Super Piles Revitalize Boston Landmark

Boston's Landmark Center, a historic site in the Fenway neighborhood, is undergoing a major transformation. Originally built in 1928 by Sears, Roebuck & Company, the building is being repurposed into a mixed-use development that will breathe new life into the structure while preserving its historical significance. A key aspect of Historic photo of Bo this project is the deep foundation system, which employs drilled micropiles. While these have been commonly used on construction projects for the past several decades, these truly "super piles" pushed con- ventional limits of both drill depths and working capacity in order to meet the project's requirements. The installation of these micropiles presented several challenges, from extreme depths and high capacities to tight timelines and complex site conditions. This article explores the engineering feats, challenges faced and innovative solutions that were developed and implemented throughout the process. Thanks to creative problem-solving and collaboration with the wider pro- ject team, Phoenix completed its work as a geostructural subcontractor ahead of schedule. The Landmark Center has a rich history in Boston's Fenway neighborhood. Before the present building was constructed almost 100 years ago by Sears, the site had been home to a number of factories, warehouses and other industrial buildings dating back to the late 1800s. The location was also near the former Fenway Railroad Yard, a modest transportation hub that served the surrounding area at the turn of the 20th century.
