PE Requirements:

Digital signature and stamp to show metadata next to stamp.

The Nevada Board of Professional Engineers (NRS 625.610) requires that each design professional add their digital signature to the first page of each discipline in combination with a stamp, expiration date, and date of signature on each sheet. The digital signature guide can be found here: https://nvbpels.org/wp-content/uploads/2020/11/Digital-Signature-Guide-FINAL.pdf Please refer to page 4 of this document, which shows an example of the format needed for the digital signature. The text that begins with "digitally signed by..." in the example image is required as part of the digital signature.

Non Standard Revision Requirements

Plans will be rejected if you do not follow these instructions and items below.

1. On the top of the narrative document list the revision number BDxx-xxxxx-R00x (this is the Permit number [Ex: BD22-37660] then "-R00" and whichever revision number the narrative is for [Ex: BD22-37660-R003] if it were the 3rd revision requested)

2. Identify in the narrative the pages that have changes in a list format. Each drawing, sheet or page should be a separate line item. Next to each page number, describe the changes for that page in detail. Do not use “general” statements.

3. The revised drawing, sheet or pages shall have a cloud around the area(s) which were changed, and a numbered delta symbol used to identify the submitted revision. Clouds around the entire drawing will not be accepted.
