one riversidePhiladelphiaDranoff Properties celebrated the topping off of One Riverside, a $90 million condominium community in Philadelphia.

The Harman Group, a firm specializing in structural engineering, parking planning and design and construction engineering, handled structural engineering and parking consulting services on the 82-unit project.

“Working closely with Dranoff Properties and Cecil Baker, we were able to create a premier luxury condominium building that adheres to the architect and developer’s unique vision,” Malcolm Bland, The Harman Group’s vice president and principal, said. “This is the second successful project that Dranoff Properties and THG have completed, with two other projects in design. It is also one of many successful projects that Cecil Baker + Partners Architects and THG have created, which speaks volumes about our ability to design projects that get built.”

At 22 stories tall, One Riverside is the first ground up luxury high-rise condominium constructed in Philadelphia since the real estate downturn in 2007.

The property features luxury amenities including a 60-foot indoor pool, a Club Room with catering and a fully-equipped business center, landscaped terraces including a lush private garden, an outdoor sundeck overlooking the Schuylkill River and covered underground parking

The design included bringing exterior columns to the interior, and allowing for floor-to-ceiling windows. Additionally, because of the project’s location in the Schuylkill River flood plain and with the high water table at the site, occupied spaces of the building were elevated above the flood plain, with the underground parking garage located below the water table and below the flood plain. The podium, which is partially underground and contains the parking area, was designed to resist hydrostatic pressure via the use of rock anchors and a pressure raft.

According to Bland, cast-in-place concrete was chosen for the structural frame to maximize the ceiling heights and maintain a sleek modern look to the building. The concrete frame attained the required column grid spacing economically and provided a robust lateral wind and seismic force resisting system.
