Because 1) there is nothing in the document about it being a shared resource (copy at
https://www.wabe.org/wp-content/uploads/2019/09/LSJ_Hyper_Re... ), and 2) the FBI already has such facilities, like 'Hogan's Alley' at Quantico (
https://en.wikipedia.org/wiki/Hogan's_Alley_(FBI) ). There are many other similar facilities, like in Artesia, NM
https://www.fletc.gov/artesia-new-mexicoNow, the document claims that this will be a "hyper-realistic" facility, and that only one company is able to provide such unique capabilities.
This leads to some obvious questions: 1) if hyperrealism is so important, why aren't the other facilities, including the FBI, already asking for improvements to their existing sites? 2) why should there be new sites for these sorts of training facilities - what tactical training abilities aren't already available? and 3) if it's so important, why isn't it explicitly being developed as a shared resource?
I think the bureaucratic is more reasonable than the one proposed by the grandparent post, that is, each federal organization acts as its own fiefdom and wants its own things. Plus, there's probably some graft - is it really the case that only a single company can provide such construction?
