Rock Creek Terrace Apartments, an 18-story post-tensioned concrete residential building in Rockville, MD, was an early example of post-tensioned design in the region. Completed in the 1970s, the building features private cantilevered balconies that, over time, began to show signs of corrosion and deterioration, particularly at the tendon anchorage.

‍

Project scope included conducting a comprehensive condition assessment to evaluate the integrity of the post-tensioning system, focusing on the balcony slab edges. Our assessment identified key areas of concern, prompting us to recommend a phased, systematic approach to address the deterioration. We initiated the investigation with targeted, intrusive inspections on a single balcony, using the findings from each phase to refine and develop long-term, cost-effective solutions for the entire building.

Structura’s approach enabled the restoration of the building’s structural integrity while minimizing disruption to residents. Our work has helped ensure the continued safety and longevity of this landmark residential property, providing building management with a roadmap for addressing future concerns.
