I find it pretty ridiculous for the board to put this reference on the construction depth exam, btw every site I have found it has it on backorder so good luck acquiring it. My company has all the 2009 ACI Manuals of Concrete Practice (6 volumes in all) and they have about 18 of the 22 specs called out. If I acquire the remaining 4 I should be in good shape right? The updated ACI spec's have marginal changes and based on everyone's opinion from the last exam this reference was hardly touched. I'm not going to keep spending money just to satisfy the board, for the board to throw out ACI 318 from the construction exam and replace it with this field manual is quite shocking to me.
