Abstract

Due to severe right of way restrictions associated with the relocation and widening of Interstate 85 in Atlanta Georgia, a special post-tensioned caisson retaining wall was constructed within 12 inches of an adjacent parking garage and office building. National Foundation Company's design for the twenty foot high retaining structure was used in lieu of an L-shaped cantilevered concrete retaining wall that required extensive temporary shoring for construction. The caisson wall was instrumented and monitored during and after construction using slope indicators and optical survey.

Post-Tensioned Caissons Permit Interstate Construction: A Case History
