One Riverside,
Philadelphia, PA

Waterfront living in the city

The Harman Group provided structural engineering and parking consulting services for One Riverside , a 168,000 square foot, 82-unit residential condominium complex in Philadelphia. Standing 22 stories tall, the cast-in-place concrete luxury residential building features studio, one- and two-bedroom apartments, a ground floor lobby and amenities.

To ensure the best possible residential spaces, the exterior columns were brought to the interior, allowing for floor-to-ceiling windows which offer unobstructed views of University City, Center City and the Riverfront. The project also 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; a café and two levels of covered underground parking, with 110 spaces, as well as a drive-up motor court.

Due to 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.

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.
