The retrofit for Olin’s McIntosh plant required SynchroPile™ Post Grouted Drilled Shafts. 31 SynchroPile 36” Post Grouted shafts 185’ deep were designed with 90 feet of steel casing. After installation of reinforcing cages, distribution plates were installed to facilitate grouting the shafts after installation. O-Cell load testing verified shaft capacity and the post grouting criteria. All of the shafts for the retrofit program were installed in areas as narrow as 14’ within operating areas of the facility.
