The registration deadline for this workshop is April 24, 2009. 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.

NCPTT awarded 12 projects, totaling $262,500, for preservation technology and training awards to universities, non-profit organizations, and state agencies.

NCPTT, in cooperation with the Olmsted Center for Landscape Preservation and the Cane River Creole National Historical Park has finished production of the instructional video “Replacing Trees in Historic Landscapes.”

The Conservation Center for Art and Historic Artifacts (CCAHA) developed the Architectural Records Symposium: Managing and Preserving Design Records to improve practices for preserving and providing access to architectural records in museums, archives, libraries, and historic sites throughout the country.

Swelling clays in stone can generate damaging stresses during a wetting or a drying cycle, which leads to deterioration of building stones such as Portland Brownstone.

Near-surface geophysical techniques, including ground-penetrating radar, magnetometry, electrical resistivity, and electromagnetic conductivity, have become primary tools in the detection of unmarked human interments.

We do not advocate the use of shaving cream for investigating inscriptions on stone. The shaving cream has natural emollients for softening the skin. These emollients have oils and moisture holding agents that can have detrimental effects on the stone.

NCPTT and Hybrid Plastics are partnering to make and use POSS modified polymers in preservation applications. Researchers and preservationists discussed the potential of developing new nanotechnologies for application to preservation problems.

Trees in historic landscapes are often important cultural resources that contribute to the significance and integrity of a property. This video provides guidance on the concepts and techniques of replacing individual trees at historic properties.
