This project consists of 80,000 cubic yards of slag cement concrete used in all aspects of the project  from normal, high strength and self-consolidating concrete.  All mixtures used ternary powders for concrete embodied energy reduction and Carbon-Cure Technology for CO2 sequestration.  3K, 4K, 5K, 6K & 10K mixes.

Slag Cement was used for environmental benefits, plastic property enhancements, strength and durability attributes. SCC 10,000 would not be possible without the use of slag cement, silica fume trials proved too sticky and hard to place.

The project consists of a 26-story, 606,000 square foot Class A office building, 18-story, 355-unit modern residential tower atop eight levels of parking, a 12-story, 205-key boutique lifestyle hotel, 30,000 square feet of retail, and a 635,000 square foot parking deck providing 1,909 parking spaces. Rising from the north end of the Midtown tech corridor at 17th Street and Spring Street, Midtown Union will knit into the existing neighborhood fabric and leverage it into a more vibrant mixed-use place for people.

Anchored by Invesco’s new headquarters, the 3.8-acre site is currently projected to include an extension of the Arts Center Way pedestrian and retail-focused street with offices, residences, a boutique hotel, parking facility and retail. From the site, people will find new pathways that will contribute to making the area more walkable. A short walk from the site, they will find easy access to the MARTA Arts Center rail station and the 17th Street bridge to Atlantic Station and the dynamic Spring Street tech corridor. Current plans call for ample greenspace to be woven throughout the site at the street level, between the buildings and at elevated landscape decks.

The Arts Center Way street changes 26 feet in elevation as it connects between Spring and West Peachtree Streets. We turned this into an opportunity to diversify the connection points into the site by integrating all the program components. This planning approach aims to draw people to the site and to provide a variety of places for people to meet or to just linger and relax. The new and vital street is a private sector investment into Midtown that also provides a direct connection to the Woodruff Arts Center and High Museum of Art.

The project is currently under construction and is expected open in 2022. The office building component of the project is seeking LEED v.4 Silver certification.
