The Dalian on the Park apartments were built atop the Rodin Square development, a $160 million mixed-used property that sits on a three-acre plot in a busy quarter of Philadelphia. The design team for the project had utilized cold-formed bearing walls in prior jobs and were impressed by the time and cost savings they had achieved on the project. Most engineers believe six levels is the maximum effective design to be used, but engineers at Harman Group saw greater potential.
The development of the new HDS Framing System from ClarkDietrich weighed heavily in the design team’s decision to utilize the same structure for the new nine-story apartment tower. “When ClarkDietrich added punchout capability to their HDS structural studs, it allowed us to smoothly incorporate them into our wall panels, greatly improving their load bearing capacity compared to standard stud shapes. With that increased load capacity, we could engineer taller, stouter cold-formed steel structures with a lot more confidence,” said Barry Unger, president of Panel Systems, Inc., a company that engineers, fabricates and installs cold-formed framing components for walls, floors and roofs.
Design and manufacture prefabricated wall systems that would provide structural support for the nine-story Dalian on the Park apartment tower. The wall components provided by ClarkDietrich not only support nine floors of precast concrete plank, they provide the entire lateral bracing system, eliminating the need for reinforced masonry shafts or special structural steel elements. Moreover, the structural stud walls provide the backup for a significant amount of the interior drywall, saving the time and expense of an independent drywall framing operation. Importantly, the factory-made walls would also drastically minimize traffic disruptions in the bustling neighborhood since the walls would ship ready-made to the construction site.
