The Calvert Apartments

SK&A provided comprehensive structural engineering services for the renovation and reconfiguration of The Calvert Apartments from a dated high-rise building, into a contemporary, mixed-use residential complex. The development features a central 16-story modernized tower with two new apartment buildings on each side as well as underground parking.

The new apartment buildings consist of four levels of post-tensioned concrete over a reinforced concrete retail level.  The first level above the retail floor is an 18” thick transfer slab.  The buildings also feature green roofs, amenities, and three levels of parking below ground.

The project totals 114,000 sf of residential space amongst the two new apartment buildings, 14,200 sf of retail space, 205,000 sf of underground parking for 522 cars and 193,000 sf of renovated residential space within the existing high-rise apartment building. The revitalization of the high-rise portion of the project was extensive and required multiple improvements, including:

• Replacement of the building’s exterior skin 
• Addition of a new roof parapet wall 
• Design of a new building entrance canopy 
• Enclosure of the existing ground level drive-through at the building entry and addition of four new units within that space
• Underpinning of the existing building foundations along the new garage 
• Replacement of the wall assembly with new curtain wall and arched roof profile 
• Configuration of a new pool
• Expansion of the existing penthouse levels
• Modification of two existing elevators 
• Addition of a new freight elevator and two new elevators to serve the low-rise residential
• Demolishment of the first floor slab within the hi-rise; the floor was reconstructed to match the first floor level of the new low-rise 
• Addition of new connection corridors between the new buildings, the hi-rise tower, and new loading dock areas
