US National CAD Standard, NCS 3.1-07, for Electrical Design

Thomas Mason, P.E.

This course narrowly focuses on completion of the Statement of Compliance required by the April, 2007, version 3.1 of the US National CAD Standard (NCS 3.1-07). Details and discussion are restricted to electrical design, though the majority of the standard is directed toward Architectural content. The full standard is copyrighted and can be purchased from National Institute of Building Sciences, 1090 Vermont Ave, NW, #700, Washington, DC 20005-4905.

The CAD standard provides a means to encourage uniform, quality presentation of facility construction drawings. It has been adopted by the federal and state governments for some projects of some agencies. The author is presently preparing engineering standards for a large municipal government and using NCS 3.1-07 as the basis. The “uniform, quality presentation” simplifies revisions and follow-up projects without a learning-curve of becoming familiar with the original design conventions followed. Backgrounds can be reused without extensive fix-up. Pen assignments are explicit so that new line weights are consistent with the original. The second designer knows where to look in the set for information left by the first designer.

The course is made up of two major parts - the Worksheet for the Statement of Compliance and the Course Content, including introduction and references.

The course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

* This course is acceptable to all the state PE boards except the New York State PE & PLS Board.
