Assets > Architectural Drawings

Goal

For each property, develop and maintain CAD architecural drawings (starting with floor plans) that relate to other information and communication management systems. Drawings will serve as the basis for describing “as built” conditions, existing conditions, proposed work, location for samples, preservation activities including risk management, treatments.

Recommendations

  1. Insure preservation, integrity, care and safety of the buildings, collections and occupants by using architecural drawings as the basis for future preservation work.
  2. Augment effective and appropriate interpretation and educational programs by employing the drawings to help in understanding the evolution of the structures, their preservation, and to create exhibits and interactive educational tools for both staff and visitors.
  3. analyze programming and space issues, use the drawings to both help programming and restoration of the interior spaces and examine the options of using additional (perhaps new) space for storage and offices.
  4. Inventory and assess all architectural drawings in files of Properties Departments; in Archive, and elsewhere.
  5. Determine which drawings should be in the Archives, and which sould be considered non-archival.
  6. Purchase architectural flat files to replace those in the Archives and Properties Department.
  7. With reference to Standards for Architectrual Drawings, identify and/or develop CAD measured drawings of all structures. Employ these as the sole and standard set of drawings which all parties should reference on any work.
  8. Reference and update these drawings in concert with storage, inventory, interpretation, maintenance, conservation, and planning efforts.
  9. Employ this same format for CAD drawings for all houses recorded by consultants. These are available, in part, and likely in a different format for the Isaac Bell House; The Elms; The Breakers.
  10. Obtain digital copies of electronic records from architectural firms that have worked on recent projects.
  11. Require all future consultants and contractors to provide electronic copies of all drawings. As needed, require consultants to adhere to specific graphic, digital, and data formats to be consistent and usuable with in-house records.
  12. When available, employ JPG or TIFF images of existing drawings (not in CAD format) as baseline images for developing future measured architectural drawings.
  13. HABS Documentation
    1. Download and use TIFF images of those structures documented employing HABS standards.
    2. Employ the HABS drawings for Château sur Mer as baseline images for drawings to be developed for upcoming preservation work.
    3. Print out sheets of all HABS drawings of Society properties.
    4. Print out architectural drawings of each structrure and retain a complete set on the site and available to emergency response teams.
  14. Amend all construction drawings by developing "as-built" drawings after any construction work is completed.
  15. Relate with Infromation and Communication Management.
    1. Relate drawings (including their schedules, and related specifications) to databases developed for Infromation and Communication Management.
    2. Using stuctures what have adequate documentation based on recent projects (Isaac Bell House; Breakers roof restoration), identify pilot projects for using existing drawings, and relating these to databases and stewardship. Consider the Isaac Bell House.
    3. Identify pilot projects for recording structures and integrating existing and newly-developed databases. Consider Château sur Mer.
  16. Locate orginal prints of historic drawings.
  17. Employ the following data fields for drawings:

    Notes

To care for existing architectural plans:

  1. Inspect each plan as it is arranged and described, looking for fading, discolouration, acid damage, dirt, and tears, especially along fold lines.
  2. Remove particularly damaged items from use until they can be cleaned and repaired.
  3. To prevent fading, especially of photographic item such as blueprints or photostats, keep maps and plans away from bright lights.
  4. Flatten all folded, creased, or rolled material. Place face down between clean acid-free blotters on a flat surface, holding it down with a piece of plywood large enough to cover the entire document. Hold with light weights. Several documents can be flattened at one time in this way, but they need to be left for at least 24 to 48 hours. Check them periodically to ensure they are flattening well and remove them once they show no signs of curling.
  5. Plans that will not flatten easily may sometimes be moistened first. Be extremely careful if you attempt this and always check that the inks are not water-soluble. If necessary, build a relaxation chamber to unroll maps.
  6. Remove smaller wrinkles and bends in maps and plans by sponging the area lightly with water and pressing the document between weighted acid-free blotters. Change the blotters frequently to remove excess moisture. Again, watch for water-soluble inks.
  7. Clean the surface of plans if necessary. Remove dirt and dust carefully, using light brushes and artgum erasers. Also lift off any loose tape.
  8. Repair minor tears with archival mending paper or tape, applied only to the back of the document. Never use adhesive tape, rubber cement, paste, or glue on any archival material.
  9. Store maps and plans in a room with adequate temperature and humidity controls and protected from flood or fire.
