Good luck getting the pre-eng building people to do that. I've never had any luck getting any info from them, and when you ask them questions about how anything "by others" attach to their structure or is accounted for, I get the answer of "Not my problem".
An aside - I recently saw some pre-eng building plans. The anchor bolts varied by location from 5/8" dia. to 3/4" dia., and steel sections appear to be designed for least weight. In todays world where material costs (ie. weight of steel) aren't the controlling factors (fabrication usually controls), are pre-eng buildings past their prime??
