Design Infomation Required on Drawings
(OP)
In the Canadian steel code S16-09 Clause 4.2.2 (c) states that the design criteria for snow, wind, seismic and special loads shall be given in the design documents.
Is it sufficient to just include a note on the drawing stating that the design was carried out in accordance with the National Building Code of Canada (latest edition) or does the clause above require more design specific information?
When descibing the snow load criteria for example, I typically give the ground snow load, rain load, importance category, and wind exposure coefficient in the general notes on my drawings. And likewise for wind and seismic I give the values of all of the coefficients required to determine the forces I used in my design.
Is this going too far since, theoretically, all of the coefficients could be found in NBCC? I am curious to know what other engineers specify.

Then usually list the design dead/live loads.

I have a problem.
Usually I work with eurocode and now I have to convert a design started with the eurocode to the usa code (ACI, ASTM,ASCE etc).
There is someone that is able to list the most important material specification necessary to put on drawings and in a report?
Thanks a lot in advance for your help.

I attached some typical notes I have used to illustrate. (I apologize for the scan quality)

I don't have the code in front of me, but if I remember correctly for seismic loading they require:
Ss,S1,Sds,Sd1,Site Class, Importance Factor, R, Base Shear, Method of analysis, Framing system etc....
All this information is required to calculate the load and is required to be placed on the drawings.
