,000 in savings to the client by using Geopier instead of the traditional sheet pile shoring.
