Title of Treatment: Survey & Document Windows
Class of Treatment: [ ] Maintain, [ ] Stabilize, [ ] Repair, [ ] Upgrade, [ ] Exception
Type of Treatment: [ ] Traditional, [x] Contemporary, [x] Conservation
Condition to be Treated:
There is no clear written record of the types of windows, their location or construction details.
Create a comprehensive documentation that shows the types of windows in the building and how the types are different from each other. The purpose of this work is to document the types of windows and their construction; it is not to determine their condition or specify their treatment.
• Name for each window type
• Brief written description of the type
• Typical measurements for overall width and height of sash space
• Thumbnail sketch representing the type
• Location of each window on plans or elevations with numbers
• Exterior and interior elevation sketches showing all components
• Sketches of cross-sections of sill, jamb and header
• Detailed measured drawings for each type
1. Prepare for efficient work onsite. Plan for sufficient access to the windows. Gather together survey and documentation gear.
2. Sketch floor plans or elevations of the building and develop a window numbering system, if one is not already available. Identify the location of each window on the plan or elevation and give it a number. Typical numbering systems use the pattern 00x, 10x, 20x, 30x, ..., for each floor level of the building, with the number on each level incrementing by ones going clockwise around the floor plan, or from left to right across the front exterior elevation and continuing around the building. Numbering systems that use north, east, south, west can become confusing.
3. Quickly walk around and through the building to note the different window types. Observe the windows' differences and similarities of construction and purpose. Place similar windows in groups, noting the characteristics of each group in writing. Note the typical size of each window type, allowing for some variation in size within each type. Determine window size by measuring the width and height of the sash space.
4. Document each type of window with a name, a brief written description, typical measurements for overall width and height of sash space and a thumbnail sketch representing the type.
5. If needed, develop exterior and interior elevation sketches showing all visually apparent components; sketches of cross-sections of sill, jamb and header; detailed measured drawings for each type.
- This drawing shows the details required to document existing historic windows. The specific information needed about each element is noted in the parentheses. The section drawing on the right shows the relationship of the window sash to the exterior wall plane. (click on image to enlarge)
6. Write a draft report that briefly presents each type of window. Double check details onsite for accuracy. Write final written report.
• Pencils and pens
Quality of Results
Best Work: Comprehensive inclusion of every window on the plans or elevations. Neat appearance, concise presentation, easy to read and understand at a glance. Sketches are plain and easy to view.
Inadequate Work: Some windows or types not included. No measurements, no written descriptions.
