Schedules are charts of information used to describe such items as doors, windows, appliances, materials, fixtures, hardware, concrete reinforcing, and finishes. Schedules help keep drawings clear of unnecessary notes. Items in the schedules are keyed to the drawing with identification letters, numbers, and symbols. When using door and window schedules, for example, the key can label doors with a letter and windows with the number placed in different geometric shapes.
