From Grime to Sublime: Standards for Cleaning Masonry Buildings
October 10-11, plus special workshop on October 12, 2014


Sponsored by the AIA Historic Resources Committee, the Frank Lloyd Wright Foundation, and the Architectural Specialty Group of the American Institute for Conservation of Historic and Artistic Works

The maintenance, repair, and rehabilitation of existing buildings often include cleaning the exterior surfaces of stone, brick, terra cotta, and concrete. There are philosophical, aesthetic, technical, scientific, and economic factors that should be considered when specifying materials and methods for cleaning. What is the masonry material, and what is the cause and composition of soil? Is the soiling damaging the masonry material? What are the owner’s expectations? What is an appropriate aesthetic target for the character of the building? Is the patina character defining? Will a particular cleaning approach result in short term appeal and long term damage? Is the masonry best left alone? What is an optimum cycle for recleaning that balances the applicable factors? In summary, how do we characterize soiling, how should one clean a building, and ought one to clean a building, and what is the meaning of “clean?” 

The program will open with an outdoor desert terrace reception followed by the keynote lecture on Friday evening, October 10, 2014, and an evening tour of Taliesin West by staff, faculty, and students. The core of the program consists of presentations and discussion with the speakers on Saturday October 11, 2014 plus an optional advanced workshop on Sunday, October 12th.

You're Invited to Attend the First Conference on Preservation and Stewardship of Historic Places, in Yellowstone National Park,

This conference is for those historic and rustic architecture practitioners who are looking to build new skills and network with professionals and craftsman in the field. The conference will provide opportunities to learn and exchange ideas through demonstrations, classroom presentations hands-on experiences and facilitated dialog.

Presentations will cover topics such as: conducting annual inspections; assessing the condition of rustic buildings; choosing a qualified engineer and/or consultant; developing log, wood, or masonry preservation treatments and implementing treatment and maintenance plans. The Old Faithful site is also an appropriate setting for discussions about the effects of environmental factors on rustic architecture, such as winter snow loads; safety hazards for guests and contractors during the work; and how to select and source sustainable preservation alternatives. Participants can earn up to 16 AIA CEU continuing education credits.

Conference registration fee is $425 per person. However, those registering on or before August 31, will receive a special discounted Early Bird rate of $395. Lodging is available at several in-park hotels, including the historic Old Faithful Inn, and should be reserved as soon as possible to ensure availability.
