Once completed, the luxury residential tower will further establish Philadelphia’s Avenue of the Arts as one the most desirable urban communities in the world

 Philadelphia, PA – The Harman Group (THG), a firm specializing in structural engineering and parking planning and design celebrated the topping out of Arthaus with developer Dranoff Properties on February 12, 2021. The 47-story, 400,000 square-foot, residential tower located at Broad and Spruce in Center City will include 108 condominiums, ground floor retail, curated amenities and above-ground parking for 140 cars.

The Harman Group provided structural engineering and parking consultancy services to developer Dranoff Properties working in collaboration with Kohn Pederson Fox Associates, PC., construction manager, INTECH Construction and mechanical/electrical engineer Alderson Engineering, Inc.

The structural system used on the project 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 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.

“Carl Dranoff is known for his ability to bring distinctive luxury projects to life and we are proud to share this significant milestone with the entire project team,” said Kirk Harman, President at The Harman Group. “The Harman Group has had the privilege of designing complex structural systems for some of the most transformative projects in Philadelphia and we are honored to add Arthaus to our roster.”

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