People still say “blueprints.” Professionals usually mean construction documents (CDs) — the coordinated drawings and specs used for permits and building. The words are not interchangeable.
Blueprints (historical term)
Originally a reproduction method with white lines on blue paper. Today the word is casual shorthand for “the drawings,” but it does not define a professional phase.
Construction documents
A set of drawings and specifications detailed enough for permitting, bidding, and construction. They coordinate architecture with structure and systems as required.
What CDs are not
- Not napkin sketches
- Not furniture mood boards alone
- Not a guarantee of zero change orders
- Not always full interior detailing unless scoped
Why the distinction matters when quoting fees
Producing CDs is a major phase of work. A cheap “plan” that is really a schematic is not a CD set — compare deliverables carefully.
