APT Delaware Valley Chapter Symposium: Building Resilience and the Evolving Role of Preservation Technology

📅 October 2-3, 2026
📍Kleinman Energy Forum, Fisher Fine Arts Library, 220 South 34th Street, Philadelphia, PA

The University of Pennsylvania Stuart Weitzman School of Design and the Association for Preservation Technology-Delaware Valley Chapter (APT-DVC) present a one-day symposium focused on the subject of building resilience, referring to both the structures that demonstrate this quality and the actions needed to ensure it in our built environment. How have so many buildings survived, and thrived, for so long? What can we do to ensure their continued survival and relevance?

Focused on the historic built environment of Philadelphia, we will present a series of speakers, panel discussions, and case studies that will define what we mean by building resilience, particularly as we look to a future with a rapidly changing climate. Presentations will include multiple investigations of resilience, providing attendees with an understanding of the concepts and the tools to carry them forward.

Submitted for AIA Continuing Education credits approval.

🔔 TOMORROW ~ APT WEBINAR ~ Digging up Dirt: A Review of Best Practices in Cemetery Conservation

🗓️ Tuesday, August 25
🕑 2 - 3 p.m. ET

Join APT International and Association for Preservation Technology, Northeast Chapter for the second of two webinars this summer.

Like many areas of historic preservation, the means and methods of grave marker restoration have evolved over time. The use of restoration materials such as ferrous metals and pure Portland cement repair mortars has changed as new information was gathered, and their long-term damage understood. In other cases, we’re realizing that the old practices were better: bronze pins rarely require replacement, and many conservators are going back to lime-based repair mortars. Even in the short span of 23 years as a conservator, Stephanie has seen pins go from stainless steel, to fiberglass, and back to stainless steel.

This presentation will look at the evolution of the means and methods of cemetery conservation and how they have changed over time. It will also serve as a review of repairs made by the speaker over the course of the last two decades as a conservator, and share some of the lessons learned where things went smoothly, and, more importantly, where they didn’t, and what was done to make it right.
