GETTING UNDER THE SKIN OF OLD BUILDINGS

by Mark Liebman Mark and his son Alec are leading exponents of high tech forensic work on old buildings in the US. Mark will introduce you to the array of tools available to the preservationist:  Water Penetration test equipment, Infrared thermography, Ground Penetrating Radar, Laser Scanning - to name but a few. Sounds pretty daunting - but these non-destructive tools allow the preservationist to understand the state of a building and make much more informed decisions about how to preserve a building. Mark has used some of these techniques on buildings in Port Townsend - City Hall and the County Courthouse. Admission by at-will donation to our new non-profit. Presentation at:
