I have scanned large format documents by simply using a flatbed
scanner @ 600dpi to get overlapping coverage of all the pieces.  Then
I fed into Microsoft ICE and it stitched them together in a second or
two and worked great.

I usually do scanning at work using an 11x17" flatbed scanner/printer/copier
and it works great for most drawings in manuals I scan.  For oversize
items I scan in 11x17 chunks that overlap and then stitch.  Works great.

For blueprints, I scan to "black and white" to get a higher contrast
scan.  (The "blue" in blueprints has to do with the printing process,
not an intrinsic desire to have blue ink present.)  If 600 dpi is too
low to resolve details, then you might try a specialty shop.  The only
problems I've had with 600dpi has been crappy originals, not the scan
density.  600dpi is enough to resolve the individual half-tone dots in
most half-tone printing.
