Agreed, it seems wildly optimistic to me. I was working at a military installation command last year and it would often take 6 months just to survey some existing buildings for renovation + repurposing and trying to get those plans approved. Stuff like "repaint these walls, mitigate mold, and install sub-divided chain-link fence in this warehouse" was busting our timelines. I'm assuming that just getting the paperwork right for a Federal government construction project is an equally-huge lift.
