Modera Prominence

This project is located in the heart of the Buckhead office district at the corner of Lenox Road and Piedmont Road. The complex features 319 residential units totaling 367,000 SF, 41,700 SF of retail space, 560,000 GSF of 5-story Type IIIA residential above Level 1 and Level 2 podiums.

Permanent soil nail walls and CIP retaining walls allow for two levels of parking below grade. A large plaza with prominent landscape features along with retail caps the parking levels. Above the plaza level are PT podium slabs with five levels of Type IIIA construction for the residential units. An elevated pool and amenity deck makes up a portion of the Level 2 podium above plaza.

Each residential unit at the top level has access to a private rooftop terrace, which required a considerable amount of effort between the team members during the design phase to ensure that the terraces was coordinated with the other disciplines and met the owner’s budget and vision.

The second phase in the Modera Prominence residential development contains three residential buildings all directly adjacent to one another. In total, the high-rise contains 266,462 SF in 181 Units, the mid-rise consists of 203,396 SF in 214 units, and 119,508 SF of parking space.

The first building is a 21-story high-rise concrete frame, utilizing post-tensioned concrete slabs, braced with ordinary reinforced concrete shear walls. The building is supported on concrete caissons, drilled down to competent rock as well as rock footings bearing directly on competent rock. There is a pool/amenity deck at the 21st floor, and a large steel frame architectural feature spans over the roof at the 22nd floor. The second building is a 5-story concrete frame, utilizing post-tensioned concrete slabs and columns for lateral stability. The columns are supported on shallow spread footings bearing on soils improved by rammed aggregate piers. This parking structure supports five levels of Type III wood-framed residential construction above and is located directly adjacent to the Prominence office tower and parking deck. EM Structural coordinated the new parking and residential structure with the existing building’s foundations and site walls. The third building is a 5-story Type III wood-framed residential structure, supported on a conventional slab on grade. The wood framed buildings have units at the top floor with rooftop terraces, which required extensive coordination between architectural and structural design teams.
