Historic Structures Report
MATERIAL DESCRIPTIONS, CONDITIONS AND REPAIRS
Our philosophy is that the rehabilitation, restoration,
preservation or stabilization of a structure should have a minimal
impact on historic fabric. Deficiencies that threaten life and safety,
or that are causing deterioration must be corrected. The value of any
other improvements should be weighed against the value of the building's
integrity. The historic fabric and character-defining features of these
structures were described earlier in this report. The following
recommendations, extracted from Director's Order 28 (DO-28), Cultural
Resource Management Guidelines, apply to all treatments.
Use is monitored and regulated to minimize both immediate and
Use of destructive techniques, such as archeological excavation,
is limited to providing sufficient information for research,
interpretation, and management needs.
All work that may affect resources is evaluated by an historical
architect and other professionals, as appropriate.
All modification, repair, or replacement of materials and
features is preceded by sufficient study and recording to protect
research and interpretive values.
New work, materials, and replacement features are identified,
documented, or permanently marked in an unobtrusive manner to
distinguish them from original work, materials, and features. The manner
and location of identification is recorded using the Inventory and
Condition Assessment Program (ICAP). The ICAP program will be updated
and modernized in FY2000, and may become known under a different
A proposed treatment project is initiated by the appropriate
programming document, including a scope of work and cost estimate from
an HSR or ICAP. Such projects include preservation maintenance as well
as major treatment. No treatment is undertaken without an approved HSR
or work procedure documenting the work, and Section 106
A treatment project is directed by an historical architect and
performed by qualified technicians.
Representative features salvaged from an historic structure are
accessioned and cataloged, provided that they fall within the park's
scope of collection statement.
All changes made during treatment are graphically documented with
drawings and photographs. Records of treatment are managed as archival
materials by a curator or archivist within the park's museum
As with any historic building, the State Historical Building Code and
the Uniform Code for Building Conservation should be used as the
prevailing codes. This allows for sensitive, performance-based means for
achieving a safe, improved structure.
