  1. The Preservation Principles of the Secretary of the Interior’s Standards for Historic Preservation Projects David W. Look, FAIA, FAPT National Park Service Pacific West Region Oakland, California

  2. Approach • Better to Maintain than Repair • Better to Repair than to Replace • Better to Replace than to Restore • Better to Restore than to Reconstruct

  3. Approach of Historic Architects • “If all historic buildings andsites were well maintained, there would seldom be a need to restore, rehabilitate, or reconstruct except for the updating of systems.” • You are only a success as an Historical Architect if no one knows you were there after you finish working on a historic building.Lee H. Nelson, FAIA

  4. Approach of Modern Architects • “All great architecture is unique and the only great architects are those that create unique buildings.” • “It is impossible to know and meet the clients needs 20 to 30 years from now so architects are wasting the clients money if they construct monumental buildings with materials that will last forever.” Prof. Claude Winkelhack

  5. Best ApproachMaintenance is theBest Form of Preservationand the Least Expensive

  6. Why Does This BuildingHave a Water Problem?

  7. Deferred MaintenanceCosts 3-5 Times MoreThan PreventativeMaintenance.If Maintenance is DeferredToo Long, the ResourceMay be Lost Forever.

  8. What Principles Guide Work in Historic Preservation?

  9. Fundamental Principles • Research & Documentation • Authenticity & Integrity • Compatibility • Minimal Intervention • Reversibility

  10. Research & Documentation • Research is investigation aimed at the discovery and interpretation of facts, the revision of accepted theories in light of new facts, or the development of practical applications of such new revised theories [National Park Service].

  11. Research

  12. Documentation • Documentation is compilation of both graphic and written records that explain and illustrate the significant characteristics of a historic building, site, structure, or object. During research and treatment further documentation is made to record what was done and why.

  13. Documentation

  14. Authenticity • Authentic is defined as having an undisputed origin; genuine [The American Heritage Dictionary of the English Language]. • Authenticity is the condition or quality of being authentic, trustworthy, or genuine [The American Heritage Dictionary of the English Language].

  15. Authenticity

  16. Integrity • Integrity is the authenticity of a property's historic identity, evidenced by the survival of physical characteristics that existed during its historic or prehistoric period; the extent to which a property retains its historic appearance.

  17. Integrity “Do You Still Have Your Grandfather’s Ax If It Has Had 3 New Handles and 3 New Blades?” Lee H. Nelson

  18. Seven Qualities of Integrity • Location • Design • Setting • Materials • Workmanship • Feeling • Association

  19. Location Quality of integrity retained by a historic property existing in the same place as it did during the period of its significance Historic Building and Cultural Landscape have Never Been Moved

  20. Design Quality of integrity applying to the elements that create the physical form, plan, space, structure, and style of a property

  21. Setting Quality of integrity applying to the physical environment of a historic property

  22. Materials Quality of integrity applying to the physical elements that were combined to or deposited in a particular pattern of configuration to form a historic property Building with 95+% Integrity and Mature Specimen Trees that are 75-100 years old

  23. Workmanship Quality of integrity applying to the physical evidence of the crafts of a particular culture, people, or artisan

  24. Feeling Quality of integrity through which a historic property evokes the aesthetic or historic sense of past time and place

  25. Association Link of a historic property with a historic event, activity or person. Also the quality of integrity through which a historic property is linked to a particular past time and place Will always be associated with the Agronomist Hoshino Shūtarô, the Luther Burbank of the Pacific, and the research done here during the Japanese and American Periods; the Art Deco Engineer/Designer, Yamashita Yasaburô, who also designed the Saipan Hospital & the Palau Courthouse in the Art Deco Style; and the early history of the FSM

  26. Integrity of Material &/or Design

  27. Compatibility • Compatibility is the principle that no treatment shall detract from or cause damage to a cultural resource. This includes both visual and physical compatibility. Treatments and new work shall be visually compatible in terms of design, color, texture, massing, size, scale, and other visual qualities to protect the historic integrity of the property and its environment. Likewise, the treatments and new work shall be physically compatible with the historic materials in terms of coefficients of expansion and contraction with changes in temperature, shrinking and swelling with changes in moisture, hardness, etc..

  28. Visual Compatibility • Treatments and new work shall be visually compatible in terms of design, color, texture, massing, size, scale, and other visual qualities to protect the historic integrity of the property and its environment.

  29. Visual Compatibility

  30. Physical Compatibility • Treatments and new work shall be physically compatible with the historic materials in terms of coefficients of expansion and contraction with changes in temperature, shrinking and swelling with changes in moisture, hardness, etc.

  31. Physical Compatibility

  32. Minimal Intervention • Minimal intervention is the principle that usually the less change or alteration done to a cultural resource the more integrity the resource retains. If each generation makes major changes or alterations to a resource, sooner or later there is little or no resource left to preserve and pass on to future generations.

  33. Minimal Intervention

  34. Reversibility • Reversibility is the principle that nothing should be done to a cultural resource that cannot be reversed or undone without permanent damage to the resource. In the future there may be better treatments. If irreversible treatments are undertaken, the cultural resource may have permanent damage and may be prevented from better treatments developed in the future.

  35. Reversibility • Simone Rodia Towers NHL, Watts, CA

  36. Reversibility

  37. Secretary of the Interior’s Standards for Rehabilitation David W. Look, FAIA National Park Service Pacific West Region Oakland, California

  38. PreservationWork, including preliminary measures to protect and stabilize the property, generally focuses upon the ongoing maintenance and repair of historic materials and features rather than extensive replacement and new construction.

  39. Secretary of the Interior’s Standards for Historic Preservation Projects Preservation Restoration Rehabilitation Reconstruction

  40. Standards are based on: Research & Documentation Authenticity & Integrity Compatibility Minimal Intervention Reversibility

  41. Preservationis defined as the act or process of applying measures necessary to sustain the existing form, integrity, and materials of an historic property. Work, including preliminary measures to protect and stabilize the property, generally focuses upon the ongoing maintenance and repair of historic materials and features rather than extensive replacement and new construction. New exterior additions are not within the scope of this treatment; however, the limited and sensitive upgrading of mechanical, electrical, and plumbing systems and other code-required work to make properties functional is appropriate within a preservation project [NPS].

  44. Preserve

  45. Preservation Focuses on the Maintenance and Repair of Existing Historic Materials and Retention of a Property’s form as it has Evolved Over Time

  46. Rehabilitation is defined as the act or process of making possible a compatible use for a property through repair, alterations, and additions while preserving those portions or features which convey its historical, cultural, or architectural values [NPS].

  47. Rehabilitation Acknowledges the Need to Alter or Add to a Historic Property to Meet Continuing or Changing Uses While Retaining the Property’ Historic Character
