I work as an electrical designer for a California C-10 licensed electrical contractor.

When we submit drawings for plan review we have been putting a stamp on our drawings similar to a professional engineers stamp. The stamp says that we are a state of California C-10 contractor and gives our license number. The owner of our company then signs this stamp prior to sending them to plan review.

Recently we have been informed that this may not be legal as the stamp looks too much like a professional engineers stamp.

My question is what do the other C-10 contractors out there do to sign their design build drawings for plan review? Is there a state guideline availible for address this issue? If so, can you please point me to it?

Thank you.

Get a stamp that doesn't look like an engineer's stamp.

I've had one that mentions the CA Business and Profession Code section that lets C-10 do the engineering for jobs to be performed by them.

It's CA Business and Professions Code 6737.3

Also, as far as planning depts go, they need to follow the CA DSA/architechs rules on stamp placement of the stamp, size and info.... Think I found it looking for T-24 info???? Apparrently there is a hierarchy to whos stamp goes where.

(looking for but may never find it again....) Cant find it...

I place a text block on my "Cover Page", which contains the "Designed and Installed By Electrical Contractor" Disclaimer, along with License number and expiry date, and two signature lines - one for the License Holder (my boss!) - listed as "President", and one for my signature - listed as "Designer".

I also include a basic stamp in the Title Block attached to each Plan Page.
It contains signature fields, designations (Prez or Designer) and License information (number + expiry date).

We both sign each page's Title Block stamp, and the Disclaimer Note Block on the cover page.

Had no problems with Plan Checkers doing things this way (began Designing Plansets back in the 1980's).


BTW, all signatures are "Wet Signed", on each set submitted (including "LTG-1-C" and "OLTG-1-C" Lighting Compliance Forms)
