Upscale Philadelphia high-rise now open

PHILADELPHIA—The Harman Group, now IMEG, is proud to announce the opening of Arthaus, 301 S. Broad St., Philadelphia. The exquisite, 47-story, 400,000 square-foot residential tower fits seamlessly into the atmosphere of upscale art, culture, and entertainment along the Avenue of the Arts. The luxury high-rise includes 107 condominiums, curated amenities, ground floor retail, and above-ground parking for 151 cars. A grand opening celebration was held Sept. 20.

The Harman Group, now IMEG, provided structural engineering and parking consultancy services for the project in partnership with developer, Dranoff Properties, architect, Kohn Pederson Fox Associates, PC., construction manager, and INTECH Construction.

“We have had the privilege of providing structural engineering and parking design for some of the most transformative projects in Philadelphia and we are honored to add Arthaus to our portfolio of completed projects,” said Kirk Harman, managing principal of The Harman Group, now IMEG. “We also are honored to have been able to work again with urban visionary Carl Dranoff, who is known for his ability to bring distinctive luxury projects to life. Congratulations to the entire Arthaus project team.”

Early value engineering and early investigation of alternative approaches were critical to solving the structural challenges of the project. The chosen structural system consists of cast-in-place reinforced concrete columns, shear walls, and floor slabs. The majority of the vertical structural elements are supported on shallow foundations, a mix of combined footings and a concrete mat supporting the central core. A limited number of perimeter columns are supported on deep drilled piers to avoid any impact on an adjacent historic church. Additionally, the tower has a tall, thin profile and features a supplemental damping system, a “tuned liquid damper,” to assure occupant comfort.

The Harman Group, now IMEG, also has served as the structural engineer on numerous other complex residential towers that have transformed the Philadelphia skyline, including The HarperBridge on RaceSymphony House, 1706 Rittenhouse, and more.

IMEG is a Top 5, 100% employee-owned Engineering Firm in the U.S. (BD+C) and ranked #77 on ENR’s Top 500 Design Firms list. For more information, visit imegcorp.com or harmangroup.com.
