I just worked on an IT RFP response for a State for a similar number where we only had about a month to craft the response. Damn thing came in at like 1200 pages too. Issuers don't care if the bidders have to kill themselves to make the dates.
At my old company we wouldn't bid sometimes because we just didnt have the time. Then I'd get a call after the deadline passed nicely asking me to please bid. The implication being because they either. A. Didn't get enough bids to satisfy the internal requirements or B. they liked my number on a historical basis.
But yeah, some of those really suck.
