Blueprints is an old time term for construction documents. Construction documents is the proper term for the drawings and specifications that you will need to file with the building department or bid contractors to get your work constructed. Generally, the absolute minimum drawings included will be architectural sheets to show new walls, drawings showing any demolition, plumbing drawings, mechanical drawings, electrical drawings. If you are building a new building or making structural changes to an old building then you will need structural drawings.
For exterior work you will need civil engineering drawings and an architectural site plan. Generally for buildings, these drawings come from an architect who will sometimes hire a specialist for things like structural. However, this is not always so. If your work is only a parking lot then you may only need a civil engineer. If you are only doing electrical work then you may only need an electrical engineer’s drawing. Everything is project specific and no two projects are alike.
