The Sage

Located in National Landing community in Arlington, VA, the Sage is a 20-story, 213,000 sf mixed-use building with 251 residential units, ground level retail, and three levels of below grade parking totaling 73,000 sf. Building amenities include a lobby lounge, fireside lounge, library, entertaining space with kitchen, pet spa, roof deck with fireside seating, and a state-of-the-art fitness center. The building’s exterior façade utilizes an aluminum composite metal panel rainscreen along with prefabricated stud wall panels.

One of the challenges presented to the design team was ensuring that a large concrete encased duct bank adjacent to the site that needed to remain would not be impacted by either excavation or construction. The duct bank is supported on caissons, which were incorporated into the support of excavation plan by the design team. The final location of the foundation walls was adjusted to accommodate the duct bank once its location was field verified.
