Historic Preservation Technical Procedures
As public steward of many historic federal properties, GSA has developed technical procedures to be used in specialized historic preservation work, as well as general evaluation, maintenance and repair of older building materials.
GSA has compiled this preservation information for public use in order to:
- provide detailed instructions on maintaining and repairing older and historic buildings
- improve the quality and consistency of maintenance and repairs on historic buildings
- improve knowledge, skill, and experience of the interested public by providing technical information for their education and use
These procedures are organized within each category by the Construction Specifications Institute (CSI) index number. Within each category are specifications and resources for the maintenance, standards, and repair of historic buildings.
- All Procedures
- Preventive Maintenance Procedures for routine and cyclic maintenance activities
- Standards containing background references and support data
- Repair Procedures for the correction of material deterioration and failure
The following are resource documents used within the procedures
- NPS Preservation Briefs
- NPS Preservation Tech Notes
- Guidelines for Rehabilitating Historic Buildings
- Characteristics, Uses and Problems
- Reading Lists
Work procedures designed for historic preservation are intended to be conservative in their approach and to cause no irreversible damage. Providing complex and technical information to a broad audience requires the procedures to be clear and precise, as well as to establish the context in which the information should and should not be used. Caveats have been included in capital letters at the beginning of selected procedures. These caveats provide guidance to users about the interests and limits of the procedures and the inappropriate application of procedures to materials or deficiencies where they do not apply.
Any additional suggestions or feedback on the site or the listed procedures are welcomed. Please feel free to contact Caroline Alderson
