1. ARCH 5325 Conservation Policies
Chapter 7
Intervention Approaches, Documentation, and Technology

2. Most of the architectural projects today are adaptive use of historic or old buildings
Without care one can damage buildings by not understanding materials: i.e. mortar and brick, waterproofing, roofing
Historical integrity can be lost through inappropriate renovation and restoration

3. Preservation Technology is the understanding of historic building materials and methods of construction and the use of new technologies: i.e. fiberglass, glazing, waterproofing, insulation, cellulose, plaster, and stucco

4. Secretary of the Interior’s Standards for Rehabilitation
Resources
Secretary of the Interior’s Standards for Rehabilitation
treatments/treatment-rehabilitation.htm
deals with types of intervention: i.e. preservation, restoration, reconstruction, rehabilitation, and conservation/preservation of material, as in paint types, and colors and intervention with new materials as replacements for old

5. Secretary of the Interior's Standards for the Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating, Restoring, and Reconstructing Historic Buildings
deals rather broadly with the history of components (windows, doors, masonry) and materials

6. Deals with specific methods

Deals with specific methods
2 Repointing Mortar Joints in Historic Masonry Buildings
Properties of Mortar
Mortars for repointing should be softer or more permeable than the masonry units and no harder or more impermeable than the historic mortar to prevent damage to the masonry units. Stresses within a wall caused by expansion, contraction, moisture migration, or settlement must be accommodated in some manner A mortar that is stronger in compressive strength than the masonry units will not "give," thus causing stresses to be relieved through the masonry units--resulting in permanent damage to the masonry, such as cracking and spalling, that cannot be repaired easily.

Secretary of the Interior’s Guidelines for Architectural and Engineering Documentation
law/arch_stnds_6.htm
Deals with documentation methods for historic properties: i.e. for National Register properties and other historic property documentation
Includes measured drawings for HABS, HAER, and HALS; photographic requirements; written data; and historic documents
administers virtually all preservation programs of the US government

Case Study
Charles Goodnight Ranch House

9. Research Literature/Resource Search Maps and City Lithographs
Raymond Buck House—bills from suppliers
Newspaper articles
Maps and City Lithographs
Lithographs mostly done in the late 1800s and early 1900s so are not usually useful for later buildings
Sanborn Maps—are very often useful
Oral Histories
Measured Drawings—by hand or by 3D Laser Scanning
Photographic Techniques— digital, black and white, large format, infrared
