Here is a comment received on the blog entry, "Too Much Information (Part 3)." 


Hi Brian,


I read your blog about the size of the AASHTO LRFD Bridge Specifications on the ENR web site .  You comment:


“For bridge engineers, the issue is graphically illustrated by the thickness of the AASHTO bridge design code. Back in the day, the code fit in a modest loose-leaf binder. More recently, just the annual updates of the new LRFD code are thicker than that. The full current code can no longer fit in one binder, and two extra thick binders are now issued.”


A few years ago I made a presentation at a G-I GeoCongress titled “LRFD: The Good, the Bad, and the Ugly (An Update).”  Among my slides was the one below. 

I’ve not updated it recently but I suspect the trend still holds now that the code requires two binders.


All the best,
