    I took PDD and did not pass.  Afterwards I purchased AGS 12.  Many of the details appear to come directly from AGS 12.  It is probably no coincidence that AGS 12 and ARE 5.0 were released at about the same time.

    Brendan,

    I guess let me offer this: I'd be very, very, very surprised if you had to analyze the specifics of an exact fireproofing detail on this test.  If you were to get a question related to a fireproofing detail, here's examples of what I think they could be, generally speaking:

    1) Here's a wall assembly rated for this many hours.  Pick from these four options an appropriate firestop assembly for a 4" diameter pipe through the wall.

    2) Here's a building of construction type X.  Here's the appropriate table in IBC for structure ratings.  What rating is required for the columns?  Or maybe, what fireproof assembly from the options below meet the requirements for a column?

    I say this because I'm not sure what payoff you'd get from staring at actual assemblies, which would show the thickness of the fireproof spray, or the width of the firestopped putty joint around a pipe penetration.  I suppose if you have very little experience with this in your work, you might want to take a look at what these look like just to see them graphically, but I don't think you should focus your efforts on any type of memorization.  Know HOW these elements get firestopped or fireproofed, as in, be familiar with what methods are out there.  Maybe you'll get asked what type of assembly would be appropriate for an exposed column in a high-profile main entry lobby.  Well there, you wouldn't want an ugly fireproofed sprayed column, so you'd instead opt for something with intumescent paint perhaps.  That kind of thing. 

    If you'd like to see some examples, I recommend going to Hilti's website or STI's website.  You'll be able to see installed images as well.  A fireproof spray assembly - check out Cafco or Isolatek International.  You can find some examples of UL rated fireproof spray assemblies for beams and columns.

    Hope that helps!

    Does anyone know how different AGS 12 is from older versions (10 or 11)?

    Brandon, I actually just signed up for AGS digital subscription to check it out. I may just use this rather than purchasing the book given all the negative reviews it has recently received due to its format and lightweight usage. Firesafing showed up multiple times on my PDD exam last time so I want to have a better understanding of it along with general wall assembilies.

    Darci, I have not owned prior editions of AGS but you may have read my comment above.  I got a new copy from Amazon for $120 (price fluctuates - keep an eye on it).  I figured it was a small price to pay since I am paying to retake PPD and PDD.  My big gripe with the AGS 12 is that the publisher screwed up the gutter - each side of the book needs an additional 3/8" in the gutter.  Simply shoddy work.  Glad I didn't buy it from the publisher.  Otherwise, I think the book is fine: binding is good quality and all else is OK.  It is re-organized from previous versions though - it follows a "project" format just like ARE 5.0 claims to follow.  Again, it's no coincidence that NCRAB release 5.0 and AIA releases AGS 12 about the same time, both based on this new format.  And having taken PDD, yes there are details that come from AGS 12.  No, I don't work for Wiley lol.  If you can afford it and plan on getting your license, it might be a good reference, especially for PDD.  The PDD test crashes and locks up so having extra study material and knowledge would be one less stress, IMO.
