Located in the City of Detroit where New Center and Midtown meet, this project provides five levels of residential space along with an additional level of retail space facing historic Grand Boulevard. The upper five levels of load–bearing, cold formed steel sit atop two full levels of concrete framing. An interstitial, concrete mezzanine between the first and second levels offers additional parking, and the lowest level of the structure is completely below grade, providing sheltered parking for the building’s residents. 

Both post-tensioned and mildly reinforced concrete floors are used throughout the project. Two-way, flat–plate, post–tensioned concrete slabs frame the parking areas and provide a podium for the upper cold formed framing. The podium level also incorporates stage-stressing into its design to reduce the requirement for mild slab reinforcement. The retail areas employ two-way, flat-plate, mildly reinforced slabs to accommodate variability in future uses.

The panelized cold formed walls support Ecospan™ composite floors.   

The Ellis, also known as Market 42, is a mixed use project in the heart of Charlotte’s First Ward District.  This two-phase project consists of 549 apartments between a 33-story, 375 ft. tall concrete framed high rise and a six-story mid-rise which will be timber framing over a concrete podium.  There will be approximately 20,000 square feet of retail and a precast parking garage as well.

This pair of 5-story residential structures is located in Sandy Springs, Georgia.  It is part of a larger overall development that includes a performing arts center, parking structures and stand-alone retail.

Both buildings are Type III multifamily residential construction.  The majority of the wood framing bears on conventional concrete slab on grade, though there is a post-tensioned concrete podium slab in one building that supports four levels of wood framing above.  Several retail spaces are provided below the podium slab.

The foundations supporting the two residential buildings are shallow foundations on native soils and engineered fill.  However, a portion of the south building footprint occurs directly over a subterranean parking structure (designed by others).  For this reason, two expansion joints were provided in the wood framing to allow for differential movement at the foundation level.

The project consists of 265 apartment units in a five-story, wood framed building wrapping around a precast parking garage.  The development also features a pool, fitness, game room, common areas, and ground level retail.

The structure is Type III wood framing with wood floor and roof trusses spanning between wood framed bearing walls.  A cast-in-place, post tensioned concrete podium slab with concrete columns was incorporated to create larger open spaces at the ground level to accommodate amenity and retail functions.  OSB and gypsum sheathed wood framed shear walls resist lateral loads.  The structure bears on shallow concrete spread footings on soils improved with rammed aggregate piers.  The ground level retail required extensive tall storefront detailing and structural support for large brick openings and canopies.

This 21-story mixed-use structure is located Uptown
Charlotte, North Carolina across Stonewall Street from
the NASCAR Hall of Fame.

Level 1 has multiple residential spaces, the largest of
which will be home to Whole Foods. The basement, a
portion of Levels 1-8 and Level 9 are dedicated
parking for retail and residential. Residential units
are provided at Levels 3-7 (wood-framing) as well as
Levels 10-19 (high-rise). Residential amenity spaces
are provided at Levels 3, 10 and 19.

Multiple structural systems were employed in the
design of this project, including post-tensioned flat-plate
slabs, post-tensioned beams and girders,
composite structural steel framing, concrete columns,
concrete shear walls, and structural wood framing.
The foundation for the structure is a combination of
shallow spread footings bearing on rock and concrete
drilled piers.
