Carr City Centers Venue

GPI designed extensive renovations, repair, and additions to the existing 12-story post-tensioned and mild-reinforced cast-in-place concrete hotel and convention center, including north and south plaza parking decks, originally built in the early 1970s. The tower renovation included the addition of a structural steel-framed story and rooftop terrace/lounge to the existing roof, removal/reinforcing of existing shear walls, and addition of new shear walls to create a more efficient floor plan, plus repair of various existing concrete issues and deterioration located throughout the tower structure. A three-story portion of the tower was removed at the rear of the building and a new plaza area on the first floor was designed to provide access to the Mount Vernon Trail. The additions and modifications to the existing tower led to the upgrade of the existing lateral system and foundations to meet the current code-required lateral loads.

The project also included the replacement of the single-story post-tensioned slab parking deck, located to the north of the tower, due to existing deterioration and to accommodate the new loading requirements of 20 new four-story townhomes, firetruck access, and various landscaping features. The single-story post-tensioned slab parking deck, located to the south of the existing tower, was repaired, and reinforced with a new composite structural topping to support 21 new four-story townhomes and various landscaping features.
