SYNC at Perimeter

This project features 423 residential units, over 395,000 SF of gross rentable residential area and over 12,000 SF of retail. It includes two residential buildings, each with 5 stories of Type IIIA wood-framed construction on top of post-tensioned concrete frames. The podium slabs are braced using ordinary reinforced concrete moment frames between the podium slabs and supporting cast-in-place columns. Columns are supported on shallow spread footings bearing on soils improved by rammed aggregate pier soil reinforcing.

Both residential buildings have a precast parking deck. The Building 100 parking deck is supported on shallow spread footings bearing on soils improved by rammed aggregate pier soil reinforcing. The Building 200 parking deck is supported on spread footings bearing directly on partially weathered rock.

Due to the proximity of the new residential buildings to the existing parking decks servicing the Palisades Office Tower, E+M Structural faced unique design challenges to provide adequate foundation supports for the new residential buildings without affecting the existing parking decks for the office tower.

Downtown South – North Building

Downtown South – North Building is a 5-story mixed-use project in downtown Raleigh, NC that is in the initial design phase. This type III wood framed project includes 288 residential units, with up to 12 unit types including ADA unit modifications, with an internal, multi-story pre-cast concrete parking deck for approximately 450 spaces.  

Amenities will include a 5,000 SF clubhouse, leasing offices, business center, a centralized courtyard with on-grade pool.

Fenton Mixed Use

Fenton is a multi-building mixed-use development that is planned on 92 acres of Cary Town Boulevard on the west side of the intersection with I-40. EM Structural was in charge of the design of twelve buildings, totaling 850,000 SF, and three precast standalone parking garages. The buildings are framed of structural steel, cast-in-place concrete and type IIIA wood construction.  

Five of the buildings are single tenant, single story structural steel construction. One building is single story structural steel with multiple retail tenants. Two buildings are multi-tenant steel construction for office and retail use. Two buildings are three stories of structural steel office space on top of a cast-in-place concrete slab covering retail tenants. One building includes a roughly 110,000 SF cast-in-place post-tensioned concrete podium supporting 350 apartment units framed in type IIIA wood-framed construction. One building is split into three uses and framed in structural steel. This building includes a movie theater, a restaurant and the administrative offices for the complex.

Modera Prominence 1

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.  

Modera Reynoldstown

This $90M project is located in Reynoldstown, an area in Atlanta, Georgia, located east of the state capital on Memorial Drive. It features a 5-story precast parking garage with amenity at the top level and 5-stories of Type IIIA residential, including loft units and units.  

At the Ground Level, there are retail spaces, leasing lobby, trash and loading dock, and the entry to the parking garage. A portion of the structure at Level 1 supports a row of residential units below a podium slab and the leasing mezzanine. Residential units begin at Level 2, some of which bear upon a post-tensioned podium slab. Level 2 also includes concrete transfer girders. Many of the residential units have either a loft unit or a unit with access to a roof terrace at Level 6.  

Multiple structural systems were employed in the design of this project, including post-tensioned concrete flat plate slabs, post-tensioned concrete podium slabs, post-tensioned beams and girders, structural steel framing, concrete columns and walls, and structural wood framing. The foundation is a combination of shallow spread footings bearing on native soils and shallow spread footings bearing on soil improved with aggregate piers.  

This project received the AIA Potomac Valley 2021 Excellence in Design Merit Award for Multifamily Architecture.  

Novel Atherton (Atherton Mill)

Novel Atherton is as rich and authentic as the neighborhood itself, a storied community that celebrates Charlotte’s South End history and future of industry, innovation, and creativity.  

Located in the heart of Charlotte’s historic and upscale South End District, Novel Atherton adds 346 uniquely styled apartment homes across six-stories and over 115,000 SF of street side retail to the retail hub and community gathering place that is Atherton. It also features three elevated resident amenity courtyards with pool deck overlooking retail drive. Novel Atherton involved the integration of a type 1A cast-in-place concrete podium structure, a type 1B precast parking deck and type IIIA wood framed residential structure. It also includes a concrete ordinary reinforced concrete shear wall lateral resisting system, post tensioned concrete transfer podiums at three unique levels, and meets seismic design category C structural requirements. 

Parkview on Peachtree

This mid-rise, multifamily residential project is located at the intersection of Peachtree Industrial Boulevard and Clairmont Road in Atlanta, GA. It consists of two residential buildings, a 4-story parking deck and a structural steel pedestrian bridge. Both buildings are 4-story Type VA multifamily residential construction. The majority of the wood framing bears on conventional concrete slab on grade, though there are two post-tensioned concrete podium slabs support three levels of wood framing above. Several retail spaces are provided below the podium slabs. The foundations supporting the two residential buildings are shallow spread footings on native soils and/or engineered fill. However, a portion of the site required the use of rammed aggregate piers to remediate on-site soils. The precast parking deck is also supported on shallow foundations on rammed aggregate piers. 

113 Potomac Ave

This 683,733 SF, 13-story mixed-use development consists of a residential tower above ground-level retail, with two levels of below-grade parking underneath the entire building footprint. The residential tower includes 501 units in three wings, and the parking structure provides 253 parking spaces for retail and residential users. The ground level also includes a resident lobby and amenity space. The project utilizes almost all roof areas for amenity space, green roofs, and stormwater bioretention. The development includes two large, activated courtyards above the retail level, numerous terraces where the building footprint steps back, and rooftop amenity spaces including indoor penthouse amenities, a swimming pool, pool deck, and landscaping including an extensive green roof.

Morrison Yard

This $112M project for owner Woodfield Investments, LLC, is part of the Morrison Yard development located along the Cooper River in Charleston, SC. This 10-story, 738,000 SF building will be a mix of retail, parking, and residential. Parking is located across the majority of the ground and second floors and is capped by a podium structure that supports the residential floors above surrounded by exterior amenity spaces. The foundation system is precast concrete piles with pile caps monolithic with the post-tensioned concrete slab on grade. The residential units at the North side are framed of flat post-tensioned concrete slabs with concrete special reinforced shear walls and columns. The residential units at the South side are wood framed with OSB shear walls and plywood diaphragms.

Courtland at the Battery Atlanta (Battery at Braves)

This project encompasses 3 blocks of multi-use construction, including ground level retail and parking, and 5 stories of wood framed construction above. Two of the blocks have separate precast parking decks. The project is located directly adjacent to the new SunTrust Park, home to the Atlanta Braves, and is located in Cobb County, Georgia.

Each block has 5 stories of Type IIIA wood framed construction on top of a post-tensioned concrete podium slab. The podium slabs are braced using ordinary reinforced concrete moment frames between the slab and its supporting concrete columns.

The residential units above amenity spaces on top of the podium slabs are supported on structural steel/engineered lumber transfer framing to allow for open spaces.

There were many design challenges, including a post-tensioned mat foundation to limit bearing stresses for a block located directly adjacent to an existing tie-back wall adjacent to a new precast parking deck.
