Documentation can comprise many layers of information from various sources, relying on visual assessment and physical measurement in many cases. What tools are available to preservationists when there is a requirement to understand construction arrangement and condition below the surface? This symposium is designed to introduce the audience to the variety of technologies available, describing the fundamental methods for collecting and analyzing data and taking a look at the limitations of those tools in real word applications. Topics covered will include Ground Penetrating Radar, Infrared Thermal Imaging, Ultrasonic and Magnetic Testing, Laser Scanning, Photo-documentation and Backscatter X-ray Imaging.
Registration is required. Additional information can be found here.

Alan White is the Director of Operations for GB Geotechnics USA Inc. (GBG), with almost 20 years of preservation experience, ranging from hands-on restoration of medieval properties in the UK to implementation of emerging technologies for the non-destructive evaluation and measured survey of historic structures across the US. With a background in engineering (University of Hertfordshire, UK, BEng. (Hons.) and expertise in data collection & analysis (10 years’ experience with GBG), he specializes in the documentation of the built environment, providing highly accurate and detailed construction arrangement and condition assessments. Located on the West Coast, he serves on the Board of the APT Western Chapter and is actively involved with the California Preservation Foundation.
Aldo De La Haza joined Dynasty Group with more than 20 years experience in the nondestructive testing (NDT) of concrete. Mr. De La Haza has extensive project experience throughout the Unites States and internationally. He has applied NDT test methods to solve unique concrete related problems on hundreds of project assignments, including: bridge investigations, façade investigations, historic preservation, structural collapse investigations, and criminal forensic investigations. Throughout his career, Mr. De La Haza has been involved in the development of NDT methods, working closely with federal agencies and equipment manufacturers, such as the Federal Highway Administration (FHWA) Nondestructive Testing Laboratory in McLean, Virginia, the Federal Institute for Material Testing and Research (BAM) in Berlin, Germany, Acoustic Control Systems (ACSYS) in Moscow, Russia, and UTSI Electronic in Cambridge, UK. He is knowledgeable in a variety of NDT methods, including: ultrasonic shear wave method (UST), impact-echo (IE), impulse response method (IRM), ground-penetrating radar (GPR), infrared thermography (IR), ultrasonic pulse velocity (UPV), and others.
