Revitalizing the Past for a Modern Mixed-Use Future

At Cates Engineering, we embrace the complexities of adaptive re-use as opportunities to combine innovation, sustainability, and cost efficiency. The 100 Park at Wyomissing Square project is a perfect example of our approach. Located in Wyomissing, Pennsylvania, and developed by Bozzuto Group and New Boston Fund, Inc., this project transformed an early 1900s warehouse into a thriving mixed-use residential community without demolishing its core structural foundation.

Engineering a Modern Vision on Historic Foundations

The original structure consisted of a one-story steel warehouse built atop an at-grade podium slab with a partially buried lower level. The developers envisioned removing the warehouse’s steel frame and reusing the existing concrete podium to support a new four-story, 248-unit wood-framed apartment building, while repurposing the lower level for parking. To realize this bold and cost-conscious strategy, Cates Engineering had to rigorously verify the structural capacity of the existing foundation.

Testing, Technology, and Thoughtful Design

To determine if the century-old podium slab could support the new construction, we implemented a multi-phase evaluation and design process that included:

  • Core sampling to assess slab thickness and in-place concrete strengths
  • Ground-penetrating radar (GPR) and historical shop drawings to confirm slab reinforcement
  • Finite element analysis to evaluate the structural capacity of the slab, columns, and foundations
  • Composite steel decks to repair slab openings without the need for new columns or footings
  • Geofoam fill in interior open areas to reduce added load while achieving proper grading and drainage

Each of these strategies contributed to reusing the existing structure effectively, preserving the historic footprint while supporting a modern residential complex above.

Cost Savings and Environmental Benefits

Our engineering solutions didn’t just meet design goals they also delivered significant financial and environmental value. By confirming the integrity of the podium slab and avoiding unnecessary demolition, we saved the developer millions of dollars and significantly reduced construction waste. This project is a prime example of how smart engineering can unlock the hidden value of existing infrastructure.

Built to Last Then and Now

Completed in 2009, 100 Park at Wyomissing Square remains a vibrant example of how adaptive re-use, when supported by detailed structural analysis and thoughtful design, can bring new life to underused spaces. It stands as a testament to the value of preserving what works, while building toward what’s next.
