Join us at the Arch Street Meeting House in Philadelphia for this two-day workshop!
Brought to you by 
APT's Technical Committee for Materials and the APT Delaware Valley Chapter

Have you ever been required to perform materials testing for a restoration project, but were unsure what to do with the results? Have you been involved in a complex project where testing would have been helpful, but were unsure where to focus your efforts and your limited budget? Have you wondered where you were supposed to learn all of this technical information in the first place?

If so, join your fellow preservation professionals for an impartial, educational conversation about these and other questions related to materials analysis. It is designed to bring together contractors, designers, conservators, and materials analysts for a frank discussion of the benefits and limitations of materials testing. 

The workshop will use Historic St. George’s United Methodist Church, located just feet from the rumbling Ben Franklin Bridge, as a case study. Participants will collaborate with their peers and the workshop’s leaders to assess conditions within the 260-year-old church, determine what types of materials testing would be most helpful in designing a restoration, learn to integrate archival materials, and develop a testing program and budget.

This workshop will thoughtfully approach using materials analysis to inform preservation design. Through presentations with integrated case studies and practice, participants will explore universal issues related to materials testing. Specific topics will address: materials testing philosophy and methods; necessary research and survey before testing; sampling considerations; strategies for efficient data collection; the testing process and standardization in testing; interpretation of test results; communicating with the project team; data interpretation and using the results; and cost, budget, and schedule.


Learning Objectives

  1. Understand the process of developing a thoughtful testing program including collaborative input from the Project Team: Owner, Architect, Conservator, Scientist, and Contractor.

  2. Explain what factors contribute to the selection of specific types of testing based on the observed conditions, client needs, project objectives, schedule, and available budget.

  3. Understand how to develop appropriate questions that materials testing can answer as they relate to the project, building and materials.

  4. Apply various approaches for testing, sampling, scientific processing and interpreting obtained data and communicating results and recommendations to the Project Team in lucid and useful reporting to move a Project forward.
