The day I found a blueprint from 1968 in a renovation project
Pulled open a wall in an old office building downtown last Tuesday and found a hand-drawn hvac layout rolled up inside, complete with coffee stains and someone's initials from way back. It was spot on for what we needed to match ductwork to the original design. Anybody else ever find old plans hidden in a building?

Respectfully, old prints are often outdated and not worth chasing.

Nah man I gotta hard disagree with @webb.val on this one. Old prints are gold if you know what to look for, especially when you're dealing with a building from that era. The materials and methods back then were totally different from what we use now, so trying to match modern stuff to old construction without the original plans is a gamble. I've found old blueprints stuffed in ceilings and behind panels a few times and they saved me hours of guessing where pipes and ducts actually run. Those guys who drew them knew their building inside out, plus you get the original engineer's notes which can clue you into weird quirks or shortcuts they took. Outdated doesn't mean useless, it means you have a reference point to check against what's actually there now.
