The Ventana, located at 912 F Street Northwest, Washington DC, is a mixed-use project that includes 62 luxury condominium units and streetscape retail. The cast-in-place concrete building features a dramatic 10-story curtainwall tower that sits adjacent to three, three-story historic townhouses that total 15,000-SF. Each has two residential floors and one floor of retail. The historic buildings have been carefully restored and reviewed by the Heritage Preservation Review Board. The retail area includes a large skylight between the structures and creates an enclosed four-story courtyard behind the historic buildings. A complex fountain system and tight site presented significant challenges. During preconstruction, adjacent buildings were found to have very shallow foundations that required underpinning. Existing soils were very poor, requiring the need for bracket piles and imported backfill. DAVIS installed 170 auger cast piles below a web of grade beams and pile caps. In addition, condo layouts are not typical on all floors so careful coordination was critical due to low slab-to-slab heights, an effort to maximize the building within the limited height requirement.
