RE: "Electronic" signatures

[Subject Prev][Subject Next][Thread Prev][Thread Next]
First, Dallas is no hotter or drier than Lubbock!
I have no expert knowledge of digital signatures, other than their use
with Netscape and IE4 to verify certificates, etc.  I don't think that
this is what you refer to in the first paragraph of your message. 
Someone out there must have relevant input, however.
With respect to your second paragraph, you should study the latest
version of the Texas PE Board Rules, which can be conveniently
downloaded as an Adobe PDF file at:  ; Section 131.166 addresses the
subject of engineer's seals.  I think your concept is sound, as long as
the scanned version is nothing more than a reproduction (of course, file
sizes could be huge).  However, you should be aware that Board Rule
131.166(g) states that "... Signature reproductions, including but not
limited to rubber stamps or computer-generated signatures, shall not be
used in lieu of the engineer's actual signature."  There is no longer
any problem with CADD generated seals in Texas.  The issue is with
anything other than manual signatures.  Before you spend a lot of money
on hardware, it might be a good idea to call the PE Board and talk with
them.  Then, if you get a favorable interpretation, follow it up in
With respect to an earlier thread on plan stamping, the Texas PE Board
Rules are now very specific on the consequences.  Aiding or abetting
unlicensed practice in any way, including plan stamping:  3 year license
suspension plus a $3000 fine.

Subject: "Electronic" signatures

To all, esp Stan in the Dallas heat . . . 

Our company is currently in the process of purchasing several high
volume plotters at which the following point came up.

The models we are looking at have the capability to run multiple
collated copies on plain paper media.  This in effect would allow us to
eliminate the blueline monster (and its associated high labor costs, not
to mention repair) in our reproduction department, if digital
"electronic" signatures were permitted.  Someone had said that there has
been recent changes with regards to this concept.  Is this true?

The other option would be to plot a single copy, affix signature and
then use the machines' scanning option (sold seperately) to produce the
construction document sets.  would this be any different than a blueline
print in the eyes of the TX state board, and others?  It is still a
reproduction of the signed "original".  Any thoughts or comments are
appreciated in advance . .
