Two Drydock Avenue consists of driven concrete piles supporting a 225,000 square foot, 12-story commercial office building in the Raymond L. Flynn Marine Park on the edge of Boston’s Seaport District.

The building features ground-floor retail space, a 12,000 square foot public plaza, a 7,500 square foot rooftop terrace, and a fitness center. Three of the building’s 12 stories will be above-ground parking floors, housing 150 parking spaces, and the building was designed to achieve LEED Gold. The fill, organic silts, and marine clay present at the site were unsuitable for supporting this structure on shallow foundations. Therefore, driven piles bearing on bedrock were designed as the deep foundation elements to support the structure.

A total of 240 precast, prestressed 16-inch square concrete piles were installed, driven to bedrock at a depth of approximately 80 feet below ground surface. Piles were driven their full length to develop 300T resistance.
