Fan Pier Buildings A & B

Patriot Place

Location: Boston, MA
Owner: Turner Construction Company

roject Vaule: $27,153,883.00

The Fan Pier project required removal of 400,000 ton of soil for a new office building and parking garage. The depth of excavation was up to 40ft below street grade. The site is located on the South Boston waterfront at the location of historic wharves and slips, which were filled in and buried, over the course of time. Installation of lateral earth support for this project was a challenge due to these buried wood pile supported granite block seawalls and rubble fill. In some areas, the old granite fill was up to 35ft below street level. A steel sheetpiling cofferdam was installed, using a combination of soil tiebacks and interior steel braces (rakers) to support the sheetpiling. Removal of the very deep obstruction was performed using the Slurry Excavation method. This project was also challenging due to a very aggressive schedule. Excavation rates of up to 3000cy per day were achieved. Up to 130 trailer loads of soil per day were hauled, while maintaining access for the adjacent downtown Boston businesses..
