Blueprint Construction Plans
I would like to direct your attention to a PDF from archive.org that preserves a special 1946 supplement to American Builders Magazine.
Blueprint Plans from American Buidler Magazine (1946) archive.org
The full PDF at archive.org weighs in at 99MB (78 pages) and would probably take seven years to download, so I’ve broken off two selections into smaller pieces that should be easier for our network connection to digest:
- A Modern Adaptation of a French Farmhouse (9.3MB): blueprint-plans-pages-1-to-8
- Modern Design for a Sloping Lot (6.4MB): blueprint-plans-pages-24-to-29
If you ever have the time, check out archive.org for more architecture and design related documents. Let me know if you find something interesting.
A blueprint is a reproduction of a technical drawing, documenting an architecture or an engineering design, using a contact print process on light-sensitive sheets. Introduced in the 19th century, the process allowed rapid and accurate reproduction of documents used in construction and industry. The blue-print process was characterized by light colored lines on a blue background, a negative of the original. The process was unable to reproduce color or shades of grey.
Various base materials have been used for blueprints. Paper was a common choice; for more durable prints linen was sometimes used, but with time, the linen prints would shrink slightly. To combat this problem, printing on imitation vellum and, later, polyester film (Mylar) was implemented.
The process has been largely displaced by the diazo whiteprint process and by large-format xerographic photocopiers, so reproduced drawings are usually called “prints” or just “drawings”.
The term blueprint is also used less formally to refer to any floor plan (and even more informally, any type of plan). Source
