Treviicos completes slurry wall of Boulevard on the Greenway luxury condos
Treviicos has completed construction of the slurry wall foundation of Boulevard on the Greenway, a 12-story, 36-unit luxury condominium building overlooking the Rose Kennedy Greenway. The slurry wall has a maximum depth of 53 feet below the Greenway, with an average depth of 47 feet, and has a concrete surface area of 15,500 square feet. Concrete for the 353-linear-foot-long, 30-foot-thick slurry wall was poured from January to March.
Excavation of slurry wall panels at Boulevard on the Greenway hit rock bottom in June, at which point Treviicos installed a two-level internal horizontal bracing system to retain the slurry wall throughout construction. Treviicos will remove the bracing once Boulevard on the Greenway’s foundation is fully constructed and the superstructure has begun to rise in mid-September. A concrete cap beam has been nearly fully installed along the top perimeter of Boulevard on the Greenway’s slurry wall, and concrete is being chipped back from the slurry wall in order to give the wall a uniform shape. The slurry wall will enclose a Park Plus automated parking garage, a first for Boston, featuring room for 35 cars.
Located on a small, angled site in the heart of Downtown Boston parallel to the Central Artery highway tunnel, Boulevard on the Greenway’s slurry wall presented numerous design and construction challenges for the Treviicos team. With thousands of cars passing by the foundation daily, excessive vibration and prevention of wall movement were both design concerns. Thanks to the Treviicos team’s expert engineering, both of these issues have been resolved. Another challenge posed was the existing Charles Bulfinch designed facade on site, which is over 200 years old and will be incorporated into Boulevard on the Greenway’s future facade. In order to retain the facade throughout foundation construction, an elaborate joint system was installed. The following are photographs of the Boulevard on the Greenway site:
