Replacing the old Pier 1 Import/Office Depot retail complex at 4455 Connecticut Avenue in Van Ness, this high-rise residential building includes 273 apartments (ranging from studios to three bedroom units) with a total of 11-stories: six above-grade residential levels and five below-grade residential levels along the rear of the property overlooking Rock Creek Park. The project also includes 9,000 sf of restaurant and retail spaces on the ground level and 226 parking spaces in an underground garage.
The above grade residential tower is constructed of two-way post-tensioned flat plate concrete. A below-grade parking structure consists of a poured-in place conventional concrete slab. ETI served as the Special Inspections Engineer-of-Record for the project. Our scope of services included various inspections of the earthwork/foundations, excavation support, structural concrete, architectural and structural precast concrete, masonry, structural steel, cold-formed metal framing, fireproofing, waterproofing, roofing, and building envelope.
