Very true Bill, but, in other locations of the GSN and Job Specifications it will often call out the edition that was used when in design and sometimes that is to be used for inspections while somewhere else stating the "latest edition". I have gotten the response that '2006 was the latest edition when it was designed, permitted, and approved for construction'.
So, which is it? The latest edition when the engineer designed it? Or the latest edition period? Either way, I usually have my 2006, 2008, and 2010 editions on hand. If there is a conflict we take it to the engineer.
Have a Great Day, Brent
