Do Not Migrate

NCPTT is sponsoring a workshop entitled APT Preservation Engineering Workshop: Non-Destructive Evaluation Methods for Historic Structures to be convened by the Association for Preservation Technology on Nov. 5-6, 2010 at the historic Presidio of San Francisco.

The workshop will provide guidance for professionals and students in the  use of diagnostic nondestructive testing for historic structures. It  is  intended  for  technically  oriented  graduates and practicing engineers,  architects,  preservation consultants, and contractors who are not familiar with this subject area.

The  workshop  will  cover  the  concepts,  theory and applications of nondestructive   test  methods  for  diagnosis  of  historic  building materials  and  structures.  It will include an overview of applicable technical  standards  and guidelines relating to diagnosis and testing of  historic  structures, discuss applicability and appropriateness of existing standards, and the role of engineering judgment.

A  key   component   of  the  workshop  is  hands-on  field  sessions demonstrating  diagnostic  test methods on actual structures. The test methods  will  include  ground-penetrating  radar,  in-place  tests of masonry,  infrared  thermography,  resistance  drilling  of timber and digital  radioscopy.  Simpler diagnostic tools will also be available, such  as  moisture meters and rebound hammers. Stations will be set-up for  hands-on  application  at  selected buildings. The field sessions will  be  set  up  to  allow  groups  of  attendees  to rotate between stations.  The  attendees  will be encouraged to make observations and discuss the condition of the buildings, alternative diagnoses, and the meaning of the test results.
