Abstract

An “unconventional” earth retaining system consisting of drilled underpinning piers, was used successfully to underpin a four- story building in Redwood City, California. Considerations to other conventional underpinning systems and their feasibility at the subject site are also examined. An in-depth discussion of the "unconventional" underpinning system selected for the project is presented with details of the construction sequence and difficulties encountered. Post-construction performance of the underpinning system and the relative costs of the “unconventional” underpinning system are also presented.

"Unconventional" Drilled Pier Underpinning

St. Louis, Missouri

An “unconventional” earth retaining system consisting of drilled underpinning piers, was used successfully to underpin a four- story building in Redwood City, California. Considerations to other conventional underpinning systems and their feasibility at the subject site are also examined. An in-depth discussion of the "unconventional" underpinning system selected for the project is presented with details of the construction sequence and difficulties encountered. Post-construction performance of the underpinning system and the relative costs of the “unconventional” underpinning system are also presented.
