Resistance Drilling, shown here at Drayton Hall in Charleston, charts the change in resistance as a very thin drill bit moves through softer, rotted wood. Produces paper print-out that conservators use to pinpoint rot or voids.

APT International in conjunction with the APT Hawaii-Pacific Islands Chapter announced a workshop on  Nondestructive Evaluation Methods for Historic Structures to be held in Honolulu on April 11-12, 2013.  This workshop is funded in part by NCPTT. The purpose of this Workshop is to provide guidance for designers, engineers and contractors in the use of diagnostic non-destructive testing for historic structures.  The two-day workshop is intended for graduate engineers and for practicing engineers who are not familiar with the subject area, and technically oriented professionals from other disciplines.  The program is divided between lectures on the first day and hands-on field sessions on the second day.  For more information or to register go to the APT website.
