The Sepia List is used as a means to update the Standard Drawings. The Sepia List is a list of drawings that are either:
- A new detailed drawing that is approved for use as a Standard Drawing, but is not yet found in the Standard Drawings book;
- A new detailed drawing that is under consideration and is awaiting approval for use as a Standard; or
- A revision to a detailed drawing that is currently in the Standard Drawing book.
The revisions listed on the Sepia List supersede the drawing found in the current Standard Drawings book. The Sepia drawings are inserted by the designer into the plan sets as applicable. The drawings listed on the Sepia List are put into the Standard Drawing book when a Standard Drawing revision or reprint occurs. (This generally occurs once every four years at the same time of the Standard Specification reprint.)
